In some cases, it may be possible to configure certain functions to be supported in the idle screen mode.

As described above, the present invention is configured such that a specific function related to various application programs is executed by a multi-touch operation in which a touch operation and a tapping operation are performed in parallel, and based on the touch operation region T, Depending on where it is located, different specific functions are configured to run.

First, a touch manipulation of the touch panel 100 is detected. The touch manipulation of the touch panel 100 may be sensed by a signal generated when a user's body or an input tool (for example, a stylus pen) contacts the touch panel 100.

While the touch manipulation signal according to the touch manipulation of the touch panel 100 is input, a separate function is not executed, and the touch manipulation state is a kind of standby state for quickly executing a specific function according to the tapping manipulation performed after the touch manipulation. It can be understood as.

Next, the tapping manipulation of the other side of the touch panel 100 is sensed while the touch manipulation is continuously maintained. The tapping manipulation may be sensed by a signal generated when the user's body or the input tool contacts the touch panel 100 in the same or similar manner as the above-described touch manipulation.

For reference, in the present invention, the touch operation of the touch panel 100 is continuously maintained after the user's body or the input tool is in contact with the touch panel 100 and is not separated from the touch panel 100. May be maintained and correspond to the stopping or moving (a kind of drag method) of the body or the input tool. In addition, a tapping operation of the touch panel 100 may be understood as a tapping at a point where a body or an input tool is in contact with the touch panel 100 in an instant (a kind of click method) and is not a motion or gesture unlike a touch operation. Can be. In other words, as shown in FIG. 2, the touch signal by the touch operation may be understood as a continuous contact signal, and the tapping signal by the tapping operation may be understood as a contact signal that is relatively short.

Hereinafter, a touch operation and a tapping operation of the touch panel 100 will be described with an example in which the user's hand is implemented. That is, the user touches one side of the touch panel 100 using one finger (for example, a thumb), and the other finger (for example, the index finger while the touch operation is continuously maintained). The other side of the touch panel 100 can be lightly tapped using). In some cases, a user may implement a touch manipulation and a tapping manipulation using both hands, or alternatively, a touch manipulation and a tapping manipulation may be implemented using a body and an input tool.

Next, the position of the tapping manipulation portion TP is determined based on the touch manipulation portion T. That is, in this step, it is determined at which point the tapping operation is performed with respect to the touch manipulation area T based on the touch manipulation area T.

Hereinafter, the area of the touch panel 100 is divided into an upper area A, a lower area B, a left area D, and a right area C based on the touch manipulation area T. In the step of determining the position of the tapping manipulation portion TP on the basis of (T), the tapping manipulation portion TP is formed in the upper region A, the lower region B, the left region D, and the right region C. Will be described by way of example.

For example, as shown in FIG. 3, in the region of the touch panel 100, the upper region A and the lower region B may be provided on the upper and lower portions based on a horizontal center line passing through the touch manipulation portion T. The left area D and the right area C may be provided on the left and right sides with respect to the vertical center line passing through the touch manipulation part T. In addition, the boundary between the upper region (A) and the lower region (B) and the left region (D) and the right region (C) may be provided to be inclined at an angle of 10 to 50 ° relative to the vertical center line. That is, the boundary angle θ between the upper region A and the lower region B and the left region D and the right region C is less than 10 degrees or less than 50 degrees with respect to the vertical center line. If large, the left region D and the right region C may be asymmetrically too small or large compared to the upper region A and the lower region B. For example, considering the range of motion of the finger around the joint, the boundary between the upper region A and the lower region B and the left region D and the right region C is 10 to 10 with respect to the vertical center line. Preferably provided at an angle of 50 °.

As described above, the area of the touch panel 100 may be divided into an upper area A, a lower area B, a left area D, and a right area C based on the touch manipulation area T. In the state where the touch operation is continuously maintained, it is possible to determine whether the tapping signal according to the tapping operation is among the upper region A, the lower region B, the left region D, and the right region C.

