JBD Introduces AR Waveguide Display Test and Correction in China

Jade Bird Display Ltd. (JBD) has introduced a groundbreaking technology known as the Adaptive Refractive Tunable Correction (ARTC) system to enhance the performance of diffractive waveguided augmented reality (AR) glasses. While the company does not provide detailed information on the inner workings of the equipment, it emphasizes that the ARTC system conducts waveguide image quality measurement followed by "projector-side computing."

According to JBD, the ARTC system is designed to extract waveguide characterization data and calculate correction coefficients to address non-uniformities in waveguide-displays. This comprehensive solution can correct irregularities originating from the waveguide, microdisplay, and projector simultaneously, streamlining the optimization process.

The introduction of ARTC marks a significant advancement in the realm of waveguided AR glasses, as it effectively mitigates issues related to brightness and color non-uniformity that were prevalent in previous iterations. JBD touts the ARTC system as a "major breakthrough" in the industry, offering a solution to common problems such as color distortion and image graininess.

By leveraging the capabilities of ARTC, JBD asserts that global brightness uniformity can be increased from under 40 percent to over 80 percent, while the color difference ΔE can be reduced from more than 0.1 to 0.02. These improvements result in a more visually appealing and immersive AR experience for users, setting a new standard for waveguided AR smartglasses.

One of the key components contributing to the enhanced performance of JBD's AR glasses is the red microLED technology, which boasts a brightness exceeding 1 million nits. This high level of brightness not only enhances the overall visual quality of the display but also contributes to a more vibrant and dynamic viewing experience for users.
