Abstract
A retina direct display device provides an observer with the display of a plane image or a stereoscopic image. The retina direct display device is, for example, incorporated with an acoustic device to constitute a television receiver. The retina direct display device comprises a visible light conversion means, a retina projection means and an eye movement tracking means. The visible light conversion means converts an input video signal to a beam of visible light. The retina projection means deflects the beam horizontally and vertically so that retinas are raster scanned through pupils of both eyes by the deflected beam. The eye movement tracking means detects the movement direction of the pupils and permits the direction of the beam emitted from the retina projection means to track the movement of the pupils based on the result of the detection. Accordingly, the device enables the video display of high resolution without deteriorating picture quality of the input video signal of high quality and also enables the reduction of the size and manufacturing cost of the device.
