Abstract:
A display apparatus for a vehicle includes a liquid crystal panel, a backlight unit, and a control circuit. The liquid crystal panel has a screen constructed with pixels. A first portion of the pixels displays a speed image indicating a vehicle speed. A second portion of the pixels displays a warning image indicating a vehicle abnormal condition. The control circuit adjusts brightness of the screen by controlling intensity of colors in the speed and warning images in such a manner that brightness of the warning image is greater than brightness of the speed image. The luminance of the light supplied to the screen by the backlight unit is kept constant.
