DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18349943 titled 'DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME

Simplified Explanation

The patent application describes a display device with a light-emitting element and a touch sensor.

  • The display device includes a light-emitting element that is connected to a driving element.
  • An encapsulation layer covers the light-emitting element to protect it.
  • A touch sensor is placed on top of the encapsulation layer for touch input.
  • The device also includes a connection pad with multiple conductive layers for electrical connections.
  • A cladding layer made of organic material covers the side surface of one of the conductive layers.
  • A passivation layer made of inorganic material covers the cladding layer and is located under another conductive layer.
  • A driving circuit is attached to the connection pad to control the display device.


Original Abstract Submitted

A display device includes: a light-emitting element at a display area; a driving element electrically connected to the light-emitting element; an encapsulation layer covering the light-emitting element; a touch sensor on the encapsulation layer; a connection pad at a bonding area, the connection pad including a lower conductive layer, an intermediate conductive layer on the lower conductive layer, and an upper conductive layer on the intermediate conductive layer; a cladding layer covering at least a side surface of the intermediate conductive layer and including an organic material; a passivation layer covering an upper surface of the cladding layer and including an inorganic material, a portion of the passivation layer being located under the upper conductive layer; and a driving circuit attached to the connection pad.
