Abstract
The invention relates to an LED dot matrix display screen based on handwritten input comprising an LED dot matrix display screen, a stylus pen and a controller, and is characterized in that the LED dot matrix display screen is connected with the stylus pen, the stylus pen is connected with the controller, and the controller is connected with the LED dot matrix display screen. The invention has the advantages that: (1) a personal computer (PC) and a dot matrix code conversion software are not needed, the system is simple, and the cost is lower; (2) the stylus pen can be used for randomly writing patterns, characters and symbols to be displayed on the dot matrix display screen, and dot matrix codes do not need to be considered, thereby being flexible and convenient in use; and (3) the LED dot matrix display screen has small volume, can be conveniently carried and is very suitable for occasions such as vocal concerts, sports events, parades, meetings.
Description
Technical field
The present invention relates to a kind of LED dot matrix display screen, relate in particular to a kind of LED dot matrix display screen based on handwriting input.
Background technology
LED (Iight emitting diode, light emitting diode) dot matrix display screen be a kind of by control semiconductor light-emitting-diode carry out device shown, form by a lot of light emitting diodes, come character display by light emitting diode luminous, can be used for information such as display text, figure, symbol.
In current society, the LED dot matrix display screen is widely used, and its quantity of information big with its display area, that show is abundant, dynamic display mode, dazzle the favor that beautiful advantages such as display effect have been subjected to people.At present, the LED dot matrix display screen has all obtained a large amount of uses in bank, station, airport, enterprises and institutions and individual shop, but also has broad application prospects.
At present, traditional LED dot matrix display screen display packing person of being to use need install the coding conversion software that the manufacturer provides at PC earlier, input need be wanted content displayed at the LED dot matrix display screen on this software, and change into specific dot matrix coding, serial ports by PC or USB interface send these codings the controller of LED dot matrix display screen to then, then by the demonstration of controller control LED dot matrix display screen.This display packing operation is fairly simple, easy to use, but the drawback that has some to be difficult to overcome: 1, this display packing had both comprised LED dot matrix display screen and corresponding controller, also comprise PC software, cost is higher, process is also a bit complicated, needs the user to possess certain computer level; 2, to all need on PC, import and change into corresponding dot matrix coding in LED dot matrix display screen content displayed at every turn, but the character that some is specific, be difficult to corresponding dot matrix coding, therefore be difficult on the LED dot matrix display screen and show, so this method relative complex and underaction; 3, because the conversion process of coding needs PC to assist to finish related work, so portable relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of LED dot matrix display screen based on handwriting input, the user wants content displayed by only needing use mobile writing pencil on the LED dot matrix display screen to write, controller just can control writing pencil the LED in zone of process luminous, thereby finish corresponding demonstration.
The present invention is achieved in that it comprises LED dot matrix display screen, writing pencil, controller, it is characterized in that the LED dot matrix display screen connects writing pencil, and writing pencil connects controller, and controller connects the LED dot matrix display screen.
There are some LED on described LED dot matrix display screen surface.
Described writing pencil is made up of photoresistance, handwriting and signal wire, and an end of handwriting connects photoresistance, and the other end of handwriting connects signal wire.
Described controller is made up of box body, battery, input interface, microprocessor, button, output interface, box side wall is connected with output interface and input interface respectively, input interface connects microprocessor, microprocessor connects battery, output interface and some buttons, and some buttons are fixed on the controller surface.
Technique effect of the present invention is: 1, do not need PC and dot matrix code conversion software, system is simple, and cost is lower; 2, writing pencil can be write figure, literal and the symbol that needs demonstration arbitrarily on the dot matrix screen, and do not need to be concerned about its dot matrix coding, flexible and convenient to use, 3, volume is little, be easy to carry, be highly suitable for occasions such as concert, competitive sports, parade, rally and use.
