<P>PROBLEM TO BE SOLVED: To provide a three-dimensional display having further improved visibility and easy controlling properties in a three-dimensional display using a back light whose light direction is controlled by time-sharing. <P>SOLUTION: The three-dimensional display is composed of a main part and additional elements provided in the main part. The main part has a stripe light source 3 in which first and second light emitting parts 31, 32 (the first and second emitting parts correspond to the left and right eyes, respectively, ) are alternately arranged in stripes; lenticular lenses 4 to direct the light emitted from the first and second light emitting parts to a first and second directions, respectively; a transmission type LCD 5 the back face of which is illuminated with the light emitted from the lenses; and a three-dimensional display controller 6 which alternately turns on the first and second light emitting parts at an invisible rate to alternately display, on the transmission LCD, first and second parallax images synchronized with the above blinks and corresponding to the first and second directions. The additional elements are an antireflection film 7 to prevent reflection on the image display screen; a blink mode switch 8 to act on the three-dimensional display controller to simultaneously and continuously turn on the first and second light emitting parts; and/or a stripe pitch controller 9 to move the boundary between the first and second light emitting parts. <P>COPYRIGHT: (C)2004,JPO |
