The embodiment of the invention provides head-up display glass, a head-up display system and a vehicle, the head-up display system comprises projection equipment and head-up display glass, and the head-up display glass comprises a light-transmitting area and a circumferential shielding area surrounding and connected with the light-transmitting area. The head-up display glass further comprises a glass body, a shielding layer and a function display layer with a diffraction grating, the shielding layer and the function display layer are stacked on the glass body, a part of the function display layer and the shielding layer are stacked, the shielding layer is completely located in the shielding area, and the function display layer comprises a first diffraction layer and a second diffraction layer. The first diffraction layer is located in the shielding area, the second diffraction layer is located in the light-transmitting area, and the focal length of the first diffraction layer is smaller than that of the second diffraction layer. The head-up display system comprises the head-up display glass and the projection equipment, projection light emitted by the projection equipment diffracts image information through the first diffraction layer and then emits the image information out of the glass body to form a first image, and the image information is diffracted through the second diffraction layer and then emits the image information out of the glass body to form a second image.

    本申请实施例提供一种抬头显示玻璃、抬头显示系统及车辆,抬头显示系统包括投影设备及抬头显示玻璃,抬头显示玻璃包括透光区和环绕并连接透光区的周向的遮蔽区,抬头显示玻璃还包括玻璃本体、遮蔽层和具有衍射光栅的功能显示层,遮蔽层和功能显示层均层叠于玻璃本体,且部分功能显示层与遮蔽层叠设,遮蔽层完全位于遮蔽区内,功能显示层包括第一衍射层和第二衍射层,第一衍射层位于遮蔽区内,第二衍射层位于透光区内,第一衍射层的焦距小于第二衍射层的焦距。抬头显示系统包括抬头显示玻璃和投影设备,投影设备发出的投影光线将图像信息经第一衍射层衍射后射出玻璃本体形成第一图像,并将图像信息经第二衍射层衍射后射出玻璃本体形成第二图像。
