[0065] The following explanations of the terms used in the embodiments of this application are provided to facilitate the reader's understanding.

[0066] 1. Color depth, also known as bit depth, is a unit used to represent the number of colors in a digital image, expressed in bits. Color depth is usually expressed as a power of 2, such as 3-bit, 6-bit, 8-bit, and 10-bit. Bits are a unit used to measure the amount of information; they represent the number of bits in a binary digit. In panel displays, it directly affects the number of grayscale levels and color depth. For example, n-bit can display 2^n grayscale levels. n The color depth that can be displayed is 2. n (R)X 2 n (G)X 2 n (B) = 2 3n The number of colors corresponding to each color depth is shown in Table 1 below.

[0067] Table 1

[0068] 2. Frame Rate Control (FRC) is a technique that achieves advanced grayscale control or simulates higher color depth by rapidly switching subpixel colors. On an LCD screen, each pixel consists of three subpixels: red (R), green (G), and blue (B) (sometimes also including white (W), forming RGBW). FRC technology utilizes the persistence of vision effect by rapidly switching the colors of these subpixels at different time periods, thus producing a visual effect with a higher color depth or grayscale level than the actual hardware supports. In other words, FRC technology can achieve an 8-bit effect on a 6-bit integrated circuit (IC).

[0069] For example, in FRC technology, by controlling the brightness of adjacent frames (temporal dithering) and the brightness of adjacent pixels (spatial dithering), the human eye can perceive brightness that the display screen cannot produce, thereby increasing the color depth of the display screen. Temporal dithering (FRC-3D) uses time as a dividing point, alternating between two adjacent gray levels to display the brightness between adjacent gray levels, thus increasing the color depth of the display. As shown in Figure 1, FRC technology controls the brightness of each frame (such as the first frame, second frame, third frame, and fourth frame), allowing the display screen to show multiple different gray levels.

[0070] As shown in Figure 2, spatial dithering (FRC-2D) uses space as a dividing point and alternately displays two adjacent gray levels, creating a brightness difference between the two gray levels in that area. This method can also increase color depth. A unit pixel can be understood as the smallest unit on a display screen capable of independently displaying a color.

[0071] In related technologies, liquid crystal displays (LCDs) can control the strength of the electric field within the liquid crystal cell by varying the voltage, thereby altering the alignment of liquid crystal molecules and controlling light transmission. Specifically, LCDs use voltage magnitude to control the angle at which the liquid crystals stand, thus controlling brightness. For example, as shown in Figure 3, taking the first frame (frame 1) and the second frame (frame 2) of a grayscale with R 0.25 as an example, the display of sub-pixels in this grayscale image is as follows:

[0072] In the first frame, the polarity of the bright pixels is "-". As shown in Figure 4, since the polarity of the bright pixels is negative, the reference voltage (Vcom) will be pulled in the negative direction, resulting in a shifted reference voltage. Therefore, in the first frame, the first voltage (Vframe1) applied to the liquid crystal will be relatively small.

[0073] In the second frame, all bright pixels have a positive polarity. Conversely, because the bright pixels in the second frame have positive polarity, this pushes the reference voltage (Vcom) in the positive direction (actually, this is relative to the negative pull in the first frame, so overall it increases the voltage on the liquid crystal). Therefore, in the second frame, the second voltage (Vframe2) applied to the liquid crystal is greater than the voltage in the first frame.

[0074] Because the polarities of the bright pixels in the first and second frames are opposite, the voltage applied to the liquid crystal is also different (second voltage > first voltage). This voltage difference causes the brightness of the second frame to be greater than that of the first frame. When this brightness change is perceived by the human eye due to the persistence of vision, it produces the phenomenon of screen flickering.

[0075] To address these issues, traditional FRC (Frame Recognition Control) technology adjusts and controls pixel polarity by inserting extra frames to achieve polarity balance across frames and prevent screen flicker. However, in a dual-gate drive architecture, traditional pixel dithering techniques typically use a single FRC table. This means that FRC can only adjust the polarity of one sub-pixel in the RGB spectrum to ensure that the polarity of the bright pixels is balanced in each frame. The polarity of other sub-pixels cannot be balanced across all bright pixels, leading to screen flicker and negatively impacting the user experience.

[0076] For example, as shown in Figure 5, taking the red sub-pixel (R) as an example, this figure presents the positive and negative polarities of bright pixels displayed in multiple frames (first frame, second frame, third frame, and fourth frame) at gray levels 0.25 and 0.5. The embodiments of this application do not limit the gray level aspect.

[0077] In Figure 5, the labels "positive" or "negative" indicate that the corresponding pixels are bright pixels. "Positive" indicates that the pixel polarity is positive, and "negative" indicates that the pixel polarity is negative. As shown in Figure 5, at a grayscale of 0.25, using a single FRC table, the number of bright pixels with positive polarity is 0 and the number of bright pixels with negative polarity is 4 in the first frame; 4 in the second frame and 0 in the third frame; 0 in the third frame and 4 in the fourth frame. Therefore, at a grayscale of 0.25, the positive and negative polarities of the bright pixels for the red sub-pixel (R) are balanced in every two frames.

[0078] Similarly, at a grayscale of 0.5, using a single FRC table, the number of positive polarity pixels displaying bright pixels in the first frame is 8, and the number of negative polarity pixels is 0; in the second frame, the number of positive polarity pixels displaying bright pixels is 0, and the number of negative polarity pixels is 8; in the third frame, the number of positive polarity pixels displaying bright pixels is 8, and the number of negative polarity pixels is 0; in the fourth frame, the number of positive polarity pixels displaying bright pixels is 0, and the number of negative polarity pixels is 8. This shows that at a grayscale of 0.5, the pixel polarity of the red sub-pixel (R) is the same as at a grayscale of 0.25, and the positive and negative polarities of the bright pixels are balanced between every two frames.

[0079] Figure 6 shows an example of a blue sub-pixel (B). The figure illustrates the positive and negative polarities of bright pixels displayed across multiple frames (first frame, second frame, third frame, and fourth frame) at gray levels 0.25 and 0.5. This application does not limit the scope of gray levels.

[0080] In Figure 6, the labels "positive" or "negative" indicate that the corresponding pixels are bright pixels. "Positive" indicates that the pixel polarity is positive, and "negative" indicates that the pixel polarity is negative. As shown in Figure 6, at a grayscale of 0.25, using a single FRC table, the number of bright pixels with positive polarity is 4 and the number of bright pixels with negative polarity is 0 in the first frame; 0 and 4 in the second frame; 4 and 0 in the third frame; and 0 and 4 in the fourth frame. Therefore, at a grayscale of 0.25, the positive and negative polarities of the bright pixels for the blue sub-pixel (B) are balanced in every two frames.

[0081] Similarly, at a grayscale of 0.5, using a single FRC table, the number of positive polarities of bright pixels in the first frame is 0, and the number of negative polarities is 8; in the second frame, the number of positive polarities of bright pixels is 8, and the number of negative polarities is 0; in the third frame, the number of positive polarities of bright pixels is 0, and the number of negative polarities is 8; in the fourth frame, the number of positive polarities of bright pixels is 8, and the number of negative polarities is 0. Thus, at a grayscale of 0.5, the pixel polarity of the blue sub-pixel (B) is the same as at a grayscale of 0.25, ensuring a balance between the positive and negative polarities of bright pixels in every two frames.

[0082] Figure 7 illustrates the green sub-pixel (G) as an example. The figure shows the positive and negative polarities of bright pixels displayed across multiple frames (first frame, second frame, third frame, and fourth frame) at gray levels 0.25 and 0.5. This application does not limit the gray level aspect in its embodiments.

[0083] In Figure 7, the labels "positive" or "negative" indicate that the corresponding pixels are bright pixels. "Positive" indicates that the pixel polarity is positive, and "negative" indicates that the pixel polarity is negative. As shown in Figure 7, at a grayscale of 0.25, using a single FRC table, the number of bright pixels in the first frame is 2 for both positive and negative polarities; the second frame is the same; the third frame is the same; and the fourth frame is the same. Therefore, at a grayscale of 0.25, the positive and negative polarities of the bright pixels in each frame of the green sub-pixel (G) are balanced.

[0084] Similarly, at a grayscale of 0.5, using a single FRC table, the number of positive and negative polarities of the bright pixels displayed in the first frame is 4; the number of positive and negative polarities of the bright pixels displayed in the second frame is 4; the number of positive and negative polarities of the bright pixels displayed in the third frame is 4; and the number of positive and negative polarities of the bright pixels displayed in the fourth frame is 4. Thus, it can be seen that at a grayscale of 0.5, the pixel polarity of the green sub-pixel (G) is the same as at a grayscale of 0.25, and the positive and negative polarities of the bright pixels displayed in each frame are balanced.

[0085] In summary, because RGB uses the same FRC table, only the green subpixel (G) can achieve a balance of positive and negative polarities for the bright pixels displayed in each frame, while the red subpixel (R) and blue subpixel (B) can only achieve a balance of positive and negative polarities for the bright pixels displayed between every two frames. This results in a severe flickering problem for the red subpixel (R) and blue subpixel (B).

