Ought to Businesses Buy a Projector Or an LCD Display?

With all the price of large (> 32″) FLAT SCREEN displays decreasing rapidly and new functionalities being added to LCD shows, does it still make sense for companies to buy a projector vs . an Lcd-display?

Some of the variables to consider when analyzing this question are product quality, price, picture quality, screen size and other such considerations. We discuss these and other factors from a typical business company 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 upon for ~6 hours every day, the backlight will last for 16 years). Even then the backlight can be changed in most LCD displays. A projected bulb typically has a life associated with 2, 000 hours.

Price Factors: 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 over loaded colour projector would be required. The cost of such a projector is close to INR 1 lakh. Thereafter, you need to element in the prices of projector bulb and projection screens. A typical projector bulb needs to be replaced almost every year or two along with bulbs costing Rs 20, 000+ per bulb. We have added these types of costs over a five-year period to compare a projector vs . an FLAT SCREEN (see chart below). With 46″ LCD TV or display costing about Rs 135, 000 – Rs 150, 000 and dropping, cost becomes less of an issue when it comes to whether to buy a Projector or LCD display

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

Fundamental Device capital cost for projector is INR 70, 000 and that of an LCD display is INR a hundred and fifty, 000, Projector Screen Capital Cost (Wall Mount Screens INR 5-15K) is INR 10, 000, Consumable cost of the projector is 20, 500 x 3 = INR sixty, 000, Consumable life of a projected is 2, 000hrs and that of the LCD display is 60, 000hrs and the Cost of Ownership of a projector is definitely Rs. 140, 000/- and Rs. 150, 000/- for an LCD display.

Suppose: 5years of usage @ 5hrs a day ~ 6600hrs of use.

This translates to 4 lamps in five years requiring the customer to buy 3 or more lamps in addition to 1 supplied with device.

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

Picture Quality: Projectors such as a DLP or even LCD projector use glass sections to combine red, green and blue colours to create the image. When sitting close to screen, the viewer can easily 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 provide headaches. High-end projectors have been capable of 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 as well as the quality of the picture is good with close range.

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

Viewing angles used to be a problem with LCD displays but this problem is no longer true. Most LCD shows can be viewed from up to 176 levels.

Dead or Stuck Pixels Projectors can suffer from dead pixels and LCD displays can suffer from stuck pixels. Both dead pixels plus stuck pixels result in white areas in the projected image. However , the manufacturers of both technologies have worked difficult to minimize such issues and in most cases they provide warranty against such problems.

Screen Size: A common thought is that screen-size is not an issue for most projectors because the thinking is that the projector image could be made larger by moving the particular projector away from the screen. This is simply not true as the image quality deteriorates as the image becomes larger. Along with projectors, most buyers opt for maximum optimized projector image sizes through 76-inches to 120-inches and the real working normal projection image utilized is much smaller. Today, if businesses need a large LCD display in the optimum projector image size, a wide variety of aggressive LCD displays can be found in this variety.

Portability: Projectors are easy to carry plus move around. For a business this could be the value-add or a drawback. LCD displays are durable and can be moved however they are not as light since projectors.

Power Consumption: Projector power consumption varies more from unit to unit, with brighter conference projectors requiring more power than smaller sized portable projectors. It is hard to compare the two technologies on this performance parameter.

Connectivity: Most LCD displays convey 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.
