In 2016, what is most noticeable in the display technology field is undoubtedly the "laser display." The core of the laser display is a laser light source; with this light source technology, the value of the combat power of the projector is bound to soar. Recalling the entire 2016, the laser projection market gradually opened up, showing a rapid growth. According to statistics, 2016 sales of laser projection products were 110,000 units, which was 4 times the same period last year. This also signifies that laser projection has entered an era of all-round development.
Edit summary:
Looking at the current situation, three lasers, phosphors, blue lights, and LED+ lasers will coexist for some time. From the perspective of the development of technology, three-color laser will eventually occupy the entire projection market. However, in the application of laser display technology, Chinese companies have taken the lead in the world. As the fourth-generation display technology, laser display gradually guides the development of global display technology. Laser display will be ubiquitous in the future.
Lasers have to change the landscape of the future projection market
2017 will be the first year of the laser explosion. After years of development of the projector market, from a technical point of view, the main core trend technologies include: 4K, laser, and ultra-short coke. Technological innovation is the core driving force within the industry. After many years of development and accumulation in the projection industry, the projection innovation technology has developed into the projector market to continuously input fresh vitality. At present, laser display technology mainly includes three technologies: three-color laser, phosphor + blue light, and LED + laser. Each light source has its own advantages and disadvantages. In comparison, the advantage of three-color laser is obvious. Three-color lasers are the labels of high-end laser projectors, and projection equipment using this technology can easily achieve brightness of more than 20,000 lumens. The phosphor corresponds to the low-end projector, the highest brightness just broke 10,000 lumens. The LED and laser hybrid light source technology is aimed at the low-end market. The terminal display device adopting the technology has a brightness of no more than 3,000 lumens.
Three-color laser light source Three-color laser light is regarded as the most pure laser light source in the industry. It has the advantages of rich colors and high color saturation. It can display the richest, brightest and most realistic colors in nature, becoming a major technological development in the field of display technology. direction. As of now, the projection equipment using the three-color laser technology has "infiltrated" into the fields of simulation, exhibitions, convention centers, outdoor curtain walls, digital cinemas, home theaters, etc. It has great development space and broad market application prospects.

Phosphor + blue laser
The laser phosphor display technology uses a monochromatic laser (ie, a blue laser) in conjunction with a multi-color rotating fluorescent pink wheel technology that includes red, green, and other phosphors to generate red, green, and blue primary colors. Laser phosphor light source technology has overcome the fundamental technical difficulties of laser display in terms of efficiency and reliability. The application of laser phosphor display technology solves the problem of laser display in cost, environmental protection and user experience. However, due to the nature of the light source, the phosphor laser projector can only be implemented with a single-chip DLP, which cannot be applied to the large-screen market due to its monolithic nature. At the same time there is a certain lack of color accuracy. Laser+LED hybrid light source
One of the biggest advantages of laser+LED hybrid light source technology over traditional projection light bulbs is its long life. The new hybrid light source combined with laser and LED can make the life of the projector light source up to 30,000 hours, reducing the maintenance cost and the use cost. And in the long term, the brightness decay is not obvious. At present, this kind of combination situation has been rarely used in the market because of the limited brightness of LED light sources, and this kind of scheme is more complicated, and its future development prospect is not very clear. Looking at the current situation, three lasers, phosphors, blue lights, and LED+ lasers will coexist for some time. From the perspective of the development of technology, three-color laser will eventually occupy the entire projection market. However, in the application of laser display technology, Chinese companies have taken the lead in the world.
