Problems solved by technology

However, as the size of liquid crystal displays becomes larger and larger, the thin film transistors used for charging also become larger, and the load on the circuit also increases at this time, causing excessive accumulated charges in the circuit, which in turn leads to the operation of the drive circuit. delay, and misoperation of the overall drive circuit

Embodiment Construction

[0030] The invention proposes a driving circuit to solve the problem of excessive accumulated charge and stabilize the output driving signal so as to avoid the misoperation of the driving circuit.

[0031] The driving circuit is controlled by timing signals to drive multiple scanning lines of the liquid crystal display, wherein the driving circuit also includes a plurality of sequentially connected driving circuit units, and each driving circuit unit has the same structure. The timing signal is further divided into a positive timing signal CK and an inverted timing signal XCK, and the phases of the two signals are opposite to each other. Wherein, for any two adjacent driving circuit units, one of them receives the positive phase timing signal CK, and the other receives the negative phase timing signal XCK. According to an embodiment, if the driving circuit unit of the Nth stage receives the positive phase timing signal CK, the driving circuit units of the (N+1)th stage and (N−...

Description

technical field [0001] The present invention relates to a driving circuit, and in particular to a driving circuit related to a liquid crystal display device. Background technique [0002] In recent years, the technology industry has been developed, and various electronic products are changing with each passing day. Among them, due to the advantages of thinness, low power consumption, and compatibility with semiconductor process technology, liquid crystal displays have expanded to various application levels in a short period of time, and have even become the mainstream of flat-panel displays. In liquid crystal displays, the driving circuit is often one of the important key technologies. Therefore, how to improve the driving circuit has become an urgent problem to be solved. [0003] In the driving circuit of the recently developed liquid crystal display, the method is to make a driving circuit including a plurality of driving circuit units on a glass substrate, and use thes...
