[0053] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0054] To address the above technical issues, the present disclosure provides a pixel data processing method, apparatus, display device, and storage medium. The pixel data processing method can be applied to display devices, including but not limited to mobile phones, computers, tablets, e-books, 3D display screens, all-in-one conference machines, electronic whiteboards, and other devices with display functions.

[0055] Referring to Figure 1, the display device includes a timing control module, a pixel array, a scan signal driving module and a data signal driving module. The timing control module (TCON) and the scan signal driving module (Gate Driver) can be implemented using circuits in related technologies and will not be described in detail here. Each pixel unit (Pixel) in the pixel array includes a light-emitting device and a pixel driving circuit for driving the light-emitting device to emit light. Among them, the structure of the light-emitting device of the pixel unit includes multiple types, which can be selected and set according to actual needs. For example, the above-mentioned light-emitting device can be an OLED, a quantum dot light-emitting diode (Quantum Dot Light Emitting Diodes, referred to as QLED) or a micro light-emitting diode (Micro Light Emitting Diodes, referred to as Micro LED), etc., which can be selected according to the specific scenario and are not limited here.

[0056] The display device also includes an IR voltage drop compensation function (not shown in the figure). Its working principle is: when the IR voltage drop compensation function is turned on, the control voltage of each pixel point is compensated in combination with the characteristics of the line voltage drop, so that the control voltage of the pixel units with the same brightness in the same column or row is the same; when the IR voltage drop compensation function is turned off, the farther the distance from the data signal driving module is, the smaller the control voltage is, so that the farther the pixel unit is from the data signal driving module, the lower the brightness is.

[0057] In one embodiment, a data signal driver module (DDIC) can process pixel data of an image to be displayed and convert it into the control voltages required by each column of pixel units; and use these control voltages to drive the pixel units to emit light. In this embodiment, the data signal driver module can be configured to perform a pixel data processing method, as shown in Figure 2, including steps 21 to 23.

[0058] In step 21 , a current current threshold of an image to be displayed is obtained.

[0059] In this step, the data signal driving module of the display device can obtain the image to be displayed from the timing control module (TCON), and then obtain the current current threshold of the image to be displayed. See Figure 3, including steps 31 and 32:

[0060] In step 31, attribute data of the image to be displayed is obtained, wherein the attribute data includes a window display ratio and a brightness adjustment value of the image to be displayed; the window display ratio refers to the ratio of pixels in the image to be displayed whose pixel brightness values ​​exceed a preset brightness threshold.

[0061] Considering that the image to be displayed includes attribute data, for example, the attribute data may include the window display ratio and brightness adjustment value of the image to be displayed. The window display ratio refers to the ratio of pixels in the image to be displayed whose pixel brightness values ​​exceed a preset brightness threshold, and is a statistical value. For example, the image to be displayed includes 100 pixel units, each pixel unit has a brightness range of 0 to 255, and the preset brightness threshold is 200; statistically, the brightness of 20 pixel units in the image to be displayed is between [201, 255] and exceeds 200; therefore, the window display ratio of the image to be displayed is 20 / 100*100%=20%. The brightness adjustment value refers to the brightness of the image to be displayed, for example, 0 to 2000 nit.

[0062] The data signal driving module may analyze the attribute data of the image to be displayed when acquiring the image to be displayed; or the data signal driving module may recalculate the attribute data, which is not limited here.

[0063] In step 32, the product of the window display ratio and the brightness adjustment value is obtained as the current current threshold of the image to be displayed.

[0064] In this step, the data signal driving module may obtain the product of the window display ratio and the brightness adjustment value as the current current threshold of the image to be displayed, that is, current current threshold = window display ratio * brightness adjustment value.

[0065] In step 22 , in response to the current current threshold being greater than a preset current threshold, pixel data of each pixel of the image to be displayed is adjusted to target pixel data, and the IR drop compensation function is disabled.

[0066] In this step, a preset current threshold may be stored in the data signal driving module. The preset current threshold may be in the range of [1200, 2000] nit and may be set according to specific scenarios. In one example, the preset current threshold is 1400 nit.

