Embodiment Construction

[0038] The invention provides a driving circuit and method of a display panel. This method is used to improve the disadvantage of display coupling effect in the prior art, and at the same time, it can improve the uniformity of the display picture.

[0039] figure 2 It is a block diagram of the driving circuit of the display panel of the present invention. like figure 2 As shown, the drive circuit 200 includes a frequency controller 202, at least one first gate drive chip 204, a first gate line 206, at least one second gate drive chip 208, a second gate line 210 and a processing circuit 212 . The first gate lines 206 and the second gate lines 210 are disposed on the display panel 214 at intervals, and are electrically connected to the first gate driving chip 204 and the second gate driving chip 208 respectively. The frequency controller 202 generates a frequency signal 216, the first gate drive chip 204 is connected to the frequency controller 202, and the first gate driv...

Abstract

A method for driving display face plate includes inputting the first driving signal to multiple first grid line on display face plate in sequence from the first direction and simultaneously inputting the second driving signal to multiple second grid line on display face plate in sequence from the second direction opposite to the first one, regulating the driving time of the first driving signal to difference driving time of two said grid lines when two said driving signals are separately inputted to two said grid lines being set in adjacent arrangement.

Description

technical field [0001] The present invention relates to a driving circuit and a method of a display panel; specifically, the present invention relates to a driving circuit and a method of a display panel with improved coupling effect. Background technique [0002] Flat panel displays have the advantages of thinness, low power consumption, and low radiation, and have gradually replaced traditional CRT displays. Flat panel displays include plasma displays and liquid crystal displays, etc. However, liquid crystal displays have gradually caught up with plasma displays in terms of panel size and color performance. [0003] In order to improve the color performance of LCD monitors, figure 1 It is a block diagram of a conventional display panel driving circuit. like figure 1 As shown, the known technology uses a first gate driver chip 102 and a second gate driver chip 104 respectively arranged on both sides of the display panel 100, the first gate driver chip 102 is respectively...
