[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Please see Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the driving method for a display panel in this application. This application discloses a driving method for a display panel, wherein the display panel includes a plurality of display sub-pixels, and the driving method includes:

[0039] S1: Obtain the image to be displayed, which contains the first display data of multiple image sub-pixels.

[0040] First, the image to be displayed is obtained. Since the image to be displayed contains the first display data of multiple image sub-pixels, the first display data of the image sub-pixels is then processed to obtain the data required for the display panel to display the image to be displayed.

[0041] S2: Map the first display data of multiple image sub-pixels to second display data for driving each display sub-pixel of the display panel to emit light, and at least some of the first display data of the image sub-pixels are mapped to second display data for driving at least two display sub-pixels with the same emission color to emit light.

[0042] By mapping first display data of multiple image subpixels to second display data for driving the light emission of each display subpixel of the display panel, and by mapping at least some of the first display data of the image subpixels to second display data for driving at least two display subpixels with the same emission color to emit light, the one-to-one correspondence between the first display data and the second display data of the image subpixels in the prior art can be changed, thereby reducing the amount of data in the first display data of the image subpixels and the size of the memory occupied.

[0043] S3: Display the data on the display panel based on the second display data.

[0044] After mapping the first display data of multiple image sub-pixels to the second display data used to drive the light emission of each display sub-pixel of the display panel, the display panel is made to display based on the second display data, thus completing the display driving of the display panel in this application.

[0045] In this application, by mapping the first display data of at least some image sub-pixels to the second display data used to drive at least two display sub-pixels with the same emission color to emit light, the amount of data in the first display data can be reduced, thereby reducing power consumption and memory occupied by the first display data.

[0046] Please see Figure 2 , Figure 2 This is a schematic diagram illustrating an embodiment of the correspondence between image subpixels and display subpixels in this application. The image to be displayed includes multiple image pixel units, and each image pixel unit includes multiple image subpixels. The display panel includes multiple display units, and each display unit includes multiple display subpixels. At least two display subpixels in each display unit have the same emission color. One image pixel unit corresponds to one display unit, and the color of one image subpixel is the same as the emission color of at least one display subpixel in the corresponding display unit. By designing one image pixel unit to one display unit, and one image subpixel having the same emission color as at least one display subpixel in the corresponding display unit, mapping of image subpixels with the same emission color to display subpixels can be achieved. Image subpixels with different emission colors cannot be mapped to display subpixels.

[0047] Please see Figure 3 , Figure 3 For this application Figure 1 A flowchart illustrating an embodiment of step S2; step S2, which maps first display data of multiple image sub-pixels to second display data for driving the light emission of each display sub-pixel of the display panel, includes:

[0048] S21: Determine the display unit corresponding to each image pixel unit;

[0049] By mapping one image pixel unit to one display unit, preparations are made for mapping the first display data of the image sub-pixel to the second display data used to drive the display sub-pixel to emit light.

[0050] S22: Map the first display data of each image sub-pixel in each image pixel unit to the second display data used to drive the display sub-pixel with the corresponding luminous color in the corresponding display unit to emit light.

[0051] By mapping image sub-pixels with the same emission color in an image pixel unit to display sub-pixels in a display unit, the first display data of each image sub-pixel in each image pixel unit is mapped to the second display data used to drive the display sub-pixels with the corresponding emission color in the corresponding display unit to emit light.

[0052] Please continue reading. Figure 2 Each image pixel unit includes a first image sub-pixel R1, a second image sub-pixel G1, and a third image sub-pixel B1. Each display unit includes at least one first display sub-pixel R2, at least two second display sub-pixels G2, and at least one third display sub-pixel B2. The first display data of the first image sub-pixel R1 is mapped to second display data for driving at least one first display sub-pixel R2 to emit light; the first display data of the second image sub-pixel G1 is mapped to second display data for driving at least two second display sub-pixels G2 to emit light; and the first display data of the third image sub-pixel B1 is mapped to second display data for driving at least one third display sub-pixel B2 to emit light. Therefore, when the image pixel unit is arranged in an R1G1B1 pixel arrangement, and the display unit is arranged in an R2G2B2G2 pixel arrangement, only one set of image pixel units is needed to complete the pixel mapping of the display unit. In the prior art, since image sub-pixels of the same color need to correspond to display sub-pixels, when the display unit is arranged in R2G2B2G2 pixel arrangement, at least two sets of image pixel units arranged in R1G1B1 pixel arrangement are needed to map the display unit. Therefore, this embodiment can save the memory space occupied by storing image sub-pixels.

