Abstract
The present disclosure provides a driver circuit and its working method and a display device. The driver circuit includes: a driver chip coupled with a plurality of signal lines; a plurality of signal line leads that are corresponding to the plurality of signal lines in a one-to-one manner; and a plurality of short-circuit shielding circuits that are corresponding to the plurality of signal line leads in a one-to-one manner. Each of the plurality of short-circuit shielding circuits is coupled between corresponding one of the plurality of signal line leads and corresponding one of the plurality of signal lines, and is configured to turn on or off a connection between the corresponding one of the plurality of signal line leads and the corresponding one of the plurality of signal lines.
