A laser projector uses a laser beam to transmit a picture. The laser is diffused in the machine through the corresponding optical components and processing chips and then transmitted to the X prism to integrate the three lasers, and then the integrated objective lens is transmitted by the projection objective to the projection screen to complete the entire laser projector display. process.
At present, the mainstream projector schemes are DLP and 3LCD, wherein the 3LCD is to transmit the red, green and blue liquid crystal panels through the lens magnification and the mirror. The DLP works by mixing the light through the color wheel at high speed. Finally, it is transmitted through the prism. Although each has its own advantages, it should be noted that both methods are to use the bulb, the bulb has a long life, and the brightness of the picture and the purity of the color can only be considered relatively sufficient.
The laser projector is to make up for the defects of the 3LCD and DLP projection methods. That is, the working life is long, and the brightness of the screen is not dimmed due to long-time work; the color gamut is wide, which is about twice the color gamut of an ordinary projector.
At present, the global laser pointer projection industry has formed a three-legged industrial structure dominated by the United States and Canada, Asia and Europe. In terms of patent layout in the field of laser display, the United States and Japan are the leaders, followed by mainland China.
Changes in various fields have generated huge demand in the laser projection market. Education information transformation, using modern information technology, innovative education concepts and teaching models to improve teaching effectiveness and reduce maintenance costs; enterprise informationization upgrades, data visualization changes, and exhibition display areas highlight high energy consumption, high definition, special shape, large size The requirements of other aspects have put forward higher requirements for real technology. Smart homes drive large-scale, mobile, and intelligent display, and put forward higher requirements for product portability and flexibility. Laser TV meets development needs and will become the second screen in the living room.
As the display technology with the purest color, the highest brightness, the highest luminous efficiency, the most stable use and the best creativity, laser projection has a broad application prospect in the future.
