Abstract
A novel image synchronized brightness control (ISBC) method for active matrix liquid crystal display (AMLCD) was developed, where automatic modulation of the backlight luminance is performed according to the gray distribution of image data. The ISBC can deliver a peak luminance of 500 ∼ 600 nits, which is very comparable to that of cathode ray tubes (CRTs) and is 2 to 3 times higher than that of normal LCD. The dynamic CR is over 700. With this ISBC method we can display a vivid moving image, while maintaining the same level of power consumption and a backlight.Keywords
