Abstract

The invention discloses a display panel and a test method thereof. According to the display panel, a control switch is arranged between a test connection pad and a signal circuit; when a module lighting test is carried out, the control switch is controlled to be switched off, so that the problem of short circuit of a signal circuit during the module lighting test caused by short circuit of two ormore test connection pads due to the fact that a conductive adhesive is coated on the test connection pads is avoided, and the damage to the circuit due to large current caused by the short circuit isalso avoided; besides, a switch connection pad connected with the control end of the control switch is further arranged, so that when the jig is used for CT testing, the jig is connected with the control end to control the control switch to be connected, a signal circuit is connected with the test connection pad, and smooth CT testing is guaranteed.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a testing method thereof. Background technique [0002] With the development of display technology, LCD display panels have been widely used. In the existing TFT-LCD Full InCell display panels, the VCOM electrodes on the TFT Array side are generally used as the touch layer, in order to prevent static electricity from interfering with the liquid crystal deflection in the panel. , and does not affect the detection of finger signals by the touch layer, a layer of antistatic film will be prepared on the color filter layer away from the surface, and then the antistatic film and the grounding pad (Ag Pad) will be connected by conductive glue (Ag glue). connection (the ground pad is grounded). Therefore, if there is static electricity accumulated on the back of the color filter glass, the static electricity can be grounded through the antistatic fil...