[0053] Please continue reading. Figure 2 The display subpixel portion of the display unit contains a first display subpixel R2, two second display subpixels G2, and a third display subpixel B2; that is, the display unit is arranged as R2G2B2G2 pixels.

[0054] Preferably, multiple display sub-pixels within the same display unit are arranged at intervals along a first direction X, and a first display sub-pixel R2 or a third display sub-pixel B2 is spaced apart between two second display sub-pixels G2. Image sub-pixels within the same image pixel unit are also arranged at intervals along the first direction X. When the arrangement direction of the image sub-pixels in the same image pixel unit is the same as the arrangement direction of the multiple display sub-pixels within its corresponding same display unit, it is beneficial to map the first display data to the second display data.

[0055] Please see Figure 4 , Figure 4This is a schematic diagram of another embodiment of the correspondence between image subpixels and display subpixels in this application. In one embodiment, each display unit includes two first display subpixels R2, four second display subpixels G2, and two third display subpixels B2. During the mapping process, the first display data of the first image subpixel R1 is mapped to the second display data used to drive the two first display subpixels R2 to emit light; the first display data of the second image subpixel G1 is mapped to the second display data used to drive the four second display subpixels G2 to emit light; and the first display data of the third image subpixel B1 is mapped to the second display data used to drive the two third display subpixels B2 to emit light. Therefore, when the image pixel unit is arranged in an R1G1B1 pixel arrangement and the display unit is arranged in an R2G2B2G2 pixel arrangement, only one set of R1G1B1 image pixel units is needed to complete the pixel mapping of the two sets of R2G2B2G2 pixel arrangements in the display unit.

[0056] In one embodiment, each display unit includes two first display sub-pixels R2, two second display sub-pixels G2, and two third display sub-pixels B2; that is, the display unit is arranged in two sets of R2G2B2 pixels. During the mapping process, the first display data of the first image sub-pixel R1 is mapped to the second display data used to drive the two first display sub-pixels R2 to emit light, the first display data of the second image sub-pixel G1 is mapped to the second display data used to drive the two second display sub-pixels G2 to emit light, and the first display data of the third image sub-pixel B1 is mapped to the second display data used to drive the two third display sub-pixels B2 to emit light. Therefore, when the image pixel unit is arranged in R1G1B1 pixels and the display unit is arranged in R2G2B2 pixels, only one set of R1G1B1 image pixel units is needed to complete the pixel mapping of the two sets of R2G2B2 pixel arrangements in the display unit.

[0057] Preferably, multiple display sub-pixels within the same display unit are arranged at intervals along a first direction X. In one embodiment, two sets of R2G2B2 pixel combinations are arranged at intervals along the first direction X; in another embodiment, two sets of R2G2B2 pixel combinations are arranged at intervals along a second direction Y. The image sub-pixels within the same image pixel unit are also arranged at intervals along the first direction X. When the arrangement direction of the image sub-pixels within the same image pixel unit is the same as the arrangement direction of the multiple display sub-pixels within its corresponding same display unit, it is beneficial to map the first display data to the second display data.

[0058] Please see Figure 5 , Figure 5This is a schematic diagram illustrating another embodiment of the correspondence between image subpixels and display subpixels in this application; each display unit includes four first display subpixels R2, four second display subpixels G2, and four third display subpixels B2. During the mapping process, the first display data of the first image subpixel R1 is mapped to second display data used to drive the four first display subpixels R2 to emit light; the first display data of the second image subpixel G1 is mapped to second display data used to drive the four second display subpixels G2 to emit light; and the first display data of the third image subpixel B1 is mapped to second display data used to drive the four third display subpixels B2 to emit light. Therefore, when the image pixel unit is arranged in an R1G1B1 pixel arrangement, and the display unit is arranged in an R2G2B2 pixel arrangement, only one set of R1G1B1 image pixel units is needed to complete the pixel mapping of the four sets of R2G2B2 pixel arrangements in the display unit.

