(iTers News) – The race is on for control of the fast-growing global mobile display markets. At the heart of the battle is who will be able to pack more of pixels into a tiny screen size to achieve as high resolution as possible.
Japan Display, a newly incorporated-mobile display manufacturing entity, showed off an ultra high-definition-capable 2.3-inch LCD for use in smartphones at SID Display Week 2012.
Cramming 651 pixels into one inch line, or 651ppi, the allied force of Sony, Toshiba and Hitachi mobile display business unit has achieved a UHD resolution of 1,280 x 800 pixels on a tiny 2.3-inch screen size in what it said is twice that of today’s highest resolution smartphone available on the market.
It also almost matches the screen quality that people can watch on a typical notebook PC.
To pack more than 1 million pixels on such tiny screen space, Japan Display reduced each RGB pixel pitch to 39 micrometers –one micrometer is one millionth of one meter-
The technology wonder came just a couple of days after LG Display of Korea unveiled a full HD-capable 5-inch mobile LCD, boasting 440ppi, or 1920x1080 resolution.
Japan Display is a third-party joint venture TFT-LCD manufacturing, which was collectively funded Sony Mobile Display. Hitachi and Toshiba to fight back the dominance of global mobile display market by neighboring arch-rival Samsung Mobile display and LG Display.
[sws_toggle1 title="PR News"> Tokyo - 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*1 (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, high-quality images. 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 man-machine interface*2. 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.
