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

This abstract first appeared for US patent application 17898543 titled 'LED DISPLAY PANEL AND DISPLAY DEVICE

Simplified Explanation

The abstract describes a patent application for an LED display panel that includes a substrate, a light source assembly, and a light filter layer. The light filter layer has a light-transmitting region and a non-light-transmitting region. The incident angle of the light emitted by the light source assembly to the light-transmitting region is less than the total reflection critical angle of the light filter layer, while the incident angle to the non-light-transmitting region is greater than or equal to the total reflection critical angle.

  • The LED display panel includes a substrate, a light source assembly, and a light filter layer.
  • The light filter layer has a light-transmitting region and a non-light-transmitting region.
  • The incident angle of the light emitted by the light source assembly to the light-transmitting region is less than the total reflection critical angle of the light filter layer.
  • The incident angle of the light emitted by the light source assembly to the non-light-transmitting region is greater than or equal to the total reflection critical angle of the light filter layer.

Potential applications of this technology:

  • LED display panels can be used in various electronic devices such as televisions, computer monitors, and smartphones.
  • The light filter layer can improve the display quality and visibility of the LED panel by controlling the angle of light transmission.

Problems solved by this technology:

  • The light filter layer helps to prevent total internal reflection, which can cause loss of light and reduce the efficiency of the LED display panel.
  • By controlling the incident angles of light, the technology ensures that light is transmitted through the desired regions of the display panel, improving the overall display performance.

Benefits of this technology:

  • Improved display quality and visibility due to controlled light transmission.
  • Enhanced efficiency of the LED display panel by reducing light loss through total internal reflection.
  • Increased versatility and applicability of LED display panels in various electronic devices.


Original Abstract Submitted

A LED display panel includes a substrate, a light source assembly disposed on the substrate, and a light filter layer disposed on the light source assembly. The light filter layer includes a light filter region. The light filter region includes a light-transmitting region and a non-light-transmitting region disposed outside the light-transmitting region. An incident angle of a light emitted by the light source assembly to the light-transmitting region is less than a total reflection critical angle of the light filter layer, and an incident angle of the light emitted by the light source assembly to the non-light-transmitting region is greater than or equal to the total reflection critical angle of the light filter layer. The total reflection critical angle is a critical angle at which the light exits from an upper surface of the light filter layer. A display device includes the LED display panel.
