Problems solved by technology

Since n pole drive circuits 16 are arranged outside the same side of the pixel matrix 12, the width Z of the frame (boarder) of the display panel 10 must be at least greater than the unit width X of the gate driver module 16, which will cause the frame of the display panel 10 Cannot be elastically scaled down according to actual needs

Abstract

The invention discloses a gate drive circuit and a setting method thereof, which are suitable for a plurality of serially connected gate drive modules arranged near a special region. The setting method comprises the steps of: arranging a first gate drive module outside the first side of the special region; arranging at least two serially connected gate drive modules outside the second side corresponding to the first side of the special region; and arranging a fourth gate drive module outside the first side, wherein the second gate drive module is one of the at least two serially connected gate drive modules, the third gate drive module is the last one of the at least two serially connected gate drive module, the output end of eh first gate drive module is electrically coupled to the second gate drive module, and the output end of the third gate drive module is electrically coupled to the fourth gate drive module.

Description

technical field [0001] The present invention relates to a gate driver circuit (gate driver) of a display panel and an arrangement method thereof, and in particular relates to a method of arranging a plurality of gate driver modules on both sides of the display panel. The gate drive circuit and its setting method. Background technique [0002] see figure 1 , which shows a schematic structural diagram of a known display panel. The display panel 10 mainly includes a pixel array (pixel array) 12 and a gate driving circuit 14 , wherein the gate driving circuit 14 is disposed outside one side of the pixel array 12 . The gate driving circuit 12 includes n gate driving modules 16 and each gate driving module 16 is used to control one of its corresponding n gate lines (not shown) on the pixel matrix 12 . The n gate driving modules 16 are connected in series to transmit driving signals one by one. Furthermore, the gate driving module 16 is mainly composed of a shift register (SR) ...
