摘要
传统的液晶显示器(Liquid Crystal Display,LCD)如果要调整动态对比度,通常要通过增加背光源的发光二极管(Light Emitting Diode,LED)灯珠数量来实现.此种方法由于需要分多个区域控制LED背光,所以其电源时序控制电路非常复杂,系统的整体成本也会很高.对此,提出一种基于高清图像系统的低成本高动态对比度调整方法,介绍高清图像系统的设计框图和动态对比度的调整流程.该方案无须改变原有硬件系统,整体造价较低,在对成本受限的场景中展现出广阔的应用前景.
Abstract
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.
