on.  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 transm
