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.

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。

So, for those who truly wish to reduce the amount of energy expended on lighting the answer may not be to ban old-fashioned incandescent bulbs, as is the current trend, but to make them compulsory.

所以，对那些实心眼儿的希望减少用于照明的能源消耗的人来说，答案可能不是像目前的趋势一样去禁止使用老式的白炽灯，而是强制性的使用它们。
