The Hitachi DX07 is a 2.9 inch (73 mm) liquid crystal display screen which went into mass production in December 2006: *62mm x 37mm *800x480 pixels *1.677 million colours *400:1 contrast ratio *250cd/m2 *IPS TFT (in-plane switching) Each pixel is therefore 78µm x 77µm (1µm = 1/1000mm). Note: It's also safe to assume that this is an 8-bit per channel display (a 6-bit per channel display can only dither 1.62 million colours) ==Optical Properties of the DX07== The DX07 has a number of interesting properties related to its small size and high resolution. The following are true for someone with "normal" vision using this screen as a hand held device: *Smallest pixel size to comfortably view a hand held device without loss of detail *Smallest hand held screen without loss of detail for NTSC DVB content (720x480 pixels) *Smallest hand held screen without loss of detail for NTSC DVD content (720x480 pixels) Notes: *"Normal" vision is when someone can distinguish detail at 1/60 of a degree (an arcminute) *The closest a hand held screen can comfortably be viewed is 250mm (approx. 10 inches) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hitachi DX07」の詳細全文を読む スポンサード リンク
