FEATURES
● 12V application.● Built-in VR-tube, only add a resistance to IC VDD-pin if under 12V, no external VR-tube needed.
● Adopts the built-in signal reshaping circuit to achieve the signal waveform shaping, and thus no signal waveform distortion takes place.
● Built-in power-on reset and brown-out reset circuits.
● The gray levels of each pixel of 256 levels, and the refresh frequency reaches to 2KHz.
● Serial cascading interface, data receiving and decoding are all achieved by one signal line.
● Signal Break-point Continuous Transmission, any pixel’s failure, it won’t affect the whole display effect.
● The distance of any two signal transmission points is less than 5 meters, there’s no extra circuits needed.
● When the refresh rate of 30fps, the cascade number are not less than 1024 pixels.
● Send data at speeds of 800Kbps.
● Good consistency reliability, high cost-effective.
