Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a display device and its driving method. Background Technology

[0002] Existing display panels employ VAC (View Angle Compensation) technology to compensate for viewing angles. The key to VAC technology lies in using a combination of high-grayscale pixels (H) and low-grayscale pixels (L) to achieve intermediate grayscale display, thereby reducing the variation in gamma value when viewed from the side and improving the viewing angle characteristics of the display panel. However, using a combination of high-grayscale pixels (H) and low-grayscale pixels (L) results in higher power consumption when the display panel is operating with VAC enabled. Summary of the Invention

[0003] This application provides a display device and its driving method, which aims to reduce the power consumption of the display device when the VAC function is enabled.

[0004] On one hand, embodiments of this application provide a driving method for a display device, the display device including a display panel, the display panel including a plurality of pixels, the plurality of pixels being arranged in 2M pixel columns and 2N pixel rows, where M and N are both positive integers; the driving method includes the following steps: receiving at least one original frame; generating a first frame based on the original frame, wherein the grayscale value of the first grayscale data to be input to any pixel of the display panel in the first frame is greater than or less than the grayscale value of the original grayscale data to be input to the same pixel in the original frame; generating a second frame based on the first frame. The system consists of two frames and one third frame, wherein the second grayscale data of the second frame includes the grayscale data of the pixels in the odd pixel row of the first frame to be input to the display panel, and the third grayscale data of the third frame includes the grayscale data of the pixels in the odd pixel row of the first frame to be input to the display panel; and the system sequentially displays one frame of the second frame and one frame of the third frame within a first driving cycle and a second driving cycle, wherein the first driving cycle and the second driving cycle are two driving cycles that are consecutive in time, and the sum of the first driving cycle and the second driving cycle is equal to the driving cycle of one frame of the original frame.

[0005] On the other hand, embodiments of this application also provide a display device, the display device including a system chip and a display panel, the display panel including a plurality of pixels, the plurality of pixels being arranged in 2M pixel columns and 2N pixel rows, where M and N are both positive integers; wherein, the system chip is configured to receive at least one original frame, and to generate a first frame based on the original frame, and to generate a second frame and a third frame based on the first frame, wherein the grayscale value of the first grayscale data to be input to any pixel of the display panel in the first frame is greater than or less than the grayscale value to be input to the same pixel in the original frame. The original grayscale data includes grayscale values ​​of the original grayscale data. The second grayscale data of the second image includes grayscale data of pixels in the odd pixel row of the first image to be input to the display panel. The third grayscale data of the third image includes grayscale data of pixels in the odd pixel row of the first image to be input to the display panel. The display panel is used to sequentially display one frame of the second image and one frame of the third image in a first driving cycle and a second driving cycle, wherein the first driving cycle and the second driving cycle are two driving cycles that are consecutive in time, and the sum of the first driving cycle and the second driving cycle is equal to the driving cycle of one frame of the original image.

[0006] In the display device and driving method provided in this application, a first frame is generated from an original frame using viewing angle compensation (VAC) technology, and a second frame and a third frame are generated from the first frame after viewing angle compensation. The second grayscale data of the second frame includes the grayscale data of pixels in the odd-pixel rows of the first frame to be input to the display panel. The third grayscale data of the third frame includes the grayscale data of pixels in the odd-pixel rows of the first frame to be input to the display panel. During a first driving cycle when the display panel displays the second frame, pixels in multiple odd-pixel rows are sequentially activated row by row. During a second driving cycle when the display panel displays the third frame, pixels in multiple odd-pixel rows are sequentially activated row by row. Therefore, the display device provided in this application can, under the premise of compensating for the viewing angle (VAC function enabled), make the grayscale value of the grayscale data displayed in each second frame of the screen change less, and make the grayscale value of the grayscale data displayed in each third frame of the screen change less. That is, in the driving cycle of a frame of the screen (first driving cycle, second driving cycle), the grayscale data transmitted by a data line flips less, thereby avoiding frequent and large changes in the grayscale value of the grayscale data input to the odd pixel row and the odd pixel row when the display panel displays a frame of the screen (large grayscale data flip), thereby reducing the load of the display device and the power consumption when the VAC function is enabled.

