OLED belongs to a current type of organic light emitting device, also known as organic laser display, organic light emitting semiconductor. Under the action of electric field, the internal electrons of OLED will move and meet, and the energy excitons generated will excite luminescence, thereby producing visible light.
Widely used in TV, commercial display, conference display, car display, etc.
