摘要：自从半导体发光二极管问世以来，LED的研发和应用成了现代显示技术的核心问题，随着LED工艺的不断完善和提高，无论是大型商业广告的屏幕，还是交通信号灯都有着它的身影。作为显示领域应用最为广泛的产品，LED无论是在材料技术还是在工艺性能方面都有着优于同类照明和显示材料的优点，目前，对半导体材料的研究仍在大步向前，相信未来还会在材料和工艺方面有更大的突破。

本文提出了一种应用LED设计图案显示模型的方案，即通过一些理论知识和必要的生活常识设计出能在夜晚发光的自行车轮LED灯的装置，固定在自行车车轮的辐条上就可以显示自己所设计的精美图案。文章在简要介绍LED在显示领域的发展和应用的基础上，详细说明了显示方案在器件选型和系统的总体结构设计，以及具体硬件电路和软件设计流程。在这个设计的过程中，本文还给出了一些方面上的进一步改进和完善的思路和设想。在实际制作过程中及最后的测试结果中来看，本文设计和制作的LED图案显示装置符合任务书设计要求，总体具有一定的创新和实际应用价值。

LED在显示领域的应用开发还有很大潜力，怎样更高效更环保地加以利用是各大公司及科研部门在未来竞争的巨大动力，相信不久之后，LED必将成为显示领域不可或缺的一部分。

Abstract：Since the advent of semiconductor light-emitting diodes, LED has been developed and applied to the core of modern display technology, with the constant improvement of LED technology and improve, whether it's a large screen of commercial advertising or traffic light has its shadow.For displaying the most widely applied in the field of products, LED in both materials technology and the process performance is superior to similar lighting and shows the advantages of material, at present, the study of semiconductor materials is still in the big step forward, believe the future will have greater breakthrough in the field of material and process.

This paper proposes a design for application of the LED display model, through some theoretical knowledge and the necessary life common sense can design LED lights glowing in the night bicycle wheel device, fixed on the bicycle wheel spokes can display their design exquisite patterns.Based on the brief introduction to the LED on the basis of the development and application in the field of display, display scheme is described in detail in the device and the system's overall structure design, and the specific hardware circuit and software design process.In the process of this design, this paper also gives some aspects of further improvement and the idea of the system.In the actual production process and the final test results, this paper design and production of   LED   display   device   design   conform   to   the   requirements   of    the specification design,  overall  has certain innovation and practical  application value.

LED application development has great potential in the field of display, what use could be made more efficient and environmentally sound manner is companies and scientific research departments in the future competition of the great power, believe that soon after, the LED will become an integral part of the display field.

Keywords: 51-microcomputer; LEDSingle Row Display; Persistence of Vision; Bicycle Dazzle Light。
