What You Should Consider When Buying An LED SCREEN


Permission – From the landlord, Property owner, and sometime from the relevant municipality.

Display brightness – For outdoor the display should be at list 6500 NIT in order to be seen well

during broad daylight, Indoor screens  depends on the ambient light should be in the range of

1800-2800 NIT.

Pixel pitch – should be suitable for the viewing distance that you require, The smaller the pitch

the closer the distance that the screen can be viewed comfortable, Keep in mind that the closer



the pitch,number of pixels per m2 is higher – and so is the price.

Structure – depends weather the sign will be mounted on a wall or on single or multiple poles

– We can offer you the best solution.

Communication – many options are available, depends on the client’s needs and networks

 Understanding RGBTerms and Definitions


LED – Light Emitting Diode, The part that convert electrical current into light, The screen is made of 3

colors LEDs : Red, Green, Blue ( Called also RGB Screens).

The LEDs are the Most important parts of the display, the determine the brightness, Viewing angle and effecting the display life.

LED TYPES: DIP -individual LEDs – usually 1 for Red, 1 Green, 1 Blue per Pixel, SMD led Type, all 3 are

in one capsule, Physically smaller than DIP, usually used in small pitch sizes mainly  for Indoordisplays, Different sizes available.

PIXEL – This is the primary part of the display, made of LEDs, and consist all the colours that can be displayed.

ENTIRE SCREEN – The complete display made of a Structure, Several cabinets, Control System

consisting of industrial PC, Sending Card, Cables, Main supply.

RECEIVING CARD – This card receives the video signal from the sending Card and translate it into digital pulses to switch on the LEDs as required to illuminate the required colour and intensity.

SENDING CARD – The card gets the video signal from external device via DVI input, and send the video image to the receiving cards.


PITCH – The distance between two close pixels, The lower the pitch – the better the picture quality.

MODULE – This is an array of pixels in  plastic case, Complete unit, includes PCB, Driving ICs and

components, LEDs and epoxy for waterproofing ( OUTDOOR DISPLAY).

CABINET – An enclosure, Consist of several Modules including Power Suppliers, Ventilation, Receiving

Card and cables.
