Cutting method of liquid crystal handwriting film and liquid crystal handwriting film

Abstract

The invention discloses a method for cutting a liquid crystal handwriting film. The cutting method of the liquid crystal handwriting film is to cut a whole piece of liquid crystal film into a plurality of liquid crystal handwriting films with preset sizes that are independent and separated from each other; Offset a predetermined distance around, cut off the conductive layer of the upper base film and form a cutting line on the surface of the upper base film, the cutting depth of the cutting line is less than the thickness of the upper base film. The present invention cuts off the conductive layer of the upper base film, so that the voltage of the conductive layer of the upper base film cannot reach the edge of the liquid crystal handwriting film, and solves the problem that the upper and lower conductive layers of the base film are short-circuited when the liquid crystal film is cut. The cutting depth of the film is smaller than the thickness of the upper base film, so that the liquid crystal leakage problem of the liquid crystal handwriting film is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal handwriting boards, in particular to a method for cutting a liquid crystal handwriting film and the liquid crystal handwriting film. Background technique [0002] In the field of liquid crystal handwriting films, in order to achieve handwriting effects with higher contrast and display brightness. A common practice is to increase the proportion of liquid crystals and chiral agents in the overall formulation, while reducing the proportion of polymers in the formulation. However, the reduction of the polymer content will cause the adhesion to the conductive layer of the upper and lower base films to decrease, resulting in the liquid crystal film being easily separated from the top and bottom of the liquid crystal film during the process of assembling into a liquid crystal tablet and in the subsequent use of the customer. layer status. On the other hand, due to the low polymer content sandwic...
