18‐4: Late‐News Paper: Lambda Capture method ”λ‐Capture” and the applications for quality control of Displays and the devices

This paper describes a new, fast, Wave‐Length of Center‐of‐gravity (WLC) detection method, named “λ‐Capture”. The paper presents and explains the principle of this new technology as a wavelength management technique for displays, utilizing a Linear Reflectance Gradient on the wavelength axis (LRG) dichroic mirror. It is then applied to a mini‐LED wafer: sample of actual display elements and demonstrated to have satisfactory performance. Furthermore, the possibility of new applications based on this principle is demonstrated.
