Head-up display, vehicle and controlling method of head-up display
First Claim
1. A head-up display adapted to a vehicle, the vehicle having a windshield, the head-up display comprising:
- a casing;
a control circuit board disposed in the casing;
a display panel disposed in the casing and coupled to the control circuit board, wherein the display panel is aligned to a displaying region of the head-up display; and
a plate, disposed in the casing and covering the display panel, wherein when the vehicle is started, the control circuit board receives power, and the transmittance of the plate is increased so that an image displayed on the display panel is directly projected to the windshield through the plate, and when the vehicle is not activated, the control circuit board does not receive power, and the transmittance of the plate is decreased such that an external light via the windshield irradiating on the display panel through the plate is reduced,wherein the display panel has a display surface facing the plate, the plate has a rear surface facing the display panel, and an area of the display surface is not smaller than an area of the rear surface.

Abstract
A head-up display including a casing, a control circuit board, a display panel, and a plate is provided. The control circuit board is disposed in the casing. The display panel is disposed in the casing and electrically connected to the control circuit board. The plate is fixed to the casing and covers the display panel. The transmittance of the plate is capable of being changed, so that an image displayed on the display panel is projected out through the plate, or external light is stopped from illuminating the display panel through the plate. A vehicle having the head-up display and a controlling method of the head-up display are provided as well.

17. A controlling method for a head-up display adapted to a vehicle, the vehicle having a windshield, the head-up display comprising a display panel, a plate covering the display panel, and a control circuit board, the controlling method comprising:
-
sensing temperature or brightness of an environment; and changing transmittance of the plate, wherein when the vehicle is started, the control circuit board receives power, and the transmittance of the plate is increased according to the temperature or the brightness of the environment so that an image displayed on the display panel is directly projected to the windshield through the plate, and when the vehicle is not activated, the control circuit board does not receive power, and the transmittance of the plate is decreased such that an external light via the windshield irradiating on the display panel through the plate is reduced, wherein the display panel is aligned to a displaying region of the head-up display, wherein the display panel has a display surface facing the plate, the plate has a rear surface facing the display panel, and an area of the display surface is not smaller than an area of the rear surface. - View Dependent Claims (18, 19, 20, 21)
