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 Projectors (Liquid Crystal Displays) 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 light beams 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. Furthermore, they are very practical because of their compact size, light weight, and low energy consumption.

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

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

The aspect ratio refers to the screen size.

Typically, 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 has 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 that passes directly from the source image to the lens and is measured in lumens.

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

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

On its own, the image formed by the DLP chip appears in black and white. To produce color images, two methods are typically used: the single-chip method or the three-chip method. The latter uses a DMD for each primary color (red, green, blue), which converge optically 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.
