For example, when the electronic device is operating in a phone call mode, the display unit 151 will provide a User Interface (UI) or a Graphic User Interface (GUI), which includes information associated with the call. As another example, if the electronic device is in a video call mode or a capturing mode, the display unit 151 may additionally or alternatively display images captured and/or received, UI, or GUI.
The display unit 151 may be implemented using, for example, at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-Liquid Crystal Display (TFT-LCD), an Organic Light-Emitting Diode (OLED), a flexible display, a three-dimensional (3D) display, an e-ink display or the like.
Some of such displays 151 may be implemented as a transparent type or an optical transparent type through which the exterior is visible, which is referred to as ‘transparent display’. A representative example of the transparent display may include a Transparent OLED (TOLED), and the like. The rear surface of the display unit 151 may also be implemented to be optically transparent. Under this configuration, a user can view an object positioned at a rear side of a terminal body through a region occupied by the display unit 151 of the terminal body.
The display unit 151 may be implemented in two or more in number according to a configured aspect of the electronic device 100. For instance, a plurality of the displays 151 may be arranged on one surface to be spaced apart from or integrated with each other, or may be arranged on different surfaces.
Here, if the display unit 151 and a touch sensitive sensor (referred to as a touch sensor) have a layered structure therebetween, the structure may be referred to as a touch screen. The display unit 151 may be used as an input device rather than an output device. The touch sensor may be implemented as a touch film, a touch sheet, a touchpad, and the like.
The touch sensor may be configured to convert changes of a pressure applied to a specific part of the display unit 151, or a capacitance occurring from a specific part of the display unit 151, into electric input signals. Also, the touch sensor may be configured to sense not only a touched position and a touched area, but also touch pressure.
When touch inputs are sensed by the touch sensors, corresponding signals are transmitted to a touch controller. The touch controller processes the received signals, and then transmits corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched.

When the touch screen is implemented as a capacitance type, proximity of a pointer to the touch screen is sensed by changes of an electromagnetic field. In this case, the touch screen (touch sensor) may be categorized into a proximity sensor.
Hereinafter, for the sake of brief explanation, a status that the pointer is positioned to be proximate onto the touch screen without contact will be referred to as ‘proximity touch’, whereas a status that the pointer substantially comes in contact with the touch screen will be referred to as ‘contact touch’. For the position corresponding to the proximity touch of the pointer on the touch screen, such position corresponds to a position where the pointer faces perpendicular to the touch screen upon the proximity touch of the pointer.
The proximity sensor 141 senses proximity touch, and proximity touch patterns (e.g., distance, direction, speed, time, position, moving status, etc.). Information relating to the sensed proximity touch and the sensed proximity touch patterns may be output onto the touch screen.

The alarm unit 153 may output not only video or audio signals, but also other types of signals such as signals notifying occurrence of events in a vibration manner. Since the video or audio signals can be output through the display unit 151 or the audio output module 152, the display unit 151 and the audio output module 152 may be categorized into a part of the alarm unit 153.
The haptic module 154 generates various tactile effects which a user can feel. A representative example of the tactile effects generated by the haptic module 154 includes vibration. Vibration generated by the haptic module 154 may have a controllable intensity, a controllable pattern, and so on. For instance, different vibration may be output in a synthesized manner or in a sequential manner.

