Driving method of liquid crystal display

Abstract

The invention provides a driving method of a liquid crystal display, and the liquid crystal display includes a liquid crystal panel component, a plurality of scanning lines and data lines which are limited in a cross mode, a source electrode actuator, a grid electrode actuator and a time schedule controller. An image processor is arranged inside the time schedule controller, the image processor outputs a normal picture frame in a cross mode and produces a black picture frame, and scanning frequencies of the normal picture frame and the adjacent black picture frame are different. When pictures of the display are output, the adjacent two pictures utilize different picture frame scanning frequencies; due to the fact that the picture frame scanning frequencies directly affect the charging time of pixels, the faster the picture frame scanning frequency is, the shorter the charging time is. By increasing the black picture frame scanning frequency and decreasing the normal picture frame scanning frequency, the driving method of the liquid crystal display can greatly increase the charging time of the pixels of the normal picture frame. Frequency doubling is carried out over clock signals which are input from the exterior and are provided for an internal circuit to carry out a picture frame scanning frequency modulation, so that the purpose of regulating a duty ratio between the two adjacent pictures is achieved.

Description

technical field [0001] The invention relates to a driving method of a liquid crystal display, in particular to a driving method of a black insertion driving circuit. Background technique [0002] The black insertion technology is currently mainly used to solve the image smear of the continuous display. The traditional cathode ray tube display adopts the pulse display mode, and the phosphor powder is hit by the electron beam to emit light. The residual time of the glow is extremely short, and the response time is only 1~3 Milliseconds, continuous displays such as liquid crystal displays use liquid crystal molecules to control the on and off of light, and continuously output light in one frame. Due to the impact of the persistence of human vision, this kind of continuous display will cause image seriousness when switching screens. Smear, so this smear phenomenon can be improved by black insertion technology. [0003] The black insertion technology inserts a black screen betwe...
