构造是在两片平行的玻璃当中放置液态的晶体，两片玻璃中间有许多垂直和水平的细小电线，透过通电与否来控制杆状水晶分子改变方向，将光线折射出来产生画面。比CRT要好的多，但是价钱较其贵

频闪有一种显示器叫CRT，是“阴极射线显示器”，工作原理是这样的，利用高温的电子发生装置（称为电子枪）发射大量电子束，利用强磁场来控制电子束的偏转，以轰击荧屏而产生亮点。图像处理装置告诉强磁场，哪些点应当发光，哪些点不发光。 如前所述，动态画面是由一系列略有差别的帧组成的。在显示一帧时，不是一下子完全显 ...

V1.16 Win32 July 2012 - Ported to Win32 C++ - Allow multiple instances of libnids to coexist in the same process - Incorporate unofficial patch to track established TCP connections - Migration of calls to secure versions (i.e. strcpy to strcpy_s) - Compiles under Visual Studio 2010 with no warnings ...

Connecting 32-bit controlled applications in the industrial, commercial and consumer markets is fast becoming a necessity rather than an option. Many new applications, such as remote data collection, home automation and networked appliances, require secure, high-performance connectivity at an econom ...

玩老游戏机用，让液晶有crt的感觉。当然，最终效果跟crt还是有差别的。

The concept of smart cities emerged few years ago as a new vision for urban development that aims to integrate multiple information and communication technology (ICT) solutions in a secure fashion to manage a city’s assets. Modern ICT infrastructure and e-services should fuel sustainable growth and ...
