Abstract:
A display device includes a display having an array of pixels separated by inter-pixel gaps in at least one dimension. An electrode having a length direction is formed over the display and extends across at least a portion of the array of pixels. The electrode includes a plurality of electrically connected micro-wires formed in a micro-pattern. The micro-pattern has a first set of parallel micro-wires oriented at a first angle non-orthogonal to the length direction and a second set of parallel micro-wires oriented at a second angle non-orthogonal to the length direction different from the first angle. The micro-wires of the first and second sets intersect to form an array of electrically connected micro-wire intersections. At least every other micro-wire intersection on the micro-wires of the first set is located between the pixels in the inter-pixel gaps.

Each electrode includes a plurality of patterned conductive electrically connected electrode micro-wires. One or more patterned equi-potential electrically conductive dummy micro-wires in the area are located substantially along equi-potential lines between adjacent electrodes and are electrically isolated from the electrode micro-wires so that the area has a substantially uniform optical density. An unpatterned conductive layer is located in the area in electrical contact with the electrode micro-wires and the dummy micro-wires.

A touch-screen device includes a transparent dielectric layer. A plurality of first electrodes is located over the transparent dielectric layer. A plurality of second electrodes is located under the transparent dielectric layer so that the first electrodes overlap the second electrodes to form an array of capacitors. A controller provides electrical signals to the first and second electrodes to energize and measure the baseline capacitance and repeatedly energize and measure the present capacitance of each capacitor. The controller calculates a ratio function between the present capacitance and the corresponding stored baseline capacitance for each capacitor and provides a touch signal when the ratio function exceeds a predetermined threshold value.

Abstract:
An electronic sensing system has a transceiver with input and output pads, an excitation circuit connected to the output pad, and a detection circuit connected to the input pad. An electrically-conductive sensor patch has an electrical state that changes with exposure to a corresponding environmental factor. The detection circuit detects an electrical state of the input electrical-connection pad in response to the excitation signal and the electrical state of the sensor patch. A stack of one or more layers in order is disposed over the sensor patch in the detection region. Each layer is susceptible to a respective environmental factor, so that the sensor patch changes electrical state in response to exposure of the layer stack to the respective environmental factors of the one or more layer(s) in the selected order and subsequent exposure of the sensor patch to the corresponding environmental factor.
