OLEDs have excellent ambient contrast, because OLEDs with a circular polarizer can effectively reduce the reflectance caused by external light. However, for better blackness, it is necessary to improve reflectance and reflection color. By applying new material, blackness of OLED TV is improved.
We have studied the efficiency improvement of OLED TVs using high transmittance technology and reversed quarter wave plate (r‐QWP) of the improved polarizer. It helped that the efficiency of OLED went up, so that power consumption and life time of OLED panels have been improved. In this paper, study on the efficiency improvement of OLED TV using new high transmittance polarizer will be presented.
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. We expect WRGB OLED Display to be more daylight‐readable Display than ‘RGB’ OLED Display, even though RGB OLED is using ‘Reverse Dispersive QWP’
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
