DETAIL DESCRIPTION OF EMBODIMENTS

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. Further, the embodiments of the present disclosure and features thereof may be combined with each other as long as they are not contradictory. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure described herein without paying any creative effort shall be within the protection scope of the present disclosure.


Unless otherwise defined, technical or scientific terms used in the present disclosure are intended to have general meanings as understood by those of ordinary skill in the art. The words “first”, “second” and the like used in the present disclosure do not denote any order, quantity, or importance, but are used merely for distinguishing different components from each other. The word “include” or “comprise” or the like means that the element or item preceding the word includes elements or items that appear after the word or equivalents thereof, but does not exclude other elements or items. The word “connected”, “coupled” or the like is not limited to a physical or mechanical connection, but may include an electrical connection, whether direct or indirect.


It should be noted that the sizes and shapes of various components in the drawings are not to scale, but are merely intended to schematically illustrate the present disclosure. The same or similar reference signs refer to the same or similar elements or elements with the same or similar functions throughout the drawings.


In some embodiments of the present disclosure, as shown in FIGS. 1 and 2, a display apparatus may include a display panel 100 and a drive control circuit 200. In some embodiments, the display panel 100 may include a plurality of pixel units arranged in an array, a plurality of scan signal lines GA (e.g., GA1, GA2, GA3, GA4), and a plurality of data signal lines DA (e.g., DA1, DA2, DA 3). Illustratively, each pixel unit may include a plurality of sub-pixels SPX with different colors. For example, a pixel unit may include three sub-pixels with different colors, which may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Alternatively, the pixel unit may include four sub-pixels with different colors, which may be a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel. It should be noted that, in practical applications, the colors of light emitted by the sub-pixels and the specific number of the sub-pixels in the pixel unit may be determined and designed, according to practical application environments, and are not limited by the present disclosure.


In some embodiments of the present disclosure, as shown in FIG. 2, each sub-pixel SPX may include a switch transistor 01 and a pixel electrode 02. In some embodiments, a row of sub-pixels SPX are coupled to a scan signal line GA, and a column of sub-pixels SPX are coupled to a data signal line DA. Specifically, a gate of the switch transistor 01 is coupled to a corresponding scan signal line GA, a source of the switch transistor 01 is coupled to a corresponding data signal line DA, and a drain of the switch transistor 01 is coupled to the pixel electrode 02 in the same sub-pixel SPX. In specific implementation, when a scan drive signal loaded on the scan signal line GA is at an active level, the switch transistor 01 may be controlled to be turned on, so that the data voltage loaded on the data signal line DA may be input to the pixel electrode 02 through the turned-on switch transistor 01, thereby charging the pixel electrode 02, that is, charging the sub-pixel. In addition, when the scan drive signal loaded on the scan signal line GA is at an inactive level, the switch transistor 01 may be controlled to be turned off, so that the pixel electrode 02 may maintain the input data voltage through the turned-off switch transistor 01.


In some embodiments of the present disclosure, the pixel array structure in the present disclosure may alternatively be a dual-gate structure, that is, two scan signal lines are arranged between two adjacent rows of sub-pixels. This arrangement may reduce half of the data signal lines, that is, a data signal line is provided between some two adjacent rows of sub-pixels, and is not provided between other two adjacent rows of sub-pixels. It should be noted that, in practical applications, the specific arrangement structure of pixels and the arrangement manner of the data signal lines and the scan signal lines may be designed and determined according to practical application environments, and are not limited by the present disclosure.


In some embodiments of the present disclosure, the display panel in the embodiments of the present disclosure may be a Liquid Crystal Display (LCD) panel, an Organic Light Emitting Diode (OLED) display panel, a Quantum Dot Light Emitting Diode (QLED) display panel, an electronic paper display panel, or the like. Illustratively, taking a liquid crystal display panel as an example, the liquid crystal display panel may generally include an array substrate and an opposite substrate which are aligned and assembled together, and a liquid crystal molecule layer sealed between the array substrate and the opposite substrate. Illustratively, when a picture is displayed, since a voltage difference exists between the data voltage loaded on the pixel electrode of each sub-pixel and the common electrode voltage on the common electrode, the voltage difference may form an electric field, so that the liquid crystal molecules in the liquid crystal molecule layer are deflected by the electric field. The electric fields with different strengths enable the degree of deflection of liquid crystal molecules to be different, so that the transmittances of the sub-pixels are different, the sub-pixels can realize the brightness of different gray scales, and further, the picture display is realized.


In the following, it is taken as an example in the description that the display panel in the embodiment of the present disclosure is a liquid crystal display panel, and the pixel unit includes a red sub-pixel SPX, a green sub-pixel SPX, and a blue sub-pixel SPX. However, the reader should understand that the color of the sub-pixel SPX in the liquid crystal display panel is not limited thereto.


