Product Information
The addressable RGBCW led backlight modules string provides wide-angle area illumination across architectural stretch ceilings, fabric light boxes, and back-lit accent walls. Each string contains 20 square aluminum modules measuring 90 × 90 × 6 mm with 20 cm connecting wire spacing, spanning a total length of 570 to 590 cm. Designed with integrated 170 to 180 degree optical lenses, each backlight led module disperses light across a shallow cavity depth without creating distinct hot spots. Every individual square unit functions as one addressable pixel containing 12 surface-mounted diodes (4 RGB, 4 Warm White, and 4 Cold White). Driven by the GS8306 dual-signal breakpoint-resume transmission IC, a single diode or component failure will not interrupt signal relay to subsequent modules on the run.
Key Features
GS8306 Dual Data Line
Continuous transmission ensures that if one square module encounters failure, downstream backlights modules continue operating without data interruption.
170 to 180 Degree Optical Lens
Wide beam distribution eliminates diode hot spots across shallow fabric lightboxes and architectural tension ceilings.
Full Spectrum RGBCW Control
Each module contains 4 RGB, 4 warm white, and 4 cold white emitters to deliver saturated dynamic color alongside tunable white tones.
Rigid Aluminum Substrate
Solid aluminum backing measuring 90 × 90 mm conducts thermal energy directly away from the emitters for stable continuous operation.
Pre-Wired JST-SM Connectors
Standard 4-pin JST-SM terminals on both ends simplify series connections and direct linkage to an addressable RGBCCT controller.
Technical Highlights
- Breakpoint resume data design: redundant signal path maintains pixel communication past any single damaged board.
- Equipped with 20 cm inter-module cables, establishing a center-to-center pitch of 28 to 29 cm for uniform grid layout coverage.
- Total array span of 570 to 590 cm per 20-module bundle, matching typical ceiling grid rows and large display framing.
- Paired directly with a stable external power source such as a 24V power supply sized to the total system load.
- Alternative planar layout solutions can also utilize programmable LED matrix sheets depending on enclosure geometry.

Application Scenarios
How to Install & Use This Light
- Turn off all mains power at the circuit breaker prior to handling wiring or power connections.
- Fasten the 90 x 90 mm aluminum modules to the interior rear panel using screws through mounting holes or rated structural mounting adhesive.
- Connect the 4-pin JST-SM terminal to the signal output of your SPI addressable RGBCCT 5-channel digital controller, observing V+, DI (Data In), BI (Backup In), and GND orientation.
- Turn on the power supply, configure your controller software to GS8206 or WS2811 compatible timing, and map each 12-LED module as 1 RGBCW pixel.
⚠ Precautions
- This product is rated IP20 non-waterproof; use exclusively in dry indoor enclosures and light boxes.
- Ensure data direction follows the directional arrows on each module.

Frequently Asked Questions
Q: What is the function of the GS8306 IC on this led backlight module?
A: The GS8306 IC features breakpoint resume data transmission with dual data lines. If a single module encounters damage or diode failure, data signals bypass the faulted pixel and continue driving the remaining units on the string.
Q: How many individual control pixels does one 20-piece string represent?
A: Each 90 x 90 mm module acts as one single addressable pixel containing 12 LEDs (4 RGB, 4 warm white, 4 cold white), resulting in 20 individually controllable pixels per full string.
Q: Can these backlight modules be cut or shortened?
A: Yes, you can cut the 4-wire interconnecting cable between any two modules to shorten the string to the exact module count required for your enclosure.
