ARRAY TEST DEVICE AND ARRAY TEST METHOD FOR DISPLAY PANEL

摘要

An array test device for a display panel includes a stage on which the display panel including a plurality of pixel circuits is disposed, a contact unit including a plurality of probe pins, an adjustment unit which adjusts the contact unit such that the probe pins contact a plurality of pads of the display panel, and a testing unit which applies an array test signal to the pixel circuits of the display panel through the probe pins and the pads, receives a test result signal from the pixel circuits through the pads and the probe pins, generates waveform information representing a waveform of the test result signal, and determines whether the pixel circuits are defective based on the waveform information.
