Brightness and vividness lead to better viewing for UHD, HDR programming

Abstract

Modern display appliances have increased picture quality by taking advantage of high-pixel resolution and High Dynamic Range (HDR) in new-age OLED-based products. This trend will become pervasive with the continued proliferation of underlying technologies. This paper helps point researchers to modeling those accounts for the increase in picture quality. The TV market has a growing number of HDR products, as listed by the popular consumer review website, RTINGS.com. They include many ultra-high definition (UHD), HDR televisions that exceed 1000 candela-per-meter-squared (cd/m²) peak luminance as reported by Babcock (2023). Also, the monitor and notebook HDR market is growing evident by the number of HDR display products certified by the VESA (Video Electronics Standards Association) DisplayHDR logo compliance program. Relying only on wattage to increase luminous intensity, however, is neither subtle nor cost effective. Sheer brightness in a typical ‘UHD/HDR’ television may be desirable but isn’t the only tool available to display makers. This talk reviews models that assess ‘UHD/HDR' displays for their clarity, brightness and most importantly their vividness. Quantum dot pixel-rendering technology has driven image vividness to new levels when matched with an OLED-emissive pixel (QD-OLED) according to supporting researched cited herein. Quantum dot advances that are in fact necessary for advancing the state-of-the-art in UHD imaging for televisions and computer monitors. This presentation will emphasize the importance of an augmented color appearance model for HDR technology that can reach beyond the DCI-P3 color space.