[0047] The following example uses a solid color image (all grayscale values ​​are 128) as an illustration:

[0048] If, in the original image, the grayscale values ​​of all pixels to be input to the display panel are equal (each grayscale value is 128), then the grayscale value of the pixel in the second image located in the (2i-1)th pixel column and the (2j-1)th pixel row to be input to the display panel is greater than the grayscale value of the pixel in the third image located in the (2i-1)th pixel column and the (2j-1)th pixel row to be input to the display panel. Furthermore, the grayscale value of the pixel in the second image located in the (2i-1)th pixel column and the (2j-1)th pixel row to be input to the display panel is greater than the grayscale value of the pixel in the third image located in the second image located in the (2i-1)th pixel column and the (2j-1)th pixel row to be input to the display panel. The grayscale values ​​of the pixels in the 2i-th pixel column and the 2j-1-th pixel row to be input to the display panel in the second image are less than the grayscale values ​​of the pixels in the 2i-th pixel column and the 2j-1-th pixel row to be input to the display panel in the third image; i is greater than or equal to 1 and less than or equal to M, j is greater than or equal to 1 and less than or equal to N.

[0049] In the embodiments of this application, the grayscale values ​​of each pixel 10 located in odd pixel row 111 and odd pixel column 121 and the pixel 10 located in odd pixel row 112 and odd pixel column 122 are equal, and / or, the grayscale values ​​of each pixel 10 located in odd pixel row 111 and odd pixel column 122 and the pixel 10 located in odd pixel row 112 and odd pixel column 121 are equal.

[0050] Specifically, the grayscale value of each pixel 10 located in odd pixel row 111 and odd pixel column 121 is equal. For example, the grayscale value of each pixel 10 located in odd pixel row 111 and odd pixel column 121 is 180.

[0051] Specifically, each pixel 10 located in the idol pixel row 112 and the odd pixel column 121 has the same grayscale value. For example, the grayscale value of each pixel 10 located in the idol pixel row 112 and the odd pixel column 121 is 50.

[0052] Specifically, each pixel 10 located in odd pixel row 111 and in i pixel column 122 has the same grayscale value. For example, the grayscale value of each pixel 10 located in odd pixel row 111 and in i pixel column 122 is 50.

[0053] Specifically, each pixel 10 located in pixel row 112 and pixel column 122 has the same grayscale value. For example, the grayscale value of each pixel 10 located in pixel row 112 and pixel column 122 is 180.

[0054] In the embodiments of this application, multiple pixels 10 located in the same pixel column 12 have the same color, while multiple pixels 10 located in two adjacent pixel columns 12 have different colors. For example, multiple pixels 10 in odd pixel column 121 are all red pixels 10, multiple pixels 10 in the adjacent odd pixel column 122 are all green pixels 10, and multiple pixels 10 in another odd pixel column 121 adjacent to the odd pixel column 122 are all blue pixels 10.

[0055] In embodiments of this application, the number of odd pixel rows 111 is equal to the number of odd pixel rows 112. For example, if the display panel includes 2N pixel rows 11, then the display panel includes N odd pixel rows 111 and N odd pixel rows 112. The value of N can be, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, etc.

[0056] In embodiments of this application, the number of odd pixel rows 121 is equal to the number of i-pixel rows 122. For example, if odd pixel row 111 includes 2M pixels 10, then i-pixel row 112 also includes 2M pixels 10. The value of M can be, for example, 3, 6, 9, 12, 30, 60, 90, 120, 300, 600, 900, 1200, etc.

