In collaboration environments there is often the need to display different types of content. Selecting the correct display plays an integral role in the effectiveness of a collaboration environment as the wrong type of display can provide a poor user experience. For example, if the display is too small for the room, participants will have a difficult time seeing the content.

The two main types of displays are flat panel displays and projection systems and there are several factors to consider when selecting a display. This includes the size of the room, the application and type of content being displayed, room aesthetics (amount and type of lighting), the budget and overall user expectations.

The size of the room has a direct correlation to the size of the display; larger spaces will need a larger display while smaller spaces can used a smaller display. Flat panel display sizes typically range anywhere from 42” to 90” diagonal but can go to 103” while projector screen sizes typically range from 119″-133″ diagonal and up.

Projection Systems:
Projectors are great for sharing text, spreadsheets or presentations as projectors can provide a larger image at a lower price point. Projection screens can also be hidden in the ceiling when they are not in use. However, projectors require low-lit or dim spaces as room light from bulbs and windows can wash out the image on the screen. Projection systems are either rear project or front projection systems.

In rear projection implementation, a projector is placed in a projection room and the image is bounced off a series of mirrors on the projection screen. This allows the projector to remain hidden, eliminating any projector noise and is also less sensitive to ambient lighting. However, collaboration rooms must be large enough to accommodate a projection room. In front projection implementation, the projector is hung from the ceiling or hidden in a drop down platform and the image is projected directly onto the front of the screen. While this setup eliminates the need for a control room, it is more susceptible to ambient light and does not hide projector noise.

Flat Panel Displays:
Flat panel displays are typically used for video conferencing as well as presentations. Flat screens offer a clear, vivid picture which is ideal for high resolution images. They are not as susceptible to ambient light; however, for an optimal experience organizations may still want to cover windows if there is a substantial amount of direct natural light coming into the room to prevent a glare. There are three types of flat panel displays including plasma, liquid crystal display (LCD) and light emitting diode (LED).

Plasma displays use gas to excite light photons which produce color on the screen. They provide the highest and most accurate representation of color and a consistent brightness to the image which can be important when displaying images or other content. However, plasmas are typically heavier, not as bright and consume more energy than other types of displays.

LCD displays use pixels that contain three colors (red, green and blue) plus a backlight. The liquid crystals, when energized, block certain colors from showing and produce the desired color. LCD displays are lighter and consumer less energy than plasmas and are typically at a lower price point.

LED displays are similar to LCD displays and use a cluster of red, green and blue diodes that are driven together for form a full color pixel. LED displays are the lightest and most energy efficient of flat panel displays. They are also brighter and provide a more accurate color than LCD; however, they are at the highest price point.

When faced with a display decision, it is important to understand how and where the equipment will be used along with the budget requirements. While a 103” plasma display might provide a lifelike experience; it is not the most affordable solution. An organization must consider the application and types of content being displayed to determine the right type of display technology.
