In some embodiments of the present disclosure, as shown in
In some embodiments of the present disclosure, as shown in
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
Illustratively, as shown in
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
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.

Illustratively, the second scan signal line group GAZ2 may be provided with two second control circuits, which are a third second control circuit 220-2a and a fourth second control circuit 220-2b, respectively. The scan signal lines each have first and second ends opposite to each other in an extending direction thereof. The third second control circuit 220-2a is coupled to the scan signal lines in the second scan signal line group GAZ2, for example, the third second control circuit 220-2a is coupled to first ends (e.g., left ends) of the scan signal lines in the second scan signal line group GAZ2. The fourth second control circuit 220-2b is also coupled to the scan signal lines in the second scan signal line group GAZ2, for example, the fourth second control circuit 220-2b is coupled to second ends (e.g., right ends) of the scan signal lines in the second scan signal line group GAZ2.

Moreover, scan-off signals (e.g., low level signals) are input to the third to fifth scan signal lines GA3 to GA5.
Illustratively, when the first selection command signal includes address information of 010 and 011 and the data selected information may be 1000 to 1001, the third second control circuit 220-2a may determine, according to the data selected information: 1000 to 1001 in the first selection command signal, the ninth scan signal line GA9 and the tenth scan signal line GA10 from among the scan signal lines in the display panel, as target scan signal lines, so that the scan drive signals are input to only the ninth scan signal line GA9 and the tenth scan signal line GA10.

In some embodiments of the present disclosure, the first control circuit 210 may be further configured to acquire image data corresponding to a plurality of consecutive display frames. That is, image data corresponding to each of two or more consecutive display frames may be acquired. 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.
In some embodiments, the set picture data may be a black picture data, and the first image area may be a black picture area. Illustratively, the black picture data may be set to display data corresponding to 0 gray scale.
In other embodiments, the set picture data may be still/static picture data, and the second image area TX2 may be a still/static picture area.
In some embodiments of the present disclosure, the first control circuit 210 may be further configured to acquire image data corresponding to a plurality of consecutive display frames. That is, image data corresponding to each of two or more consecutive display frames may be acquired. 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. Thus, independently driving the first image area can be realized, and the logic drive power consumption can be reduced.
In some embodiments of the present disclosure, the first image area may include a plurality of adjacent pixel unit rows, and the second image area TX2 may also include a plurality of adjacent pixel unit rows. Moreover, the first image area includes different pixel unit rows from the second image area TX2. Moreover, the number of pixel unit rows in the first image area may be the same as or different from the number of pixel unit rows in the second image area TX2. Illustratively, at least one first image area may be set, and at least one second image area TX2 may also be set.

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.

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 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
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.

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
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, 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.

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.

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.

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
