Abstract
Micro-project and implimentationion is looked at as a bit of a holy grail for mobile devices. The ability to project and implimentation a decent-sized image from a tiny device solves the problem of tiny screen sizes on portable video and image players we're already seeing lots of in mobile phones and PDAs as well as standalone units. A reasonable micro project and implimentationor could transform the portable video experience from 'lean forward and squint' to 'sit back and watch,' making mobile visual content infinitely more sharable and social in the process - not to mention the obvious business applications.

Nano project and implimentationor
There are two types of conventional project and implimentationors: digital light processing (DLP) project and implimentationors and liquid crystal display (LCD) project and implimentationors. DLP project and implimentationors use a special optical semiconductor called a digital micro-mirror device (DMD). This chip, which was invented in 1987 by Texas Instruments, is a precise light switch that enables light to be modulated digitally via millions of microscopic mirrors. The mirrors are capable of switching on and off thousands of times per second and are used to create a picture comprised of millions of pixels.

LCD project and implimentationors use a number of small LCD panels (the same technology used for displays) through which light is passed. As the light passes through the LCD panels, individual pixels can be opened or closed to control the passage of light. This activity modulates the light and produces the image that is project and implimentationed onto the screen. Both DLP and LCD types use a conventional light source (a special, usually expensive light bulb). To make the project and implimentationor more powerful, more energy is required, translating to a larger device that produces more heat and thus requires active cooling (which again takes up space, requires energy, and has a tendency to break down). Although some improvements have been made in recent years, these problems put lower limits on the size of project and implimentationors based on conventional DLP/LCD technology.

It became apparent in recent years that there is a growing market base for a small, light, and relatively inexpensive project and implimentationor that could be carried along with a laptop, cellphone, or pocket PC to easily present pictures, movie clips, and presentations. Since, as mentioned above, heat and power consumption limitations plague existing DLP/LCD technology, a new technology was needed. Enter Explay, with a radically different way of project and implimentationing an image. Instead of using a conventional light source to produce a picture, it set out to develop a laser-based light source for its device. In a conventional project and implimentationor, only about 15% of the energy is ultimately transferred to the project and implimentationed image. (Most of the energy is lost as heat, which is why project and implimentationors are usually so hot to the touch and require active cooling.) Laser light is much more focused, allowing for a much more efficient way of producing an image. It also requires less energy and thus produces far less heat, eliminating the need for active cooling and so dramatically reducing the size of the project and implimentationor.
