構(gòu)造是在兩片平行的玻璃當(dāng)中放置液態(tài)的晶體，兩片玻璃中間有許多垂直和水平的細(xì)小電線，透過通電與否來控制桿狀水晶分子改變方向，將光線折射出來產(chǎn)生畫面。比CRT要好的多，但是價錢較其貴

openssl源碼 The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS) protocols as well as a full-strength general purpose cryptography library. The project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the OpenSSL toolkit and its related documentation.

頻閃有一種顯示器叫CRT，是“陰極射線顯示器”，工作原理是這樣的，利用高溫的電子發(fā)生裝置（稱為電子槍）發(fā)射大量電子束，利用強(qiáng)磁場來控制電子束的偏轉(zhuǎn)，以轟擊熒屏而產(chǎn)生亮點(diǎn)。圖像處理裝置告訴強(qiáng)磁場，哪些點(diǎn)應(yīng)當(dāng)發(fā)光，哪些點(diǎn)不發(fā)光。 如前所述，動態(tài)畫面是由一系列略有差別的幀組成的。在顯示一幀時，不是一下子完全顯示整幅圖像，而是由電子槍按照一定的路徑逐個掃射熒屏點(diǎn)的。一般是一行一行地掃下來。顯示過程是這樣的，先全黑短暫時間，再一行一行掃射下來，直到所有行都被掃射到，一幀圖像顯示完成，然后再全黑，為顯示下一幅圖像作好準(zhǔn)備。所以在某個時刻，可能一幀圖像剛剛結(jié)束，也可能才剛剛開始，也可能顯示了一半，還有可能是全黑。

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 economical price. Freescale Semiconductor gives design engineers the flexibility to choose the right 32-bit microcontroller from a broad portfolio of ColdFire? embedded controllers.

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 quality of life, enabled by a wise and participative management of natural resources to be ensured by citizens and government. The need to build smart cities became a requirement that relies on urban development that should take charge of the new infrastructures for smart cities (broadband infrastructures, wireless sensor networks, Internet-based networked applications, open data and open platforms) and provide various smart services and enablers in various domains including healthcare, energy, education, environmental management, transportation, mobility and public safety.
