The development of Internet technology promotes the intelligent development of society. In this paper，the LED smart glass display design，which combines Android embedded technology and Inter⁃ net technology，realizes the real-time interaction between people and screen. This system adopts CPU+ FPGA dual-core architecture equipped with Android operating system. Through the development of Android system application software，the wireless network is used to realize the communication between the LED smart glass display and the mobile terminal. Based on the Android system source code，this system addsthe LCD display driverand mapping data transmission driverusing the "bus-device-driver"model. Device tree is used to describe device information，which reduces a lot of code redundancy. JNI method is written in Android system for Android application program to call. Java language is used for Android system application software development；Socket network programming is used to realize the network com⁃ munication between LED smart glass display and mobile terminal. This system has good ease of use and portability，which brings convenience to product application and improves construction efficiency. [ABSTRACT FROM AUTHOR]
互联网技术的发展，促使社会向智能化发展，本文提出将Android嵌入式技术和互联网技术相结合的LED智能玻 璃显示设计，实现用户与显示屏之间实时互动。本系统采用搭载Android操作系统的CPU+FPGA双核架构，通过开发 Android系统应用软件，使用无线网来实现LED智能玻璃显示屏与移动终端的网络通信。在Android系统源码的基础上 增加了采用“总线-设备-驱动”模型构建的LCD显示驱动以及映射数据发送驱动，采用设备树描述设备信息，减少了大量 代码冗余，并在Android系统中编写JNI方法供Android应用程序调用；采用Java语言进行Android系统应用软件开发； 使用Socket网络编程来实现LED智能玻璃显示屏与移动终端的网络通信。此系统具有较好的易用性和可移植性，给产 品应用带来了方便，提高了施工效率。 [ABSTRACT FROM AUTHOR]
