表盘被制造成具有只有当LED被接通时才可以通过表盘看见LED的数字显示的光透射率。
Only when the LED is turned on, the dial is formed with such light transmittance that the digital display of the LED can be viewed through the dial.
在接收系统中,引进窄带干涉滤光片,减少背景光的干扰,增加信号光透射率,改善信噪比。
In the receiving system, the narrow-band interference filter is introduced in order to reduce the background light, increase the signal transmission rate, and improve the signal-to-noise ratio.
液晶面板的光透射率极低,要产生电视需要的显示亮度就需要背光提供足够的光强,背光系统需要消耗较多的电能。
LCD TV panels of light transmittance is very low, to produce TV backlight brightness the display needed will need to provide adequate light intensity, and backlight system needs to consume more power.
