  • Display device and pixel testing method thereof
    Patent number: 7342410
    Abstract: A display device has a display panel, which includes a plurality of IC pads, a plurality of data lines, a selector, a plurality of switches and a test pad. The IC pads are connected to the data lines through the selector. The data lines are electrically connected to a corresponding pixel circuit. The IC pads are connected to the test pad via the corresponding switch. The switches are sequentially turned on to sequentially transmit a voltage to the corresponding pixel circuit through the test pad.