Illustratively, referring to FIG. 3, taking a sub-pixel SPX as an example, Vcom represents a common electrode voltage. When the data voltage input to the pixel electrode of the sub-pixel SPX is greater than the common electrode voltage Vcom, the liquid crystal molecules in the sub-pixel SPX may have a positive polarity, and the polarity corresponding to the data voltage in the sub-pixel SPX is a positive polarity. When the data voltage input to the pixel electrode of the sub-pixel SPX is less than the common electrode voltage Vcom, the liquid crystal molecules in the sub-pixel SPX may have a negative polarity, and the polarity corresponding to the data voltage in the sub-pixel SPX is a negative polarity. Illustratively, referring to FIGS. 2 and 3, a frame inversion (which may alternatively be a dot inversion, a column inversion, a row inversion, etc., and the present disclosure is only described taking the frame inversion as an example) is taken as an example, where, as shown in FIG. 3, ga1 represents a scan drive signal loaded on the scan signal line GA1, ga2 represents a scan drive signal loaded on the scan signal line GA2, da1 represents a data voltage loaded on the data signal line DA1, and da2 represents a data voltage loaded on the data signal line DA2.


Illustratively, as shown in FIGS. 2 and 3, the display panel may include a data refresh phase TS and a blanking time phase TB in each of different display frames F1 and F2. In the data refresh phase TS of the display frame F1, data voltages input to the sub-pixels in the display panel may be controlled, so that the display panel displays a picture of the display frame F1. Specifically, the scan drive signal ga1 is loaded on the scan signal line GA1, the scan drive signal ga2 is loaded on the scan signal line GA2, and when an active level (e.g., a high level signal in each of the scan drive signals ga1 to ga4) appears in each of the signals ga1 to ga4, the switch transistor 01, which is coupled to a corresponding one of the scan signal lines GA1 to GA4, is controlled to be turned on. For example, when a high level signal appears in the scan drive signal ga1, the switch transistors 01 in the first row of sub-pixels may all be controlled to be turned on. In addition, the data signal line DA1 is loaded with a data voltage da1 corresponding to the positive polarity, the data signal line DA2 is loaded with a data voltage da2 corresponding to the negative polarity, and the data signal line DA3 is loaded with a data voltage da3 corresponding to the positive polarity, so that the data voltages loaded on the data signal lines DA1 to DA3 are input to the pixel electrodes 02 in the first row of sub-pixels, through the turned-on switch transistors 01 in the first row of sub-pixels, so that the corresponding data voltages can be input to the pixel electrodes 02 in the first row of sub-pixels, and further, each sub-pixel in the first row can be input with the data voltage, thereby realizing the charging of each sub-pixel in the first row.


Then, in a blanking time phase TB of the display frame F1, the scan drive signals ga1 to ga4 are all low level signals, the switch transistor 01 in each sub-pixel in the display panel is in a turned-off state, and the pixel electrode 02 in each sub-pixel can be controlled to maintain the data voltage, so that the sub-pixels in the display panel can be controlled to maintain the data voltages, and the display panel can continue to display the picture of the display frame F1.


The implementation of the remaining sub-pixels is similarly performed in sequence, until charging the corresponding data voltages is finished throughout the sub-pixels in the whole display panel, which is not repeated herein.


Illustratively, in the data refresh phase TS of the display frame F2, data voltages input to the sub-pixels in the display panel may be controlled, so that the display panel displays a picture of the display frame F2. Specifically, the scan drive signal ga1 is loaded on the scan signal line GA1, the scan drive signal ga2 is loaded on the scan signal line GA2, and when an active level (e.g., a high level signal in each of the scan drive signals ga1 to ga4) appears in each of the signals ga1 to ga4, the switch transistor 01, which is coupled to a corresponding one of the scan signal lines GA1 to GA4, is controlled to be turned on. For example, when a high level signal appears in the scan drive signal ga1, the switch transistors 01 in the first row of sub-pixels may all be controlled to be turned on. In addition, the data signal line DA1 is loaded with a data voltage da1 corresponding to the negative polarity, the data signal line DA2 is loaded with a data voltage da2 corresponding to the positive polarity, and the data signal line DA3 is loaded with a data voltage da3 corresponding to the negative polarity, so that the data voltages loaded on the data signal lines DA1 to DA3 are input to the pixel electrodes 02 in the first row of sub-pixels, through the turned-on switch transistors 01 in the first row of sub-pixels, so that the corresponding data voltages can be input to the pixel electrodes 02 in the first row of sub-pixels, and further, each sub-pixel in the first row can be input with the data voltage, thereby realizing the charging of each sub-pixel in the first row.


Then, in a blanking time phase TB of the display frame F2, the scan drive signals ga1 to ga4 are all low level signals, the switch transistor 01 in each sub-pixel in the display panel is in a turned-off state, and the pixel electrode 02 in each sub-pixel can be controlled to maintain the data voltage, so that the sub-pixels in the display panel can be controlled to maintain the data voltage, and the display panel can continue to display the picture of the display frame F2.


The implementation of the remaining sub-pixels is similarly performed in sequence until charging the corresponding data voltages is finished throughout the sub-pixels in the whole display panel, which is not repeated herein.


In general, in a display panel such as a Liquid Crystal Display (LCD) panel, an Organic Light Emitting Diode (OLED) display panel, a Quantum Dot Light Emitting Diodes (QLED) display panel, an electronic paper display panel, or the like, power consumption, especially logic drive power consumption, has always been a key consideration in device design. As the resolution and the refresh rate of the display panel continue to increase, the logic drive power consumption also increases. On the other hand, with the increasing demand for low-carbon living, the demand for low power consumption performance of the display panel is also increasing. Therefore, under the condition of satisfying the requirements of people on high image quality of the display panel with high resolution and high refresh rate, the reduction of power consumption is becoming an important subject and a difficult problem of research and development of the display panel.


