東芝(Toshiba)的顯示器公司TMD(Toshiba Mobile Display)今天(2011/10/20)發布他們將在橫濱光電展展出超高解析度LCD面板.
這面板是6.1寸大小, 解析度是比Full HD(1,920×1,080)還要來的高的2,560×1,600高解析度, 更令人驚訝的是居然是製作在6.1″大小的面板, 也就是說在一平方英吋裡要塞進498個完整像素(498dpi), 這是多麼精密的技術. 官方提供一張解析度成像的比對照片, 可以看的出來498DPI的文字呈現幾乎與筆寫出來的沒兩樣.
這技術就是使用我們之前介紹過的LTPS(low-temperature poly-silicon)低溫多晶矽 技術所製造的TFTLCD, 但可惜的是NTSC只有達61%, 想必是因為高DPI造成穿透率不佳, 所以若加上高飽和度的色阻後會讓發光效率更低.
我想這麼高解析度的面板已經遠遠超越人眼可辨識的水準(未來的視網膜體驗), 看來實用性不高, 但是以技術宣示性是相當不錯的. 下面是TMD提供的新聞稿給大家參考一下
Toshiba Develops World-Class, High-Definition LCD Panel
Toshiba Mobile Display Co., Ltd. (President: Masahiko Fukakushi) today announced that it has developed a liquid crystal display (LCD) panel that features a world-class, high-definition 498 pixels-per-inch (ppi) image in a direct-view, compact 6.1-inch screen. Despite the small screen size, the display resolution format is 2,560 × 1,600 pixels, a higher resolution than even the full HD resolution format of 1,920 by 1,080 pixels.
In recent years, sophisticated operating systems (OS) have been developed which utilize advanced telecommunication facilities and provide a large-volume, high-throughput communications infrastructure. Based on the capabilities of this enhanced infrastructure there are increasing demands for the display screens of information processing terminals, such as smartphones and tablet-type devices, to display large amounts of information on a single screen for quick processing and operation, and for more realistic screen images, potentially even in 3D.
This newly-developed world-class, high-definition LCD panel is based on our processing techniques for forming fine-pitch and high-performance, low-temperature poly-silicon (LTPS) thin-film transistors (TFT) on glass substrates, and other precise fabrication techniques which have been cultivated over the years. This direct-view LCD panel achieves high-definition images with photographic quality, and although the images are displayed in 2D format, they impart a sense of depth and realism.
