As a wholly-owned subsidiary of Daoming Optics, Changzhou Huawei New Materials Co., Ltd. has built over 20 years of expertise in the optical film industry. Focusing on the R&D and manufacturing of high-end optical and functional films, the company boasts an annual production capacity of 36 million square meters. Its optical film products stand as mature, mass-produced solutions that effectively replace imported alternatives.
1. Core Product Portfolio
Optical Display Film Series
Brightness Enhancement Films:
Utilizing 1H3L and random prism structures, these films are ideal for MNT/TV, NB, and other display devices. Variants are available with different base thicknesses, prism designs, brightness gains, and back-coating treatments to meet specific customer and application needs.
Composite Films:
These combine two or more optical functional layers into one, significantly enhancing performance beyond that of single-function films.
DOP Composite Brightness Enhancement Film:
Features a high-haze top layer for wide viewing angles and privacy, and a large-pitch prism bottom layer for increased brightness. Through various designs of haze, prism structure, and thickness, the film supports both large-size TVs and mid-size MNT displays.
MOP Composite Brightness Enhancement Film:
Engineered with micro-lens and prism hybrid structures, it delivers both wide viewing angles and high brightness. Micro-lens sizes range from 25μm to 34μm and are arranged randomly or in honeycomb patterns to reduce interference patterns—ideal for high-end TVs and monitors.
COP/CPP Prism Reflective Polarizing Films:
Representing the trend toward “optical film integration” in backlight modules, these films replace traditional BEF + DBEF combinations, saving space while utilizing polarization recycling and prism focusing. They are core brightness components in ultra-thin TVs and automotive displays.
DBEF-Like Polarized Reflective Brightness Films:
Multiple mass-produced models (e.g., HRF-H250T2, HRF-350C1, HRF-390C1) are available. These use nanometer-level multilayer or Brewster-angle film structures to recycle light polarization and enhance energy efficiency—key components in LCD energy saving and high brightness applications.
DPP Composite Brightness Enhancement Film:
A three-layer film composed of a diffusion layer, top prism film, and bottom prism film—replacing traditional “diffusion + top BEF + bottom BEF” assemblies. The diffusion layer contains PMMA microbeads for 85%-95% haze and Moiré suppression. Single-layer brightness gain exceeds 60%, and dual-layer cross structures can reach 120%—ideal for high-end TVs and displays.
POP Composite Brightness Enhancement Film:
With a dual-prism laminated structure, this film outperforms MOP and DOP in optical efficiency. Rounded or flat-top prisms reduce brittleness and scratch risk. A jittered pattern disrupts periodicity to minimize Moiré effects. It supports ultra-thin customization, widely used in LCD TVs, tablets, and laptops, as a core component to improve energy efficiency and reduce power consumption.
Functional Films for New Energy
Photovoltaic Gap Films:
Designed to enhance the performance and durability of PV modules, these films offer 85% reflectivity, improving light-to-electricity conversion. Their excellent UV and weather resistance ensures long-term outdoor reliability. After 1000 hours in a 85°C/85% RH environment, tests show no delamination, bubbling, or discoloration.
2. Breakthroughs in New Product Development
Privacy Protection Films:
Engineered with specialized optics to block side viewing angles, these films come in HD and matte TPU/PET materials. The HD version offers high transparency, while the matte version is anti-glare. Both provide 30° privacy protection, nano-level self-healing against scratches, high toughness, and anti-shatter performance—enhancing overall device safety.
Looking Ahead
Huawei Optical Films remains focused on market demand and continuously enhances product performance and user experience. With an eye on emerging technologies and innovations, the company is committed to providing safer, more convenient, and more efficient privacy protection solutions, reinforcing its leadership in the optical film industry.
