The embodiment of the invention provides a projection device, display equipment and a vehicle, relates to the technical field of light display, and mainly aims to provide a three-dimensional projection device which does not lose image resolution and is high in imaging quality. Comprising but not limited to specific scenes such as near-to-eye display, head-up display, projection display equipment and vehicle-mounted display equipment. The projection device comprises a display module and a light splitting unit, the display module is used for generating a first light beam and emitting the first light beam; the first light beam comprises first polarized light carrying left eye image information and second polarized light carrying right eye image information, and the polarization direction of the second polarized light is perpendicular to that of the first polarized light. The light splitting unit is located on the light emitting side of the display module, namely on the propagation path of the first light beam, and is used for enabling the first polarized light and/or the second polarized light in the first light beam to be emitted in different directions by enabling the first light beam to generate birefringence.
本申请实施例提供了投影装置、显示设备及交通工具,涉及光显示技术领域,主要目的在于提供一种不损失图像分辨率的高成像质量的三维立体投影装置,包括但不限于应用在如近眼显示、抬头显示、投影显示设备和车载显示设备等具体场景中。该投影装置包括:显示模组和分光单元;显示模组,用于生成第一光束,以及,射出第一光束;第一光束包括携带左眼图像信息的第一偏振光,和,携带右眼图像信息且偏振方向与第一偏振光垂直的第二偏振光。分光单元位于显示模组的出光侧,即位于第一光束的传播路径上,用于通过使得第一光束发生双折射,使得第一光束中的第一偏振光和/或第二偏振光以不同的方向射出。
