Perception of sparkle in anti‐glare display screens

Abstract

In this paper, we describe a series of psychophysical experiments to quantify the relationships between anti‐glare (AG) glass treatments and perceived sparkle in emissive displays. The experiments show the following: (1) that a new measure, pixel power deviation, correlates well with perceived sparkle; (2) that for a given AG treatment, sparkle is worse on high‐pitch displays; (3) that tests of sparkle using small samples provide a conservative bound on perceived sparkle in display‐sized samples; and (3) that sparkle visibility is affected by the content of displayed images. The goal of these efforts is to enable the development of AG glass treatments for emissive displays that effectively reduce front surface reflections while preserving high image quality.

“…Accordingly many techniques have been developed to improve the reflection of the display screen by applying anti-reflective (AR) films [4][5] and polarizers [6]. While anti-glare (AG) films can reduce unwanted reflections, they can also result in sparkling dots and blur the displayed information when combined with the subpixel structure of the screen [7]. Gaming displays, with their different emitting technologies and physical structures, may exhibit different reflection properties that can impact overall visual experience.…”

“…In 2014 Ferwerda et. al quantified sparkle with a pixel power deviation approach mimicking a human eye for detection and showing that the results correlate well with perceived sparkle and that sparkle is also affected by the shown image [4]. In 2015 Evans et.…”

P‐37: Wide‐Viewing—Angle Anti‐Reflection and Anti‐Glare Surface Treatment on the Cover Glass for Auto‐Interior Applications

“…We have developed the AG surface on Corning® Gorilla® Glass by using a chemical etching method that enable ultra-low sparkle performance suitable for high resolution display up to 300 PPI as the other LS AG suitable for <200 PPI resolution. AG glass optical properties are analyzed: SCE/SCI, transmission haze, gloss, distinctness of image (DOI), and sparkle [1,2,3]. The balance of these five metrics is the key to maximizing the benefits of AG for display readability, tactility on the glass surface, and the aesthetic appearance of high-performance touch displays in the Auto-Interior design.…”
