场致发光屏作为大面积屏或显示器,由于种种原因,没有获得广泛的应用。一个主要的原因是,要获得命人满意的亮度,就要很大的功率。卽使功率损耗不是重要问题,但大量的功耗产生大量的热,就使得屏的各种成分迅速老化,因而使寿命缩短。所以除了一些像夜间光源一类的低功率、低亮度的器件外,其他器件未能成为市售商品。 把发光屏当作一个电容来处理,把它和正好匹配的电感接成谐振回路,并调到谐 Electroluminescent screen as a large screen or display, due to various reasons, did not get a wide range of applications. One of the main reasons is that to get satisfactory brightness, a lot of power is needed.卽 making power loss is not an important issue, but a lot of power to produce a lot of heat, making the screen quickly aging of the various components, thus reducing the life expectancy. So, except for some low-power, low-brightness devices such as nighttime light sources, other devices have failed to become commercial products. The luminescent screen as a capacitor to deal with it and just match the inductance connected resonant circuit, and tune to harmonic
