DRIVER CIRCUIT, SIGNAL PROCESSING UNIT HAVING THE DRIVER CIRCUIT, METHOD FOR MANUFACTURING THE SIGNAL PROCESSING UNIT, AND DISPLAY DEVICE |
摘要 |
Disclosed is a driver circuit including a latch circuit, a shift register circuit, and a switching circuit, where the latch circuit is provided over the shift register circuit and the switching circuit. The shift register circuit and the switching circuit may have a silicon-based semiconductor, while the latch circuit may have an oxide semiconductor. The latch circuit includes a first transistor and a second transistor connected in series. The latch circuit may further include a first capacitor and a second capacitor which are electrically connected to the first transistor and the second transistor. A display device using the driver circuit as well as a method for preparing the driver circuit is also disclosed.
