In the last article, we talked about the benefits of the laser projector, now we??d like mentioned something you must care about when purchasing the laser projector.
There are many models to be optional on the market and each one counter different prices. You may get confused about why some models are cheaper or more expensive, how do you choose? Here, I want to advise two key points for you:
The different chip will totally counter different prices, 0.47 DMD with great prices but maybe not perform very well in brightness, test result shows it can achieve at most 1200-1600lum. Another disadvantage of 0.47chips is it not suitable for big screen, it may occur color fading in size like 100inch. The latest DLP technology used in the projector now is 0.65DMD, which have much improved in both problems.
2.Fewer lasers, lower prices.
You may also notice that laser source has a pure laser and hybrid laser. Pure laser working structure is: Laser source with phosphors to create light as following picture shows.For hybrid source, working structure is: LED source+ Laser source+ Phosphors. One benefit of the hybrid is saving cost.
Use the hybrid source, it may emerge three questions:
2.1 Hybrid SSI(ReD +Laser or Red/Blue+Laser)will generate imbalance question due to different color source.
2.2 Due to the large light-emitting angle of the LED, the light-emitting angle relative to the laser light source is small, and the optical system can not collect more light energy to increase the brightness by increasing the number of LEDs, it will cause hybrid source with bad light collection efficiency, on account of this, it will reversely result in hybrid projector in high brightness mode must sacrifice color balance, if choose the color balance mode must sacrifice brightness, it will only 1500 lum.
2.3 Hybrid source (LED & Laser) efficiency decay trend inconsistent, long-term use will result in can not maintain color balance, will also affect the lifetime of the projector.
So many benefits of laser projector as I mentioned, but it still not popular in the market,why??In other words, What??s its disadvantage?That??s relatively expensive compared with a traditional lamp projector, So how much will it cost for a laser projector? The price will vary due to different chip and the laser source, different configuration required depends on your needs. Another solution for this disadvantage is IQ projector with 0.65DMD, pure laser projectors are in end-year promotion, you can get this product with best prices ever, If you’re interested, don’t miss this opportunity.
Any market to accept new products will take time, the thing we can do is to go ahead than others, or we will leave behind them. Lasers provide unparalleled superiorities, there is no doubt that laser projectors would be the future of the projectors!
