Patent ID: 8619104

Claim:
A liquid crystal display device comprising: a driver circuit configured to control a display portion; and a timing controller configured to control the driver circuit, wherein the timing controller is configured to be supplied with an image signal for displaying a still image, wherein the timing controller is configured to supply a start pulse, a clock signal, and a potential to the driver circuit, wherein the potential is selected from a first potential and a second potential which is smaller than the first potential, wherein the timing controller is configured to stop the clock signal after the start pulse stops and to change the potential from the first potential to the second potential after the clock signal stops, wherein the timing controller is configured to start supplying the clock signal after the potential is changed from the second potential to the first potential and to start supplying the start pulse after the supply of the clock signal is started, and wherein the timing controller is configured to determine a refresh rate to display an image corresponding to a total number of gray levels in the image signal on the display portion.