[0057] In an embodiment of this application, the display panel includes a gate driving circuit, which includes a cascaded first gate driving unit (GOA1, GOA3, GOA5, etc.) and a second gate driving unit (GOA2, GOA4, GOA6, etc.). The first gate driving unit (GOA1, GOA3, GOA5, etc.) is connected to a first clock signal (CK1, CK3, CK5, etc.) and electrically connected to a plurality of pixels 10 in odd pixel row 111 through scan line G. The second gate driving unit (GOA2, GOA4, GOA6, etc.) is connected to a second clock signal (CK2, CK4, CK6, etc.) and electrically connected to a plurality of pixels 10 in odd pixel row 112 through scan line G.

[0058] In the embodiments of this application, the time difference between two adjacent first gate driving units (GOA1, GOA3, GOA5, etc.) receiving the first clock signal (CK1, CK3, CK5, etc.) is equal to the time difference between two adjacent second gate driving units (GOA2, GOA4, GOA6, etc.) receiving the first clock signal (CK1, CK3, CK5, etc.).

[0059] In the embodiments of this application, the time difference between two adjacent first gate driving units (GOA1, GOA3, GOA5, etc.) and the first clock signal (CK1, CK3, CK5, etc.) is between 2 microseconds and 3 microseconds. Specifically, the time difference between two adjacent first gate driving units (GOA1, GOA3, GOA5, etc.) and the first clock signal (CK1, CK3, CK5, etc.) includes 2 microseconds, 2.05 microseconds, 2.1 microseconds, 2.15 microseconds, 2.2 microseconds, 2.25 microseconds, 2.3 microseconds, 2.35 microseconds, 2.4 microseconds, 2.45 microseconds, 2.5 microseconds, 2.55 microseconds, 2.6 microseconds, 2.65 microseconds, 2.7 microseconds, 2.75 microseconds, 2.8 microseconds, 2.85 microseconds, 2.9 microseconds, 2.95 microseconds, and 3 microseconds. Preferably, the time difference between the first clock signal (CK1, CK3, CK5, etc.) for two adjacent first gate driving units (GOA1, GOA3, GOA5, etc.) is 2.47 microseconds.

[0060] In the embodiments of this application, the duration for which the first clock signal (CK1, CK3, CK5, etc.) remains at a high potential is equal to the duration for which the second clock signal (CK2, CK4, CK6, etc.) remains at a high potential. Specifically, the duration for which the first clock signal (CK1, CK3, CK5, etc.) remains at a high potential is greater than 3 microseconds and less than or equal to 9 microseconds. Specifically, the values ​​for the duration for which the first clock signal (CK1, CK3, CK5, etc.) remains at a high potential include 3.5 microseconds, 4 microseconds, 4.5 microseconds, 5 microseconds, 5.5 microseconds, 6 microseconds, 6.5 microseconds, 7 microseconds, 7.5 microseconds, 8 microseconds, 8.5 microseconds, and 9 microseconds. Specifically, the duration for which the first clock signal (CK1, CK3, CK5, etc.) remains at a high potential is equal to P times the time difference between the access of two adjacent first gate driving units (GOA1, GOA3, GOA5, etc.) to the first clock signal (CK1, CK3, CK5, etc.), where P is a positive integer greater than or equal to 1. The value of P includes 1, 2, 3, 4, 5, etc. Preferably, the duration for which the first clock signal (CK1, CK3, CK5, etc.) is kept at a high potential and the duration for which the second clock signal (CK2, CK4, CK6, etc.) is kept at a high potential are both 7.41 microseconds.

[0061] In the embodiments of this application, multiple first gate driving units (GOA1, GOA3, GOA5, etc.) are electrically connected to multiple odd pixel rows 111 in a one-to-one correspondence through multiple scan lines G. In the second frame, the first first gate driving units (GOA1, GOA3, GOA5, etc.) arranged along the first direction Y to the Kth first gate driving units (GOA1, GOA3, GOA5, etc.) are sequentially connected to the first clock signal (CK1, CK3, CK5, etc.), and multiple pixels 10 in the first odd pixel row 111 arranged along the first direction Y to multiple pixels 10 in the Kth odd pixel row 111 are sequentially turned on. In the third frame, the first second gate driving unit (GOA2, GOA4, GOA6, etc.) arranged from the first first gate driving unit (GOA1, GOA3, GOA5, etc.) to the Kth first gate driving unit (GOA1, GOA3, GOA5, etc.) are sequentially connected to the second clock signal (CK2, CK4, CK6, etc.), and multiple pixels 10 in the first pixel row 112 arranged from the first first gate driving unit (GOA1, GOA3, GOA5, etc.) to the Kth first gate driving unit (GOA1, GOA3, GOA5, etc.) are sequentially turned on.

