Problems solved by technology

As a high barrier film, the film facing liquid crystal display must have a total light transmittance of more than 90%, and Haze and b* must be below 1. However, for high barrier films, it is very difficult to achieve ideal optical effects

Embodiment

[0014] Example: refer to figure 1 As shown, the high transmission optical barrier film provided by the present invention is composed of a PET optical film 2 and a SiO coating 1 evenly attached to both sides of the PET optical film.

[0015] The specific thickness of the SiO coating 1 in this implementation is chosen to be 85-90 nm.

[0016] In this example, a SiO coating 1 is attached to the surface of the PET optical film 2. The SiO coating 1 has the functions of the original high barrier film (water and oxygen barrier) and anti-reflection (AR) coating, so that the product of the present invention has both High barrier performance, but also has good anti-reflection performance. The specific performance improvements are as follows:

[0017] 1. Because of the SiO coating 1 attached to both sides of the PET optical film 2, the overall barrier performance of the film of the present invention reaches 10 -1 -10-3g / ㎡ / day.

[0018] Because the SiO coating 1 is atta...

Abstract

The invention discloses a high-permeation type optical barrier film. The high-permeation type optical barrier film comprises a PET optical film, and is characterized by further comprising an SiO coating uniformly attached to the two surfaces of the PET optical film. According to the invention, the SiO coating is attached to the surface of the PET optical film and the SiO coating has the functions of an original high-barrier film and an antireflection (AR) coating so that the product provided by the invention is enabled to have both high obstruction performance and also good antireflection performance. The overall obstruction performance of the film provided by the invention reaches 10<-1> to 10<-3>g / m<2> / day, at the same time, the reflectivity is further reduced, the light transmittance is greatly enhanced, and the full-light transmittance can reach more than 94%.

Description

technical field [0001] The invention belongs to the technical field of optical component structure improvement, and in particular relates to a high-transmittance optical barrier film. Background technique [0002] The LCD panel itself does not emit light, but uses the light emitted by the backlight to display images. The LCDs used in mainstream mobile electronic devices use a group of light-emitting diodes on the back of the device as a white light source. Liquid crystals control the passage of light, and color filters add color to it. White light sources are expensive, so the display screens generally use blue light-emitting diodes, which are covered with phosphors to convert the emitted light into white light. Due to the limitation of fluorescent materials, the rendering ability of red light is weak, and the color mixing effect of the matching color filter is poor, and the final color gamut saturation is not good, which leads to the insufficient color gamut rendering abil...
