20.4: Distinguished Paper: Optimizing the Brightness of Reflective Displays in Mobile Applications

Ion Bita; Hamid Tavakoli; Evgeni Yuriy Poliakov; Kebin Li; Thomas Gerald Fiske; Jennifer Gille; Russel Allyn Martin

Reflective display brightness is studied in mobile devices as a function of relevant ambient conditions, supplemental frontlight illumination, and display reflectance properties. Results for varying scattering properties in specular modulator-based displays such as mirasol®, as well as combinations of ambient and internal frontlight illumination conditions for optimizing the user experience across various lighting environments are presented.

Optimized diffusers for reflective mirasol displays: experience from metrology characterization

Evgeni Yuriy Poliakov; Russel Allyn Martin; Ion Bita; Matthew B. Sampsell

Optical component differentiation (diffusers and light processing elements) between reflective displays based on Interferometric Modulation (IMOD) and typical transmissive (LCD) displays is discussed. We characterize optimized diffusers for a front light of reflective displays and present the key differentiation data with important metrology tools to monitor the image quality. Drawing on our experience, we outline guidance going forward.
