Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display panel control method and device, electronic equipment and storage medium. BACKGROUND

[0002] In the field of display technology, with the continuous improvement of product performance, how to reduce the power consumption of display devices has become an important goal of industry development and technological innovation. At present, there are at least two problems in display technology in terms of power consumption.

[0003] First, the redundant power consumption in the data transmission process. The existing display devices generally use fixed bit width signal mode, such as traditional 8-Bit data transmission. However, when displaying pictures with less rich colors, complete 8-Bit data is not needed to accurately express color information, and the transmission and processing of redundant data cause unnecessary energy loss.

[0004] Second, the huge power consumption of the backlight module. In display devices, the backlight module is the main energy consumption unit, and its power consumption usually accounts for 85% to 95% of the total power consumption of the whole machine. In the prior art, the backlight module is maintained at a high brightness state for a long time, even when displaying dark pictures, the backlight module still outputs at a high brightness. At this time, the high brightness output has no gain for picture presentation, but constitutes the main power consumption burden.

[0005] In summary, the display devices in the prior art still have a lot of energy waste, therefore, there is an urgent need for a technical solution that can effectively reduce the overall power consumption of display devices while ensuring the display effect as much as possible. SUMMARY

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0064] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity and clarity, the description of the specific examples in the following text will be described. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to the numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed.

[0065] In order to effectively reduce the overall power consumption of the display device while ensuring the display effect as much as possible, the present application provides a display panel control method, device, electronic equipment and storage medium.

[0066] Figure 1 A flowchart of a display panel control method provided by an embodiment of the present application is shown in Figure 1 The display panel control method provided by the embodiment of the present application specifically includes the following steps:

[0067] S1: obtaining a to-be-displayed data frame and determining display parameters of the to-be-displayed data frame; wherein the display parameters at least include the basic pixel driving voltage of each pixel unit in the to-be-displayed data frame;

[0068] S2: according to the display parameters, determining a target data bit width for transmitting the to-be-displayed data frame from a plurality of data bit widths including at least a first data bit width and a second data bit width; wherein the first data bit width is higher than the second data bit width;

[0069] And / or,

[0070] S3: according to the display parameters, increasing the basic pixel driving voltage of each pixel unit in the to-be-displayed data frame, and synchronously reducing the corresponding backlight brightness of the to-be-displayed data frame;

[0071] Specifically, the control method of the display panel provided in the embodiments of the present application can be applied to a driving board of a display device. The driving board is connected to a display panel of the display device, receives a to-be-displayed data frame transmitted by a data source, processes the to-be-displayed data frame, and transmits the to-be-displayed data frame to the display panel and drives the display panel to display the to-be-displayed data frame.

[0072] The driving board first acquires the to-be-displayed data frame from the data source. The data source can be a personal computer, a graphics card, an industrial computer or the like.

[0073] After acquiring the to-be-displayed data frame, the driving board parses display parameters of the to-be-displayed data frame. The display parameters at least include basic pixel driving voltages of each pixel unit in the to-be-displayed data frame. The basic pixel driving voltages are only associated with a display picture corresponding to the to-be-displayed data frame and are determined when the to-be-displayed data frame is generated. In some other examples, the display parameters can further include a gray scale value, a timing control signal, a brightness control signal and the like of the to-be-displayed data frame.

[0074] On one hand, the driving board determines a target data bit width for transmitting the to-be-displayed data frame from a plurality of data bit widths based on the display parameters of the to-be-displayed data frame.

[0075] In a feasible embodiment, the data bit widths available for the driving board to select at least include a first data bit width and a second data bit width. The first data bit width is higher than the second data bit width.

[0076] As a specific example, the first data bit width is a default data bit width of the display panel, for example, 8 bits, and the second data bit width is a data bit width lower than the default data bit width of the display panel, for example, 6 bits.

