Patent ID: 8002455

Claim:
A light-emitting panel comprising: a first light source for emitting first light of a first single color; a second light source for emitting second light of a second single color; a light guide plate comprising a light incident surface for receiving the first and second light, a display surface for total internal reflection of the first and second light, thereby blocking the first and second light from exiting through the display surface; a plurality of first microstructures formed at the display surface, the first microstructures being configured for destroying the total internal reflection of the first and second light at the display surface, thereby allowing the first and second light to exit through the display surface, the first microstructures being arranged to form a first pattern; a first dye material applied to the first microstructures for blocking the second light from passing through the first dye material and allowing the first light to pass through the first dye material; a plurality of second microstructures formed at the display surface, the second microstructures being configured for destroying the total internal reflection of the first and second light at the display surface, thereby allowing the first and second light to exit through the display surface, the second microstructures being arranged to form a second pattern; and a second dye material applied to the second microstructures for blocking the first light from passing through the second dye material and allowing the second light to pass through the second dye material.
