Description

Multifunctional handwriting device

[ technical field ] A method for producing a semiconductor device

The utility model relates to a handwriting board, in particular to a multifunctional handwriting device.

[ background of the utility model ]

In a conventional writing mode, a pen is usually used to write contents on a paper carrier for recording, such as drawing, note taking and the like. The writing mode using the paper carrier has free writing and good hand feeling, but the content is not easy to store, and is particularly not favorable for storing into an electronic format. For the written content written on the paper carrier, if the written content is to be stored in an electronic format, the written content is usually photographed and stored in a picture format, and the storage can only store the content as a whole, but is not beneficial to extracting the written content to edit and apply the written content again.

With the progress of science and technology, people gradually use electronic writing to replace paper writing. It has different advantages and disadvantages for different electronic writing media. Common electronic writing media mainly comprise an electromagnetic screen, a resistance screen, a capacitance screen and a cholesteric liquid crystal handwriting screen.

The electromagnetic screen and the cholesteric liquid crystal handwriting screen have lower cost and are widely applied to the field of handwriting and recording or drawing at present. For the electromagnetic screen, the position information of the electromagnetic pen is acquired mainly through electromagnetic induction between the electromagnetic pen and the electromagnetic screen, and writing handwriting is formed through calculation. The electromagnetic screen cannot present the handwriting in real time, so that the handwriting is not visual enough, but the handwriting of the electromagnetic pen can be acquired and displayed on a display terminal, such as a computer display, so that the electromagnetic screen is widely applied to a hand drawing board and is mainly used for drawing collection line drawings. The cholesteric liquid crystal handwriting board is low in power consumption, can present writing handwriting due to pressure, and can present the writing handwriting in real time, but the writing handwriting can not be extracted into electronic data to be stored and can not be further applied on the basis because the presentation of the writing handwriting is realized by the pressure sensed by the cholesteric liquid crystal.

Therefore, the existing electronic writing medium is high in cost, cannot display the writing handwriting in real time, is not visual enough to write, or cannot extract the writing handwriting to store or further apply.
