由于有机发光二极管本身能通过电流使有机化合物发光，不需要背光照明，因此可以做得比液晶显示器更轻、更薄，更有柔韧性。

Because OLEDs do not need to be backlit-they get their lighting from organic compounds that emit light in response to electric current-they can be thinner, lighter and more flexible than LCDs.

光线强度的变化(如光束被遮断或是一般照明的降低)会造成侦测器里产生的电流随著改变。

As the intensity of light varies - by the breaking of a light beam, say, or a decrease in general illumination - the amount of current generated by the sensor changes.

照明装置可包括输送脉冲或 热补偿脉冲电流至光源的电路。

The lighting device may include a circuit that delivers a pulsed or thermally compensated pulsed current to the light source.