[0086] In view of this, the present application provides a display device, which includes: a display panel, a plurality of pairs of gate lines, a plurality of data lines and a plurality of sub-pixels, the plurality of pairs of gate lines and the plurality of data lines perpendicularly intersecting to define a plurality of display units arranged in an array, each pair of adjacent sub-pixels being disposed in a display unit, and each data line alternately connecting the display units on both sides thereof.

[0087] The display device can be used to display multiple grayscale images. When the display device displays the second grayscale image, some sub-pixels of multiple sub-pixels are lit up. At this time, the display panel displays multiple frames. Each sub-pixel in each frame corresponds to a mapping relationship. The mapping relationship is used to determine the corresponding lit sub-pixels in that frame. The number of positive polarity sub-pixels in the lit corresponding sub-pixels is equal to the number of negative polarity sub-pixels. This ensures that the multiple lit pixels of each sub-pixel maintain polarity balance in each frame, thereby avoiding flickering problems between different sub-pixels. It should be understood that polarity balance means that the number of lit sub-pixels representing positive polarity is equal to the number of pixels representing negative polarity.

[0088] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0089] Figure 8 shows a structural diagram of a display device 800 provided in an embodiment of this application. The display device 800 can be a terminal device with a display panel, such as a television set. The display device 800 may include a display panel 801, at least one processor 802, and a transceiver 803, and may also include a memory 804. The processor 802, memory 804, and transceiver 803 can be connected via communication lines.

[0090] In this embodiment of the application, the display panel 801 is used to display multiple different grayscale images.

[0091] In this embodiment, the processor 802 can be a chip. Chips can include five main categories: logic chips, memory chips, sensor chips, power chips, and communication chips. Processors primarily handle specific computational and control tasks within the system, such as microcontroller units (MCUs), central processing units (CPUs), graphics processing units (GPUs), and neural processing units (NPUs). Memory chips primarily handle data storage within the system, as well as some memory controller chips, such as dynamic random access memory (DRAM), static random access memory (SRAM), and flash memory (Flash). Sensor chips primarily handle information acquisition, presentation, and interaction within the system, such as input / output devices and some signal processing chips. Communication chips (wired and wireless) are those that primarily perform communication functions within a system. Examples include Ethernet chips, switching chips, WAN and LAN chips, point-to-point and ad hoc network chips, as well as auxiliary communication devices such as filters, amplifiers, and power supplies. Commonly known chips in this category include wireless fidelity (WiFi), Bluetooth, 5G baseband, GPS, narrowband Internet of Things (NB-IoT), network interface cards (NICs), and switches.

[0092] The communication line may include a path for transmitting information between the aforementioned components.

[0093] The memory 804 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium capable of including or storing desired program code in the form of instructions or data structures and accessible by a computer, but not limited thereto.

[0094] In one possible design, the memory 804 can exist independently of the processor 802, meaning the memory 804 can be an external memory of the processor 802. In this case, the memory 804 can be connected to the processor 802 via a communication line to store execution instructions or application code, and its execution is controlled by the processor 802 to implement the network quality determination method provided in the following embodiments of this application. In another possible design, the memory 804 can also be integrated with the processor 802, meaning the memory 804 can be an internal memory of the processor 802. For example, the memory 804 can be a cache, used to temporarily store some data and instruction information.

[0095] As one possible implementation, processor 802 may include one or more CPUs.

[0096] It should be noted that the display devices described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of display devices and the emergence of other display devices, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0097] As shown in Figure 9, Figure 9 is a structural diagram of a display panel 801 provided in an embodiment of this application. The display panel 801 can be a dual-gate array substrate. The display panel 801 can include multiple pairs of gate lines 901, multiple data lines 902, and multiple sub-pixels 903. Among them, the multiple pairs of gate lines and the multiple data lines intersect perpendicularly to define multiple display units 904 arranged in an array. Each pair of adjacent sub-pixels 903 is disposed in a display unit 904, and each data line 902 alternately connects the display units 904 on both sides of it.

[0098] In some embodiments, multiple display units are arranged in N rows and M columns; M+1 data lines are arranged sequentially along the row direction.

[0099] For example, multiple display units are arranged in 4 rows and 6 columns. Accordingly, 7 data lines are arranged sequentially along the row direction. For example, the 7 data lines include D1, D2, D3, D4, D5, D6, and D7.

[0100] In some embodiments, except for the first data line and the last data line, the (i+1)th data line is connected to the even-numbered display unit in the i-th column of display units and to the odd-numbered display unit in the (i+1)-th column of display units.

[0101] Where 1≤i≤M-1.

[0102] For example, take D2 (data cable) as an example. D2 (data cable) is connected to the second and fourth display units in the first column of display units, and to the first and third display units in the second column of display units.

[0103] In other words, as shown in Figure 9, D2 (data cable) is connected to the first display unit in the second column of the display unit, then to the second display unit in the first column of the display unit, then to the third display unit in the second column of the display unit, and then to the fourth display unit in the first column of the display unit.

[0104] In some embodiments, the first data line is connected to the odd-numbered display unit in the first column of display units, and the last data line is connected to the even-numbered display unit in the M-th column of display units.

[0105] For example, D1 (data line) is connected to the first and third display units in the first column of display units, and D7 (data line) is connected to the second and fourth display units in the second column of display units.

[0106] In some embodiments, the first data line is connected to the odd-numbered display unit in the first column of display units and to the even-numbered display unit in the M-th column of display units. Alternatively, the last data line is connected to the odd-numbered display unit in the first column of display units and to the even-numbered display unit in the M-th column of display units.

[0107] For example, taking M as 6. D1 (data cable) is connected to the first display unit in the first column of display units, then to the second display unit in the sixth column of display units, then to the third display unit in the first column of display units, and then to the fourth display unit in the sixth column of display units.

[0108] Similarly, D7 (data cable) can be connected to the first display unit in the first column of display units, then to the second display unit in the sixth column of display units, then to the third display unit in the first column of display units, and then to the fourth display unit in the sixth column of display units.

[0109] In some other embodiments, except for the first data line and the last data line, the (i+1)th data line is connected to the odd-numbered display unit in the i-th column of display units and to the even-numbered display unit in the (i+1)-th column of display units.

[0110] Where 1≤i≤M-1.

[0111] For example, taking the D5 data cable as an example, the D5 (data cable) is connected to the first and third display units in the fourth column of display units, and to the second and fourth display units in the fifth column of display units.

[0112] In other words, after D5 (data cable) is connected to the first display unit in the 4th column, it is connected to the second display unit in the 5th column, then to the third display unit in the 4th column, and then to the fourth display unit in the 5th column.

[0113] In some other embodiments, the first data line is connected to the even-numbered display unit in the first column of display units, and the last data line is connected to the odd-numbered display unit in the M-th column of display units.

[0114] For example, D1 (data line) is connected to the second and fourth display units in the first column of display units, and D7 (data line) is connected to the first and third display units in the second column of display units.

[0115] In some embodiments, the last data line is connected to the odd-numbered display unit in the M-th column of display units and to the even-numbered display unit in the first column of display units.

[0116] For example, taking M as 6. D7 (data cable) can be connected to the first display unit in the 6th column of the display unit, then to the second display unit in the 1st column of the display unit, then to the third display unit in the 6th column of the display unit, and then to the fourth display unit in the 1st column of the display unit.

[0117] In some embodiments, the plurality of sub-pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel; the plurality of display units includes a first type of display unit, a second type of display unit, and a third type of display unit, wherein the first type of display unit includes a first sub-pixel and a second sub-pixel, the second type of display unit includes a first sub-pixel and a third sub-pixel, and the third type of display unit includes a second sub-pixel and a third sub-pixel.

[0118] For example, as shown in Figure 9. The first sub-pixel can be a red sub-pixel, the second sub-pixel can be a green sub-pixel, and the third sub-pixel can be a blue sub-pixel; the first type of display unit can include red sub-pixels and green sub-pixels, the second type of display unit can include blue sub-pixels and red sub-pixels, and the third type of display unit can include green sub-pixels and blue sub-pixels.

[0119] In some embodiments, multiple pairs of gate lines are arranged sequentially along the column direction. Each row of display units is connected to a pair of gate lines, and one sub-pixel in each display unit is connected to one of the gate lines in the pair, while the other sub-pixel is connected to the other gate line in the pair.

[0120] Referring to Figure 9, multiple pairs of gate lines include G1, G2, G3, G4, G5, G6, G7, G8, and G9. Assuming G1 and G2 are a pair of gate lines, let's take G1, G2, and the first row of display units as an example. The first row of display units is connected to G1 and G2. The first display unit in the first row can be a first-type display unit, in which the red sub-pixel is connected to G2 (gate line), and the green sub-pixel is connected to G1 (gate line).

