Laser projectors use laser beams to transmit images. Among them, the optical components of the laser projector are mainly composed of red, green and blue light valves, beam combining X prism, projection lens and driving light valve. There are red, green and blue lasers in the 2K laser projector.
After the beam expansion of the corresponding optical element and processing chip in the machine, the laser is transmitted to the X prism to integrate the three laser beams. Then the projection objective lens transmits the integrated laser light onto the projection screen to complete the entire laser projector display process.
The current mainstream projector solutions are DLP and 3LCD. Among them, 3LCD is a red, green, and blue liquid crystal panel that is enlarged through a lens and transmitted through a mirror. In the DLP working method, the light is mixed at high speed through the color wheel, and finally transmitted through the prism. Both projection methods have their own advantages and disadvantages. It should be noted that these two projection methods can use a light bulb or a laser as a light source. However, the bulb has a service life, and the service life of the bulb is usually much lower than that of the laser, so the bulb needs to be replaced after a period of use. And the brightness of the bulb's picture and the purity of color can only be regarded as relatively sufficient.
2K laser projector
is to make up for the defect of the lamp projection. It has a long working life and will not dim the screen brightness due to long-term work; it has a wide color gamut, which is about twice that of ordinary projectors.
The overall performance of laser projectors is very good, and laser projectors in the retail market have been around for many years. Laser projectors are not an emerging technology, and are very mature in all aspects.
