Method for Obtaining Conditions for Properly Cutting Polarizing Plates

Abstract

A method of obtaining conditions for appropriately cutting a polarizing plate according to an exemplary embodiment of the present invention may include: (a) preparing a polarizing plate including an adhesive layer and having a polarizing plate formed by cutting based on any cutting conditions; cutting the surface; (b) setting the polarizing plate so that one end of the polarizing plate abuts the guide unit; (c) moving the polarizing plate on the guide unit; (d) measuring the force applied between the polarizing plate and the guide unit while moving the polarizing plate frictional force; and (e) obtaining conditions for properly cutting the polarizing plate based on the measured value of the frictional force and adhesive leakage measurement criteria preset as information on the frictional force data.

Description

technical field [0001] The present invention relates to a method of obtaining conditions for properly cutting polarizing plates, and more particularly, to a method of obtaining conditions for properly cutting polarizing plates based on adhesive leakage measurement standards. Background technique [0002] The polarizing plate is configured to realize a desired image by polarizing light vibrating in all directions so that the light vibrates only in a specific direction. Polarizing plates are attached to both sides of the liquid crystal display (LCD) panel. [0003] Such as figure 1 As shown, the polarizing plate 100 has a layered structure including: a polarizer layer 130 made of PVA material, an upper support layer 120 attached to both surfaces of the polarizer layer 130, and a lower support layer. layer 140, a protective film layer 110 formed on the upper portion of the upper support layer 120 and configured to protect the polarizer layer 130 from external environments suc...

Problems solved by technology

However, since it is difficult to change the position of the transportation facility 1 once the transportation facility 1 is fixedly installed, leakage of only a small amount of the adhesive 151 on the transportation facility 1 also results in that the polarizing plate 100 cannot be set in the intended position for the attaching process or cleaning. the exact position of the process, resulting in a defect in the product

[0006] In the related art, a hard adhesive made by changing the composition ratio of segments contained in the adhesive is sometimes used to improve the adhesive The degree of leakage, but in this case, a problem of deterioration of adhesion caused by an increase in bulk modulus or a problem of reduced durability arises
