Abstract
A touch sensor includes a sensing cell part having a plurality of sensing cells, a wiring part having a plurality of wires for transmitting a sensing signal of the sensing cell part, and a pad electrode part having a plurality of pad electrodes for transmitting the sensing signal received from the wiring part to an flexible printed circuits board (FPCB), and is coupled to a rear glass of a portable terminal.
Claims16
A touch sensor comprising:
- a sensing cell part having a general touch area and a dummy area located in a device area including a camera within the general touch area, wherein the dummy area is formed of a same material as the general touch area;
- a wiring part having a plurality of wires for transmitting a sensing signal of the sensing cell part;
- and
- a pad electrode part having a plurality of pad electrodes for transmitting the sensing signal received from the wiring part to an FPCB (flexible printed circuit board),
- wherein the touch sensor is coupled to a rear glass of a portable terminal and the rear glass is a rear-most layer of the portable terminal with no element beneath.
2 more elements
A portable terminal comprising:
- a rear glass that is a rear-most layer of the portable terminal with no element beneath;
- a decorative film layer coupled to the rear glass;
- a touch sensor coupled to the decorative film layer and including a sensing cell part having a general touch area and a dummy area located in a device area including a camera within the general touch area, wherein the dummy area is formed of the same material as the general touch area, a wiring part having a plurality of wires for transmitting a sensing signal of the sensing cell part, and a pad electrode part having a plurality of pad electrodes for transmitting the sensing signal received from the wiring part to an FPCB (flexible printed circuit board);
- the FPCB coupled to the pad electrode part of the touch sensor;
- and
- a connection part having one side connected to the FPCB and the other side penetrating or bypassing a rear case of the portable terminal to connect to a PCB (printed circuit board) of the portable terminal.
