Embodiment Construction

[0039] A specific embodiment according to the present invention is a display panel testing system. In this embodiment, the display panel testing system is used to test the display panel to be tested. In fact, the display panel to be tested is preferably a liquid crystal display panel, but not limited thereto. In addition, the size of the display panel to be tested and the circuit spacing of its integrated circuits can also be determined according to actual needs, and there is no specific limitation.

[0040] Please refer to Figure 3A and Figure 3B , Figure 3A and Figure 3B It is a schematic diagram showing the appearance and structure of the display panel testing system respectively. As shown in the figure, the display panel testing system 3 includes a testing device 30 and a micro-probe device 32 for testing signal lines and pixels of the display panel 4 to be tested. In this embodiment, the test device 30 includes a test signal generator 301 , a circuit board modul...

Abstract

The invention discloses a display panel testing system comprising a testing device and a microprobe device which are used for testing a display panel to be tested. The testing device is used for generating testing signals; the microprobe device comprises a substrate and a microprobe; the substrate is coupled with the testing device and provided with testing integrated circuits arranged symmetrically; and the microprobe is arranged on the substrate and coupled with the display panel to be tested. When being inputted into the substrate of the microprobe device and transmitted to the testing integrated circuits along a specific path, the testing signals are reversed by the testing integrated circuits and transmitted to the substrate of the microprobe device, and then the testing signals are outputted to the display panel to be tested through the microprobe.

Description

technical field [0001] The present invention is related to display panels, in particular to a micro-probe device with a monolithic substrate structure and a display panel testing system using the micro-probe device. Background technique [0002] Currently, there are various types of flat panel display devices (FPD) on the market, such as liquid crystal display devices (LCD), organic electroluminescent display devices (OLED) and plasma display devices (PDP). However, no matter what kind of flat-panel display device it is, it is necessary to test its signal lines (such as scan lines and data lines) and pixels during the manufacture of its display panel, so as to determine the flat panel produced. The display device is functioning normally. [0003] Generally speaking, the test methods of signal lines and pixels on the display panel can be roughly divided into two types: full contact probe test method and shorting bar probe test method. In the early days, the shorting bar pro...
