Should Businesses Buy a Projector or an LCD Display?

No comments · Posted by admin in Pocket Projectors

With the price of large (>32â) 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 spectacle?

Some of the variables to consider when evaluating this question are manufactured goods quality, price, depiction quality, screen size and other such considerations. We chat about these and other factors from a typical affair establishment perspective. Read other articles and make your informed judgement.

Manufactured goods Life: LCD TVs or displays typically have a backlight life of 30,000 to 60,000 hours (ie, if you have the spectacle 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. Even if, if the projector is going to be used for video conferencing or board room presentation, a high pledge, excellent contrast ratio and soaked colour projector would be required. The cost of such a projector is close to INR 1 lakh. Thereafter, you need to thing in the prices of projector bulb and projection screens. A typical projector bulb needs to be replaced nearly every year or two with bulbs costing Rs 20,000+ per bulb. We have added these costs over a five-year period to equate a projector vs. an LCD (see chart below). With 46â LCD TV or spectacle costing nearly Rs 135,000 â Rs 150,000 and dropping, price becomes less of an issue when considering whether to buy a Projector or LCD spectacle

Map: Total Cost of Ownership Evaluation for Projector vs. LCD Spectacle

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

Take upon yourself: 5years of usage @ 5hrs a day ~ 6600hrs of use. This translates to 4 lamps in 5 years requiring the consumer to buy 3 lamps in addendum to 1 supplied with apparatus.

What is clear from the above map is that a Full High Classification 46â LCD Spectacle is, at best, only marginally costlier than a XGA Projector of ~2500AL. Bonus costs of low screen installation costs and lower device loss costs are purely bonus.

Depiction Quality: Projectors such as a DLP or LCD projector use glass panels to combine red, green and blue colours to start the image. When sitting close to screen, the viewer can see the different colours at the limits of an image, aptly described as the rainbow look. The rainbow look takes away from the image quality and can give headaches. High-end projectors have been able to reduce the rainbow look, even if the problem still remains and these high-end projectors cost more. LCD TV or LCD displays do not have rainbow look issues and the quality of the depiction is excellent at close range.

Very, projectors cannot equate with the depiction quality for an LCD spectacle. The vividness of the colours, the contrast ratio, the colour saturation and image serration are much better for an LCD spectacle than a projector. When viewing a projector image, especially in ambient light, the viewer has to dim the illumination or close the curtains except the affair has bought an even more costly privileged lumen projector. Not right 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 right. 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. Even if, the manufacturers of both technologies have worked hard to minimize such issues and in most cases they grant warranty against such issues.

Screen Size: A run of the mill thought is that screen size is not an issue for most projectors as the thought is that the projector image can be made larger by moving the projector away from the screen. This is not right 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 effective habitual projection image used is much less vital. Today, if businesses need a large LCD spectacle in the maximum projector image size, a wide variety of competitive LCD displays can be found in this range.

Portability: Projectors are simple to carry and go nearly. For a affair this could be a value-add or a drawback. LCD displays are durable and can be went even if they are not as light as projectors.

Power Employment: Projector power employment varies more from unit to unit, with brighter talks projectors requiring more power than less vital portable projectors. It is hard to equate the two technologies on this performance parameter.

Connectivity: Most LCD displays have more digit and different types of ports than projectors. As a result more types of diplomacy can be connected to an LCD spectacle than a projector.

Other Value-Add Features: New features are appearing in LCD displays that could be quite vital for businesses. For model, touch screen features on LCD displays allow for LCD displays to be used as digital whiteboards where the data on paper on the spectacle can straightforwardly get captured electronically in a text paper.