Also, the information input on the electronic note may be stored (saved) in the memory 160 or sent to the exterior depending on a user selection.
Hereinafter, description will be given in more detail of a method of utilizing the electronic note function based on reception of color information from the touch tool 300 shown in
As shown in
As shown at the step S310, when the color information is received, the controller 180 of the electronic device 100 may output an image object, which is displayed with a color corresponding to the received color information, on the display unit 151 (S320, see
As shown in
Next, when a touch input is applied by a user's finger or the touch tool onto the image object which is output on the display unit 151 with the color corresponding to the received color information, the controller 180 may activate the electronic note function (S330).
In the meantime, the case where the electronic note function is activated based on the touch input applied by the touch tool may be limited to a case where the user applies a touch input onto the image object with pressing a specific button (for example, the activation button 320, see
For example, as shown in
Although not shown, the controller 180 may activate the electronic note function while continuously outputting screen information 201 (see
Although not shown, if the user does not want to execute the electronic note function immediately even though he or she has received the color information, the user may keep using the screen information output prior to recognition of the color information by way of touching a region where the image object 210 is not displayed. Here, the image object 210 may not be output on the display unit 151 any more.
In addition, when a touch input onto the image object 210 is not sensed for a predetermined time, the controller 180 may control the display unit 151 not to display the image object 210 thereon any more.
As such, in the electronic device according to the present disclosure, even when the electronic note function is not activated immediately, the color information received from the touch tool 300 may be stored in the memory 160, and the user may input information using the color corresponding to the received color information when executing the electronic note function later.
When information is input on the display unit 151 in response to a touch input applied onto the display unit 151 by the user's finger or the touch tool 300 after activating the electronic note function, the input information may be displayed with the color corresponding to the color information received from the touch tool (S340).
That is, as shown in
As described above, the electronic device according to this specification may provide the method for conveniently activating the electronic note function. Also, the electronic device may output the image object, which is displayed with the color corresponding to the received color information, on the display unit. This may allow the user to confirm in real time whether or not a color which the user desired to recognize has been correctly recognized.
Hereinafter, description will be given in more detail of a method of activating the electronic note function as soon as releasing a lock state of the electronic device when color information is received from an external touch tool in the lock state, with reference to the accompanying drawings.
Here, the lock state indicates a state that the user is restricted from inputting a control command with respect to applications installed in the electronic device. This is to prevent functions and applications of an electronic device, which has a touch screen (or the display unit 151 implemented as the touch screen), from being activated or deactivated due to an input of a control command undesired by the user. Hence, it may be possible in the lock state to restrict a control command from being input by the user via the touch screen (or the display unit 151) and other user input unit 130 within a preset range.
Meanwhile, the user's input of the control command is restricted in the locked state, but functions and applications of the electronic device which were being activated prior to execution of the lock state may be continuously executed.
An unlock (release) state indicates a state that the user's input of the control command with respect to the electronic device is not restricted. Therefore, in the unlock state, the functions and applications of the electronic device may be activated or deactivated according to a control command input by the user via the touch screen (or the display unit 151) or the user input unit 130.
Here, the unlock state may be executed when a user input with respect to the touch screen (or the display unit 151) and other user input unit 130 disposed on the electronic device is not sensed for a preset time. The preset time may change depending on user's settings. Also, the lock state may be executed when the user presses a specific key (for example, a hold key) disposed on the electronic device, which is preset for the lock state.
Accordingly, in the lock state, when color information is received from an external touch tool, the controller 180, as shown in
The controller 180 may activate the electronic note function as soon as converting the lock state into the unlock state. Therefore, an execution screen for the electronic note function may be output on the display unit 151.
As such, the electronic device may output an image object on a lock screen based on recognition of color information from the exterior, and activate an electronic note function as soon as converting a lock state into an unlock state using the displayed image object. Therefore, the user may be able to fast enter the electronic note function in the lock state.
Referring to
Here, “the deactivated state of the display unit 151” indicates a state in which a lighting device (light) disposed within the display unit 151 for lighting it up is in a turn-off state. That is, in the deactivated state of the display unit 151, any information or graphic image may not be displayed on the display unit 151. On the contrary, “an activated state of the display unit 151” indicates a state in which the lighting device (or light) within the display unit 151 is in a turn-on state. Therefore, in this state, information may be output on the display unit 151.
As such, the electronic device according to the present disclosure may automatically convert the display unit from a deactivated state into an activated state in response to reception of color information, such that a user can recognize a color corresponding to the color information received from the exterior immediately on the display unit.

As one example of the method for changing the attribute information, referring to
For example, as shown in
As shown in
As such, the controller 180 may change the attribute information along the moving path of the touch input starting from the image object 210. Also, the guide images 220, 230 associated with the attribute information may be output on the display unit 151 such that the user can identify the attribute information changed according to the motion of the touch input. The controller 180 may also select attribute information corresponding to a point where the touch input is released on the guide image 220, 230.

Meanwhile, the method of changing the attribute information using the image object displayed in the lock state has been illustrated with reference to
As described above, the electronic device may display an image object in response to reception of color information from the exterior, so as to provide a user with information relating to a color recognized by an external touch tool and allow the user to set attribute information using the image object in a convenient manner.
Also, the method of displaying the image object in the lock state and converting the lock state into the unlock state in response to the preset type of touch input with respect to the image object has been illustrated with reference to
First, as one example, referring to
When a touch input is applied onto the image object 210, the controller 180 may activate the electronic note function at the moment of the conversion from the lock state into the unlock state. Also, when a touch input corresponding to a general unlock method, other than the touch input onto the image object 210, is applied, the electronic note function may not be activated. That is, in this case, a home screen page may be output on the display unit 151.
As another example, referring to

