什么是便宜的小型电子墨水显示器？[关闭]

11

我正在寻找一种电子墨水显示器（基于像素），它尽可能便宜，并且体积小巧，但仍是可以在一百毫秒内刷新的完全基于像素的显示器。

我所指的几乎是Aveso的“定制显示器”产品。但是它们是不可变的显示，即不是基于像素的。

显示器必须非常小-1厘米，理想情况下，它们可以与多头控制器配合使用。

很奇怪-当我刚尝试访问avesodisplays.com时，Chrome发出了恶意软件警报。

@aSandwich，似乎您可以带病毒去。

@roberto，由于恶意软件，我删除了链接。

在短时间内，我考虑过修改显示屏的想法。然后跟进e-Ink Corporation。他们是持有eInk IP的人。他们把我介绍给了一家知名的LCD制造公司PrimeView。（当我用谷歌搜索一些事实时，事实证明PVI现在已经收购了EInk。）

我可以将自己的方式介绍到一些数据表和定价数据中。恐怕对于一般的修补匠来说，效果并不理想。他们为每件显示器报价200.00美元。控制器为每件4.50（以样品数量计）。面板的批量生产报价为60.00 / pc。当然，后者的报价取决于数量-我怀疑亚马逊的定价会更好！（顺便说一句，这是为6英寸面板，在2007年12月前后引用的）

如果您真的很认真，他们确实提供了大约3,000美元的开发套件。

鉴于该技术仍是相对较新的技术，而且许多关键技术（相对于启用技术）都受到了很多专利保护，因此我们需要一段时间才能看到商品（通用）电子墨水显示器。

报价显示的尺寸是多少？

这是一个6" ，围绕2007年12月后，我敢肯定，价格已经从那里显著下跌，而不是‘便宜’的水平我更新我的回答的正文以反映此感谢。

这是我对SeeedStudio电子墨水的经验。

http://www.picaxeforum.co.uk/showthread.php?23583-E-ink-on-PICAXE-see-it-now-！

Seeedstudio电子墨水是Arduino兼容的护罩。（但是，它与Arduino并不完全兼容！。请参见Seeedstudio论坛：http : //www.seeedstudio.com/forum/viewtopic.php? p=16432#p16432 ）

这是PICAXE代码：

Shield上实际上只有两个活动芯片，一个字符ROM和电子墨水驱动程序。

代码读取ROM以获取位模式，重新排列位，然后发送到E-ink驱动程序。

我无法在电子墨水显示器上找到任何制造商的名称，除非制造商被称为“良好显示器”！（这些是背面唯一的字样，还有零件号GDE021A1）（编辑：我只是再次搜索了零件号，这次它找到了制造商。这是好显示器！）

我的想法是，这对于正确的应用程序是完美的，我只需要找到该应用程序即可。

PervasiveDisplays 1.44"电子纸显示是13.87美元128×96个像素，111dpi，外形尺寸以毫米（8.8美元的100PC。）：40.512 X 28.80 X 1.00 http://www.pervasivedisplays.com/products/144

但是：它不像10x10mm那样小，并且可以肯定它没有那么快。但是至少现在价格要低得多。

Seeed Studio截至2013-04-16 WEST，提供Arduino 电子墨水显示屏护板，价格为49.90 USD。显示分辨率为172×72像素。PCB的占地面积为68×63 mm。从图片来看，显示组件的面积不到PCB的一半。

抱歉，如果我来晚了，请尝试SHARP低能耗显示器，它们基于像素，并且尺寸较小。Adafruit带有这些，它们的工作方式与电子墨水显示器完全相同。这些可以在原始的卵石智能手表中找到，并且使用适当的软件，它们可以惊人地工作。
