Description
Technical field
This utility model belongs to display, the display of a kind of band LED display function.
Background technology
Multiple examination is had to achieve nonpaperlized examination at present, examination hall is that examinee specifies a computer to carry out answer, the usual way of designated computer is the numbering that the display casing to a kind of band LED display function sticks papery, examinee randomly draws numbering before examination, when setting the exam, examinee finds the computer answer of reference numeral in examination hall, and making shortcoming in this way is examinee's numbering to be extracted, time and effort consuming before examination；Information is few, it is impossible to the information such as the display name of examinee, admission card for entrance examination number；The papery numbering poor durability sticked, needed again to re-paste every a period of time, removes old numbering and is likely to cause damage display.
Utility model content
The purpose of this utility model is to provide the display of a kind of band LED display function, solves the problem in background technology.
This utility model realizes by the following technical solutions:
A kind of display of band LED display function, including LCDs housing, LED display, USB interface and switch, described LCDs lower housing portion is provided with LED display, it is provided with USB interface on the left of described LED display, it is provided with switch on the right side of described LED display, described USB interface is connected with host computer, described LED display includes controller, LED driver, LED dot matrix, battery, charging circuit, described charging circuit, battery, controller, LED driver, LED dot matrix is sequentially connected with, described battery is connected with LED driver, described USB interface is connected with controller and charging circuit respectively, described switch is connected with controller.Described controller comprises memorizer.
Beneficial effect: this utility model simple in construction, practical, shell rim at the display of a kind of band LED display function arranges a LED display, LED display is connected with host computer by USB interface, host computer controls the information such as LED display the display name of examinee, admission card for entrance examination number, it is simple to examinee is quickly found out the computer specified and takes an exam.