In the conventional display panel, a picture of each display frame is displayed at a fixed refresh rate, and even if an area, such as upper and lower black areas of a movie, has no display content, the data voltage is normally refreshed at the fixed refresh rate in each display frame. In addition, in an area where text content or an image is still, the data voltage is normally refreshed at the fixed refresh rate for each display frame even though the picture is not changed. These refresh processes are all meaningless refreshes, resulting in wasted logic drive power consumption.


In order to reduce logic drive power consumption, it is possible to independently drive for a black picture area or a still picture area. For example, the black picture area and the still picture area are defined as non-refresh areas, and the remaining areas are defined as refresh areas. The non-refresh area and the refresh area can be independently refreshed, for example, the non-refresh area is not refreshed or is refreshed at a reduced refresh rate, the refresh area is normally refreshed, and a range of the refresh area can be adaptively and dynamically adjusted according to a change of the display content of the picture, so that the logic drive power consumption of the display panel is greatly reduced as far as possible on the premise of not influencing the high-quality display of the picture.


In general, a gate driver circuit coupled to all scan signal lines is provided in the display panel, to output scan drive signals to the coupled gate lines through the gate driver circuit. In addition, the gate driver circuit generally includes a plurality of cascaded shift registers, and the shift registers may operate in sequence, to input scan drive signals to the scan signal lines line by line, so that the scan signal lines can be driven line by line and the data voltages can be refreshed line by line. However, such a gate driver circuit is disadvantageous to realize that the non-refresh area is not refreshed or is refreshed at a reduced refresh rate, and the refresh area is normally refreshed.


For this reason, an embodiment of the present disclosure provides a drive control circuit 200, and the drive control circuit 200 includes a first control circuit 210 and a second control circuit. The first control circuit 210 may acquire image data, so that a first selection command signal can be output according to the acquired image data. In addition, by providing the second control circuit, the second control circuit is coupled to the scan signal lines in the display panel, and the second control circuit is further coupled to the first control circuit 210, so that the second control circuit can receive the first selection command signal output by the first control circuit 210, and thus, according to the received first selection command signal, target scan signal lines, to which scan drive signals are to be input, are determined from the scan signal lines in the display panel, and the scan drive signals are output to the target scan signal lines. Therefore, the display panel can be driven independently in different areas, and the logic drive power consumption of the display panel can be greatly reduced.


Illustratively, the first control circuit may be a timing controller (TCON) or a System On Chip (SOC), or the like, and is not limited herein.


In some embodiments of the present disclosure, as shown in FIG. 1, the drive control circuit 200 may include a first control circuit 210 and at least one second control circuit 220. All the second control circuits are coupled to the first control circuit 210, each of the second control circuits is coupled to at least one scan signal line, and different second control circuits are coupled to different scan signal lines. Moreover, the first control circuit 210 may be configured to acquire image data and output a first selection command signal according to the image data. In addition, the at least one second control circuit is configured to receive the first selection command signal, determine, according to the first selection command signal, target scan signal lines from among the scan signal lines in the display panel, and output scan drive signals to the target scan signal lines. Therefore, an area where the determined target scan signal lines are located in the display panel can serve as an area to be independently driven, so that independent driving is realized, and the logic drive power consumption of the display panel can be greatly reduced.


In some embodiments of the present disclosure, the present disclosure does not limit the number of the second control circuits. For example, one, two, three, four, six, eight, or more second control circuits may be provided. Moreover, the scan signal lines coupled to different second control circuits are different. A plurality of scan signal lines may be coupled to one second control circuit, or one scan signal line may be coupled to one second control circuit. In practical applications, the number of the second control circuits may be set according to the number of the scan signal lines in the display panel.


In some embodiments of the present disclosure, a plurality of scan signal lines provided in a display panel are divided into at least one scan signal line group, each including at least one scan signal line. Moreover, the second control circuits are arranged in one-to-one correspondence with the scan signal line groups. Illustratively, the plurality of scan signal lines provided in the display panel are divided into one scan signal line group, and one second control circuit may be provided in the drive control circuit, so that the second control circuit determines, according to the received first selection command signal, target scan signal lines from among the plurality of scan signal lines, that is, determines scan signal lines that need to be independently driven, and inputs scan drive signals to these determined scan signal lines, to drive these determined target scan signal lines in one display frame without driving the scan signal lines other than the target scan signal lines. Alternatively, two second control circuits may be provided, and the two second control circuits each are coupled to the scan signal line group, and each may be configured to determine, according to the received first selection command signal, target scan signal lines from among the plurality of scan signal lines, that is, to determine scan signal lines that need to be independently driven, and input scan drive signals to these determined scan signal lines, to drive these determined target scan signal lines in one display frame without driving the scan signal lines other than the target scan signal lines.


