Problems solved by technology

When the production line is abnormal, when the wiring on the gate-chip soft film package (Gate-Chipon Film, G-COF) is short-circuited with the wiring on the left side of the edge of the laser block, it will cause the gate-chip soft-film packaging (Gate-Chip on Film, G-COF) wiring is short-circuited with the red (R) / green (G) / blue (B) bus, resulting in poor gate (Gate) side wires

Abstract

The invention relates to a detection structure of a display panel and a display device. The display panel comprises a printed circuit board and a display area. The detection structure is characterizedby comprising a laser block, a plurality of signal channels and a light source signal bus, wherein the plurality of signal channels are arranged in the display area, and each signal channel is electrically connected with a grounding loop (GND), a positive polarity switch, a diode and a gasket; the light source signal bus is vertical to the signal channels; and the plurality of signal channels arecircularly electrically connected with a red light signal line, a green light signal line and a blue light signal line of the light source signal bus in sequence, through power supply of the printedcircuit board, a picture of the display area is detected, and after the detection for the picture of the display area is completed, laser cutting is carried out on the plurality of signal channels through laser acting to the laser block.

Description

Technical field [0001] The invention relates to the field of display, in particular to a detection structure of a display panel and a display device. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) is one of the main types of current flat panel displays, and has become an important display platform in modern IT and video products. The main driving principle of Thin Film Transistor Liquid Crystal Display (TFT-LCD), the system motherboard compresses red (R), green (G), and blue (B) signals, control signals and power through wires and printed circuit boards (Printed circuit board, PCB) is connected to the electronic connector (connector), the data is processed by the driver chip (Timing ControllerIC, TCONIC) on the printed circuit board (PCB), and then processed by the printed circuit board (Printed circuit board). board, PCB), through the source-chip on film (S-COF) and gate-chip on film (G-COF) connected to the display area, so that the liquid ...
