Abstract:
1. A liquid crystal display device comprising: a plurality of pixels provided in matrix, each of which comprises a liquid crystal element; a gate driver for supplying gate signals to the plurality of pixels; a source driver for supplying any one of analog video signals and digital video signals to the plurality of pixels; an optical sensor; a display mode-specific video signal generation circuit operationally connected to the optical sensor, the display mode-specific video signal generation circuit comprising a first switch, a second switch, a third switch, and a level conversion circuit, and a first line to a n-th line each electrically connected to the display mode-specific video signal generation circuit, wherein n is a natural number, wherein the second switch and the third switch are each electrically connected to the level conversion circuit, wherein the second switch is electrically connected to the n-th line, wherein the first switch is capable of turning on so that the display mode-specific video signal generation circuit supplies the analog video signals to the source driver in a first display mode, wherein the second switch and the third switch are capable of turning on so that the display mode-specific video signal generation circuit supplies the digital video signals to the source driver in a second display mode, and wherein the first display mode and the second display mode are switched according to an external light intensity.
