Screens and Displays

Today, many kinds of displays and screens can be found in both, the consumer and professional market. This variety can lead to confusion, which is why we must know which display or screen is the one that meets the purpose of each application. It is important to choose screens or displays for every kind of application, whether for Home Theater entertainment in a residence, for Digital Signage in a shopping mall or for a Videowall in which a CCTV system, that requires high specification displays to operate 24/7 without presenting any markup, can be monitored.

Grupo Covix, with its sales area and support staff, can advise you with the best choice of screens or displays according to the Planning, Engineering and Design made by our technical support team. Within our representations range, we can find the following groups of screens and displays:

Flat Panel Displays

The widescreen revolution began with flat screen plasma technology, using a wide format (16:9) that came even before the high-definition signals. Plasma kept evolving until it was replaced by LCD technology. Displays with this technology, as well as presenting a lower buzz and lower heat emissions, were increasing rapidly in size and resolution, establishing itself as the most viable option for flat displays. Later it changed its source of illumination and went from being a simple lamp (CCFL), to be a set of LEDs. Plasma technology has become obsolete in the consumer market, however it is still used on the professional market, as it achieves a slimmer frame technology (PDP-Plasma Display Panel).

It is commonly thought that LED screens were the step that followed the LCD, but the truth is that LCD screens now have LED lighting. When properly speaking of LED displays we are not referring to this type of display but to those with the LED exposed, easily distinguishable in exterior billboards.

The different Asian manufacturers of flat panel displays in any of the exposed variants have reduced costs and as a result, have strongly penetrated the consumer market. However, it is very important to differentiate a screen of traditional consumption to a screen of rough use. The first is designed to remain switched on for only a few hours a day, while those of rough use feature the electronics necessary to remain in continuous use without the need to be unlit. Its power source and electronics that generate heat can even be drawn from the display and sent to the rack, keeping the heat as far as possible from the screen’s liquid crystal. This method avoids image retention (image sticking), the natural effect of LCD displays, caused by the static deployment of images on one position.

It is essential to select the screen that best suits the needs of each application. Allow Grupo Covix to advise you on the display choice for your project, whether digital signage displays, Videowall displays, rough use displays, outdoor displays, etc.

Front Projection Screens

Nowadays we can find dozens of different projection screens, each made with different materials and colors, resulting in different features, which if you known how to take advantage of, can offer a better result in the image’s clarity. The ideal projection screen is the one that is best suited to the characteristics of the projection room. We must take into account factors such as the instrument that will project the image, the distance between the projector and the screen, the projector features and brightness/luminosity of the place.

A projection screen can have white, pearl or semi-silver color, among others, and the result presented by each one of these is very different. For example, if the surface is white, black and dark colors will be very intense, but light colors will look pale. If we use a semi-silver or glass screen, there could be a risk of distorting the colors and having a somewhat poor presentation. Therefore, we emphasize that generaly the ideal projector screens are those having a matte finish, as these correctly regulate the intensity and definition of the image in proportion to color.

Among the most common types of projection screens are: manual, electric, tripods, rear projection screens, portable, folding, special boards, interactive and built into the ceiling.


A videocube is nothing more than a rear projection system, consisting of a chassis, a projector, a mirror and a screen. We usually find them in standard sizes, such as 50 ", 67" and 70 "diagonally.When a larger size is required, it is recommended to switch to a custom rear-projection screen system. They offer lighting systems with LEDs instead of lamps. 

This represents a substantial saving since the maintenance cost of the videowalls does not require changing lamps. Thus, while the lighting system consists of a LED projector, the image is thanks to DLP technology. This is the only technology that makes the difference of the LCD or PDP technology, it will follow the marking or burning of a static image on the screens. It is important to consider that even though there are videocubes that allow front access as well as rear access to service, it is always advisable to leave a space behind them, or make a small back room that facilitates adjustments. 

Lining, masking or leaving a finish around the videocubes is a good practice that makes the videowall shine in its entirety without distinguishing the depth of it. Let our company suggest these finishes with an interior design that enhances the aesthetics of its Control Center.

LED Displays

Las pantallas de leds se caracterizan por su alta luminosidad así como resistencia, por lo cual se acostumbran para exteriores. Los rayos del sol o el reflejo de la luz no son impedimentos para garantizar que las imágenes sean apreciadas desde cualquier ángulo de visibilidad.

La flexibilidad de esta innovación tecnológica ha permitido que su principal aplicación se haya dado en el área de la publicidad. Podemos apreciar enormes pantallas de LEDs colocadas en importantes edificios o sobre los estadios de eventos deportivos. De igual manera encontramos su uso publicitario en banners colocados en cualquier punto que tenga una gran afluencia de personas; por ejemplo: alguna salida de estación del metro.

A diferencia de otros dispositivos de proyección, las pantallas de LEDs son mucho más cómodas para transportar y no pesan tanto como las rígidas de cristal. Aunado a esto se pueden unir tantas pantallas como su instalación lo necesite, pudiendo ensamblar un display tan grande como se requiera. Una vez que la pantalla de LED está lista, es controlada mediante un software en el que se puede programar todo el evento y si se llegase a necesitar se tiene la posibilidad de introducir datos en tiempo real tantas veces como así sea solicitado.

Touch screens

A touch screen, allows the user to interact with the content of the screen by touching its surface and selecting options that will guide it towards a particular objective. Due to their high luminosity, excellent response multitouch system and different sizes, the touch screens can be used in RetailKiosks of sale, video walls, remote points of sale (POS). 

Grupo Covix offers a wide range of touch screen solutions for different environments and spaces, providing service and support to make any installation a success. 

With us you will find different solutions such as: Touch panels, touch monitors for PCs, Multitouch LED displays, Multitouch LED video displays, large format touch LCD displays, touch 4K (Ultra HD) displays; all these displays do not require any keyboard, saving valuable space and are easy to use for the end user.
