    Abstract: A fingerprint identification module and a display device are disclosed. In the fingerprint identification module, a light shading layer above a photosensitive sensing unit includes a first light shading component above a photosensitive diode of the photosensitive sensing unit, and a fixed potential signal line. The first light shading component is electrically connected to a terminal of the photosensitive diode thereunder and connected to the fixed potential signal line. Since the fixed potential signal line is above the photosensitive diode, and the light shading layer is directly used to form the fixed potential signal line, connecting holes that need to occupy some space can be omitted, and the area occupied by the photosensitive diode can be maximized, thus the light current generated by the photosensitive diode during fingerprint detection can be increased so as to enhance fingerprint detection accuracy.

  • Patent number: 10216323
    Abstract: A touch substrate, a display device and a driving method thereof, touch pressure driving electrodes and touch pressure sensing electrodes provided between the layer where the touch detecting electrodes is located and the substrate carrier are added within the touch substrate, and the touch pressure sensing electrodes and the touch pressure driving electrodes constitute a mutual-capacitance structure. When the touch substrate is pressed, the distance between the touch substrate and the underlying metal layer becomes small, causing that capacitance value of the mutual-capacitance structure becomes small. During the time period for detecting pressure, through applying the touch driving signal to the touch pressure driving electrodes to detect the change of signal amount of the touch pressure sensing electrodes caused by the pressure on the touch position, the change of the capacitance value of the mutual-capacitance structure can be determined to achieve the function of pressure sensing.
