Liquid crystal display device and fabricating method and driving method thereof

摘要

Disclosed is a liquid crystal display device, a fabricating method, and a driving method thereof that includes at least one integrated photosensor that senses external light illumination on the liquid crystal display device. A sensing signal from the at least one photosensors are converted into a digital signal that is stored to represent an external illumination distribution. The liquid crystal display device includes a backlight that has a plurality of light sources that may be independently driven. A controller generates a control signal that independently drives the light sources in a manner corresponding to the illumination distribution. In doing so, areas of the liquid crystal display device may be provided with a greater amount of light from a corresponding light source so that externally illuminated areas of the liquid crystal display device do not suffer from reduced contrast.