Thereafter, different specific functions related to the activated application are executed according to the determined result, that is, according to a result of determining where the position of the tapping manipulation portion TP is based on the touch manipulation portion T. do.

For reference, the specific function related to the application in the present invention may be changed according to the type and characteristics of the application to be activated. For example, in the photo (image) management application mode may be a specific function related to the rotation, enlargement, reduction and editing of the photo. In the digital music reproduction application mode, the digital music reproduction application mode may be a specific function related to play, stop, and skip of music. In the phone application mode, it may be a specific function related to adjusting the call volume, the phone book, recording the call, taking notes, and the like. In the digital camera application mode, it may be a specific function related to shooting setting, environment setting, flash, and zoom. In addition, the specific function may be a specific function related to saving, deleting, undoing (going back), redoing (going forward), sending, cutting, managing, searching, and the like.

Hereinafter, referring to FIGS. 3 to 6, a step of executing a specific function according to the position of the tapping manipulation portion TP with respect to the touch manipulation portion T will be described in more detail.

For example, if a tapping operation is performed in the upper region A while the touch operation is continuously maintained as shown in FIG. 3, a specific function related to image enlargement may be executed. In contrast, as shown in FIG. 4, the touch operation is continuously maintained. If a tapping operation is performed in the lower region B while the operation is performed, a specific function related to image reduction may be executed. In addition, when the tapping operation is performed in the right region C while the touch operation is continuously maintained as shown in FIG. 5, a specific function related to the clockwise rotation of the image may be executed. In contrast, as shown in FIG. 6, the touch operation is continuously performed. If the tapping operation is performed in the left area D while being maintained, the specific function related to the counterclockwise rotation of the image can be executed.

In the above-described and illustrated embodiments of the present invention, the area of the touch panel 100 is based on the touch manipulation area T, and includes the upper area A, the lower area B, the left area D, and the right area C. Although described as an example divided into four areas including, in some cases, the area of the touch panel may be divided into a smaller number or a larger number than the above four areas based on the touch manipulation area. In addition, the boundaries of each region can be freely changed. For example, according to another embodiment of the present invention, the area of the touch panel may be divided into only two areas of the upper area and the lower area (or the left area and the right area) on the basis of the touch manipulation area, and tapping according to a tapping operation When the signal is input in the upper region, a function related to magnification may be executed, and when the tapping signal according to the tapping operation is input in the lower region, a function related to reduction may be executed.

Meanwhile, according to the present invention, the degree of execution of a specific function may be configured to vary according to the distance between the above-described touch manipulation part T and the tapping manipulation part TP. For example, while the touch manipulation is continuously maintained as shown in FIG. 7, the distance between the touch manipulation portion T and the tapping manipulation portion TP is “L1” under the condition that the tapping manipulation is performed in the upper region A. FIG. In this case, the magnification (or speed) of the image may be performed at a 2x magnification. In the case where the distance between the touch manipulation area T and the tapping manipulation area TP is "L1" which is larger than the above-mentioned "L1", the enlargement of the image Magnification (or speed) can be performed at four magnifications. In the embodiment of the present invention, an example in which the tapping operation is configured to vary the degree of execution of a specific function under the condition in which the tapping operation is performed in the upper area A is described. The degree of execution of a specific function can be varied even under the condition in any one of the areas C. FIG.

In addition, according to the present invention, the degree of execution of a specific function may be varied or different specific functions may be executed according to the number of tapping operations corresponding to a plurality of repeated tapping operations while the touch operations are continuously maintained. For example, as shown in FIG. 8, when two tapping operations are repeatedly performed on the same portion of the other side of the touch panel 100 while the touch operations are continuously maintained, another specific function related to the storage of the image of the current state is performed. It can be configured to run.