[0077] On the other hand, the driving board adjusts the basic pixel driving voltages of each pixel unit in the to-be-displayed data frame based on the display parameters of the to-be-displayed data frame. The basic pixel driving voltages of each pixel unit are increased. Meanwhile, the driving board also synchronously adjusts the brightness of a backlight corresponding to the to-be-displayed data frame, and the brightness of the backlight corresponding to the to-be-displayed data frame is decreased.

[0078] The method provided by the embodiments of the present application controls the display panel of the display device, thereby reducing the overall power consumption of the display device. In one aspect, the method provided by the embodiments of the present application dynamically adjusts the data bit width of the to-be-displayed data frame according to the display parameter of the to-be-displayed data frame, thereby adaptively selecting a suitable data bit width according to the actual picture condition of the to-be-displayed data frame, avoiding unnecessary energy loss caused by transmission and processing of redundant data. In another aspect, the method provided by the embodiments of the present application improves the basic pixel driving voltage of the pixel unit in the to-be-displayed data frame, while reducing the corresponding backlight brightness of the to-be-displayed data frame. The energy consumption of the backlight module is reduced by reducing the corresponding backlight brightness of the to-be-displayed data frame, and the overall light transmittance of the pixel unit is increased by improving the basic pixel driving voltage of the pixel unit in the to-be-displayed data frame, thereby ensuring the display effect.

[0079] It can be seen that the method provided by the embodiments of the present application controls the display panel from multiple aspects, effectively reduces the energy consumption of the display panel, and reduces the overall power consumption of the display device while ensuring the display effect of the display panel.

[0080] It can be understood that, in the above technical solutions provided by the embodiments of the present application, step S2 and step S3 can be executed simultaneously or any one of them can be executed. Regardless of which step corresponds to the technical solution being executed, the technical effect of reducing the overall power consumption of the display device can be achieved.

[0081] In some scenarios, the display picture color information corresponding to the to-be-displayed data frame is relatively single (for example, the display picture is night, a single picture screen saver, or night eye protection mode reading text, etc.). If the default data bit width (for example, the first data bit width) is used to transmit these to-be-displayed data frames, the transmission and processing of part of the redundant data will cause energy waste.

[0082] To solve the problem that the transmission bit width of the to-be-displayed data frame in a monotonous picture may cause energy waste, in a feasible embodiment of the present application, a target data bit width for transmitting the to-be-displayed data frame is determined from a plurality of data bit widths including at least a first data bit width and a second data bit width according to a display parameter, comprising:

[0083] The average values of the pixel driving voltages of the continuous multiple frames of to-be-displayed data frames are calculated respectively; wherein the average value of the pixel driving voltage is the average value of the basic pixel driving voltages of each pixel unit in the to-be-displayed data frame;

[0084] The average values of the pixel driving voltages of each frame of to-be-displayed data frames are compared with a voltage threshold value respectively; wherein the voltage threshold value is the voltage value of the pixel driving voltage corresponding to the preset gray scale standard value;

[0085] In a case where the average value of the pixel driving voltage of each frame of the to-be-displayed data frame is less than or equal to the voltage threshold, the target data bit width of each frame of the to-be-displayed data frame is determined as the second data bit width.

[0086] Specifically, a plurality of continuous frames of to-be-displayed data frames (for example, three continuous frames of to-be-displayed data frames) are acquired, and display parameters of each frame of the to-be-displayed data frame are determined, that is, the basic pixel driving voltage of each pixel unit in each frame of the to-be-displayed data frame is determined. After the basic pixel driving voltage of each pixel unit in each frame of the to-be-displayed data frame is determined, the average value of the pixel driving voltage of each frame of the to-be-displayed data frame is calculated.

[0087] The average value of the pixel driving voltage of each frame of the to-be-displayed data frame is compared with the voltage threshold. The voltage threshold is determined by a person skilled in the art in advance and written, and specifically, the voltage value of the pixel driving voltage corresponding to the preset gray scale standard value is used as the voltage threshold. As a specific example, the preset gray scale standard value can be 64 gray scales.

