Adaptive dimming and adaptive boosting backlight technologies for LCD-TV systems
Design How-To 11/14/2007 Post a comment
LCD-TV systems need to render video and multi-media images with an optimal front-of-screen performance. They have to meet many requirements, like: contrast, brightness, color, flicker, motion portrayal, viewing angle, dissipation and cost. All these items are directly related to the backlight. In this paper we will show the benefits of adaptive dimming and adaptive boosting technologies, and extend the scope to 2D backlights