Although FIG. 8 illustrates an example in which another specific function related to storage is executed by a repetitive tapping operation, in some cases, the degree of execution of a specific function as in the above-described embodiment by a repetitive tapping operation (for example, For example, the magnification may be varied. In addition, the number of repetitions of the tapping operation may be variously changed to three or more times according to the required conditions and design specifications, and depending on the number of repetitions of the tapping operation, the degree of execution of a specific function may vary or different specific functions may be used. It can be configured to run.

Further, according to the present invention, the degree of execution of a specific function is variable or different from each other depending on the number of simultaneous tapping manipulation sites TP in response to the simultaneous tapping manipulation at at least two points spaced from each other while the touch manipulation is continuously maintained. The function can be configured to run. For example, as shown in FIG. 9, when the simultaneous tapping operation is performed at two spaced points of the touch panel 100 while the touch operation is continuously performed, the function of returning to the previous stage of the image of the current state (reviving or going back) ) Can be configured to execute specific functions.

Although FIG. 9 illustrates an example configured to return to a state before a specific function is executed by a simultaneous tapping operation at at least two points spaced from each other, in some cases, a simultaneous tapping operation at at least two points spaced from each other may be used. The image may be initialized to an initial state, or may be configured such that the degree of execution of a specific function (for example, an enlargement magnification) varies. In addition, the number of simultaneous tapping manipulation sites TP may be variously changed to 3 or more according to required conditions and design specifications. Depending on the number of simultaneous tapping manipulation sites TP, the degree of execution of a specific function may vary. It can be configured to execute different or different specific functions.

In addition, according to the present invention, when the touch operation is released, it may be configured to return to the state before the specific function is executed or to initialize the initial state. For example, as shown in FIG. 10, when the touch manipulation is released, the image may be initialized to an initial state. Of course, in some cases, it may be configured to return to the state just before the execution of a specific function according to the release of the touch operation.

In addition, according to the present invention, if another touch manipulation T2 is detected on the other side of the touch panel 100 while the touch manipulation T1 is continuously maintained, the execution degree of the specific function may be varied or different specific functions may be executed. Can be configured. For example, as shown in FIG. 11, when another touch operation T2 is made in the upper area A while the touch operation T1 is continuously maintained, enlargement of the image while another touch operation T2 is maintained. Can be made continuously at a predetermined magnification and speed. In the embodiment of the present invention has been described with an example configured to vary the degree of execution of a specific function in the condition that the other touch operation is performed in the upper region (A), the other touch operation is the lower region (B), the left region (D) And the degree of execution of the specific function may be varied even under the condition in any one of the right region C. FIG.

Meanwhile, in FIG. 11, for example, when another touch manipulation is sensed on the other side of the touch panel 100 while the touch manipulation is continuously maintained, an execution degree of a specific function is changed or different specific functions are executed. Although described, in some cases, when another touch manipulation is sensed on the other side of the touch panel 100 while the touch manipulation is continuously maintained, the touch signal according to the other touch manipulation is one point of the touch panel 100. Is inputted at or at least two points spaced apart from each other of the touch panel 100, and the degree of execution of a specific function is varied or different specific functions are executed according to the determined result.

Meanwhile, in the above description, a specific function is simply configured to be executed when a tapping operation is detected while the touch operation is continuously maintained, but in some cases, execution related to a specific function while the specific function is executed by the touch and tapping operation. The display icon 200 corresponding to the state may be temporarily activated. For example, while an image mode is executing a specific function related to zooming and rotating, the display icon related to the zooming and rotating function is temporarily activated so that the user can recognize that the specific function related to zooming and rotating is normally executed. In addition, a display icon related to the save and restore function may be temporarily activated. For reference, that the display icon 200 is temporarily activated, the display icon 200 is activated and displayed only while a specific function is executed, and after the execution of the specific function is completed, the display icon 200 is automatically displayed. It can be understood to be deactivated to disappear.

