Electronic handwriting board, application method thereof and terminal equipment

Abstract

The invention relates to an electronic handwriting board, an application method thereof and terminal equipment. The electronic handwriting board comprises: a deformable base plate; a piezoelectric film layer arranged on the deformable bottom plate layer; a bistable liquid crystal layer arranged on the piezoelectric film layer; and a transparent substrate arranged on the bistable liquid crystal layer. According to the electronic handwriting board, on one hand, the bistable liquid crystal layer is adopted to realize an electronic handwriting function; on the other hand, the piezoelectric film layer is adopted to sense and memorize the writing position under pressure, and the writing position can be memorized without a power supply state; besides, the deformable bottom plate is adopted to be matched with the piezoelectric thin film layer to achieve positioned erasing of the writing position, and therefore local clearing is achieved on the basis that all the writing positions do not need to be deleted; furthermore, the electronic handwriting board has the advantages of small size and low power consumption.

Description

technical field [0001] This application relates to the field of handwriting boards, in particular to electronic writing boards, their application methods and terminal equipment. Background technique [0002] In order to save paper and respond to environmental protection, major companies have launched electronic writing tablets, which are not only light and thin, but also highly practical and can effectively reduce the amount of paper used. The service life of an electronic tablet is about 50,000 sheets of paper. [0003] Electronic writing pads use brush strokes or pressure to deflect the liquid crystal to achieve the writing function. Electronic writing pads generally do not have the function of storage and reading. After pressing the reset button to power on, the liquid crystal returns to the original orientation, and the handwriting disappears. Electronic writing board is also called LCD writing board, LCD writing board, LCD drawing board, LCD graffiti board, etc. It is ...

Problems solved by technology

[0004] Although the electronic writing board is convenient to use, the current traditional electronic writing board has the following problems: it needs battery power, it is difficult to partially clear it, and it can only be deleted with one key
