TEST DEVICE OF GATE DRIVER AND OPERATION METHOD FOR THEREOF

摘要

A test device of a gate driver according to an embodiment of the present invention includes: a display panel where a plurality of gate lines and a plurality of data lines are arranged as crossing each other; the gate driver which outputs a plurality of gate signals to the gate lines in sequence; a plurality of parasitic capacitors which is formed in an area where the gate lines and the data lines cross each other, and charges a parasitic voltage corresponding the gate signals; and a measurement instrument which receives the parasitic voltages through the data lines, and detects whether the gate lines are normal or not on the basis of the parasitic voltages.
