Title
(EN) But liquid crystal clipboard of selective erase
(ZH) 一种可局部擦除的液晶书写板
Abstract
(EN)
The utility model discloses a but liquid crystal clipboard of selective erase, but liquid crystal clipboard of selective erase includes the conductive film, liquid crystal film, lower conductive film,go up the conductive film, liquid crystal film, down the conductive film in proper order the superpose postadhesion on the bottom plate, go up the conductive film and separate the conductive region that has the difference with lower conductive film, the conductive region is provided with extraction electrode, the module is erased in the extraction electrode connection, it is used for advancing line location and applying voltage liquid crystal film according to the region of erasing that last conductive film and lower conductive film are confirmed to erase the module, erase the writing in thecorresponding region of liquid crystal film. The utility model discloses liquid crystal clipboard selective erase method, including the step: A1, predetermine the gesture mode, A2, the last conductivefilm of confirming the gesture place of touch and the conductive region of lower conductive film, if the gesture of A3 touch accords with the gesture mode, apply voltage to liquid crystal film and last conductive film and the corresponding region of overlap area of the conductive region of conductive film down, erase the writing content in liquid crystal film and the corresponding region of overlap area.