On the other hand, the driving algorithm related to the operation method of the above-described and illustrated touch panel may be applied to the driving chip (driving chip). The driving chip may be mounted on a PCB or FPCB of a personal mobile terminal to output signals required for driving and controlling the touch panel.

That is, in the personal mobile terminal having the touch panel according to the present invention, the driving chip for driving the touch panel 300 is touched while the touch manipulation of the touch panel 100 is detected and the touch manipulation is continuously maintained. 100) If a tapping manipulation of the other side is detected, the position of the tapping manipulation site is determined based on the touch manipulation area, and according to the determined result, a function for executing a specific function related to the activated application program of the personal mobile terminal is determined.

For example, when the driving chip 300 determines the position of the tapping manipulation portion based on the touch manipulation portion, the tapping manipulation portion is an upper region, a lower region, and the left side of the touch manipulation region in the region of the touch panel 100. It can be configured to determine which of the region and the right region, and output a signal for executing different specific functions according to the determined result.

In addition, the driving chip 300 may include a distance between the touch manipulation portion and the tapping manipulation portion, the number of tapping operations corresponding to a plurality of repeated tapping manipulations, and simultaneous tapping manipulations at at least two spaced apart positions of the touch panel 100. According to the number of simultaneous tapping manipulation sites corresponding to and other touch manipulations on the other side of the touch panel 100 while the touch manipulations are continuously maintained, corresponding "independent signals" (distance signal, tapping manipulation count signal Outputting each of the simultaneous tapping manipulation number signals and other touch manipulation signals, or independently of a signal for executing the specific function (position signal of the tapping manipulation portion with respect to the touch manipulation portion, hereinafter referred to as "position signal"). It is possible to output a control signal processed with each of the signals. Accordingly, the " signal for executing a specific function " and " independent signal " or the control signal can be used to vary the degree of execution of a particular function or to execute different specific functions. In addition, when the touch manipulation is released, the driving chip 300 may be configured to output a control signal for returning to a state before the specific function is executed or for initializing the initial state.

That is, the driving chip 300 may independently output a "distance signal" according to the distance between the touch manipulation portion and the tapping manipulation portion, and the main driving chip (not shown) of the terminal may be a "position signal" and The "distance signal" can be used to output a signal for varying the degree of execution of a particular function (see FIG. 7).

In addition, the driving chip 300 independently outputs a "tap operation number signal" according to the number of tap operations in response to the tapping operation repeated a plurality of times, or the "tap operation number signal" is processed together with the "position signal". Outputting the "control signal", the main driving chip (not shown) of the terminal using the "position signal" and the "tap operation number signal" or the "control signal" the degree of execution of the specific function Can output a signal for varying or executing different specific functions (see FIG. 8).

In addition, the driving chip 300 may provide a "simultaneous tapping manipulation number signal" according to the number of simultaneous tapping manipulation sites in response to the simultaneous tapping manipulation at at least two spaced points of the touch panel while the touch manipulation is continuously maintained. Independent output or a "control signal" in which the "simultaneous tapping operation number signal" is processed together with the "position signal" can be output, and the main driving chip (not shown) of the terminal is a "position signal" and "simultaneous tapping operation" The number signal may be used, or the control signal may be used to vary a degree of execution of the specific function or to output a signal for executing different specific functions. (See FIG. 9).

In addition, the driving chip 300 independently outputs "another touch manipulation signal" as another touch manipulation is sensed on the other side of the touch panel while the touch manipulation is continuously maintained, or "different with position signal". The touch control signal may be processed to output a "control signal", and the main driving chip (not shown) of the terminal may use the "position signal" and the "other touch manipulation signal" or the "control signal" The degree of execution of the specific function may be varied or a signal for executing different specific functions may be output (see FIG. 11).

For reference, the control signal in the above description may be understood as one independent signal including information of two different signals. For example, the " position signal " and the " count signal " may be processed and output as one independent " position count signal " including both information (position + number).
