Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] In order to facilitate the understanding of the solutions provided in this application. The following is a brief description of the display:

[0048] A display includes a display panel and a driving circuit. Wherein, the function of the display panel is to emit light to display patterns, and the driving circuit is used to provide signals required for display by the display panel, and control the operation of the display panel through these signals.

[0049] The structure of the display panel is also different based on the type of the display. Taking a liquid crystal display as an example, the display includes a display panel and a driving circuit. The display panel includes an array substrate, a color filter substrate arranged...

Abstract

The invention discloses an anti-splash screen circuit and method, a driving circuit and a display device, and belongs to the technical field of display. The anti-splash screen circuit comprises a control sub-circuit which is configured to control a grid driving circuit of the display panel to output a grid cut-off level in a power-on time period. A gate drive circuit of a display panel is controlled to output a gate cut-off level within a power-on time period; the grid electrode cut-off level is provided for the TFT in the display panel, so that the TFT in the display panel is in a cut-off state in a power-on time period, when the TFT in the display panel is in a cut-off state, the pixel unit of the display panel does not emit light, and the phenomenon of starting up and flashing a screen is eliminated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an anti-flash screen circuit and method, a driving circuit, and a display device. Background technique [0002] With the development of display technology and the improvement of people's material level, the requirements for all aspects of the display are getting higher and higher. For existing products, eliminating various display defects is an important way to improve product quality. Most of the current liquid crystal display products have the phenomenon of splash screen (also called flash white) when starting up. Contents of the invention [0003] Embodiments of the present invention provide an anti-flicker screen circuit and method, a driving circuit, and a display device, which are used to eliminate the flicker screen phenomenon when starting up. Described technical scheme is as follows: [0004] On the one hand, an embodiment of the present invention provides an anti-...
