20‐3: The Study of Ambient Contrast Ratio of Transparent MicroLED Displays for Applied Field Extension

SID Symposium Digest of Technical Papers, 2023
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.

Improving Ambient Contrast Ratio of Display Device at Oblique Angle Using a Fe3O4-Magnetic Particle Chained Pillar Array Structure

Journal of Electronic Packaging, 2023
Abstract A high ambient contrast ratio (ACR) is essential for achieving a high dynamic range in advanced display applications, but reported ACR enhancement strategies always result in reduced optical efficiency of light-emitting diode (LED) display devices.

P‐49: Improvement of Contrast Ratio in Bright‐Ambient Color ACPDP with High Resolution

SID Symposium Digest of Technical Papers, 1998
Abstract Contrast ratio in bright ambient is one of the most important factor of image quality in display picture. In this paper, it is reported that the contrast ratio is improved by applying a reflective structure with white ribs. The structure is applied to surface discharge ac‐PDP with high resolution of 0.13mm, the contrast ratio

Improving Ambient Contrast Ratio and Color Uniformity of Mini Full Color Light-Emitting Diodes Using an SiO2/Graphite Bilayered Packaging Structure

Journal of Electronic Packaging, 2021
Abstract Mini full-color light-emitting diodes (mini-fc-LEDs) are a promising solution for display applications, including outdoor, cinema, and wearable devices, owing to their high resolution. However, it is difficult to simultaneously obtain high color uniformity and ambient contrast ratio (ACR).

Contrast ratio for transmissive‐type TFT‐addressed LCDs under ambient‐light illumination

Journal of the Society for Information Display, 1993
Abstract— 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, 2007
We 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

74‐1: Invited Paper: Can LCDs Outperform OLED Displays in Ambient Contrast Ratio?

SID Symposium Digest of Technical Papers, 2018
We analyse the ambient contrast ratio (ACR) of LCDs and OLED displays at different viewing angles for smartphones, TVs, and public displays. Four primary factors affecting the ACR are surface reflection, light leakage of polarizer, device contrast ratio, and display brightness. Methods for enhancing the ACR of LCDs and OLEDs are discussed.

P.139L: Late‐News Poster : The Advantage on Ambient Contrast Ratio in WRGB OLED Display

SID Symposium Digest of Technical Papers, 2013
Abstract We released WRGB OLED Display for TV. The most remarkable difference between ‘WRGB’ OLED Display and ‘RGB’ OLED Display is the usage of Color Filter. So that WRGB OLED Display using Color Filter absorbs light from coming outside and has low reflection characteristics.

P‐19.7: Ambient Contrast Ratio Improvement of Low Reflection LCD for Automotive Application

SID Symposium Digest of Technical Papers
A LCD for a 12.3 inch vehicle dashboard was proposed to enhance ambient contrast ratio. The LCD can achieve 0.8% reflection by using AR treatment and optimizing shielding layer material. It demonstrates high contrast ratio and color gamut under high ambient light situation.

P‐88: Low reflection antistatic material design for improving ambient contrast ratio of LCD Panel

SID Symposium Digest of Technical Papers
To enhance the ambient contrast ratio of LCD panel, the reduction of panel reflectance must be considered. A new antistatic material composition is designed to lower the refractive index, and the multilayer structure is derived based on optical simulation.
