[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0053] To address the aforementioned technical problems, this disclosure provides a pixel data processing method, apparatus, display device, and storage medium. The pixel data processing method is applicable to display devices, including but not limited to mobile phones, computers, tablets, e-readers, 3D displays, all-in-one conference machines, and electronic whiteboards, all devices with display functions.

[0054] See 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 from related technologies, which will not be elaborated upon here. Each pixel unit in the pixel array includes a light-emitting device and a pixel driving circuit for driving the light-emitting device to emit light. The structure of the light-emitting device in the pixel unit can be varied and can be selected according to actual needs. For example, the light-emitting device can be an OLED, a quantum dot light-emitting diode (QLED), or a micro light-emitting diode (Micro LED), etc., and the selection is not limited here, depending on the specific scenario.

[0055] The display device also includes an IR voltage drop compensation function (not shown in the figure). Its working principle is as follows: when the IR voltage drop compensation function is turned on, the control voltage of each pixel is compensated based on the characteristics of the line voltage drop, so that the control voltage of the same brightness of the pixel unit in the same column or row is the same; when the IR voltage drop compensation function is turned off, based on the characteristics of the line voltage drop, the farther away from the data signal driving module, the smaller the control voltage, so that the pixel unit is farther away from the data signal driving module and the brightness is extremely low.

[0056] In one embodiment, the Data Signal Driving Module (DDIC) can process the pixel data of the image to be displayed and convert it into the control voltage required by each column of pixel units; and use the control voltage to drive the pixel units to emit light. In this embodiment, the Data Signal Driving Module can be configured to perform a pixel data processing method, see [link to relevant documentation]. Figure 2 This includes steps 21 to 23.

[0057] In step 21, the current current threshold of the image to be displayed is obtained.

[0058] In this step, the data signal drive 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 [link to relevant documentation]. Figure 3 This includes steps 31 and 32:

[0059] In step 31, attribute data of the image to be displayed is obtained. The attribute data includes the window display ratio and brightness adjustment value of the image to be displayed. The window display ratio refers to the proportion of pixels in the image to be displayed whose pixel brightness value exceeds a preset brightness threshold.

[0060] Considering that the image to be displayed includes attribute data, such as the window display ratio and brightness adjustment value, the window display ratio refers to the proportion of pixels in the image whose brightness value exceeds a preset brightness threshold; it is a statistical value. For example, the image to be displayed includes 100 pixel units, each with a brightness range of 0 to 255, and a preset brightness threshold of 200; statistically, 20 pixel units in the image have a brightness between [201, 255] and exceed 200; therefore, the window display ratio of this image is 20 / 100*100% = 20%. The brightness adjustment value refers to the brightness of the image when it is displayed, for example, 0 to 2000 nits.

[0061] The data signal driving module can parse the attribute data of the image to be displayed when acquiring the image; or, the data signal driving module can recalculate the above attribute data, which is not limited here.

[0062] 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.

[0063] In this step, the data signal driving module can 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, the current current threshold = window display ratio * brightness adjustment value.

[0064] In step 22, in response to the current current threshold being greater than the preset current threshold, the pixel data of each pixel of the image to be displayed is adjusted to the target pixel data, and the IR voltage drop compensation function is turned off.

[0065] In this step, the data signal drive module can store a preset current threshold. The preset current threshold can be in the range of [1200, 2000] nits and can be set according to the specific scenario. In one example, the preset current threshold is 1400 nits.

[0066] 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 their magnitude relationship. 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 in 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 [link to relevant documentation]. Figure 4 This includes steps 41 to 43.

[0067] In step 41, the current current threshold is updated to the preset current threshold.

[0068] Considering that when the current current threshold exceeds the preset current threshold, the brightness adjustment value of the image to be displayed will be exceeded when the image is displayed, resulting in increased power consumption of the display device, the data signal driving module can correct the current current threshold in this step. For example, the current current threshold can be updated to the preset current threshold mentioned above, so that the current current threshold reaches its maximum value (i.e., the preset current threshold mentioned above).

[0069] 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 voltage drop compensation function is turned off.

