Driving circuit, working method thereof and display device

Abstract

The invention discloses a driving circuit, a working method thereof and a display device, which relate to the technical field of display and aims at solving the problem that after a test signal line for lighting test is removed in the prior art, retained signal leads easily lead to abnormal display of a display substrate. The driving circuit comprises multiple signal leads in one-to-one correspondence with signal lines in the display substrate, short circuit shielding circuits in one-to-one correspondence with the multiple signal leads and connected between the corresponding signal leads and the corresponding signal lines for conducting connection between the corresponding signal leads and the corresponding signal lines during the lighting test period and cutting off connection between thecorresponding signal leads and the corresponding signal lines during a module lighting period, and a driving chip connected with the multiple signal lines respectively for providing corresponding driving signals for multiple signal lines during the module lighting period. The driving circuit provided in the invention is used for controlling the display substrate for normal display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving circuit, a working method thereof, and a display device. Background technique [0002] With the continuous development of display technology, there are more and more types of display devices. In order to improve the production yield of display devices, multiple inspections are performed on the display devices during the production process. Taking an active matrix organic light emitting diode (English: Active-matrix organic light emitting diode, AMOLED for short) display device as an example, when making an AMOLED display device, after cutting the AMOLED motherboard to obtain multiple independent display substrates, generally A lighting test (ET test) will be performed on the display substrate to confirm the quality of the display substrate. After confirming that the display substrate is in good condition, cut off the test signal line used for the lighting test in the ...
