SENSING CIRCUIT, DISPLAY DEVICE INCLUDING SENSING CIRCUIT, AND METHOD OF DRIVING SENSING CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18195684 titled 'SENSING CIRCUIT, DISPLAY DEVICE INCLUDING SENSING CIRCUIT, AND METHOD OF DRIVING SENSING CIRCUIT

Simplified Explanation

The sensing circuit described in the patent application includes several components that enable the sampling of sensing voltages and noise in different sub-sensing periods. Here is a simplified explanation of the abstract:

  • The circuit has a first line selection switch that connects a first sensing line to a sensing channel in the first sub-sensing period.
  • It also has a first noise selection switch that connects the first sensing line to a reference channel in the second sub-sensing period.
  • A second line selection switch connects a second sensing line to the sensing channel in the second sub-sensing period.
  • A second noise selection switch connects the second sensing line to the reference channel in the first sub-sensing period.
  • The sensing channel samples the first sensing voltage and noise of the first sensing line, while the reference channel samples noise from the second sensing line in the first sampling period.
  • In the second sampling period, the sensing channel samples the second sensing voltage and noise of the second sensing line, while the reference channel samples noise from the first sensing line.

Bullet points explaining the patent/innovation:

  • The circuit allows for the sampling of sensing voltages and noise in different sub-sensing periods.
  • It includes line selection switches that connect the sensing lines to the sensing channel and the reference channel.
