用網點模擬灰階不見得是那麼糟，可是前題是解析度要夠高才行。]]>Feb 8th 2009 10:13AMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/很好奇灰階數有多少，怎麼還要靠dithering來做呢？]]>Feb 6th 2009 7:58PMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/ 換頁非常緩慢（要個十幾秒才能換一頁）

換算LCD的更新頻率，不就是 10000ms - 20000ms 了...
完全不能用來放短片！

想說，可以像哈利波特裏面那種魔法報紙...

當然，機器本身的 IC 及電路可能還是會吃些待命所需的電啦....]]>Feb 6th 2009 10:44PMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/Feb 6th 2009 10:20PMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/Feb 7th 2009 2:03AMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/Feb 8th 2009 3:55AMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/Bridgestone 的電子紙基本上是用杯狀構造封裝帶電的流體粉末（Liquid Powder），跟 E-Ink 或 SiPix 的 EPD 不一樣的是他們的「杯子」裡面是空氣，耗電量比前述二者高很多（ E-Ink 用 15V，SiPix 從 15~40V 之間看速度和白度需求調整，Bridgestone 的要 70~80V）所以，要同樣省電的時候，換頁會換得比較久。

灰階是藉由微妙的電壓控制讓裡面的流體粉末在不同距離停住而形成的。

彩色應該也是用 color filter 吧，沒記錯的話....所以，沒有背光模組，看來都會很黯淡。]]>Feb 7th 2009 9:42AMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/e vai ser melhor ainda se as telas fossem dobráveis]]>Feb 7th 2009 12:20PMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/Feb 8th 2009 10:36PMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/Feb 9th 2009 5:40AMhttp://chinese.engadget.com/2009/02/06/a3-sized-epaper/http://chinese.engadget.com/2009/02/06/a3-sized-epaper/隨便舉例，本來應該用 80V 的電壓，他們刻意只用 50V 去驅動，
原來可能只要跑 0.001 秒就可以到位的粒子變成要跑 0.009 秒才跑得到，
那就會變得很慢了。
（數據是我隨口說，請勿當真啊...）]]>Feb 9th 2009 11:24AM
