[0080] Such as Figure 9A As shown in , it is the first timing diagram of the driving method of the display device according to the embodiment of the present application. In this embodiment, the first scan line group includes 4n-3 scan lines and 4n-2 scan lines, such as scan lines S1, S2, S5, S6, S9, S10; the second scan line group includes 4n- 1 scan line and 4n-2th scan line, such as S3, S4, S7, S8, S11, S12. Wherein, n is a positive integer greater than or equal to 1 and less than or equal to m, m is an integer greater than or equal to 1, and the sum of the total number of scanning lines in the first scanning line group and the second scanning line group is 4m. In the first 1 / 2 frame, clock signal lines CK1, CK2, CK5, CK6, CK9, and CK10 output clock signals in sequence, so that scanning signals G1, G2, G5, G6, G9, and G10 are output in sequence, and each data line is The polarity of the transmitted data signal remains unchanged at this stage. Enter the vertical blank per...

Abstract

The invention provides a display device and a driving method thereof, and the method comprises the following steps: scanning the scanning lines in a first scanning line group at the first 1 / 2 frame, enabling the same data line to input a data signal with the same polarity, and enabling the polarities of data signals input by two adjacent data lines to be opposite; at post 1 / 2 frames, scanning thescanning lines of the second scanning line group, wherein the polarity of a data signal input by each data line is opposite to the polarity of a data signal input by the same data line in the first 1 / 2 frame, the first scanning line group comprises a 4n-3 scanning line and a 4n-2 scanning line, the second scanning line group comprises a 4n-1 scanning line and a 4n scanning line, n is greater thanor equal to 1 and less than or equal to m, and n and m are integers; or the first scanning line group comprises a 12n-11th scanning line, a 12n-8th scanning line, a 12n-7th scanning line, a 12n-4th scanning line, a 12n-3th scanning line and a 12n-th scanning line; the second scanning line group comprises 12n-10th scanning lines, 12n-9th scanning lines, 12n-6th scanning lines, 12n-5th scanning lines, 12n-2th scanning lines and 12n-1th scanning lines, n is greater than or equal to 1 and less than or equal to m, and n and m are integers.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a driving method thereof. Background technique [0002] Currently, as the resolution of the display device is gradually increased, the resolution of the display device has reached 8K (7680×4320). For an 8K display device with a 1G1D architecture, the temperature rise and the power consumption of the source driver are accompanied by the problem of high power consumption. And if Figure 3-Figure 4 as shown, image 3 It is a schematic diagram of vertical stripes appearing in a traditional 1G1D architecture display device using column inversion driving, Figure 4 It is a schematic diagram of diagonal stripes appearing when column inversion driving is adopted in a traditional flip pixel (Flip pixel) architecture display device, represented by image 3 It can be seen that when a 1G1D structure display device adopts column inversion, the polarities of ...
