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. The display panel comprises a control circuit board, grid electrode driving chips and an array substrate. The array substrate comprises basic wires, and the basic wires are electrically connected with the control circuit board to form two or more signal transmission paths. The signal transmission paths are used for transmitting grid electrode control signals. The two or more grid electrode driving chips are electrically connected with different signal transmission paths, and the ratio of total resistance values of the basic wires between the two grid electrode driving chips electrically connected to different signal transmission paths and the control circuit board is a preset ratio. According to the display panel, at least the time sequence difference between the two grid electrode driving chips is 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...
