This application claims priority to Chinese patent application No. 202011595193.1 filed with CNIPA on Dec. 29, 2020, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of display panels and, in particular, a display panel, a display device, and a driving method of a display panel.
An electroluminescent display is a kind of self-luminescent device, which can achieve a display function without setting a backlight module, so this kind of display has been widely applied in various fields because of its characteristics such as being light in weight, and thin in shape.
Under the background of narrow step demand for wearable products, a multiplexer is usually provided in the product, and the multiplexer needs to select mux 1:12 or more to reduce the number of signal traces in a total fan-out region of the display panel. At this time, the increase in the number of outputs in the multiplexer reduces the time of scanning a gate signal, resulting in the display panel being prone to having vertical stripes when displaying the picture, thus reducing the display effect. Based on this, how to improve the display effect of the high-frequency electroluminescent display needs to be solved urgently.
Embodiments of the present disclosure provide a display panel, a display device, and a driving method of the display panel to improve the display effect of the high-frequency electroluminescent display.
In an embodiment, the present disclosure provides a display panel including a display region and a non-display region, the display region includes pixel units arranged in an array, and each of the pixel units includes sub-pixels having multiple colors.
Each of the sub-pixels includes a pixel circuit and a light-emitting element, and the pixel circuit in each of the sub-pixels includes a data write module, a light emission control module and a drive transistor. The non-display region includes a multiplexer, the multiplexer includes multiple data selection units; each of the multiple data selection units includes one input terminal and multiple output terminals, and the multiple output terminals of each data selection unit are electrically connected to multiple data lines of the display region in one-to-one correspondence.
In the same row of pixel units, first control terminals of data write modules of sub-pixels having a first color are connected to the same first scanning line; and in the same row of pixel units, first control terminals of data write modules of sub-pixels having other colors except the first color are connected to the same second scanning line.
The data write module is configured to provide a data signal cached by a data line to the drive transistor; and the light emission control module is connected in series respectively with the drive transistor and the light-emitting element, and the light emission control module is configured to control whether a drive current flows through the light-emitting element.
In the same row of the pixel units, within time of one frame of a picture, time of providing data signals for data lines connected to the sub-pixels having the first color is within time of writing data signals cached by data lines into pixel circuits of the sub-pixels having the other colors.
In an embodiment, the present disclosure further provides a display device including the display panel described in the above-mentioned embodiment.
In a third aspect, an embodiment of the present disclosure further provides a driving method of a display panel. The driving method is applied to the display panel described in the above-mentioned embodiment. A drive cycle of the display panel includes a data cache stage, a data write stage and a light emission stage. The driving method includes steps described below.
In the data cache stage, the multiplexer transmits the data signals to the multiple data lines to perform caching.
In the data write stage, data write modules provide the data signals cached by the multiple data lines for drive transistors.
In the light emission stage, the light emission control module controls the drive current to flow through the light-emitting element.
In the same row of pixel units, within the time of one frame of the picture, the time of providing the data signals for the data lines connected to the sub-pixels having the first color is within the time of writing the data signals cached by the data lines into pixel circuits of the sub-pixels having the other colors.
In the display panel, the display device and the driving method of the display panel provided in the embodiments of the present disclosure, according to the influences of sub-pixels having different colors on the display screen of the display panel, sub-pixels having a smaller influence on the display screen of the display panel are selected as the sub-pixels having the first color, and sub-pixels having a greater influence on the display screen of the display panel are selected as the sub-pixels having the other colors within the time of one frame of the picture. The time of providing the data signals for the data lines connected to the sub-pixels having the first color which have the smaller influence on the display screen of the display panel is set to be within the time of writing the data signals cached by the data lines into the pixel circuits of the sub-pixels having the other colors, that is, the display panel first provides the data signals for the data lines connected to the sub-pixels having the other colors; after the data signals are provided for the data lines connected to the sub-pixels having the other colors, the data signals are provided for the data lines connected to the sub-pixels having the first color. Since the sub-pixels having the other colors have completed providing the data signals for the corresponding connected data lines, providing the data signals for the data lines connected to the sub-pixels having the first color is simultaneous with outputting control signals to first control terminals of the data write modules corresponding to the sub-pixels having the other colors through the second scanning lines, so as to control the data write modules corresponding to the sub-pixels having the other colors to be turned on, it can be achieved that the data write modules in the pixel circuits corresponding to the sub-pixels having the other colors provide the data signals cached by the data lines for the drive transistors. Since the time of writing the data signals cached by the data lines of the sub-pixels having the other colors into the drive transistors is increased, ensuring the data writing time corresponding to the sub-pixels having the other colors which have the greater influence on the display effect of the display panel, increasing the charging time of the driving transistors in the pixel circuits corresponding to the sub-pixels having the other colors, and ensuring the display effect of the display panel.
