Abstract

The invention discloses a display panel testing device. The device is used for testing a display panel. The device comprises a machine table, a contact pin and at least two adsorption component assemblies, wherein the machine table is used for bearing the display panel, the contact pin is used for making contact with a contact pad of the display panel so as to output a test signal to the display panel, each adsorption component assembly comprises at least one adsorption component arranged on the machine table, and the adsorption components are used for adsorbing the display panel so as to fix the display panel during display panel testing. By the adoption of the device, the display panel can stay horizontal in the testing process so that a test image displayed by the display panel in the flat state can be taken by the testing device, and a test result is made more precise.

Description

【Technical field】 [0001] The invention relates to the technical field of display panel testing, in particular to a display panel testing device. 【Background technique】 [0002] The width of the frame of the traditional display panel adopting the narrow frame technology is relatively narrow. [0003] The above-mentioned display panels generally require a lighting test. The lighting test includes a manual lighting test and an automatic lighting test. The technical solution for the automatic lighting test is: [0004] The pressing pin on the lighting machine touches the contact pad (Pad) on the display panel, so as to transmit the test signal to the display panel, and test the lighting picture, wherein, the display panel needs to be kept in a horizontal state during the automatic lighting test . [0005] In practice, the inventors found that the prior art has at least the following problems: [0006] During the automatic lighting test of the display panel, since the press pi...
