Projection display apparatus

Abstract

A projection display apparatus comprises luminous bodies, a luminous body driving portion which drives to turn on each of the luminous bodies, light leading members which optically separately lead and project light beams exiting from the luminous bodies, a movable portion which enables relative movement of the light leading members and the luminous bodies, and a light selection control portion which controls the movable portion and/or the luminous body driving portion in such a manner that light beams which enter the light leading members are selected. The apparatus further comprises a light modulation element which performs light modulation, an illumination member which illuminates the light modulation element with light beams from the light leading members, and a display control portion which controls the light selection control portion and the light modulation element in such a manner that the element suitable for light beams from the light leading members is illuminated.

1 . A projection display apparatus comprising: 
 a first illumination unit configured to emit one of red light, green light and blue light;    a first light modulation element configured to modulate said on of the red light, green and blue light, which is emitted by the first illumination unit;    a second illumination unit configured to emit the other two of the red light, green light and blue light in time sequence;    a second light modulation element configured to successively modulate the other two of the red light, green light and blue light, which are emitted by the second illumination unit;    a combination section configured to combine said one of the red light, green light and blue light, which is modulated by the first light modulation element, and the other two of the red light, green light and blue light, which are modulated by the second light modulation element into light;    a projection lens configured to project the light obtained by the combination section; and    a synchronization control portion configured to control emission timings of the other two of the red light, green light and blue light, which are emitted in time sequence by the second illumination unit, in synchronism with modulation of the other two of the red light, green light and blue light, which is performed by the second light modulation element based on color data items included in image data for use in modulation by the second light modulation element.    
   
   
       2 . The projection display apparatus according to  claim 1 , wherein said one of the red light, green light and blue light, which is emitted from the first light illumination unit, is the green light, and the other two of the red light, green light and blue light, which are emitted from the second light illumination unit, are the red light and blue light.
