The imaging principle of the projector is actually relatively simple, all of which are displayed through the reflection of the lens, and the projectors we often use are mainly divided into three display technologies, LCD, DLP, and 3LCD. Let's take a look at the imaging principle of the projector.
1. LCD display technology
Commonly known as a slide projector, it uses an LCD screen as a display panel. The image quality is relatively general, mainly because of low cost and low price.
2. DLP display technology
DLP technology is used for DMD Texas chip, which is digital light processing technology. This kind of projector should be bought as high-end as possible.
3.3 LCD Display Technology
3LCD is imaged by three LCD display panels. This technology requires better fusion technology. At present, only Epson uses this type of display technology.
I believe that after reading the imaging principle of this projector, you will have a certain understanding of the display technology and imaging principle of the projector. In fact, it is still relatively complicated. LCD is divided into single-chip LCD and 3LCD, and the light source of opto-mechanical can be light bulbs or LEDs. DLP display technology can also use light bulbs or LED light groups, which can be further refined. separated. In short, everyone only needs to understand the display technology of projectors, and DLP and 3LCD display technologies are currently the most mainstream.