[0059] Please see Figure 6 , Figure 6 This is a schematic diagram illustrating the determination of the rendering mode in this application; the driving processing unit 22 stores a first rendering mode and a second rendering mode, wherein, in the first rendering mode, the first display data of at least some image sub-pixels is mapped to second display data for driving at least 2N display sub-pixels with the same emission color to emit light, and in the second rendering mode, the first display data of one image sub-pixel is mapped to second display data for driving N display sub-pixels with the same emission color to emit light, where N is a positive integer; before the step of mapping the first display data of multiple image sub-pixels to second display data for driving the emission of each display sub-pixel of the display panel, the following steps are included:

[0060] S11: Determine if the current rendering mode is the first rendering mode;

[0061] When the image pixel unit is arranged in an R1G1B1 pixel arrangement and the display unit is arranged in an R2G2B2G2 pixel arrangement, only one set of R1G1B1 image pixel units is needed to complete the pixel mapping of the two sets of R2G2B2G2 pixel arrangements in the display unit. Each display unit contains two first display sub-pixels R2, four second display sub-pixels G2, and two third display sub-pixels B2; therefore, the first rendering mode is used for the second display sub-pixels G2, and the second rendering mode is used for the first display sub-pixels R2 and the third display sub-pixels B2.

[0062] S12: If so, proceed to the step of mapping the first display data of a plurality of image sub-pixels to second display data for driving each display sub-pixel of the display panel to emit light, and mapping the first display data of at least a portion of the image sub-pixels to second display data for driving 2N display sub-pixels with the same emission color to emit light.

[0063] When there is only one set of R2G2B2G2 pixels in the display unit, N can be 1, that is, the second image sub-pixel G1 is mapped to two second display sub-pixels G2 using the first rendering mode; when there are two sets of R2G2B2G2 pixels in the display unit, N can be 2, that is, the second image sub-pixel G1 is mapped to four second display sub-pixels G2 using the first rendering mode; and so on.

[0064] S13: Otherwise, enter the second rendering mode.

[0065] In the second rendering mode, the first display data of one image subpixel is mapped to the second display data of N display subpixels with the same emission color. When there is only one set of R2G2B2G2 pixels in the display unit, N can be 1, that is, the first image subpixel R1 and the third image subpixel B1 are mapped to one first display subpixel R2 and one third display subpixel B2 respectively using the second rendering mode; when there are two sets of R2G2B2G2 pixels in the display unit, N can be 2, that is, the first image subpixel R1 and the third image subpixel B1 are mapped to two first display subpixels R2 and two third display subpixels B2 respectively using the second rendering mode; and so on.

[0066] Please see Figure 7 , Figure 7 This is a schematic diagram of the driving device in this application. The driving device includes an acquisition module 1, a driving module 2, and a display module 3. The acquisition module 1 acquires an image to be displayed, which contains first display data of multiple image sub-pixels. The driving module 2 processes the acquired first display data using the driving method applied in the above embodiments, converting it into second display data and outputting it to the display module 3. The display module 3 displays the mapped second display data.

[0067] The driving module 2 includes a random access processor 21, a driving processing unit 22, and a color filter 23; wherein the random access processor 21 is used to receive first display data; the driving processing unit 22 maps the first display data to second display data; and the color filter 23 is used to achieve normal display. By setting the color filter 23, the jagged edges or color distortion problems of the display panel can be prevented, so that the display panel can achieve normal display.

[0068] Please see Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the composition of the drive processing unit in this application; Figure 9This is a flowchart illustrating an embodiment of the driving module processing first display data in this application; the driving processing unit 22 in the display panel performs the operation of mapping the first display data of multiple image sub-pixels to second display data for driving each display sub-pixel of the display panel to emit light. The driving processing unit 22 includes a shift register 24, a first data buffer 25, and a second data buffer 26; wherein, the step of the driving processing unit 22 mapping the first display data of multiple image sub-pixels to second display data for driving each display sub-pixel of the display panel to emit light includes:

[0069] S23: Store the first display data of multiple image sub-pixels in the image to be displayed in the random access memory, and transfer the first display data to the shift register.

