Patent ID: 8297758

Claim:
A multimedia player capable of displaying two projection images, the multimedia player comprising: a first projection unit displaying a first projection image; and a second projection unit displaying a second projection image, wherein the first projection unit comprises: a first driving unit controlling an operation of the first projection unit and providing an image signal of the first projection image to be displayed; a first light source unit; a first light modulation device outputting the first projection image by modulating light provided from the light source in response to the image signal of the first projection image; and a first projection lens unit magnifying and projecting an image that is output from the first light modulation device, and wherein the second projection unit comprises: a second driving unit by controlling an operation of the second projection unit and providing an image signal of the second projection image to be displayed; a second light source unit; a second light modulation device outputting the second projection image by modulating light provided from the light source unit in response to the image signal of the second projection image; and a second projection lens unit magnifying and projecting an image that is output from the second light modulation device, wherein focal lengths of the first and second projection lens units are initially set so that an image is projected at a predetermined position extended from a bottom plane over which the multimedia player is located, wherein the first light source unit and the second light source unit are constructed with LED arrays constructed with red (R), blue (B), and green (G) LEDs, and the LED arrays are sequentially driven according to a predetermined frequency to sequentially provide light beams with R, G and B colors, the multimedia player further comprising a screen sensing unit sensing a color of an area in which an image is to be displayed, wherein the first and second driving units detect a complementary color of the sensed color of the bottom plane by using the screen sensing unit and increase brightness of alight source corresponding to the complementary color among light sources of the first and second light source units.
