Panel operating apparatus

A panel operating apparatus for changing a state of a display device electrically connected to a circuit board located below a panel having an opening, comprising:

• a tact member arranged on the circuit board in a region of the opening in the panel;
• a thin film covering the opening and at least a portion of a surface of the panel;
• and
• a resilient member arranged in the region of the opening, the resilient member electrically connected to a circuit pattern of the circuit board and being separated from the thin film and the tact member, the resilient member configured to be selectively brought into contact with the panel or the tact member depending on a degree of pressure applied to the thin film,
• wherein the panel operating apparatus is to change a state of a display device electrically connected to the circuit board when the resilient member contacts the panel or the tact member.

An apparatus, comprising:

• a circuit board;
• a tact member disposed on the circuit board;
• a resilient member electrically connected to the circuit board and spaced apart from the tact member;
• a contact member configured to be spaced apart from the resilient member at a first position, to contact the resilient member without the resilient member contacting the tact member in response to a first touch event, and to contact the resilient member with the resilient member contacting the tact member in response to a second touch event.
