发明名称 MULTIMEDIA PLAYER DISPLAYING 2 PROJECTION IMAGES
摘要 An apparatus for reproducing multimedia is provided to display two clear projection type images constantly even without setting an optical system whenever the apparatus is used. A first projection unit(12) displays a first projection type image. A second projection unit(14) displays a second projection type image. The first projection unit includes a first driver(102) for controlling the operation of the first projection unit and providing a first image signal for the first projection type image to be displayed, a first light source unit(112), a first light modulation element(122) for modulating the light supplied from the first light source unit according to the first image signal to output the first projection type image, and a first projection lens unit(130) for enlarging and projecting the image outputted from the first light modulation element. The second projection unit includes a second driver(104) for controlling the operation of the second projection unit and providing a second image signal for the second projection type image to be displayed, a second light source unit(114), a second light modulation element(124) for modulating the light supplied from the second light source unit according to the second image signal to output the second projection type image, and a second projection lens unit(134) for enlarging and projecting the image outputted from the second light modulation element.
