Abstract:
1. A display apparatus for use in a vehicle comprising: a liquid crystal panel capable of displaying an image in a vehicle, wherein the liquid crystal panel includes a meter display pixel that displays a meter image to represent a vehicle condition value and a warning display pixel that displays a warning image; an illumination unit capable of lighting the liquid crystal panel by emitting light; an input unit capable of accepting an input from an occupant of the vehicle, wherein the input unit receives the input of an adjustment value for controlling brightness of the image including the meter image and the warning image; and a control unit capable of controlling the liquid crystal panel and the illumination unit, wherein the control unit changes both of a meter display gradation ratio and a warning display gradation ratio according to the adjustment value so that the warning display gradation value is greater than the meter display gradation value when the meter display gradation ratio is defined as a ratio of the gradation value of the meter display pixel to a predetermined gradation value and the warning display gradation ratio is defined as a ratio of the gradation value of the warning display pixel to a predetermined gradation value, and wherein, when the meter image and the warning image are displayed simultaneously, the meter display gradation ratio and the warning display gradation ratio are changed to satisfy a relationship that the warning display gradation value is greater than the meter display gradation value according to the adjustment value and are changed from a single maximum ratio or are changed from two different ratios so that the warning display gradation ratio is changed from a ratio greater than the meter display gradation ratio.
