The PhlatLight LEDs are also used in a new class of ultra-compact DLP front projector commonly referred to as a "pocket projector" and have been introduced in new models from LG Electronics (HS101), Samsung electronics (SP-P400) and Casio (XJ-A series). Home Theater projectors will be the next category of DLP projectors that will use PhlatLight ...

Most cue marks appear as either a black circle (if the physical hole is punched out on the negative used to make the projection print of the film), or a white circle (if the mark is made by punching a hole or scraping the emulsion on the positive film print). They will also appear as an oval if the print is projected through an anamorphic lens.
In contrast, a modern LCD or DLP projector often uses an Ultra-high-performance lamp which has a higher luminous efficacy and lasts for thousands of hours. [5] A drawback of that technology is the warm up time required for such lamps. Older overhead projectors used a tubular quartz bulb which was mounted above a bowl-shaped polished reflector.
