Abstract

The invention discloses a driving circuit, a four-stage driving circuit and a display panel. The driving circuit comprises an input module, a first output module, a second output module and a pull-down module. The control end of the first output module and the control end of the second output module are connected with the output end of the input module and receive control signals output by the input module respectively, and the output end of the first output module and the output end of the second output module are connected with the pull-down module and receive pull-down signals respectively. Therefore, a one-stage driving circuit outputs a two-stage driving signal, and compared with an existing framework in which a two-stage driving circuit is needed to output a two-stage driving signal, one group of input module and pull-down modules is reduced. The invention further discloses a four-stage driving circuit and a display panel. The number of components used is reduced, the frame of a display product is further reduced, the cost is saved, and meanwhile, the competitiveness of the product is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving circuit, a four-level driving circuit and a display panel. Background technique [0002] Liquid crystal displays have been widely used because of their thin body, power saving, no radiation and many other advantages. [0003] With the improvement of living standards, people also put forward higher requirements for display products, such as lower prices and narrower borders. [0004] At present, in order to reduce product costs, GDL (Gate Driver less, less gate drive) circuit drive technology is usually used in the manufacturing process, so that there is no need to use chip drivers on both sides of the thin-film transistor liquid crystal display panel, which greatly reduces product costs. However, due to the large number of thin-film transistors used, the frame of the display product is relatively wide, which does not meet consumers' pursuit of display products with a ...
