With businesses becoming more visually oriented, seminars, sales projection presentations, client presentations etc. are an inherent part of most enterprises. Gamers, restaurateurs, event planners, malls, sports fanatics, movie buffs, campers, and marketing companies consider projectors as the most useful assets for a high-quality visual experience to present to large groups.
There are six factors that predominantly influence how a projector presentation solution works which is called the projector technology and which projector one must choose for their individual requirements:
Sources of Light
The source of lighting for a projector is influenced by three options namely, lamp, laser, and Light Emitting Diodes (LED).
With the lamp technology, the bulb of the projector can last for up to 4000 hours depending on the frequency of usage and more than that on ECO mode. The light output from the projector is bright, while the cost is cheaper than the other two variants.
The Laser technology is an energy-saving option that does not require the bulb to be replaced, which is a great advantage during long meetings. Brightness in on-point and the color range is wider, the contrast imaging capabilities are also better than other technologies.
In terms of duration, LED projectors cover above 20,000 hours with better color control, quieter operation, without the need for a coolant. The only downside is that this technology-inspired projector comes with a heavy price tag.
Measured in lumens, brightness affects the quality of the images and videos with increasing distance. The white light output and the color light output affect the detail and the vibrancy of white light and color lights respectively on the projecting surface. For business presentations, a high lumen rating is always preferred to avoid dull or dark renditions. The idea is to display greatly illuminated images and videos in a dark or well-lit room.
The ratio of difference between the darkest and the brightest areas of an image. A high-contrast ratio-based projector will give the images more depth and dimension while emphasizing on shadowy details and black levels. Home theatre systems need a higher contrast ratio, while business projectors do not demand much of it because of the difference in the environmental lighting requirements.
The native resolution of a projector determines the number of pixels the projector is capable of displaying. More detailing requires more pixels display on a surface, just like a digital camera. Resolutions are available from 480p to 1080p for low resolution to High Definition resolutions. 4k resolution is fit for Ultra HD imaging.
The throw ratio determines the width of the image based on the distance at which the projection is done. A short throw projector is best suited for smaller rooms while a long throw projector works for longer or wider rooms. The maximum and minimum screen sizes and projection distances will have to be calculated for different projectors in order to select the best one for a given space.
Lens Zoom and Lens Shift
Lens zoom is the feature of the projector that provides convenience. When the screen size and the projector placement is out of the operator’s control, the lens zoom helps adjust the projection of the image dynamically. More sophisticated projectors for business meetings must have this feature. The Lens shift helps to adjust the angle of the lens to remove any projection distortions.
Types of Projectors
Based on the above factors, the types of projectors available in the market can be divided into three categories:
Digital Light Processing Projectors
This type of projector has great color accuracy and sharp image quality. Mostly light-weight and compact, it used for home screening from a DVD, Blu-Ray player, and HDTV sources. It can take faster animated projections and display them accurately and effectively. Deeper blacks are emphasized on screen with more color contrast. A 3-chip DLP provides higher image sharpness and display quality.
Liquid Crystal Display Projectors
LCD projectors are great for well-lit rooms. The color contrast and brightness attributes are impressive with sharper image detailing for business presentations. Quality 3D imaging sans ghosting is a boon for corporate training and meetings. The energy efficiency and lesser projection noise are great for official presentations while the 3-chip LCD version is supreme quality-wise.
Liquid Crystal on Silicone
A hybrid of the first two types, LCoS technology is used for very high-end models. Brighter display, smooth image rendition, and great color saturation and impact are the attributes of LCoS.
Taking the above points into consideration, the top 3 projectors that have established themselves in the market are given below.