[0121] The second display unit in the first row of display units can be a second type of display unit, in which the blue sub-pixel is connected to G1 (gate line) and the red sub-pixel is connected to G2 (gate line).

[0122] The third display unit in the first row of display units can be a third type of display unit, in which the green sub-pixel is connected to G1 (gate line) and the blue sub-pixel is connected to G2 (gate line).

[0123] In some embodiments, multiple display units in one column of display units connected by the data line are of the same type, and multiple display units in another column of display units connected by the data line are of the same type except for those of the same type.

[0124] For example, multiple display units in one column of display units connected by the data cable are first-type display units, and multiple display units in another column of display units connected by the data cable are second-type or third-type display units.

[0125] In one scenario, take D2 (data cable) as an example. D2 (data cable) is connected to the second and fourth display units in the first column of display units, and the second and fourth display units in the first column of display units are both type 1 display units.

[0126] At the same time, D2 (data cable) is also connected to the first and third display units in the second column of display units, and the first and third display units in the second column of display units are both second-type display units.

[0127] In some embodiments, the sub-pixels of multiple display units connected by any one data line have the same polarity.

[0128] For example, referring to Figure 9, take D2 (data line) as an example. The polarity of the sub-pixels of the second and fourth display units in the first column of display units connected to D2 (data line), as well as the first and third display units in the second column of display units connected to D2 (data line), are all negative.

[0129] For example, referring to Figure 9, take D3 (data line) as an example. The polarity of the sub-pixels of the second and fourth display units in the second column of display units connected to D3 (data line) and the first and third display units in the third column of display units connected to D3 (data line) are all positive.

[0130] It should be understood that the voltage of the sub-pixel electrode has both positive and negative polarities corresponding to the voltage of the common electrode.

[0131] In some embodiments, the two sub-pixels included in each display unit have the same polarity.

[0132] For example, referring to Figure 9, taking the first row of display units as an example. The red and green sub-pixels included in the first display unit of the first row of display units are both positive; the blue and red sub-pixels included in the second display unit of the first row of display units are both negative; and the green and blue sub-pixels included in the third display unit of the first row of display units are both positive.

[0133] In some embodiments, adjacent display units have different polarities.

[0134] For example, referring to Figure 9, taking the first row of display units as an example. Since the red and green sub-pixels included in the first display unit are both positive, the blue and red sub-pixels included in the second display unit in the first row are both negative, and the green and blue sub-pixels included in the third display unit in the first row are both positive, it can be determined that the polarities of two adjacent display units are different.

[0135] The above is a detailed description of the display panel provided in the embodiments of this application.

[0136] The following is a detailed overview of the pre-defined mapping relationships applied to the aforementioned display panel.

[0137] In some embodiments, the display panel is used to display multiple different grayscale images, in which multiple sub-pixels are lit up in the first grayscale image; and in the second grayscale image, some sub-pixels of the multiple sub-pixels are lit up.

[0138] It should be understood that in order to achieve an 8-bit display effect on a 6-bit integrated circuit (IC), FRC technology can insert different grayscale frames between two grayscale frames. For example, 8-bit has 256 grayscale levels, while 6-bit has 64 grayscale levels, such as L0-L64. FRC technology can increase grayscale by interpolating frames, such as inserting 3 grayscale levels between each grayscale frame (L0-L1, L1-L2, ..., L63-L64), resulting in 64*3+64=256, thus achieving an 8-bit display effect.

[0139] For example, the applicable scenario of this application embodiment may be that, during the testing of the display panel, the display panel displays a target image, and in the first state (full white screen) of the target image, all sub-pixels are lit up, that is, the display panel displays the first grayscale screen of the target image.

[0140] Furthermore, the grayscale brightness of the target image can be adjusted (e.g., adjusted to L0.25, L0.5, or L0.75 grayscale). Since the grayscale brightness of the adjusted target image is lower than that of the original target image, some sub-pixels in the target image will be turned off. This embodiment of the application can illuminate sub-pixels in different grayscale images through a pre-set mapping relationship, ensuring that the number of positive and negative sub-pixels among the illuminated sub-pixels is equal, thereby avoiding the problem of target image flickering.

[0141] As shown in Figure 10, taking the insertion of L0.25, L0.5, and L0.75 grayscale images between L0 and L1 grayscale images as an example, the first grayscale image can be the L1 grayscale image. In the L1 grayscale image, multiple sub-pixels are lit, that is, all sub-pixels in the L1 grayscale image are lit.

[0142] The second grayscale image includes a first sub-grayscale image, a second sub-grayscale image, and a third sub-grayscale image. The first sub-grayscale image can be a grayscale image of L0.25, the second sub-grayscale image can be a grayscale image of L0.5, and the third sub-grayscale image can be a grayscale image of L0.75. It should be noted that the grayscale values ​​of the first, second, and third sub-grayscale images, along with the first grayscale image, form an arithmetic sequence.

[0143] In an L0.25 grayscale image, one-quarter of the sub-pixels of multiple sub-pixels are illuminated; in an L0.5 grayscale image, one-half of the sub-pixels of multiple sub-pixels are illuminated; and in an L0.75 grayscale image, three-quarters of the sub-pixels of multiple sub-pixels are illuminated.

[0144] It should be understood that the sub-pixels marked with "+" and "-" in Figure 10 indicate that the corresponding sub-pixels are lit up.

[0145] In some embodiments, when the display panel displays a second grayscale image, the display panel displays multiple frames, and each sub-pixel in each frame corresponds to a mapping relationship. The mapping relationship is used to determine the corresponding sub-pixel that is lit in that frame, and the number of positive polarity sub-pixels in the lit corresponding sub-pixels is equal to the number of negative polarity sub-pixels.

[0146] For example, when the display panel displays any one of the grayscale images L0.25, L0.5, and L0.75, the display panel can display multiple frames in a loop, with each sub-pixel corresponding to a mapping relationship. Figure 11 shows the mapping relationship between different grayscale images (L0.25, L0.5, and L0.75) for the red sub-pixel. These multiple frames include, but are not limited to, the first frame, the second frame, the third frame, and the fourth frame.

[0147] As shown in Figure 11, the red sub-pixels marked with "+" and "-" are the lit red sub-pixels. "+" indicates that the polarity of the lit red sub-pixel is positive, and "-" indicates that the polarity of the lit red sub-pixel is negative. The red sub-pixels marked with "0" are not lit.

[0148] Taking the L0.25 grayscale image of the first frame as an example, the red sub-pixels can be lit according to the mapping relationship in this frame. As shown in Figure 11, the polarity of the lit red sub-pixels in the first two rows is positive, and the polarity of the lit red sub-pixels in the last two rows is negative. The number of lit red sub-pixels with positive polarity is 2 (2 positive polarity) and the number of lit red sub-pixels with negative polarity is 2 (2 negative polarity). This balances the positive and negative polarities of the corresponding lit sub-pixels, that is, the number of positive polarity sub-pixels is equal to the number of negative polarity sub-pixels.

[0149] It should be understood that the polarity of each sub-pixel is predetermined by the display panel (dual grid array substrate).

[0150] Figure 12 shows the mapping relationship between different grayscale images (L0.25 grayscale image, L0.5 grayscale image, L0.75 grayscale image) of the green sub-pixel. Among them, multiple frames include, but are not limited to, the first frame, the second frame, the third frame, and the fourth frame.

[0151] As shown in Figure 12, the green sub-pixels marked with "+" and "-" are the lit green sub-pixels. "+" indicates that the polarity of the lit green sub-pixel is positive, and "-" indicates that the polarity of the lit green sub-pixel is negative. The green sub-pixels marked with "0" are not lit.

[0152] Taking the L0.25 grayscale image of the first frame as an example, the green sub-pixels can be lit according to the mapping relationship in this frame. As shown in Figure 12, the polarity of the lit green sub-pixels in the first two rows is positive, and the polarity of the lit green sub-pixels in the last two rows is negative. The number of lit green sub-pixels with positive polarity is 2 (2 positive polarity) and the number of lit green sub-pixels with negative polarity is 2 (2 negative polarity). This balances the positive and negative polarities of the corresponding lit sub-pixels, that is, the number of positive polarity sub-pixels is equal to the number of negative polarity sub-pixels.

[0153] Figure 13 shows the mapping relationship between different grayscale images (L0.25 grayscale image, L0.5 grayscale image, L0.75 grayscale image) of the blue sub-pixel. Among them, multiple frames include, but are not limited to, the first frame, the second frame, the third frame, and the fourth frame.

[0154] As shown in Figure 13, the blue sub-pixels marked with "+" and "-" are the lit blue sub-pixels. "+" indicates that the polarity of the lit blue sub-pixel is positive, and "-" indicates that the polarity of the lit blue sub-pixel is negative. The blue sub-pixels marked with "0" are not lit.

