Maybe many people will ask what ALPD is, and how is it different from other projection technologies? Today, the editor will take a look at the principles of ALPD projection technology.
1. ALPD projection technology
ALPD is the abbreviation of "Advanced Laser Phosphor Display", which is the advanced laser fluorescence display technology. ALPD uses fluorescent materials based on GaN blue laser excitation motion to generate one or more primary colors for image display, which is the most critical core technology for high-brightness image display.
The schematic diagram of the ALPD laser light path. Traditional image display devices use light sources such as HID and other high-brightness bulbs to display color images. However, these bulbs face the shortcomings of short life, low efficiency, and contain toxic materials. Since the invention of LED, due to its high efficiency and long life, it has been rapidly applied to image display devices such as TVs. However, although LED technology continues to progress and can provide a larger luminous flux, it is limited by a larger optical expansion, and its brightness cannot provide high-brightness display requirements. Mercury lamp.
The laser has good directivity, and the laser spot can be focused into a tiny (at least a few micrometers in diameter). Its brightness is not only 100 to 1,000 times higher than that of LED, but also higher than traditional high-brightness xenon. The lights have also been greatly improved. However, its high cost, low electro-optical conversion efficiency and reliability greatly restrict the application of lasers in the field of display.
ALPD fluorescent laser technology retains the inherent high brightness of traditional lasers, while using the basic technical route similar to mainstream LED lighting and display blue light plus fluorescent materials, innovatively invented remote rotating fluorescent devices, ingeniously solved the fluorescence Conversion heat quenching problem, under the excitation of high-density laser, still maintain high conversion efficiency. At the same time, the use of GaN blue laser and YAG and nitride fluorescent materials effectively continues the advantages of high reliability and long life of LED. ALPDTM laser light source has the advantages of traditional laser and LED, and solves the shortcomings of both. It is a disruptive new type of light source and a major breakthrough in the history of lighting technology.
2. Summary
ALPD laser light source projection technology is the leading laser phosphor display technology in the projection industry. ALPD uses fluorescent materials based on GaN blue laser excitation to generate one or more primary colors to achieve image display, which is the core of high-brightness image display. Key technology. ALPD technology has a series of characteristics such as high brightness, long life, low cost, small size, low energy consumption, and good image quality. It is currently the world's leading laser light source projection technology solution.
