摘要： A liquid crystal display (LCD) and a driving method thereof are disclosed. The LCD includes: an LCD panel, a grayscale voltage output portion and a grayscale voltage adjusting portion. The LCD panel includes a deformation area formed by bonding of a driver integrated circuit, and the deformation area includes a first subpixel. The grayscale voltage output portion is configured to output a first grayscale voltage to the first subpixel. The grayscale voltage adjusting portion is configured to adjust the first grayscale voltage into a second grayscale voltage, so that a brightness of the first subpixel at the second grayscale voltage is less than a brightness of the first subpixel at the first grayscale voltage.

摘要： A display device and a drive method, the display device including: an edge-lit backlight module; a liquid crystal display panel positioned on the light-emergent side of the edge-lit backlight module; and a polymer liquid crystal film positioned between the liquid crystal display panel and the edge-lit backlight module, and including a plurality of closely arranged independent dimming areas, each dimming area being configured for independent control of light transmittance. The present display device takes advantage of the characteristics of the polymer liquid crystal film, loading different driving voltages in different dimming areas and changing the transmittance of the polymer liquid crystal film.
