Abstract

The invention discloses a driving circuit of a display panel and the display panel. The driving circuit comprises a time sequence control circuit, a power supply circuit, a grid driver, a voltage reduction circuit and a switch circuit, wherein the time sequence control circuit is used for reading initialization data of the display panel; the power supply circuit is used for supplying power to thedisplay panel; the grid driver is used for driving scanning lines of the panel; the voltage reduction circuit is used for conducting voltage reduction on input signals; a first input end of the switchsignal is connected with the time sequence control circuit, the power supply circuit is connected with a second input end of the switch circuit through the voltage reduction circuit, and the output end of the switch circuit is connected with the grid driver. Through output of the grid driver, abnormal startup pictures are avoided, the design is simple and easy to implement, the cost is low, and the startup time is shortened.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving circuit of a display panel and a display panel. Background technique [0002] With the continuous development of liquid crystal technology, liquid crystal displays have been widely used in fields such as computers, mobile phones, and televisions. Since the liquid crystal display panel itself does not have luminescence, it is necessary to add a backlight module to the panel. The backlight module is one of the key components of the liquid crystal display. It is used to supply sufficient brightness and uniformly distributed light sources to enable normal display. image. The luminous effect of the backlight module will directly affect the visual effect of the liquid crystal display. When the display device is turned on, each unit needs initial configuration, and the display panel of the display device can display normally only after each unit completes the initia...
