a LCD Module PCB Inspection Apparatus and the LCD Display Signal Inspection Method

摘要

A testing device of an LCD module PCB(printed circuit board) and a testing method of a display signal are provided to reduce a cost for the testing device of an LCD module PCB by automatically testing a display signal without using a panel assembly with a large volume. A loading jig(10) loads an LCD module PCB(50). A personal computer(30) tests electric characteristics such as a voltage, a current, resistance, a waveform of the LCD module PCB through a testing program. A display signal inspector(60) tests a display signal. A relay board(20), between the loading jig, the personal computer and the display signal inspector, supplies various test signals supplied from the LCD module PCB loaded on the loading jig to the display signal inspector and the personal computer.
