Screen Protector Superhard-AR
OTAO has developed a new ultra-hard anti-reflectivecoating process, which improves the surface hardness and an-ti-light reflection of glass protectors, and enhances the userexperience of glass protectors.
The transmittance of normal glass protectors is 90%-92%,while the OTAO superhard AR glass is 95%-96%. With the combination of anti-reflection and high transmittance, after using OTAO superhard AR glass protectors,the colors displayed on mobile phones or tablets will be morevivid and realistic.
Super Smooth AF Coating
From a technological point of view, it is very difficult to make AF very smooth by coating a layer of AF on the surface of super-hard AR, but OTAO superhard AR over-comes this difficulty. The initial water drop angle tested can reach 115 degrees -120 degrees (the AF water drop angle of AR products in the industry is 110-115 degrees). When touching the surface of OTAO superhard AR glass protectors with finger-prints, it feels very smooth and not easy to leave fingerprints.
Full Process Precision Manufacture
Integrating intelligent sensing and data analytics technology to conduct real-time monitoring and precise control of all production links, ensuring product consistency and stability, and achieving high-efficiency and high-quality production.
Especially OTAO has experience in building ownedbrands and serving brand clients, OTAO hasassembled precise machines of production and fullsets of test machines for each procedure, at thesame time, expanding the QC team, optimizingeach procedure, and adding more procedures toqualify.
Product Full Inspection
We have established multi-dimensional quality inspection standards that integrate automated testing equipment with manual re-inspection to conduct comprehensive performance and appearance checks on every product, ensuring zero defects in all products leaving the factory.
In addition, we have implemented a comprehensive SOP and a Total Quality Management (TQM) system to control the quality of every raw material, process, and finished product. This ensures on-time delivery, rapid response, product qualification, reliable after-sales support, and the ability to stay ahead of market trends.