[0155] Taking the L0.25 grayscale image of the first frame as an example, the blue sub-pixels can be lit according to the mapping relationship in this frame. As shown in Figure 13, the polarity of the lit blue sub-pixels in the first two rows is positive, and the polarity of the lit blue sub-pixels in the last two rows is negative. The number of lit blue sub-pixels with positive polarity is 2 (2 positive polarity) and the number of lit blue sub-pixels with negative polarity is 2 (2 negative polarity). This balances the positive and negative polarities of the corresponding lit sub-pixels, that is, the number of positive polarity sub-pixels is equal to the number of negative polarity sub-pixels.

[0156] It should be understood that the embodiments of this application can ensure the polarity balance of the corresponding sub-pixels that are lit in the multi-frame display by using the above-described mapping relationship between different sub-pixels, thereby avoiding the problem of screen flickering.

[0157] In some embodiments, the display device includes a memory for storing a predefined mapping relationship. The predefined mapping relationship includes multiple sub-mapping relationships, each of which is used to characterize the position information of multiple lit sub-pixels in each frame, and each frame of each sub-mapping relationship includes four rows of sub-pixels.

[0158] In this context, one sub-mapping relationship corresponds to one grayscale image. For example, multiple sub-mapping relationships include a first sub-mapping relationship, a second sub-mapping relationship, and a third sub-mapping relationship; the first sub-mapping relationship corresponds to the first sub-grayscale image, the second sub-mapping relationship corresponds to the second sub-grayscale image, and the third sub-mapping relationship corresponds to the third sub-grayscale image.

[0159] For example, as shown in FIG14, a pre-defined mapping relationship is provided in an embodiment of this application. In this pre-defined mapping relationship, the sub-pixels marked with "+" and "-" are the lit sub-pixels. The position information of each lit sub-pixel in each frame (e.g., the first frame, the second frame, the third frame, and the fourth frame) can be determined through this pre-defined mapping relationship.

[0160] Among them, the L0.25 grayscale image (the first sub-grayscale image) corresponds to a sub-mapping relationship, such as the first sub-mapping relationship; the L0.5 grayscale image (the second sub-grayscale image) corresponds to a sub-mapping relationship, such as the second sub-mapping relationship; the L0.75 grayscale image (the third sub-grayscale image) corresponds to a sub-mapping relationship, such as the third sub-mapping relationship; and each frame of each sub-mapping relationship includes four rows of sub-pixels.

[0161] In some embodiments, multiple sub-pixels in each row of sub-pixels are arranged periodically with the first sub-pixel, the second sub-pixel, and the third sub-pixel as cyclic units, and multiple sub-pixels in a column of sub-pixels are of the same seed pixel.

[0162] The first sub-pixel can be a red sub-pixel; the second sub-pixel can be a green sub-pixel; and the third sub-pixel can be a blue sub-pixel.

[0163] For example, referring to Figure 14, consider the fourth frame of the third sub-mapping relationship. The fourth frame of this sub-mapping relationship includes, but is not limited to, loop unit a and loop unit b. Loop unit a sequentially includes red sub-pixels, green sub-pixels, and blue sub-pixels. It should be understood that, since the loop units are arranged periodically, loop unit b also sequentially includes red sub-pixels, green sub-pixels, and blue sub-pixels.

[0164] At the same time, all columns containing red sub-pixels are red, all columns containing green sub-pixels are green, and all columns containing blue sub-pixels are blue.

[0165] It should be understood that this pre-defined mapping relationship can be obtained by combining Figures 11-13.

[0166] In some embodiments, in the first sub-mapping relationship, the first two rows of sub-pixels illuminate the even-numbered sub-pixels, and the last two rows of sub-pixels illuminate the odd-numbered sub-pixels; or, the first two rows of sub-pixels illuminate the odd-numbered sub-pixels, and the last two rows of sub-pixels illuminate the even-numbered sub-pixels.

[0167] For example, taking the first frame of the first sub-mapping relationship as an example; the first two rows of subpixels illuminate the odd-numbered subpixels, and the last two rows of subpixels illuminate the even-numbered subpixels. For example, as shown in Figure 15, the first sub-mapping relationship corresponds to a grayscale image of L0.25. Since each frame includes four rows of subpixels, in the first frame, the first row of subpixels illuminates the first, fifth, and ninth subpixels; the second row of subpixels illuminates the third, seventh, and eleventh subpixels; the third row of subpixels illuminates the fourth, eighth, and twelfth subpixels; and the fourth row of subpixels illuminates the second, sixth, and tenth subpixels.

[0168] Because the second frame of the first sub-mapping relationship, like the first frame, has the same configuration where the odd-numbered subpixels in the first two rows are lit, and the even-numbered subpixels in the last two rows are lit, this will not be elaborated further here. It should be understood that the positions of the lit subpixels in the second frame of the first sub-mapping relationship are not the same as in the first frame.

[0169] Taking the third frame of the first sub-mapping relationship as an example; the first two rows of sub-pixels illuminate the even-numbered sub-pixels, and the last two rows of sub-pixels illuminate the odd-numbered sub-pixels. For example, as shown in Figure 15, in the third frame, the first row of sub-pixels illuminates the second, sixth, and tenth sub-pixels; the second row of sub-pixels illuminates the fourth, eighth, and twelfth sub-pixels; the third row of sub-pixels illuminates the third, seventh, and eleventh sub-pixels; and the fourth row of sub-pixels illuminates the first, fifth, and ninth sub-pixels.

[0170] Since the fourth frame of the first sub-mapping relationship is the same as the third frame, where the even-numbered subpixels in the first two rows are lit and the odd-numbered subpixels in the last two rows are lit, this will not be elaborated further here. It should be understood that the positions of the lit subpixels in the fourth frame of the first sub-mapping relationship are not the same as those in the third frame.

[0171] It should be noted that the positions of the illuminated sub-pixels are different in each frame from the first to the fourth frame. Furthermore, referring to Figure 15, it can be determined that in the first sub-mapping relationship, the number of positive and negative sub-pixels illuminated in each frame is the same. For example, in the first frame, the number of both positive and negative sub-pixels is 6.

[0172] It is understandable that the above examples of the overall mapping rules based on the first sub-mapping relationship do not distinguish between different sub-pixels. The following examples of mapping rules based on the first sub-mapping relationship and different sub-pixels are provided.

[0173] Another example, as shown in Figure 15, clearly distinguishes three different sub-pixels (red sub-pixel, green sub-pixel, and blue sub-pixel) in the first sub-mapping relationship.

[0174] It should be understood that each row of sub-pixels in this sub-mapping relationship includes four red sub-pixels, four green sub-pixels, and four blue sub-pixels. Since the first sub-mapping relationship corresponds to the L0.25 grayscale image, each row of red, green, and blue sub-pixels will light up one corresponding sub-pixel.

[0175] Specifically, the position of each lit sub-pixel in different frames can be seen in Table 2 below.

[0176] Table 2

[0177] In the table, R represents red subpixels, G represents green subpixels, and B represents blue subpixels; 0.25 represents L0.25 grayscale image.

[0178] The following explanation of Table 2 will use the first frame as an example:

[0179] For the red sub-pixels in the first frame, the first two rows of red sub-pixels illuminate the odd-numbered red sub-pixels, and the last two rows of red sub-pixels illuminate the even-numbered red sub-pixels. For example, the first row illuminates the first red sub-pixel (corresponding to "1" in R / 0.25 of the first frame in Table 2), the second row illuminates the third red sub-pixel (corresponding to "3" in R / 0.25 of the first frame in Table 2), the third row illuminates the second red sub-pixel (corresponding to "2" in R / 0.25 of the first frame in Table 2), and the fourth row illuminates the fourth red sub-pixel (corresponding to "4" in R / 0.25 of the first frame in Table 2).

[0180] At the same time, it can be determined that the number of positive red sub-pixels and the number of negative red sub-pixels in the illuminated red sub-pixels are equal. For example, in the first frame, the number of positive red sub-pixels and the number of negative red sub-pixels in the illuminated red sub-pixels are both 2.

[0181] For the green sub-pixels in the first frame, the first two rows of green sub-pixels illuminate the even-numbered green sub-pixels, and the last two rows of green sub-pixels illuminate the odd-numbered green sub-pixels. For example, the first row illuminates the second green sub-pixel (corresponding to "2" in G / 0.25 of the first frame in Table 2), the second row illuminates the fourth green sub-pixel (corresponding to "4" in G / 0.25 of the first frame in Table 2), the third row illuminates the third green sub-pixel (corresponding to "3" in G / 0.25 of the first frame in Table 2), and the fourth row illuminates the first green sub-pixel (corresponding to "1" in G / 0.25 of the first frame in Table 2).

[0182] At the same time, it can be determined that the number of positive green sub-pixels and the number of negative green sub-pixels in the illuminated green sub-pixels are equal. For example, in the first frame, the number of positive green sub-pixels and the number of negative green sub-pixels in the illuminated green sub-pixels are both 2.

