An electric displaying device for utilizing a multi-scanning control process comprises: a plurality of the pixel units having basic four LEDs (green, red, blue and 2nd green); pixel drivers to control the pixel units; driver controllers to control the pixel drivers; each LED connected independently to the pixel driver and driver controller; pixel-driving cells; pixel-driving blocks; and receiving boards for accessing the image data and control signal to the pixel-driving blocks. A control process for multi-scanning on the electric displaying device comprises: multi-scan card splits and distributes the image and control signal by sections; receiver board addresses the RGB image data and control signal to the pixel-driving blocks for accessing each pixel unit; two phase signals, "phase0" and "phase1" composed with four phase stages, phase-A, -B, -C and phase-D to generate basic images and intensifying image data by overlapping neighboring LEDs; and alternating the image data and control signals through the entire screen.
