[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0053] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0054] As mentioned in the background, display panels that use the same driving capability for different application conditions cannot meet the current requirements for high refresh rates and low power consumption. With the increase in screen resolution and refresh rate, there are even higher requirements for the power consumption, energy saving and environmental protection of display panels and display devices.

[0055] Figure 1 A schematic flowchart of an exemplary method 100 for controlling a display panel, as provided in this application, is shown. This method can be applied to the control unit of a display panel.

[0056] The display panel may include a control unit, a driving unit, and a display unit. The display unit may include an array of multiple pixel units; when each pixel unit is illuminated based on acquired display data, the display function is achieved. The driving unit provides driving signals to the pixel units to control their illumination; optionally, the driving unit may be a source driver, a gate driver, or a level shifter. The control unit provides control signals to the driving unit to control the driving unit to output driving signals that meet the display data requirements; optionally, the control unit may be a timing controller (Tcon) or similar structure.

[0057] In some embodiments, method 100 may include the following steps.

[0058] In step S102, the display data is obtained.

[0059] In step S104, display parameters are obtained based on the display data. These display parameters represent the display state of the display unit.

[0060] In some embodiments, the display parameters may be the refresh rate of the display panel (e.g., high refresh rate and low refresh rate), and different refresh rates can cause the display unit to be in a display state with different refresh rates; the display parameters may be the pixel grayscale values ​​of the display panel, and different grayscale values ​​can cause the display panel or the pixels in the display panel to be in a display state with different brightness; the display parameters may also be parameters that can affect the display of the display unit, such as the horizontal driving time, charging time, charging voltage, and polarity of the display panel, and this embodiment does not limit these parameters.

[0061] In step S106, the driving capability of the driving unit is determined based on the display parameters. Further, different driving capabilities can be determined based on different display parameters.

[0062] In some embodiments, the display parameters may include the row driving time. Determining different driving capabilities based on different display parameters further includes: obtaining a preset correspondence between display parameters and driving capabilities, and determining the driving capability based on the row driving time and the correspondence. The correspondence between display parameters and driving capabilities can be obtained based on a preset driving force setting lookup table, an example lookup table is shown in Table 1.

[0063] It should be noted that after determining the drive capability, the drive capability of the drive unit (e.g., the source driver) needs to be set according to the drive capability. This can be set within the horizontal blanking time (H-blanking), the vertical blanking time (V-blanking), or through other means.

[0064] Table 1: Driving Force Setting Comparison Table

[0065] Line drive time / us Drive capability 2.5 31 3.0 25 3.5 20 4.0 15 4.5 13 5.0 8

[0066] In some embodiments, the display parameters may include a first refresh rate and a second refresh rate. Determining different driving capabilities based on different display parameters further includes: obtaining a preset correspondence between display parameters and driving capabilities; determining a first driving capability based on the first refresh rate and the correspondence; and determining a second driving capability based on the second refresh rate and the correspondence. The correspondence between display parameters and driving capabilities can be obtained based on a preset driving force setting lookup table. An exemplary lookup table can replace the driving time in the first column of Table 1 with the values ​​of the first refresh rate and the second refresh rate.

[0067] It should be noted that after determining the first driving capability, the driving capability of the driving unit (e.g., the source driver) needs to be set according to the first driving capability. This can be set within the horizontal blanking time (H-blanking), the vertical blanking time (V-blanking), or through other means.

