DETECTION DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18582937 titled 'DETECTION DEVICE

The patent application describes a detection device with photosensors arranged in two directions on a substrate.

  • The substrate includes read control scan lines for transmitting signals and output signal lines.
  • Dummy elements with first photodiodes are arranged along the sensor region's contour.
  • Detection elements with second photodiodes are placed inside a dummy region.
  • Dummy elements are not connected to read control scan lines or output signal lines.
  • Detection elements are connected to both read control scan lines and output signal lines.
  • Detection elements receive read control signals and output signals generated by the first photodiodes.

Potential Applications: - Image sensors - Biometric scanners - Surveillance cameras

Problems Solved: - Efficient signal transmission in sensor devices - Improved image quality in detection systems

Benefits: - Enhanced accuracy in detecting light signals - Reduced noise interference in sensor readings

Commercial Applications: - Security systems - Medical imaging devices - Industrial automation equipment

Questions about the Technology: 1. How does the arrangement of dummy and detection elements improve signal detection? 2. What advantages does the use of multiple photodiodes offer in this detection device?


Original Abstract Submitted

A detection device includes: a substrate having a sensor region in which photosensors are arranged in a first direction and a second direction. In the sensor region, the substrate includes: read control scan lines extending in the first direction and configured to transmit read control signals; and output signal lines extending in the second direction. The photosensors includes: dummy elements comprising first photodiodes and arranged along a contour of the sensor region; and detection elements comprising second photodiodes and arranged on an inner side of a dummy region in which the dummy elements are arranged. The dummy elements are coupled to neither the read control scan lines nor the output signal lines. The detection elements are coupled to the read control scan lines and the output signal lines and are configured to, after receiving the read control signals, output signals generated by the first photodiodes to the output signal lines.
