JDI Develops a World-Class and Ultra-High-Definition LCD
651ppi Meets Typographic and Photographic Quality
June 4, 2012
TOKYO, June 4, 2012, Japan Display Inc. (JDI) (President: Shuichi Otsuka), a leading provider of LCD technology,
today announced that it has developed a world-class liquid crystal display (LCD) in the direct-view panel field that features a
resolution of 651ppi (RGB pixel pitch:39μm). Although the screen size is only 2.3-inches, the resolution format
of the display is 1,280 × 800 pixels (WXGA), which is comparable to those used in typical notebook PCs. From another perspective,
the resolution format of the newly-developed display is nearly twice the resolution of today’s high-resolution smart phone displays.
Today’s advanced communication capabilities have made operating systems more functional, enabling the construction
of large-capacity, high-speed wireless communication infrastructures. Accordingly, display screens used in information processing,
such as used in smartphones and tablets, need to display a large amount of information on a single screen and provide realistic,
In response to this growing requirement, the resolution of this newly developed display is about twice as high as that of
smartphone displays of the highest resolution that are being currently manufactured by JDI. The new JDI ultra-high definition
LCD with 651ppi resolution enables realistic and high-quality images that are comparable to film-based photographs.
Furthermore, when compared to low-resolution displays that hindered by jagged lines and characters,
this ultra-high resolution display enables exceptionally clear lines, letters and characters approaching typographic quality levels.
JDI has conducted an ergonomic study to evaluate the benefits this high resolution screen may have for the
human visual perception system. Based on our study of the sensory evaluation of letters appearing on this screen
very good results were achieved, which confirm that an ultra-high-definition display with 651ppi has utility as a
JDI will present this product and part of the evaluation results during the Session 64.1 at the Society for
Information Display’s (SID) Display Week 2012, an international conference and exhibition, to be held June 3 – 8, 2012,
at the Boston Convention and Exhibition Center (BCEC) in Boston, Massachusetts, USA.
