Portable terminal
View Patent ↗A portable terminal has a body including a transparent window integrally formed therein, a display disposed beneath the body and visible through the transparent window, and a touch screen located between the display and the body, the touch screen permitting signal input in a capacitive manner.
1. A portable terminal, comprising:
a housing having a transparent window integrally formed therein, the housing including an opaque film located on a lower surface thereof, the opaque film having an open portion to define the transparent window;
a display disposed at the housing, the display displaying information through the transparent window; and
a touch pad disposed between the housing and the display, the touch pad permitting signal input in a capacitive manner, the touch pad having one end electrically connected to at least one of the display and a main circuitry supporting substrate via a flexible printed circuit (FPC), wherein:
the touch pad includes:
a touch sensing-unit disposed at an inner surface of the transparent window and touchable by a user's body via the transparent window; and
a signal-transferring unit disposed at an edge of the touch-sensing unit to transfer a signal corresponding to a coordinate value read by the touch-sensing unit; and
the FPC includes a control circuit mounted thereon, the control circuit being configured to convert the signal generated by the signal transferring unit into the coordinate value and to transfer the coordinate value to a controller of the main circuitry supporting substrate.
2. The portable terminal of claim 1 , wherein the housing is formed by a double injection molding.
3. The portable terminal of claim 1 , wherein the signal-transferring unit disposed at the edge of the touch pad is transparent.
4. The portable terminal of claim 1 , wherein a gap maintaining pad is interposed between an edge of the touch pad and an edge of the display to maintain a gap between the touch pad and the display.
5. A portable terminal, comprising:
a housing having a transparent window integrally formed therein, the housing including an opaque film located on a lower surface thereof, the opaque film having an open portion to define the transparent window;
a display disposed at the housing, the display displaying information through the transparent window; and
a touch pad disposed between the housing and the display, the touch pad permitting signal input in a capacitive manner, the touch pad having one end electrically connected to at least one of the display and a main circuitry supporting substrate via a flexible printed circuit (FPC),
wherein the FPC includes a control circuit mounted thereon, the control circuit being configured to convert a signal generated by the touch pad into a coordinate value and to transfer the coordinate value to a controller of the main circuitry supporting substrate.
