What is an SMD LED Screen?
what SMD LEDs are, and what the advantage is then here’s a little more information for you!
The more commonly used LED panels on outdoor screens are known as “through the hole”. They usually have 3 or 4 separate coloured LEDs (1 red, 1 blue & 1 green or 2 red, 1 blue & 1 green) which are pushed through a hole in the LED panel. These four LEDs make up one pixel on the panel, and the distance between an LED of one pixel and an LED of the next pixel is the true pixel pitch of the screen. Screens of this nature often use pixel sharing, which gives you a virtual pixel pitch (half the distance of the true pitch).
In contrast to this, SMD simply stands for “Surface Mounted Display” – and, as suggested, the LEDs are mounted onto the LED panel. SMD LEDs are tri-colour, giving you the three primary colours – red, green and blue – within the one LED.
SMD LED’s have been around for a while, but mainly for indoor use only because the IP levels weren’t correct for dust and water ingress. The brightness lev
els of the LEDs also weren’t suitable for outdoor use in daylight and especially bright sunlight. Now, as the technology has developed, the brightness is much better for outdoor use and they have the correct IP levels so they’re slowly venturing into the outdoor LED market.
The advantage of SMD LEDs is that they take up less space on the LED panel, meaning you can see more black on the back of the panel around the LED and this gives you better black levels and contrast on your screen picture. The SMD LEDs also don’
t need to pixel share, so you only have a true pixel pitch and no virtual. This avoids any potential loss of quality with a picture or text appearing blurred that you may get with a virtual pixel pitch.
