New generation digital led is specially designed for high resolution display application, each channel with 16bit gray scale, 4bit gamma correction inside, can achieve 20bit display effect With 10KHZ Port refresh frequency. High- tech integrated digital led, no need any external components including capacitor; Dual input and output signals, automatic switching to ensure reliability; 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 48bit 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 48bit. 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.

• 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: R,G,B 65536 gray scale(Built- in 4Bit GAMMA correction).
• Port with 10KHz refresh frequency.
• Cascading port transmission signal by single line.
• 2.2mm2.0mm0.84mm, Super tiny size

• LED transparent screen, LED pixel screen, LED special- shaped screen, various electronic products.
