Projectors: the sequel

In my last blog I started talking about projectors. Everything that I have learned already is amazing! I knew there was a lot to projectors, especially now because of all the new innovative technology that has been created. So to continue where I left off. Too name some of the largest projector manufacturers out there; Barco, Sony, Texas Instruments, And NEC. IMAX just released it first laser projector.What this does is it uses lasers to project light onto the screen. There are even some projectors that are hybrids between LED and laser. Most projectors use xenon arc lamps to create the light, but they only last a little over 2,500 hours.before leading to be replaced. The main difference between laser and xenon is the higher contrast that laser projectors give off.  Newer projectors have higher frame rates(refer to third blog), great quality, system cooling, and brighter. Projectors are made to accommodate different sized screens(dimensions). Most projectors come with standard lens that are already set to match the distance and size of the screens. The cost of projectors from Barco usually cost an upward of $55,000 for 2k and $85,000 for 4k. When Robert told me this I didn't find it hard to believe. All this new technology is expensive. This then lead me to realize why ticket prices have gone up, they need to make a profit. In my final blog I want to know how modern cinemas manage all of their theaters.
