Screens

Flat Panel Displays

The flat panel revolution began with plasma technology, using a widescreen format (16:9) that arrived even before high definition signals. Plasma evolved until it was replaced by LCD technology. Screens with this latter technology, in addition to presenting less hum and less heat emission, were rapidly increasing in size and resolution, consolidating themselves as the most viable option in flat screens. Some time later, their light source was changed and went from being a simple lamp (CCFL) to being a set of LEDs . Plasma technology has become obsolete in the consumer market, however it continues to be used in the professional market since it is the technology with which a thinner frame is achieved (PDP technology).

It is commonly thought that LED screens were the next step after LCD screens, but it would be more correct to say that LCD screens now have LED lighting. When we talk about LED screens, we are not referring to this type of screen, but to those with the LED exposed, which are easily distinguished outdoors in spectacular advertisements.

The various Asian flat screen manufacturers, in any of the variants shown, have reduced costs and with this have strongly penetrated the consumer market. However, it is very important to differentiate a traditional consumer screen from a heavy-duty screen. The former are designed to remain on for only a few hours a day, while heavy-duty screens have the necessary electronics to remain in continuous use, without needing to be turned off. Their power source and the electronics that generate the most heat can even be removed from the screen and sent to a rack, keeping the heat as far away as possible from the liquid crystal of the screens. With this we will avoid image retention (image sticking), a natural effect of LCD screens, caused by the static display of images in the same position.

It is essential to choose the screen that best suits the needs of each application. Let Grupo Covix advise you in choosing screens for your project, whether they are screens for Digital Signage , screens for Videowall , heavy-duty screens, outdoor screens, etc.

Front Projection Screens

Nowadays we can find dozens of different projection screens , each one made with different materials and colors, therefore with different characteristics, particular features that if we know how to take advantage of them, can offer us a better result in the images to be observed. The ideal projection screen is the one that best adapts to the characteristics of the projection room. Factors such as the instrument that will project the image, the distance between the projector and the screen, the characteristics of the projector and the luminosity of the place must be taken into account.

A projector screen can be white, pearl or semi-silver, among others, and the result presented by each of these is very different. For example: if the surface is white, the blacks and dark colors will be very intense but the light colors will look pale. If we use a semi-silver or glass screen, we run a great risk of the colors being distorted, which can result in a somewhat poor presentation. That is why we emphasize that without being a rule, the almost ideal projector screens are those with a matte finish, since this correctly regulates the intensity and definition of the image in proportion to the color.

Among the most common types of projection screens are: manual, electric, tripod, rear projection screens, portable, foldable, special whiteboards, interactive and ceiling-mounted.

Videocubos

A video cube is nothing more than a rear projection system, consisting of a chassis, a projector, a mirror and a screen. They are generally found in standard sizes, such as 50", 67" and 70" diagonally. When a larger size is required, it is recommended to change to a custom-made rear projection screen system. The latest generation of video cubes offer lighting systems with LEDs instead of lamps.

This represents a substantial saving since the maintenance cost of the video walls will not require the replacement of lamps. Thus, while the lighting system consists of an LED projector, the image is formed thanks to DLP technology. This is the only technology that, unlike LCD or PDP technology, will prevent the marking or burning of a static image on the screens.

It is important to consider that even when there are video cubes that allow front as well as rear access for servicing, it is always advisable to leave a space behind them, or make a small back room that makes adjustments easier. Covering, masking or leaving a finish around the video cubes is a good practice that makes the video wall look as a whole without its depth being noticeable. Allow our company to suggest these finishes with an interior design that enhances the aesthetics of your Control Center.

Touch screens

A touch screen allows the user to interact with the content on the screen by touching its surface and selecting options that will guide them towards a particular objective. Due to their high luminosity, multi-touch system with excellent response and different sizes, touch screens can be used in Retail , Kiosks , Video Walls, Remote Points of Sale (POS).
