Display panel and patching method thereof

Abstract

The invention provides a display panel and a patching method thereof, which are suitable for the field of display panels. The display panel comprises a plurality of signal wires, at least one first patching wire and at least one second patching wire, wherein the first patching wire and the second patching wire are respectively arranged both relative sides of the signal wires and respectively partly overlapped with the signal wires. The patching method of the display panel comprises the following steps: electrically connecting the rupturing signal wires and the first patching wire; electrically connecting the rupturing signal wires and the second patching wire; and utilizing a flexible conductive component to electrically connect the first patching wire and the second patching wire. The display panel and the patching method thereof can be used for patching the signal wires to prevent the display panel from being directly damaged and lead to the low transmission impedance of signals after the signal wires are patched, thereby ensuring the signal transmission quality and the patching success ratio of the signal wires.

Description

technical field [0001] The invention belongs to the field of display panels, in particular to a display panel capable of ensuring signal quality after repair and a repair method thereof. Background technique [0002] A common display panel, such as a Liquid Crystal Display (LCD) panel, has a glass lower substrate. A plurality of pixel circuits and a plurality of signal lines (such as scanning lines and data lines) are formed on the lower glass substrate. Each pixel receives corresponding control signals (such as scanning signals and pixel voltages) through corresponding signal lines, so these signal lines and pixel circuits can form a display area on the lower glass substrate. [0003] In addition, multiple Repair Lines, or Rescue Lines, may be provided on the lower glass substrate. These repair lines are partly formed on the lower glass substrate, and partly overlap these signal lines, that is, part of the repair lines and signal lines intersect each other up and down, an...

Problems solved by technology

[0004] However, when part of the repair line is formed on the lower glass substrate to transmit signals, the impedance of the repair line on the lower glass substrate is too large, which is likely to cause resistance-capacitance delay effect (RC delay), resulting in signal delay, so the repair line The repair function cannot be completed normally, so that the panel cannot be repaired and must be scrapped, thereby increasing the production cost
