Abstract: A high-precision fingerprint sensing method includes providing a fingerprint sensor (10) having a plurality of transistor switches (Q), a plurality of sensing electrodes (SE), a plurality of gate lines (GL), a plurality of data lines (DL), arranging at least one sampling conductor (SC) near the gate lines (GL) to form a coupling capacitance between the sampling conductor (SC) and the gate lines (GL) and to render the sampling conductor (SC) sensing noise on the adjacent gate lines (GL), inverting the noise signal (Vn) obtained from the sampling conductor (SC) into a noise-suppressing signal (Vc) and sending the noise-suppressing signal (Vc) to the fingerprint sensor (10) to suppress noise of the fingerprint sensor (10) and enhance fingerprint sensing accuracy.

Abstract: A hovering and touch sensing apparatus includes a plurality of touch sensing electrodes, a system circuit and a touch control circuit. When an operating object approaches to or touches the touch sensing electrodes for hovering or touch sensing operation, there is no common circuit loop between the system circuit and the touch control circuit to prevent the influence of the system circuit to the touch-sensing circuit. Besides, the touch control circuit sends a capacitance-exciting signal to the operating object through a first specific conductor of the system circuit, thus more effectively send the capacitance-exciting signal to the operating object and enhance the preciseness for sensing the touch sensing signal.

Abstract: A rapid identification method for fingerprint first provides a fingerprint identification apparatus having a fingerprint sensing area and divides the fingerprint sensing area into fingerprint sensing sub-regions. In a registration stage, the method performs fingerprint sensing for the entire fingerprint sensing area to obtain fingerprint image for a whole fingerprint sensing area, fingerprint minutiae and relevant locations for the fingerprint minutiae and then pre-stores those data. In an identification stage, the method performs fingerprint sensing on a part of the fingerprint sensing sub-regions for a user to be identified and detects fingerprint minutiae and relevant locations for the fingerprint minutiae in the part of the fingerprint sensing sub-regions. The method compares the fingerprint minutiae and relevant locations detected in the identification stage with respect to the corresponding fingerprint minutiae and relevant locations in the registration stage in order to determine whether the user can be granted with access right.

Abstract: A self-capacitance organic light emitting touch display apparatus includes a thin film transistor substrate, a common electrode layer, an organic light emitting material layer, at least a touch electrode layer including a plurality of touch sensing electrodes, a display controller, and a touch controller. During touch sensing, the touch controller sequentially or randomly applies a capacitance exciting signal to a selected touch sensing electrode, and senses a touch sensing signal at the selected touch sensing electrode. The touch controller applies a shielding reflection signal to the common electrode layer or a reference point of the display controller.

Abstract: A display device includes a TFT substrate layer, a display material layer, a common electrode layer, a touch electrode layer, a display control circuit and a touch control circuit. The common electrode layer has a common electrode. The touch electrode layer includes plural first touch electrodes and plural second touch electrodes. The display control circuit includes a display power. The touch control circuit includes a touch power independent to the display power. The touch control circuit sequentially or randomly couples a touch stimulation signal to a selected first touch electrode or receives a touch sense signal from a selected second touch electrode. The touch sense signal is driven and coupled to the common electrode layer or a node of the display control circuit for performing a touch detection operation in which there is no current loop between the display control circuit and the touch control circuit.
