Session 48: Item 48.2 - Petree Hall Presentation Time: Thursday, May 22 at 11:00am to 11:20am Presenter: Takashi Nakamura, Toshiba Matsushita Display Technology Co., Ltd., Fukaya-shi, Japan Co-Authors: Hirotaka Hayashi, Masayoshi Fuchi, Masahiro Tada, Takayuki Imai, Hiroki Nakamura, Koji Shigehiro, Shinichi Hirota, Satoshi Maruyama, Akihiko Saitoh, Hiroyuki Kimura, Toshiba Matsushita Display Technology Co., Ltd., Fukaya-shi, Japan Synopsis: A new LCD having multiple ambient light sensors has been developed. Counters and a parallel-to-serial converter is integrated into the panel. Special clock drivers and data registers are included in a source driver LSI. The ambient light sensors perform well even for the case when one of the sensors is covered by a finger shadow.
Presentation: "Side-Lit Light-Guideless Flat LED Lighting Panel for Ultra-Uniform LCD Backlighting"

It is very important to examine and recognize the optimal and allowable limits of color difference in order to set targets for development of high quality displays. The ISO (International Organization for Standardization) has published the standards of ergonomics requirements for FPDs (ISO-FDIS9241-300~307 in 20072). We studied ergonomics requirements of maximum color difference to electronic displays through subjective evaluation experiments using several pictures of objects or landscapes with high and low color chroma to six color hues (Red, Green, Blue, Cyan Yellow and Magenta) and white and skin colors displayed on a wide color gamut display.