[0068] In some embodiments, the display unit may include a plurality of pixel units arranged in an array. The display unit may also include a first pixel and a second pixel. The first pixel and the second pixel may be two adjacent pixel units in the plurality of pixel units arranged in the array (e.g., two pixel units in adjacent rows of the same column, or two pixel units in adjacent columns of the same row), or two non-adjacent pixel units. This embodiment does not limit this. The display parameters may include a first grayscale value of the first pixel and a second grayscale value of the second pixel. Determining different driving capabilities according to different display parameters further includes: obtaining a first grayscale difference between the first grayscale value of the first pixel and the second grayscale value of the second pixel; obtaining a preset correspondence between the grayscale difference and the driving capability; and determining a third driving capability based on the first grayscale difference and the correspondence. The correspondence between the display parameters and the driving capability can be obtained based on a preset driving force setting lookup table. An exemplary lookup table is shown in Table 2. It should be noted that Table 2 is only an exemplary driving force setting lookup table, and the maximum driving capability value in the table is 31. In the table, Sline represents source drive lines Y1-Y1440, Line N-1 represents the pixel grayscale displayed in the previous row of the display unit, and Line N represents the pixel grayscale displayed in the current row of the display unit. The third driving capability can be determined by comparing the pixel grayscale value to be displayed (Line N) with the pixel grayscale value displayed in the same row on the same source drive line (Line N-1) to determine the corresponding driving capability. When the first pixel needs to be illuminated, the first grayscale value of the first pixel and the second grayscale value of the second pixel can be obtained respectively, and the first grayscale difference between the first and second grayscale values ​​can be calculated. Based on the first grayscale difference and the driving force setting lookup table, the corresponding driving capability is obtained, and the first pixel is illuminated using this driving capability. Taking the pixel grayscale corresponding to Y1 in Table 2 as an example, the grayscale of the Line N pixel corresponding to Y1 is V143 (i.e., the first grayscale value of the first pixel), and the grayscale of the Line N-1 pixel corresponding to the previous row is V132 (i.e., the second grayscale value of the second pixel). The driving capability value corresponding to the difference between V143 and V132 (i.e., the first grayscale difference between the first grayscale value and the second grayscale value) is 11. Therefore, the driving capability value 11 is determined as the driving capability of the source driver and the Line N pixel corresponding to Y1 is lit up with this driving capability.

[0069] It should be noted that after determining the third driving capability, the driving capability of the driving unit (e.g., the source driver) needs to be set according to the third driving capability. This can be set within the horizontal blanking time (H-blanking), the vertical blanking time (V-blanking), or through other means.

[0072] In step S108, the driving unit is controlled to provide a driving signal to the display unit with the driving capability.

[0073] In some embodiments, controlling the driving unit to provide a driving signal to the display unit with the driving capability further includes: in response to the display unit being in a display state corresponding to the first refresh frequency, controlling the driving unit to provide a driving signal to the display unit with the first driving capability; and in response to the display unit being in a display state corresponding to the second refresh frequency, controlling the driving unit to provide a driving signal to the display unit with the second driving capability, wherein the first refresh frequency is greater than the second refresh frequency, and the first driving capability is greater than the second driving capability. The first refresh frequency may be a high refresh rate (HRR), and the second refresh rate may be a low refresh rate (LRR).

[0074] It's understandable that the terms "high refresh rate" and "low refresh rate" are relative; for example, a high refresh rate could be 480Hz, and a low refresh rate could be 240Hz. In practical applications, users can send a selection signal for the refresh rate to the display panel via the toggle button in the system menu, choosing between a high or low refresh rate for display.

[0075] It should be noted that increasing the refresh rate shortens the charging time of display unit pixels, leading to insufficient pixel charging time and potentially causing display defects, thus affecting the display panel's performance. Therefore, in related technologies, to improve the driving capability of the driving unit and increase pixel charging time, strong driving capabilities are employed for both high and low refresh rates. This enhances the pixel charging speed at high refresh rates, ensuring that pixels are fully charged to the target voltage within a shorter charging time. However, employing strong driving capabilities at low refresh rates increases the power consumption of the display panel. Therefore, in some embodiments, a corresponding level of driving capability can be selected based on the refresh rate to reduce power consumption.

[0076] See Figure 2A and Figure 2B In related technologies, under high refresh rate charging time ( Figure 2A The charging time is short and the driving capability is strong. It is fully charged to the target voltage V120 at the Tcharge HRR time. Under low refresh rate charging time (… Figure 2AThe Tcharge LRR in the model has a relatively long charging time. Since the drive capability setting is the same as under HRR, it is fully charged to the target V120 grayscale voltage at the Tcharge HRR time. However, during the period from Tcharge HRR to Tcharge LRR, LRR only maintains the target V120 grayscale voltage with a strong drive capability, which will generate unnecessary power consumption.

