プデイスプレイ装置。[Scope of Claim for Utility Model Registration] In a head-up display device that projects speed information onto a combiner that forms a reflective section provided inside the windshield of an automobile, an EC located near the combiner.
a control unit having a coloring driving relay and a decoloring driving relay connected to the EC cell connected to the output side, and a vehicle speed sensor and a sunlight sensor connected to the input side, The EC section is configured to correct the background brightness by comparing the amount of incident light with respect to a predetermined background brightness based on the signal from the incident sensor when the vehicle is running according to the input signal from the vehicle speed sensor. A head-up display device characterized in that the brightness of the EC cell is controlled by outputting a driving voltage to the cell.
