    摘要: A compact, high resolution projection imaged display device using a reflective-type display element which uniformly illuminates the entirety of the display element without reducing illumination efficiency and ensures viewing conditions of excellent and uniform brightness extending to the fringe of the field of view is provided by an illumination optical system for redirecting illumination light from an illumination light source onto a reflective-type display element. The reflective-type display element reflects light into the viewing optical system wherein the illumination optical system is constructed so as to have an approximate conjugate relationship between the pupil of the user and the illumination light from the illumination light source.

    摘要: A projection optical system projects an enlarged image of a light valve image onto a screen. The system has, from the conjugate enlargement side: a negative front lens unit, optical path turning means (including a reflecting surface), a positive rear lens unit, and projection light preparing means, which can separate illumination and projection light, or can integrate light of different colors, or can do both. Each of the front and rear lens units includes at least one aspherical surface. The front lens unit has a negative first lens element at its conjugate-enlargement end and a negative second lens element at the conjugate reduction side of the first lens element. The rear lens unit includes a positive third lens element made of an anomalous dispersion material. The center of the light valve is not located on the optical axis of the rear lens unit.

    摘要: A projecting image display device is disclosed which includes a display and a micro lens array, where the pixels of the display and the micro lens elements each have non symmetric properties in length and width directions. The micro lens concentrates color-separated light onto pixels of a display device so that light does not hit the black matrix. By providing a display having pixels which are not equal in length and width, pixels corresponding to red (R), green (G) and blue (B) can be arranged in a substantially square area, and by providing a micro lens array which has non symmetric properties in length and width, the color separated light can be concentrated onto the non square display pixels.
