With all the price of large (> 32″) FLAT SCREEN displays decreasing rapidly and brand 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 analyzing this question are product quality, price, picture quality, screen size and other this kind of considerations. We discuss these along with other factors from a typical business corporation perspective. Read other articles plus make your informed judgement.
Support life: LCD TVs or displays routinely have a backlight life of thirty, 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 replaced in most LCD displays. A projector bulb typically has a life associated with 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 quality, 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 aspect 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 in order to 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 considering whether to buy a Projector or Lcd-display
Figure: Total Cost of Ownership Assessment for Projector vs . LCD Display
Simple 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 usually INR 10, 000, Consumable cost of the projector is 20, 500 x 3 = INR 60, 000, Consumable life of a projected is 2, 000hrs and that of the LCD display is 60, 000hrs as well as the Cost of Ownership of a projector is usually Rs.

140, 000/- and Rs. 150, 000/- for an LCD display.
Presume: 5years of usage @ 5hrs a day ~ 6600hrs of use. This particular translates to 4 lamps in 5 years requiring the customer to buy several lamps in addition to 1 supplied with machine.
What is clear from the above number 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 extra.
Picture Quality: Projectors such as a DLP or even LCD projector use glass panels to combine red, green and glowing blue colours to create the image. When seated 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 removes from the image quality and can give headaches. High-end projectors have been capable to reduce the rainbow effect, however the problem still remains and these high-end projectors cost more. LCD TV or LCD shows do not have rainbow effect issues as well as the quality of the picture is good in 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 plus image sharpness are much better for an LCD display than a projector. When seeing a projector image, especially in background light, the viewer has to dim the lights or close the particular curtains unless the business has bought an even more costly higher lumen projector. Not true with LCD displays, since the brightness and colour quality are 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 spots in the projected image. However , the manufacturers of both technologies have worked difficult to minimize such issues and in most all cases they provide warranty against such problems.
Screen Size: A common thought is that screen-size is not an issue for most projectors since 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 dips 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 utilized is much smaller. Today, if businesses need a large LCD display in the optimum projector image size, a wide variety of competing LCD displays can be found in this variety.
Portability: Projectors are easy to carry and move around. For a business this could be the value-add or a drawback. LCD displays are durable and can be transferred however they are not as light since projectors.
Power Consumption: Projector power consumption varies more from device to unit, with brighter conference projectors requiring more power than smaller portable projectors. It is hard to evaluate the two technologies on this performance variable.
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.
