Abstract

The invention discloses a detection device and a detection method of a display panel GOA circuit, for solving the problems that in the detection of the display panel GOA circuit in the prior art, a display panel needs to be lighted and manual judgment is needed, so that the efficiency is low and wrong judgment is easily made. The detection device comprises a signal providing unit used for providing a test signal to the GOA circuit, and an obtaining unit used for determining that whether GOA units in a GOA unit group of the GOA circuit have output signals or not, and if so, the output signals of the GOA units in the GOA unit group of the GOA circuit are obtained; the GOA unit group at least comprises a head end GOA unit and a tail end GOA unit of the GOA circuit; the detection device further comprises a processing unit used for comparing the obtained output signals of the GOA units in the GOA unit group and determining that whether the GOA circuit is abnormal or not according to the comparative result.

Description

technical field [0001] The invention relates to the technical field of detection of display panels, in particular to a detection device and a detection method of a GOA circuit of a display panel. Background technique [0002] GOA (Gate Driver on Array, array substrate row drive technology), is a process technology that directly manufactures the gate driver IC (Gate driver IC) on the array (Array) substrate instead of the driver chip made of external silicon chips. . The application of this technology can reduce production process procedures, reduce product process costs, and improve the high integration of TFT-LCD (Thin Film Field Effect Transistor Liquid Crystal Display) panels. [0003] In recent years, GOA technology has been fully developed and widely used. According to the distribution of GOA units, GOA panels can be divided into single-sided GOA panels (manufacturing GOA units on the left side of the array substrate) and double-sided GOA panels (making GOA units on t...
