Liquid crystal writing film and evaporation process-based liquid crystal writing film processing method

Abstract

The invention discloses a liquid crystal writing film and an evaporation process-based liquid crystal writing film processing method. The liquid crystal writing film comprises an upper film substratelayer, an upper film conductive layer, a liquid crystal molecule layer, a lower film conductive layer and a lower film substrate layer which are sequentially arranged, wherein the upper film conductive layer and the lower film conductive layer are partitioned into a plurality of mutually-insulated conductive regions, an overlapped region of the conductive region of the upper film conductive layerand the conductive region of the lower film conductive layer in space and the liquid crystal molecule layer region corresponding to the overlapped region jointly form an erasure region, an electrode is led out of each conductive region and is electrically connected with a control circuit of the liquid crystal writing film, and voltages are respectively applied to the conductive region of the upperfilm conductive film and the conductive region of the lower film conductive layer, electric field superposition is formed for each erasure region, local erasure is achieved by different pressure difference formed in each erasure region, easy wiping and easy writing can be achieved, and the writing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal writing film and a processing method for the liquid crystal writing film based on an evaporation process. Background technique [0002] In recent years, with the breakthrough of liquid crystal tablet technology and the continuous decline of cost, liquid crystal tablet has been widely used in various industries. For this type of liquid crystal tablet with liquid crystal material as the display carrier, users only need to use the supporting writing pen (or even fingernails) to realize free writing on the LCD tablet. The dust-free, ink-free and fast erasing features of the LCD tablet are also well received by users. However, most of the current liquid crystal writing boards cannot realize partial erasing, and if a writing error occurs accidentally, all of them will be erased, which makes the partial erasing function particularly important.
