Display device, display panel, fingerprint-sensing method, and circuit for sensing fingerprint

The invention relates to a display device 100, a display panel 110, a fingerprint-sensing method, and a circuit for sensing a fingerprint. The display panel comprises a plurality of data lines and gate lines, and a subset of these lines (FPSA, Figure 2) is used to sense a fingerprint. A signal may be transmitted from a data line electrically connected to a pixel electrode (PXL, Figure 3A) through a switching transistor (SWT) and may detect fingerprint information after a driving voltage is applied to the pixel electrode. The device can thus detect a fingerprint without the need for a separate fingerprint sensor outside a display panel, thus simplifying manufacturing. A signal having a turn-on voltage may be used to start a fingerprint-sensing mode, and there may be a charging period preceding a sensing period (Figure 29). Some regions of the display panel could continue showing an image during the fingerprint sensing mode.
