| 20100178613 | DISPLAY DEVICE UNIFORMING LIGHT DISTRIBUTION THROUGHOUT AREAS AND METHOD FOR MANUFACTURING SAME - Disclosed are an optical display device producing uniform light distribution and a method of fabricating such devices. The optical display device has waveguides arranged in vertical and horizontal directions. The waveguide has a conical shape whose cross-section decreases towards the light-projection side thereof. At least one of the size, height, spacing, and refraction index of the waveguide is designed to be different for each section, depending on an incident angle and/or intensity of light inputted from a light source. Therefore, the intensity of projected light can be made uniform over all sections of the optical device. | 07-15-2010 |
