Features at a glance: 
- Cascading port transmission signal by a single cable, with electric reset circuit and power lost reset circuit
- Also, built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion will not accumulate
- Each pixel of the three primary colors can achieve 256 brightness display, completed 16777216 full-color display, and scan frequency is not less than 400Hz/s
- When the refresh rate is 30fps, cascade numbers are not less than 1024 points, and the speed of data transmission is up to 800Kbps
- Widely use for LED decorative lighting, indoor or outdoor LED irregular screen