Hereinafter the present disclosure will be further described in detail in conjunction with drawings and embodiments. It is to be understood that the embodiments set forth herein are intended to explain the present disclosure and not to limit the present disclosure. Additionally, it is to be noted that for ease of description, merely part, not all, of the structures related to the present disclosure are illustrated in the drawings.
The inventor finds in research that for a display without a multiplexer (for example, a demux) such as a display using a high-frequency (hipin) design, time corresponding to a conventional product (such as a product having a scanning frequency of 60 Hz) for displaying one frame is generally 16.67 ms. If this kind of product has the resolution of 1080*2340, the time of scanning 2340 rows of pixels is 16.67 ms, that is, the time of scanning one row of pixels is 7.1 μs. However, in a practical scanning process, factors such as time intervals between gate scanning signals input by adjacent gate lines need to be considered, therefore, the time of scanning one row of pixels is generally less than 5 μs in practice.
Similarly, for high-frequency products using the high-frequency design (such as products having a scanning frequency of 120 Hz), due to the increase of the scanning frequency, if time corresponding to displaying one frame of a picture remains unchanged, the time of scanning one row of pixels is reduced by at least half compared with that of low-frequency products, so the charging time of the gate scanning signal of high-frequency products is insufficient, which results in the display panel being prone to having vertical stripes when displaying the picture, thus reducing the display effect.
For high-frequency products providing with the multiplexer (such as the demux), if the gate scanning signal is input to a gate line, it is necessary that inputting the gate scanning signal to the gate line starts after the control line corresponding to a pixel row corresponding to the gate line finishes outputting the control signal. So that the charging time of the gate scanning signal is reduced to less than 0.5 μs within time of scanning one row of pixels, resulting in a serious shortage of the charging time of the gate scanning signal.
For displays (such as 4K or 8K displays) having large-size and high-resolution, with the further increase of the number of scanning rows, the time of scanning one row is further reduced, and accordingly, the charging time of the gate scanning signal becomes even less within the time of scanning one row of pixels, resulting in a serious influence on the display effect.

Light emissions by sub-pixels 11 having different colors have different influences on the display effect of the display panel within the time of one frame of the picture. In the present application, the first control terminals P1A of the data write modules 21A of the sub-pixels 110 having the first color which have the smaller influence on the display effect of the display panel are set to be connected to the same first scanning line Scan1, and the first control terminals P1B of the data write modules 21B of the sub-pixels 111 having the other colors except the sub-pixels having the first color are connected to the same second scanning line Scan2.

In the display panel provided in the embodiments of the present disclosure, according to the influence of sub-pixels having different colors on the display screen of the display panel, the sub-pixels having the smaller influence on the display screen of the display panel are selected as the sub-pixels having the first color, and the sub-pixels having greater influences on the display screen of the display panel are selected as the sub-pixels having the other colors within the time of one frame of the picture. The time of providing the data signals for the data lines connected to the sub-pixels having the first color having the smaller influence on the display screen of the display panel is within the time of writing the data signals cached by the data lines into the pixel circuits of the sub-pixels having the other colors, that is, the display panel first provides the data signals for the data lines connected to the sub-pixels having the other colors, and after providing the data signals for the data lines connected to the sub-pixels having the other colors is completed, the data signals are provided for the data lines connected to the sub-pixels having the first color. Since the sub-pixels having the other colors have completed providing the data signals for the data lines corresponding connected to the sub-pixels having the other colors, providing the data signals for the data lines connected to the sub-pixels having the first color can be simultaneous with outputting control signals to first control terminals of the data write modules corresponding to the sub-pixels having the other colors through the second scanning lines to control the data write modules corresponding to the sub-pixels having the other colors to be turned on, so as to achieve providing the data signals cached by the data lines for the drive transistors by the data write modules in the pixel circuits corresponding to the sub-pixels having the other colors. Since the time of writing the data signals cached by the data lines of the sub-pixels having the other colors into the drive transistors is increased, the data writing time corresponding to the sub-pixels having the other colors which have the greater influence on the display effect of the display panel is ensured, charging time of the driving transistors in the pixel circuits corresponding to the sub-pixels having the other colors is increased, and the display effect of the display panel is ensured.

