Luminescent Cavity Design for High Ambient Contrast Ratio, High Efficiency Displays [PDF]
, 2022 Abstract A key display characteristic is its efficiency (emitted light power divided by input power). While display efficiencies are being improved through emissive (e.g., quantum dot and organic light emitting display (OLED) designs1,2, which remove the highly inefficient color filters found in traditional liquid crystal displays (LCDs)3,4 ...
