Liquid crystal display and shift register thereof
The present invention provides a liquid crystal display and a shift register thereof. Each shift register unit of the shift register comprises a storage circuit, receiving and temporarily storing a former stage signal, a voltage level control circuit and an inverter circuit, charging and discharging scan lines of a liquid crystal display panel, and a first node exists between the voltage level control circuit and the inverter circuit, and a second node exists between the storage circuit and the voltage level control circuit, and the storage circuit is employed to selectively invert and output received level signals to the second node under control of a first sequence signal, and the voltage level control circuit is employed to provide a low level signal to the first node, and the inverter circuit is employed to selectively invert and output the low level signal provided by the voltage level control circuit under control of a second sequence signal. With the aforementioned arrangement, the present is beneficial to the narrow frame or non frame design of the liquid crystal display panel and promote the process yield.