[0070] The random access memory 21 is mainly used to obtain and store the first display data of multiple image sub-pixels in the image to be displayed from the acquisition module 1. The random access memory 21 is connected to the shift register 24 and transmits the first display data to the shift register 24.

[0071] S24: The shift register processes the obtained first display data to obtain the second display data.

[0072] In one embodiment, S24 further includes S241: mapping the first display data to at least two second display data.

[0073] By mapping the first display data to at least two second display data using shift register 24, less first display data is needed to achieve the same number of second display data settings, thereby reducing the memory required in the random access memory 21 that stores the first display data.

[0074] S25: The first data buffer performs a write operation on the second display data;

[0075] Please see Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of another embodiment of the correspondence between image sub-pixels and display sub-pixels in this application; Figure 11 This is a schematic diagram illustrating another embodiment of the correspondence between image subpixels and display subpixels in this application; in one embodiment, please refer to... Figure 4 and Figure 5 The first data buffer performs a row write operation on the second display data arranged along the first direction X; in another embodiment, please refer to Figure 10 and Figure 11 The first data buffer performs a column write operation on the second display data along the second direction Y.

[0076] S26: The second data buffer performs the corresponding storage operation on the second display data.

[0077] The first data register 25 and the second data register 26 repeatedly perform write and store operations until the mapping of all second display data is completed.

[0078] S27: The second data register transmits the second display data to the display panel for display via level converter 27, digital-to-analog converter 28 and amplifier 29.

[0079] Preferably, step S27 further includes: the second data register transmitting the same set of second display data to the display panel multiple times for display.

[0080] Each display unit comprises four first display sub-pixels R2, four second display sub-pixels G2, and four third display sub-pixels B2. The display unit is configured as follows: Figure 5 When the R2G2B2 pixel arrangement is shown, meaning that the display sub-pixels in the display units stacked in the second direction Y have the same color arrangement, the second data buffer 26 can perform the step of transferring the second display data to the display panel twice for display. In one embodiment, when each display unit includes a number of display sub-pixels greater than 4 and a multiple of 2, the second data buffer 26 can perform the step of transferring the second display data to the display panel multiple times for display, thereby mapping one image sub-pixel to multiple display sub-pixels of the same color.

[0081] In one embodiment, by extending the working time of the second data register, the second data register can transmit the same set of second display data to the display panel multiple times for display.

[0082] By extending the operating time of the second data register 26, the second data register 26 can transmit the same set of second display data to the display panel multiple times for display.

[0083] The second data register 26 transmits the second display data to the display panel for display via a level converter 27, a digital-to-analog converter 28, and an amplifier 29. When the first data register 25 and the digital-to-analog converter 28 communicate, the level converter 27 needs to resolve the level mapping problem between the two to achieve normal communication. The digital-to-analog converter 28 converts the received digital signal into an analog signal for output, and the amplifier 29 amplifies the received analog signal.

[0084] This application also includes a computer-readable storage medium storing computer program instructions, which, when executed by a processor, implement the display panel driving method described in the above embodiments. In one embodiment, the computer program instructions are stored in the integrated circuit (IC) of the display panel to facilitate the execution of the driving method described in the above embodiments.

[0085] Applying the driving method of this application, when the image pixel unit is arranged in an R1G1B1 pixel arrangement and the display unit is arranged in an R2G2B2G2 pixel arrangement, only one set of R1G1B1 image pixel units is needed to complete the pixel mapping of two sets of R2G2B2G2 pixel arrangements in the display unit. When the display unit is arranged in an R2G2B2 pixel arrangement, only one set of R1G1B1 image pixel units is needed to complete the pixel mapping of four sets of R2G2B2 pixel arrangements in the display unit. Simultaneously, the first data buffer 25 performs a row write operation on the second display data arranged along the first direction X; in another embodiment, the first data buffer 25 can also perform a column write operation on the second display data arranged along the second direction Y, with various implementation methods.

[0086] In this application, by mapping the first display data of at least some image sub-pixels to the second display data used to drive at least two display sub-pixels with the same emission color to emit light, the amount of data in the first display data can be reduced, thereby reducing power consumption and memory occupied by the first display data.
