Abstract
A viewing-angle adjustable liquid crystal display includes a display panel and a data driver. The display panel includes several pixel units. Each pixel unit has a first sub-pixel and a second sub-pixel. The data driver provides a first driving voltage and a second driving voltage, respectively, to the first sub-pixel and the second sub-pixel. When the liquid crystal display is operated in the wide viewing-angle mode, the first and the second driving voltage of each pixel unit are substantially equal to a pixel voltage, while when the liquid crystal display is operated in the narrow viewing-angle mode, the first driving voltages corresponding to one portion of the pixel units and the second driving voltages corresponding to the other portion of the pixel units are substantially equal to a gray-level voltage.
