We know that the current mainstream projector schemes are DLP and 3LCD, in which 3LCD magnifies the red, green and blue LCD panel through a lens and transmits it through a mirror.
The DLP working mode is that the light passes through the color wheel and rotates at high speed to mix colors. Finally, it is transmitted through a prism. Although each has its own advantages and disadvantages, it should be noted that both methods use light bulbs, which have a long life, and the brightness and color purity of the picture can only be considered sufficient.
From this year's industry's largest Jingmei InfoComm exhibition, we can see that laser, 4K, AV and so on. Are the most eye-catching highlights in the audio-visual world. It can be seen from the comprehensive adoption of laser as the projection light source by LCD projector manufacturers that although its own advantages are irreplaceable in their respective fields, the inevitable laser light source is also an inevitable trend accepted by all manufacturers and users.
