WIRING SUBSTRATE AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17963659 titled 'WIRING SUBSTRATE AND DISPLAY DEVICE INCLUDING THE SAME

Simplified Explanation

The patent application describes a display device that includes a first substrate with a display area and a pad area, conductive layers, a via layer, electrodes, insulating layers, light-emitting elements, and connecting electrodes.

  • The display device includes a first substrate with a display area and a pad area.
  • The first substrate has conductive layers with wires and conductive patterns in the display area and the pad area.
  • A via layer is present on the conductive layers.
  • The display area has first and second electrodes that are spaced apart from each other.
  • A first insulating layer is present on the first and second electrodes.
  • Light-emitting elements are located on the first and second electrodes and the first insulating layer.
  • A first connecting electrode is on the first electrode and in contact with the light-emitting elements.
  • A second connecting electrode is on the second electrode and in contact with the light-emitting elements.
  • At least one of the conductive layers includes a metal layer made of a copper-silver (CuAg) alloy with a crystal grain size of 140 nm or less.

Potential applications of this technology:

  • Display devices for electronic devices such as smartphones, tablets, and televisions.
  • Signage and advertising displays.
  • Automotive displays and instrument panels.

Problems solved by this technology:

  • Improved conductivity and reliability of the display device.
  • Enhanced performance and lifespan of the light-emitting elements.
  • Reduction in power consumption and heat generation.

Benefits of this technology:

  • Higher quality and resolution of the display.
  • Longer lifespan and durability of the display device.
  • Lower energy consumption and improved efficiency.


Original Abstract Submitted
