1. Integrated network transformer, simplify design and improve electromagnetic compatibility 2. With MCU design, improve product application flexibility 3. Support dual card backup work, improve stability and reliability 4. Powerful LED driver chip compatibility 5. It can be widely used in high-end display fields with high requirements, and has significant advantages in application scenarios such as rental LED screens, TV live broadcasts, -scale event LED screens, and high-end engineering channel projects. 6. Support point-by-point brightness and chromaticity correction, cooperate with the correction software to correct the brightness and chromaticity of each light point of the screen, effectively the color difference, make the brightness and chromaticity of the display screen highly consistent, and improve the picture quality of the display screen quality. 7. Support multiple display effect schemes Cooperate with AutoLED software to achieve refresh priority and grayscale priority effects. 8. Support 90 multiple rotation of the screen With AutoLED software, it can rotate the receiving card screen in multiples of 90. 9. Support screen zoom function Cooperating with AutoLED software, the pixels loaded by the receiving card can be multiplied and to realize the zoom-in and zoom-out of the display screen.