[0183] For the blue sub-pixels in the first frame, the first two rows of blue sub-pixels illuminate the odd-numbered blue sub-pixels, and the last two rows of blue sub-pixels illuminate the even-numbered blue sub-pixels. For example, the first row illuminates the third blue sub-pixel (corresponding to "3" in B / 0.25 of the first frame in Table 2), the second row illuminates the first blue sub-pixel (corresponding to "1" in B / 0.25 of the first frame in Table 2), the third row illuminates the fourth blue sub-pixel (corresponding to "4" in B / 0.25 of the first frame in Table 2), and the fourth row illuminates the second blue sub-pixel (corresponding to "2" in B / 0.25 of the first frame in Table 2).

[0184] At the same time, it can be determined that the number of positive blue sub-pixels and the number of negative blue sub-pixels in the illuminated blue sub-pixels are equal. For example, in the first frame, the number of positive blue sub-pixels and the number of negative blue sub-pixels in the illuminated blue sub-pixels are both 2.

[0185] As can be seen from Table 2 above, in the first frame and the second frame, for the first sub-pixel and the third sub-pixel, the first two rows of sub-pixels illuminate the odd-numbered sub-pixels, and the last two rows of sub-pixels illuminate the even-numbered sub-pixels; for the second sub-pixel, the first two rows of sub-pixels illuminate the even-numbered sub-pixels, and the last two rows of sub-pixels illuminate the odd-numbered sub-pixels.

[0186] In other words, in the first frame, for red sub-pixels, the first two rows of sub-pixels illuminate the first and third sub-pixels (i.e., 1 and 3 corresponding to R / 0.25 in the first frame of Table 2), and the last two rows of sub-pixels illuminate the second and fourth sub-pixels (i.e., 2 and 4 corresponding to R / 0.25 in the first frame of Table 2); in the second frame, for red sub-pixels, the first two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 3 and 1 corresponding to R / 0.25 in the second frame of Table 2), and the last two rows of sub-pixels illuminate the fourth and second sub-pixels (i.e., 4 and 2 corresponding to R / 0.25 in the second frame of Table 2).

[0187] Accordingly, in the first frame, for blue sub-pixels, the first two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 3 1 corresponding to B / 0.25 in the first frame of Table 2), and the last two rows of sub-pixels illuminate the second and fourth sub-pixels (i.e., 4 2 corresponding to B / 0.25 in the first frame of Table 2); in the second frame, for blue sub-pixels, the first two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 1 3 corresponding to B / 0.25 in the second frame of Table 2), and the last two rows of sub-pixels illuminate the fourth and second sub-pixels (i.e., 2 4 corresponding to B / 0.25 in the second frame of Table 2).

[0188] In the third and fourth frames, for the first and third sub-pixels, the even-numbered sub-pixels in the first two rows are illuminated, and the odd-numbered sub-pixels in the last two rows are illuminated; for the second sub-pixel, the odd-numbered sub-pixels in the first two rows are illuminated, and the even-numbered sub-pixels in the last two rows are illuminated.

[0189] In other words, in the third frame, for the red sub-pixel, the first two rows of sub-pixels illuminate the fourth and second sub-pixels (i.e., 4 2 corresponding to R / 0.25 in the third frame of Table 2), and the last two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 3 1 corresponding to R / 0.25 in the third frame of Table 2); in the fourth frame, for the red sub-pixel, the first two rows of sub-pixels illuminate the second and fourth sub-pixels (i.e., 2 4 corresponding to R / 0.25 in the fourth frame of Table 2), and the last two rows of sub-pixels illuminate the first and third sub-pixels (i.e., 1 3 corresponding to R / 0.25 in the fourth frame of Table 2).

[0190] Correspondingly, in the third frame, for blue sub-pixels, the first two rows of sub-pixels illuminate the second and fourth sub-pixels (i.e., 2 4 corresponding to B / 0.25 in the third frame of Table 2), and the last two rows of sub-pixels illuminate the first and third sub-pixels (i.e., 1 3 corresponding to B / 0.25 in the third frame of Table 2); in the fourth frame, for blue sub-pixels, the first two rows of sub-pixels illuminate the fourth and second sub-pixels (i.e., 4 2 corresponding to B / 0.25 in the fourth frame of Table 2), and the last two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 3 1 corresponding to B / 0.25 in the fourth frame of Table 2).

[0191] Specifically, the position of each lit sub-pixel in different frames can also be seen in Table 3 below.

[0192] Table 3

[0193] In the table, R represents red subpixels, G represents green subpixels, and B represents blue subpixels; 0.25 represents L0.25 grayscale image.

[0194] As can be seen from Table 3 above, in the first frame and the second frame, for the first sub-pixel and the third sub-pixel, the sub-pixels in the first two rows are lit up in the even-numbered positions, and the sub-pixels in the last two rows are lit up in the odd-numbered positions; for the second sub-pixel, the sub-pixels in the first two rows are lit up in the odd-numbered positions, and the sub-pixels in the last two rows are lit up in the even-numbered positions.

[0195] In other words, in the first frame, for red sub-pixels, the first two rows of sub-pixels illuminate the fourth and second sub-pixels (i.e., 4 2 corresponding to R / 0.25 in the first frame of Table 3), and the last two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 3 1 corresponding to R / 0.25 in the first frame of Table 3); in the second frame, for red sub-pixels, the first two rows of sub-pixels illuminate the second and fourth sub-pixels (i.e., 2 4 corresponding to R / 0.25 in the second frame of Table 3), and the last two rows of sub-pixels illuminate the first and third sub-pixels (i.e., 1 3 corresponding to R / 0.25 in the second frame of Table 3).

[0196] Accordingly, in the first frame, for blue sub-pixels, the first two rows of sub-pixels illuminate the second and fourth sub-pixels (i.e., 2 4 corresponding to B / 0.25 in the first frame of Table 3), and the last two rows of sub-pixels illuminate the first and third sub-pixels (i.e., 1 3 corresponding to B / 0.25 in the first frame of Table 3); in the second frame, for blue sub-pixels, the first two rows of sub-pixels illuminate the fourth and second sub-pixels (i.e., 4 2 corresponding to B / 0.25 in the second frame of Table 3), and the last two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 3 1 corresponding to B / 0.25 in the second frame of Table 3).

[0197] In the third and fourth frames, for the first and third sub-pixels, the first two rows of sub-pixels illuminate the odd-numbered sub-pixels, and the last two rows of sub-pixels illuminate the even-numbered sub-pixels; for the second sub-pixel, the first two rows of sub-pixels illuminate the even-numbered sub-pixels, and the last two rows of sub-pixels illuminate the odd-numbered sub-pixels.

[0198] In other words, in the third frame, for the red sub-pixel, the first two rows of sub-pixels illuminate the first and third sub-pixels (i.e., 1 and 3 corresponding to R / 0.25 in Table 3), and the last two rows of sub-pixels illuminate the second and fourth sub-pixels (i.e., 2 and 4 corresponding to R / 0.25 in Table 3); in the fourth frame, for the red sub-pixel, the first two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 3 and 1 corresponding to R / 0.25 in Table 3), and the last two rows of sub-pixels illuminate the fourth and second sub-pixels (i.e., 4 and 2 corresponding to R / 0.25 in Table 3).

[0199] Correspondingly, in the third frame, for blue sub-pixels, the first two rows of sub-pixels illuminate the third and first sub-pixels (i.e., 3 1 corresponding to B / 0.25 in the third frame of Table 3), and the last two rows of sub-pixels illuminate the fourth and second sub-pixels (i.e., 4 2 corresponding to B / 0.25 in the third frame of Table 3); in the fourth frame, for blue sub-pixels, the first two rows of sub-pixels illuminate the first and third sub-pixels (i.e., 1 3 corresponding to B / 0.25 in the fourth frame of Table 3), and the last two rows of sub-pixels illuminate the second and fourth sub-pixels (i.e., 2 4 corresponding to B / 0.25 in the fourth frame of Table 3).

[0200] It should be understood that the distribution positions of multiple sub-pixels that are lit up in the same frame are different.

[0201] It should be noted that Tables 2 and 3 above are two examples provided in the embodiments of this application, and the embodiments of this application do not limit them.

[0202] In some embodiments, the mapping relationship of the first sub-pixel of the first frame is the same as the mapping relationship of the third sub-pixel of the second frame, and the mapping relationship of the third sub-pixel of the first frame is the same as the mapping relationship of the first sub-pixel of the second frame.

[0203] For example, Table 2 above shows that the position (1 3 2 4) of the lit sub-pixel in the red sub-pixel of the first frame is the same as the position (1 3 2 4) of the lit sub-pixel in the blue sub-pixel of the second frame, and the position (3 1 2 4) of the lit sub-pixel in the blue sub-pixel of the first frame is the same as the position (3 1 2 4) of the lit sub-pixel in the red sub-pixel of the second frame.

[0204] In some other embodiments, the mapping relationship of the first sub-pixel of the third frame is the same as the mapping relationship of the third sub-pixel of the fourth frame, and the mapping relationship of the third sub-pixel of the third frame is the same as the mapping relationship of the first sub-pixel of the fourth frame.

