Problems solved by technology

[0003] However, due to the resistance of the substrate traces between the two gate driver chips
This will cause timing differences between the control signal received by the latter gate driver chip and the control signal received by the previous one due to RC delay, which will cause each gate driver chip to fail to output in accordance with the proper timing.

Abstract

The invention relates to a display panel, which comprises a control circuit board, gate driving chips and an array substrate. The array substrate includes substrate routing and a substrate. The substrate has a top surface and a bottom surface. The top and bottom surfaces of the substrate form the baseboard routing for transmitting gate control signals, and thus, the ratio of total resistance between the substrate routing between at least two gate driving chips and the control circuit board is a predetermined ratio. According to the display panel provided in the invention, the timing differencebetween the two gate driving chips is at least improved, and the display accuracy of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] With the development of display technology, the global display industry has maintained steady growth, and the trend of large screen sizes has driven the development of the industry. In medium and large size display panels, generally there are more than two gate driving chips for gate driving. In order to save costs, the drive control circuits of each gate drive chip are usually fabricated on one control circuit board. The control circuit board and the gate drive chips and the gate drive chips are connected to each other through substrate wires. The control signals of the control circuit board to each gate driver chip are transmitted through the wiring on the substrate. [0003] However, due to the resistance of the substrate wiring between the two gate drive chips. This will cause timing differences between the control...