In some embodiments of the present disclosure, as shown in FIG. 4, optionally, the plurality of scan signal lines arranged in the display panel are divided into two scan signal line groups, where the two scan signal line groups are a first scan signal line group GAZ1 and a second scan signal line group GAZ2, respectively. Moreover, the first scan signal line group GAZ1 is provided with a second control circuit, and the second scan signal line group GAZ2 is provided with a second control circuit. Illustratively, the first scan signal line group GAZ1 may be provided with two second control circuits, which are a first second control circuit 220-1a and a second second control circuit 220-1b, respectively.

Then, the first control circuit 210 may compare the image data of the consecutive display frames, to determine whether set picture data in a same first image area in image data of at least two adjacent display frames exists in the consecutive display frames. When it is determined that the consecutive display frames includes at least two adjacent display frames, the image data of which each has the set picture data in the same first image area, it is possible to determine an area outside the first image area as a second image area TX2, determine scan signal lines coupled to the pixel units in the first image area as target scan signal lines, and output a first selection command signal according to the determined scan signal lines, in each of the at least two adjacent display frames. This makes it possible for the second control circuit to output the scan drive signals to the scan signal lines in the first image area, so that it is possible to drive only the scan signal lines in the first image area, without driving the scan signal lines in the second image area TX2. Thus, independently driving the first image area can be realized, and the logic drive power consumption can be reduced.

Thereafter, the first control circuit 210 may compare the image data of the consecutive display frames, to determine whether set picture data in a same first image area in image data of at least two adjacent display frames exists in the consecutive display frames. When it is determined that the consecutive display frames includes at least two adjacent display frames, the image data of which each has the set picture data in the same first image area, it is possible to determine an area outside the first image area as the second image area TX2, determine the scan signal lines coupled to the pixel units in the second image area TX2 as target scan signal lines, and output the first selection command signal according to the determined scan signal lines, in each of the at least two adjacent display frames. This makes it possible for the second control circuit to output the scan drive signals to the scan signal lines in the second image area TX2, so that it is possible to drive only the scan signal lines in the second image area TX2, without driving the scan signal lines in the first image area.

The at least one first image area and the at least one second image area TX2 are alternately arranged. Alternatively, as shown in FIG. 5, two first image areas are provided, which are a first first image area TX1-1 and a second first image area TX1-2, respectively. One second image area TX2 is provided, that is the second image area TX2. In addition, the second image area TX2 is arranged between the first first image area TX1-1 and the second first image area TX1-2.

In general, in a display panel, electrons flow to generate a current, the current passes through elements such as a signal line, a transistor, and the like, and the element itself has a resistance, and electric charges may be consumed through a resistance heating effect. An expression for power consumption P is:

    • where u(t) represents a voltage at time t during the T time period, and i(t) represents a current at time t during the T time period. Therefore, according to the above formula, the power consumption is an integral of a product of the voltage and the current per unit time. For a square wave pulse signal, under a certain period, the higher the voltage jump amplitude and the current are, the higher the power consumption is. In a case where the product of voltage and current is constant, the shorter the period is, that is, the higher the frequency is, the higher the power consumption is.





An expression for the current is:

    • where C represents a parasitic capacitance of the signal line. As can be seen from the above formula, in a case where the voltage jump amplitude is constant, the higher the parasitic capacitance of the signal line is, the higher the generated current is.





Therefore, reducing the number of signal outputs (no refresh) and reducing a refresh rate of the signal are straightforward and effective ways to reduce the logic drive power consumption.

Embodiments of the present disclosure provide other implementations of the drive control circuit, which are modified from the implementations in the above embodiments. Only the differences between the present embodiment and the above embodiments will be described below, and the same parts will not be repeated herein.


If the first image area is a still picture or a dynamic picture with a slow motion, but with a brightness, the first image area is refreshed with a lower refresh rate. In some embodiments of the present disclosure, the first control circuit is further configured to determine a refresh rate corresponding to the first image area as a first refresh rate, and determine a refresh rate corresponding to the second image area as a second refresh rate, where the first refresh rate is less than the second refresh rate. Illustratively, the second refresh rate f2 may be an integer multiple of the first refresh rate f1. That is, f2=a×f1, where a is an integer greater than 1.


Illustratively, in a plurality of consecutive display frames, a data refresh process for the first image area may be performed in one display frame, and a data refresh process for the second image area may be performed in the next multiple display frames. Then, the data refresh process for the first image area is performed in one display frame, and so on. Therefore, the logic drive power consumption is reduced. Specifically, in this driving manner, when refreshed at a lower refresh rate, the blanking time phase is longer in the corresponding data voltage, and when refreshed at a higher refresh rate, the blanking time phase is shorter in the corresponding data voltage. The power consumption on the scan side and the data side can be simultaneously reduced by adopting this driving manner, and are each reduced by

The second shift register sub-unit SGOA is coupled to the plurality of second clock control signal sub-lines, and the second shift registers in the second shift register sub-unit SGOA are coupled to the second clock control signal sub-lines in one-to-one correspondence, so that each second shift register is coupled to one second clock control signal sub-line.

Next, an operation process of the drive control circuit 200 provided by the embodiment of the present disclosure is described with reference to FIGS. 13, 14a, and 20, taking first to tenth display frames as an example.