[0088] The comparison result of the average value of the pixel driving voltage of each frame of the to-be-displayed data frame and the voltage threshold is determined. In a case where the average value of the pixel driving voltage of each frame of the to-be-displayed data frame is less than or equal to the voltage threshold, the target data bit width of each frame of the to-be-displayed data frame is determined as the second data bit width.

[0089] In an embodiment of the present application, the default transmission bit width of each frame of the to-be-displayed data frame is 8 bits, and the target transmission bit width of each frame of the to-be-displayed data frame is currently determined as 6 bits. At this time, the last two bits of each frame of the to-be-displayed data frame are removed, and the data bit width of 8 bits is converted to the data bit width of 6 bits.

[0090] It can be understood that, in a case where the average value of the pixel driving voltage of each frame of the to-be-displayed data frame is less than or equal to the voltage threshold, it can be considered that the display picture corresponding to the plurality of continuous frames of to-be-displayed data frames currently acquired is relatively stable, and the brightness is relatively low. At this time, the transmission of these to-be-displayed data frames using a lower data bit width will not affect the display effect of the display picture, and at the same time, the redundant transmission process is effectively avoided, and the overall energy consumption is as low as possible.

[0091] In an embodiment of the present application, after the average value of the pixel driving voltage of each frame of the to-be-displayed data frame is compared with the voltage threshold, the method further comprises:

[0092] In a case where the average value of the pixel driving voltage of any frame of the to-be-displayed data frame is greater than the voltage threshold, the difference between the average values of the pixel driving voltages of the adjacent two frames of the to-be-displayed data frame is calculated.

[0093] In a case where the difference between the average values of the pixel driving voltages of the two adjacent frames of to-be-displayed data frames is greater than a preset first difference threshold, it is determined that the target data bit width of the latter frame of to-be-displayed data frames is a second data bit width to which a frame rate control technology is applied.

[0094] In a case where the difference between the average values of the pixel driving voltages of the two adjacent frames of to-be-displayed data frames is greater than a preset second difference threshold, it is determined that the target data bit width of the latter frame of to-be-displayed data frames is the first data bit width; and the second difference threshold is greater than the first difference threshold.

[0095] Specifically, when the driving board detects that the average value of the pixel driving voltage of at least one frame of to-be-displayed data frames in a plurality of continuous frames is higher than a preset voltage threshold, it indicates that the current display picture can no longer be in a stable low brightness state, and there is a change in brightness or a picture switching, and the color information contained is also significantly increased. At this time, the difference between the average values of the pixel driving voltages of the two adjacent frames of to-be-displayed data frames is calculated, the degree of change of the picture is quantified through the difference between the average values of the pixel driving voltages of the two adjacent frames of to-be-displayed data frames, and the target data bit width of the to-be-displayed data frame is determined.

[0096] The calculated difference between the average values of the pixel driving voltages of the two adjacent frames of to-be-displayed data frames is compared with the preset first difference threshold and the second difference threshold, and the two difference thresholds are preset by a person skilled in the art according to experience, so as to determine whether the degree of change of the display picture of the latter frame of to-be-displayed data frames relative to the former frame of to-be-displayed data frames is moderate or severe.

[0097] If the calculated difference is greater than the first difference threshold but less than or equal to the second difference threshold, it indicates that the degree of change of the display picture of the latter frame of to-be-displayed data frames relative to the former frame of to-be-displayed data frames is moderate, and at this time, the target data bit width of the latter frame of to-be-displayed data frames is determined to be a second data bit width to which a frame rate control (FRC) technology is applied. For example, a 6bit+FRC mode is used for transmission, and the color depth between 6bit and 8bit is simulated through fast alternative display of pixel points, so as to reduce the data transmission amount and ensure the display effect of the display picture.

