Embodiment Construction

[0024] figure 1 It is a schematic top view of the pixel array 10 in the display panel according to an embodiment of the present invention. The display panel 10 has a display area AA and a non-display area PA surrounding the display area AA. A pixel array composed of a plurality of data lines DL, a plurality of scan lines SL and a plurality of pixel structures P is arranged in the display area AA. On the other hand, there are a gate driving device GD and a source driving device SD in the non-display area PA of the display panel 10 .

[0025] Please refer to figure 1 , in this embodiment, the scan line SL and the data line DL are arranged across each other, and an insulating layer is sandwiched between the scan line SL and the data line DL. In other words, the extending direction of the scan lines SL is not parallel to the extending direction of the data lines DL. Preferably, the extending direction of the scan lines SL is perpendicular to the extending direction of the data ...

Abstract

The invention provides a method for driving a display panel, which includes providing a display panel with a plurality of pixel structures. The frame period (frame period) of each pixel structure is divided into a first frame period and a second frame period, when the first frame period is applied, the first voltage is applied to the pixel structure, and when the second frame period is applied, the A second voltage is given to the pixel structure, and the first voltage is different from the second voltage. The gray scale range of the display panel is sequentially divided into a first gray scale area, a second gray scale area, a third gray scale area and a fourth gray scale area. In the first gray-scale area and the third gray-scale area, the difference between the first voltage and the second voltage increases as the gray-scale value increases. In the second gray scale area and the fourth gray scale area, the difference between the first voltage and the second voltage decreases as the gray scale value increases.

Description

technical field [0001] The present invention relates to a driving method, and in particular to a driving method of a display panel. Background technique [0002] With the advancement of science and technology, the technology of the display is also constantly developing. Light, thin, short and small flat panel displays (FlatPanel Display, FPD) are gradually replacing the traditional heavy cathode picture tube displays (Cathode Ray Tube, CRT). In the current display products, in order to solve the situation of color washout at the side view angle, the pixel unit corresponding to one color is spatially divided into two regions, and through appropriate circuit design, the same grayscale Different pixel voltages are applied to the two areas in the pixel unit to form two different luminances in the two areas, thereby improving the problem of color washout when measuring the angle of view. [0003] However, in recent years, due to people's pursuit of high image quality and high r...
