Like many things, size is a matter of relativity. Going back into our "way-way back machine", video projection meant Eidophors, huge and complex beats that consumed enough power to keep a small-sized city going for a week, required one or two trained operators to watch over them, and were often cranky on the best of days. When GE unveiled their Taleria projectors, you thought you really had something compact. Power consumption was less, only one operator was required with less training, and two or three strong guys could actually lift one, as opposed to the forklift needed for an Eidophor.

Things have certainly changed since those days. Large venue projectors may not be all that smaller (in volume) than the Talerias, but their resolution, reliability and brightness are certainly greater, while their price and operator and maintenance requirements are certainly less. CRT projectors are more or less long gone, with DLP, LCD, and LCoS units found in applications from cinema to classrooms, sports bars, to houses of worship, homes to training centers. They're smaller, lighter, more reliable, and maintenance-free except for the occasional bulb replacement and higher in resolution. Projectors are sold almost everywhere, from "professional" sources to the local office supply store. You not only place them on desktops or conference tables, but they are small and light enough to fit in your clients' briefcases, or thrown (GENTLY) on the back seat when you need one to bring along to a client presentation.

That's all well and good, and certainly evidence of the forward march or technology. However, the next big technology wave in projection that you need to be prepared for is one that may smash your notion of what a projector is and does, in the same way that Taleria was a leap ahead of its larger predecessors. The category is known as "pico projectors", and with comparative size as our starting point, they are smaller than the remote controls us oldsters used to operate oil-pan based light valve projectors.

While not literally giving true definition to "pico", which is defined as "one-trillionth", pico projectors will, if they achieve their goals, fit inside your average remote control, or, more to the point, a cell phone.

Tiny Uprising
We first reported on developments in these compact units after the first major wave of showing them at SID's Display Week last summer. At that time things were still in prototype form with umbilical cords connecting the demo units to larger cases containing the driver electronics and power sources. As we head into the big 2008 trade show cycle, and with CES just behind us and NAB and InfoComm in front, pico projectors are closer to becoming a reality. If they don't appear in the next few months, barring any major barriers to technology that we've already seen demonstrated, at least one manufacturer should have them no later than this time next year.

As had always been the case with projectors, the goal is to get the largest, brightest image with the highest resolution from the smallest possible form factor, using the least power consumption at the lowest cost. Over time, many different technologies have been used to strive for those goals, and naturally the same goes for pico projectors. The light source may be a laser, LED, or a proprietary technology. The imager may be a miniature version of Texas Instruments' DLP system, or another proprietary micro-mirror/MEMS imager such as the technology from Washington-based Microvision.

Alternatively, LCD or LCoS based engines are also in the running, from companies such as 3M, or hybrid LED/microlens/modulated systems from Israel's Explay. (Incidentally, Explay calls their product concept a "nano-projector". As nano is one-billionth, you can definitely see that size really is relative here.)

The best way to picture these units is to think of a cell phone, large remote control, portable media player, or digital still camera that, rather than having the standard LCD or OLED display, has a lens at the top or side. Turn the "projector" on, and depending on the unit and technology, you can shoot a picture the size of a standard sheet of paper at a very short throw distance. Change things a bit and make it a dedicated projector, and, again, depending on throw distance, optics, ambient lighting, and technology, some of the manufacturers are claiming image sizes up to 100 inches diagonal with WVGA or better resolution.

That's the brief on what they are and a little of how they do it and what they can do, but as a systems integrator, the question for you now becomes where do you use them, what would you use them for, and what are the current technologies and products they might displace?

Big Possibilities
Depending on cost and the actual performance of these units, the ability to place what will likely be a tablet-sized picture almost anywhere without worrying about power consumption or mounting problems is very intriguing. Imagine being able to equip medical professionals with handheld, battery-powered viewers for test results or images that they can retrieve via a wireless link and then shoot on the wall to share with a patient. How about a portable "viewer" used in conjunction with a pin-type camera to create an instant image magnifier for menus, patient instructions, or anything else in small type that might be difficult for a vision-impaired person to read, helping your clients to use technology to stay on the right side of the Americans with Disabilities Act?

While small-sized LCD displays have begun to take root as an electronic replacement for product information cards at trade shows, pico projectors could provide new ways to display that type of data. Since the presumption here is that the "screen" may often be a white wall or sheet of paper, the benefit of a pico projector is that someone can throw it in their pocket and shine it almost anywhere, getting the same (or larger) picture size as a small LCD without worrying about rigid sizes, cracked screens, or operation in low or high temperature extremes.

Here is where dreaming up pico projector applications begins to make them a potentially disruptive technology. On the spot, collaborative decision-making where having everyone view the same image in a school, training session, retreat center, or mobile command post? Think outside the box here and you may find it is something that would otherwise be a risky, expensive, hard-to-install, or perhaps just downright silly application.

Where Are They?
It all sounds nice, but as mentioned at the top of this column, product pricing and availability is still tentative. Some technology developers may prefer to simply license their IP to OEM/ODM integrators. That's what is already rumored to have happened with some companies, such as reports of iPhone's manufacturer already licensing pico projector technology. As it has done with its DLP technology for standard projectors, it is unlikely that TI will brand its own products, preferring to enable, but not make them. The same goes for Colorado-based Displaytech, Israel-based TeraOp, and Dallas-based Syndiant, all companies with imaging technology plays. Others, such as Microvision and Explay, seem more likely to try to crack the market themselves as well as license the tiny projection engines. Motorola could go either way, using in-house technology from Symbol Technologies, which it purchased in 2006, or with licensed technology or engines. With all of these players, there are rumors and press releases, but as of yet, no products you can buy today.

At the end of the day, this isn't something you can promise to a client right now. Indeed, as with many "future technologies that are just around the corner", this could end up being another idea that never becomes technically practical for production or even economically viable. On the other hand, the appeal of a projector you can pack in a cell phone or camera is too alluring for scientists and engineers to give up on. Thus, when you have a spare moment to think about how you'd incorporate displays in new ways in some future job, perhaps a year or more down the road, think about pico projectors as something you may end up using sooner than you might think. At the very least, when-or if-they do appear, you can now say you were warned!
