Large-sized OLED displays require advanced technologies to realize mass production. The competitiveness of OLED TV comes from the combination of oxide TFT and WRGB OLED technology. Those technologies including image quality of OLED TV, oxide TFT, WOLEDs, and solid phase encapsulation enable panel size scalability as well as mass production with lifetime reliability. We will introduce technological progress for commercializing large-sized OLED TV.
Ultra‐high definition (UHD) curved organic light‐emitting diode (OLED) TV requires advanced technologies to realize mass production. White, red, green, and blue (WRGB) OLED TV based on stripe WRGB sub‐pixel structure has distinct advantages in luminance of white, faster response time, wider viewing angle, and potential higher resolution. In this paper, we will introduce technological progress for commercializing large‐sized and UHD curved OLED TV. Those technologies including oxide thin film transistors, white OLEDs, compensation circuit, and solid phase encapsulation enable panel size scalability as well as mass production with lifetime reliability.
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.
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.
