Description

Liquid crystal writing film structure with calligraphy and painting copybook

Technical Field

The invention relates to the technical field of liquid crystal writing films, in particular to a liquid crystal writing film structure with copybooks.

Background

Since the lcd writing display device is reusable and low in cost, more and more parents may choose to buy the lcd writing display device for children to replace the copy paper. Writing or drawing on the liquid crystal writing display device, and displaying the input effect of the original handwriting on the display screen of the intelligent terminal. The drawing board can be used for learning characters, numbers, letters and the like, can also be used for drawing various patterns (hereinafter abbreviated as simple drawing), replaces original paper drawing, and has the characteristics of convenient use and environmental protection, thus being popular with parents and children.

With the updating of electronic drawing boards for children, liquid crystal electronic writing board products are on the market successively, the working principle is that in the liquid crystal screen of the liquid crystal electronic writing board, the arrangement mode of molecules is adopted, liquid crystal can be divided into three categories of nematic type, smectic type and cholesteric type, wherein cholesteric liquid crystal is flat and arranged into layers, molecules in the layers are mutually parallel, the long axes of the molecules are parallel to the plane of the layers, the long axes of the molecules in different layers are slightly changed, and the long axes of the molecules are arranged into a spiral structure along the normal direction of the layers. The thread distance of the cholesteric liquid crystal is 300nm, the thread distance is the same magnitude as the wavelength of visible light, and the spiral distance can change along with the difference of external temperature, electric field conditions and the twisting force of the liquid crystal, because the external light can be modulated by a method of adjusting the spiral. Based on the characteristics of the liquid crystal molecular materials, handwriting board manufacturers develop liquid crystal electronic writing boards and light energy blackboards, and hopefully, the traditional electronic drawing boards for children can be replaced by scientific writing modes.

But the electronic drawing board in the field of the clinical drawings of children can lead the writing of the children on the calligraphy and painting to achieve the purpose of standardization. The Chinese patent No. 88218748.6 children's calligraphy and painting board provides a tool, which is characterized in that words and paintings are hot-pressed on a transparent plastic layer to show obvious concave lines, and then are temporarily drawn by a pen, so that the structure is inconvenient to use and cannot be used for optional calligraphy and painting, and the multifunctional drawing board with the patent No. 201420870632.9 provides a writing fun which can trace red, has bright color and convenient erasing, and improves the writing fun of children. However, because many parents and children require to preserve the picture for a long time, conveniently take away, so reform the 201420870632.9 drawing board of former patent, with the panel of the former drawing board of quick replacement, the panel damage of the drawing board of the current patent 201420870632.9 of having solved, the condemned problem of whole drawing board, but all can not satisfy the age of present informatization, both can provide a quick replacement to current drawing board liquid crystal writing membrane, also can keep the record children in-process of growing up, to the study record of calligraphy and painting, be convenient for analyze children to the study progress of calligraphy and painting.

The writing page paved with the dot matrix array wastes paper a little, but has the advantages that the writing page can be uploaded to an intelligent terminal through identifying the image information of the dot matrix array, and original handwriting, hand-painted patterns and the like written on the writing page are restored.

Therefore, after the liquid crystal writing device is connected to the intelligent terminal, the whole system only synchronizes original handwriting, hand-drawn patterns and the like from the liquid crystal writing device to the intelligent terminal. If make mistakes, can only clear up on liquid crystal writing device totally, it is really not very convenient to use like this, and intelligent terminal can't accomplish the processing function to original handwriting pattern, makes input work very inconvenient like this. And the writing page wastes paper, which is not favorable for the environmental protection idea.