[0070] In this step, the data signal drive module stores a lookup table, which includes brightness curves for different window display ratios with IR drop compensation disabled. In one example, the lookup table is as follows: Figure 5 As shown. See also Figure 5 The blue curve represents the brightness curve at different window display ratios with IR drop compensation enabled and 1600 nits brightness; it is a sloping straight line. The red curve represents the brightness curve at different window display ratios with IR drop compensation disabled and 1600 nits brightness; it is a broken line with the inflection point at 25% window display ratio. The green curve represents the brightness curve at different window display ratios with IR drop compensation enabled and 1400 nits brightness; it is a broken line with the inflection point at 80% window display ratio. The purple curve represents the brightness curve at different window display ratios with IR drop compensation disabled and 1400 nits brightness; it is a horizontal straight line. The light blue curve represents the brightness curve at different window display ratios with IR drop compensation enabled and 1200 nits brightness; it is a horizontal straight line. The orange curve represents the brightness curve at different window display ratios with IR drop compensation disabled and 1200 nits brightness; it is a horizontal straight line.

[0071] It should be noted that, please continue to refer to Figure 5 The lookup table must contain at least one brightness curve that includes both a portion with IPR drop compensation disabled and a portion with IR drop compensation enabled, and the window display ratios corresponding to the on / off IR drop compensation function differ for different brightness curves, or in other words... Figure 5 At least one of the brightness curves has a different inflection point. The inflection point is approximately the adjustment point of the current threshold under the current display brightness, thereby achieving the effect of adjusting the current threshold under different display brightness and window display ratio.

[0072] In this step, the data signal drive module can determine the required lookup table based on at least one of the current threshold, brightness adjustment value, and window display ratio.

[0073] 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.

[0074] 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 the 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 means of look-up table.

[0075] 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.

[0076] 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; moreover, due to the voltage drop (IR drop) between different pixel units, the contrast between the higher region and the darker region can be increased, improving the display quality.

[0077] 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 turned on.

[0078] In step 23, output the target pixel data.

[0079] 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, so as to achieve the effect of controlling the display of each pixel unit.

[0080] So far, the solution provided by the embodiment of the present invention 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; then, output the target pixel data. In this way, by adjusting and turning off the IR voltage drop compensation function to adjust the current threshold, this solution can ensure that the electronic device uses ultra-high brightness to display the image under a small window display ratio in the case of low power consumption, which is beneficial to improving the user experience.

[0081] The pixel data processing method described above, in conjunction with specific embodiments, includes:

[0082] See Figure 6 In this embodiment, it is assumed that the current threshold ≈ window display ratio * brightness adjustment value. The data signal driving module can acquire the RGB[11:0] of the image to be displayed; then, it evaluates the window display ratio and brightness adjustment value. For example, it acquires the product of the window display ratio and brightness adjustment value in the attribute data of the image to be displayed as the current current threshold, and then compares the current current threshold 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. After that, the data signal driving module can acquire the lookup table corresponding to the preset current threshold, acquire the pixel data corresponding to each pixel unit of the image to be displayed under the brightness curve, and use it as the target pixel data. In addition, it generates a control command to turn off the IR voltage drop compensation function to turn off the IR voltage drop compensation function. Or, 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.

[0083] Example 1

[0084] In text browsing or reading apps where there are no areas of high brightness, the screen can appear as follows: Figure 7 As shown. Considering Figure 7 The image shown is only for illustrating low brightness; this disclosure is for illustrative purposes only. Figure 7 The text in the image shown has been blurred to some extent.

[0085] At this time, the preset brightness threshold is set as follows: Figure 8 As shown. See also 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 reduced and the IR voltage drop compensation function should be disabled. Similarly, 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. Again, the image brightness needs to be reduced and the IR voltage drop compensation function should 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 reduced and the IR voltage drop compensation function should be disabled. Finally, 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 reduced and the IR voltage drop compensation function should be disabled.

[0086] Example 2

[0087] See Figure 9When the maximum brightness of the display device is 1400 nits, localized areas may become too bright, resulting in a blurry image. Figure 9 The area within the box is shown. In this embodiment, the maximum brightness of the display device can be increased to 2000 nits. Combined with the pixel data processing method described above, a brightness curve as shown in Figure 10 is used.

[0088] See Figure 10 In a localized 5% area, ultra-high brightness is used for display. At this time, the IR voltage reduction function is turned off, resulting in... Figure 11 The image shown.

[0089] In this embodiment, due to the limitations of the back panel, a localized 5% higher brightness cannot be achieved at a display brightness of 1400 nits. A solution could be considered to reduce the current threshold when the display brightness is 1600 nits at 100% window size. For example, assuming the power consumption of a full white screen at 1400 nits brightness is 4.5W at 100% window size and 6W at 1600 nits brightness, this embodiment can reduce power consumption by 1.5W by applying a lower current threshold across the entire screen, saving nearly one-third of the power and extending the usage time at 1400 nits brightness by one-third.
