Overhead projectors for LCD panels are particularly bright, and start at about 3000 lumens, or about 2 to 4 times as bright as most older overheads. Instead of sending a projector in for repair, the manufacturer simply replaces it with one from a pool of identical projectors. Simply return your broken unit in the box the replacement arrives in. You will keep the replacement, and never be troubled by that old unit again. PAL A European and international broadcast standard for video and broadcasting.

Panels survive as the entry level products in every catagory. Typically the most expensive panel in a given resolution, sells for less than the least expensive projector. More expensive panels sell moderately well in SVGA and XGA resolutions due to the tremendous difference in prices between panels and projectors in those resolutions. Only one or two projectors use any type of passive matrix display. The defining description.