[0062] like Figure 1 and Figure 2As shown, multiple first gate driving units (GOA1, GOA3, GOA5, etc.) are electrically connected to multiple odd pixel rows 111 one-to-one through multiple scan lines G. In the second frame, the first first gate driving units (GOA1, GOA3, GOA5, etc.) arranged along the first direction Y to the Kth first gate driving units (GOA1, GOA3, GOA5, etc.) are sequentially connected to the first clock signal (CK1, CK3, CK5, etc.), and multiple pixels 10 in the first odd pixel row 111 arranged along the first direction Y to multiple pixels 10 in the Kth odd pixel row 111 are sequentially turned on. In the third frame, the first second gate driving units (GOA2, GOA4, GOA6, etc.) arranged from the Kth first gate driving unit (GOA1, GOA3, GOA5, etc.) toward the first first gate driving unit (GOA1, GOA3, GOA5, etc.) are sequentially connected to the second clock signal (CK2, CK4, CK6, etc.). Furthermore, multiple pixels 10 in the first pixel row 112 arranged from the Kth first gate driving unit (GOA1, GOA3, GOA5, etc.) toward the first first gate driving unit (GOA1, GOA3, GOA5, etc.) are sequentially turned on. K is a positive integer greater than or equal to 2.

[0063] The gate driving circuit is configured to sequentially output multiple scan signals to multiple odd pixel rows during the first driving cycle, and to not output the scan signals to the odd pixel rows during the first driving cycle. The gate driving circuit is also configured to sequentially output multiple scan signals to multiple odd pixel rows during the second driving cycle, and to not output the scan signals to the odd pixel rows during the second driving cycle.

[0064] The source drive circuit is used to output multiple second grayscale data of the second image to the pixels of the multiple odd pixel rows during the first drive cycle, and to output multiple third grayscale data of the third image to the pixels of the multiple odd pixel rows during the second drive cycle.

[0065] like Figure 1 and Figure 5As shown, before the refresh rate switch, the timing controller drives the display panel to display the original image, that is, to activate multiple pixels 10 in each odd pixel row 111 and multiple pixels 10 in each i-pixel row 112 within the time of one frame F. After the refresh rate switch, the timing controller drives the display panel to sequentially display the second image and the third image generated based on the original image, that is, to activate multiple pixels 10 in each odd pixel row 111 row by row within the time of the second image F1, and to activate multiple pixels 10 in each i-pixel row 112 row by row within the time of the third image F2. The activation time of each pixel row 11 is the same. Before the refresh rate switch, the time for the timing controller to drive the display panel to display one frame (original image, first image) F is equal to the total time for the timing controller to drive the display panel to display two frames (second image F1 and third image F2) after the refresh rate switch. Specifically, the refresh rate of the display panel 110 is switched from a first refresh rate to a second refresh rate, for example, the first refresh rate is 60 Hz and the second refresh rate is 120 Hz. Among them, the screen (original screen, first screen) F displayed at the first refresh rate is a heavy screen, while the second screen F1 and the third screen F2 displayed at the second refresh rate are both light screens.

