I hope they step up that resolution. But yes cool for sure.

Cool. I wasn't aware of this tech. Who needs a shoebox? I've already rationalized hanging a volkswagon from my ceiling, just make something affordable!

What's the bandwidth needed for 1080P60?

Close to 200 MHz according to this guy. Interesting article.

Wow, tough crowd. Are you guys keeping in mind this thing is the size of a frickin' pack of cigs? iPod size? Come on, that's impressive, regardless of contrast ratio or resolution.
Here's an image from one of their larger machines:
RESOLUTION: >1920 x 1080
CONTRAST RATIO: >4000:1 sequential
COLOR COORDINATES: Laser source wavelengths: Red - 628nm Blue - 447nm Green - 532nm
UNIFORMITY: >90% edge to edge
RGB VIDEO BANDWIDTH: 100 MHz (or 150MHz available)
I also thought this was interesting:
Quote: | Specifications
Typical laser projector specifications:
Brightness: 500 lumens and greater.1
Resolution: 1920 x 1080
Contrast ratio: >3500:1 sequential
Color coordinates: Primary colors (see chromaticity diagram below):
Red laser – 628nm
Green laser – 532nm
Blue laser – 447nm
Uniformity: >90% edge to edge
1 Light output is determined only by the number of RGB lasers employed in the system. COLOR has built and delivered systems capable of greater than 4000 lumens output.
2 4x2k resolution has recently been demonstrated by JVC and Sony and will be commercially available this year. These systems are fully compatible with COLOR’s lasers. |
4kx2k - That's cool. If they've done high-res, and 4000 lumens, then the system has legs. They just need to crank up the contrast some. The only question is whether it could ever be made inexpensively enough for home use. The portable version is at least encouraging.

In its purest form, the laser can either be on or completely off... But, in their large setup, they're using the laser as a pure coherent light source in conjunction with LCoS. They must not be modulating the laser.
Quote: | COLOR’s laser video projection systems utilize proprietary diode pumped solid state (DPSS) red, green and blue lasers (RGB) developed and manufactured at COLOR. Lasers are coupled to liquid crystal on silicon microdisplay (LCoS) type projection systems to produce video images with high resolution, contrast ratio, uniformity, color saturation and virtually no speckle. The result is a remarkable presentation that truly needs to be seen to appreciate. |
If they were using only lasers without some kind of imaging chip, then they need to use multiple rotating mirrors to get V- and H-scan. You wanna talk big bucks, start sourcing optical mirrors and motors and bearings that can rotate at 50,000 RPM with super-tight tolerances. The complexity and expense of the components are the main reason I've never had any hope of a resolution-independent scanning laser-based display system replacing CRT - exciting as that would be.
So, this is still a fixed-pixel system. Hopefully, the system design has room for improvement, though.

I'd love to see this in portable wireless productivity devices, re:PDA's. Married to WiMax it will be a formidable portable productivity tool. IMO I think the product/technology will run into the same obstacle that prevents more subscriptions for delivered content (streaming TV, movies, etc) to current portable wireless products and that's battery life.
It's been my experience that people have unrealistic expectations of how long a battery should last and how often they should have to charge it DESPITE the stats for talk and standby times being in their manuals and NORMALLY explained to them before they purchase their handsets. (we do)
Although battery technology continues to change and mature it's changing too slowly for the power hungry devices being produced. That's the reason most devices such as the iPhone or iPod or devices of that ilk have such small displays. You want longer overall operating times (cell phone usage, productivity tools usage such as Outlook, M$ Office CE, etc) you have to go to devices like the BlackBerry, Palms, UTC Starcom PPC 6xxx series devices. There isn't any one device that delivers everything the most demanding customers need. A blend of 3 or 4 products I sell would make for the 'perfect' power user handset. That isn't going to happen due to exclusivity, licensing, yada yada.
The BB's, Palms, PPC devices, etc have large displays but the overall device is too 'huge' for alot of people yet they want the same features in a smaller package. However to support the display size and the amount of time that can slip away using the productivity software requires a bigger overall package to house the bigger battery.
I jokingly invented a shaker charger for use in larger devices such as PDA's (like found in emergency kit flashlights) but then decided to patent it. Granted it'll look strange to see people jacking off their phones out and about in public but
until battery technology can keep up with portable demands it seemed like a logical idea.
I also applied for a patent for a charger that utilizes the body's micro voltage to provide slowwwwww charges to portable devices. Regardless of how realistic or feasibile it is, if somebody smarter than I makes it work, I hold the patent which I'll GLADLY sell.
BOT, in my line of work a portable wireless device with a laser pj sure wouldn't hurt activations/sales even if the batteries are the weak link.

Interesting! I never would have thought to use laser as only the light source. This makes a lot of sense. Less heat. And no "bulb" to replace as it should last years and years I think.

Two completely different products are being linked to here. The original post links to Microvision's scanning laser pico projector "Show". It utilizes MEMS technology in it's scanning mirror, that produces an image pixel by pixel (same as crt raster-style scanning). It is only capable of 15-20 lumens @ 480p but is intended for the ipod crowd. The actual light engine is only the tip of the projector, the remainder of the projector is the battery. Motorola is planning on integrating the SHOW into cellphones. Rumor is that Microvision is working on higher resolution, but if/when that will make it to market is uncertain. All we can hope for is mass market adoption for the Show, and maybe this will encourage Microvision to enter the home theater projector market. If this mini laser projector comes to market they are saying less than $300 retail by end of 2008.

I'm still not seeing where I can get a mount kit to equip the sharks with.

That PicoP is very cool. As Kal was saying above, I thought all the "laser" projectors were just using lasers as a light source for an LCoS or other similar imaging chip. But it looks like the PicoP is painting the image pixel-by-pixel, modulating the lasers on each pixel, so yes, they should be capable of essentially infinite contrast. And zero optics (no lenses, etc) to mess up the contrast ratio. Just a little mirror scanning the image. I'm amazed they can get that so reliable and cheap.
Pretty cool how you don't even have to focus it. Just shine it on a wall, any wall, any distance. Very cool.
