Research on Low Cost and High Dynamic Contrast Adjustment Method Based on High Definition Image System
Traditional Liquid Crystal Display(LCD)if you want to adjust the dynamic contrast,usually by increasing the number of Light Emitting Diode(LED)lamp beads to achieve.This method needs to control the LED backlight in multiple areas,so its power timing control circuit is very complex,and the overall cost of the system will be high.This paper describes a low cost and high dynamic contrast adjustment method based on high definition image system,and introduces the design block diagram and dynamic contrast adjustment flow of high definition image system.This method does not need to change the original hardware system,the overall cost is low,and has a broad application prospect in the case of cost limitation.
