Patent ID: 8743153

Claim:
A display device for a vehicle comprising: a liquid crystal panel displaying an image; a light source illuminating the liquid crystal panel by light emission; and a controller controlling the liquid crystal panel and the light source, wherein the liquid crystal panel includes: a particular display pixel for displaying a particular image at a particular time; and a normal display pixel displaying a normal image at a normal time when the particular image is not displayed by the particular display pixel and at the particular time, wherein the controller controls a ratio of a gradation value of the normal display pixel to a set gradation value of the normal display pixel as a gradation ratio of the normal display pixel, and further controls a ratio of a gradation value of the particular display pixel to a set gradation value of the particular display pixel as a gradation ratio of the particular display pixel, wherein the controller sets first and second modes as control modes, the first mode in which the light source emits light, and the second mode in which the light source emits light with brightness lower than in the first mode, wherein, in the first mode, the controller sets the gradation ratio of the normal display pixel to maximum, and further sets the gradation ratio of the particular display pixel at the particular time to maximum, wherein, in the first mode, the liquid crystal panel displays both of the normal image and the particular image at the particular time, and the liquid crystal panel displays only the normal image at the normal time, wherein, in the second mode, the controller executes a gradation processing to make the gradation ratio of the particular display pixel at the particular time larger than the gradation ratio of the normal display pixel, and wherein, in the second mode, the liquid crystal panel displays both of the normal image and the particular image at the particular time, and the liquid crystal panel displays only the normal image at the normal time.
