The major advantages of a laser display are superior picture quality and longer life. Our (LLE) Laser Light Engine® produces more natural color, a greater range of colors, and higher resolution. It offers long-term stability of color purity and brightness, absence of motion or decoding artifacts, low power consumption, environmental compliance, lighter weight, wide depth of field, ability to maintain focus when projected on irregular surfaces, and wide angle of view.

All color video requires an RGB color source. Other projection systems start with white light and separate out the three primary colors (red, green and blue) through the use of filters. The difficulties in separating a pure color from white light inherently reduces color accuracy. A laser projector has the advantage of starting with pure, saturated red, green, and blue light, each of a specified wavelength.

Unlike chip-based technologies [e.g., liquid crystal displays (LCDs), plasma display panels, digital light processors (DLPs), laser projection systems do not require internal processors, allowing them to image fast-moving subjects without ghosting. Laser images are not limited by the purity of phosphors contained in CRTs or ion exchange gases, as plasma devices are. Because each laser emits fully saturated color, the video images they produce are lifelike in their color reproduction. LightRush has patented, for projection applications, a broad range of colors for each laser. By using wavelengths contained within its patent, the LightRush projector can produce an extremely large color space (gamut). The CIE chromaticity diagram below shows the gamut of visible light. Portions outlined indicate color gamuts for various imaging media.

Projector lamps produce wavelengths that generate heat. They require warm-up before stabilizing. Over time colors may drift. Variations in lamp filaments compound the problem.

Brightness and resolution are independent in laser systems. With other video display technologies, an increase in brightness washes out the colors and reduces contrast. On CRTs, for example, increasing the brightness results in decreased resolution, referred to as 'blooming.' LCD systems suffer color shift and other performance problems due to the heat generated by their filament light source.

Increasing the power output of the lasers does not reduce the system's resolution capability. Conversely, increasing the resolution of the system does not decrease overall image brightness. Increased brightness does not dilute laser color.

The LightRush® laser system is environmentally friendly. It does not contain phosphorous, lead shielding, or mercury. It doesn't generate harmful electromagnetic radiation. It is energy efficient, consuming less power than any other display technology capable of similar size images.

Solid-state lasers are long-life components making our LLE® a potentially maintenance-free projector. There are no projector lamps for the user to replace at a cost ranging from $200 to $1000 or more for every 1,000 to 2,000 hours of use. Even though some manufacturers claim over 2,000 hours of use, such bulbs typically suffer significant loss of brightness before failure. LightRush®'s lasers suffer none of these shortcomings.

This provides a high-contrast, film-like picture, rather than a pixelized image. When viewed on large screens, images that are represented by discrete pixels can be very distracting (like looking through a screen door). CRTs, DLPs, LCDs, and plasma displays all have a fixed pixel layout whose grid produces spatial frequency beats when they are used in conjunction with a lenticular screen.

DLPs, LCDs and plasma displays all require image processing that can result in motion and decoding artifacts created by the spatial modulation methods evidenced by annoying effects within an image. LightRush®'s display requires no image processing that will result in image artifacts.
