Display panel

Abstract

A display panel comprises at least two COF binding areas, at least one voltage signal end and at least one short circuit rod. Each COF binding area is correspondingly connected with a plurality of data lines, at least one voltage signal end is arranged between two adjacent COF binding areas, each short-circuit rod is connected with one voltage signal end and two COF binding areas adjacent to the voltage signal end, and the short-circuit rod comprises a first closed loop line and a second closed loop line. The first closed loop line is connected with the voltage signal end to form a first closed loop, and the second closed loop line is connected with the voltage signal end to form a second closed loop. The two ends of the short-circuit rod are connected to the voltage signal end, so that avoltage signal is input from the two ends of the voltage signal end, the data lines on the two sides connected with the COF binding area have the same signal input, the double-drive effect is achieved, the attenuation degree of the signal in the transmission process is reduced, and the risk of color cast of a display image is reduced.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel. Background technique [0002] Generally, a liquid crystal display will design a celltest pad (test pad) between two COF (Chip On Film, chip-on-film) binding areas to facilitate the inspection of the cell (liquid crystal box) process screen. Tri-gate (three-gate) architecture products can effectively save the number of chips because the number of COFs is less than that of general architecture products. However, in the existing design scheme, under the condition of the same size, the Tri-gate product has a small number of COFs, and the distance between the adjacent COF binding regions of the Tri-gate product is relatively far away, and the data line far away from the cell test pad is due to RC delay (Resistance-capacitance delay) When the attenuated voltage signal is received, the farther the signal line is from the cell test pad, the more serious t...

AI Technical Summary

Problems solved by technology

[0003] The embodiment of the present application provides a display panel to solve the problem of signal lines far away from the cell test pad due to the small number of COFs and the relatively long distance between adjacent COF binding regions in existing Tri-gate products. The received signal will be attenuated, which will cause color shift in the cell process inspection screen, which will affect the technical problem of the inspection personnel's judgment.
