Compared with LCD and DLP projector technologies, LCOS projection technology has the potential of high resolution, high brightness, and low cost, and is the star of projection technology.
1. The biggest feature of high-resolution LCOS projection technology is that the lower substrate of the panel uses a silicon wafer CMOS substrate. Since the material of the lower substrate is monocrystalline silicon, it has a good electron mobility, and the single crystal silicon can form a finer one. Lines, so it is easier to produce high-resolution panels.
2. High-brightness LCOS is a reflective technology that does not significantly reduce light utilization as the light from the LCD optical engine penetrates the panel. Therefore, the light utilization rate can be increased to 40%, which is comparable to the 3% of the transmissive LCD. In contrast, it can reduce power consumption and produce higher brightness.
3. The low-cost LCOS optical engine has the advantage of low cost because of its simple product parts, plus the huge investment of Taiwanese manufacturers, compared to the LCD panels supplied by Epson, Sony, and DLP, which is exclusively supplied by Texas Instruments. Panels, LCOS has a rapid decrease in cost.
However, LCOS technology itself still has many technical issues to overcome, such as: black and white contrast is not good, three-chip LCOS optical engine is larger. Although LCOS has some technical advantages, LCOS projectors are still in the minority in the market. The main problem is that the mass production technology has not yet been overcome and the supply of parts is still unstable. Therefore, LCOS still needs to take time to become a projector. Mainstream technology.
