Abstract
Official abstract text for this publication.
To suppress deterioration of quality of a still image displayed with a reduced refresh rate. A liquid crystal display device includes a display portion that is controlled by a driver circuit and includes normally white mode (or normally black mode) liquid crystals, and a timing controller for controlling the driver circuit. The timing controller is supplied with an image signal for displaying a moving image and an image signal for displaying a still image. The absolute value of a voltage applied to the liquid crystals in order to express black (or white) in an image corresponding to the image signal for displaying the still image is larger than that of a voltage applied to the liquid crystals in order to express black (or white) in an image corresponding to the image signal for displaying the moving image.
First claim
Opening claim text (preview).
The invention claimed is: 1. A display device comprising: a display portion including a display element, and a driver circuit controlling the display portion, wherein the display device has a first period for displaying a moving image and a second period for displaying a still image, and wherein a difference between an absolute value of a lowest voltage among voltages applied to the display element to express black and an absolute value of a lowest voltage among voltages app…
