Should Businesses Buy a Projector or an LCD Display?

With the price of large (>32”) LCD displays decreasing rapidly and new functionalities being added to LCD displays, 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 judgement.

Product Life: 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.

Price Considerations: A basic projector can be found for INR 25,000. However, if the projector is going to be used for video conferencing or board room presentation, a high resolution, good contrast ratio and saturated colour projector would be required. The cost of such a projector is close to INR 1 lakh. Thereafter, you need to factor in the prices of projector bulb and projection screens. A typical projector bulb needs to be replaced almost every year or two with bulbs costing Rs 20,000+ per bulb. We have added these costs over a five-year period to compare a projector vs. an LCD (see chart below). With 46” LCD TV or display costing around Rs 135,000 – Rs 150,000 and dropping, price becomes less of an issue when considering whether to buy a Projector or LCD display

Figure: Total Cost of Ownership Comparison for Projector vs. LCD Display

Basic Device capital cost for projector is INR 70,000 and that of an LCD display is INR 150,000, Projector Screen Capital Cost (Wall Mount Screens INR 5-15K) is INR 10,000, Consumable cost of the projector is 20,000 x 3 = INR 60,000, Consumable life of a projector is 2,000hrs and that of an LCD display is 60,000hrs and the Cost of Ownership of a projector is Rs.140, 000/- and Rs.150, 000/- for an LCD display.

Assume: 5years of usage @ 5hrs a day ~ 6600hrs of use. This translates to 4 lamps in 5 years requiring the customer to buy 3 lamps in addition to 1 supplied with machine.

What is clear from the above figure is that a Full High Definition 46” LCD Display is, at best, only marginally costlier than a XGA Projector of ~2500AL. Additional costs of low screen installation costs and lower device loss costs are purely additional.

Picture Quality: Projectors such as a DLP or LCD projector use glass panels to combine red, green and blue colours to create the image. When sitting close to screen, the viewer can see the different colours 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.

Rather, projectors cannot compare with the picture quality for an LCD display. The vividness of the colours, the contrast ratio, the colour saturation and image sharpness are much better for an LCD display than a projector. When viewing a projector image, especially in ambient light, the viewer has to dim the lights or close the curtains unless the business has purchased an even more costly higher lumen projector. Not true with LCD displays, as the brightness and colour quality are much better.

Viewing angles used to be an issue with LCD displays but this issue is no longer true. Most LCD displays can be viewed from up to 176 degrees.

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 warranty against such issues.

Screen Size: 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.

Portability: 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.

Power Consumption: 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.

Connectivity: Most LCD displays have more 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.

Other Value-Add Features: New features are appearing in LCD 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.

Where can I buy a four lcd display clock?

I saw a clock which called four side lcd display clock in tradekey. It’s cute and my girlfriend like it very much.i can’t find it in ebay and am wondering if it exist in USA. Can anybody help?i really want to buy one. you can have a look at the clock in the web site: http://www.tradekey.com/selloffer_view/id/704017.htm

Haha…I saw the clock, it’s really interesting. I think some seller will import it in bulk after they saw your post.,then you can buy from them. Since trakey is for B2B,if you really want to buy one immediately, you can contact that exporter in tradekey and ask him for a sample and you pay for it also the freight.i think he will agree. But the freight is expensive.
