1. Field of the Invention
The invention relates in general to a shift register, and more particularly to a shift register whose shift register circuit of each stage has a control circuit which provides a control signal for compensating the shift register circuit of the previous stage.
2. Description of the Related Art
With the rapid advance in science and technology, liquid crystal display has been widely used in the display of electronic products such as TV, computer screen, notebook computer, mobile phone and personal digital assistant (PDA). A liquid crystal display includes a source driver, a gate driver and a liquid crystal display (LCD) panel, wherein the LCD panel has a pixel array, the gate driver sequentially turns on the corresponding pixel row of the pixel array for outputting the pixel data to the pixel, so as to display the image.
The current technology normally implements the gate driver, which sequentially turns on the corresponding pixel row of the pixel array, by the shift register. The gate driver has much to do with the display quality of the liquid crystal display. Therefore, how to design a shift register whose output signal has slight distortion for improving the efficiency of the gate driver and the display quality of the liquid crystal display has become a focus to the display industry.
