The color LED module contains four adjustable full-color gamut RGB LEDs. The color of each LED is determined by the values of the three primary colors: red (R), green (G), and blue (B). Each RGB LED integrates a control chip internally, enabling independent full-color functionality with just a single signal line. It features high brightness and adjustable brightness, allowing for effects such as running water flashing and rainbow lights.
The data protocol of the RGB light adopts a single-line return-to-zero code communication method. After the pixel point is powered on and reset, the DIN terminal receives data transmitted from the controller. The first 24-bit data sent is extracted by the pixel point and sent to the internal data latch of the pixel point. The remaining data is shaped and amplified by the internal shaping processing circuit, and then forwarded and output to the next cascaded pixel point through the DO port. For each transmission through a pixel point, the signal is reduced by 24 bits. The pixel point adopts automatic shaping and forwarding technology, so the number of cascaded pixel points is not limited by signal transmission, but only restricted by the signal transmission speed requirements.