[0067] In this step, after obtaining the current current threshold, the data signal driving module compares the current current threshold with the preset current threshold to determine the magnitude relationship between the two. When the current current threshold is greater than the preset current threshold, the data signal driving module can adjust the pixel data of each pixel of the image to be displayed to the target pixel data in response to the current current threshold being greater than the preset current threshold. See Figure 4, which includes steps 41 to 43.

[0068] In step 41 , the current current threshold is updated to the preset current threshold.

[0069] Taking into account that when the current current threshold exceeds the preset current threshold, the brightness adjustment value of the image to be displayed will exceed the brightness adjustment value of the image to be displayed, causing the power consumption of the display device to increase, in this step the data signal driving module can correct the current current threshold, for example, update the current current threshold to the above-mentioned preset current threshold, so that the current current threshold reaches the maximum value (that is, the above-mentioned preset current threshold).

[0070] In step 42, a lookup table corresponding to the preset current threshold is obtained; the lookup table includes brightness curves under different window display ratios when the IR drop compensation function is turned off.

[0071] In this step, a lookup table (Look_up Table) is stored in the data signal driving module. The lookup table includes brightness curves at different window display ratios when the IR drop compensation function is turned off. In one example, the lookup table is shown in FIG5 . Referring to Figure 5, the blue curve represents the brightness curve at different window display ratios when the IR voltage drop compensation function is turned on and the brightness is 1600 nits. It is an inclined straight line; the red curve represents the brightness curve at different window display ratios when the IR voltage drop compensation function is turned off and the brightness is 1600 nits. It is a broken line with the inflection point at 25% of the window display ratio; the green curve represents the brightness curve at different window display ratios when the IR voltage drop compensation function is turned on and the brightness is 1400 nits. It is a broken line with the inflection point at 80% of the window display ratio; the purple curve represents the brightness curve at different window display ratios when the IR voltage drop compensation function is turned off and the brightness is 1400 nits. It is a horizontal straight line; the light blue curve represents the brightness curve at different window display ratios when the IR voltage drop compensation function is turned on and the brightness is 1200 nits. It is a horizontal straight line; the orange curve represents the brightness curve at different window display ratios when the IR voltage drop compensation function is turned off and the brightness is 1200 nits. It is a horizontal straight line.

[0072] It should be noted that, referring to Figure 5, at least one brightness curve in the lookup table includes a curve portion with the IPR voltage drop compensation function turned off and a curve portion with the IR voltage drop compensation function turned on, and the window display ratios corresponding to the on / off IR voltage drop compensation functions of different brightness curves are different, or in other words, the inflection point of at least one brightness curve in Figure 5 is different, and the above inflection point is approximately the adjustment point of the current threshold at the current display brightness, thereby achieving the effect of adjusting the current threshold at different display brightness and window display ratios.

[0073] In this step, the data signal driving module may determine the required lookup table according to at least one of the current current threshold, the brightness adjustment value, and the window display ratio.

[0074] In step 43, obtain the pixel data corresponding to each pixel unit of the to-be-displayed image under the brightness curve as the target pixel data.

[0075] In this step, the data signal driving module can obtain the pixel data corresponding to each pixel unit of the to-be-displayed image under the brightness curve. It can be understood that before the current brightness threshold is updated, the pixel data of each pixel unit corresponds to a brightness value; after the current brightness threshold is updated to the preset brightness threshold, the pixel data of each pixel unit is updated to another brightness value. For example, multiply the pixel data before update by an adjustment coefficient (0 < K < 1) to reduce the brightness of each pixel unit. In this way, the data signal driving module can obtain the target pixel data by looking up a table.

[0076] In this step, considering that a region with a small window display ratio in the to-be-displayed image is displayed with high brightness, the data signal driving module can generate a control instruction to turn off the IR voltage drop compensation function.

[0077] After the IR voltage drop compensation function is turned off, there is no need to compensate the control voltage of each pixel unit, which can reduce the backplane power consumption; and since there is a voltage drop (IR drop) between different pixel units, the contrast between the higher and darker regions can be increased, improving the display quality.

[0078] In an embodiment, when the current current threshold is less than or equal to the preset current threshold, the data signal driving module does not correct the pixel data of each pixel unit of the to-be-displayed image, that is, takes the pixel data as the target pixel data and keeps the IR voltage drop compensation function on.

[0079] In step 23, output the target pixel data.

