LED screen specifications sheet

LED screen specifications sheet

Perhaps it is trivial to underline it but the question remains essential; even the best LED display in the world will look terrible or at least much worse than it could be if the visual content is not of quality. With the availability of excellent production and content management software and the creative ability of many "Graphic Designers" in circulation today this should not be a problem but either due to the cost that this part of work may require or due to laziness or lack of knowledge of the specificities of LED video technology, it often happens that we see giant screens or even monitors, totems, banners with very little visual impact.

When proceeding with the purchase of a LED display, whether for indoor or outdoor use, for advertising, shops, sports, rental or information, it is essential to request, obtain and understand the product's technical data sheet in detail.

This technical data sheet must always and at a minimum include essential elements such as:

1. graphic definition (horizontal pixels by vertical pixels),

2. lPHYSICAL pixel pitch (distance between the centres of adjacent RGB dots);

3. resolution(number of pixels per square meter);

4. type of LEDs used (whether SMD or traditional);

5. brightness (in NIT, i e. candelas per square metre, > 5000 for outdoor use);

6. IP protection rating (65 for outdoor use) and horizontal/vertical viewing angle.

To this basic information other things should be added up, all very important to understand if the model is suitable.

7. Total weight, power supply;

8. maximum/average power consumption are required to prepare well the site and plan the total investment.

In this regards also screen depth and maintenance access (front or rear) must be considered from the very beginning.

More linked to screen performance are specifications like:

Something quite interesting that is not often included in the specs sheet is the character matrix, i.e. the minimum character height, maximum number of writing lines and maximum number of characters per line – often messages on LED screens are not readable because this matrix is not fully respected.

Connected to eletronic control systems are video inputs and outputs. And finally it is highly recommended to get clear information about 2 extremely important topics. 1) what kind of product certification will accompany the screen and if the certificate is issued by the supplier or an independent, recognised laboratory; who is the supplier/brand of LEDs, ICs, receiving cards and switching power supplies. The quality of the screen is given by the quality of the components used. At least the information about the LEDs must be provided with every possible detail.
