Abstract
A display apparatus for use in a vehicle has a liquid crystal display panel, and the panel includes a first pixel area for displaying a meter image that represents vehicle condition values, and a second pixel area for displaying an outside image that calls attention of occupants as a warning image. Further, an input unit of the apparatus receives inputs of adjustment value from occupants of the vehicle for adjusting brightness of the meter image and the outside image. A main control unit and a drawing unit of the apparatus cooperatively serve as a controller of the apparatus by changing gradation ratio of the first and second pixel areas so that the gradation ratio of the second pixel area becomes greater than the gradation ratio of the first pixel area according to the input of the adjustment value.
