Products Description
Double-sided microstructured diffuser film Product Introduction
Double-sided microstructured diffuser film is a high-performance functional film used in optical displays. Both sides are covered with micron-scale precision optical structures. These microstructures efficiently scatter and homogenize light, effectively improving light distribution and eliminating issues such as light spots and dark areas. It is widely used in liquid crystal displays (LCDs), organic light-emitting diode displays (OLEDs), backlight modules, and lighting fixtures. Through its unique microstructure design, this film plays a key role in enhancing display quality and optimizing lighting effects, providing users with a clearer and more comfortable visual experience.
Excellent Optical Performance:
The double-sided microstructure design significantly improves light diffusion efficiency, increasing light uniformity to over 95%, significantly reducing glare, and providing users with a softer, more comfortable visual experience. Display devices deliver more detailed, lifelike images.
Balanced High Transmittance and Low Haze:
Utilizing advanced materials and processes, the display effectively diffuses light while maintaining a transmittance of over 92%, ensuring no loss of image brightness. This achieves a perfect balance of high transmittance and low haze, enhancing display clarity and vividness.
Dual-Sided Functionality:
Different microstructures on each side meet diverse optical needs. One side efficiently diffuses light, while the other optimizes light angles. This design is suitable for complex optical systems, increasing product design flexibility and expanding application scenarios.
Stable and Reliable Performance:
With excellent temperature and weather resistance, the display operates stably in environments ranging from -20°C to 80°C. It resists yellowing and aging over time, ensuring product lifespan and performance stability.
Double-Sided Microstructured Diffuser Film Production Process
Raw Material Preparation:
High-purity optical-grade polycarbonate (PC) and polyethylene terephthalate (PET) are selected to ensure their optical performance and stability. Raw materials undergo rigorous quality testing, including tests for transmittance, haze, and molecular weight distribution.
Mold Design and Manufacturing:
Based on the product's optical design requirements, high-precision microstructure molds are designed using computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies. The molds are manufactured using precision machining processes such as photolithography, etching, and electroforming, ensuring microstructure dimensional accuracy down to the micron level.
Extrusion:
Pre-treated raw materials are fed into the extruder, melted and plasticized under high temperature and pressure, and extruded through the die to form the pre-defined microstructure pattern on the film surface. Process parameters such as extrusion temperature, pressure, and speed are precisely controlled to ensure uniform film thickness and microstructure integrity.
Double-Sided Microstructuring:
The extruded film undergoes double-sided microstructuring. Different microstructures can be created on the other side of the film using processes such as embossing and coating. By adjusting process parameters, we achieve differentiated double-sided microstructure designs to meet diverse optical performance requirements.
Post-Processing and Inspection:
The formed film undergoes annealing to eliminate internal stress and improve its physical properties and dimensional stability. Optical inspection equipment is used to comprehensively test optical performance indicators such as transmittance, haze, and uniformity. Physical indicators such as thickness and surface quality are strictly controlled to ensure product quality standards are met.
Slitting and Packaging:
Qualified films are slit according to customer specifications to produce products of varying specifications. Dust-free packaging is used to prevent contamination and damage during transportation and storage.
| C-Series Microstructured Diffuser Film | Body Diffuser (with Scattering Particles) |
