Electronic device and control method therefor
According to an embodiment, a method of controlling an electronic device including a touch screen panel (TSP) at least a part of which is located in a housing may be withdrawn to the outside of the housing comprises: identifying a withdrawal extent of the TSP; selecting a reference line for controlling a power supplying range of a plurality of touch areas among a plurality of lines for dividing a plurality of touch areas of the TSP based on the withdrawal degree; supplying power to touch areas in a first direction in which the TSP is withdrawn based on the reference line and blocking power to touch areas in a second direction opposite to the first direction based on the reference line, among the plurality of touch areas; and restricting touch recognition with respect to a part extending from the reference line in one touch area adjacent to the reference line among the touch areas in the first direction.
1 . A method of controlling an electronic device comprising a touch screen panel (TSP) disposed at least partially in a housing, and at least a portion of which is able to be withdrawn from the housing in an extension direction, the method comprising:
identifying a withdrawal degree of the TSP;
based on the withdrawal degree, selecting a reference line from a plurality of lines that partition a plurality of touch areas of the TSP,
wherein the reference line is a closest line in a reduction direction, opposite to the extension direction, from a boundary line, and
wherein the boundary line separates an inside and outside of the housing from which the TSP is withdrawn;
supplying power to a first touch area in the extension direction based on the reference line and blocking power to a second touch area in the reduction direction based on the reference line; and
restricting touch recognition for touch input to a portion of the first touch area between the boundary line and the reference line.
2 . The method of claim 1 , wherein the restricting the touch recognition comprises:
for the portion extending from the reference line in the touch area, lowering touch recognition sensitivity or based a touch being sensed, ignoring or rejecting the touch.
3 . The method of claim 1 , further comprising:
sensing a change in the withdrawal degree of the TSP; and
in response to sensing the change in the withdrawal degree of the TSP, adjusting the reference line.
4 . The method of claim 1 , further comprising:
sensing a change in the withdrawal degree of the TSP; and
in response to sensing the change in the withdrawal degree of the TSP, adjusting a range of the portion in which touch recognition is restricted.
5 . The method of claim 1 , further comprising:
setting a range of the portion in which touch recognition is restricted as part of a calibration,
wherein the calibration comprises:
receiving a touch input in a touch area in contact with the reference line in the touch area; and
based on the received touch input, adjusting the range of the portion in which touch recognition is restricted.
6 . The method of claim 5 , wherein the calibration comprises:
changing the withdrawal degree of the TSP; and
sensing a position change of a boundary between an inside and an outside of the housing from which the TSP is withdrawn and receiving a touch input in a partial area of a touch area adjacent to a sensed boundary, in response to a change in the withdrawal degree of the TSP.
7 . The method of claim 6 , wherein changing the withdrawal degree of the TSP changes the withdrawal degree of the TSP by a numerical value within an interval in which the plurality of lines are spaced apart from each other.
8 . The method of claim 5 , wherein the calibration further comprises:
displaying visual information on the TSP indicating a position where the touch input is input.
9 . The method of claim 5 , wherein the calibration is performed after the restricting touch recognition.
10 . An electronic device comprising:
a first housing, and a second housing configured to be movable relative to the first housing;
a touch screen panel (TSP) configured to be withdrawn from an outside of the plurality of housings as the second housing moves;
a memory configured to store executable instructions; and
at least one processor, comprising processing circuitry, configured to access the memory and execute the instructions,
wherein at least one processor, individually and/or collectively, is configured to:
select a reference line from among a plurality of lines that partition a plurality of touch areas of the TSP,
wherein the reference line is a closest line in a reduction direction, opposite to the extension direction, from a boundary line, and
wherein the boundary line separates an inside and an outside of the housing from which the TSP is withdrawn;
supply power to a first touch area in the extension direction based on the reference line and blocking power to a second touch area in the reduction direction based on the reference line, among the plurality of touch areas; and
restrict touch recognition for touch input to a portion of the first touch area between the boundary line and the reference line.
11 . The electronic device of claim 10 , wherein at least one processor, individually and/or collectively, is configured to:
for the portion extending from the reference line in the touch area, lower touch recognition sensitivity or based on a touch being sensed, ignore or reject the touch.
12 . The electronic device of claim 10 , wherein at least one processor, individually and/or collectively, is configured to:
in response to a change in the withdrawal degree of the TSP being sensed, adjust a range of the portion in which touch recognition is restricted.
13 . The electronic device of claim 10 , wherein at least one processor, individually and/or collectively, is configured to:
sense a position change of the boundary between the inside and outside of the plurality of housings from which the TSP is withdrawn and receive a touch input in a partial area of a touch area adjacent to a sensed boundary to adjust basic information for setting the range of the portion in which touch recognition is restricted.
