RGB/Dual color/ Single color LED Ring Display new product release！
Introducing OPTO PLUS LED Corp’s latest product for 2023: a ring display with a hollow center, designed to integrate seamlessly with customers’ products to function as ambient ring lighting. This product is part of our standard line, with the emission color adjustable through the standard product customization process. For more details, please refer to the Standard Product Customization webpage. By paying a minimal tooling cost, the emission color can be tailored, offering options for single-color, dual-color, or RGB emitting LED ring displays.
Below is a brief introduction to the product and key points to note.
The Appearance of the LED Ring Display
The Appearance of the Dual-Color LED Ring Display
The appearance and size of LED Ring Displays, whether they are single-color, dual-color, or RGB, are all the same. The only significant difference lies in the number of pins. Although the number of pins may vary, they are evenly distributed around the circumference to ensure that the product’s center of gravity and the weight distribution on the base remain balanced.
The LED ring display currently in production has a unique appearance, unlike any existing standard display products. It features two concentric circles with an inner diameter of 44.5mm and an outer diameter of 54.3mm. The display is connected to the PCB using four pins positioned at the top, bottom, left, and right. The LEDs change color based on the voltage input, creating a slow fading or dimming effect, similar to ambient lighting. Below are images showing the front view of the LED ring display and the dimensional diagram from the datasheet.
Internal Circuitry of the LED Ring Display
Internal Circuitry of Dual-Color LED Ring Display
The internal circuitry of the LED ring display differs based on the type and number of LEDs used. For instance, the OPD-DR54PGLE-Z-W, a dual-color configuration, contains 28 LEDs per color connected in parallel. The red LEDs are controlled through PIN1/PIN2, while the green LEDs are controlled through PIN3/PIN4. By controlling all pins simultaneously, both colors can be activated, creating a mixed light effect. The diagram below shows the internal circuitry from the OPD-DR54PGLE-Z-W datasheet, along with a demo video of the illuminated display.
Internal Circuitry of RGB LED ring display.
The internal circuitry of the LED ring display varies based on the type and number of LEDs. For example, the OPD-DR54RGB-W is equipped with 28 RGB LEDs connected in parallel, capable of producing mixed light. The illumination of each RGB LED can be controlled via PIN1/PIN4 using commands. Unlike dual-color LEDs, command control allows for individual control of each LED, enabling complex ambient lighting effects that are not possible with dual-color setups. Below is the internal circuitry diagram from the OPD-DR54RGB-W datasheet, along with a demo video showcasing two illuminated displays.

FAQ
In 2023, Opto Plus launched a new round LED display with a hollow center that can be used to create a ring-shaped ambient light.
This display is a standard product, but its light-emitting color can be adjusted through a standard customization process. For a small mold fee, you can create a round LED display that emits single-color, two-color, or RGB light.
This round LED display is composed of two circles, an inner and an outer one. The inner circle has a diameter of 44.5mm, and the outer circle has a diameter of 54.3mm.
Whether it’s a single-color, two-color, or RGB round display, the external dimensions are the same, but the number of pins differs. The pins are evenly distributed around the circumference to keep the product balanced and ensure stable contact with the baseplate.
For the OPD-DR54PGLE-Z-W model, which is a red and green two-color configuration, each color has 28 LEDs connected in parallel. The red LEDs can be controlled via PIN1 and PIN2, while the green LEDs are controlled via PIN3 and PIN4. Controlling all pins simultaneously allows both colors to light up, creating a mixed-color effect.
For the OPD-DR54RGB-Z-W model, the display has 28 parallel RGB LEDs, and each LED’s light emission can be controlled individually using PIN1, PIN4, and commands. Unlike the two-color LED, the RGB LED can be controlled individually to achieve more complex ambient lighting effects.
If you need to fine-tune the color or circuit of an existing round LED display, you can visit the standard customization webpage on the Opto Plus website. If you require a fully customized round LED display, you can submit your requirements.