[0205] For example, Table 2 above shows that the position (4 2 1 3) of the lit sub-pixel in the red sub-pixel of the third frame is the same as the position (4 2 1 3) of the lit sub-pixel in the blue sub-pixel of the fourth frame, and the position (2 4 1 3) of the lit sub-pixel in the blue sub-pixel of the third frame is the same as the position (2 4 1 3) of the lit sub-pixel in the red sub-pixel of the fourth frame. Therefore, the mapping relationship of the first sub-pixel and the mapping relationship of the third sub-pixel can be used interchangeably.

[0206] The above provides a detailed overview of the positions of the sub-pixels illuminated by the first sub-mapping relationship.

[0207] The following explains the positions of the sub-pixels that are lit up by the second sub-pixel relationship.

[0208] In some embodiments, in the second sub-mapping relationship, any two rows of sub-pixels light up the same seed pixels in the odd-numbered cycle unit, and the other two rows of sub-pixels light up the same seed pixels in the even-numbered cycle unit.

[0209] For example, taking the first frame as an example, the first row of sub-pixels illuminates the same seed pixels in the odd-numbered cycle unit, the second row of sub-pixels illuminates the same seed pixels in the even-numbered cycle unit, the third row of sub-pixels illuminates the same seed pixels in the even-numbered cycle unit, and the fourth row of sub-pixels illuminates the same seed pixels in the odd-numbered cycle unit.

[0210] As shown in Figure 16, the second sub-mapping relationship corresponds to the L0.5 grayscale image. This sub-mapping relationship includes, but is not limited to, loop unit c, loop unit d, loop unit e, and loop unit f. Loop unit c can be the first loop unit, loop unit d can be the second loop unit, loop unit e can be the third loop unit, and loop unit f can be the fourth loop unit.

[0211] Referring to Figure 16, taking the fourth frame as an example, the first row of sub-pixels and the second row of sub-pixels illuminate the same seed pixels in loop unit c (first loop unit) and loop unit e (third loop unit), and the third row of sub-pixels and the fourth row of sub-pixels illuminate the same seed pixels in loop unit d (second loop unit) and loop unit f (fourth loop unit).

[0212] It should be understood that each row of sub-pixels in this sub-mapping relationship includes four red sub-pixels, four green sub-pixels, and four blue sub-pixels. Since the second sub-mapping relationship corresponds to the L0.5 grayscale image, each row of red, green, and blue sub-pixels will light up two corresponding sub-pixels.

[0213] Specifically, the position of each lit sub-pixel in different frames can be seen in Table 4 below.

[0214] Table 4

[0215] In the table, R represents red subpixels, G represents green subpixels, and B represents blue subpixels; 0.5 represents L0.5 grayscale image.

[0216] The following explanation of Table 4 will use the first frame as an example:

[0217] For the red sub-pixels in the first frame, the red sub-pixels in the first row light up the red sub-pixels in the odd-numbered cycle unit (i.e., corresponding to "1 / 3" in R / 0.5 of the first frame in Table 4), the red sub-pixels in the second row light up the red sub-pixels in the even-numbered cycle unit (i.e., corresponding to "2 / 4" in R / 0.5 of the first frame in Table 4), the red sub-pixels in the third row light up the red sub-pixels in the even-numbered cycle unit (i.e., corresponding to "2 / 4" in R / 0.5 of the first frame in Table 4), and the red sub-pixels in the fourth row light up the red sub-pixels in the odd-numbered cycle unit (i.e., corresponding to "1 / 3" in R / 0.5 of the first frame in Table 4).

[0218] At the same time, it can be determined that the number of positive red sub-pixels and the number of negative red sub-pixels in the illuminated red sub-pixels are equal. For example, in the first frame, the number of positive red sub-pixels and the number of negative red sub-pixels in the illuminated red sub-pixels are both 4.

[0219] For the green sub-pixels in the first frame, the green sub-pixels in the first row light up the green sub-pixels in the odd-numbered cycle unit (i.e., corresponding to "1 / 3" in G / 0.5 of the first frame in Table 4), the green sub-pixels in the second row light up the green sub-pixels in the even-numbered cycle unit (i.e., corresponding to "2 / 4" in G / 0.5 of the first frame in Table 4), the green sub-pixels in the third row light up the green sub-pixels in the even-numbered cycle unit (i.e., corresponding to "2 / 4" in G / 0.5 of the first frame in Table 4), and the green sub-pixels in the fourth row light up the green sub-pixels in the odd-numbered cycle unit (i.e., corresponding to "1 / 3" in G / 0.5 of the first frame in Table 4).

[0220] At the same time, it can be determined that the number of positive green sub-pixels and the number of negative green sub-pixels in the illuminated green sub-pixels are equal. For example, in the first frame, the number of positive green sub-pixels and the number of negative green sub-pixels in the illuminated green sub-pixels are both 4.

[0221] For the blue sub-pixels in the first frame, the blue sub-pixels in the first row light up the blue sub-pixels in the odd-numbered cycle unit (i.e., corresponding to "1 / 3" in B / 0.5 of the first frame in Table 4), the blue sub-pixels in the second row light up the blue sub-pixels in the even-numbered cycle unit (i.e., corresponding to "2 / 4" in B / 0.5 of the first frame in Table 4), the blue sub-pixels in the third row light up the blue sub-pixels in the even-numbered cycle unit (i.e., corresponding to "2 / 4" in B / 0.5 of the first frame in Table 4), and the blue sub-pixels in the fourth row light up the blue sub-pixels in the odd-numbered cycle unit (i.e., corresponding to "1 / 3" in B / 0.5 of the first frame in Table 4).

[0222] At the same time, it can be determined that the number of positive blue sub-pixels and the number of negative blue sub-pixels in the illuminated blue sub-pixels are equal. For example, in the first frame, the number of positive blue sub-pixels and the number of negative blue sub-pixels in the illuminated blue sub-pixels are both 4.

[0223] The above provides a detailed overview of the positions of the sub-pixels illuminated by the second sub-mapping relationship.

[0224] The following explains the positions of the sub-pixels illuminated by the third sub-mapping relationship.

[0225] In some embodiments, in the third sub-mapping relationship, the position of the lit sub-pixel is complementary to the position of the lit sub-pixel in the first sub-mapping relationship.

[0226] For example, referring to Figure 14, as shown in Figure 17, each frame in this sub-mapping relationship (first frame, second frame, third frame, and fourth frame) includes four rows of sub-pixels, and each row of sub-pixels includes four red sub-pixels, four green sub-pixels, and four blue sub-pixels. Since the third sub-mapping relationship corresponds to the L0.75 grayscale image, the red, green, and blue sub-pixels in each row each light up three corresponding sub-pixels.

[0227] It should be understood that in the third sub-mapping relationship, the positions of the unlit sub-pixels are the same as the positions of the lit sub-pixels in the first sub-mapping relationship. In other words, the positions of the lit sub-pixels are complementary to the positions of the lit sub-pixels in the first sub-mapping relationship.

[0228] Specifically, the position of each lit sub-pixel in different frames can be seen in Table 5 below.

[0229] Table 5

[0230] In the table, R represents red subpixels, G represents green subpixels, and B represents blue subpixels; 0.75 represents L0.75 grayscale image.

[0231] Simultaneously, it can be determined that in the third sub-mapping relationship, the number of positive polarity subpixels and the number of negative polarity subpixels in the corresponding illuminated subpixels are equal. For example, in the first frame, the number of positive polarity red subpixels and the number of negative polarity red subpixels in the illuminated red subpixels are both 6; the number of positive polarity green subpixels and the number of negative polarity green subpixels in the illuminated green subpixels are both 6; and the number of positive polarity blue subpixels and the number of negative polarity blue subpixels in the illuminated blue subpixels are both 6.

[0232] Table 5 above shows the positions of the lit sub-pixels in the L0.75 grayscale image, which in turn determines the positions of the unlit sub-pixels.

[0233] In some embodiments, in the first frame and the second frame, for the first sub-pixel and the third sub-pixel, the unlit sub-pixel is located in the odd-numbered positions of the first two rows of sub-pixels and the even-numbered positions of the last two rows of sub-pixels; for the second sub-pixel, the unlit sub-pixel is located in the even-numbered positions of the first two rows of sub-pixels and the odd-numbered positions of the last two rows of sub-pixels.

[0234] For example, as shown in Table 5 above, in the first frame, for red sub-pixels, the unlit sub-pixels are located in the first and third positions of the first two rows of sub-pixels, and the unlit sub-pixels are located in the second and fourth positions of the last two rows of sub-pixels. Correspondingly, in the first frame, for red sub-pixels, the lit sub-pixels in the first row are located in the second, third, and fourth positions (i.e., 2, 3, and 4 corresponding to R / 0.75 in the first frame in Table 5), and the lit sub-pixels in the second row are located in the first, second, and fourth positions (i.e., 1, 2, and 4 corresponding to R / 0.75 in the first frame in Table 5). These are the positions of the lit sub-pixels in the first two rows of red sub-pixels in the first frame.

