Addressable RGB LEDs

JN White® is leading the industry in the integration of addressable RGB LEDs into custom solutions where traditional LED strips will not work. Addressable RGB LEDs can be individually programmed to display colors that differ from surrounding LEDs that share a strip, giving product engineers greater control when it comes to backlighting and user interface displays. These applications are particularly helpful for components with custom shapes and/or miniature footprints.

Addressable RGB LEDs Capabilities

Over 16 Million Unique Colors

Addressable RGB LEDs gives engineers over 16 million color choices to create virtually any light display imaginable

Individually Programmable LEDs

Each LED is individually programmed, giving engineers unlimited flexibility to choose color and timing of LED firing

Ultimate Control Over LED Display

Fully customizable LED units mean engineers can control every aspect of their LED display

How Addressable LEDs are Different

A commonly used form of LED lights is the 3 channel LED strip, which has three different ground circuits and a shared voltage. Each unique ground channel controls a different color of light, either red, green, or blue. By changing the resistance on those channels, engineers can adjust the color and brightness to display their desired colors. However, since 3 channel LEDs share a common set of data, the entire strip of LEDs will display the same color at the same time.

On the other hand, individually addressable LEDs contain data on the LED level instead of the strip level. Each LED light can be individually programmed to show a different color, which is accomplished by adjusting each LED’s individual brightness. The color can vary on every LED that shares a strip. Each LED contains a microcontroller chip that allows the user to directly control the color and timing of the individual LED.

When to Use Addressable RGB LEDs

3 channel LED strips remain a great option for product developers who don’t require LEDs on the same strip to display different colors, or who are on a limited budget. Those who are looking for a high-tech, multi-colored, and interactive solution should consider individually addressable RGB LEDs in their product.

How Addressable RGB LEDs Work

Each LED contains a microchip with a positive voltage wire, a ground, and a data wire. On the strip, LEDs are labeled as LED0, LED1, LED2, and so on. Each LED needs to have specific instructions about what to do and when. 

Developers create a program through the microcontroller’s PMW signal (pulse, width, modification) that instructs the LEDs on what color to display and when, following a DO (data input pin) structure. LED0 reads and follows the instructions programmed for LED0, and then passes the data onto LED1, which reads and follows the instructions for LED1, and then passes on the data to LED2, and so on, until each LED has received specific instructions. This creates a light display of multiple colors concurrently.

Creating Color with Addressable RGB LEDs

The RGB method uses a combination of red, green, and blue light to create color. Addressable LEDs can display over 16 million unique colors through a blend of their red, green, and blue components at 255 different levels of brightness. Outputs are combined from red, green, and blue to create the desired color. While most colors are possible using this method, it’s important to note that some fall out of the scope of RGB capabilities. 

A new innovation has been brought to the RGB LED method, called WRGB (or RGB +W), which is a standard RGB LED with an added white (W) LED, which adds an additional chip to the LED strip. While a WRGB LED allows more color flexibility than an RGB LED, it also comes at a higher cost. For basic RGB colors with no requirement for a proper white, a standard RGB LED strip is generally more cost-effective.

An additional difference between WRGB and RGB LEDs is the controller. The WRGB controller has five outputs, one for each color (red, green, blue, and white) and one for power. The RGB controller only requires four outputs. It also requires a different PMW signal to control the white in an RGB LED.

"Very pleased with your team's response to our need during the COVID-19 crisis."
Lisa L., Medical Device
"JN White has been exceptional in working with our company in order to develop the look and feel of our new MRI patient worn transmitter. We had originally worked with a prior manufacturer for an earlier version of this product with much less desirable results. JN White delivered a clean professional product at a very reasonable price on time!"
Gary P., Medical
"We had very little information to work with and Jessica James made it nearly effortless on our end to get us exactly what we needed in a timely manner."
Lexi W., Industrial Equipment
"Getting any after-market graphic overlays done always has a certain risk factor in getting it all right. You guys were helpful, patient, & knowledgeable to achieve the best end result. Even pointing out some things that might be [an] oversight or [areas for] improvements. The outcome was perfect."
John S., Technology
"The print task was between the USA and Australia and everything went so smooth. I submitted a drawing, got a return email for me to confirm what I wanted. Even though this was over the Christmas period the print was waiting for me when I got back to work after the holidays. Great job and thanks."
Matt C., Military
"All of the folks there at JN White that I have talked to and dealt with have been very nice and professional."
Vern L., Industrial
"Customer service is wonderful. Receive confirmations and responses in a timely manner. Product has great quality."

"It has been a pleasure working with JN White. We switched suppliers for some of our products to your company and you have given us higher quality. Excellent work!"
Roger W., Education
"I feel confident that JN White will do my order correctly."
Marie P., Government
"I found working with Sara to be a pleasant experience. We were trying to dial in the color to get just the right look on the printed substrate...Sara sent us a sample print sheet that had several variations, up and down, from the colors we specified, which allowed me to pick exactly the color we wanted. The end result product is perfect!"
Don M., Safety
