Abstract:
1. An electric displaying device for utilizing a multi-scanning control process is assembled with a plurality of Light Emitting Diode (LED) modules, which are preassembled a plurality of sectional basic LED panels, the electric displaying device comprising: a plurality of pixel units consisting of at least three basic LEDs with three primary colors on the sectional basic LED panels, a plurality of pixel drivers for controlling corresponding basic LEDs of the pixel units on the sectional basic LED panels, a plurality of driver controllers for controlling corresponding pixel drivers on the LED modules, a plurality of pixel-driving cells fabricated with the plurality of pixel drivers and driver controllers for controlling the LED module as a whole unit, so that the pixel units disposed along with borders of the sectional basic LED panels assembled in the LED module are controlled as same as a single basic panel, a plurality of pixel-driving blocks fabricated with the plurality of pixel-driving cells for controlling the assembly of the LED modules as a whole unit, so that the pixel units disposed along with borders of the assembled LED modules are controlled as same as a single basic panel, a plurality of receiving boards for providing the RGB image data and control signal to corresponding pixel drivers, said control signal comprising at least one phase signal as well as synchronizing signal, and said RGB image data comprising at least two pixel data groups corresponding at least two phase stages, a multi-scan card for processing said RGB image data and control signal in response to each phase signal at corresponding phase stage to display on corresponding sections of displaying device, in rows, in columns, or in rows and columns, wherein said control signal is formed by two phase signals “phase displayed RGB image data is composed with basic image data generated by basic LEDs of pixel units and intensified image data generated by overlapping the LEDs between neighboring pixel units.
