BENEFITS OF PROJECTORS

Projectors  have become commonly used device for offices, schools, presentations and more. They help in projecting high-quality images, videos, and slides on a biggerr screen. They are usually used in seminars. And, people often use them in homes for watching movies and hosting events with family. Projectors also help set high-quality video presentations before a mass audience.

The use of a projector mainly depends on the type of projector you use. For example, an overhead projector is used in business meetings, churches, classrooms, and churches. Similarly, slide projectors are mainly used for viewing photos and business presentations. Nowadays, video projectors are used in homes for watching movies on a larger screen. They can be connected with a TV, computer, Wi-Fi, or satellite box. There are numerous types of video projectors available in the market. For Enquires Visit:

Some  projectors are widely used for projecting HD television and playing movies. It can also be used for livening up a party by projecting amazing light effects on the stage or dance floor.

These days, an engineering projector is widely used by engineers, architects, and people involved in real estate businesses to view the construction plan or blueprint. They are also used for showcasing multiple advertisements and commercials on larger screens.

                                                                       CATEGORIES  OF PROJECTORS:


  • Digital Light Processing DLP: projectors contain an array of microscopic mirrors that tilt either toward the light source in the projector or away from it to create a light or dark pixel on the projection screen.

   The technology takes advantage of a perception called persistence of vision. Our eyes see relatively slowly. Moreover, the image of what we see lingers for some time. The DLP engine will flash the red portion of the image on the screen and between 1/60th and 1/240th of a second later will flash the green portion.Then blue, then back to red. In that short time frame, the red does not entirely fade away— at least in our eyes. When the green and blue portions flash, we see it as one color.

The disadvantageous aspect  is that some people have faster vision than others and can see each color individually. This is known as the multicoloured  effect. This is less of a problem now than it used to be as companies have sped up the rotation of the wheel to reduce the effect..

Boasting high Contrast ratios, ( upto1,500,000:1) DLP  technology delivers crisp, sharp whites and deep dark blacks producing 3D-like images that almost pop out of the screen.

Well-Known for long term reliability:

DLP technology is also renowned for its quality and long term reliability. Today, lifetime estimates for a DLP chip exceed 100,000 operating hours and more than 1 trillion mirror cycles. DLP technology is robust mechanically, electrically and environmentally.


DLP  Video wall is an ideal choice of many control room operators for their reliability, performance and long life in mission-critical applications like traffic control rooms, Power control rooms, Utility control centres, and disaster management centres.

Single-chip DLP offers the sharpest image you can usually find in a home projector. While all other types of projectors use three chips, also called “panels” (one for each primary color in an image), DLP projectors use a single chip. This means there are no panel alignment problems and the image is razor sharp. To accomplish this, a single-chip DLP projector uses a color wheel that rotates between the three primary colors. For many people this is fine, but some users might notice a “rainbow effect.” A rainbow effect breaks up the image into separate red, green, and blue images. For example, if there is white text on the screen and you move your head, you will see the same text in red, blue, and green. Some people never see these multiple images; but others do, so be sure to watch a movie on a DLP projector before buying one.

Three-chip DLP projectors do not suffer from this rainbow effect because they use a DLP chip for each color instead of a color wheel. The drawback is that getting all three panels in perfect alignment is harder and therefore requires a more complex and expensive design. Three-chip DLP projectors are often what movie theaters use. They are capable of producing bigger, brighter images than other projector technologies. They are also available in resolutions up to 4K, and have the ability to produce more colors than other types of projectors.

DLP projectors are usually the best for watching 3D movies. Since the mirrors turn completely on or off, 3D is free of the faint double images that LCD and LCoS projectors can sometimes produce. This instant on/off ability also makes them a good choice for sports with its fast action. Video games are another good area for DLP projectors because of their fast response and lower lag times.



Liquid Crystal on Silicon Like an LCD projector, LCoS projectors: shine light through a panel to create an image. Unlike LCD projectors which shine a light through a single LCD panel, the light from a LCoS projector reflects off three individual LCoS panels, which are then combined to produce the image. By reflecting the light off the panel instead of shining light through it, LCoS projectors offer the darkest black levels and contrast ratios of any technology. Better black levels make the film more immersive when viewed in a dark room. Plus, the letterbox bars on CinemaScope-format movies disappear and shadows look much better. Darker blacks also help increase the contrast ratio, which gives the image more pop. However, LCoS projectors usually cannot offer the same brightness levels of DLP and LCD projectors (which makes these two types of projectors ideal for rooms where there is a high degree of ambient light, or if you simply like to watch video with the lights on).


 LCoS  projectors usually offer lower levels of light output, they often don’t work well when paired with gigantic screens. For screens measuring less than 130 inches diagonally, they are able to produce enough light to fill the entire screen; anything larger and it’s best to use a brighter projector. They also exhibit more image blurring on fast-moving images than DLP and some LCD projectors. For film, this isn’t an issue, but it makes them problematic when watching sports and 3D content. For watching films in a dedicated room, they offer the best blacks and contrast ratios currently available. 


LCD (Liquid Crystal Display)

LCD projectors fall right in the middle of DLP and LCoS projectors. They aren’t as bright as DLP projectors, but they are usually brighter than a LCoS projector. They don’t produce the deep blacks that LCoS projectors do, but they are better at it than DLP projectors. Motion is not as sharp and fast as what a DLP projector can produce, but motion from an LCD projector trumps that of a LCoS projector. 3D images produced by an LCD projector can be less accurate (faint double images) than 3D images produced by a DLP projector, but an LCD projector can outperform a LCoS projector due to its ability to produce bright images. 

LCD projectors are affordable, starting at the same price as a single-chip DLP projector. At the high-end, an LCD projectors costs just a few thousand naira. Shop for everything Smartphones and Laptop Accessories as you enjoy prompt services and quick delivery.