[0098] If the calculated difference is greater than the second difference threshold, it indicates that the degree of change of the display picture of the latter frame of to-be-displayed data frames relative to the former frame of to-be-displayed data frames is severe, and at this time, the target data bit width of the latter frame of to-be-displayed data frames is determined to be the first data bit width. For example, an 8bit mode is used for transmission, so as to ensure the display effect of the display picture.

[0099] Through the technical solutions provided in the above embodiments, the application can intelligently perform dynamic switching among the first data bit width, the second data bit width to which the FRC is applied, and the third data bit width, when detecting the brightness change of a picture, so as to realize the accurate balance between power consumption and picture quality.

[0100] In an available embodiment of the application, the to-be-displayed data frame is divided into a plurality of display regions, each display region including a plurality of pixel unit columns, and a target data bit width for transmitting the to-be-displayed data frame is determined from a plurality of data bit widths including at least the first data bit width and the second data bit width according to a display parameter, and the method further includes:

[0101] Comparing the adjacent two to-be-displayed data frames, the brightness change degree of each display region in the latter to-be-displayed data frame is determined according to the comparison result of the adjacent two to-be-displayed data frames;

[0102] Each display region in the latter to-be-displayed data frame is determined as a first display region, a second display region, or a third display region according to the brightness change degree, wherein the brightness change degree of the first display region is greater than that of the second display region, and the brightness change degree of the second display region is greater than that of the third display region;

[0103] The target data bit width of the display region in the latter to-be-displayed data frame that is the first display region is determined as the first data bit width, the target data bit width of the display region in the latter to-be-displayed data frame that is the second display region is determined as the second data bit width to which the frame frequency control technology is applied, and the target data bit width of the display region in the latter to-be-displayed data frame that is the third display region is determined as the second data bit width.

[0104] Specifically, the above embodiments are applicable to the case where only a local region in a picture has a brightness change. The driving board first divides a single-frame display picture into a plurality of preset display regions, and then judges the intensity of the brightness change degree of each display region by comparing the adjacent two to-be-displayed data frames, and according to the brightness change degree from high to low, the driving board classifies each display region into a first display region, a second display region, or a third display region.

[0105] For the first display area with the most dramatic change in brightness, the driving board uses a first data bit width (e.g. 8 bits) for transmission to ensure the most accurate presentation of color and details in the key part of the picture. For the second display area with moderate change in brightness, a second data bit width (e.g. 6 bits+FRC) with FRC technology is used for transmission to ensure smooth transition in visual effect while saving power consumption. For the third display area with the weakest change in brightness or no change, a second data bit width (e.g. 6 bits) is directly used for transmission to maximize the transmission power saving of the display area. Through this embodiment, differentiated and refined power consumption management of different areas within a single frame of picture is achieved.

[0106] Further, the degree of change in brightness of adjacent two frames of to-be-displayed data frames can be determined based on the difference between the basic pixel driving voltage of each pixel unit in the latter frame of to-be-displayed data frame and the basic pixel driving voltage of the corresponding pixel unit in the former frame of to-be-displayed data frame, so as to classify the display area into the first display area, the second display area or the third display area.

[0107] In a feasible embodiment of the present application, the degree of change in brightness of each display area in the latter frame of to-be-displayed data frame is determined according to the comparison result of adjacent two frames of to-be-displayed data frames, comprising:

[0108] The difference between the basic pixel driving voltage of each pixel unit in the latter frame of to-be-displayed data frame and the basic pixel driving voltage of the corresponding pixel unit in the former frame of to-be-displayed data frame is calculated respectively;

[0109] The average value of the difference of each display area in the latter frame of to-be-displayed data frame is determined according to the calculation result;

[0110] The average value of the difference is compared with the preset third difference threshold value, and the degree of change in brightness of each display area in the latter frame of to-be-displayed data frame is determined according to the comparison result of the average value of the difference and the third difference threshold value.

