DISPLAY DEVICE AND METHOD OF PROVIDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240023414 titled 'DISPLAY DEVICE AND METHOD OF PROVIDING THE SAME

Simplified Explanation

The patent application describes a display device that includes a circuit array layer and a light emitting array layer. The circuit array layer has two organic insulating layers on a pixel driving circuit, while the light emitting array layer has an organic insulating material pixel defining layer and a cathode electrode on top of it. There is a gas blocking thickness portion in a layer among the first organic insulating material planarization layer, the second organic insulating material planarization layer, and the organic insulating material pixel defining layer, which extends from the surface closest to the cathode electrode.

  • The display device includes a circuit array layer and a light emitting array layer.
  • The circuit array layer has two organic insulating layers on a pixel driving circuit.
  • The light emitting array layer has an organic insulating material pixel defining layer and a cathode electrode on top of it.
  • There is a gas blocking thickness portion in a layer among the first organic insulating material planarization layer, the second organic insulating material planarization layer, and the organic insulating material pixel defining layer.
  • The gas blocking thickness portion extends from the surface closest to the cathode electrode.

Potential applications of this technology:

  • Display devices in electronic devices such as smartphones, tablets, and televisions.
  • OLED (organic light-emitting diode) displays for improved image quality and energy efficiency.

Problems solved by this technology:

  • Gas blocking thickness portion prevents gas penetration, which can degrade the performance and lifespan of the display device.
  • Organic insulating layers and materials provide insulation and protection for the underlying circuitry and light-emitting components.

Benefits of this technology:

  • Improved display performance and lifespan due to the gas blocking thickness portion.
  • Enhanced image quality and energy efficiency with the use of OLED technology.
  • Protection of the circuitry and light-emitting components with organic insulating layers and materials.
