Problems solved by technology

In this way, during testing, voltage will be supplied to misplaced pins, resulting in product damage and costly repairs
[0004] This shows that above-mentioned existing mode obviously still has inconvenience and defective, and needs to be improved
In order to solve the above problems, related fields have tried their best to find a solution, but a suitable solution has not been developed for a long time.

Abstract

The invention discloses a display device, which includes a display panel, at least a connection module and a control module. The connection module is coupled to the display panel. The connection module includes a plurality of pins. The pins include input pins and output pins, and the input pins are electrically coupled to the output pins. The control module is used for receiving detection signal and input voltage. When the control module receives the detection signal, the control module is used to transmit the detection signal to the input pin, and when the control module receives the detection signal returned by the output pin, the control module provides the input voltage according to the returned detection signal power chips.

Description

technical field [0001] The present invention relates to a display technology, and in particular to a display device and a testing method. Background technique [0002] When manufacturing a display device, once the Chip on Film (COF) process is completed, it is necessary to test the function of the display device. During the test, it is necessary to connect the control board to the connection board through the cable, and after the connection between the cable and the connection board, manually confirm whether the coupling status of the cable and the connection board is normal. [0003] If the manual judgment is wrong, the abnormal coupling condition of the cable and the connection board, such as the oblique insertion of the pins of the cable and the connection board, will exist in the display device. In this way, during the test, voltage will be supplied to misaligned pins, resulting in damage to the product and costly repairs. [0004] This shows that above-mentioned exist...
