The imaging technology of projector can be divided into two categories: 3LCD and DLP technology. The former is patented by Epson, and the latter is patented by Texas Instruments. Both have their advantages and disadvantages. 3LCD has good brightness and convenient installation, but the pixel structure is obvious and the gray scale is less, while DLP pixel structure is more comfortable, with more gray scales and less crosstalk.
Relatively speaking, DLP technology will have a slight advantage, and DLP technology is also the mainstream projection imaging technology in the market at present.
When using the projector, you should pay attention to the following items:
1. Try to use the original cables and wires of the projector.
2. When using the projector, please stay away from water or damp places to avoid getting wet.
3. When using the projector, keep away from the heat source and pay attention to heat dissipation.
4. Pay attention to the nominal value of the projector power supply voltage, the grounding wire of the machine and the polarity of the power supply.
