Introduction

WS2812B - 2020 is an intelligent control LED light source, its exterior adopts the latest Molding packaging technology, the control circuit and RGB chips are integrated in a package of 2020 component. Its internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and voltage programmable constant current control part, which achieves highly consistent color effect. The data transfer protocol use single NZR communication mode. After the pixel power - on reset, the DIN port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission. RESET time >280μs, it won't cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU. Refresh Frequency updates to 2KHz, Low Frame Frequency and No Flicker appear in HD Video Camera, it improve excellent display effect. LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angle is large, good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation.

Features

• The control integrated circuit and the LED share the only power source.
• Control circuit and RGB chip are integrated in a package of 2020 components, to form a complete addressable pixel.
• Built - in signal reshaping circuit, after wave reshaping to the next driver, ensure wave - form distortion not accumulate.
• Built - in electric reset circuit and power lost reset circuit.
• OUT R/G/B output gray level: 256 gray scale, complete 16777216 full color display effect.
• Port Refresh frequency is of 2KHz.
• Serial cascade interface, data receiving and decoding depend on just one signal line.
• When the refresh rate is 30fps, cascade number are not less than 1024 pixels.
• Send data at speeds of 800Kbps.
• The color of the light is highly consistent, cost - effective.
• Rated working voltage at 5V (the maximum working voltage shall not exceed 7V). It will not be damaged by reverse connection.
• When the LED is in static state (the DIN port does not send a signal), the VDD port can withstand 12V, which can prevent misplugging and misoperation.
• The peripheral circuit does not need to add any filter capacitor.

Applications

• Consumer electronics.
• LED decorative lighting, LED Screen.
• Computer and related equipment, game equipment, various electrical equipment field.
