  • Patent number: 10739900
    Abstract: A touch display panel includes touch detection electrodes and fingerprint recognition electrodes that share a common electrode layer. The pixel electrodes function as a drive pixel layer to induce capacitive coupling with respect to the fingerprint recognition electrodes, based on which operations of displaying, touch detection, and fingerprint recognition are carried out in a time sharing manner. The touch display panel requires no integration of separately made fingerprint recognition device and a touch display panel, and fingerprint detection can be realized with an existing layered structure of the touch display panel to thereby effectively save the manufacturing cost of the touch display device and achieve an effect of integrating a fingerprint recognition device and a touch display panel. A touch display device that includes the touch display panel is also provided.

  • Publication number: 20170262116
    Abstract: The present invention provides a touch scan drive method. The discrete touch scan is implemented as the touch display panel is in the standby state or the normal display without touch state. Namely, the touch scan pulse signal is merely transmitted to a portion of the emitting electrode in one touch scan, and the signal transmission number is decreased. As the complete touch scan is implemented as the touch display panel is in the touch state, the power consumption of the touch display panel can be reduced under the premise without influencing the normal work and scan precision of the touch display panel.
