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.

INTEGRATED TOUCH PANEL FOR A TFT DISPLAY

This relates to displays for which the use of dual function capacitive elements does not result in any decreases of the aperture of the display. Thus, touch sensitive displays that have aperture ratios that are no worse than similar non-touch sensing displays can be manufactured. More specifically, this relates to placing touch sensing opaque elements so as to ensure that they are substantially overlapped by display related opaque elements, thus ensuring that the addition of the touch sensing elements does not substantially reduce the aperture ratio. The touch sensing display elements can be, for example, common lines that connect various capacitive elements that are configured to operate collectively as an element of the touch sensing system.

Ito-coated article for use with touch panel display assemblies, and/or method of making the same

Certain example embodiments of this invention relate to techniques for making a coated article including a transparent conductive indium-tin-oxide (ITO) film supported by a heat treated glass substrate. A substantially sub-oxidized ITO or metallic indium-tin (InSn) film is sputter-deposited onto a glass substrate at room temperature.
