Superhigh resolution trace-type cholester liquid crystal writing input display screen

Abstract

The present invention refers to the principle, structure and manufacturing method for ultrahigh resolution trace remaining type cholest - liquid crystal calligraph inputted display screen. Said calligraph function is realized by mechanical force (i.e. penpoint pressure) and utilizing electric field force erasing written information; said input function is realized by mechanical force to make two substrates electrode short circuit, thereby to make equivalent circuit information with two-dimensional space co-ordinate to generate corresponded relation. Said Ultrahigh resolution property is generated by ultraviolet light tactic polymerization to form micro-liquid crystal cell structure under light hood function.

Description

Technical field: [0001] The invention relates to the principle, structure and manufacturing method of a display screen for ultra-high resolution cholesteric liquid crystal writing input. The system uses the cholesteric liquid crystal box to realize the dual functions of writing and input under the action of mechanical force and electric field force. The realization of the writing function is written by mechanical force (that is, the pressure of the pen tip), and the written information is erased by the electric field force; the realization of the input function is to short-circuit the electrodes of the two substrates by the action of the mechanical force, thereby Make the information of the equivalent circuit correspond to the two-dimensional space coordinates. The characteristic of ultra-high resolution is produced by directional polymerization of ultraviolet light under the action of a photomask to form a micro liquid crystal cell structure.

AI Technical Summary

Problems solved by technology

[0008] One is that the strength of the network micro-domain structure is low, and it cannot effectively prevent the flow of liquid crystals. While writing, the network structure is also prone to damage;

[0009] The second is that there are still some monomer residues of the polymer in the liquid crystal phase after phase separation, which leads to a decrease in display quality, such as a decrease in brightness and contrast.

[0010] The third is that the network micro-domain structure randomly separates the upper and lower substrates, making it difficult for the upper and lower substrates to cause a short circuit effect between the local substrates under the action of the pen tip, making it difficult to create a device that integrates writing, input and display. new liquid crystal writing device

This structure of separating "writing" (visual recording) from input (information transmission) can no longer meet the needs of input components of portable electronic devices and paperless office equipment.
