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

This abstract first appeared for US patent application 17590501 titled 'DISPLAY DEVICE AND METHOD FOR MANUFACTURING DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device with three pixels, each consisting of electrodes, sub-light emitting portions, charge generation layers, and sub-light emitting portions. The second sub-light emitting portion includes a hole transport layer and an emission layer. The hole transport layer of the first pixel completely covers the charge generation layer of the first pixel and overlaps with the charge generation layer of the second pixel.

  • The display device includes three pixels with specific layers and electrodes.
  • The second sub-light emitting portion of each pixel has a hole transport layer and an emission layer.
  • The hole transport layer of the first pixel covers the charge generation layer of the first pixel and overlaps with the charge generation layer of the second pixel.

Potential Applications

  • This display device technology can be applied in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
  • It can enhance the visual quality and resolution of the display, providing a better user experience.

Problems Solved

  • The display device solves the problem of achieving high-quality and high-resolution displays by utilizing specific layers and electrodes.
  • The overlapping of the hole transport layer with the charge generation layer improves the efficiency and performance of the display.

Benefits

  • The display device offers improved visual quality and resolution, resulting in sharper and more vibrant images.
  • It enhances the overall user experience by providing a clear and detailed display.
  • The overlapping of layers improves the efficiency and performance of the display, leading to energy savings and longer battery life.


Original Abstract Submitted

A display device includes a first pixel, a second pixel, and a third pixel each of which includes a first electrode on a substrate, a first sub-light emitting portion on the first electrode, a first charge generation layer on the first sub-light emitting portion, a second sub-light emitting portion on the first charge generation layer, and a second electrode on the second sub-light emitting portion. The second sub-light emitting portion includes a hole transport layer on the first charge generation layer and an emission layer on the hole transport layer. The hole transport layer of the first pixel is on the first charge generation layer of the first pixel and completely covers the first charge generation layer of the first pixel. A part of an edge of the hole transport layer of the first pixel overlaps the first charge generation layer of the second pixel.