[0235] The positions of the lit sub-pixels in the third row are the first, third, and fourth positions (i.e., 1, 3, and 4 corresponding to R / 0.75 in the first frame of Table 5). The positions of the lit sub-pixels in the fourth row are the first, second, and third positions (i.e., 1, 2, and 3 corresponding to R / 0.75 in the first frame of Table 5). This refers to the positions of the last two rows of lit sub-pixels of the red sub-pixels in the first frame.

[0236] In the second frame, for red sub-pixels, the unlit sub-pixels are located in the third and first positions of the first two rows of sub-pixels, and the unlit sub-pixels are located in the fourth and second positions of the last two rows of sub-pixels. Correspondingly, in the second frame, for red sub-pixels, the lit sub-pixels in the first row are located in the first, second, and fourth positions (i.e., 1, 2, 4 corresponding to R / 0.75 in Table 5), and the lit sub-pixels in the second row are located in the second, third, and fourth positions (i.e., 2, 3, 4 corresponding to R / 0.75 in Table 5). This refers to the positions of the lit sub-pixels in the first two rows of red sub-pixels in the second frame.

[0237] The positions of the lit sub-pixels in the third row are the first, second, and third positions (i.e., 1, 2, and 3 corresponding to R / 0.75 in the second frame of Table 5). The positions of the lit sub-pixels in the fourth row are the first, third, and fourth positions (i.e., 1, 3, and 4 corresponding to R / 0.75 in the second frame of Table 5). This refers to the positions of the last two rows of lit sub-pixels of the red sub-pixels in the second frame.

[0238] In another example, in the first frame, for blue sub-pixels, unlit sub-pixels are in the third and first positions of the first two rows of sub-pixels, and unlit sub-pixels are in the fourth and second positions of the last two rows of sub-pixels.

[0239] Accordingly, in the first frame, for the blue sub-pixels, the positions of the lit sub-pixels in the first row are the first, second, and fourth positions (i.e., 1, 2, and 4 corresponding to B / 0.75 in the first frame of Table 5), and the positions of the lit sub-pixels in the second row are the second, third, and fourth positions (i.e., 2, 3, and 4 corresponding to B / 0.75 in the first frame of Table 5). This is the position of the first two rows of lit sub-pixels of the blue sub-pixels in the first frame.

[0240] The positions of the lit sub-pixels in the third row are the first, second, and third positions (i.e., 1, 2, and 3 corresponding to B / 0.75 in the first frame of Table 5). The positions of the lit sub-pixels in the fourth row are the first, third, and fourth positions (i.e., 1, 3, and 4 corresponding to B / 0.75 in the first frame of Table 5). This refers to the positions of the last two rows of lit sub-pixels of the blue sub-pixels in the first frame.

[0241] In the second frame, for blue sub-pixels, the unlit sub-pixels are located in the first and third positions of the first two rows of sub-pixels, and the unlit sub-pixels are located in the second and fourth positions of the last two rows of sub-pixels. Correspondingly, in the second frame, for blue sub-pixels, the lit sub-pixels in the first row are located in the second, third, and fourth positions (i.e., 2, 3, and 4 corresponding to B / 0.75 in Table 5), and the lit sub-pixels in the second row are located in the first, second, and fourth positions (i.e., 1, 2, and 4 corresponding to B / 0.75 in Table 5). This refers to the positions of the lit sub-pixels in the first two rows of blue sub-pixels in the second frame.

[0242] The positions of the lit sub-pixels in the third row are the first, third, and fourth positions (i.e., 1, 3, and 4 corresponding to B / 0.75 in the second frame of Table 5). The positions of the lit sub-pixels in the fourth row are the first, second, and third positions (i.e., 1, 2, and 3 corresponding to B / 0.75 in the second frame of Table 5). This refers to the positions of the last two rows of lit sub-pixels of the blue sub-pixels in the second frame.

[0243] In some other embodiments, in the third and fourth frames, for the first and third sub-pixels, the unlit sub-pixels are located in the even positions of the first two rows of sub-pixels and the odd positions of the last two rows of sub-pixels; for the second sub-pixel, the unlit sub-pixels are located in the odd positions of the first two rows of sub-pixels and the even positions of the last two rows of sub-pixels.

[0244] For example, as shown in Table 5 above, in the third frame, for red sub-pixels, the unlit sub-pixels are located in the fourth and second positions of the first two rows of sub-pixels, and the unlit sub-pixels are located in the third and first positions of the last two rows of sub-pixels. Correspondingly, in the third frame, for red sub-pixels, the lit sub-pixels in the first row are located in the first, second, and third positions (i.e., 1, 2, 3 corresponding to R / 0.75 in Table 5), and the lit sub-pixels in the second row are located in the first, third, and fourth positions (i.e., 1, 3, 4 corresponding to R / 0.75 in Table 5). These are the positions of the lit sub-pixels in the first two rows of red sub-pixels in the third frame.

[0245] The positions of the lit sub-pixels in the third row are the first, second, and fourth positions (i.e., 1, 2, and 4 corresponding to R / 0.75 in the third frame of Table 5). The positions of the lit sub-pixels in the fourth row are the second, third, and fourth positions (i.e., 2, 3, and 4 corresponding to R / 0.75 in the third frame of Table 5). This refers to the positions of the last two rows of lit sub-pixels of the red sub-pixels in the third frame.

[0246] In the fourth frame, for red sub-pixels, the unlit sub-pixels are located in the second and fourth positions of the first two rows of sub-pixels, and the unlit sub-pixels are located in the first and third positions of the last two rows of sub-pixels. Correspondingly, in the fourth frame, for red sub-pixels, the lit sub-pixels in the first row are located in the first, third, and fourth positions (i.e., 1, 3, and 4 corresponding to R / 0.75 in the fourth frame of Table 5), and the lit sub-pixels in the second row are located in the first, second, and third positions (i.e., 1, 2, and 3 corresponding to R / 0.75 in the fourth frame of Table 5). This refers to the positions of the lit sub-pixels in the first two rows of red sub-pixels in the fourth frame.

[0247] The positions of the lit sub-pixels in the third row are the second, third, and fourth positions (i.e., 2, 3, and 4 corresponding to R / 0.75 in the fourth frame of Table 5). The positions of the lit sub-pixels in the fourth row are the first, second, and fourth positions (i.e., 1, 2, and 4 corresponding to R / 0.75 in the fourth frame of Table 5). This refers to the positions of the last two rows of lit sub-pixels of the red sub-pixels in the fourth frame.

[0248] In another example, in the third frame, for blue sub-pixels, the unlit sub-pixels are located in the second and fourth positions of the first two rows of sub-pixels, and the unlit sub-pixels are located in the first and third positions of the last two rows of sub-pixels. Correspondingly, in the third frame, for blue sub-pixels, the lit sub-pixels in the first row are located in the first, third, and fourth positions (i.e., 1, 3, and 4 corresponding to B / 0.75 in the third frame of Table 5), and the lit sub-pixels in the second row are located in the first, second, and third positions (i.e., 1, 2, and 3 corresponding to B / 0.75 in the third frame of Table 5). Here, these are the positions of the lit sub-pixels in the first two rows of blue sub-pixels in the third frame.

[0249] The positions of the lit sub-pixels in the third row are the second, third, and fourth positions (i.e., 2, 3, and 4 corresponding to B / 0.75 in the third frame of Table 5). The positions of the lit sub-pixels in the fourth row are the first, second, and fourth positions (i.e., 1, 2, and 4 corresponding to B / 0.75 in the third frame of Table 5). This refers to the positions of the last two rows of lit sub-pixels of the blue sub-pixels in the third frame.

[0250] In the fourth frame, for blue sub-pixels, the unlit sub-pixels are located in the fourth and second positions of the first two rows of sub-pixels, and the unlit sub-pixels are located in the third and first positions of the last two rows of sub-pixels. Correspondingly, in the fourth frame, for blue sub-pixels, the lit sub-pixels in the first row are located in the first, second, and third positions (i.e., 1, 2, 3 corresponding to B / 0.75 in the fourth frame of Table 5), and the lit sub-pixels in the second row are located in the first, third, and fourth positions (i.e., 1, 3, 4 corresponding to B / 0.75 in the fourth frame of Table 5). This refers to the positions of the lit sub-pixels in the first two rows of blue sub-pixels in the fourth frame.

[0251] The positions of the lit sub-pixels in the third row are the first, second, and fourth positions (i.e., 1, 2, 4 corresponding to B / 0.75 in the fourth frame of Table 5). The positions of the lit sub-pixels in the fourth row are the second, third, and fourth positions (i.e., 2, 3, 4 corresponding to B / 0.75 in the fourth frame of Table 5). This refers to the positions of the last two rows of lit sub-pixels of the blue sub-pixels in the fourth frame.

[0252] Specifically, the position of each lit sub-pixel in different frame images can also be seen in Table 6 below.

