Problems solved by technology

In the current 8K TV panel, in order to reduce the load on the source driver (S / D, source driver) under the existing drive architecture, the data line of the panel is cut from the middle, and the upper half is provided with the charging voltage by the upper source driver. The lower part is provided with charging voltage by the lower source driver. However, due to the inconsistency between the gray scale voltage (gamma voltages) and the voltage attenuation on the source line, a line will be generated at the position of the cutting line, that is, the middle position in the horizontal direction of the panel. Horizontal line, called uneven cutting in the industry

Abstract

The invention provides a driving method of a display panel, a driving device, and a display device. The display panel comprises two-source driver units, which are disposed on the two opposite sides of the display panel, and the two-source driver units are connected with the data lines of the display panel in an up-down alternate way, or a left-right alternate way. During display driving, under control of a processor, input signals of a system end are output as data signals and control signals. According to the data signals, the two-source driver units are used to charge the correspondingly connected data lines of the display panel, and finally, according to the control signals, gate driving signal input is controlled. The input signals are displayed, and during the driving display of the display panel, the two-source driver units on the two sides of the display panel are used to provide charging voltage to the correspondingly connected data lines of the display panel, and therefore a problem of non-uniform segmentation caused by gamma voltages and the inconsistent attenuation of the voltages of the data line is prevented, and the display effect of the panel is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a driving method, a driving device and a display device of a display panel. Background technique [0002] With the development of liquid crystal display technology, liquid crystal display systems are developing in the direction of large size and high resolution. At present, major manufacturers are actively developing high-resolution 8K TV panels. In the current 8K TV panel, in order to reduce the load on the source driver (S / D, source driver) under the existing drive architecture, the data line of the panel is cut from the middle, and the upper half is provided with the charging voltage by the upper source driver. The lower part is provided with charging voltage by the lower source driver. However, due to the inconsistency between the gray scale voltage (gamma voltages) and the voltage attenuation on the source line, a line will be generated at the position of the ...
