Technical comparison
DLP technology and LCoS technology comparison Speaking of the advantages and disadvantages
of DLP technology and LCoS technology, in fact, in the use of conference room (education) commercial
projectors, there is a dispute between DLP technology and LCoS technology, of course, as a micro
projection, although the general principle is similar, but because the implementation method is slightly
different, or some different, the following will also be from the above several technical indicators on a
detailed comparison.
Photoelectric efficiency: The brightness efficiency achieved by the two technologies is about the same,
with a light output of 7,8 lumens per watt. But from the perspective of the 2 technologies themselves,
LCoS requirements for signals can be directly accessed by the circuit, and DLP is realized mechanically,
on the main board carrying the DMD chip, there are corresponding processors (Processor) and memory
(Memory), this part of the power consumption in the optical engine as a whole can never be avoided, can
be considered as a disadvantage of DLP technology in efficiency, especially in the handheld projection
system, if you consider the heat dissipation problem, The advantages of LCoS chips are more obvious.
Relatively speaking, the power consumption of LCoS can be less than 0.1W, and in the long run, LCoS
will also have certain advantages.
