Automatic actuation of device according to UV intensity

摘要

A thin-film electro-luminescence display includes a light-emitting layer for emitting light in response to an alternate current voltage; a back electrode layer disposed at a side of the light-emitting layer; and a light-transmitting conductive layer disposed at another side of the light-emitting layer opposite to the back electrode layer, and cooperating with the back electrode layer to provide the alternate current voltage for the light-emitting layer. The light-emitting layer and the light-transmitting conductive layer are patterned to define a plurality of independent display zones, and when the alternate current voltage is applied between the back electrode layer and the light-transmitting conductive layer in a specified portion of the display zones, light is emitted by the light-emitting layer in the specified portion of display zones to show a specific character.
