【摘要】 本文设计了一种自动扫描式LED显示器。该装置包括LED线阵、显示控制模块、运动控制模块、运动与显示同步模块以及太阳能供电模块。装置的LED线阵利用太阳能供电,可在电动机带动下做匀速圆周运动,并在空间形成完整的二维图像。实验表明,该装置不仅能够有效地实现图像的连续稳定显示,而且具有节能环保和能源清洁等特点。更多还原

【Abstract】 This paper puts forward an automatic scan LED displayer.The displayer consists of LED array,display control module,movement control module,synchronization module and a solar power module.Taking advantage of the solar power,the LED linear array is in uniform circular motion driven by a motor and forms a two dimensional image.Experiments indicate that the automatic scan LED displayer can continuously produce stable images and the involvement of the solar power module makes the device cleaner,environment friendlier and more economic.更多还原
