Embodiment 1

[0036] Raw materials: protective film, COP micro-retardation film with AG coating on the surface, PVA film, inner protective TAC film, peeling film

[0037] Adhesives: PVA glue, pressure sensitive adhesive.

[0038] Use PVA glue to compound the COP micro-retardation film and the inner protective TAC film on both sides of the dyed and stretched PVA film, and use pressure-sensitive adhesive to compound the peeling film on the other side of the inner protective TAC film. One side of the film is compounded with a protective film.

Abstract

The invention discloses a thin integrated 3D three-dimensional display polarizer and a preparation method thereof. In the protective film layer, the slow axis of the even-numbered lines of the micro-retardation film and the transmitted optical axis of the polyvinyl alcohol film layer are 0° to 50° or 130° to 180°, and the slow axis of the odd-numbered lines of the micro-retardation film and the polyethylene The transmission optical axis of the alcohol film layer is arranged at an angle of 130°-180° or 0°-50°, and the micro-retardation film is treated with anti-glare AG, anti-reflection AR / LR or anti-scratch HC. The polarizer of the present invention can convert the linearly polarized light emitted by the liquid crystal display panel into two sets of independent, intersecting left and right circularly polarized lights to form left and right images, and the audience only needs to wear simple and cheap circularly polarized glasses to watch the colors Pure, flicker-free 3D display images, and the polarizer of the present invention has thin thickness and high optical transmittance.

Description

technical field [0001] The invention relates to a polarizer for a TFT liquid crystal display, more precisely, a 3D three-dimensional display polarizer with thinner thickness and higher light transmittance. The invention also relates to a preparation method of the polarizer. Background technique [0002] At present, the polarizers on the market can only produce one kind of polarization characteristics, and cannot directly make the general TFT liquid crystal display show a three-dimensional display effect. The peeling film, the original polarizer and the three-dimensional display film, the three-dimensional display film is mainly a micro-retardation film, the thickness of this polarizer is thicker, and the optical transmittance is lower. The disclosed preparation method includes three steps. Step 1: Install the rolled original polarizer bonded with two layers of peeling film on the first unwinding device in a relatively rotatable manner, and install the rolled three-dimensio...
