Liquid crystal panel testing device

Abstract

An inspection device for a liquid crystal panel, which is an inspection device for a liquid crystal panel in which a probe (2) of a probe block (1) is brought into contact with a conductive pattern (4) for a terminal of an array glass (3) for a liquid crystal panel for inspection Among them, when the probe block (1) is based on the maximum number of functional lines (F) and signal lines (S) made according to the required specifications of the liquid crystal panel to form the basic terminal conductive pattern (4S), it corresponds to the overall The mode of each wiring forms a plurality of insertion holes (16) for inserting the probes (2), and through inserting the probes (2) in the plurality of insertion holes (16), and forming the array glass ( The terminal of 3) is constituted by the insertion hole (16) in which the wirings of the conductive pattern (4) coincide, while the insertion hole (16) where the probe (2) is not inserted remains empty.

Description

technical field [0001] The present invention relates to an inspection device for a liquid crystal panel that inspects the short-circuit state, open state, TFT characteristics, and pixel characteristics of a conductive pattern printed on an array glass for a liquid crystal panel. Background technique [0002] like Figure 8 As shown, a general inspection device for liquid crystal panels is configured such that the probes 2 of the probe block 1 are brought into contact with the conductive pattern 4 for terminals of the array glass 3 for liquid crystal panels, and the probes 2, one end side The flexible substrate 5 connected to the probe 2 and the relay substrate 6 connected to the other end side of the flexible substrate 5 read the signal from the conductive pattern 4 for the terminal by the detector main body 7. Perform TFT (Thin Film Transistor, Thin Film Transistor) and pixel characteristic inspection. [0003] In this case, the flexible substrate 5 is composed of a flexib...

AI Technical Summary

Problems solved by technology

[0022] Therefore, the existing inspection equipment for liquid crystal panels cannot mass-produce probe blocks, flexible substrates, and interposer substrates. Since the conductive pattern for terminals of the array glass for liquid crystal panels that is the object to be inspected must be connected each time Consistent to re-manufacture, resulting in increased manufacturing costs, extended manufacturing time and complicated manufacturing process and other issues