As another example, referring to
As another example, referring to
Here, the touch tool may be able to recognize that it has moved between the display unit and the bezel region, and transmit the recognized signal to the controller 180 of the electronic device 100. Therefore, when a motion pattern of the touch tool corresponding to the signal received from the touch tool matches a preset reference, the controller 180 may convert the lock state into the unlock state. Here, the touch tool may determine whether it is currently located on the display unit or on the bezel region based on the image object 210 displayed on the edge region of the display unit.
As described in the examples, the electronic device may convert the lock state into the unlock state in response to various types of touch inputs applied onto the image object, and thereafter fast execute the electronic note function.
The foregoing embodiments have illustrated the method of displaying the color information on the lock screen when the color information is received from the external touch tool in the lock state. Hereinafter, description will be given in more detail of a method of activating the electronic note function when color information is received from the exterior in a state that screen information relating to the electronic device is displayed in an unlock state.
As shown in
As another example, as shown in
Although not shown, when the user does not desire to execute the electronic note function immediately even though the color information is received, the user may keep using the screen information output prior to recognition of the color information by way of touching a region where the image object 210 is not displayed. Here, the image object 210 may not be output on the display unit 151 any more.
In addition, when a touch input applied onto the image object 210 is not sensed for a preset time, the controller 180 may control the display unit 151 not to display the image object 210 thereon any more.
So far, the examples of receiving one color information from the exterior have been illustrated. Hereinafter, description will be given in more detail of a method for utilizing the electronic note function in response to reception of a plurality of color information, with reference to the accompanying drawings.
First, as shown in
In the meantime, the user may recognize a plurality of colors in a manner of recognizing a first color after pressing the activation button 310 disposed on the touch tool 300, releasing the activation button 310, and thereafter pressing the activation button 310 again. Here, a time interval for pressing or releasing the activation button 310 may be preset. The controller 180 may recognize the reception of the plurality of color information only when the plurality of color information are received from the touch tool 300 in a consecutive manner within the preset time interval.
As shown in
Also, the controller 180 may display information using a color, which is selected by a user using a touch tool or a touch input, in addition to the method of displaying information using the color corresponding to the last received color information.
The controller 180, as shown in
The controller 180, as shown in
For example, while information is displayed with a first color in response to a touch input applied using the touch tool 300, when the activation button 310 of the touch tool 300 is selected, the touch tool 300 may transmit a wireless signal to the electronic device 100. The controller 180 may then change a display color from the currently selected color into another color based on the received wireless signal. Therefore, as shown in
Although not shown, the touch tool 300 may also recognize one of colors constructing screen information output on the display unit 151 as well as recognizing a color of an object which is located at the outside of the electronic device. Here, the controller 180 may distinguish a touch input, which is applied onto the display unit 151 by the touch tool 300 to input a control command, from a touch input, which is applied onto the display unit 151 by the touch input 300 to recognize a color output on the display unit 151. For example, when a touch input is applied onto the display unit 151 with the activation button 310 of the touch tool 300 being pressed, the controller 180 may determine it as a touch input for recognizing the color output on the display unit 151, and may not generate a control command corresponding to the touch input. On the contrary, when a touch input is applied onto the display unit 151 without the activation button 310 of the touch tool 300 being pressed, the controller 180 may determine it as a touch input for inputting a control command, and generate a control comment corresponding to the touch input.
In the meantime, in addition to a color table (or color palette) 220 shown in
The application corresponding to the screen information output on the separate output window or the one region of the display unit 151 may be an application, which is being multitasked with the electronic note application, a recently executed application or an application selected by a user.
In response to a user selection, the memo or image (or photo) stored in the memory 160 or the execution screen of the application may be output on a region where the color palette 220 (see
Hereinafter, description will be given in more detail of a method of recognizing pattern information including a plurality of colors using a touch tool, with reference to the accompanying drawings.
As shown in
As described above, the electronic device according to the present disclosure may provide various user interfaces by recognizing patterns other than a monochromic color.
Hereinafter, description will be given in more detail of a method of controlling an electronic note function according to a position of the electronic device by using a proximity sensor or another sensor provided in the electronic device.
For example, as shown in
As such, position information relating to the electronic device may be recognized through location coordinates recognized via the proximity sensor 141, GPS, Wi-Fi or the like. Also, the position information (or situation information) relating to the electronic device may be recognized through a light sensor. When color information is received from the external touch tool 300, the controller 180 may check a state of the electronic device body using the proximity sensor 141. When the electronic device body is in a first state that the user is able to check information displayed on the electronic device, the controller 180 may display an image object corresponding to the color information received on the display unit 151. When the electronic device body is in a second state that the user is unable to check information displayed on the electronic device, the controller 180 may output the image object on the display unit after waiting until the state of the device body is converted into the first state.
This may allow the user to be provided with the received color information at the time point of being able to view the information, and also prevent the electronic device from consuming energy due to unnecessarily displaying information when the user is unable to check the display unit.
Meanwhile, as shown in
Consequently, the electronic device according to the present disclosure may be configured to recognize the situation that the user is able to check information, thereby avoiding the situation that the user is unable to check information.
As described above, in an electronic device and a control method thereof according to one exemplary embodiment of the present disclosure, color information may be received from an external touch tool having a color recognition function via a wireless signal. This may allow the user to utilize an electronic note function using various colors even when those colors are not previously stored in the electronic device.
In addition, in the electronic device and the control method thereof according to the one exemplary embodiment of the present disclosure, an electronic note function may be quickly activated in response to a touch input applied onto an image object corresponding to color information received from an external touch tool.
Further, in accordance with one embodiment of the present disclosure, the method can be implemented as computer-readable codes in a program-recorded medium. The computer-readable medium may include all types of recording devices each storing data readable by a computer system. Examples of such computer-readable media may include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage element and the like. Also, the computer-readable medium may also be implemented as a format of carrier wave (e.g., transmission via an Internet). The computer may include the controller 180 of the electronic device.
The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present disclosure. The present teachings can be readily applied to other types of apparatuses. This description is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art. The features, structures, methods, and other characteristics of the exemplary embodiments described herein may be combined in various ways to obtain additional and/or alternative exemplary embodiments.
As the present features may be embodied in several forms without departing from the characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are therefore intended to be embraced by the appended claims.
