Abstract:
A projection screen of a head-up display has a projection surface and a back surface opposite to the projection surface. The projection surface is used for receiving an image beam projected by an image projection component and reflecting part of the image beam. The projection screen includes a photochromic layer disposed on the transmission path of the image beam. When an ambient light irradiates the back surface of the projection screen, the transmittance of the photochromic layer decreases as the intensity of the ambient light increases.

Claim (Index 1):
A projection screen of a head-up display, the projection screen having a projection surface and a back surface opposite to the projection surface, wherein an image projection component projects an image beam on the projection surface, and the projection surface reflects part of the image beam, the projection screen comprising:\n a photochromic layer, disposed on the transmission path of the image beam, wherein a transmittance of the photochromic layer decreases as the intensity of an ambient light increases when the ambient light irradiates the back surface of the projection screen.
