摘要： A light source device including a light emitting element emits a luminous flux, which is converged by a reflecting mirror. A conical light-refracting element receives the luminous flux converged by the reflecting mirror and changes the cone angle of the luminous flux. The luminous flux exiting the conical light-refracting element is diffused by a holographic diffuser and is then converged by at least one lens. The reflecting mirror may have an elliptic curvature or a parabolic curvature. The light source device is also used to form a projector for a projection type display apparatus. In the projector, the luminous flux emitted from the light source device may be separated by color separators into a plurality of colors of light. Then, each color of light is directed to the corresponding one of a plurality of light valves. Then, a color synthesizer synthesizes the colors of light emitted from the light valves into a composite image which in turn is projected onto a screen. A plurality of such projectors are used to construct a multiscreen projection type display system where each of the projectors projects a corresponding image. At least one reflecting mirror for bending a corresponding one of the images is included in the multiscreen projection type display system. The reflecting mirror projects the image onto a screen so that the images emitted from the plurality of projectors are combined into a composite image on the screen.

摘要： The present invention provides a color projector utilizing three liquid crystal display elements. The natural light is separated into illuminating rays of red, green and blue colors by a dichroic mirror, each of these illuminating rays being used to illuminate the corresponding one of the liquid crystal display elements. Each of the liquid crystal display elements is controlled by a desired image signal with respect to its transmittance at each pixel. After passed through the liquid crystal display elements, three kinds of colored illuminating rays are again synthesized by the other dichroic mirror to form a light beam which in turn is enlarged and projected by a projecting lens on a screen. By providing light source means including means for converting the natural light into the linearly polarized beam, the illuminating rays may have their polarizing angles coincide with each other without any loss of light. As the linearly polarized beam is reflected by the mirror system, the illuminating rays of red, green and blue colors are changed with respect to their polarizing angels. Depending on the changed polarizing angles, the polarizing angle of the light rays incident on each of the liquid crystal display elements may be adjusted to remove any loss of light.

摘要翻译： 本发明提供一种利用三个液晶显示元件的彩色投影仪。 通过二向色镜将自然光分离为红色，绿色和蓝色的照射光，这些照射光用于照射相应的一个液晶显示元件。 每个液晶显示元件通过相对于其在每个像素处的透射率的期望的图像信号来控制。 在通过液晶显示元件之后，再次通过另一个分色镜合成三种彩色照明光线，以形成光束，该光束又由投影透镜放大并投影在屏幕上。 通过提供包括用于将自然光转换成线偏振光束的装置的光源装置，照射光线可以使它们的偏振角度彼此一致而没有任何光损失。 当线偏振光束被反射镜系统反射时，红色，绿色和蓝色的照明光线相对于其极化天使而改变。 根据变化的偏振角，可以调整入射到每个液晶显示元件上的光线的偏振角，以消除任何光的损失。