The first control circuit 210 may acquire image data of the first to tenth display frames, and compare the image data of the first to tenth display frames to determine whether black picture data in a same first image area exists in the first to tenth display frames. When it is determined that the black picture data in the first first image area TX1-1 and the second first image area TX1-2 exists in the first to tenth display frames, during each of the first to tenth display frames, the scan signal lines coupled to the pixel units in the second image area TX2 are determined as target scan signal lines. Moreover, a first selection command signal CX2 is output during each of the first to tenth display frames.


During the first display frame, as shown in FIG. 14a, the first control circuit 210 outputs a first selection command signal CX2, and the first selection command signal CX2 includes address information of 000, 001, 010, and 011, and may include data selected information of 0010 to 0111.


In addition, the first control circuit 210 further outputs a first image enable signal to the source driver circuit, and controls the first zero gray scale output buffer and the second zero gray scale output buffer not to operate, and controls the non-zero gray scale output buffers to operate. The source driver circuit controls each control switch to turn it conductive between the first input terminal and the output terminal of the control switch, thereby may perform a series of processing on the image data in the second image area TX2 according to the received image data in the second image area TX2, and then input the processed image data into the coupled non-zero gray scale output buffers, to apply the corresponding data voltages to the data signal lines in the second image area TX2 through the non-zero gray scale output buffers.


The frame start signal control circuit 221-1b of the second second control circuit 220-1b may determine, according to the address information: 010 and the data selected information: 0010 to 0111 in the first selection command signal CX2, the third to fifth scan signal lines GA3 to GA5 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate a first target frame start signal stv3b to be input to the input signal terminal INP of the first shift register PSR1. Moreover, the generated first target frame start signal stv3b is input to the input signal terminal INP of the first shift register PSR1. The first control circuit 210 further inputs the corresponding reference clock control signals cks1 to cks12 to the level shift circuit 240, and the level shift circuit 240 generates clock signals respectively input to the first clock control signal sub-line PCK1 and the first clock control signal sub-line PCK2, and generates clock signals respectively input to the second clock control signal sub-line SCK3 to the second clock control signal sub-line SCK5, according to the received reference clock control signal corresponding to the first shift register PSR1 and the first reference voltage VREF1 and the second reference voltage VREF2. Thus, the cascade signal output terminals of the first shift registers PSR1 to PSR4 may output cascade signals P1 to P4, respectively. The cascade signal P1 is input into the input signal terminal INP of the second shift register SSR1, but no clock signal is input to the second clock control signal sub-line SCK1 coupled to the second shift register SSR1, so that the drive signal output terminal GO of the second shift register SSR1 does not output a signal. Similarly, the cascade signal P2 is input to the input signal terminal INP of the second shift register SSR2, but no clock signal is input to the second clock control signal sub-line SCK2 coupled to the second shift register SSR2, so that the drive signal output terminal GO of the second shift register SSR2 does not output a signal. However, the cascade signal P3 is input to the input signal terminal INP of the second shift register SSR3, and a corresponding clock signal is input to the second clock control signal sub-line SCK3 coupled to the second shift register SSR3, so that the drive signal output terminal GO of the second shift register SSR3 outputs a scan drive signal gb3. Similarly, the cascade signal P4 is input into the input signal terminal INP of the second shift register SSR4, and a corresponding clock signal is input to the second clock control signal sub-line SCK4 coupled to the second shift register SSR4, so that the drive signal output terminal GO of the second shift register SSR4 outputs a scan drive signal gb4. The cascade signal P5 is input to the input signal terminal INP of the second shift register SSR5, and a corresponding clock signal is input to the second clock control signal sub-line SCK5 coupled to the second shift register SSR5, so that the drive signal output terminal GO of the second shift register SSR5 outputs a scan drive signal gb5.


It should be noted that, operation processes of the remaining second control circuits may be analogized in sequence, and are not repeated herein.

Alternatively, the display panel includes dual trigger signals, for example, the first and second rows correspond to different initial trigger signals STV′, respectively. That is, transfer of the cascade signals of the entire display panel is triggered by the initial trigger signals input to the first and second rows. The initial trigger signal STV′ is input to the input signal terminal INP of the first shift register PSR1, the first shift register sub-unit PGOA serves to output the cascade signals, and the first clock control signal sub-lines (e.g., PCK1 and PCK2) control the first shift register sub-unit PGOA to output the cascade signals line by line. Whether any row in the display panel is turned-on or not is realized by adjusting clock signals (e.g., SCK1, SCK2, SCK3, etc.) provided by the plurality of second clock control signal sub-lines. If a certain row is required to be turned-on, the second clock control signal sub-line correspondingly connected to this certain row is given an active level at the corresponding time, so that the scan line at this certain row is turned-on; if a certain row is required to be turned-off, the second clock control signal sub-line correspondingly connected to this certain row is given an inactive level at the corresponding time, so that the scan line at this certain row is turned-off. That is, any row is turned-on by adjusting the clock signals provided by the plurality of second clock control signal sub-lines (e.g. SCK1 to SCK3, and the like), while the cascade signals of the display panel are still output in cascade line by line, according to the full-scan mode of the display panel (scan from a first row of the display panel to a last row of the display panel).


Next, an operation process of the drive control circuit provided by the embodiment of the present disclosure is described with reference to FIGS. 13, 14a, and 21, taking first to tenth display frames as an example.


