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 9):
The projection screen according to  claim 1 , wherein the photochromic layer comprises a color-changing material, and the color-changing material is selected from the group consisting of silver bromide, silver chloride, silver iodide and organic photochromic molecules.
