Problems solved by technology
[0006] However, in the past, for aging detection, a part of the small display panel was inserted into the cartridge-type installation structure so as to be connected with the contact, which caused the problem of cracks (Crack) on the display panel during installation or removal.
[0007] Moreover, the production characteristics of small display panels require rapid production of a large number of display panels, so quick inspection is required, and the existing probe station can only inspect one display panel at a time, so it is difficult to apply to mass production
[0008] For example, Korean Patent Publication No. 2007-0072649 discloses a test device and method for liquid crystal display modules, but it cannot support the detection of a large number of display panels, so it is difficult to apply to mass production

The invention discloses a display panel detection device and method for detecting an AMOLED display panel. The display panel inspection device according to the embodiment of the present invention includes: a main body arranged on a workbench for inspecting a display panel; a pallet including a plurality of clamps arranged in sequence along the extending length direction of the support , the support is assembled on the base fixed on the body, the bottoms of the plurality of clamps are respectively equipped with contact pieces, the rod in the form of a lever lifts or lowers the clamps, so that the contact pieces correspond to the corresponding The display panel is in contact with the display panel; the rod pressing unit is arranged on the mobile body, and it descends or rises according to the input signal to make the rod move, and the mobile body can move vertically or horizontally on the body; and control The unit applies electrical signals to each channel connected to the plurality of contacts, so as to perform aging and lighting detection on each display panel.
Description
technical field [0001] The invention relates to a display panel testing device and method for testing AMOLED panels. Background technique [0002] An AMOLED panel (Active Mode Organic Light Emitting Diode Panel) is a display device that can display desired images by individually supplying data signals based on image information to pixels arranged in an active matrix (Active Matrix) format to control the pixels. [0003] AMOLED panels are characterized by lightness, thinness, low power consumption, etc., so the scope of application is gradually widening. Recently, as a device for displaying small screens, it is widely used in portable terminals, such as tablet computers, portable audio devices, and smart phones. [0004] On the one hand, panel inspection is performed in the manufacturing process of the small display panel, and an electrical signal is applied to the display panel to check whether it is working normally. In this case, the device used is a probe station. [00...
