Category: RGB LED Strips and Drivers

WS2812B-2020 is an intelligent control LED light source, its exterior adopts the latest MOLDING packaging technology, and the control circuit and RGB chips are integrated into a package of 2020 components. It’s internal includes an intelligent digital port data latch and signal reshaping amplification drive circuit. Also includes a precision internal oscillator and a voltage-programmable constant current control part, effectively ensuring the pixel point light color height is consistent. The data transfer protocol uses a single NZR communication mode.

After the pixel power-on reset, the DINport receives data from the controller, the first pixel collects initial 24bit data and then sent to the internal data latch, and the other data which is reshaped 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 24bit. pixel adopts auto-reshaping transmit technology, making the pixel cascade number not limited to the signal transmission, only depending on the speed of signal transmission. RESET time >280μs, it won’t cause the 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.
