国内外对发光二极管单片式、混合式矩阵显示装置正在进行活跃的研究。成为这种二极管显示装置的基本技术有:制备高效率p-n结;在单一晶体基板上制作多个发光元件的集成化技术;把多个发光二极管组装起来的电气联结技术以及最佳的取光结构等。 近年来,由于GaAsP、GaP发光二极管的效率显著提高;集成化技术、组装技术的进展以及结构上的巧妙设计;用发光二极管显示装置部分地取代阴极射线管显示的可能性日趋增大起来。 本文研究了发光二极管平面显示装置的电视图像显示及文字、数字——符号显示的特性;并论述了作者最近试制的GaP绿色发光二极管平面显示装置的结构、特性及在电视显示、符号显示上的应用。
Domestic and foreign light-emitting diode monolithic, hybrid matrix display device is under active research. The basic technologies for forming such a diode display device include: an efficient pn junction; an integrated technology for fabricating a plurality of light-emitting elements on a single crystal substrate; an electrical connection technique for assembling a plurality of light-emitting diodes and an optimum light extraction structure Wait. In recent years, due to the GaAsP and GaP LEDs, the efficiency of GaAs LEDs has been significantly improved. The integration technology, the progress of assembly technology and the structural ingenious design have been greatly improved. The possibility of partial replacement of cathode ray tube displays by light-emitting diode display devices has been increasing. In this paper, we study the display characteristics of TV images and characters, figures and symbols of LED flat display devices. We also discuss the structure and characteristics of GaP green LED flat display devices recently manufactured by the author and their applications in television display and symbol display application.
