DETECTION DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18365486 titled 'DETECTION DEVICE

Simplified Explanation

The patent application describes a detection device that includes a photodetector, a filter layer, and a display panel.

  • The filter layer is placed on top of the photodetector and is made of a first color material that allows light in a specific wavelength band to pass through.
  • The filter layer has a high peak transmittance of 90% or more, meaning it allows a large amount of light to pass through.
  • At a wavelength of 550 nm, the filter layer has a transmittance of 80% or more, indicating it still allows a significant amount of light in this range to pass through.
  • At a wavelength of 600 nm, the filter layer has a transmittance of 10% or more, meaning it allows only a small amount of light in this range to pass through.
  • At wavelengths between 680 nm and 700 nm, the filter layer has a transmittance of 10% or less, indicating it blocks most of the light in this range.
  • The display panel is arranged over the filter layer, suggesting that the device can display information or images on top of the filtered light.


Original Abstract Submitted

A detection device includes a photodetector, a filter layer overlapped on the photodetector and including a first color material having a peak transmittance for light in a first wavelength band, and a display panel arranged over the filter layer, wherein the filter layer has a peak transmittance of 90% or more, a transmittance of 80% or more at a wavelength of 550 nm, a transmittance of 10% is more at a wavelength of 600 nm, and a transmittance of 10% or less at a wavelength of 680 nm to 700 nm.
