Abstract

A display panel includes a data line and a pixel circuit under test. Pixel circuit under test is coupled to data line, and is configured to receive a first detecting signal from a detecting signal source and receive a second detecting signal from a pixel data signal source. Pixel circuit under test is configured to generate a driving current to read the first detecting signal and the second detecting signal so as to generate a detection result signal. Pixel circuit under test includes a luminous element and a bypass circuit. Luminous element is configured to emit a light according to the driving current. Bypass circuit is coupled to luminous element and data line, and is configured to transmit the detection result signal to detecting signal source through data line according to a test control signal so that detecting signal source determines whether pixel circuit under test is abnormal.
