COLOR FILTER SUBSTRATE AND ORGANIC LIGHT-EMITTING DISPLAY PANEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240016021 titled 'COLOR FILTER SUBSTRATE AND ORGANIC LIGHT-EMITTING DISPLAY PANEL

Simplified Explanation

The patent application describes a color filter substrate and an organic light-emitting display panel. The color filter substrate is rectangular in shape and has an upper side, a lower side, a left side, and a right side. The lower side corresponds to a driving chip of the organic light-emitting display panel. The color filter substrate includes a light-shielding layer with multiple light-transmitting holes arranged in an array. The openings of the light-transmitting holes gradually become smaller from the upper side to the lower side.

  • The color filter substrate is rectangular in shape with a light-shielding layer and light-transmitting holes.
  • The openings of the light-transmitting holes gradually become smaller from the upper side to the lower side.
  • This design allows for a gradual reduction in the aperture ratio of the light-shielding layer from the upper side to the lower side.
  • The purpose of this design is to compensate for uneven chroma and brightness in the organic light-emitting display panel.
  • By improving the uniformity of chroma and brightness, the overall display quality is enhanced.

Potential applications of this technology:

  • This technology can be used in various electronic devices that utilize organic light-emitting display panels, such as smartphones, tablets, and televisions.
  • It can also be applied in automotive displays, wearable devices, and other display systems that require high-quality color reproduction.

Problems solved by this technology:

  • Uneven chroma and brightness in organic light-emitting display panels can result in a poor visual experience for users.
  • This technology addresses this issue by gradually reducing the aperture ratio of the light-shielding layer, compensating for the unevenness and improving the uniformity of chroma and brightness.

Benefits of this technology:

  • Improved uniformity of chroma and brightness in organic light-emitting display panels.
  • Enhanced visual experience for users.
  • Higher quality color reproduction in electronic devices.
  • Potential for increased market demand for devices utilizing this technology.


Original Abstract Submitted

a color filter substrate and an organic light-emitting display panel are disclosed. the color filter substrate is rectangular and has an upper side, a lower side, a left side, and a right side, wherein, the lower side corresponds to a driving chip of the organic light-emitting display panel. the color filter substrate includes a light-shielding layer defined with a plurality of light-transmitting holes arranged in an array, and from the upper side to the lower side, openings of the light-transmitting holes are gradually smaller. the present disclosure allows an aperture ratio of the light-shielding layer to be gradually reduced from the upper side that is away from the driving chip to the lower side that corresponds to the driving chip. therefore, an area of the organic light-emitting display panel having uneven chroma and brightness can be compensated, thereby improving uniformity of the chroma and brightness.
