The power supply has the characteristics of small volume, high efficiency, stable operation and high reliability. The power supply has input under-voltage, output current limiting, output short circuit and so on. The synchronous rectifier circuit greatly improves the efficiency of the power supply and saves energy consumption.

How to make the naked-eye 3D LED display ?
A: Need smaller pitch LED display, better with high refresh, video processor setting pixel by pixel, and play high quality 3D video.
After I change one of the receiver cards, it does’t work. How can I solve it ?
A: Please check the firmware. If this new card is different with other card, you can upgrade it into same firmware, then it will work.
If I lose my screen RCG file, how can I get it back ?
A: You can click “read back” to get it back in the software receiver page if you or provider have saved it before.
How to upgrade the firmware of Novastar cards?
A: In NovaLCT advanced mode, anywhere input admin, the upgrade page will come up.
How to upgrade the firmware of Linsn controllers？
A: In LEDset receiver setting page, anywhere input cfxoki, then the upgrade page will come out automatically.
How to update the firmware of Colorlight system ?
A: Need to download LEDUpgrade software
How to make LED display brightness change automatically in different time ?
A: It is required with light sensor. Some devices can connect with sensor directly. Some devices need to add multi-functional card then can install light sensor.
How to customize video splicer, like Novastar H2?
A: At first decide how many LAN ports the screen need, then choose 16 ports or 20 ports sender card and quantity, then choose input signal that you want to use. H2 can install maximum 4 input board and 2 sending card board. If H2 device is not enough, can use H5, H9 or H15 to install more input or output boards.
