2. Digital light processing - Wikipedia

   en.wikipedia.org/wiki/Digital_Light_Processing

   Logo The Christie Mirage 5000, a 2001 DLP projector. Digital light processing (DLP) is a set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the ...

   LED projectors use one of the above-mentioned technologies for image creation, with an array of light-emitting diodes (LEDs)as the light source, negating the need for lamp replacement. Hybrid LED and laser diode system developed by Casio. Uses a combination of LEDs and 445 nm laser diodes as the light source, while image is processed with DLP chip.

   UHP lamps used in projectors and RPTVs require periodic replacement, as they dim with use. The first wall-mountable RPTV was launched in 2003 by RCA. The first DLP 1080p RPTV was launched in 2005 by Mitsubishi. The first RPTV to use LEDs instead of an UHP lamp as its light source was released by Samsung in 2006.

   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.

8. Ultra-high-performance lamp - Wikipedia

   en.wikipedia.org/wiki/Ultra-high-performance_lamp

   Ultra-high-performance lamp. An ultra-high-performance lamp, often known by the Philips trademark UHP, is a high-pressure mercury arc lamp. [1] These were originally known as ultra-high-pressure lamps, [2] [3] because the internal pressure can rise to as much as 200 atmospheres when the lamp reaches its operating temperature.

9. LCD projector - Wikipedia

   The basic technique is to combine a high color-rendering index (CRI) high-intensity discharge lamp (HID lamp) and ballast with a condenser and collector Fresnel lens, a single color LCD removed from a common computer display or electronic device and a triplet lens. This design can also be used in low cost (around US$200) LCD projectors. [11]
