Liquid crystal display having handwriting function

Abstract

The invention discloses a liquid crystal display having a handwriting function. The liquid crystal display having a handwriting function includes a main body; and the main body includes a liquid crystal handwriting film used for handwriting and a liquid crystal display used for display. The liquid crystal display having a handwriting function is reasonable in design and combines the liquid crystalhandwriting film having the handwriting function with the liquid crystal display, so that a handwriting and displaying integrated function can be realized; papers, pens and ink can be saved, and moreenvironmentally friendly can be achieved; both writing and displaying do not need electricity consumption, and micro-electricity is needed only for erasing; the liquid crystal display having a handwriting function is high in contrast, inirritative in light, clear in handwriting and high in softness; and real writing experience can be simulated by adopting pressure induction.

Description

technical field [0001] The invention relates to a liquid crystal display screen, in particular to a liquid crystal display screen with handwriting function. Background technique [0002] Liquid crystal is a liquid crystal, which is a very special substance. It flows like a liquid and has some of the optical properties of a crystal. Liquid crystal was discovered by Austrian botanist Reinitzer in 1888. It is an organic compound with regular molecular arrangement between solid and liquid. The arrangement of liquid crystal molecules has a certain order, and this order has no effect on external conditions, such as temperature, Electromagnetic fields are very sensitive to changes. Under the action of an electric field, the arrangement of liquid crystal molecules will change, thereby affecting its optical properties. This phenomenon is called the electro-optic effect. [0003] Traditional writing generally requires the use of pen, ink and paper. For example, after children use p...

Problems solved by technology

[0003] Traditional writing generally requires the use of pen, ink and paper. For example, after children use paper to practice writing and drawing, they generally discard the paper after writing, which causes a certain waste of paper and pen and ink.

With the development of science and technology, smart tablet appears on the market, but the existing smart tablet still has the following disadvantages: both writing and display need electricity, and the contrast is low, the writing clarity is low, the softness is low, and the writing experience poor

At present, the TFT display screens on the market do not have the handwriting function, and the liquid crystal film does not have the display function.
