Assignee: AUO CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A display panel, comprising:
a data line; and
a pixel circuit under test, coupled to the data line, and configured to receive a first detecting signal from a detecting signal source and receive a second detecting signal from a pixel data signal source, wherein the 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, wherein the pixel circuit under test comprises:
a luminous element, configured to emit a light according to the driving current;
a bypass circuit, coupled to the luminous element and the data line, and configured to transmit the detection result signal to the detecting signal source through the data line according to a test control signal so that the detecting signal source determines whether the pixel circuit under test is abnormal; and
a pulse-width modulation circuit, coupled to the detecting signal source and a first control signal source, and configured to drive according to a first control signal of the first control signal source.
