Abstract

An erroneous operation is prevented in a display device detecting a touch operation for a display face and a part other than the display face. A display device (1) of the present invention includes: an operation acquiring unit (51) that acquires detection signals transmitted from detection electrodes arranged on a touch panel (14); a use form determining unit (55) that determines a holding form based on a touch position of the touch operation for an end face of the display device; and an insensitive area setting unit (58) that sets an insensitive area on the operation detecting member after the holding form is determined. The operation acquiring unit does not acquire detection signals transmitted from the detection electrodes included in the set insensitive area among the detection electrodes.

Claims

1. :

A display device comprising;

a display member;

an operation detecting member that is superimposed on the display member;

a casing in which the display member and the operation detecting member are stored;

a plurality of detection electrodes being arranged in the operation detecting member, the plurality of detection electrodes detecting a touch operation for a display area of the display member, and some of the plurality of detection electrodes also detecting a touch operation for an end face of the casing other than the display area,

an operation acquiring unit that acquires detection signals transmitted from the detection electrodes;

a use form determining unit that determines a holding form based on a touch position of the touch operation for the end face that is received as the operation acquiring unit acquires the detection signals; and

an insensitive area setting unit that sets an area including the touch position as an insensitive area not receiving the touch operation after the holding form is determined by the use form determining unit,

the operation acquiring unit not acquiring detection signals transmitted from the detection electrodes included in the insensitive area set by the insensitive area setting unit among the plurality of the detection electrodes.

2. :

The display device according to claim 1, wherein the insensitive area setting unit releases the setting of the insensitive area in a case where an event satisfying a predetermined end condition occurs in the display device, the predetermined end condition including at least one of a time when the holding form determined by the use form determining unit is changed, a time when a predetermined time elapses after the insensitive area is set, and a time when switching between screens displayed on the display member is executed.

3. :

The display device according to claim 1, wherein the insensitive area setting unit specifies an insensitive area of the operation detecting member based on the touch position of the touch operation for the end face.

4. :

The display device according to claim 3, wherein the insensitive area setting unit specifies a half circle area having a radius of a predetermined distance and having the touch position of the touch operation for the end face as its center as the insensitive area.

5. :

The display device according to claim 1, further comprising a storage member that stores insensitive area information representing a position of the insensitive area, wherein, while the insensitive area is set to be valid by the insensitive area setting unit, the operation acquiring unit does not acquire detection signals from the detection electrodes included in the insensitive area represented by the insensitive area information stored in the storage member.

6. :

The display device according to claim 5, wherein the insensitive area information represents band-shaped areas each having a predetermined width at left and right ends of the operation detecting member as the insensitive areas.

7. :

The display device according to claim 1, wherein the insensitive area setting unit specifies an insensitive area of the operation detecting member based on the holding form determined by the use form determining unit.

8. :

The display device according to claim 7, wherein the insensitive area setting unit specifies the insensitive area disposed at the left end of the operation detecting member to be wider than the insensitive area disposed at the right end in a case where the determined holding form is left-hand holding and specifies the insensitive area disposed at the right end of the operation detecting member to be wider than the insensitive area disposed at the left end in a case where the determined holding form is right-hand holding.

9. :

The display device according to claim 1, further comprising a process executing unit that executes a predetermined process and generates a screen including an object that can be operated by a touch operation as a result of the execution, wherein the insensitive area setting unit excludes an area in which the object is displayed from the insensitive area.

10. :

A touch-operation processing method executed by a display device including;

a display member;

an operation detecting member that is superimposed on the display member; and

a casing in which the display member and the operation detecting member are stored, a plurality of detection electrodes being arranged in the operation detecting member, the plurality of detection electrodes detecting a touch operation for a display area of the display member, and some of the plurality of detection electrodes also detecting a touch operation for an end face of the casing other than the display area, the touch-operation processing method comprising;

acquiring detection signals transmitted from the detection electrodes;

determining a holding form based on a touch position of the touch operation for the end face that is received as the detection signals are acquired in the acquiring of detection signals;

setting an area including the touch position as an insensitive area not receiving the touch operation after the holding form is determined in the determining of a holding form; and

not acquiring detection signals transmitted from the detection electrodes included in the insensitive area set in the setting of an area among the plurality of the detection electrodes.
