What is the difference between flat panel displays (LCDs and LEDs) that I find online and the models that JSA uses?

Most flat panel displays that you will find online are meant for personal consumers. When these are used in an organizational setting, the warranty is usually limited to 90-days and, in some cases, may be voided altogether.

In contrast, the commercial flat panel displays that we sell and use in our systems come with a 3-year warranty. These displays also feature capabilities that are often not found on personal consumer models. For instance, RS-232 ports enable advanced communication with an audiovisual control system.

In addition, commercial displays are often more rugged. First, they are suitable for extended usage such as 24/7 applications. Also, they may provide a longer overall service life. Lastly, they are often more resistant to temperature extremes, vibration, dust, and other environmental challenges.

What are the advantages of a projector that uses a laser light source?

Laser light sources are one of the newest trends in projection technology. Projectors using this type of light source offer a number of advantages when compared to projectors using traditional light sources, such as halogen bulbs.

  Lamped Laser
Total Cost of Ownership At a cost of $400 to $800 per lamp, you can expect to spend between $2,000 and $4,000 over the 5 to 10 year lifespan of your projector. This does not even account for expenses associated with down time and lamp/filter installation. There are no lamps or other consumables to replace in a laser projector. You get uninterrupted productivity: from 10,000 hours up to nearly 90,000 hours depending on the model and operating mode.
Energy Usage When they reach full power, lamp temperatures can exceed those of a typical, residential oven. To protect the lamp and projector from damage, fans must run at high speed to exhaust the heated air which can lead to a loud projector. In addition, the heat is a waste product of the electricity powering your lamp: it’s basically your electric payment vanishing into thin air. Since there are no lamps to warm up, the projector turns on and reaches full brightness almost instantly. Because of the lower amount of heat, fans can be smaller and quieter and energy usage is lessened.
Color Reproduction The color and intensity of the light being emitted by the lamp changes over time. Also, no two lamps emit the same color; this can have a noticeable effect when projectors are installed in a side-by-side application. The difference can be even greater if lamps are at different stages of their useful lives. Lastly, the heat from the lamp cooks DLP and LCD chips which diminishes the projector’s ability to output vivid colors. While there is some gradual change in color output of a laser projector, it is much less since the chips are under much less stress. These projectors are particularly well-suited for side-by-side applications since there is virtually no variation in color between units. Light output is constant over the life of the projector.
  • Suitable for 24/7 Applications—Up to 10 years of continuous operation. That’s 87,600 hours!
  • Dust Resistant—Decreases component failure rates for improved reliability.
  • Adaptive Brightness and Contrast—Automatic adjustments as lighting conditions change.
  • No Hazardous Chemicals—Lamp modules may contain mercury, lead, and halogenated flame-retarding materials.
