DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18191391 titled 'DISPLAY DEVICE

Simplified Explanation

The patent application describes a display apparatus that includes different types of sub-pixels and a multi-layered structure to achieve color conversion and filtering. The display apparatus utilizes organic light-emitting diodes (OLEDs) with multiple emission layers and quantum dots to convert incident light into different colors.

  • The display apparatus includes first, second, and third sub-pixels, each capable of emitting light of different colors.
  • An organic light-emitting diode (OLED) with at least two emission layers is used to emit light of different colors.
  • A color conversion layer is placed over the first sub-pixels and contains quantum dots that convert incident light into light of a specific color.
  • A first color filter is placed over the color conversion layer to further refine the color output.
  • A first transmission layer is placed over the second sub-pixels, followed by a second color filter to achieve a different color output.
  • A second transmission layer is placed over the third sub-pixels, followed by a third color filter to achieve yet another color output.
  • The material used for the first and second transmission layers is the same, providing consistency in the display's performance.

Potential applications of this technology:

  • High-quality displays for televisions, smartphones, tablets, and other electronic devices.
  • Enhanced color accuracy and vibrancy in digital signage and advertising displays.
  • Improved color reproduction in medical imaging and professional photography.

Problems solved by this technology:

  • Achieving accurate and vibrant colors in displays with multiple sub-pixels.
  • Enhancing color conversion efficiency using quantum dots.
  • Maintaining consistency in color output across different sub-pixels.

Benefits of this technology:

  • Improved color accuracy and vibrancy in displays.
  • Enhanced visual experience for users.
  • Greater flexibility in designing displays with different color outputs.


Original Abstract Submitted

A display apparatus includes first sub-pixels, second sub-pixels, and third sub-pixels, an organic light-emitting diode including at least two emission layers emitting light of different colors, a color conversion layer disposed over the first sub-pixels and including quantum dots converting incident light into light of a first color, a first color filter disposed over the color conversion layer, a first transmission layer disposed over the second sub-pixels, a second color filter disposed over the first transmission layer, a second transmission layer disposed over the third sub-pixels, and a third color filter disposed over the second transmission layer, wherein a material of the first transmission layer is a same material as the second transmission layer.
