Show electromagnetic hand-writing pen 210.
Wherein, power key 201 is used for the control of the electric power on/off of electrical screen, when the power supply of electrical screen is closed
When, power supply indicator does not work, during in opening, and power supply indicator is bright and is green, when power supply indicator is bright, but is yellow
When, represent that electrical screen needs charging, moreover it is possible to use 30 minutes.Power key 201 is the electricity of electromagnetism pressure sensitivity plate 103 and controller 104
Source switch, long-press preset time period can carry out the switching of opening and closing state, such as long-press 4 seconds.
Further, when the writing panel of electrical screen reaches that preset time period does not work, do not work within such as 2 minutes, then automatically
Power supply is closed, power consumption is saved.Also, when power key 201 is closed, electromagnetism pressure sensitivity plate 104 and controller 105 not work
Make, it is impossible to preserve and upload written contents.
Clear key 202 can remove written handwriting, specifically, when power key 201 is closed, only flexible hydraulic
Crystalline substance screen 101 is in work, and when clear key 202 is pressed, trigger controller 104 can enter to the person's handwriting above flexible liquid crystal screen 101
Row cls.When power key 201 is in opening, electromagnetism pressure sensitivity plate 103 and controller 104 press clear key also in work
202, trigger controller 104 is removed simultaneously to the written information of flexible liquid crystal screen 101 and electromagnetism pressure sensitivity plate 104.
When preservation key 203 is pressed, handwriting trace information is preserved, specifically, opening is in power key 201
When, pressing preserves key 203, can trigger controller 104 and preserves the trace information that the electromagnetic hand-writing pen writes picture in electrical screen
Into memory module 105, preserve the surrounding of key 203 or can be positioned below preservation indicator lamp, the preservation indicator lamp is bright and shows
Green, expression is preserved successfully.Meanwhile, controller 104 is to flexible liquid crystal screen 101 and the cls of electromagnetism pressure sensitivity plate 103.When preservation key
After 203 are pressed, when memory module 105 is without enough memory spaces, the preservation indicator lamp is bright and shows in addition to green
Other colors, for example, show yellow, then it represents that failure is preserved, while trigger controller 104 is to flexible liquid crystal screen 101 and electromagnetism pressure
Feel the cls of plate 103, now, only flexible liquid crystal screen 101 works, and normally shows written handwriting.
It is pressed when uploading key 204, when power key 201 is in opening, the electromagnetic hand-writing pen writes the person's handwriting letter of picture
Breath uploads to the terminal by WIFI module by controller 104 through wireless network, and the terminal includes：The terminal devices such as computer, mobile phone,
Corresponding driver is installed on the terminal to handle the handwriting information, if uploading the indicator lamp for successfully uploading key 204
Bright and shown in green, if upload is unsuccessful, the indicator lamp of upload key 204 is bright and is shown as yellow, and wait is transmitted again
Or resume, if upload three times it is unsuccessful, the control memory module 105 of trigger controller 104 preserves the handwriting informations, if without depositing
Space is stored up, then directly flexible liquid crystal screen 101 and the cls of electromagnetism pressure sensitivity plate 103, or, prompting user can not be stored, be selected by user
Select and whether continue to upload, or cls is performed to flexible liquid crystal screen 101 and electromagnetism pressure sensitivity plate 103.
Auxiliary key has 5：A/1 keys 205, B/2 keys 206, C/3 keys 207, D/4 keys 208, additional character key 209, special symbol
Number key can be any punctuation mark key, in the present embodiment with comma () key exemplified by, i.e. ", " key in Fig. 2.For example, selecting
During topic, first by clear key 202, then A/1 keys 205, comma key 209, B/2 keys 206 are pressed, finally press upload key 204, expression is somebody's turn to do
The answer of multiple-choice question is " A " and " B " two options, and other selection operations are by that analogy.First by clear key when doing non-selection topic
202, then A/1 keys 205, B/2 keys 206 are pressed, represent to do the topic that question number is A2, will can answer content and A2 when pressing upload key 204
Topic is accordingly filled at the answer of A2 topics, and other operations are by that analogy.By clear key 204 when needing to reform, re-start
Operate, can not be modified after uploading answering information above.
