摘要
随着显示屏技术的不断进步，人们日常生活中越来越多地使用各种类型的显示屏。然而，这些显示屏存在着造型单一、散热性差、工作效率低、缺乏创新等问题。为了推动显示屏行业的快速发展，我们以用户需求为研究方向，设计了一款智能显示屏，旨在更好地满足人们对显示屏的需求，并引领显示屏技术的创新发展。
本文了解显示屏工作原理的基础上，采用了软硬件设计的方式进行研究。硬件部分以STC89C52单片机为核心控制器件，利用蓝牙和显示屏技术，设计一款能耗低、散热性强的显示屏，有效降低资源的浪费。本文通过手机蓝牙连接主板，实现手机APP发送显示内容的功能，通过LCD12864显示屏实现显示内容的功能，通过一对蓝牙，一个连接主板，另一个连接电脑，实现通信功能，此外，电脑还可以实现发送显示内容的功能。软件部分使用 Keil5 编程算法，进行系统程序的编写和运行，最后实现对广告显示屏的控制。通过实物测试，该广告显示屏效果较好，不仅实现合理利用资源，还起到降低成本、弥补传统显示屏缺陷的作用。

Design of intelligent advertising screen system based on single chip microcomputer
Abstract
With the continuous advancement of display screen technology, various types of display screens are increasingly being used in people’s daily lives. However, these displays suffer from problems such as monotonous design, poor heat dissipation, low work efficiency, and lack of innovation. In order to promote the rapid development of the display screen industry, we have designed an intelligent display screen based on user needs, aiming to better meet people’s demands for display screens and lead the innovation and development of display screen technology.
On the basis of understanding the working principle of the display screen, the design of hardware and software is used for research. The hardware part uses STC89C52 microcontroller as the core control device, and uses Bluetooth and display technology to design an advertising screen with low energy consumption and strong heat dissipation, effectively reducing the waste of resources. In this design, mobile APP is connected to the motherboard to realize the function of sending and displaying contents, and LCD12864 display screen to realize the function of displaying contents. Through a pair of Bluetooth, one is connected to the motherboard and the other is connected to the computer to realize the communication function. In addition, computer can also realize the function of sending and displaying contents. The software part uses Keil5 and C language programming algorithm to write and run the system program, and finally realizes the control of advertising display screen. Through the real test, the advertising display effect is good, not only to realize the rational use of resources, but also to reduce the cost, make up for the traditional display defects.