[0080] In this step, the data signal driving module can output the above target pixel data. For example, convert the above target pixel data from digital signal form to analog signal form to write into each pixel unit, achieving the effect of controlling the display of each pixel unit.

[0081] So far, the solution provided by the solution of this embodiment can obtain the current current threshold of the to-be-displayed image; then, in response to the current current threshold being greater than the preset current threshold, adjust the pixel data of each pixel of the to-be-displayed image to the target pixel data and turn off the IR voltage drop compensation function; after that, output the target pixel data. In this way, this solution can adjust the current threshold by adjusting and turning off the IR voltage drop compensation function, which can ensure that the electronic device uses ultra-high brightness to display the image with a small window display ratio under low power consumption, which is beneficial to improving the user experience.

[0082] Describe the above pixel data processing method in combination with specific embodiments, including:

[0083] Referring to FIG. 6 , in this embodiment, it is assumed that the current threshold ≈ window display ratio * brightness adjustment value. The data signal driving module can obtain the image RGB[11:0] to be displayed; then, the window display ratio and the brightness adjustment value are evaluated. For example, the product of the window display ratio and the brightness adjustment value in the attribute data of the image to be displayed is obtained as the current current threshold, and then the current current threshold is compared with the preset current threshold corresponding to the image to be displayed. When the current current threshold is greater than the preset current threshold, the current current threshold is updated to the preset current threshold. Thereafter, the data signal driving module can obtain the lookup table corresponding to the preset current threshold and obtain the pixel data corresponding to each pixel unit of the image to be displayed under the brightness curve as the target pixel data. In addition, a control instruction is generated to turn off the IR voltage drop compensation function to turn off the IR voltage drop compensation function. Alternatively, if the current current threshold is less than or equal to the preset current threshold, the pixel data of each pixel unit is output as the target pixel data.

[0084] Example 1

[0085] When there is no local high brightness screen in text browsing or reading APP, the screen can be as shown in Figure 7. Considering that the screen shown in Figure 7 is only for the purpose of expressing low brightness, the present disclosure has made a certain degree of blurring processing on the text in the screen shown in Figure 7.

[0086] The preset brightness threshold settings are shown in Figure 8. Referring to Figure 8, when the brightness of the image to be displayed is 1200 nits and the window display ratio is 60%, the current brightness threshold exceeds the preset brightness threshold. In this case, the image brightness needs to be adjusted downwards and the IR drop compensation function needs to be disabled. When the brightness of the image to be displayed is 1000 nits and the window display ratio is 72%, the current brightness threshold exceeds the preset brightness threshold. In this case, the image brightness needs to be adjusted downwards and the IR drop compensation function needs to be disabled. When the brightness of the image to be displayed is 900 nits and the window display ratio is 80%, the current brightness threshold exceeds the preset brightness threshold. In this case, the image brightness needs to be adjusted downwards and the IR drop compensation function needs to be disabled. When the brightness of the image to be displayed is 800 nits and the window display ratio is 90%, the current brightness threshold exceeds the preset brightness threshold. In this case, the image brightness needs to be adjusted downwards and the IR drop compensation function needs to be disabled.

[0087] Example 2

[0088] Referring to FIG9 , when the maximum brightness of the display device is 1400 nit, a problem of local overbrightness and blurred image may occur, as shown in the box area in FIG9 . In this embodiment, the maximum brightness of the display device can be increased to 2000 nit, and the brightness curve shown in FIG10 is adopted in combination with the above-mentioned pixel data processing method.

[0089] 10 , ultra-high brightness display is adopted in a local 5% area, and the IR voltage reduction function is turned off at this time, resulting in an image as shown in FIG11 .

[0090] In this embodiment, due to backplane limitations, it is not possible to achieve a localized 5% higher brightness at a display brightness of 1400 nits. Therefore, a solution can be considered to reduce the current threshold when the display brightness reaches 1600 nits at a 100% window display ratio. For example, assuming that the power consumption of a full white screen at 1400 nits at a 100% window display ratio is 4.5W, and the power consumption at 1600 nits is 6W; in this embodiment, by reducing the current threshold across the entire screen, power consumption can be reduced by 1.5W, saving nearly one-third of the power and extending the operating time at 1400 nits by one-third.
