固態(tài)繼電器已廣泛應(yīng)用于計(jì)算機(jī)-接口設(shè)備、恒溫系統(tǒng)、調(diào)溫、電爐加溫控制、電機(jī)控制、數(shù)控機(jī)械等等
電源開關(guān)就是用通過電路控制開關(guān)管進(jìn)行高速的道通與截止．將直流電轉(zhuǎn)化為高頻率的交流電提供給變壓器進(jìn)行變壓，從而產(chǎn)生所需要的一組或多組電壓！

ledlight emitting diode，發(fā)光二極管，是一種能夠?qū)㈦娔苻D(zhuǎn)化為可見光的固態(tài)的半導(dǎo)體器件，它可以直接把電轉(zhuǎn)化為光。
背光源按光源類型主要有el、ccfl及l(fā)ed三種背光源類型，依光源分布位置不同則分為側(cè)光式和直下式底背光式。以下是它們的簡單介紹。
