WS2816A

Featur es and Benefits

•  The control circuit and RGB chip are integrated in a package of 5050 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.
•  OUTR / G / B output gray level: 65536 gray scale levels.
•  The port scanning frequency is 10KHz.
•  Data transmission speed up to 800Kbps
•  Dual input and output signals, in case of damage of the single pixel, does not affect the overall display effect.
•  Serial cascade interface, it's able to receiveand decodie data through a single signal line.
•  Color mixing consistency is excellent, high cost and performance ratio.
•  Each channel carries a 32 level current gain.

Applications

•  LED transparent screen, LED pixel screen, LED special-shaped screen, and various crystalline film screen.
•  A variety of electronics.

Gener al Description
The WS2816A is a new generation of digital LEDs developed for high-definition image display applications, with up to 16bit grayscale data per channel, the port refresh rate is up to 10KHz, while each channel carries a 32 level current gain, which is ideal for large image displays. With highly integrated driver and RGB chips in a 5050 component, no external capacitors are required.

The data protocol adopts single NZR communication mode, after the pixel is power reset, the DIN reveives the data transmitted from the controller, the 48bit data sent over first is extracted by the first pixel and sent to the data latch inside the driver, the remaining data is amplified by the internal shaping amplication circuit and then begins to be forwarded and outputted to the next cascade of pixels through the DO port, and the signal is reduced by 48bit for each transmission of one pixel. The signal is reduced by 48 bits for each pixel. The driver adopst automatic reshaping and forwarding technology, so that the number of cascaded pixels are not limited by signal transmission, but the signal transmission.
