The embodiment of the invention provides head-up display glass, a head-up display system and a vehicle, which can improve the permeability of a function display area of the head-up display glass and improve the visibility of a driver and passengers to the outside of the vehicle. The head-up display glass comprises a glass substrate and a functional reflecting layer, wherein the functional reflecting layer is arranged on the inner surface of the glass substrate; the head-up display glass comprises a visual field area, a function display area and a shielding area, the function display area comprises at least one semitransparent display area located between the visual field area and the shielding area, and the total visible light transmittance of the semitransparent display area is smaller than or equal to the total visible light transmittance of the visual field area and larger than the total visible light transmittance of the shielding area. At least part of the semitransparent display area is covered by the functional reflecting layer, the part, covered by the functional reflecting layer, of the semitransparent display area has main image reflectivity RL1 and auxiliary image reflectivity RL2 for projection light, and the ratio RR12 of the main image reflectivity RL1 to the auxiliary image reflectivity RL2 is larger than or equal to 15.
本申请的实施例提供一种抬头显示玻璃、抬头显示系统与车辆,能够提高抬头显示玻璃的功能显示区的通透性,提升驾乘人员对车外的可视性。抬头显示玻璃包括玻璃基板和功能反射层,功能反射层设于玻璃基板的内表面;抬头显示玻璃包括视野区、功能显示区和遮蔽区,功能显示区包括至少一个位于视野区和遮蔽区之间的半透明显示区域,半透明显示区域的可见光总透射率小于或等于视野区的可见光总透射率且大于遮蔽区的可见光总透射率,半透明显示区域至少部分被功能反射层覆盖,半透明显示区域被功能反射层覆盖的部分对投影光线具有主像反射率RL1和副像反射率RL2,主像反射率RL1和副像反射率RL2的比值RR12≥15。
