Abstract:
An organic light emitting diode (OLED) comprising:a bottom substrate comprising a bottom electrode positioned on an upper surface of the bottom substrate, an organic layer positioned on the bottom electrode, a top electrode positioned on the organic layer, and a spot glue region positioned on the bottom substrate and outside the organic layer, an upper surface of the bottom electrode comprising at least one first ditch; a top substrate positioned parallel with the bottom substrate, and a lower surface of the top substrate comprising at least one second ditch formed within the top substrate; and a sealing material positioned on the spot glue region of the bottom substrate for binding the top substrate and the bottom substrate together; wherein the first ditch and the second ditch are used to prevent the sealing material from overflowing into the region occupied by the organic layer and affecting normal operation of the OLED.
