Light-emitting device
摘要:
An embodiment of the invention concerns a light-emitting device with an adjustable, time-variable luminance. This is achieved through electrically conductive tracks that are applied to the first electrode area. The conductive tracks are driven in a time-variable manner with different levels of electrical power.
