LED Signs “101”
Required Knowledge Before Shopping
Before purchasing an LED sign for your business you must understand how to compare all manufacturers. This will ensure that you receive an “apples to apples” product comparison from each potential LED company. All LED displays are constructed on (3) principles (Regardless of LED Manufacturer):
- Pixel Pitch (a.k.a.) Resolution
- LED Screen Size (a.k.a.) Sign Matrix
- Total Number of LEDs per sign face
What sets adVISION LED apart is that we provide a dedicated laptop computer pre-configured to communicate with your display. Our adVISION LED Software allows you to combine text, photos, video and animation. You will be able to scale, crop, animate and add creative effects to your digital messages.
“You must understand, what is an LED pixel. Pixel – refers to the smallest unit of measurement, when dealing with LED signage. The pixel will consist of Red, Blue and Green LEDs, which will give your display the ability to produce all colors. Typical pixels manufacturers use will contain either: (3) LEDs per pixel or (4) LEDs per pixel. See Pic.1
Principle 1 – Pixel Pitch or Resolution
Pixel Pitch – refers to the distance from the center of one pixel to the center of the adjacent pixel.
Simply put: the smaller the pixel pitch is the closer the pixels are one to each other, the better
Ex. A sign with a (20)mm resolution has a higher definition than a sign with a (25)mm resolution
A sign with a (16)mm resolution has a higher definition than a sign with a (20)mm resolution
A sign with a (12)mm resolution has a higher definition than a sign with a (16)mm resolution
The pixel pitch is the most important aspect of creating quality videos and graphics, if you do not have enough pixels on your LED screen you will not have clear videos. The smaller the (mm) resolution the better the image that will be produced.
Principle 2 – LED Screen Size or Sign Matrix
Sign Matrix – refers to the actual space on your display that is populated with pixels. This will contain (2) numbers Matrix Height – how many pixels tall the screen size will be Matrix Width – how many pixels wide the screen size will be These numbers are mandatory to compare one company to another. All LED signs have a matrix height and matrix width, regardless of resolution. These numbers give consumers a true comparison from one LED company to another, compare sign matrix, not cabinet dimensions.
Ex. Let’s look at (3) different resolutions that are approximately 4″ x 8″ in size:
(16)mm resolution Matrix Height: 64 (X) Matrix Width: 144 = Total Pixels 9,216
(20)mm resolution Matrix Height: 48 (X) Matrix Width: 112 = Total Pixels 5,376
(25)mm resolution Matrix Height: 40 (X) Matrix Width: 88 = Total Pixels 3,520
Principle 3 – Importance of Total # of LEDs per Sign Face
The most important aspect of your LED display is how many actual LEDs are on your screen. The more LEDs you have the better the picture quality will be, the better your advertising messages will look, which translates in a higher return on your investment. How To Calculate Total Number of LEDs per Screen
Step1: Find out how many pixels: Sign Matrix Height (X) Sign Matrix Width = Total # of Pixels
Step 2: Calculate Total # of LEDs Per Signs Face: Total # of Pixels (X) # of LEDs Per Pixel= Total # of LEDs/FaceEx. A Sign that has a resolution of (16)mm, sign matrix 64 x 144 and had (4) LEDs per pixel How would you calculate the total number of LEDs? 64 x 144 = 9,216 x 4 = 36,864 Total LEDs Per Sign Face
* LED signs are similar to buying a TV, the more LEDs you have on your screen the better the resolution or picture quality will be.
