Display panel and signal transmission method thereof

Abstract

The invention discloses a display panel and a signal transmission method thereof. The display panel provided by the invention comprises a substrate and at least a first driving chip and a second driving chip. The first and second driving chips are directly arranged on one side of the substrate; the first driving chip is at least provided with a first power supply receiving solder pad, first and second auxiliary solder pads and a first auxiliary wire; and the second driving chip is at least provided with a second power supply receiving solder pad. The first power supply receiving solder pad and the first auxiliary solder pad are used for receiving system voltages respectively and the first auxiliary solder pad is also connected with the second auxiliary solder pad through the first auxiliary wire to transmit the system voltage to the second power supply receiving solder pad from the second auxiliary solder pad.

Description

technical field [0001] The present invention relates to a plane display technology, and in particular to a power wiring and a signal transmission method between a plurality of gate drive chips directly arranged on a glass substrate of a liquid crystal display panel. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of flat-panel displays. Among many flat-panel displays, liquid crystal displays (LCD) have high space utilization efficiency, low power consumption, no radiation and low Superior features such as electromagnetic interference have immediately become the mainstream of the market. [0003] In recent years, in order to effectively control the production cost of liquid crystal displays, some panel manufacturers have adopted a chip-on-glass (COG) bonding process to directly connect multiple gate drive chips. It is arranged on one side of the glass substrate of the panel, thereby...

Also because of this, when the liquid crystal display is turned on and off, an excessive inrush current (inrush current) is likely to flow into the gate drive voltage V GH The power receiving pad P GH , causing the power receiving pad P GH burnt

In this way, not only will the gate driver chips 101a˜101n fail to turn on the pixels of each scanning line in the display unit 103 smoothly, but also the display unit 103 will not be able to display images for users to watch.
