Projection screen of head-up display |
| 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. |
