21‐3: Quantum Rod Color Filters with High Ambient Contrast Ratio

Digest of Technical Papers SID International Symposium, 2023
Applying 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 ...

High ambient contrast ratio OLED and QLED without a circular polarizer

Journal of Physics D: Applied Physics, 2016
A high ambient contrast ratio display device using a transparent organic light emitting diode (OLED) or transparent quantum-dot light-emitting diode (QLED) with embedded multilayered structure and absorber is proposed and its performance is simulated. With the help of multilayered structure, the device structure allows almost all ambient light to get ...

Effect of character contrast ratio of tablet PC and ambient device luminance ratio on readability in low ambient illuminance

Displays, 2018
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 ...

P‐101: High Ambient Contrast Ratio OLED and Quantum‐dot LED without a Circular Polarizer

SID Symposium Digest of Technical Papers, 2016
A high ambient contrast ratio display device using a transparent OLED or transparent Quantum‐dot LED (QLED) with embedded multilayered structure and absorber is proposed. With the help of the multilayered structure, the device structure allows almost all ambient light to get through the display and be absorbed by the absorber.
