A wireless handwriting input method for led dot matrix display

Abstract

The invention relates to an LED dot-matrix display screen, in particular to a wireless handwriting input method for the LED dot-matrix display screen. According to the method, a wireless handwriting pen, a power supply of the LED dot-matrix display screen, a bicolor patch LED dot matrix with the row-column specification of 16*15, a single-chip microcomputer, a key switch and an infrared receiving head are structurally adopted; the single-chip microcomputer is respectively connected with the bicolor patch LED dot matrix with the row-column specification of 16*15, the key switch, the infrared receiving head and the power supply; the power supply is further respectively connected with the bicolor patch LED dot matrix with the row-column specification of 16*15, the key switch and the infrared receiving head; the handwriting pen is in wireless connection with the LED dot-matrix display screen. Wireless handwriting input of the LED dot-matrix display screen can be achieved, the wireless handwriting input for the LED dot-matrix display screen is convenient and flexible, and the application range can be expanded.
