With the price of large (>32″) LCD TVs decreasing rapidly and new functionalities being added to LCD TVs, does it still make sense for businesses to buy a projector vs. an LCD display? Some of the variables to consider when evaluating this question are product quality, price, picture quality, screen size and other such considerations. We discuss these and other factors from a typical business organization perspective. Read other articles and make your informed judgment.
LCD TVs or displays typically have a backlight life of 30,000 to 60,000 hours (ie, if you have the display on for ~6 hours every day, the backlight will last for 16 years). Even then the backlight can be replaced in most LCD displays. A projector bulb typically has a life of 2,000 hours.
Projectors such as a DLP or LCD projector use glass panels to combine red, green and blue colors to create the image. When sitting close to the screen, the viewer can see the different colors at the borders of an image, aptly described as the rainbow effect. The rainbow effect takes away from the image quality and can give headaches. High-end projectors have been able to reduce the rainbow effect, however, the problem still remains and these high-end projectors cost more. LCD TV or LCD displays do not have rainbow effect issues and the quality of the picture is good at close range.
Dead or Stuck Pixels
Projectors can suffer from dead pixels and LCD displays can suffer from stuck pixels. Both dead pixels and stuck pixels result in white spots in the projected image. However, the manufacturers of both technologies have worked hard to minimize such issues and in most cases, they provide a warranty against such issues.
A common thought is that screen size is not an issue for most projectors as the thinking is that the projector image can be made larger by moving the projector away from the screen. This is not true as the image quality deteriorates as the image becomes larger. With projectors, most buyers opt for maximum optimized projector image sizes from 76-inches to 120-inches and the actual working normal projection image used is much smaller. Today, if businesses need a large LCD display in the maximum projector image size, a wide variety of competitive LCD displays can be found in this range.
Projectors are easy to carry and move around. For a business, this could be a value-add or a drawback. LCD displays are durable and can be moved however they are not as light as projectors.
Projector power consumption varies more from unit to unit, with brighter conference projectors requiring more power than smaller portable projectors. It is hard to compare the two technologies on this performance parameter.
Most LCD displays have number and different types of ports than projectors. As a result, more types of devices can be connected to an LCD display than a projector.
New features are appearing in LED displays that could be quite valuable for businesses. For example, touch screen features on LCD displays allow for LCD displays to be used as digital whiteboards where the data written on the display can easily get captured electronically in a text document.
