Problems solved by technology

Due to the large number of grid scanning lines of the display panel, the number of GOA units in the GOA circuit is relatively large. If all the GOA units reset the potential of the first node once after each frame, the function of the reset signal Reset The consumption is large, which will increase the logic power consumption of the display panel using the GOA circuit

Abstract

The invention provides a GOA circuit driving system and method, and a display device. When a level conversion module is detected to output a conversion driving signal to the GOA circuit by the GOA circuit driving system through a reset controller, the output current is correspondingly outputted to the GOA circuit, when the output current is greater than the preset value, a sequential controller iscontrolled by the reset controller for transmitting an initial reset signal having multiple high-potential pulses to the level conversion module, the initial reset signal is converted by the level conversion module and is then outputted to the GOA circuit, otherwise, the sequential controller is controlled by the reset controller for transmitting the low-potential initial reset signal to the level conversion module, the low-potential initial reset signal is converted by the level conversion module and is then outputted to the GOA circuit, and logic consumption of the GOA circuit for driving is reduced on the condition that operation of the GOA circuit is not influenced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a GOA circuit driving system, a GOA circuit driving method and a display device. Background technique [0002] A Liquid Crystal Display (LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc., occupy a dominant position in the field of flat panel display. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter substrate (ColorFilter, CF), and apply a driving volta...
