A study on a driving method of OLED displays for better motion image quality with adaptive temporal aperture control

Takenobu Usui, Yoshimichi Takano, Toshihiro Yamamoto

Journal of the Society for Information Display > 25 > 8 > 472 - 479

Degradation of motion image quality by motion blur on hold‐type displays, such as liquid‐crystal displays and organic light‐emitting diode displays, is a well‐known issue. To improve motion image quality, a driving method with a shorter temporal aperture has been proposed. However, a shorter temporal aperture requires higher instantaneous luminance on displays. Higher instantaneous luminance accelerates...

P‐1: Fabrication of a Short‐Channel Oxide TFT Utilizing the Resistance‐Reduction Phenomenon in In‐Ga‐Sn‐O

Mitsuru Nakata, Mototaka Ochi, Hiroshi Tsuji, Tatsuya Takei, more

SID Symposium Digest of Technical Papers > 48 > 1 > 1227 - 1230

The resistance of an In‐Ga‐Sn‐O (IGTO) film with a SiN_x /SiO_x passivation layer was found to decrease significantly by thermal annealing, due to hydrogen diffusion from the SiN_x layer into the IGTO film through the SiO_x layer. We propose a method that utilizes this “resistance‐reduction phenomenon” to reduce the effective channel length in IGTO thin‐film transistors with a SiN_x /SiO_x passivation layer...
