Abstract:
A projection type video display includes a light source including light source parts, which are the LED arrays each including six LEDs, for every predetermined colors; a light source controller time-division driving each of the light source parts at a timing based on an input video signal to be input from the outside; and a video display device modulating light emitted from each of the light source parts based on the input video signal and projecting the modulated light onto a screen, wherein the light source controller controls only three LEDs among the six LEDs to turn on in each driving of the time-division driving of each of the light source parts.
