Abstract: A display device with a force sensing device is provided. The display device with the force sensing device includes a display layer and a non-display layer. The display layer is configured to display an image. The non-display layer is disposed below the display layer. The non-display layer includes a first signal transmission layer and a first signal transmission layer. The deformable layer is disposed on a surface of the first signal transmission layer. The force sensing device includes the deformable layer, the first signal transmission layer and a second signal transmission layer. The second signal transmission layer is disposed above the first signal transmission layer. One of the first signal transmission layer and the second signal transmission layer receives a driving signal and the other of the first signal transmission layer and the second signal transmission layer receives a sensing signal.

Abstract: A touch integrated display device includes a substrate, at one metal layer, a touch sensor and trace layer, and a shielding layer. The substrate includes an active area and a fan out area neighbouring to the active area. The metal layer is disposed over the substrate in the active area, extended to the fan out area and includes a plurality of source lines and a plurality of gate lines. The touch sensor and trace layer is disposed over the metal layer in the active area and extended to the fan out area. The shielding layer is at least disposed at an overlap region of the fan out area where the metal layer and the touch sensor and trace layer are overlapped from a top view to shield electromagnetic interference between the metal layer and the touch sensor and trace layer.

Abstract: An electronic device controlling a touch panel and performing a proximity sensing method is provided. The electronic device includes a touch controller. The touch controller is configured to group a plurality of touch sensors into a sensing group of one or more touch sensors and a non-sensing group of one or more touch sensors, control the sensing group to perform a proximity or hover sensing operation during a first sensing period and not control the non-sensing group to perform the proximity or hover sensing operation during the first sensing period, set one or more first touch sensors of the non-sensing group to a floating state during the first sensing period, and set one or more second touch sensors of the non-sensing group to a simultaneously-driven state during the first sensing period.
