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 ...

3. Spatial light modulator - Wikipedia

   en.wikipedia.org/wiki/Spatial_light_modulator

   An example of an EASLM is the digital micromirror device (DMD) at the heart of DLP displays or LCoS Displays using ferroelectric liquid crystals or nematic liquid crystals (electrically controlled birefringence effect). Spatial light modulators can be either reflective or transmissive depending on their design and purpose. [4]

4. Rear-projection television - Wikipedia

   en.wikipedia.org/wiki/Rear-projection_television

   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.

5. Light-emitting diode - Wikipedia

   UV LEDs, with spectra range of 220 nm to 395 nm, have other applications, such as water/air purification, surface disinfection, glue curing, free-space non-line-of-sight communication, high performance liquid chromatography, UV curing dye printing, phototherapy (295nm Vitamin D, 308nm Excimer lamp or laser replacement), medical/ analytical ...

6. Overhead projector - Wikipedia

   en.wikipedia.org/wiki/Overhead_projector

   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.

7. Digital micromirror device - Wikipedia

   en.wikipedia.org/wiki/Digital_micromirror_device

   A DMD chip, used in most projectors and some TVs. The digital micromirror device, or DMD, is the microoptoelectromechanical system (MOEMS) that is the core of the trademarked Digital Light Processing (DLP) projection technology from Texas Instruments (TI).