Since the sub-pixels 111 having the other colors have the greater influence on the display effect of the display panel, in order to ensure the display effect of the display panel, the start time of providing the data signals to the data lines 30B connected to the sub-pixels 111 having the other colors is controlled to be earlier than the start time of providing the data signals to the data lines 30A connected to the sub-pixels 110 having the first color, that is, the data signals are provided for the data lines 30B connected to the sub-pixels 111 having the other colors first. After providing the data signals for the data lines 30B connected to the sub-pixels 111 having the other colors has been completed, the data signals are provided for the data lines 30A connected to the sub-pixels 110 having the first color, and while providing the data signals for the data lines 30A connected to the sub-pixels 110 having the first color, the second scanning lines Scan2 are controlled to output the control signals to the first control terminals P1B of the data write modules 21B corresponding to the sub-pixels 111 having the other colors to control the data write modules 21B corresponding to the sub-pixels 111 having the other colors to be turned on, so that the data write modules 21B in the pixel circuits 20B corresponding to the sub-pixels 111 having the other colors provide the data signals cached by the data lines 30B for the drive transistors T1B. After providing the data signals for the data lines 30A connected to the sub-pixels 110 having the first color has been completed, the data write modules 21A in the pixel circuits 20A corresponding to the sub-pixels 110 having the first color provide the data signals cached by the data lines 30A for the drive transistors T1A. After providing the data signals for the data lines 30B connected to the sub-pixels 111 having the other colors has been completed, the data write modules 21B in the pixel circuits 20B corresponding to the sub-pixels 111 having the other colors provide the data signals cached by the data lines 30B for the drive transistors T1B, so that the time of providing the data signals cached by the data lines 30B for the drive transistors T1B by the data write modules 21B in the pixel circuits 20B corresponding to the sub-pixels 111 having the other colors changes from original time T22 to time T21, thus increasing the time of the data write modules 21B in the pixel circuits 20B corresponding to the sub-pixels 111 having the other colors to provide the data signals cached by the data lines 30B for the drive transistors T1B, preventing the sub-pixels 111 having the other colors which have the greater influence on the display effect of the display panel from affecting the data signals written into the drive transistors T1B due to insufficient charging time of the scanning signals of the first control terminals P1B of the data write modules 21B, thus affecting the display effect of the display panel.

The sub-pixels 110 having the first color may have the smallest light-emitting efficiency.
Through setting the sub-pixels 110 having the first color as sub-pixels having the smallest light-emitting efficiency in the display panel, that is, the sub-pixels having the first color have the least influence on the display effect of the display panel, even if the charging time of the scanning signals of the first control terminals NA of the data write modules 21A corresponding to the sub-pixels 110 having the first color is insufficient, the sub-pixel having the first color has the smaller influence on the display effect of the display panel, therefore, it is difficult for human eyes to detect it, and the display effect of the display panel is ensured.
Based on the preceding embodiments,
Exemplarily, in
It is to be noted that when the pixel units in the display panel include the red sub-pixels R, the green sub-pixels G and the blue sub-pixels B, the sub-pixels 110 having the first color are the blue sub-pixels B and the sub-pixels 111 having the other colors are the red sub-pixels R and the green sub-pixels G accordingly. In other embodiments, if the pixel units in the display panel include yellow sub-pixels, cyan sub-pixels and pink sub-pixels, the sub-pixels 110 having the first color are the cyan sub-pixels and the sub-pixels 111 having the other colors are the pink sub-pixels R and the yellow sub-pixels G accordingly. Colors of the sub-pixels having the first color and the sub-pixels having other colors are not limited by the embodiments of the present disclosure, and the skilled person in the art may set the colors according to the adaptation scene of the display panel.
The drive transistor T1A in the sub-pixels 110 having the first color may have a width-to-length ratio of a channel region smaller than a width-to-length ratio of a channel region of the drive transistor T1B in the sub-pixels 111 having the other colors.
The width-to-length ratio (W/L) of the channel region A of the drive transistor refers to a ratio of the width W to the length L of an overlapping region where both a semiconductor layer of the drive transistor and a gate of the drive transistor are located, the width of the channel region A refers to a size of the overlapping region in a direction extending along the gate of the driving transistor, and the length of the channel region A refers to a size of the overlapping region in a direction extending along the semiconductor layer of the driving transistor.