[0253] Table 6

[0254] In the table, R represents red subpixels, G represents green subpixels, and B represents blue subpixels; 0.75 represents L0.75 grayscale image.

[0255] As can be seen from Table 6 above, in the first frame and the second frame, for the first sub-pixel and the third sub-pixel, the unlit sub-pixels are located in the even positions of the first two rows of sub-pixels and the odd positions of the last two rows of sub-pixels; for the second sub-pixel, the unlit sub-pixels are located in the odd positions of the first two rows of sub-pixels and the even positions of the last two rows of sub-pixels.

[0256] In the third and fourth frames, for the first and third sub-pixels, the unlit sub-pixels are located in the odd-numbered positions of the first two rows of sub-pixels and the even-numbered positions of the last two rows of sub-pixels; for the second sub-pixel, the unlit sub-pixels are located in the even-numbered positions of the first two rows of sub-pixels and the odd-numbered positions of the last two rows of sub-pixels.

[0257] It should be understood that multiple unlit sub-pixels in the same frame are located in different positions.

[0258] It should be noted that Tables 5 and 6 above are two examples provided in the embodiments of this application, and the embodiments of this application do not limit them.

[0259] In some embodiments, the mapping relationship of the first sub-pixel of the first frame is the same as the mapping relationship of the third sub-pixel of the second frame, and the mapping relationship of the third sub-pixel of the first frame is the same as the mapping relationship of the first sub-pixel of the second frame.

[0260] For example, Table 5 above shows that the position of the lit sub-pixel in the red sub-pixel of the first frame (2 3 4 / 1 2 4 / 1 3 4 / 1 2 3) is the same as the position of the lit sub-pixel in the blue sub-pixel of the second frame (2 3 4 / 1 2 4 / 1 3 4 / 1 2 3), and the position of the lit sub-pixel in the blue sub-pixel of the first frame (1 2 4 / 2 3 4 / 1 2 3 / 1 3 4) is the same as the position of the lit sub-pixel in the red sub-pixel of the second frame (1 2 4 / 2 3 4 / 1 2 3 / 1 3 4).

[0261] In some other embodiments, the mapping relationship of the first sub-pixel of the third frame is the same as the mapping relationship of the third sub-pixel of the fourth frame, and the mapping relationship of the third sub-pixel of the third frame is the same as the mapping relationship of the first sub-pixel of the fourth frame.

[0262] For example, Table 5 above shows that the positions of the lit sub-pixels in the red sub-pixels of the third frame (1 2 3 / 1 3 4 / 1 2 4 / 2 3 4) are the same as the positions of the lit sub-pixels in the blue sub-pixels of the fourth frame (1 2 3 / 1 3 4 / 1 2 4 / 2 3 4), and the positions of the lit sub-pixels in the blue sub-pixels of the third frame (1 3 4 / 1 2 3 / 2 3 4 / 1 2 4) are the same as the positions of the lit sub-pixels in the red sub-pixels of the fourth frame (1 3 4 / 1 2 3 / 2 3 4 / 1 2 4). Therefore, the mapping relationships of the first and third sub-pixels can be used interchangeably.

[0263] The above provides a detailed explanation of the patterns of the lit sub-pixels in the first, second, and third sub-mapping relationships.

[0264] In some embodiments, the illuminated sub-pixels of at least two of the multiple frame frames are distributed in different positions; within the same sub-mapping relationship, the multiple frame frames are randomly arranged and combined.

[0265] For example, referring to Figures 14 to 17, in the first sub-mapping relationship, the mapping relationship between the first frame and the fourth frame can be randomly arranged and combined, for example, the order can be adjusted to: third frame, second frame, first frame, fourth frame, and then displayed in a loop after arrangement. It should be understood that the above arrangement is only for the purpose of understanding this solution, and the embodiments of this application do not limit it.

[0266] Similarly, the mapping relationships between frames in the second and third sub-mapping relationships can also be randomly permuted and combined. It should be noted that random permutations and combinations of frames can occur within the same sub-mapping relationship.

[0267] In some embodiments, the illuminated sub-pixels of at least two of the multiple frame frames are distributed in different positions; within the same sub-pixel, the multiple frame frames are randomly arranged and combined.

[0268] For example, referring to Figures 11 to 13, in terms of sub-pixels, there are four frames in each sub-pixel (red sub-pixel, green sub-pixel, blue sub-pixel) at different gray levels (L0.25 gray level, L0.5 gray level, L0.75 gray level), and different mapping relationships are displayed. These four frames can be arbitrarily arranged and combined, and displayed cyclically, so each frame can have 4*3*2*1=24 displayable mapping relationships.

[0269] It should be noted that the above permutations and combinations of mapping relationships do not include cases where the same frame appears twice or more in four frames.

[0270] In some embodiments, within the same loop unit, when the polarity of the first sub-pixel is opposite to that of the third sub-pixel, the mapping relationship of the first sub-pixel and the mapping relationship of the third sub-pixel are interchanged.

[0271] For example, as shown in Figure 18, since an L1 grayscale image can display the polarity of all sub-pixels, an L1 grayscale image is used as an example. Assume the first sub-pixel is a red sub-pixel, the second sub-pixel is a green sub-pixel, and the third sub-pixel is a blue sub-pixel.

[0272] Referring to Figure 18, in the first loop unit, the polarity of the red sub-pixels in the first row is positive, and the polarity of the blue sub-pixels in the first row is negative; in the third loop unit, the polarity of the red sub-pixels in the first row is negative, and the polarity of the blue sub-pixels in the first row is positive.

[0273] In other words, within a loop unit, the polarity of the red sub-pixel is opposite to that of the blue sub-pixel. Furthermore, combining Figure 11 (mapping relationship of red sub-pixels) and Figure 13 (mapping relationship of blue sub-pixels), the mapping relationships between the two sub-pixels can be interchanged. Moreover, after interchange, the number of positive polarity sub-pixels and the number of negative polarity sub-pixels of the corresponding illuminated sub-pixels remain equal.

[0274] It should be understood that the above mapping relationship applies to the dual-gate driving architecture. Since the polarities of red and blue subpixels in the same cyclic unit are always opposite, and the number of red subpixels displaying "positive polarity" and the number of red subpixels displaying "negative polarity" are the same, then the number of blue subpixels must also be the same. Therefore, the corresponding mapping relationship between red and blue subpixels can be used interchangeably. However, green subpixels do not follow this rule (they are completely independent), so the mapping relationship of green subpixels cannot be used interchangeably with that of red and blue subpixels.

[0275] The methods described in the following embodiments can all be implemented in a display device 800 having the above-described hardware structure. The methods of the embodiments of this application will be described below.

[0276] The pixel processing method provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0277] This application embodiment enables the multiple illuminated pixels of each sub-pixel to maintain polarity balance in each frame, thereby avoiding flickering issues between different sub-pixels. The following, in conjunction with the accompanying drawings, details a pixel processing method provided by this application embodiment. This method is applied to a display device, which includes a display panel for displaying multiple different grayscale images.

[0278] It should be understood that the display device also includes a memory and a processor. The memory is used to store pre-defined mapping relationships, and the processor can read the pre-defined mapping relationships from the memory.

[0279] Furthermore, this pixel processing method can be applied to the processor in a display device.

[0280] As shown in Figure 19, the pixel processing method may include steps 1901-1902. Step 1901 can also be referred to as the "determining target mapping relationship" process, and step 1902 can also be referred to as the "illuminating multiple sub-pixels of the second grayscale image" process. Steps 1901-1902 are described in detail below.

[0281] Step 1901: Determine the target mapping relationship that matches the grayscale value of the second grayscale image according to the preset mapping relationship.

[0282] The second grayscale image includes, but is not limited to, a 0.25 grayscale image, a 0.5 grayscale image, and a 0.75 grayscale image.

[0283] For example, when a display device displays any one of the grayscale images in the second grayscale image, the processor can retrieve the aforementioned 0.25 grayscale image, 0.5 grayscale image, and 0.75 grayscale image from the memory, and obtain a target mapping relationship that is the same as the grayscale value of the displayed second grayscale image from the mapping relationship corresponding to the three different grayscale images.

[0284] In another example, the processor directly retrieves from memory the target mapping relationship that is the same as the grayscale value of the second grayscale image being displayed.

[0285] Step 1902: Based on the target mapping relationship, illuminate multiple sub-pixels of the second grayscale image.

[0286] In the second grayscale image, the number of positive sub-pixels is equal to the number of negative sub-pixels among multiple sub-pixels.

[0287] For example, taking a target mapping relationship of L0.25 grayscale image as an example, the processor illuminates the sub-pixels in the grayscale image according to the mapping relationship corresponding to the obtained L0.25 grayscale image, thereby ensuring the balance between positive and negative sub-pixels and avoiding screen flickering, which affects the user's viewing experience.

[0288] As shown in Figure 20, this application embodiment provides a pixel processing device, which includes a processing unit 2001 and an acquisition unit 2002.
