LIGHT EMITTING DISPLAY DEVICE, MANUFACTURING METHOD THEREOF, AND VEHICLE HAVING LIGHT EMITTING DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240023419 titled 'LIGHT EMITTING DISPLAY DEVICE, MANUFACTURING METHOD THEREOF, AND VEHICLE HAVING LIGHT EMITTING DISPLAY DEVICE

Simplified Explanation

According to embodiments, a light-emitting display device includes a light-emitting diode (LED) positioned on a substrate and including an emission layer, a pixel definition layer including an opening corresponding to the emission layer, and a plurality of light-shielding linear patterns positioned on the pixel definition layer and the emission layer and extending in a first direction. The plurality of light-shielding linear patterns include a recess portion of a concave shape.

  • The light-emitting display device includes a LED positioned on a substrate.
  • The LED has an emission layer.
  • The device also includes a pixel definition layer with an opening corresponding to the emission layer.
  • There are multiple light-shielding linear patterns on the pixel definition layer and the emission layer.
  • The light-shielding linear patterns extend in a first direction.
  • The light-shielding linear patterns have a recess portion with a concave shape.

Potential applications of this technology:

  • Display devices: This technology can be used in various types of display devices such as televisions, computer monitors, and mobile phone screens.
  • Signage: The light-emitting display device can be used for creating illuminated signs and billboards.
  • Automotive lighting: This technology can be applied to automotive lighting systems, including headlights and taillights.

Problems solved by this technology:

  • Light leakage: The light-shielding linear patterns help prevent light leakage and improve the contrast ratio of the display device.
  • Pixel definition: The pixel definition layer with the opening corresponding to the emission layer ensures accurate and precise pixel definition.

Benefits of this technology:

  • Improved contrast ratio: The light-shielding linear patterns enhance the display device's contrast ratio by reducing light leakage.
  • Accurate pixel definition: The pixel definition layer with the opening ensures clear and well-defined pixels on the display.
  • Versatile applications: This technology can be used in various display devices and lighting systems, providing flexibility and adaptability.
