Abstract
The utility model provides a low-reflection polarizer which is dazzle-free, and is low in reflectivity, high in hardness, and is excellent in waterproof performance. The low-reflection polarizer includes a polarizer base material. At least one surface of the polarizer base material is coated in order with an intermediate refractive index layer with the refractive index being 1.55 to 1.70, a high refractive index layer with the refractive index being 1.85 to 2.45, and a silica film. The visible residual reflectivity of the low-reflection polarizer is lower than 0.5%, so an image can be seen clearly in strong sunlight. The low-reflection polarizer is dazzle-free, and is high in hardness and excellent in waterproof performance. The low-reflection polarizer can be widely applied to liquid crystal displays of digital cameras, digital videos, mobile phones, computers, televisions and other products to improve the display performance of the products.
Description
Technical field
The utility model relates to a kind of polaroid, especially a kind of low reflective polarizer film.
Background technology
At present, polaroid is widely used in LCD, is provided on the display screens such as digital camera and DV, mobile phone, telecomputer.Since the polaroid surface have about 4.3% reflection, this part reflected light for example can make human eye not see institute's images displayed under sunshine or the light, and eyes is easy to fatigue under strong background.Simultaneously, the outermost TAC layer of polaroid is softer, scratches easily, and water resistance is also unsatisfactory.
At present the Dereflection screen of display such as handset viewing window is the layer 2-3 antireflecting film that adopts Hydrolyze method to process at glass surface deposition of titanium oxide, earth silicon material, but Glass breadks easily, can produce injury to human body after cracked.This chemical plating method need be heated to substrate, and polaroid can be out of shape under this temperature, so even the present DV of the thousands of units of price, the surface also is not have plated film, all exist above-mentioned reflective, defective such as dazzle the eyes, be prone to scratch, non-watertight.
The utility model content
The utility model provides a kind of reflectivity low, dazzle-free, the low reflective polarizer film that hardness is high, water resistance is good.
Realize a kind of low reflective polarizer film of the utility model purpose; Comprise polarizer substrate material; On at least one surface of said polarizer substrate material, be covered with the intermediate-index layer that refractive index is 1.55-1.70 successively, refractive index is high refractive index layer and the silica coating of 1.85-2.45.
The optical thickness of said intermediate-index layer is 120-160nm, and the optical thickness of said high refractive index layer is 250320nm, and the optical thickness of said silica coating is 125-150nm.
A kind of low reflective polarizer film of the utility model is lower than 0.5% to visible residual reflectance, still can know earlier at strong sunlight and see image clearly, and is dazzle-free, hardness is high, water resistance good.Can be widely used in the LCDs of products such as digital camera, DV, mobile phone, computer, TV, improve the display performance of these products greatly.
Description of drawings
Fig. 1 is the structural representation of a kind of low reflective polarizer film of the utility model.
Embodiment
As shown in Figure 1; A kind of low reflective polarizer film of the utility model; Comprise polarizer substrate material 1, at least one surface of said polarizer substrate material 1, being covered with refractive index successively is the intermediate-index layer 2 of 1.55-1.70, and refractive index is the high refractive index layer 3 and silica coating 4 of 1.85-2.45.
The optical thickness of said intermediate-index layer 2 is 120-160nm, and the optical thickness of said high refractive index layer 3 is 250-320nm, and the optical thickness of said silica coating 4 is 125-150nm.
The material of intermediate-index layer 2 is a kind of in monox, aluminium oxide, zirconia, the cerium fluoride, and the material of high refractive index layer 3 is a kind of or its potpourri in hafnia, tantalum oxide, titanium dioxide, niobium oxide, cerium oxide, zirconia, praseodymium oxide, the lanthana.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineering technical personnel in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
Claims (2)
1. low reflective polarizer film; Comprise polarizer substrate material; It is characterized in that: at least one surface of said polarizer substrate material, be covered with the intermediate-index layer that refractive index is 1.55-1.70 successively, refractive index is high refractive index layer and the silica coating of 1.85-2.45.
2. low reflective polarizer film according to claim 1 is characterized in that: the optical thickness of said intermediate-index layer is 120-160nm, and the optical thickness of said high refractive index layer is 250-320nm, and the optical thickness of said silica coating is 125-150nm.
