Lasers have been used in a variety of industries since their inception, such as the laser pointer projection industry. The laser projector uses a laser beam to transmit the image. The optical components of the laser projector are mainly composed of red, green and blue light valves, a combined X prism, a projection lens and a driving light valve. There are red, green and blue lasers in the laser projector.
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 laser is transmitted to the projection screen by the projection objective to complete the entire laser projector display process. .
We know that the current mainstream projector solutions are DLP and 3LCD, in which 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 pointer 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.
The concept of laser projectors has been said for many years, and related products have been listed and applied in real life. Such as the outdoor projection display of the stadium of the 2008 Games and the display application of some cinemas. But laser projectors in the office, education, and home entertainment markets are still rare.
The comprehensive performance of laser projectors is very good, and laser projectors with few products in the retail market have been around for many years. Not emerging technologies, all aspects are very mature. At the same time, the Mitsubishi laser TV with the same working principle was launched this year, and BenQ also launched a laser projector. It can be seen that more and more companies are working on laser applications. The author believes that the future development of laser projectors will definitely have a lot to offer.
Laser TV is a laser pointer light source projector and projection screen using reflective ultra-short-focus projection technology, which can also display a good picture in a high brightness environment. The external laser TV is generally equipped with an intelligent system. The hardware inside is basically the hardware used by the smart TV. The Android system cooperates with some Mstar chips to realize the functions of playing large movies online, playing games, downloading applications, and so on.
From the industry exhibitions, laser, 4K, AV, etc., is the highlight of the audiovisual industry. From the full use of laser as a projection light source by LCD projection manufacturers, it can be seen that although its own advantages are irreplaceable in their respective fields, the inevitable avoidance of laser light sources is an inevitable trend accepted by all manufacturers and users.
In the popular consumption concept, the concept of flat-panel TV is still deeply ingrained, and the projector is still considered to be "yangchun white snow" to some extent. However, we can analyze the online shopping user data of flat-panel TVs, whether the proportion of projectors purchased at the same time or the proportion of projectors searched at the time of purchase is increasing year by year. This reflects to a certain extent that people's attention to the projector is increasing. Due to the shortage of production lines, the laser machine can not reduce the price in a short period of time, and people lack the popularity of projector knowledge. Although the obstacles exist, the progress is still bright.
