    Abstract: According to an aspect, a detection device includes: a plurality of first sensor electrodes disposed side by side in a first direction and a second direction intersecting the first direction; and a plurality of second sensor electrodes disposed side by side in the first direction and the second direction. One of the second sensor electrodes overlaps a plurality of first sensor electrodes out of the first sensor electrodes in planar view. Each of the second sensor electrodes has a plurality of electric-field transmission regions. One of the electric-field transmission regions overlaps a corresponding one of the first sensor electrodes in planar view and does not straddle two first sensor electrodes in planar view.

    Abstract: According to an aspect, a detection device includes: at least one substrate; a plurality of first electrodes extending in a first direction of the substrate and arrayed in a second direction intersecting the first direction; and a plurality of second electrodes arrayed in at least the first direction in a layer different from a layer of the first electrodes. Each of the second electrodes partially overlaps with the first electrodes in planar view and has an electric-field transmission region, in which an electric field can pass through each of the second electrodes in a direction perpendicular to the substrate. The electric-field transmission region in each of the second electrodes overlaps with one of the first electrodes in planar view.

    Abstract: According to an aspect, a display device with a touch detection function includes a touch detection electrode, a first electrode, a second electrode, a touch detection controller detecting contact with or proximity to an input surface by a detection target object, and a force detection controller calculating a force detection value. The force detection controller corrects the force detection value based on a first capacitance value between the first electrode and the touch detection electrode while the detection target object is neither in contact with nor in proximity to the input surface and a second capacitance value between the first electrode and the touch detection electrode at a position at which the detection target object is neither in contact with nor in proximity to the input surface while the detection target object applies the force to the input surface.

    Abstract: A detection device and a display device include first electrodes, second electrodes, a detector, and a coupling circuit. The first electrodes are disposed side by side in a first direction and a second direction intersecting the first direction. The second electrodes are disposed on the side facing the first electrodes and extend in the second direction. The detector receives a first detection signal output from the second electrodes based on changes in capacitance between the first electrodes and the second electrodes or a second detection signal output from the first electrodes based on changes in capacitance in the first electrodes.

    Abstract: A light sensing apparatus includes a pixel array including Thin Film Transistors (TFTs) and an interface integrated circuit including silicon transistors. The pixel array includes a plurality of pixel circuits. Each of the plurality of pixel circuits includes a light sensitive device and a detection TFT connected to the light sensitive device. The pixel array may also include a plurality of correlated double sampling (CDS) circuits each including a current source configured to provide current that biases a detection TFT in one of the pixel circuits to be configured as a source-follower. The interface integrated circuit includes at least one receiver circuit configured to receive an output of at least one of the CDS circuits. The CDS circuits may also include a bypass TFT, and the interface integrated circuit may also include a current source that provides current that biases a detection TFT in one of the pixel circuits to be configured as a source-follower when the bypass TFT is active.
