Abstract

The invention discloses a drive circuit and a display device. The level conversion drive circuit comprises a generation module which is used for generating image data; a control module is used for judging whether the generation module updates the image data or not; a time sequence module is used for displaying a picture based on the image data; and if the generation module updates the image data and the picture corresponding to the updated image data is overlapped with the picture corresponding to the image data before updating, the time sequence module stops displaying the picture corresponding to the image data before updating and displays the picture corresponding to the updated image data. According to the invention, the picture corresponding to the updated image data can be prevented from overlapping with the picture corresponding to the image data before updating, so that the visual angle can be improved, a flicker phenomenon cannot be generated in a time domain operation mode, and the display effect of the display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving circuit and a display device. Background technique [0002] When the resolution of the display device is gradually increased, and currently reaches above 8K (7680x4320), when the size of the display panel remains unchanged, the impact of the increase in resolution is that the aperture ratio is reduced, thereby reducing the penetration of the display panel. Rate. Therefore, the original viewing angle improvement solution - 8-domain pixel architecture design cannot be applied in higher resolution products due to the loss of penetration rate. It is replaced by a 4-domain pixel architecture, but it also leads to deterioration of viewing angle characteristics, which requires viewing angle compensation and improvement. viewing angle characteristics. [0003] The existing viewing angle improvement method is generally to distinguish the H and L states of the pixels...