The first control circuit 210 may acquire image data of the first to tenth display frames, and compare the image data of the first to tenth display frames to determine whether black picture data in a same first image area exists in the first to tenth display frames. When it is determined that the black picture data in the first first image area TX1-1 and the second first image area TX1-2 exists in the first to tenth display frames, during each of the first to tenth display frames, the scan signal lines coupled to the pixel units in the second image area TX2 are determined as target scan signal lines. Moreover, a first selection command signal CX2 is output during each of the first to tenth display frames.


During the first display frame, as shown in FIG. 14a, the first control circuit 210 outputs a first target frame start signal to the input signal terminal INP of the third shift register PZR1. The first control circuit 210 further outputs a first image enable signal to the source driver circuit, and controls the first zero gray scale output buffer and the second zero gray scale output buffer not to operate, and controls the non-zero gray scale output buffers to operate. The source driver circuit controls each control switch to turn it conductive between the first input terminal and the output terminal of the control switch, thereby may perform a series of processing on the image data in the second image area TX2 according to the received image data in the second image area TX2, and then input the processed image data into the coupled non-zero gray scale output buffers, to apply the corresponding data voltages to the data signal lines in the second image area TX2 through the non-zero gray scale output buffers.


The first control circuit 210 further inputs corresponding reference clock control signals to the level shift circuit 240, and the level shift circuit 240 generates clock signals respectively input to the third clock control signal sub-line PZK1 and the third clock control signal sub-line PZK2, and generates clock signals respectively input to the fourth clock control signal sub-line SZK3 to the second clock control signal sub-line SZK8, according to the received reference clock control signal corresponding to the third shift register, and the first reference voltage VREF1 and the second reference voltage VREF2. Thus, the cascade signal output terminals of the third shift registers PZR1 to PZR8 may output cascade signals J1 to J8, respectively. The cascade signal J1 is input to the input signal terminal INP of the fourth shift register SZR1, but no clock signal is input to the fourth clock control signal sub-line SZK1 coupled to the fourth shift register SZR1, so that the drive signal output terminal GO of the fourth shift register SZR1 does not output a signal. Similarly, the cascade signal J2 is input to the input signal terminal INP of the fourth shift register SZR2, but no clock signal is input to the third clock control signal sub-line SZK2 coupled to the fourth shift register SZR2, so that the drive signal output terminal GO of the fourth shift register SZR2 does not output a signal. However, the cascade signal J3 is input to the input signal terminal INP of the fourth shift register SZR3, and a corresponding clock signal is input to the fourth clock control signal sub-line SZK3 coupled to the fourth shift register SZR3, so that the drive signal output terminal GO of the fourth shift register SZR3 outputs a scan drive signal ga3. Similarly, the cascade signal J4 is input to the input signal terminal INP of the fourth shift register SZR4, and a corresponding clock signal is input to the fourth clock control signal sub-line SZK4 coupled to the fourth shift register SZR4, so that the drive signal output terminal GO of the fourth shift register SZR4 outputs a scan drive signal ga4.


It should be noted that, through adjusting, by the first control circuit 210, the first target frame start signal input to the first gate scan sub-circuit as described above, the scan signal lines in different areas can be individually driven.

Illustratively, taking it as an example that, during a display frame, the first control circuit 210 outputs a first selection command signal CX1, and the first selection command signal CX1 includes address information of 000, 001, 010, and 011, and may include data selected information of 0000 to 0001, and 1000 to 1001, the second decoder 2221 receives the first selection command signal CX1, and may determine, according to the address information: 000 and the data selected information: 0000 to 0001 in the first selection command signal CX1, the first scan signal line GA1 and the second scan signal line GA2 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate scan generating signals corresponding to the first scan signal line GA1 and the second scan signal line GA2. The second frame start signal generator 2222 receives the scan generating signals corresponding to the first scan line GA1 and the second scan line GA2, and generates the corresponding initial scan signals according to the received scan generating signals corresponding to the first scan line GA1 and the second scan line GA2. Moreover, the generated initial scan signals are sent to the second level shifter 2223, and the second level shifter 2223 performs voltage shift processing on the received initial scan signal corresponding to the first scan signal line GA1 to generate a scan drive signal ga1, and performs voltage shift processing on the received initial scan signal corresponding to the second scan signal line GA2 to generate a scan drive signal ga2. Moreover, the scan drive signal ga1 is input to the first scan signal line GA1, and the scan drive signal ga2 is input to the second scan signal line GA2. It should be noted that, an operation process of the first control circuit 210 when outputting the first selection command signal CX2 may be analogized, and the details thereof are not described herein.


Next, an operation process of the foregoing drive control circuit provided by the embodiment of the present disclosure is described with reference to FIGS. 13, 14a, 14b, and 22 to 23, taking consecutive first to tenth display frames as an example.


The first control circuit 210 may acquire image data of the first to tenth display frames, and compare the image data of the first to tenth display frames to determine whether set picture data in a same first image area exists in the first to tenth display frames. When it is determined that the black picture data in the first first image area TX1-1 and the second first image area TX1-2 exists in the first to tenth display frames, during each of the first and sixth display frames, the scan signal lines coupled to the pixel units in the first first image area TX1-1 and the second first image area TX1-2 are determined as target scan signal lines, and during each of the second to fifth display frames and the seventh to tenth display frames, the scan signal lines coupled to the pixel units in the second image area TX2 are determined as target scan signal lines. In addition, a first selection command signal CX1 is output during each of the first display frame and the sixth display frame, and a first selection command signal CX2 is output during each of the second to fifth display frames and the seventh to tenth display frames.


