Calfee, Halter & Griswold LLP
Display substrate, in-cell touch screen, display apparatus, and touch screen driving method
An in-cell touch screen includes a pressure sensing structure. The pressure sensing structure includes a plurality of pressure sensitive electrodes arranged in an array and being independent from each other, each pressure sensitive electrode configured for generating a potential difference in response to a pressure caused by pressing; an input electrode electrically connected to the plurality of pressure sensitive electrodes for receiving a fixed potential in a pressure detection phase; and a plurality of output electrodes each electrically connected to a respective one of the plurality of pressure sensitive electrodes for outputting a signal indicative of a change in a potential of the respective pressure sensitive electrode with respect to the fixed potential in the pressure detection phase.
