With the widespread penetration of products such as laser TVs and laser smart micro-projectors in the consumer market, the laser projection display, known as the fourth generation of display technology, has begun to really break into the public eye. So, you may be curious: what is so special about the laser projection display technology, why can you directly compete with OLED? How to get to the center of the audiovisual industry stage?
The laser display uses red, green and blue (three primary colors) monochromatic laser pointer with a higher power (watt level) as the light source, mixed into full color, using a variety of methods to achieve line and field scanning, when the scanning speed is higher than the imaging The critical flicker frequency can meet the requirements of the human eye "visual residue", the human eye can be clearly observed. The critical flicker frequency should not be lower than 50Hz. In the color gamut that the human eye can see, the liquid crystal can only reproduce 27%, the plasma is 32%, and the theoretical value of the laser exceeds 90%.
As early as the late 1980s, the rapid development of high-power semiconductor laser (LD) technology, all-solid-state laser (DPL) technology and micro-display system technology, which originated in the military industry field, made the laser display technology begin to move towards practical use, especially Laser projection display technology.
However, until the end of 2013, the American and European standards had limited open standards, and high-power laser projection began to appear legally, making the development of laser projection into a new era. Subsequently, major domestic and foreign laser display brands including Barco, Christie, and division successively released new laser products. For example, as early as the beginning of 2014, the local company Dewey Vision launched the world's first 4K resolution 50,000 lumens green laser pointer projection system.
Nowadays, under the dual drive of market demand and technological breakthroughs, the expansion of laser projection applications has become an irreversible trend. In addition to destroying cities in traditional superior markets such as command and control, video conferencing, education and teaching, the laser display technology is also becoming a new territory in the cultural and entertainment market where demand is increasing.
