Abstract
The utility model provides a demonstrating apparatus of an LED (light emitting diode) display screen and relates to a display device in large occasion, belonging to a teaching apparatus. The demonstrating apparatus of the LED display screen consists of the LED display screen, wherein the dot matrix of the LED display screen is larger than 64*128, and the color of the LED display screen is bi-color or tri-color; the LED display screen is controlled by a control plate, the control plate consists of a singlechip, a memorizer and a gating circuit, and the singlechip receives a control program from the memorizer and controls the display of the LED display screen by the gating circuit; the LED display screen and the control plate are arranged in a suitcase type shell, and the shell is further internally provided with a power source which supplies the power for the LED display screen and the control plate; and the shell is designed with 4-16 control buttons which are connected with an I/O (input/output) port of the singlechip. The demonstrating apparatus can pre-memorize a plurality of demonstrating cartoons, is also convenient to update and load the demonstrating content, can select and control the playing content due to arrangement of the control buttons, and more importantly, is light and firm in LED display screen, suitable for the display in large occasion, and can be repeatedly played.
Description
Technical field
The LED display demonstrator belongs to instruments used for education, relates to a kind of big occasion display device.
Background technology
Nowadays LED display is widely used as the display media of large-scale occasion, arranges as the scene of the large display screen of open air, rolling advertisement, the 25th Olympic Games.LED display has following advantage as the display media of large-scale occasion:
1. bright in luster, color is enriched, brightness is high.
2. show that dot matrix can conveniently expand.
3. durable, adaptive capacity to environment is strong, the life-span is long.
4. cheap, cost of installation and use is low.
Physics is the subject of a gated image, and in college physics teaching, the explanation that needs image to show to the student.There is multiple media format to demonstrate physical image in the physics teaching, as with hall lecture experiment, Flash, wall chart etc.From the characteristics of above-mentioned LED display as can be seen, LED display also can be used as a kind of medium of demonstration physical image fully.LED display is durable, and is bright in luster, and be fit to big occasion and watch, and can be by the various phenomenons of programming demonstration.So be made into a kind of portable, programmable demonstration medium with LED display, can be used as the good assistant of classroom instruction.
Summary of the invention
The purpose of this utility model provides a kind of demonstrator that utilizes LED display to make, and controls, is fit to the display device that teaching demonstration that lyceum plays is used as a kind ofly being convenient for carrying, being convenient to.
To achieve these goals, the LED display demonstrator of the utility model design is made up of LED display, and the dot matrix of LED display is greater than 64 * 128, and the color of LED display is double-colored or three looks; LED display is controlled by control panel, and this control panel is made up of single-chip microcomputer, storer, gating circuit, and single-chip microcomputer is from the storer receiving control program, and the demonstration by gating circuit control LED display; LED display and control panel are contained in the shell of portable case type, and the power supply to LED display and control panel power supply also is housed in the shell; And 4～16 control knobs are housed on shell, and this control knob connects the I/O mouth of single-chip microcomputer.And described control panel is provided with the external receptacle to memory loader.
The major advantage of this device is: this demonstrator a plurality of Show Me animations that can prestore, also conveniently upgrade and install demo content additional; And control button, can select and the controls playing content; The more important thing is that LED display is lightly solid, be fit to the demonstration of big occasion, and can repeat playing.
Description of drawings
Fig. 1 is a preferred embodiment profile synoptic diagram of LED display demonstrator.
Among the figure: the 1-LED display screen; The 2-shell; The 3-button; The 4-handle.
Embodiment
Below in conjunction with preferred embodiment shown in Figure 1 the utility model is described further and operation instruction.
As shown in Figure 1, LED display 1 in the present embodiment is made up of 2 * 2 LED display modules, each LED display module is made of 4 * 8 LED display unit, LED display unit wherein is the LED lamp of 8 * 8 dot matrix, and each LED lamp is made up of red light emitting diodes and green LED.The LED lamp is lighted by chip for driving, and as chip for driving, 74HC595 has 8 bit shift register and a storer to the LED display module in the present embodiment with 74HC595.The LED chip for driving is controlled by control panel, and control panel generally is made up of single-chip microcomputer and gating circuit.The chip for driving and the interface that is connected with control panel that have comprised the LED display unit in the LED display module.
Because the dot matrix of display screen is huge, generally simultaneously all dot matrix of control display screen bright, go out, can only control one be listed as the LED lamp bright, go out, so certain picture is in a flash lighted respectively, scanned and form by each row.In single-chip microcomputer, import demonstration program, single-chip microcomputer according to demonstration program control LED bright, go out, just formed can the display simulation phenomenon demonstrator.
Four LED display module spliced are contained in the shell 2, and shell 2 top center are provided with handle 4.Backboard is established in shell 2 back.Control panel and give LED display and the power supply of control panel power supply is placed in the shell 2.The side that takes at the top of shell 2 is provided with eight buttons 3, and these buttons are connected with control panel, as the external interrupt of control program, can select and controls the demonstrator displaying contents.
Claims (2)
1.LED the display screen demonstrator is made up of LED display, it is characterized in that: the dot matrix of LED display is greater than 64 * 128, and the color of LED display is double-colored or three looks; LED display is controlled by control panel, and this control panel is made up of single-chip microcomputer, storer, gating circuit, and single-chip microcomputer is from the storer receiving control program, and the demonstration by gating circuit control LED display; LED display and control panel are contained in the shell of portable case type, and the power supply to LED display and control panel power supply also is housed in the shell; And 4～16 control knobs are housed on shell, and this control knob connects the I/O mouth of single-chip microcomputer.
