Problems solved by technology

[0003] However, before bonding the driver chip and the display panel, it is necessary to laser off the shorting bar and the wiring in the connection area (the bridge where the signal generated by the Gate IC reaches the glass end), if there are more than two wires after laser If the wiring is short-circuited, there will be G dark lines, which will affect the display results of the display panel.

Abstract

The invention discloses a display panel testing device and a display device. The display panel testing device comprises a testing signal input end, a shortcircuit gate, N unidirectional conduction assemblies and N conductive lines. A display panel testing signal which is input through the testing signal input end successively passes the shortcircuit gate, the unidirectional conduction assmelbies and the N conductive lines and is output to a display panel, thereby testing the display panel. The display panel testing device and the display device settle a problem of mutual interference of G concealed lines of the display panel in prior art.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a display panel testing device and a display device. Background technique [0002] In the production process of the existing display panel (TFT-LCD), there will be a shorting bar testing (Shorting BarTesting) program, the testing principle is to inject a test signal into the test circuit of the display panel to light up the panel, and generate some Simple test screen, if there are defects on the panel (such as black dots, colored dots, dashed lines and uneven gray levels, etc.), the defects will be displayed on these screens, and then the defective panels will be detected by manual or automatic defect detection system to ensure Unqualified products do not enter the next IC binding process, avoid unnecessary waste of driver chips (IC) and anisotropic conductive film (ACF) and other materials, improve the pass rate of display panel products, and reduce material consumption ...
