My review of the Vivitek H9080FD LED home theatre projector shall be appear in The Canberra Times on Monday, and I’m hoping to look at a Runco LED projector next week. But I’ve been thinking: must LED projectors be limited to DLP projectors?
LED projectors use three powerful LEDs — one each for red, green and blue — instead of a lamp. Because of the individual control of each colour, the colour wheel normally included in a single-chip DLP projector is dispensed with.
But is there any reason why LEDs cannot be used for 3 chip projectors, such as LCD or LCoS models? Presumably all that needs happen is the three colours to be physically separate, rather than packaged together.
