Abstract
A liquid crystal display and an electronic device are disclosed. The control unit applies voltages to sub-electrodes and a first transparent electrode according to image data to generate electric fields, so that liquid crystal molecules in regions of the liquid crystal layer corresponding to electrode units are deflected to form micro-prism structures, and the control unit controls the micro-prism structures by controlling magnitude of voltages on the sub-electrodes in the electrode units, thereby controlling an energy distribution ratio of emergent light resulted from refraction of the backlight′ light by the micro-prism structures and in a preset viewing angle range. Accordingly, luminance of light entering into the preset viewing angle range can be realized through controlling the micro-prism structures, thereby realizing gray scale display.
