Abstract

The invention provides a gray scale transition frame generation method. The gray scale transition frame generation method comprises the steps that the line display effective value or the column display effective value, the maximum gray scale value, the minimum gray scale value and the transition display order number of a display panel are acquired; the line display effective value number of pixel points or the column display effective value number of pixel points of the display panel are evenly divided into the transition display order number of continuous blocks; the transition display order number of gray scale values are selected in turn from the minimum gray scale value to the maximum gray scale value; and the selected gray scale values are respectively filled in the pixel values of the transition display order number of continuous blocks in turn so that a gray scale transition frame is generated. The invention also provides a gray scale transition frame generation device. According to the gray scale transition frame generation method and device, the transition frame of any gray scale can be outputted and thickness of transition stripes is relatively uniform.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panels, in particular to a method and device for generating a gray scale transition picture. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as light and thin, energy-saving, non-radiation, etc., so it has gradually replaced the traditional cathode ray tube (CRT) display. Currently, liquid crystal displays are widely used in high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, mobile phones, digital cameras and other electronic devices. [0003] Taking a thin film transistor (ThinFilmTransistor, TFT) liquid crystal display device as an example, it includes: a liquid crystal display panel and a driving circuit, wherein the liquid crystal display panel includes a plurality of gate lines and a plurality of data lines, and two adjacent gate lines A pixel unit is formed by inte...
