Intelligent reverse connection protection ensures that power reverse connection will not damage the IC. The IC control circuit shares a power supply with the LED point. The control circuit and the RGB chip are integrated in a 5050 packaged component to form a complete external control pixel. Built-in signal shaping circuit; any pixel point receives the signal after waveform shaping and then outputs it, ensuring waveform distortion does not accumulate. Built-in power-on reset and power-down reset circuits. Each pixel can achieve 256 levels of brightness, enabling full display of 16,777,216 colors, with a scanning frequency of no less than 400Hz. Serial cascade interface allows data reception and decoding through a single signal line. When the transmission distance between any two points is less than 5 meters, no additional circuit is required. At a refresh rate of 30 frames per second, the number of cascaded points is no less than 1024. Data transmission speed can reach 800Kbps. Light color is highly consistent and cost-effective. Main application areas: LED full-color luminous character string light, LED full-color module, LED full-color flexible light bar, hard light bar, LED guardrail tube. LED point, LED pixel screen, LED special-shaped screen, various electronic products, electrical equipment marquee.
