The invention discloses a locally erasable liquid crystal membrane with a through hole design and a locally erasable liquid crystal writing device with the through hole design. The liquid crystal membrane comprises a first conductive layer, a second conductive layer, a liquid crystal layer, a first base material layer and a second base material layer, wherein the liquid crystal layer is arranged between the first conductive layer and the second conductive layer; the second conductive layer is formed on a surface of the second base material layer, an electrode is led out from the second conductive layer, and the electrode inputs a second voltage signal into the second conductive layer; the first conductive layer and the first base material layer are respectively segmented into a plurality of mutually independent first conductive blocks and a plurality of mutually independent first base material square blocks, the first conductive blocks are formed on surfaces of the first base materialsquare blocks in one-to-one correspondence, a central position of each base material square block is provided with a through hole, and the through hole is filled with conductive materials. An electricfield is formed between the first conductive block and the second conductive block, writing marks of an area, relatively covered by the electric field, of the liquid crystal layer is erased, and thus, a local erasing function is realized.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a partially erasable liquid crystal membrane with a through hole design and a liquid crystal writing device. Background technique [0002] The working principle of the liquid crystal writing device is that when objects with certain hardness, such as fingernails and pens, are used to write on the liquid crystal display material, the liquid crystal is partially displaced at the writing position, which changes the molecular arrangement structure of the liquid crystal and makes the writing strokes display. However, when liquid crystal writing devices on the market erase written content or drawing content, they usually erase the entire screen and cannot realize the function of partial erasing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a partially erasable liquid crystal diaphragm with a through hole d...
