Filed: 1994-09-26
Abstract: PURPOSE: To make the size small and to make the weight light by providing an image illuminant, a lens with negative power to reduce an image light in a horizontal direction, a rotary scanning prism, and a lens with positive power to magnify the image light. CONSTITUTION: The display device is made up of R, G, B image illuminants 1a, 1b, 1c, a negative power lens 2, a rotary scanning prism 3, and a positive power lens 4. Let the length of an image light in the horizontal direction be L, a required maximum vertical displacement (h) is obtained by a specific equation based on the condition of aspect ratio of 4:3. For example, in the case of magnification of the negative power lens 2 to be 0.5, only a field angle in the horizontal direction is compressed and the field angle in the vertical direction depends on a length of a side of the prism, the displacement (h) is enough to be half (h=0.188L). Then length of a side (d) of the prism is d=0.57L and also it indicates a half. Furthermore, the volume is decreased to 1/4 and a load exerted to a motor is much reduced.  Furthermore, a space required for rotation of the prism is reduced and it much contributes to miniaturization.
