Projectors


Covix Group supplies and installs projectors ranging from the smallest for a Boardroom , to the brightest on the market for projecting onto a giant surface such as a building. To achieve this, it is necessary to choose the right projector in combination with the right lens.

In a Boardroom, we will always try to achieve a clean installation, hiding the projector in a ceiling thanks to an electromechanical support if required.

In the case of an outdoor projection, we must take into account other factors, such as the incorporation of hardware and software that allow us to do video mapping on buildings and thus project according to the relief of the desired surface. Let us advise you on the best option for your projection needs.

LCD (Liquid Crystal Display) Projectors The difference between a DLP projector and an LCD projector lies in the way the image is projected using a lamp light source.

LCD projectors display images using red, blue, and green rays that pass through individual LCD panels.

These rays are combined using a dichroic prism to project the image through a lens.

LCD projectors are the best choice for business presentations or use in medium to large boardrooms due to the brightness (high level of illumination) they produce. They are also very practical due to their compact size, light weight and low power consumption.

Currently, 3LCD reflective laser projectors are used which do not have a color wheel, therefore providing blacker blacks, whiter whites and brighter, more vibrant colors.

The important points before purchasing an LCD projector should be: Resolution, Proportion, Contrast, Brightness and Sharpness. The most common resolutions for LCD projectors are: 1280 x 720, 1280 x 768 and 1920 x 1080.

Aspect ratio refers to the size of the screen.

Commonly, a projector's aspect ratio is 4:3 or 16:9. For example: 4:3 means that for every 4 units in width, the screen is three units in height.

Contrast is the difference between light and dark areas in an image. Better contrast results in a more detailed image.

Brightness refers to the amount of light passing directly from the image source to the lens and is measured in lumens.

As there is little light loss, better images are obtained. Sharpness will provide us with clearer images, texts and graphics.

DLP

​DLP

DLP (digital light processing) projectors
All DLP projectors have a DMD (digital micromirror device) chip inside, covered with thousands of microscopic mirrors that allow the light to come out with the correct colors, passing through a lens to project the image.

On its own, the image produced by the DLP chip is seen in black and white. Colour images are usually produced using two methods: the single-chip method or the three-chip method. The latter uses one DMD for each primary colour (red, green, blue) which optically converge to produce a single image.

Single-chip DLP projectors alternate red, green and blue many times per second, creating a disorienting optical illusion called the "rainbow effect" that is particularly pronounced in images that have sharp edges between light and dark areas, such as presentation slides.

The difference between a DLP projector and an LCD projector lies in the way the image is projected using a lamp light source.

​Laser Projectors

Two important aspects to consider when purchasing a laser projector are that they do not use lamps and the speed of turning on and off is much faster. These benefits make this technology one of the best in terms of savings on the purchase of lamp replacements, no technical support and few or no repairs.
Its main features are: greater durability without the need for maintenance, longer lifespan of up to 10 years, constant maximum brightness level throughout its lifespan, low energy consumption.

​Interactive Projectors

Turn any smooth, light-colored surface into a touch screen for drawing, writing, sending or printing documents.
With these projectors you can use your fingers to interact directly with the screen or use interactive pens simultaneously. These projectors have the ability to interact wirelessly with iOS and Android mobile devices.
