摘要： Provided are a driver circuit, a light-emitting panel and a preparation method thereof, and a display device. The driver circuit includes a terminal connection module, a drive module, and a short-circuit protection module. The terminal connection module, the drive module, and the short-circuit protection module are connected in series between a first power supply terminal and a second power supply terminal, and the short-circuit protection module is connected in series between the terminal connection module and the second power supply terminal. The terminal connection module is connected to an original light-emitting unit so that the original light-emitting unit is connected in series between the first power supply terminal and the second power supply terminal. The short-circuit protection module is configured to be disconnected in a case where the original light-emitting unit is short-circuited.
