Unique embedded microstructure original technology, the conductive structure is embedded in the substrate without being exposed, and the square resistance is less than 5 ohms/square, which avoids the electron migration effect and has long-term stable performance. Through the line width below 5 microns and nano-level filling materials. The moiré pattern is eliminated, and the absolute transparency is higher than 87%. The use of mold preparation, the internal and external circuits are formed at one time, which reduces the subsequent processes and the defect rate, and meets the mass requirements of consumer electronics, and the process has no emissions.


Electromagnetic shielding film

Diffusion film

· Mainly used in the lighting industry


The light passes through the microlens array prepared on the film to realize the directional diffusion of the LED point light source, so that the light undergoes a lot of refraction, reflection and scattering, and the light is corrected into a uniform surface light source to achieve the effect of optical diffusion. It has the advantages of high light extraction efficiency, low energy consumption, and no pollution.
