Multi-scanning control process and LED displaying device

Abstract

An electric displaying device for utilizing a multi-scanning control process comprises: a plurality of pixel units, each pixel unit consisting of four LEDs (green, red, blue and 2nd green); a series of pixel drivers for controlling the corresponding LEDs of pixel units; a series of driver controllers to control corresponding pixel drivers, each LED being independently connected to the corresponding pixel driver and driver controller; a series of pixel-driving cells fabricated from the pixel drivers and driver controllers; pixel-driving blocks fabricated from the pixel-driving cells; receiving boards for accessing the image data and control signal to the corresponding pixel-driving blocks. The control signal is formed during two phases, phase0 and phase1, with four phase stages, Phase-A, Phase-B, Phase-C and Phase-D, to generate four different control signals for overlapping neighboring LEDs. A control process for multi-scanning on an electric displaying device, the process comprising the steps: multi scan card splits and distributes the image and control signal by sections; receiver board addresses the RGB image data and control signal to corresponding pixel-driving blocks; image data and control signals access each corresponding pixel unit; two phase signals, phase0 and phase1 composed with four phase stages, Phase-A, Phase-B, Phase-C and Phase-D to generate basic image and intensifying image data generated by overlapping neighboring LEDs; and the basic image data and intensified image data are composed and alternated by the corresponding image data and control signals through the entire screen.
