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.
1. Size: The product sizes that the two technologies ultimately achieve are basically the same, and there

is not much difference. From the chip point of view, due to the vigorous development of the liquid crystal

industry, the implementation of LCoS is mainly a standard liquid crystal packaging process, roughly through

some ITO glass printing to achieve the circuit, and DLP's microreflector array its implementation method is

mechanically realized, each microreflector pixel has a very complex mechanical structure, therefore, the

reduction of pixel distance on the process to improve the requirements are very high. The difficulty is

relatively much greater than that of the LCoS implementation.
2. Color purity: LCoS through technological progress, through the color sequence type to achieve, the

theoretical implementation of the hair style has been basically the same, so the color purity has been

basically the same, have been higher than the monitor and TV.
