Abstract

The invention provides a display panel test device which is used for the pressure test in prepressing of a flexible circuit board and a display panel. The display panel comprises a conductive terminalarea. The flexible circuit board comprises an electric connecting area. The display panel test device comprises a fixture platform equipped with an embedded groove, a pressure sensor which is arranged in the embedded groove and a pressing part. The display panel is borne on the pressure sensor. The pressing part drives the flexible circuit board so that the electric connecting terminal of the electric connecting area and the terminal of the display panel are enabled to be pressed together, and the pressure sensor detects the pressure between the display panel and the flexible circuit board. The situation of poor contact of the display panel can be accurately judged according to the pressure value so that the misjudgment rate can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel testing device and a display panel testing method. Background technique [0002] At present, the substrates of flexible circuit board products on the market are mostly based on polyimide substrates. With the improvement of the resolution of display devices, the wiring in the external lead bonding area of ​​the panel is becoming more and more dense. Areas are becoming denser and finer. After the panel is produced, panel testing is required to determine the GOA (Gate Driver On Array) yield rate of the panel. However, due to the contact problem of the pressing fixture, it is very easy to cause poor contact of the terminal, and the pressure value cannot be accurately measured, resulting in misjudgment of the test. Contents of the invention [0003] The purpose of the present invention is to provide a display panel testing device and a display panel testing method,...
