When purchasing a projector, we often see a variety of projectors such as DLP Projector and LCD Projector. Then, what is the meaning behind them? What kind of people are they suitable for? Let's find out together.
DLP is a display technology used in projectors and rear projection TVs. It is an acronym for "Digital Light Processing", which means that the technology must first digitally process the image signal and then project light. More specifically, DLP projection technology uses a digital micromirror die (DMD) as the main key processing element for digital optical processing.
In addition to DLP, there are also CRT, 3LCD projection technology. CRT is the abbreviation of Cathode Ray Tube. As a display technology, it is the earliest and most widely used in projector. With the development of imaging technology, due to the complicated debugging and huge volume and weight of CRT projector, the current application of this CRT technology is less and less.
The principle of 3LCD is that the strong light emitted by the optical system passes through the beam splitter to form three channels of RGB light, and then respectively passes through the RGB three-color LCD panel. The signal source is converted by AD, modulated and added to the LCD panel. Then, by controlling the ON and OFF of the liquid crystal unit, the on-off of the optical path is controlled. Finally, the RGB light is converged in the prism and projected onto the screen through the projection lens to form a color image. The technology of 3LCD is originally controlled by Epson and Sony, and the projector manufacturers using 3LCD technology in the market are mainly Epson.
For Home Theater Projector and Business Projector, most of the imaging technologies used are 3LCD and DLP. In addition, DLP projector has won the favor of many users due to its lower power consumption on the basis of the same brightness and resolution, and the fact that the screen projected by the machine will not turn yellow as the machine is used for a long time. Take HOTUS H2 as an example also, 350ANSI Lumens brightness, 1280*720 native resolution, support 2K or 1080p resolution, 30000 hours LED light source life, with 10000mAh built-in battery, can be used normally for 2 hours without charging.
To sum up, if you are purchasing a DLP Projector for Business Office, Home Theater and Teaching, you are welcome to consult us and we will offer the pertinent advice and nice price for you and your business.
