Multimedia player displaying 2 projection images

A multimedia player providing two projection images which operates in a dual mode by concurrently providing first and second images by using a single light source unit, the multimedia player comprising:

• a driving unit controlling an entire operation and providing first and second image signals;
• a light source;
• a polarization beam splitter splitting light provided from the light source unit into first and second polarized light beams;
• a first light modulation device located in a path through which the first polarized light beam provided from the PBS (polarization beam splitter) proceeds, the first light modulation device modulating the first polarized light beam in response to a first image signal and providing the first image;
• a first projection lens unit magnifying and projecting the first image provided from the first light modulation device;
• a second light modulation device located in a path through which the second polarized light beam provided from the PBS proceeds, the second light modulation device modulating the second polarized light beam in response to a second image signal and providing the second image;
• and
• a second projection lens unit magnifying and projecting the second image provided from the second light modulation device,
• wherein images projected from the first and second projection lens units are formed at previously set first and second positions,
• 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, and
• wherein the light source is 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 comprising a screen sensing unit sensing a color of an area in which an image is to be displayed,
• wherein the driving unit detects a complementary color of the sensed color of the bottom plane by using the screen sensing unit and increases brightness of a light source corresponding to the complementary color among light sources of the light source unit.
