On April 19, 2024, Shanghai Jade Bird Display Technology Co., Ltd. (Jade Bird Display or "JBD" for short) officially launched its AR optical waveguide image quality correction device: ARTCs. As the industry's first feasible technical solution targeting the challenge of diffraction optical waveguide display uniformity, ARTCs has made significant breakthroughs in display quality. This will propel AR optical waveguides into a new stage of ultimate visual experience and consumer-level applications.
The MicroLED + diffraction optical waveguide solution offers advantages such as small size, high brightness, low power consumption, and thinness with high transparency. It perfectly aligns with the current trend towards lightweight iterations of consumer-grade AR glasses, becoming the mainstream choice in the industry. However, due to manufacturing process limitations, diffraction optical waveguides suffer from display defects like uneven brightness and color distortion. There are also significant individual differences between each set of waveguide slices. These issues not only fail to meet consumers' demands for high-quality AR image display but also hinder the wider adoption of optical waveguide products.

ARTCs Process Flowchart
JBD's ARTCs provides a systematic solution for the image quality issues of diffraction optical waveguides. The solution consists of three parts: the ARTCs optical waveguide image quality correction device, proprietary calibration algorithms, and on-board light engine computing. It aims to eliminate the display irregularities and individual differences present in optical waveguides during actual usage, significantly enhancing the visual experience of optical waveguides.

ARTCs Calibration Comparison

After testing and data verification, the global brightness uniformity of the diffraction optical waveguide optimized by ARTCs has improved from "80%". The color difference ΔE has decreased from ">0.1" to "0.02", significantly reducing color distortion and visual artifacts such as graininess. The screen uniformity has been significantly improved. Additionally, ARTCs supports real-time image correction at the hardware IC level (Demura), enabling system-level uniformity compensation calculation and image quality optimization for MicroLED microdisplays combined with optical waveguides in a single calibration.

ARTCs Optical Waveguide Image Quality Correction Device
One of the key components of ARTCs is the automated optical waveguide image quality correction device developed by JBD. It features pixel-level color and brightness data measurement, extraction of optical properties of the waveguide, and calculation of correction parameters. Combined with proprietary algorithms for human visual perception, image computation, and display processing, it can quickly optimize and correct the image quality of optical waveguide AR glasses. This provides a one-stop calibration solution for AR terminal brands. Currently, ARTCs-WG has been introduced into production lines and is about to enter mass production and delivery.
This groundbreaking achievement signifies that ARTCs has overcome the previous process limitations of diffraction optical waveguides, significantly reducing the display unevenness in diffraction optical waveguide images, greatly enhancing the visual experience of consumer-grade AR. At the same time, ARTCs has filled a market gap, pushing the image quality of optical waveguide displays to a new milestone.
As a crucial step taken by JBD in the field of near-eye displays, ARTCs also brings new opportunities for the collaborative development of the AR industry chain. In the future, driven by innovative research and development, JBD will strive to provide the industry with higher-quality near-eye display solutions, pushing forward the continuous progress of AR glasses towards excellent image quality, lightweight design, and all-weather functionality.