[0111] Specifically, for adjacent two frames of to-be-displayed data frames, the difference in basic pixel driving voltage of each pixel unit corresponding in position in the latter frame and the former frame of picture is calculated one by one, so as to obtain the pixel-level voltage change amount covering the full screen.

[0112] Subsequently, the voltage change amount of all pixel units in each display area is averaged in a preset display area unit, and the average value of the difference of the display area is calculated, which can accurately represent the trend and amplitude of the overall change in brightness of the display area.

[0113] Finally, the average value of the difference of each display area is compared with a third difference threshold. According to the comparison result, it is determined which level the luminance variation degree of the display area belongs to, and the display area is classified as a first display area, a second display area or a third display area, and then a corresponding target data bit width transmission strategy is executed.

[0114] Referring to Figure 2a In some actual examples, the display picture can be divided into five preset display areas, and the default data bit width of the to-be-displayed data frame is 8 bits when the display panel just starts to work. Referring to Figure 2b After adjustment based on the technical solutions provided in the above embodiments, the display areas of the to-be-displayed data frame are classified as a first display area (in Figure 2b , a second display area (in Figure 2b , and a third display area (in Figure 2b ). The target data bit width of the display area classified as the first display area is determined as 8 bits, the target data bit width of the display area classified as the second display area is determined as 6 bits+FRC, and the target data bit width of the display area classified as the third display area is determined as 6 bits. It can be seen that the data bit width of the to-be-displayed data frame is adjusted to the target data bit width mixed with 6 bits, 6 bits+FRC and 8 bits.

[0115] In some specific examples, the five preset display areas are classified according to the multiple relationship between the average value of the difference and the third difference threshold. For example, when the average value of the difference of the display area is between one times the third difference threshold and two times the third difference threshold, it is determined that the display area is a third display area, that is, the luminance variation degree corresponding to the display area is small; when the average value of the difference of the display area is between two times the third difference threshold and three times the third difference threshold, it is determined that the display area is a second display area, that is, the luminance variation degree corresponding to the display area is general; and when the average value of the difference of the display area is greater than three times the third difference threshold, it is determined that the display area is a third display area, that is, the luminance variation degree corresponding to the display area is large.

[0116] In a feasible embodiment of the present application, according to the display parameter, the target data bit width for transmitting the to-be-displayed data frame is determined from a plurality of data bit widths including at least a first data bit width and a second data bit width, and further comprising:

[0117] The target data bit width corresponding to the odd-numbered column of pixel units in the previous to-be-displayed data frame of the adjacent two to-be-displayed data frames is determined as the first data bit width, and the target data bit width corresponding to the even-numbered column of pixel units is determined as the second data bit width;

[0118] The target data bit width corresponding to the odd-numbered column of pixel units in the latter one of the two adjacent frames of to-be-displayed data frames is determined as a second data bit width, and the target data bit width corresponding to the even-numbered column of pixel units is determined as a first data bit width.

[0119] Specifically, the target data bit width corresponding to different columns of pixel units in each frame of to-be-displayed data is configured respectively, so as to configure the display data transmission mode of each frame of to-be-displayed data. For the former frame of to-be-displayed data, the target data bit width corresponding to the odd-numbered column of pixel units is determined as a first data bit width, the display data corresponding to the odd-numbered column of pixel units is transmitted through the first data bit width, the target data bit width corresponding to the even-numbered column of pixel units is determined as a second data bit width, and the display data corresponding to the even-numbered column of pixel units is transmitted through the second data bit width; for the latter frame of to-be-displayed data, it is completely opposite.

[0120] As a specific example, refer to Figure 3a For the frame of to-be-displayed data Pixel m, the nth column of pixel units L(n) is transmitted by using 8-bit data bit width, and the (n+1)th column of pixel units L(n+1) is transmitted by using 6-bit data bit width; refer to Figure 3b For the frame of to-be-displayed data Pixel m+1, the nth column of pixel units L(n) is transmitted by using 6-bit data bit width, and the (n+1)th column of pixel units L(n+1) is transmitted by using 8-bit data bit width. Wherein, m is an integer greater than or equal to 1, and n is an integer greater than or equal to 1.

