Same Parameter
WS2812B and APA102 are integrated with driver IC and wide application Increases safety by better device
reliability and visibility Save energy and maintenance cost Create more than one billion colors Entire cabinet
comply with IP66 Replace neon lamp,
l Both of them have Intelligent reverse connect protection, the power supply reverse connection does
not damage the IC.
l The control circuit and the LED share the only power source.
l Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point.
l Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
l Built-in electric reset circuit and power lost reset circuit.
l Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan
frequency not less than 400Hz/s.
l Cascading port transmission signal by single line.
l Any two point the distance more than 5m transmission signal without any increase circuit.
l When the refresh rate is 30fps, cascade number are not less than1024 points.
l Send data at speeds of 800Kbps. The color of the light were highly consistent, cost-effective