[0066] In the display device provided in this application, a first frame is generated from an original frame using viewing angle compensation (VAC) technology, and a second frame and a third frame are generated from the first frame after viewing angle compensation. The second grayscale data of the second frame includes the grayscale data of pixels in the odd-pixel rows of the first frame to be input to the display panel. The third grayscale data of the third frame includes the grayscale data of pixels in the odd-pixel rows of the first frame to be input to the display panel. During a first driving cycle when the display panel displays the second frame, pixels in multiple odd-pixel rows are sequentially activated row by row. During a second driving cycle when the display panel displays the third frame, pixels in multiple odd-pixel rows are sequentially activated row by row. Therefore, the display device provided in this application can, under the premise of compensating for viewing angle (VAC function enabled), make the grayscale value of the grayscale data displayed in each second frame of the screen change less, and make the grayscale value of the grayscale data displayed in each third frame of the screen change less. That is, in the driving cycle of one frame of the screen (first driving cycle, second driving cycle), the grayscale data transmitted by one data line flips less, thereby avoiding frequent and large changes in the grayscale value of the grayscale data input to the odd pixel row and the odd pixel row when the display panel displays one frame of the screen (large grayscale data flip), thereby reducing the load of the display device and the power consumption when the VAC function is enabled.

[0070] Step 603: Generate a second frame and a third frame based on a first frame, wherein the second grayscale data of the second frame includes the grayscale data of the pixels in the odd-pixel rows of the first frame to be input to the display panel, and the third grayscale data of the third frame includes the grayscale data of the pixels in the odd-pixel rows of the first frame to be input to the display panel; and

[0071] Step 604: Within the first driving cycle and the second driving cycle, display one frame of the second image and one frame of the third image sequentially, wherein the first driving cycle and the second driving cycle are two driving cycles that are consecutive in time, and the sum of the first driving cycle and the second driving cycle is equal to the driving cycle of one frame of the original image. The first driving cycle is the driving cycle for the display panel to display the second image, and the second driving cycle is the driving cycle for the display panel to display the third image.

[0072] The sequential display of one frame of the second image and one frame of the third image within the first driving cycle and the second driving cycle includes:

[0075] During the second driving cycle, the pixels of the plurality of said idol rows are activated row by row; and

[0076] During the second driving cycle, the third grayscale data is output to the pixels of the plurality of said idol rows.

The seventh grayscale value of the grayscale data of the pixel located in the 2i-th pixel column and the 2j-th pixel row of the first image to be input to the display panel is greater than the eighth grayscale value of the grayscale data of the pixel located in the 2i-th pixel column and the 2j-th pixel row of the original image to be input to the display panel. i is greater than or equal to 1 and less than or equal to M, and j is greater than or equal to 1 and less than or equal to N.

[0120] In the display device and driving method provided in this application, a first frame is generated from an original frame using viewing angle compensation (VAC) technology, and a second frame and a third frame are generated from the first frame after viewing angle compensation. The second grayscale data of the second frame includes the grayscale data of pixels in the odd-pixel rows of the first frame to be input to the display panel. The third grayscale data of the third frame includes the grayscale data of pixels in the odd-pixel rows of the first frame to be input to the display panel. During a first driving cycle when the display panel displays the second frame, pixels in multiple odd-pixel rows are sequentially activated row by row. During a second driving cycle when the display panel displays the third frame, pixels in multiple odd-pixel rows are sequentially activated row by row. Therefore, the display device provided in this application can, under the premise of compensating for the viewing angle (VAC function enabled), make the grayscale value of the grayscale data displayed in each second frame of the screen change less, and make the grayscale value of the grayscale data displayed in each third frame of the screen change less. That is, in the driving cycle of a frame of the screen (first driving cycle, second driving cycle), the grayscale data transmitted by a data line flips less, thereby avoiding frequent and large changes in the grayscale value of the grayscale data input to the odd pixel row and the odd pixel row when the display panel displays a frame of the screen (large grayscale data flip), thereby reducing the load of the display device and the power consumption when the VAC function is enabled.

[0121] The above provides a detailed description of a display device and its driving method according to the embodiments of this application. The description of the above embodiments is only for the purpose of helping to understand the core ideas of this application, and the above description should not be construed as a limitation on the scope of protection of this application.
