A Brand New Approach to LEDs Electronic Drawing Board Using Optical Illumination

Abstract

This paper presents a brand new method to Light-Emitting Diodes (LEDs) drawing board which can be induced by optical illumination. White light is used as an induced medium on this LEDs drawing board for accurate painting. Experimental results show that the white light source can successfully light up the 3×3 array LEDs drawing board. This brand new optical induced lighting technique will not only improve the disadvantage of traditional LEDs display lighted up by water, but also enhance the accuracy and feasibility of remote painting. Besides, the large outdoor interactive LEDs electronic drawing board, lighted up white light, will be expected in near future.
