Laser marking machine: talk about the working principle of laser display technology
For friends who want to buy laser equipment, laser Leadtech Coding machine is recommended here - Guangzhou Lianda Laser Technology Co., Ltd. This company is a professional manufacturer of intelligent laser equipment, proficient in product manufacturing and software development, with a large number of optical, mechanical and electrical professionals, can provide customers with laser equipment with stable and reliable quality and diversified functions. Next, let the laser coders talk about: the working principle of laser display technology.
First of all, let's talk about the laser display system: the laser display system is mainly composed of three primary color laser light source, optical engine and screen. The optical engine is mainly composed of red, green and blue light valves, beam-combining X prisms, projection lenses and driving light valves. The light valve drive generates small images corresponding to red, green and blue colors on the light valve, and then introduces three colors respectively. Color laser illumination is projected onto the screen, that is, a full-color display image is generated. Acting as light valve and driving source can be various micro display systems, such as LCD, LCOS, DMD, GLV and so on.
The working principle is that the red, green and blue lasers are incident on the corresponding light valve after beam expansion, shimming and decoherence respectively. The modulated three-color laser is combined by the X prism and then incident on the projection objective lens, and after Z is projected onto the screen through the projection objective lens, the laser display image is obtained.
