Volumetric scattering layer for flexible transflective display

Abstract

A flexible transflective liquid crystal display (FTF-LCD) which combined a flexible LCD and a flexible organic light emitting diode was demonstrated. Under high light ambience (reflected luminance of 250 nits), a LCD incorporated with a volumetric scattering layer (VSL) showed a contrast ratio of 10 : 1 at the viewing cone of 60 degrees in the reflection mode. By adding the VSL to the LCD, the haze component was increased by a factor of 3.3. With the advantages of small form factor, flexibility, power-saving, and legibility in bright ambience, the FTF-LCD is very applicable to mobile products.
