【摘要】： 隨著科學技術的發(fā)展,如今半導體發(fā)光二極管的性能達到了更高的水平。半導體發(fā)光器件耗電量小且發(fā)光效率高,尤其藍色超高亮LED的出現(xiàn),使得LED器件的光譜覆蓋了全部自然光的范圍,其應用也擴展到了制作全彩色大型平板顯示系統(tǒng),并受到廣泛關注。用LED器件組成電子顯示屏,不但色彩絢麗而且其制作尺寸幾乎不受限制,可以達到幾十甚至幾百平方米以上,可應用于室內外各種公共場合顯示文字、圖形、圖像、動畫、視頻圖像等信息,具有較強的廣告渲染力和震撼力,美化和豐富了人們的生活環(huán)境。 傳統(tǒng)LED顯示系統(tǒng)的控制以單片機為核心,功能較為簡單,當需要進行數(shù)據處理時,單片機的處理能力就更顯不足,不能滿足LED顯示屏發(fā)展的需要。本文將介紹一種基于CPLD控制平臺的LED全彩色顯示屏控制系統(tǒng)。論文首先介紹了LED顯示技術和系統(tǒng)設計,然后詳細介紹了系統(tǒng)的高速數(shù)據傳輸部分和數(shù)據接收部分的實現(xiàn)過程。根據數(shù)據傳輸?shù)乃俾室蠛蚅ED屏箱體間的連接特點,本文設計了兩種傳輸方案。第一種,使用HDMP-1022和HDMP-1024專用傳輸芯片的設計方案;另外一種為采用LVDS技術配合驅動和均衡器來實現(xiàn)傳輸要求的解決方案。此外,論文還對分控板的系統(tǒng)結構作了詳細的介紹,并著重描述了采用CPLD-EPM570完成主控任務的設計過程。經過對整個系統(tǒng)進行軟件仿真和硬件實驗的結果表明,該設計合理、功能完備,能夠完成600Mbps的傳輸速率,并在分控板的控制下將圖像信息在LED燈板上完整地顯示,達到了設計的要求。
[Abstract]:With the development of science and technology, the performance of semiconductor light-emitting diodes has reached a higher level.Semiconductor light-emitting devices have low power consumption and high luminous efficiency, especially the appearance of blue ultra-bright LED, which makes the spectrum of LED devices cover the whole range of natural light, and its application also extends to making full-color flat panel display system.And received extensive attention.The electronic display screen composed of LED devices is not only colorful, but also almost unlimited in size, and can be used to display text, graphics, images, animation in and out of the room in various public places, even more than a few hundred square meters.Video images and other information, with strong advertising rendering power and shock, beautify and enrich people's living environment.The control of traditional LED display system is based on single chip microcomputer, and its function is relatively simple. When data processing is needed, the processing ability of single chip microcomputer is even less than that of single chip computer, which can not meet the needs of the development of LED display screen.This paper introduces a LED full color display control system based on CPLD control platform.This paper first introduces the LED display technology and system design, and then introduces the implementation of the high-speed data transmission and data receiving part in detail.According to the speed requirement of data transmission and the connection characteristics of LED display box, two transmission schemes are designed in this paper.The first is the design of the special transmission chip using HDMP-1022 and HDMP-1024, and the other is the solution to realize the transmission requirement by using the LVDS technology to cooperate with the driver and equalizer.In addition, the system structure of the sub-control board is introduced in detail, and the design process of using CPLD-EPM570 to accomplish the main control task is described emphatically.The software simulation and hardware experiment of the whole system show that the design is reasonable, the function is complete, the transmission rate of 600Mbps can be completed, and the image information is displayed on the LED lamp board under the control of the sub-control board.Meet the design requirements.
