Abstract

The invention discloses a handwriting pen of a light emitting diode (LED) dot-matrix writing display screen. The handwriting pen is wirelessly connected with a controller of the dot-matrix writing display screen through an infrared ray and comprises a pen body, a photosensitive transistor, a singlechip, an infrared emission tube and a battery, wherein the singlechip is respectively connected with the infrared emission tube, the photosensitive transistor and the battery; and the singlechip is used for processing a handwriting track signal which is input by the photosensitive transistor during the contact with an LED and controlling the infrared emission tube to emit the handwriting track signal. By changing the wired connection of the handwriting pen into the wireless connection of the handwriting pen, the LED dot-matrix writing display screen ensures that the displayed contents can be conveniently and flexibly edited and revised; and by arranging a plurality of keys on the handwriting pen, the handwriting pen can be used as an infrared remote controller and is simple in structure, low in cost and suitable for batch production.

Description

technical field [0001] The invention relates to an LED dot matrix writing display screen, in particular to a stylus for an LED dot matrix writing display screen. Background technique [0002] At present, the connection of the stylus of the LED dot-matrix writing display is a wired connection, that is, the stylus is directly connected to the controller of the display through a signal line. For example, Chinese patent application number 201010119780.3, application publication number CN101788866A, application publication date July 28, 2010, the stylus in "a kind of LED dot matrix display screen based on handwriting input" announced by the invention patent, similar literature reports even Many, its advantages are well known to everyone. However, a stylus with a wired connection is inconvenient and flexible to use. Contents of the invention [0003] The object of the present invention is to provide a stylus for LED dot-matrix writing display screen, which is wirelessly connec...
