In this study, the laser induced 10 × 10 array LEDs electronic drawing board is successfully demonstrated. The circuit lay-out contains several simple optoelectronic components, such as LEDs, photoresistors and relays. The experiment results reveal that the variable digital numbers can consequently be drawn on this electronic drawing board. Due to higher collimation of laser light, the painting can be drawn in the correct location and the long distance painting is achievable. Most importantly, this design will bring us the function of interaction on the large outdoor LEDs display; people are able to draw any pattern on it whenever we like.