[0077] In some embodiments, the control unit may be a timing controller, and the drive unit may be a source driver. The operation of the timing controller can be divided into three stages: t1, t2, and t3.

[0078] In phase t1, the timing controller obtains the row drive time or the display data, and obtains the refresh rate value based on the display data.

[0079] In stage t2, the timing controller obtains the optimal driving force value and determines the driving capability based on the value of the row driving time or refresh frequency and the optimal driving capability setting lookup table.

[0080] In stage t3, the drive capability of the source driver can be set, either during the line blanking time, during the field blanking time, or through other means.

[0081] For the optimization effect of this embodiment, please refer to... Figure 2B During high refresh rate charging times, the driving capability remains unchanged. During low refresh rate charging times, the lower driving capability level corresponding to the optimal driving capability setting table is selected. In this case, the pixels of the display unit slowly reach the target voltage V120 grayscale voltage at the Tcharge LRR time with a lower driving capability, or it can be fully charged to the target voltage V120 grayscale voltage within ±5% of the Tcharge LRR time. This reduces the power consumption generated by maintaining the target voltage with a strong driving capability during the Tcharge HRR to Tcharge LRR stage in related technologies, thus avoiding power waste.

[0082] In some embodiments, the display unit may include pixels. Controlling the driving unit to provide a driving signal to the display unit with the second driving capability further includes: obtaining a first charging time based on the second refresh frequency, and controlling the driving unit to fully charge the pixel to a target voltage with the second driving capability during the first charging time. The first charging time may be a line driving time obtained based on the refresh frequency.

[0083] In some embodiments, controlling the driving unit to provide a driving signal to the display unit with the driving capability further includes: controlling the driving unit to provide a driving signal to the display unit with the third driving capability. Further, the driving unit is controlled to fully charge the first pixel to a target voltage with the third driving capability during a preset second charging time; wherein the difference between the preset second charging time and the actual charging time is less than the actual charging time. The preset second charging time allows for an error of ±5%.

[0084] In related technologies, the driving capability values ​​of each source driver in the display panel are set to be consistent. For example... Figure 3A As shown, the voltage difference between two adjacent rows of pixels in source driver SD1 is smaller (narrowδV), ranging from V0 to V120, while the voltage difference between two adjacent rows of pixels in source driver SD2 is larger (wideδV), ranging from V0 to V160. Under the same charging time (Tcharge), the charging time for narrowδV is shorter, while the charging time for wideδV is longer. Different display grayscales correspond to different voltage differences. In existing technologies, using the same driving capability for different display grayscales leads to different charging times for different pixels within the same charging time, resulting in charging imbalances and causing problems such as uneven display on the display panel.

[0085] In some embodiments, the control unit may be a timing controller, and the drive unit may be a source driver. The operation of the timing controller can be divided into three stages: t1, t2, and t3.

[0086] In stage t1, the grayscale of each row of pixels is stored in the memory of the timing controller.

[0087] In stage t2, the timing controller compares the grayscale of the current row to be displayed with the grayscale of the previous row, obtains the optimal driving force value based on the difference between the grayscale of the current row and the previous row and the optimal driving force setting lookup table, and determines the driving capability.

[0088] In stage t3, the drive capability of the source driver can be set, either during the line blanking time, during the field blanking time, or through other means.

[0089] For the optimization effect of this embodiment, please refer to... Figure 3BBased on related technologies, for the source driver SD1 with a small voltage difference, when a suitable driving capability is selected, it can be fully charged to the target V120 grayscale voltage at time Tcharge, or it can be fully charged to the target V120 grayscale voltage within ±5% of time Tcharge. For the source driver SD2 with a large voltage difference, when a suitable driving capability is selected, it can be fully charged to the target V160 grayscale voltage at time Tcharge. By selecting different driving capabilities for different display grayscales, different pixels are charged at different charging speeds, and all pixels can be fully charged to the target voltage within the same time, thus solving the problem of display unevenness caused by charging imbalance.