During the first display frame, as shown in FIG. 14b, the first control circuit 210 outputs a first select command signal CX1, and the first select command signal CX1 includes address information of 000, 001, 010, and 011, and may include data selected information of 0000 to 0001 and 1000 to 1001.


In addition, the first control circuit 210 further outputs a first image disable signal to the source driver circuit, controls the first zero gray scale output buffer and the second zero gray scale output buffer to operate, and controls the non-zero gray scale output buffer not to operate. The data conversion circuit may perform a series of processing on the image data (i.e., 0 gray scale) in the first image area according to the received image data in the first image area, and then input the image data into the coupled first and second zero gray scale output buffers. Each control switch is controlled to turn it conductive between the second input terminal and the output terminal thereof, so that the data voltages corresponding to the negative polarity are applied to the data signal lines in the first image area through the first zero gray scale output buffer. Moreover, each control switch is controlled to turn it conductive between the third input terminal and the output terminal thereof, so that the data voltages corresponding to the positive polarity are applied to the data signal lines in the first image area through the second zero gray scale output buffer.


The second decoder 2221 of the scan control output circuit 222-1a in the first second control circuits 220-1a may determine, according to the address information: 000 and the data selected information: 0000 to 0001 in the first selection command signal CX1, the first scan signal line GA1 and the second scan signal line GA2 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate scan generating signals corresponding to the first scan signal line GA1 and the second scan signal line GA2. The second frame start signal generator 2222 generates initial scan signals corresponding to the first scan signal line GA1 and the second scan signal line GA2, according to the scan generating signals corresponding to the first scan signal line GA1 and the second scan signal line GA2. The second level shifter 2223 performs voltage shift processing on the initial scan signals corresponding to the first scan signal line GA1 and the second scan signal line GA2, generates scan drive signals corresponding to the first scan signal line GA1 and the second scan signal line GA2, and inputs the scan drive signals to the corresponding scan signal lines.


In addition, the second decoder 2221 of the scan control output circuit 222-1b in the second second control circuit 220-1b may determine, according to the address information: 001 and the data selected information: 0000 to 0001 in the first selection command signal CX1, the first scan signal line GA1 and the second scan signal line GA2 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate scan generating signals corresponding to the first scan signal line GA1 and the second scan signal line GA2. The second frame start signal generator 2222 generates initial scan signals corresponding to the first scan signal line GA1 and the second scan signal line GA2, according to the scan generating signals corresponding to the first scan signal line GA1 and the second scan signal line GA2. The second level shifter 2223 performs voltage shift processing on the initial scan signals corresponding to the first scan signal line GA1 and the second scan signal line GA2, generates scan drive signals corresponding to the first scan signal line GA1 and the second scan signal line GA2, and inputs the scan drive signals to the corresponding scan signal lines.


Thus, when a high level signal appears in each of the scan drive signals input to the first scan signal line GA1 and the second scan signal line GA2, the data voltages with corresponding polarities output from the data signal lines may be input to the pixel electrodes of the sub-pixels, to realize charging the sub-pixels in the first first image area TX1-1.


In addition, the second decoder 2221 of the scan control output circuit 222-2a in the third second control circuit 220-2a may determine, according to the address information: 010 and the data selected information: 1000 to 1001 in the first selection command signal CX1, the ninth scan signal line GA9 and the tenth scan signal line GA10 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate scan generating signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10. The second frame start signal generator 2222 generates initial scan signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10, according to the scan generating signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10. The second level shifter 2223 performs voltage shift processing on the initial scan signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10, generates scan drive signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10, and inputs the scan drive signals to the corresponding scan signal lines.


In addition, the second decoder 2221 of the scan control output circuit 222-2b in the fourth second control circuit 220-2b may determine, according to the address information: 011 and the data selected information: 1000 to 1001 in the first selection command signal CX1, the ninth scan signal line GA9 and the tenth scan signal line GA10 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate scan generating signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10. The second frame start signal generator 2222 generates initial scan signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10, according to the scan generating signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10. The second level shifter 2223 performs voltage shift processing on the initial scan signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10, generates scan drive signals corresponding to the ninth scan signal line GA9 and the tenth scan signal line GA10, and inputs the scan drive signals to the corresponding scan signal lines.


Thus, when a high level signal appears in each of the scan drive signals input to the ninth scan signal line GA9 and the tenth scan signal line GA10, the data voltages with corresponding polarities output to the data signal lines may be input to the pixel electrodes of the sub-pixels, to realize charging the sub-pixels in the second first image area TX1-2.


During the second display frame, referring to FIG. 14a, the first control circuit 210 outputs a first selection command signal CX2, and the first selection command signal CX2 includes address information of 000, 001, 010, and 011, and may include data selected information of 0010 to 0111.


