Abstract
Provided is an image display device including: an image signal controller generating a driving signal and an image data signal; an image light beam supply unit generating image light beams using a signal applied by the image signal controller; and a light guide plate having a mapping plate reflecting the light beams that are incident from the image light beam supply unit and a display plate receiving the light beams reflected by the mapping plate to display an image.
Claims9
An image display device comprising:
- an image signal controller generating a driving signal and an image data signal;
- an image light beam supply unit including a plurality of light means arranged in a matrix configuration, the plurality of light means each corresponding to pixel unit and generating one of red, green and blue image light beams corresponding to image data signal under the control of the driving signal from the image signal controller;
- and
- a light guide plate having a mapping plate including a plurality of reflection grooves corresponding to the pixel unit each for reflecting the light beams that are incident from the image light beam supply unit and a display plate disposed on the mapping plate for displaying the light beams reflected by the mapping plate to display an image.
