An auto probe unit is provided to contact a needle to a shorting bar having a large width and a long length, thereby significantly reducing connection faults between the needle and a panel driving IC during an image quality test and exactly performing the image quality test. A TCP(Tape Carrier Package)(130) transmits an inputted test signal. To one side of a panel driving IC(Integrated Circuit)(140), plural channels are attached. The panel driving IC supplies the test signal, transmitted through the TCP, to a tested display panel(200) through the channels. Plural shorting bars(150-1,150-2,150-3) are commonly connected with corresponding channels among channels of the panel driving IC. A needle(160) is selectively contacted with one shorting bar among the shorting bars to connect the panel driving IC with the tested display panel. |
