DLP and LCD are two optical technologies used in projectors.DLP digital optical processing technology is used to project light by putting the image signal through digital processing. LCD liquid crystal display technology, on the other hand, uses the wide-range effect of liquid crystals to produce images with different grey levels and colours.
In addition to the different technical principles, the main differences between DLP and LCD include colour capability, contrast ratio, dark picture capability, colour separation and reproduction capability.LCD projectors have good image colour saturation, rich layers, good colour separation, and strong reproduction capability, but with lower contrast ratio and weaker dark display capability; DLP projectors have higher contrast ratio, and rich representation of dark and light details, but with comparatively poorer colour capability .
In general, a few hundred dollars of projectors, are used in the monolithic LCD technology, this projector is sold very cheap, the price is between 100 ~ 1000, monolithic LCD projection principle, is the use of light projection LCD liquid crystal plate projection imaging principle, the most expensive components inside the machine, that is, a LCD liquid crystal plate, the cost is very low. This type of LCD projector is characterized by low light efficiency, low contrast, narrow colour gamut, poor colour, short life, buy home with a half a year or so may be in condition, low price, but the cost-effective is also very low, so it is not recommended to buy.
What are the advantages of DLP projectors? In summary, DLP is characterised by: high light efficiency, high contrast, long life, high precision and high cost of process difficulty. Hotus H2, for example, most of the DLP projector with Germany Osram lamp beads, long life, most businesses are advertised as 30,000 hours of service life, according to the daily 8 hours of use time, can be used for 10 years, this cost-effective can not be said to be not high.
