Abstract

A display panel has a substrate and a plurality of data lines disposed on the substrate for driving the display panel to display images. A plurality of optical sensors are disposed on the substrate. One side of each optical sensor is electrically connected to the data line and the other side thereof is connected to a test pad. When the optical sensor is irradiated by blazing light, the data line and the test pad are electrically connected. Thus, an open/short test of the display panel can be performed via the test pad. When the blazing light is removed, the optical sensors don't conduct and the data lines can drives the display normally to perform display operation.
