The Science of a Laser Projector

This is a surprise, if I tell you about a display system, so far in color to replicate just mocked the LCD or OLED blush? In the past decades, we have from the CRT, LCD, approaching OLED displays. Have some more advanced coming in the next five to ten years - laser projector. One of the red laser diode array is ideal for light, projector, etc.

Generally speaking, the display combining red, green, and blue lights can create color images. Based on laser technology, laser display in general, they guarantee in key advantage and advanced definition, color gamut of 150% - 70-90 percent) and far LCD (OLED (100%). These three kinds of laser, red laser diode array must be able to provide high brightness and efficiency and management ability in room temperature to apply projection equipment.
Lasers offer the following advantages in serving as display light sources.


• Definition can be increased thanks to the excellent light-focusing characteristics of lasers.
• Good monochromaticity of laser light can make sure excellent color reproduction. Imagine the most brilliant colors you’ve ever seen; a red so bright and crisp its comparable to a street light.
• Since the light is polarized, superior optical efficiency can be achieved without using optical elements to align polarity when lasers are used in conjunction with liquid crystal panels.
• Laser light originates last longer than lamps – about ten times as long, approaching 15,000 to 20,000 hours.
Building a laser light projector source needs the combining of red, green and blue lasers (capable of generating optical output as high as several watts). Sony has remained a leader in the development of laser displays, containing the development of compact laser light sources capable of high optical output power.
