Application scope: LED has the widest application scope and can be found in various occasions. At present, DLP is mainly used for monitoring and demonstration. The disadvantage is that the light bulb needs to be changed frequently and the price is not cheap. However, the effect of mosaic display is very good, and seamless splicing can be achieved. PDP can also be monitored, but the splicing effect is not as good as DLP, and the seam is large and easy to burn.
Market supply and demand: DLP has the largest market at present.
Advantages: LED has high brightness, bright colors, convenient maintenance, low installation environment requirements and long service life.
DLP has small seam, high contrast and fast response. High resolution.
PDP has higher brightness and larger viewing angle than liquid crystal. Its size is relatively small, suitable for use in places with small housing area.
Disadvantages: low LED resolution and high maintenance rate.
DLP needs to change the light bulb frequently, which occupies a large area.
PDP seam is easy to burn at a certain position.
