LIGHT-EMITTING DEVICE, DISPLAY PANEL AND DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18033494 titled 'LIGHT-EMITTING DEVICE, DISPLAY PANEL AND DISPLAY APPARATUS

Simplified Explanation

The patent application describes a light-emitting device, a display panel, and a display apparatus. The device includes an anode and a cathode arranged opposite to each other, with a light-emitting function layer in between. The light-emitting function layer consists of a light-emitting layer, a first auxiliary function layer between the light-emitting layer and the anode, a second auxiliary function layer between the light-emitting layer and the cathode, and at least one co-doped layer. The co-doped layer is made by mixing materials from the adjacent film layers, where the difference in material physical properties between these film layers is greater than a set value.

  • The light-emitting device includes an anode, a cathode, and a light-emitting function layer.
  • The light-emitting function layer consists of a light-emitting layer, a first auxiliary function layer, a second auxiliary function layer, and at least one co-doped layer.
  • The co-doped layer is formed by mixing materials from the adjacent film layers.
  • The difference in material physical properties between the adjacent film layers must exceed a set value.

Potential Applications

  • Display panels for electronic devices such as smartphones, tablets, and televisions.
  • Lighting applications such as LED displays and signage.
  • Medical devices that require precise and efficient light emission.

Problems Solved

  • Improved efficiency and performance of light-emitting devices.
  • Enhanced control over the light emission process.
  • Reduction in manufacturing complexity and cost.

Benefits

  • Higher brightness and color accuracy in display panels.
  • Improved energy efficiency and longer lifespan of light-emitting devices.
  • Simplified manufacturing process and reduced production costs.


Original Abstract Submitted

A light-emitting device, a display panel and a display apparatus are disclosed. The light-emitting device includes an anode and a cathode arranged oppositely, and a light-emitting function layer located between the anode and the cathode; the light-emitting function layer includes a light-emitting layer, a first auxiliary function layer located between the light-emitting layer and the anode, a second auxiliary function layer located between the light-emitting layer and the cathode, and at least one co-doped layer; and a difference in material physical properties between two film layers adjacent to the co-doped layer is greater than a set value, and the co-doped layer includes a material formed by mixing materials of the two adjacent film layers.
