Adaptive Refresh Frequency Switching Method

Abstract

The invention relates to an adaptive refresh rate switching method, and the method comprises the steps providing an adaptive refresh rate switching system for guaranteeing that the real-time refresh rate of a television set is adapted to the monotonous degree of a currently displayed content. The system comprises gun-type shooting equipment which is disposed on a wall opposite to the television set, and is used for carrying out the instant image data collection of the current content on a display screen of the television set, so as to obtain and output a plurality of real-time screen images which are continuous in time; refresh rate changing equipment which is disposed on an integrated circuit of the television set, is connected with a display driver of the television set, and is used forreceiving the real-time refresh rate and changing the current refreshing rate of the display screen of the television set based on the received real-time refresh rate; and frequency analysis equipmentwhich is used for determining a corresponding real-time refresh rate based on the monotonous degree of the current content on the display screen of the television set.

Description

technical field [0001] The invention relates to the field of televisions, in particular to an adaptive refresh frequency switching method. Background technique [0002] Instantly transmit live visual images by means of electricity. Similar to movies, television uses the visual residual effect of the human eye to display frame-by-frame still images, forming visually moving images. The sending end of the TV system converts each tiny part of the scene into electrical signals according to brightness and chromaticity, and then transmits them sequentially. At the receiving end, the brightness and chromaticity of each tiny part are displayed according to the corresponding geometric position to reproduce the entire original image. [0003] As a device for receiving TV broadcasts, a TV is composed of complex electronic circuits, speakers, and fluorescent screens. Its function is to receive the full TV signal transmitted by the TV station through the antenna, and then separate the ...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides an adaptive refresh frequency switching method, which can ensure that the real-time refresh frequency of the TV adapts to the monotonous degree of the current display content, thereby avoiding that when the current display content of the TV is too complicated, the The real-time refresh rate of the TV still maintains a relatively simple value, resulting in a rough display interface, which effectively improves the intelligence level of the TV
