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. The company's approach to improving waveguide image quality involves a unique process that combines waveguide characterization, correction coefficient calculation, and projector-side computing.
According to JBD, the ARTC system represents a significant advancement in the field of AR glasses, addressing issues related to brightness and color non-uniformity that were prevalent in waveguide displays prior to the introduction of this technology. By applying correction algorithms at the system level, the ARTC can effectively mitigate non-uniformities originating from the waveguide, microdisplay, and projector in a single operation.
One of the key benefits of implementing the ARTC technology is the substantial improvement in brightness uniformity and color accuracy achieved in waveguided AR smartglasses. JBD claims that the use of ARTC can elevate global brightness uniformity from below 40 percent to over 80 percent, while reducing the color difference (ΔE) from more than 0.1 to 0.02. This enhancement results in the elimination of visual artifacts such as color distortion and image graininess.
With the introduction of the ARTC system, JBD aims to set a new standard for waveguided AR glasses, offering users a more immersive and visually appealing experience. By leveraging advanced image processing techniques and precise calibration methods, the company is able to deliver AR glasses that exhibit superior image quality and color accuracy, enhancing the overall user experience.
In addition to the ARTC technology, JBD has also made significant strides in microLED display technology, achieving red microLED brightness levels exceeding 1 million nits. This breakthrough in microLED projector technology further complements the capabilities of the ARTC system, enabling JBD to offer small yet powerful microLED projectors that can enhance the performance of AR glasses.
