Industry characteristics and prospect of LCOS projection technology depth interpretation

Published:2014-02-19 Sources: Views:1412

The abbreviation of LCOS (Liquid Crystal on Silicon. Chinese named monocrystalline Silicon reflection type Liquid Crystal) is an integrated LCD with CMOS integrated circuit of reflective display technology, with high resolution, high pixel area share, light consumption of small, fast response speed, small volume, light weight, etc. LCOS projection technology owns almost all the advantages of the DLP technology and LCD technology, at the same time very good to overcome the shortcomings of them. This is the so called projection LCOS products industry future star. However, LCOS industrialization road is not smooth. LCOS industry become the projector product type led technology at present there are two main types of reasons. One is the problem of yield, and the other is the competition from rival DLP.

 


LCOS chip need to be highly polished aluminum layer closely combined with the liquid crystal molecules on the material. This step is the key to leading to a lower yield LCOS chip. Liquid and solid surface precision, meet the needs of the excellent optical imaging with the accuracy of the LCOS chip is the main aspect of process improvement. Yield problems as a direct result of LCOS projector price does not have a good competitive advantage. Especially the monolithic and full hd resolution under DLP products compare, DLP products are often lower than the price of the LCOS product a lot.


On the industry competition, LCOS biggest advantage is not formed similar to the LCD and DLP projector that monopoly. Chip only Texas instruments have technology of DLP projector and commissioned the production of enterprises is also very limited. LCD technology chip technology is relatively better. Master by SONY and epson two companies. However, to provide enterprises only epson chip and light machine. SONY LCD products mainly for personal use. And SONY on high-end products have already completed the transformation of lcos technology.

 


The pattern of this core technology monopoly is bound to cause industry development lag. Especially in the LCD industry, with chip technology enterprises is the main terminal, which inevitably cause their customers are our main rivals. DLP technology holders of Texas instruments projector product itself does not produce, thus avoiding the competition, the upstream manufacturers and companies formed a good industrial value chain. The DLP products in the global market both in the size of the market and support the number more than LCD products.

And the LCOS industry at this point is more advantage. LCOS chip basic semiconductor industry and the LCD industry using mature type technology of the masses. This makes many companies can skip over the core patent threshold to develop our own products. To have a product of the core industrial chain is gain competitive strength and create more enterprise value of the good foundation. Only by this, LCOS projection enterprises can become the most popular, especially advocating creative manufacturing enterprise favorite technical types.

But none of the core enterprise to lead the LCOS industry also has its inherent weaknesses. That is not unified standard, power dispersion. The characteristics of such inevitable will leave more opportunities to competitors. At the same time, and LCOS projector can only obtain good market performance in the field of those who pay attention to the performance of one of the reasons. Since LCOS cost advantage need large-scale manufacturing, while the scale of manufacture must be based on a unified industry standard.

On the whole, for the projector industry has maturity, LCOS technology is still a young baby. But the child born clever, gifted, owner of the limit in the future. Especially for industry and domestic projection, if you really want to do big things, LCOS technology will be the most promising breakthrough point.
