DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18260876 titled 'DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS

Simplified Explanation

The patent application describes a display panel and a manufacturing method for the panel, as well as a display apparatus. The display panel includes a hole transport layer, a buffer layer with first and second sub-pixels, a light-emitting layer, and a cathode. The HOMO energy levels of the buffer sub-layers gradually increase towards the light-emitting layer.

  • The display panel includes a buffer layer with first and second sub-pixels.
  • The HOMO energy level difference between the first light-emitting layer and the first hole transport layer is a specific value.
  • The absolute value of the HOMO energy level difference between the second light-emitting layer and the second hole transport layer is within a certain range.
  • The HOMO energy levels of the buffer sub-layers increase towards the light-emitting layer.
      1. Potential Applications

      1. Problems Solved

- Improved energy efficiency in display panels - Enhanced image quality and color accuracy

      1. Benefits

- Higher performance and efficiency in display technology - Better color reproduction and image clarity


Original Abstract Submitted

A display panel and a manufacturing method therefor, and a display apparatus. The display panel includes: a hole transport layer; a buffer layer, including at least one of first and second buffer layers respectively in first and second sub-pixels; a light-emitting layer, HOMO energy level difference between the first light-emitting layer and the first hole transport layer being a first difference, and absolute value of HOMO energy level difference between the second light-emitting layer and the second hole transport layer being greater than 0 and less than the first difference; and a cathode. HOMO energy levels of first buffer sub-layers gradually increase in the direction from the first hole transport layer to the first light-emitting layer. HOMO energy level difference between the second light-emitting layer and the second buffer layer or the second buffer layer and the second hole transport layer is greater than or equal to 0.3 eV.
