Home theater LED light source revolutionary upgrade

After the development of the home projector entered the era of full HD, it gradually entered a steady progress. After all, the resolution of 1920X1080 is enough for large-screen projections below 200 inches. More importantly, the full HD signal source is very mature, and the full HD industrial structure is very perfect. After slowing down the pace of chasing higher resolutions, major manufacturers made a big fuss on the full HD projectors and conducted in-depth technical research. In addition to the very popular 3D projection technology in recent times, LED light sources have many advantages such as long life, wide color gamut, low heat generation and environmental protection. The use of LED light sources in home projectors is also a hot spot for many manufacturers and users.
In fact, for the projector, it is not difficult to realize 3D display. The home 3D market is currently dominated by a shutter-type 3D solution. The technology of this technology is not very high, as long as the existing models are available. The corresponding technical transformation can be completed, so recently there are manufacturers to release 3D 720p HD projectors, such as Acer (Acer) H5360, Optoma (Otto code) HD66 and so on. It is not an easy task to use the LED light source in the home projection. The change of the sub-lighting mode will inevitably completely change the optical path structure inside the projector. Only a new model can be realized, which is for each projector. The research and development capabilities of manufacturers are a test. At the same time, the biggest problem encountered by LED light sources has been the low output brightness, resulting in a lack of aging and dull projection images. However, in the past two years, the development of LED light source technology has made a breakthrough, and the output brightness has been greatly improved, especially in the ERGB three-color LED light source. This led to the rapid development of micro projectors and the technological revolution of monolithic DLP home theater projectors using RGB three-color LED light sources.
LED, the full name is Light-Emitting Diode, which emits light through directional electron motion in the semiconductor. LED light source is a young light source technology. Although it was first discovered by Mr. Rubin Braunstein of American Radio Company in 1955, due to technical reasons, it was not until 1993 that Nakamura was working in Japan’s Nichia Chemical Industry. Mr. has developed a blue LED with commercial application value, and then launched a new page in the development of LED light source technology. Since blue is one of the three primary colors, the lack of a blue LED cannot produce a white LED system or a white LED, and thus cannot be applied to the field of display devices. It can be seen that the real commercial development of LED light sources is more than ten years.

LED white light sources currently used on display devices are mainly classified into RGB white LED systems and phosphor white LEDs. RGB white LED system is a white light system composed of blue LED, red LED and green LED. The white light produced by this kind has a very wide color gamut and is mainly used in home projectors and high-end flat-panel TVs. . The phosphor white LED light source emits shorter wavelength light through a single light emitting unit, and then converts part or all of the light into one or more other colors of light (longer wavelength light) with the phosphor, when all the light is mixed. Then you can form white light. Relatively speaking, such white LED light sources are relatively low cost, but the color gamut is far from wide in RGB LED systems and is often used in low-end display devices.
