LIQUID CRYSTAL DISPLAY PANEL TESTING DEVICE AND TESTING METHOD THEREOF

摘要

An apparatus and a method for inspecting a liquid crystal panel are provided to supply a test power signal driving the liquid crystal panel in an anti static-electricity circuit of the liquid crystal panel to prevent a defective inspection due to a defective contact between a liquid crystal panel and an inspection probe. At least one probe(100) includes a plurality of connection pins respectively connected to a gate line, a data line, and a storage voltage supply line connected to an anti static-electricity circuit of a liquid crystal panel. A tape carrier package generates and supplies a test driving signal to the probe. A printed circuit board includes a power unit and a timing controller supplying a power signal and a control signal to the tape carrier package. The power unit supplies a test power signal to the storage voltage supply line.
