Film structure for realizing digitization of written information on cholesteric liquid crystal handwriting board

Abstract

The invention discloses a film structure for realizing digitization of written information on a cholesteric liquid crystal handwriting board, which is characterized in that a pressure-sensitive touchstructure is arranged on the cholesteric liquid crystal handwriting board and comprises a pressure-sensitive touch electrode layer, a support column, a detection layer and a surface flexible insulating layer, the pressure-sensitive touch electrode layer is arranged on the upper surface of the shared substrate and consists of pressure-sensitive touch Sensor blocks and Tx wires which are arranged ina matrix; the upper surface of each pressure-sensitive touch sensor block is provided with protruding structures arranged in a matrix mode, and the heights of the protruding structures are arranged in a gradient descending mode from the center to the periphery. According to the cholesteric liquid crystal handwriting board, the pressure-sensitive touch layer is additionally arranged on the surfaceof the cholesteric liquid crystal handwriting board, and pressure-sensitive touch signals are converted or stored into digital signals in real time, so that the display, transmission and storage of written contents are facilitated, the use scenes of the cholesteric liquid crystal handwriting board are increased, and the cholesteric liquid crystal handwriting board becomes a new-generation electronic handwriting product.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thin film structure for realizing digitization of written information on a cholesteric liquid crystal tablet. Background technique [0002] Writing has been an important means of disseminating and recording information since ancient times. With the demand for green and environmentally friendly reusable products, cholesteric liquid crystal writing boards have begun to become a way to replace traditional paper writing. Cholesteric liquid crystal writing boards have a lower Power consumption, a variety of stable states, zero field stability, no need for additional backlight, no need for color filter polarizers, high reflectivity, thin module status, and can be written and erased many times. At present, there are many kinds of cholesteric liquid crystal tablet for people's learning and entertainment on the market, but there are important problems. First, the information of the tab...

AI Technical Summary

Problems solved by technology

At present, there are many kinds of cholesteric liquid crystal tablet for people's learning and entertainment on the market, but there are important problems. First, the information of the tablet can only be viewed by the user, and it cannot be connected to the Internet of Things to integrate with other electronic displays. The requirements for synchronous writing of equipment, and secondly, when you want to write again after a writing is completed, you must delete the previous writing content and cannot store it, which will lead to the loss of information and reduce its use efficiency
