There are a vast number of different size displays, and the choice is growing all the time. For large format displays, over 100" is now readily available! However, the technology and the specialist choices are simple to explain:

LCD Liquid Crystal Displays LCD technology has been around for a long time, it is regarded as reliable. Displays using LCD produce bright images with a good contrast ratio.
LED Light Emitting Diode Although described as LED, these screens are actually LCD panels with LED backlight. They offer virtually maintenance free solutions which are comparatively low cost to run.

Large Format Displays –refer to a screen (like a tv), with a bezel around it. The format is usually 4:3 or 16:9 ratio. Some have specialist features:

  • 24/7 use. For applications which are constantly providing information.
  • Thin bezels. These are usually preferred in video walls to ensure a more cohesive image.
  • Ultra slim. Often preferred in retail environments where space is tight.


Installation projectors for all types of meeting areas and mobile projectors which can be easily carried wherever required.

For installations the things which will determine the projector specifications are: size of the room, throw distance of projector to the screen; ambient light of the room; budget available for the projector. There are a various projector technologies available, here’s our description of the main technologies involved:

DLP Digital light processing Projectors using DLP require little maintenance other than regular replacement of the UHP lamp. They produce a bright and well defined picture but they can sometimes give off a rainbow effect in the image. Some DLP use LED light source, this lasts a long time usually between 10,000 and 20,000 hrs and does not require replacement.
LCD Liquid Crystal Display LCD technology has been around for a long time, it is regarded as reliable. These projectors use UHP lamps as a light source, the lamp will need replacing regularly. The projector will also require a regular filter change to protect the light path from dust and fine particles in the air. Using LCD technology the projector is able to produce a vast array of colours and the technology is compatible with lens shift and zoom lens which are often required in large rooms.
LCoS Liquid Crystal on Silicon High resolution and picture quality, really good for video.
LED (light-emitting diode) lightsource. Sometimes as a hybrid with laser. This light source lasts between 10,000 and 20,000 hrs generally, dependent on the projector model. It is comparatively low energy technology and does not require replacing. The projector requires no warm up or cool down period, and using LED lightsource.
UHP lamps Produces a high light output. Will require replacing normally somewhere between 1,000 and 3,000 hrs dependent on the projector model. The lamps are usually supplied in a module making them simple to fit into the projector.

Interactive Presentation

Interactive technology allows the passive participant to take an active role in the presentation/lecture. This can provide a more stimulating and memorable environment as participants are encouraged to take part and add to the prepared material.

Normally interactive presentation is via a screen with a projector – usually front projection but rear projection is doable – or with an interactive LED display. It is also possible to make an existing display interactive.

Video and audio conferencing

Latest buzz around conferencing is unified communications which is about integrating all communication tools – telephone, video, chat, datashare – so that conversations, ideas, updates, instructions are shared quickly and effectively. This can be achieved in the cloud or using your own system if you have the capacity for maintenance and security.

Digital Signage

This is a quick way to update information both internally and externally. The software can either sit on the cloud or within your own system, and lots of special features are available such as managed access, scheduling, free templates and content and your content can be enabled to respond to interactive technology such as touchscreens.
