在现代电子设备中对信息显示器件的需求日益迫切。这种需要包括从数字显示器直到全标度图表显示。传统的显示器件是阴极射线管,或许还附带,例如,机械电气数字指示器。虽然阴极射线管在显示的尺寸和灵活性方面还没有受到挑战,但在电子设备中固体电路日益普及已使人们感到它很苯重而且工作电压很高等缺点。可以直接用固体电路驱动的平板组件(flat—pack)是非常可取的。这种显示器件之一就是场致发光屏。 1907年,马可尼有限公司的H.J.Round首先报导了场致发光现象,当时是用碳化硅晶体作无线电检波实验。但是这一现象一直没有被充分研究,直到二十年代,当时Lossev开始对这一现象进行了 The demand for information display devices in modern electronic devices is becoming more and more urgent. This need includes everything from digital displays to full scale charts. Traditional display devices are cathode ray tubes, perhaps also attached, for example, mechanical and electrical digital indicators. Although cathode ray tubes have not been challenged in terms of the size and flexibility of their display, the growing popularity of solid-state electronics in electronic devices has led to the perceived shortcomings of being benign and operating at high voltages. A flat-pack that can be driven directly by a solid-state circuit is highly desirable. One such display device is a electroluminescent screen. In 1907, H.J.Round, Marconi Limited, first reported the phenomenon of electroluminescence, using radio-frequency detection of silicon carbide crystals. However, this phenomenon has not been fully studied until the 1920s, when Lossev began to carry out this phenomenon
