摘要： The optical system of a projection display apparatus. The projection display apparatus includes a light source, a prism, a light valve, and a projection lens. A light beam emitted from the light source impinges into the prism and passes through the first surface of the prism directly to illuminate the light valve which is placed near the first surface and parallels the first surface. By the reflection of the light valve, the light beam impinges into the first surface again, and illuminates a total internal reflection surface with an incidental angle large than the critical total reflection angle, so as to reflect the light beam out of the second surface of the prism and impinge to projection lens to form an image. Therefore, the optical system can increase the transmission and decrease the number of components, and reduce its overall volume.

摘要： A projection display system comprises an illumination device, a prism assembly, a projection lens and a reflective light valve. The prism assembly has a first light incident surface, a first light emitting surface and a second light emitting surface. The first light emitting surface is an optical curved surface. An illumination beam is incident on the light valve after it enters the prism assembly from the first light incident surface. A modulated beam is generated after it is processed through the light valve. Finally, the modulated beam is projected into the projection lens through the prism assembly. Because a surface of the prism assembly is set to be an optical curved surface to replace a lens in the projection lens or the illumination device, a back focal length of the system is shortened and the projection lens or the illumination device is simplified.