[0121] In the technical scheme provided in the above embodiment, two consecutive frames of to-be-displayed data frames are processed. For the former frame of to-be-displayed data, all odd-numbered columns of pixel units in the picture are transmitted by using a first data bit width (for example, 8-bit), and all even-numbered columns of pixel units are transmitted by using a second data bit width (for example, 6-bit).

[0122] Subsequently, for the latter frame of to-be-displayed data, the mode for the former frame of to-be-displayed data is completely reversed, all odd-numbered columns of pixel units are transmitted by using the second data bit width, and all even-numbered columns of pixel units are transmitted by using the first data bit width.

[0123] Due to the visual persistence effect of the human eye, this way of quickly alternating high and low bit width transmission columns between adjacent frames makes the picture quality perceived by the user in a macroscopic sense better than using low bit width transmission continuously, but the overall data transmission amount and power consumption are lower than using high bit width transmission continuously.

[0124] The technical scheme provided by the embodiment aims to achieve an equivalent display effect between a first data bit width and a second data bit width (for example, the first data bit width is 8 bits, the second data bit width is 6 bits, and the embodiment theoretically achieves a 7-bit effect) by cross using different data bit widths in the spatial and time dimensions, so as to reduce power consumption while ensuring good image quality.

[0125] In another possible embodiment of the present application, in order to simplify the data configuration mode and speed up the data processing speed, according to the display parameters, the target data bit width used for transmitting the to-be-displayed data frame is determined from a plurality of data bit widths including at least a first data bit width and a second data bit width.

[0126] The target data bit width corresponding to the previous to-be-displayed data frame in the two adjacent to-be-displayed data frames is determined as the first data bit width, and the target data bit width corresponding to the next to-be-displayed data frame in the two adjacent to-be-displayed data frames is determined as the second data bit width.

[0127] Specifically, compared with the above-mentioned embodiment of setting the target data bit width of the display data corresponding to different column pixel units in a to-be-displayed data frame, the embodiment only sets the target data bit width of the adjacent two to-be-displayed data frames. In this way, although the display effect of the embodiment may be weaker than that of the above-mentioned embodiment, the data configuration mode is simplified, the requirement for the data configuration device is lower, and the response can be faster.

[0128] As a specific example, refer to Figure 4a For the to-be-displayed data frame Pixel m, the data bit width of 8 bits is used for transmission; refer to Figure 4b For the to-be-displayed data frame Pixel m+1, the data bit width of 6 bits is used for transmission. Wherein, m is an integer greater than or equal to 1.

[0129] Generally, the above-mentioned embodiment of cross using different data bit widths to transmit the to-be-displayed data frame is suitable for high refresh rate display devices (for example, 240HZ or 360HZ).

[0130] In a possible embodiment of the present application, according to the display parameters, the base pixel driving voltage of each pixel unit in the to-be-displayed data frame is improved, including:

[0131] Respectively comparing the base pixel driving voltage of each pixel unit in the to-be-displayed data frame with the voltage threshold value;

[0132] In the case where the base pixel driving voltage of the pixel unit is less than or equal to the voltage threshold value, the compensation value of the pixel unit is determined as the first compensation value;

[0133] In a case where the base pixel driving voltage of the pixel unit is greater than the voltage threshold, the compensation value of the pixel unit is determined as a second compensation value; wherein the second compensation value is less than the first compensation value.

[0134] The base pixel driving voltage of each pixel unit in the to-be-displayed data frame is raised according to the compensation value of the pixel unit.

