preparation example

[0056] A haze coating is prepared from the following raw materials in parts by weight: 38.85 parts of an organic solvent, 60 parts of a UV curing agent, 0.15 parts of an auxiliary agent, and 1 part of microparticles.

[0057] Among them, the organic solvent is selected from butyl acetate; the UV curing agent is selected from UV-3621; the auxiliary agent is selected from the leveling agent YCK1310; the particles are polystyrene particles, polymethyl methacrylate particles, and polystyrene particles, poly The weight ratio of the methyl methacrylate particles is 1:1, the D80 particle size of the polystyrene particles is 3.5 μm, and the D80 particle size of the polymethyl methacrylate particles is 1.8 μm. Polystyrene particles are selected from Dongguan Hongyu Plastic Chemical Technology Co., Ltd.; polymethyl methacrylate particles are selected from Yuyao Kaige Plastic Chemical Co., Ltd.

Embodiment 1

[0062] A kind of processing technology of retardation polarizer, it comprises the steps:

[0063] S1. Apply a haze coating on the light exit surface of the phase retarder 3. The haze coating is obtained by using the preparation example. The phase retarder 3 is Teijin RM-147. The haze coating is cured to form a haze coating 31. The haze coating The thickness of 31 was 5 μm, and the phase retarder 3 with the haze coating 31 was obtained, and the haze of the haze coating 31 was 9.53%.

[0064] S2. Coating the bonding layer material on both sides of the polarizer body 11. The polarizer body 11 is a polyvinyl alcohol film, and the bonding layer material is PVA glue, which is selected from Mitsubishi Chemical Corporation. Then, the inner protection layer 12 is provided on the light incident side of the polarizer body 11 and on the bonding layer material, and at the same time, the phase retarder 3 is arranged on the light emitting side of the polarizer body 11 and on the bonding laye...

Embodiment 2

[0067] The difference between this embodiment and Embodiment 1 is that the phase retarder 3 is Konica Minolta KC2UGR.

Abstract

The invention relates to the technical field of polaroid processing, and particularly discloses a phase delay polaroid, a processing technology thereof and an optical display device. The phase delay polaroid comprises a linear polaroid, a phase delay piece arranged on the light emergent surface of the linear polaroid and a haze coating arranged on the surface, away from the linear polaroid, of the phase delay piece. The haze of the haze coating is 1-50 percent; the phase delay piece has a retardation amount of 95-220 nm under a wavelength of 550 nm; and the linear polaroid is fixedly connected with the phase delay piece through a bonding layer I. According to the phase delay polaroid, through mutual cooperation of the linear polaroid, the phase delay piece and the haze coating, a user wearing polarized sunglasses can see pictures on a display screen clearly, and meanwhile reflection glare of a bright light source is relieved.

Description

technical field [0001] The present application relates to the technical field of polarizer processing, more specifically, it relates to a phase retardation polarizer, its processing technology and an optical display device. Background technique [0002] Polarizers are also called polarizers. The imaging of liquid crystal displays must rely on polarized light. All liquid crystal displays have two linear polarizers attached to the liquid crystal glass, forming a liquid crystal sheet with a total thickness of about 1mm. When the display is used outdoors, users who wear polarized sunglasses sometimes cannot see the images on the display, which affects the normal use of the display. In addition, under bright light sources, the display often reflects bright light. glare, which affects the realistic contrast of the display. Contents of the invention [0003] In order to enable users wearing polarized sunglasses to see the picture on the display screen while reducing the reflecte...
