Patent ID: 7068252

Claim:
A display unit having the horizontal direction for displaying a plurality of images including a first image and a second image, the display unit comprising: a light source having a plurality of light-emitting regions; a transmissive image display panel for displaying an image when light from the light source is transmitted therethrough, the transmissive image display panel including a predetermined number of pixels in the horizontal direction, and being arranged spaced apart from and facing the light source so that light from each light-emitting region illuminates at least two pixels; a light-emission control section for controlling the light source, the light-emission control section emitting at least one first selected light-emitting region among the plurality of light-emitting regions and non-emitting at least one second selected light-emitting region among the light-emitting regions adjacent to the at least one first selected light-emitting region, the light-emission control section alternately switching emitting and non-emitting of the at least one first selected light-emitting region and the at least one second selected light-emitting region at a predetermined cycle; and an image signal output section connected to the display panel for providing data of the plurality of images to the plurality of pixels, wherein the image signal output section provides first image data for displaying the first image to at least one first pixel of the plurality of pixels, and provides second image data for displaying the second image to at least one second pixel of the plurality of pixels adjacent to the at least one first pixel, and wherein in synchronization with the switching of the emitting and non-emitting of each light-emitting region by the light-emission control section, the image signal output section alternately provides data of an image different from the image, displayed before switching of the emitting and non-emitting of the light-emitting region, to the at least one first pixel and the at least one second pixel, wherein in the horizontal direction of the transmissive image display panel, the light-emitting regions are arranged at the substantially same pitch as that of the pixels, and the light-emitting regions each have substantially the same width as that of each pixel, and wherein the number of the plurality of light-emitting regions in the horizontal direction is greater than that of the pixels.
