Display Metrology and Image Quality Are Relevant, Vital for Development

摘要

THE adage "If you can't measure it, you can't improve it" certainly applies to the optical performance of front-of-screen displays. Valid and robust display characterization is crucial to the timely development of display technology and of devices that use that technology. In fact, it's a critical component of the "fail fast" methodology of product and technology development. Engineers need trusted data to succeed. Data that confirms a null result is just as valuable as data that supports an idea, if not more so. Display metrology continues to be an important component of SID's Display Week, as evidenced by the strong metrology showing in 2018 at the symposium, in seminars, in standards meetings, and on the exhibit floor. But there's a lot more to display metrology than pointing a luminance meter at the screen and pushing a button. Good data comes from understanding the idiosyncrasies of different display technologies, proper measurement techniques, and a competent analysis and understanding of the measurement result and how it relates to the purpose of the display in the system.
