摘要: | Color breakup is a lethal issue to conventional field-sequential-color LCDs. Several methods have been proposed to solve this problem. However, these solutions are either more than 180 Hz-the currently used LC mode is not sufficiently fast for this field rate-or they degrade the image quality while using a field rate of 120 Hz. To overcome these limitations, a 120 Hz Stencil Local Primary Desaturation, Stencil-LPD, is presented in this work. The 120 Hz Stencil-LPD method provides reduced but sufficient saturated backlight color to precisely present an image with less color distortion or color breakup. After optimizing a number of backlight segments, the experimental results demonstrate that the image fidelity is significantly improved and color breakup is greatly suppressed compared to the existing methods. |
