21‐3: Quantum Rod Color Filters with High Ambient Contrast Ratio
SID Symposium Digest of Technical Papers, 2023Applying quantum dot (QDs)‐based photoluminescent color filter arrays to mono‐color OLED displays and liquid crystal displays is considered a promising method to broaden the color gamut and boost the brightness and efficiency of the display. However, the ambient light could excite the semiconductor QDs and QRs, decreasing the display ambient ...

Research of testing display ambient contrast ratio
2011 IEEE 3rd International Conference on Communication Software and Networks, 2011To investigate the flat-panel display characteristic, and improve display industry development. As the international standards developed or adopted, ambient contrast ratio of display is a significance indicator. In this paper, we measured the ambient contrast ratio of display by several methods, included integrating sphere method, spectrum analysis ...

Abstract This study examined the relationship between the ambient and surface luminances needed to obtain optimal and minimum allowable device (paper and tablet) readability in low ambient illumination environments (illuminance of less than 300 lx). In addition, the optimum and minimum allowable surface luminances were evaluated according to ambient ...

This paper aims to investigate the ambient contrast ratio of transparent displays in AR/MR applications. Transparent OLED displays in indoor environments have been widely applied. However, the high ambient brightness in outdoor environments limits the application field due to poor ambient contrast of OLED.

Contrast ratio for transmissive‐type TFT‐addressed LCDs under ambient‐light illumination
Journal of the Society for Information Display, 1993Abstract— The relationships between the contrast ratio, display luminance, and display diffuse reflectance are examined for the transmissive‐type twisted‐nematic TFT‐LCD under ambient‐light illumination. Expressions to estimate the contrast ratio under ambient light were derived.

Emi-Flective Display Device with Attribute of High Glare-Free-Ambient-Contrast-Ratio
Japanese Journal of Applied Physics, 2007We have demonstrated the integration of an organic light emitting device (OLED) and a reflective liquid crystal display (R-LCD) which was termed an emi-flective display. The glare-free-ambient-contrast-ratio (GFA-CR) was used to evaluate the image quality of display devices under ambient light. Through integrating the OLED with R-LCD, the GFA-CR of the
