英国的威廉·约翰逊与英国拉夫堡大学一研究小组,历经九载研制成可悬挂壁上的显示屏幕。 发明人认为,该投影系统有可能大规模生产。通常,人们总是设法通过使用更多的微小彩色光点(即彩色象素)的办法来获得清晰的图象。但此法有局限性,因为控制光点的“连线”最 William Johnson, from the UK, and a research group at Loughborough University in the UK have developed a display screen that can be hung on the wall after nine years of research. The inventor believes that this projection system is likely to be mass-produced. In general, people always try to get a clear picture by using more tiny color spots (ie, color pixels). However, this method has limitations, because the control point of the “connection” the most
