1, light-emitting materials
Φ3.75 imported high brightness modules with a single red 8 × 8 lattice.
2, Screen power system
Using high-power switching power supply, power performance, small size, waveform stability and output power, voltage fluctuation value is small, the basic requirements to achieve constant current, and has automatic protection.
3, the screen display also uses synchronous video multimedia controller, and the various host controller card through the outer edge of the signal into data signals and synchronization signals, the use of imported high-frequency signal transmission twisted pair transmission distance, the image quality obtained high-definition good. Text message display using self-developed data acquisition card and receiving card, through the high frequency twisted pair transmission, over longer distances.
4, peripherals
Computer animation, video, playback, video cameras, laser discs, audio systems, network systems.
5 designs
Bronze aluminum frame with electronic screen new materials, decoration design and overall coordination; fixation with wall-mounted, hanging wall and floor structure.
Second, the technical parameters:
