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

This abstract first appeared for US patent application 20240049553 titled 'DISPLAY DEVICE AND ELECTRONIC DEVICE

Simplified Explanation

The abstract describes a display device with a specific arrangement of pixels and light emitting elements. Each pixel has two light emitting elements and a color filter layer. The first light emitting element has a color filter and its opening is defined by the color filter layer. The second light emitting element has a different color filter with a different spectral transmittance characteristic. The size ratio of the opening to the light emitting region of the first light emitting element is smaller in the second pixel compared to the first pixel.

  • The display device has a central portion where the first pixel is located and a second pixel arranged between the first pixel and the edge of the display region.
  • Each pixel consists of two light emitting elements and a color filter layer.
  • The first light emitting element has a color filter and its opening is defined by the color filter layer.
  • The second light emitting element has a different color filter with a different spectral transmittance characteristic.
  • The size ratio of the opening to the light emitting region of the first light emitting element is smaller in the second pixel compared to the first pixel.

Potential Applications:

  • This display device technology can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
  • It can enhance the visual quality and color accuracy of displays, providing a more vibrant and realistic viewing experience.

Problems Solved:

  • The arrangement of pixels and light emitting elements helps to improve color accuracy and reduce color bleeding or cross-talk between adjacent pixels.
  • The different color filters in the light emitting elements allow for better control of color reproduction and accuracy.

Benefits:

  • Improved color accuracy and vibrancy in displays.
  • Reduced color bleeding or cross-talk between pixels.
  • Enhanced visual quality and realism in electronic devices.


Original Abstract Submitted

display device has display region of pixels including first pixel arranged in central portion of the display region and second pixel arranged between the first pixel and the edge of the display region. each pixel includes first and second light emitting elements. color filter layer is arranged on the first and second light emitting elements. the first light emitting element includes first color filter, and opening of the first light emitting element is defined by the color filter layer. the second light emitting element includes second color filter and having spectral transmittance characteristic different from the first color filter. ratio of size of the opening to size of light emitting region of the first light emitting element is smaller in the second pixel than in the first pixel.
