INPUT SENSING DEVICE AND A DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18092504 titled 'INPUT SENSING DEVICE AND A DISPLAY DEVICE INCLUDING THE SAME

Simplified Explanation

The patent application describes an input sensing device that includes various components such as power lines, driving lines, signal lines, and sensor pixels.

  • The device has a power line for providing power to the sensor pixels.
  • It has driving lines that are used to send driving signals to the sensor pixels.
  • The first signal line consists of sub-lines, and there is a second signal line connected to these sub-lines.
  • The sensor pixels are connected to the power line, driving lines, and the first signal line.

The patent application also explains the structure and functioning of at least one sensor pixel:

  • Each sensor pixel includes an optical sensor that converts light into an electrical charge.
  • This charge is transferred from the power line to a first node in response to a driving signal provided through a first driving line.
  • The sensor pixel also includes two transistors connected between the first node and different sub-lines.
  • The first transistor has a gate electrode connected to the first driving line and is connected to a first sub-line.
  • The second transistor has a gate electrode connected to the first driving line and is connected to a second sub-line.

Potential applications of this technology:

  • Input sensing devices can be used in various electronic devices such as touchscreens, cameras, and scanners.
  • This technology can improve the accuracy and responsiveness of input devices, leading to better user experiences.

Problems solved by this technology:

  • The input sensing device described in the patent application provides a simplified and efficient way of transferring photoelectrically converted charges.
