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： An optical projection apparatus includes an illumination system, a projection lens unit, a reflective light valve, a first beam breaker and a second beam breaker. A light beam is provided by the illumination system. The projection lens unit and the reflective light valve are disposed on the transmission path of the light beam, and the reflective light valve is disposed between the illumination system and the projection lens unit. The first beam breaker and the second beam breaker are used to cut into the transmission path of the light beam from different directions to block a part of the light beam, and part of the light beam passes through the first beam breaker and the second beam breaker. The darker image projected by the optical projection apparatus has higher contrast and better uniformity.

摘要： An optical system disposes a total reflection lens between a light valve and a projection lens. When a white light beam, emitting from a light source, passes through a color-generating device, the color of the light beam is sequentially converted into red, green, and blue primaries, and uniformed by an integrator. Then, the light beam impinges into the total reflection lens and is reflected to the light valve. The light valve reflects the light beam into a projection lens to be projected on a screen. Therefore, this invention increases the projection efficiency, and reduces the bulk and components of the optical system.

The first color separating element transmits the first color light beams and reflects second color light beams emitted from at least a third light source and a fourth light source. The third light source and the fourth light source are differently positioned in the space. The first color separating element has a coating curved surface, and a curvature of the coating curved surface is varied according to positions of the third light source and the fourth light source to guide the second color light beams to propagate in the first direction.
