Abstract

The invention provides a display panel, a lighting detection device and a control method thereof, which relate to the field of display technology and are used to improve the problem that a lighting module and a lead wire group cannot be automatically and accurately aligned. The lighting detection device includes a base, a plurality of lighting modules arranged at intervals, and a control assembly connected to each of the plurality of lighting modules; each of the plurality of lighting modules includes a detection assembly, and the detection assembly It includes a first conductive probe, a second conductive probe and a processing unit. The processing unit obtains the offset of the lighting module by detecting the resistance between the first conductive probe and the second conductive probe, and converts the The offset is sent to the control component; the control component is used to drive the lighting module to move the offset.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a lighting detection device and a control method thereof. Background technique [0002] In recent years, various flat panel display devices, such as liquid crystal display devices, plasma display devices, organic light-emitting diode display devices, etc., have replaced conventional cathode Ray tube display devices have become the mainstream of display products. [0003] In the manufacturing process of flat-panel display devices, before the gate control chip and data control chip are bound to the display panel, it is necessary to use a lighting detection device to test the display panel to check whether it can work normally and whether there are bright spots or bright lines. Wait bad. [0004] A commonly used detection method is as follows: the lighting detection device shoots the alignment mark (Align Mark) on the display panel through the alignment c...
