Column scan drive circuit 2 is finished following work: receive scanning impulse, each one step of pulse automatic shift, promptly export useful signal and move on to L+1 from L; Provide N capable at the luminous required electric current of the LED that originally lists;

Line-scanning drive circuit 3 is finished following work: receive and latch the video data from microcomputer controller 1; Each row provides a LED to show required electric current;

Activation signal testing circuit 5 is finished following work: can accurately discern high/low level, be low level when the pen contact is arranged, and do not have pen and connect and be high level; Receive the reading order of microcomputer controller 1, timesharing provides the detection data to data/address bus;

In Fig. 2: be provided with display window 6, function button 7, socket 8 and display plane 9 on the guidance panel 11 of the present utility model, the mode that display plane 9 is arranged by matrix by light emitting diode 10 is formed.

In Fig. 3, the top of light emitting diode 10 is a light penetrating object 13, is provided with metallic conductor 12 at position, light penetrating object center, and the diameter of this metallic conductor 12 is less than 0.4 millimeter, and this metallic conductor 12 is connected with the anodal pin electricity of light emitting diode 10.

In Fig. 4, metal pen is made of nib 18, insulation penholder 17, plug 15 and lead 16, and metal nib 18 is arranged on the front end of penholder 17, is provided with lead 16 in the insulation penholder 17, and an end and the metal nib 18 of lead 16 are joined, and its other end and plug 15 join.

In Fig. 5, the operation principle of each circuit part of the present utility model is as follows:

Bridge rectifier B1, capacitor C 1, C2, voltage regulation unit 7805, capacitor C 4, isolating diode D1 consists of power circuit; 9 volts of alternating currents that the external power supply transformator provides are introduced by plug P2, and plug P3 connects accumulator, can use storage battery power supply in the occasion of no civil power.

Microcomputer controller 1 comprises central processing unit U1, and capacitor C 4, C5 and crystal HZ are oscillator section; Resistance R 10～R13 and 4 buttons constitute the order importation, read key value under the control of working procedure in real time; Memorizer U2, resistance R 8, R9 are in order to preserve graph data, and plug P1 is used for connecting external memory storage, reads/store data by (23/24) two line of CPU under the control of working procedure, changes this memorizer and can show many arbitrarily figures; Video data latch U3, current-limiting resistance R1～R7 and eight sections charactrons constitute display circuit, and numeral is presented at the control of software down by (16/17) two line switching of CPU, finishes dynamic scan, and described working procedure adopts the assembler language establishment.

Row dynamic scan drive circuit 2 is by shift register U12～U14, audion V8～V32, and resistance R H1～RH24 forms, and the size that changes display screen can increase or reduce corresponding number and realize; The output pin of resistance R H1～RH24 and U12～U14 is linked in sequence, under the control of software, keep having only in 24 output pins one effective (is effectively at low level state) to send out the CLK that shift register is arrived in a rising pulse by CPU (25) every the regular hour, row output effective status moves to right one, finishes the one scan circulation per 24 times; The colelctor electrode of audion V8～V32 links to each other with the respective column current-limiting resistance (R) that shows diode, has only when driving the audion conducting of these row, and the possibility of lighting is just arranged at this light emitting diode that lists.

Line-scanning drive circuit 3 is made up of data latches U4～U7 and divider resistance RF1～R32, and resistance R F1～RF32 links to each other with the corresponding output lead of latch; Under the control of working procedure, send latch pulse in proper order by (19/20/21/22) four line of CPU and deposit the required data presented of effective display column in latch in order, when certain position was output as low level, then the light emitting diode that links to each other with this was bright; Under the control of working procedure, constantly also export this simultaneously lists required data presented to scan columns, just can demonstrate various figures like this.

Activation signal testing circuit 5: U8～U11 forms by buffer, and its input line links to each other with RF1～RF32; Under the control of working procedure, in proper order the RF1 on the current display column～RF32 level state is read into CPU by (27/28/29/30) four line of CPU,

Is high level when lighting light emitting diode 10 anodal when the voltage on the divider resistance RF then reads in greater than 2 volts when not contacting, when pen contacts with light emitting diode 10 positive poles of lighting, because metal penpoint 18 links to each other with ground wire, at this moment line output is a low level again, and the level that reads in so then is low level.Working procedure just can determine that by judging the light emitting diode 10 which is lighted links to each other with pen, with regard to controlling this lamp is extinguished like this, repeats such process and just can finish and a little put out a width of cloth picture or make width of cloth picture.
