DISPLAY PANEL AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17597106 titled 'DISPLAY PANEL AND DISPLAY DEVICE

Simplified Explanation

The patent application describes a display panel and a display device. The display panel consists of a substrate, a light emitting layer, a protective layer, and a light adjusting layer. The protective layer is located on the side of the light emitting layer opposite to the substrate and includes multiple stop blocks that correspond to the gaps between light emitting pixels. The light adjusting layer is situated between adjacent stop blocks and covers them. The refractive index of the protective layer is lower than that of the light adjusting layer, causing total reflection of light at the junction between the light adjusting layer and the stop block. This design enhances forward light efficiency and light output efficiency.

  • The display panel includes a protective layer with stop blocks and a light adjusting layer.
  • The protective layer is positioned on the side of the light emitting layer away from the substrate.
  • The stop blocks in the protective layer correspond to the gaps between light emitting pixels.
  • The light adjusting layer is located between adjacent stop blocks and covers them.
  • The refractive index of the protective layer is lower than that of the light adjusting layer.
  • Total reflection of light occurs at the junction between the light adjusting layer and the stop block.
  • This configuration improves forward light efficiency and light output efficiency.

Potential Applications

  • Display panels for electronic devices such as smartphones, tablets, and televisions.
  • Signage and advertising displays.
  • Automotive displays and instrument clusters.

Problems Solved

  • Low forward light efficiency and light output efficiency in display panels.
  • Inefficient use of light emitted by the light emitting layer.
  • Light loss and scattering due to gaps between light emitting pixels.

Benefits

  • Improved forward light efficiency and light output efficiency.
  • Enhanced brightness and clarity of displayed content.
  • Reduced energy consumption and longer battery life for portable devices.
  • Better visibility and readability in various lighting conditions.


Original Abstract Submitted

A display panel and a display device are disclosed. The display panel includes a substrate, a light emitting layer, a protective layer and a light adjusting layer. The protective layer is located on the side of the light emitting layer far away from the substrate, the protective layer includes a plurality of stop blocks disposed corresponding to gaps between light emitting pixels, and the light adjusting layer is located between adjacent two stop blocks and covers the stop blocks. A refractive index of the protective layer is less than a refractive index of the light adjusting layer, and the light is totally reflected at a junction between the light adjusting layer and the stop block, which improves the forward light efficiency and light output efficiency.
