AI Technical Summary

Problems solved by technology

In addition, during the manufacturing process of the polarizing film, slight deformation or damage on the PVA film layer may cause light leakage (クニック)
When the LCD screen is driven with light leakage or scratches on the polarizing film, fatal defects such as spots on the screen may occur.

Abstract

The related film carrier for polarized light (100) comprises: a base clamp part (110) on base (1) side and with a fixing plate (111) and at least one clamper (10), a first clamp part (120) on another side of base, the second and the third clamp part (130, 140) on back and front of the base, wherein the four clamp parts hold the film two sides, front and back ends respectively.

Description

technical field [0001] The present invention relates to a polarizing film carrier, and more particularly, to a polarizing film carrier which can hold and transfer the polarizing film while maintaining the flatness of the polarizing film at each work position when inspecting a polarizing film suitable for LCD. Background technique [0002] Polarizing films suitable for LCD (Liquid Crystal Display) include iodine, dye, retardation, semi-transmission and reflection types. Among them, the iodine-based polarizing film is used as a high-definition LCD polarizing film with high transmittance and high polarization characteristics, and iodine is used in a transparent PVA (Poly Vinyl Alcohol) film, so that it can absorb light in the visible light region. [0003] The structure of the above-mentioned polarizing film is generally composed of a TAC (Tri-Acetyl-Cellulose triacetyl cellulose) film, an adhesive, a polarizing element, an adhesive and a TAC film that are sequentially laminate...
