  • Patent number: 11112923
    Abstract: A touch screen, a manufacturing method thereof, and a display device. The touch screen includes: a plurality of mutually independent touch detection regions. Each touch detection region includes a plurality of strip transparent electrodes arranged along a first direction and extending along a second direction, and a plurality of mesh electrodes arranged along the second direction and extending along the first direction. The strip transparent electrodes and the mesh electrodes are insulated from each other, and the second direction is intersected with the first direction. Strip ground electrodes extending along the second direction exist between every two adjacent touch detection regions arranged along the first direction, and the strip ground electrodes and the strip transparent electrodes are disposed on the same layer.

  • Publication number: 20210034164
    Abstract: An input device and an electronic apparatus are provided. The input device includes an input region and a signal processing circuit. The input region includes a first press sensing optical fiber, a second press sensing optical fiber and a key region including a press layer. The first press sensing optical fiber is on a side of the press layer opposite to a user operation side and extends in a first direction. The second press sensing optical fiber is on a side of the first press sensing optical fiber distal to the press layer and extends in a second direction intersecting the first direction. The signal processing circuit is configured to transmit input optical signals to/receive output optical signals from the first and second press sensing optical fibers, and determine press information of the key region according to the output optical signals.