Moreover, the first control circuit 210 further outputs a first image enable signal to the source driver circuit, and controls the first zero gray scale output buffer and the second zero gray scale output buffer not to operate, and controls the non-zero gray scale output buffers to operate. The source driver circuit controls each control switch to turn it conductive between the first input terminal and the output terminal of the control switch, thereby may perform a series of processing on the image data in the second image area TX2 according to the received image data in the second image area TX2, and then input the processed image data into the coupled non-zero gray scale output buffers, to apply the corresponding data voltages to the data signal lines in the second image area TX2 through the non-zero gray scale output buffers.


The second decoder 2221 of the scan control output circuit 222-1a in the first second control circuits 220-1a may determine, according to the address information: 000 and the data selected information: 0010 to 0111 in the first selection command signal CX2, the third to fifth scan signal lines GA3 to GA5 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate scan generating signals corresponding to the third to fifth scan signal lines GA3 to GA5. The second frame start signal generator 2222 generates initial scan signals corresponding to the third to fifth scan lines GA3 to GA5 according to the scan generating signals corresponding to the third to fifth scan lines GA3 to GA5. The second level shifter 2223 performs voltage shift processing on the initial scan signals corresponding to the third to fifth scan signal lines GA3 to GA5, generates scan drive signals corresponding to the third to fifth scan signal lines GA3 to GA5, and inputs the scan drive signals to the corresponding scan signal lines.


In addition, the second decoder 2221 of the scan control output circuit 222-1b in the second second control circuit 220-1b may determine, according to the address information: 001 and the data selected information: 0010 to 0111 in the first selection command signal CX2, the third to fifth scan signal lines GA3 to GA5 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate scan generating signals corresponding to the third to fifth scan signal lines GA3 to GA5. The second frame start signal generator 2222 generates initial scan signals corresponding to the third to fifth scan lines GA3 to GA5 according to the scan generating signals corresponding to the third to fifth scan lines GA3 to GA5. The second level shifter 2223 performs voltage shift processing on the initial scan signals corresponding to the third to fifth scan signal lines GA3 to GA5, generates scan drive signals corresponding to the third to fifth scan signal lines GA3 to GA5, and inputs the scan drive signals to the corresponding scan signal lines.


In addition, the second decoder 2221 of the scan control output circuit 222-2a in the third second control circuit 220-2a may determine, according to the address information: 010 and the data selected information: 0010 to 0111 in the first selection command signal CX2, the sixth to eighth scan signal lines GA6 to GA8 from among the correspondingly coupled scan signal lines, as target scan signal lines, and generate scan generating signals corresponding to the sixth to eighth scan signal lines GA6 to GA8. The second frame start signal generator 2222 generates initial scan signals corresponding to the sixth to eighth scan lines GA6 to GA8 according to the scan generating signals corresponding to the sixth to eighth scan lines GA6 to GA8.

Thus, when a high level signal appears in each of the scan drive signals input to the third to eighth scan signal lines GA3 to GA8, data voltages with corresponding polarities output to the data signal lines may be input to the pixel electrodes of the sub-pixels, to realize charging the sub-pixels in the second image area TX2.


During each of the third to fifth display frames, an operation process thereof may refer to the operation process of the second display frame, which is not repeated herein.


During the sixth display frame, an operation process thereof may refer to the operation process of the first display frame, which is not repeated herein.


During each of the seventh to tenth display frames, an operation process of the display frame may refer to the operation process of the second display frame, which is not repeated herein.


Compared with the conventional GATE IC in the prior art, the scan control output circuit can start outputting the scan drive signal from any one row of scan signal lines, and end the outputting at any one row of scan signal lines. Therefore, in the embodiment of the present disclosure, the first control circuit is required to send an instruction for controlling the start and end of outputting the scan drive signal by the scan control output circuit. Therefore, the scan control output circuit in the embodiment of the present disclosure is required to have a communication interface such as I2C (Inter-Integrated Circuit), and have a decoder with a command decoding function. The conventional Gate IC in the prior art does not have a communication interface and a decoder with decoding function, and the conventional Gate IC starts scanning line by line, from the first line to the last line, only after receiving a frame start signal sent by the TCON/SOC.


It should be noted that, in the embodiment of the present disclosure, the scan signal line required to be scanned is determined as the target scan signal line, so that the scan signal line required to be scanned is turned on. Moreover, no scan drive signals are input to the rest scan signal lines which are not determined as the target scan signal lines, so that the scan signal lines which are not required to be scanned are turned-off. For these scan signal lines that are not required to be scanned, the implementation of their corresponding data voltages may include the following methods.


A first method: for the scan signal lines that are not required to be scanned, the data voltages corresponding to the scan signal lines may be normally input to the corresponding data lines. However, since the scan signal lines are not turned on, the data voltages are not input to the corresponding sub-pixels (e.g., the black picture area).


A second method: for the scan signal lines that are not required to be scanned, the source driver circuit does not directly output the data voltages corresponding to the scan signal lines. That is, the data voltage is not input to the data signal line at the moment.


In the second method: for the scan signal lines that are not required to be scanned, the source driver circuit shown in FIG. 12 may be adopted to output the data voltages corresponding to the scan signal lines.


Based on the same disclosure concept, an embodiment of the present disclosure further provides a display apparatus, which includes the foregoing display panel provided by the embodiment of the present disclosure and the foregoing drive control circuit provided by the embodiment of the present disclosure.
