Fingerprint identification method for panel, electronic device, and control circuit
Abstract:
Provided are a fingerprint identification method for a panel, an electronic device and a control circuit. The method includes setting voltages on the data lines and sensing lines that may affect a fingerprint identification result to a predetermined DC voltage during a predetermined time period before a start of a fingerprint identification period that follows a display driving period. As such, when a display driving operation and a fingerprint identification operation are performed in a time-division manner, the influence of the display driving operation on the fingerprint identification operation can be eliminated, that is, the influence on the fingerprint identification result from the voltage on the data line and sensing line can be eliminated.
