Slipway To Success In The Presentations & Get Your Job Substance To A Higher Story

What’s in your mind when you hear the word ViewSonic? Yes, of course, you immediately think of CRT monitors, Projectors, plasma displays, HDTV technology, and others.

Indeed ViewSonic Corporation is a manufacturer and provider of visual technology, specifically CRT monitors, liquid crystal displays, projectors, plasma displays, HDTV technology, and mobile products, including Mini & All in One PCs and wireless monitors.

A video projector is a device that receives a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for conference room presentations, classroom training, home theatre and live events applications. Projectors are widely used in many schools and other educational settings, connected to an interactive whiteboard to interactively teach pupils.

A video projector, also known as a digital projector, may be built into a cabinet with a rear-projection screen (rear-projection television, or RPTV) to form a single unified display device, now popular for “home theater” applications.

General showing resolutions for a portable projector include SVGA (800×600 pixels), XGA (1024×768 pixels), 720p (1280×720 pixels), and 1080p (1920×1080 pixels).

The cost of a device is not only determined by its resolution, but also by its brightness. A projector with a higher light output (measured in lumens, symbol “lm”) is required for a larger screen or a room with a high amount of ambient light. A rating of 1500 to 2500 ANSI lumens or lower is suitable for smaller screens with controlled lighting or low ambient light. Between 2500 and 4000 lm is suitable for medium-sized screens with some ambient light or dimmed light. Over 4000 lm is appropriate for very large screens in a large room with no lighting control (for example, a conference room). Projected image size is important; because the total amount of light does not change, as size increases, brightness decreases. Image sizes are typically measured in linear terms, diagonally, obscuring the fact that larger images require much more light (proportional to the image area, not just the length of a side). Increasing the diagonal measure of the image by 25% reduces the image brightness by more than one-third (35%); an increase of 41% reduces brightness by half.

CRT projector using cathode ray tubes. This typically involves a blue, a green, and a red tube. This is the oldest system still in regular use, but falling out of favor largely because of the bulky cabinet. However, it does provide the largest screen size for a given cost. This also covers three tube home models, which, while bulky, can be moved (but then usually require complex picture adjustments to get the three images to line up correctly).
LCD projector using LCD light gates. This is the simplest system, making it one of the most common and affordable for home theaters and business use. Its most common problem is a visible “screen door” or pixelation effect, although recent advances have minimized this.
DLP projector using Texas Instruments’ DLP technology. This uses one, two, or three micro fabricated light valves called digital micro mirror devices (DMDs). The single- and double-DMD versions use rotating color wheels in time with the mirror refreshes to modulate color. The most vulgar problem with the single- or two-DMD varieties is a open “rainbow” which whatever people perceive when aflare their eyes. More recent projectors with higher speed (2x or 4x) and otherwise optimized color wheels have lessened this artifact. Systems with 3 DMDs never have this problem, as they display each primary color simultaneously.
LCOS projector using State crystal on element.
- D-ILA JVC’s Direct-drive Someone Illumine Amplifier based on LCOS discipline.
- SXRD Sony’s proprietary variant of LCOS technology.
LED projectors use one of the above mentioned technologies for image creation, with a difference that they use an array of Light Emitting Diodes as the light source, negating the need for lamp replacement.
Hybrid LED and Laser diode system developed by Casio. Uses a combination of Light Emitting Diodes and 445nm laser diodes as the light source, while image is processed with DLP (DMD) chip.

One product of projectors from ViewSonic is PJD6531W. The PJD6531w is an advanced 120Hz/3D ready DLP projector which includes Brilliant Color technology to produce more vibrant colors, while the high brightness and contrast ratios make this projector shine in virtually any lighting situation. The PJD6531w delivers 3000 lumens with a 1280 x 800 WXGA native wide resolution. This projector is designed for table-top use or can be mounted on the ceiling for classrooms and meeting rooms. The top load lamp and filter-less design provides for easy maintenance and low total cost of ownership. RJ-45 connectivity enables distant network try, patch the sweeping signaling options and organic 10W speakers give for awing multimedia show and effectual presentations or room lessons.

Brilliant Color Technology
Color is one of the most important characteristics of a good projection system, and the latest Brilliant Color technology delivers stunning all-digital clarity with lifelike color, sharp graphics and outstanding video. The sophisticated 6-segment color wheel enhances the yellow color performance that is key to accurate and vivid color reproduction. With multi-color processing, colors are richer and more vibrant with exquisite and precise detail.

DLP Technology
Advanced DLP (Digital Light Processing) technology allows you to experience crystal clear, razor-sharp and lifelike images with the same DLP technology that Hollywood relies on. For fast action, the response time is also on the order of 1,000 times faster than similar LCD based projectors. And with no air filters to clean or change, the latest generation of DLP based projectors from ViewSonic offer amongst the lowest TCO (total cost of ownership) in the industry.

DLP® 3D Technology
With support for TI’s DLP Link technology, you’ll have amazing 3D capabilities at your disposal. The projector’s embedded emitter function means all that’s required to unlock 3D capabilities is a pair of DLP Link compatible glasses, such as the optional ViewSonic PGD-150 active shutter glass kit.