Since a white electroluminescent device in the related art differs from a standard white electroluminescent device at certain wavelengths, the light emission brightness corresponding to a sub-pixel region of each color may be different in the case of providing the same data voltage for sub-pixels having different colors. Therefore, the channel regions of the driving transistors in the pixel circuits corresponding to the sub-pixels having the first color and the sub-pixels having the other colors are designed in the present disclosure, the width-to-length ratio of the channel region in a sub-pixel region having the small light emission brightness is increased, thereby increasing the drive current provided by the drive transistor of the sub-pixel region to compensate the loss in the waveband, so as to enable the light emission brightness of the sub-pixel region of each color to tend to be consistent when the sub-pixel region of each color is driven by the same data voltage, and improve the display quality.
Since the pixels corresponding to the sub-pixels 110 having the other colors have greater influence on the display effect of the display panel, the light emission efficiency of the sub-pixels 110 having other colors can be ensured by increasing the width-to-length ratio of the channel region in the pixel circuits 20A corresponding to the sub-pixels 111 having the other colors, thereby ensuring the display effect of the display panel.
The width-to-length ratio of the channel region of the drive transistor T1A in the sub-pixels 110 having the first color may be A1, and the width-to-length ratio of the channel region of the drive transistor T1B in the sub-pixels 111 having the other colors may be A2, where 8≤A2−A1≤12.
The width-to-length ratio A1 of the channel region of the drive transistor T1A in the sub-pixels 110 having the first color and the width-to-length ratio A2 of the channel region of the drive transistor T1B in the sub-pixels 111 having the other colors are configured to satisfy: 8≤A2−A1≤12, that is, by reducing the width-to-length ratio of the channel region of the drive transistor T1A of the sub-pixels 110 having the first color, the reduced channel region can be used for arranging the second transistor newly added by the data write module of each sub-pixel having the first color under the condition that the display of the display panel is not affected.
On the basis of the preceding embodiments,
Exemplarily, as shown in
In order to prevent the voltage of the control terminal of the first drive transistor T1 from affecting the display of the next frame picture when the previous frame picture is displayed, in the embodiment of the present disclosure, the control terminal of the first drive transistor T1 is reset through the first reset module 24 before the data signal is provided for the first drive transistor T1.
Before the light emission stage, an electrode voltage of the light-emitting element D may be reset by the second reset module 25 so that the potential on the electrode of the light-emitting element D in the previous drive period is prevented from affecting the image display in the current drive period.

In the data write stage and stages before the data write stage, the third transistor M3 and the fourth transistor M4 are turned off; and in the light emission stage, the third transistor M3 and the fourth transistor M4 are turned on to enable the drive transistor T1 to drive the light-emitting element D to emit light.
In the data write stage, when the control terminal of the fifth transistor M5 in the threshold compensation module receives the control signal to be turned on, the data voltage signal provided for the drive transistor T1 by the data write module 21 is written into the control terminal of the drive transistor T1 through the fifth transistor M5.
Before the data voltage signal is provided for the first drive transistor T1, the sixth transistor M6 in the first reset module 24 is controlled to be turned on by the control signal, a reset signal inputted by the first reset signal terminal Vref1 is transmitted to the control terminal of the drive transistor T1, and the control terminal of the drive transistor T1 is reset.
Before the light emission stage, the seventh transistor M7 in the second reset module 25 is controlled to be turned on by the control signal, and the second reset signal terminal Vref2 transmits the reset signal to the light-emitting element D to reset the light-emitting element D.
It is to be noted that
Further, the control terminal of the sixth transistor M6 and the control terminal of the seventh transistor M7 may be configured to receive a reset signal output by the same reset signal terminal, thus reducing the number of signal lines in the display panel.
The multiple output terminals of the data selection unit may have a number of n, where n≥6.
When the multiple output terminals of the data selection unit in the display panel have the number of n, and n≥6, for the display panel, it is necessary to provide a data signal for a data line correspondingly connected to a data selection unit through the data selection unit, and the data signal cached by the data line is written into each sub-pixel after providing the data signal for the data line completed. So that within the time of scanning one row of pixels, the time of writing the data signal cached by the data line into each sub-pixel is reduced, resulting in a serious shortage of the time of writing the data signal cached by the data line into each sub-pixel.
Within the time of one frame of the picture, the start time of the effective pulse of the second scanning line Scan2 is t1, the start time of the effective pulse of the first scanning line Scan1 is t2, each data selection unit 41 has n output terminals Out connected to the data lines of the sub-pixels having the first color, and time of providing the data signal for a data line 30A which corresponds to one sub-pixel 110 having the first color and is connected to one of the output terminals Out of the data selection unit is a1, where t1−t2=a1·n.
