From LED to AR Glasses: How High-Refractive Materials are Shaping the Future of Technology?

What are the main applications of high-refractive titanium dioxide TiO2?

In everyday life, many applications involve the use of high-refractive materials. For example, in-car screens utilize a combination of low and high-refractive materials to enhance transparency, reducing screen glare and making the display clearer. This is not limited to the automotive industry. In next-generation displays such as MicroLEDs, there is a significant refractive index mismatch between the emitting layer and the glass. High-refractive materials can be used as a refractive index buffer layer, greatly reducing light refraction and thereby increasing brightness. In new-generation optical products like AR glasses, smartphones, and 3D facial recognition, high-refractive materials offer high flexibility, enabling an expanded field of view, sensor miniaturization, and improved recognition accuracy.

Currently, high-refractive materials on the global market often use zirconium oxide as the raw material, with refractive indexes around 1.6-1.7, which comes with certain limitations. To meet the need for refractive indexes of 1.7 and above, a unique coating and dispersion process has been developed to create nano-grade titanium dioxide specifically for optical products. This material does not affect light transmittance and can be applied to various oil-based and UV systems, significantly enhancing the overall refractive index of formulations. The refractive index can also be adjusted by varying the amount added to meet different high-refractive applications. Currently, it is widely used in LED, 3D sensing, displays, AR grids, chip packaging, anti-reflection coatings, and more.

Benefits of Using High-Refractive Materials:
Smartphones, optical lenses, and sensors can achieve higher brightness (thinner films).
Transmission losses during light propagation through films, such as in VR glasses, can be reduced.
The refractive index mismatch between LED emitting layers and display glass can be minimized, allowing more effective light emission from LEDs.
When combined with low-refractive materials, surface reflection can be significantly suppressed, preventing glare and unwanted reflections of surrounding backgrounds.

In summary, the key functions are:
a. Enhanced visual identification
b. Increased brightness
c. Improved recognition accuracy
d. Expanded field of view