[0135] Specifically, the base pixel driving voltage of each pixel unit in the to-be-displayed data frame is compared with the voltage threshold respectively, and according to the comparison result, it is determined whether the display picture corresponding to the pixel unit is a bright display picture part or a dark display picture part, and based on such comparison result, the compensation value of each pixel unit is determined respectively.

[0136] In a case where the base pixel driving voltage of the pixel unit is less than or equal to the voltage threshold, it is indicated that the pixel unit corresponds to a relatively dark display picture part, and the compensation value of the pixel unit is determined as the first compensation value; in a case where the base pixel driving voltage of the pixel unit is greater than the voltage threshold, it is indicated that the pixel unit corresponds to a relatively bright display picture part, and the compensation value of the pixel unit is determined as the second compensation value, and the second compensation value is less than the first compensation value.

[0137] After the compensation value of each pixel unit is determined, the base pixel voltage of the pixel unit is raised according to the compensation value, and the adjustment of the pixel driving voltage of the to-be-displayed data frame is completed.

[0138] It can be seen that in the technical solution provided in the above embodiment, for the pixel unit corresponding to the relatively dark display picture part, more compensation is performed, the deflection angle of the liquid crystal molecules of the pixel unit is greatly increased, and the light transmittance of the pixel unit is greatly increased; for the pixel unit corresponding to the relatively bright display picture part, less compensation is performed, the deflection angle of the liquid crystal molecules of the pixel unit is slightly increased, and the light transmittance of the pixel unit is slightly increased. Overall, the overall light transmittance of the to-be-displayed data frame is increased, and the overall brightness of the to-be-displayed data frame is ensured.

[0139] Referring to Figure 5a , the initial to-be-displayed data frame is composed of 4x4 pixel units, wherein the base pixel driving voltage of the pixel units (hereinafter referred to as pixel unit A) located at the coordinates (2, 2), (2, 3), (3, 2) and (3, 3) is Y1, and the base pixel driving voltage of the pixel units (hereinafter referred to as pixel unit B) located at other coordinates is Y2. Assuming that the voltage threshold is Ys, and currently Y1>Ys>Y2, then the pixel unit A actually corresponds to a relatively bright pixel unit in the to-be-displayed data frame, and the pixel unit B actually corresponds to a relatively dark pixel unit in the to-be-displayed data frame, at this time, the brightness distribution of the to-be-displayed data frame can be determined.

[0140] After determining the luminance distribution of the data frame to be displayed, a compensation table corresponding to the current data frame to be displayed is determined according to the base pixel voltage of each pixel unit. Specifically, the compensation table records compensation values corresponding to the current data frame to be displayed, and the compensation values are arranged in corresponding coordinates according to the corresponding relationship with the pixel units. For example, in the current example, referring to Figure 5b , the compensation table is a 4x4 list, in which the cells at coordinates (2, 2), (2, 3), (3, 2), and (3, 3) are placed with compensation values corresponding to the pixel unit A, and the cells at other coordinates are placed with compensation values corresponding to the pixel unit B. Since the base driving voltages of the pixel unit A and the pixel unit B are Y1>Ys>Y2, it is determined that the compensation value of the pixel unit A is the second compensation value, denoted by k1 in Figure 5b , and the compensation value of the pixel unit B is the first compensation value, denoted by k2 in Figure 5b .

[0141] Based on the compensation table, the base pixel driving voltage of each pixel unit in the initial data frame to be displayed is adjusted to obtain an adjusted data frame to be displayed, and the overall light transmittance of the adjusted data frame to be displayed is increased. The pixel driving voltage of each pixel unit in the adjusted data frame to be displayed is as shown in Figure 5c .

[0143] The backlight luminance corresponding to the data frame to be displayed is reduced by a preset luminance value.

[0144] Specifically, the backlight luminance of the backlight module corresponding to the display panel is adjusted, and the backlight luminance of the backlight module is reduced by a preset luminance value as a whole when displaying the data frame to be displayed.
