Patent ID: 7843208

Claim:
A method for testing a display panel including a plurality of pixels, a plurality of source lines, and a plurality of gate lines, the method comprising: applying a gate test signal and a source test signal to the gate and source lines, respectively, to firstly detect defects of the display panel; and applying a first test signal and a second test signal to the first and second test parts, respectively, to secondly detect defects of the display panel, the display panel further including: a first test part electrically connected to the source lines through a first static dissipative part, a second test part electrically connected to the gate lines through a second static dissipative part, a storage voltage line receiving a common voltage, and a static discharging part being between the first static dissipative part electrically connected to the storage voltage line, and the pixels, wherein the static discharging part discharges a static charge applied to the first static dissipative part to prevent a malfunction of the pixels, wherein the first test signal from the first test part is applied to the source lines through the first static dissipative part, and the first test signal is different from the common voltage.
