2. Description of the Related Art
Portable terminal devices include, for example, Personal Digital Assistants (PDAs), navigation devices, laptop computers, mobile phones, and the like. Portable terminals make use of display devices such as a Liquid Crystal Display (LCD), Organic Light Emitting Diodes (OLEDs), and the like.
A touch screen capable of receiving an input on a display screen thereof is widely used. Various display elements to be applied to next-generation display devices have been developed and are undergoing testing, or are being developed.
Recently, a transparent display device called a Transparent Organic Light Emitting Diode (TOLED) has been developed, and research is being conducted for applying TOLEDs to various devices, such as the dashboard of an automobile, a display of a portable terminal, a virtual reality device having the shape of eyeglasses, and the like.
Typically, a touch screen is used in a transparent display device applied to the portable terminal such as a mobile phone, and a touch screen is applied to both-side surfaces or one side surface of the transparent display device. When one side surface is used in the transparent display device, stability is high, but it is difficult to intuitively distinguish a surface enabling a touch from the other, and an input is performed on only one side surface. Accordingly, when characters and the like are input, there are disadvantages, such as a reduced input speed, and the like. Also, a User Interface (UI) using a three-dimensional (3D) screen in the transparent display device is recently introduced. However, a scheme for touching only one side surface is disadvantageous in that the user has difficulty in controlling the UI using a 3D screen. In order to overcome this disadvantage, portable terminal products are released, each of which includes a transparent display device, of which a touch screen is applied to both side surfaces.
When a touch input is allowed on both sides of a screen of the transparent display device, a 3D screen, a 3D application, and the like, can be more widely utilized by using a touch on each of the both sides of the screen. However, when a touch input is used on the both sides of the screen, a malfunction may occur. It is also necessary to efficiently, easily and conveniently configure the lock or unlock of the both sides of the screen and increase the availability of the transparent display device.
When the user grips and uses the portable terminal having the transparent display of which a touch screen is applied to both side surfaces, in the portable terminal having the transparent display, the touch screen touched by a palm of a hand of the user who grips the portable terminal may malfunction regardless of the intention of the user.
When both side surfaces of the portable terminal having the transparent display operate as the touch screen, the transparent display has a problem in that the user has difficulty in distinguishing one side surface in a lock state from the other in an unlock state among both side surfaces of the transparent display.
The present invention has been made to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present invention provides a method and an apparatus for controlling to lock or unlock in a portable terminal, in which a user can conveniently set the lock or unlock of touch screens on both sides of a transparent display or that of a touch screen on any one side thereof.
Another aspect of the present invention provides a method and an apparatus for controlling to lock or unlock in a portable terminal having a transparent display, which can automatically change a touch surface of the portable terminal, that a user grips and contacts, to a lock state and can remove a malfunction of the transparent display.
Another embodiment of the present invention provides a method and an apparatus for controlling lock or unlock in a portable terminal, which can adjust a corresponding transparency according to the lock and unlock of a display of the portable terminal and thereby, enable a user to intuitively and easily know whether the display of the portable terminal is set to the lock or unlock.
In accordance with an aspect of the present invention, a method for controlling to lock or unlock in a portable terminal having a transparent display capable of double-sided touch input and double-sided display is provided. The method includes activating the transparent display according to a lock state or an unlock state of the transparent display; displaying a lock or unlock area, which notifies whether a display surface is locked, in a preset area of at least one of display surfaces of the transparent display; and changing the lock state or the unlock state of the at least one of the display surfaces of the transparent display and displaying whether the changed state is the lock state or the unlock state in the lock or unlock area of the at least one display surface, when a touch input is received in the lock or unlock area.
In accordance with another aspect of the present invention, an apparatus for controlling to lock or unlock in a portable terminal is provided. The apparatus includes a transparent display that has two display surfaces and is capable of double-sided touch input and double-sided display; and a control unit configured to read the lock state or the unlock state of the transparent display from the memory, to activate the transparent display according to the lock state and the unlock state of the transparent display, to display a lock or unlock area, which notifies whether a display surface is locked, in a preset area of at least one of the display surfaces of the transparent display, and to change the lock state or the unlock state of the at least one of the display whether the changed state is the lock state or the unlock state in the lock or unlock area of the at least one display surface, when a touch input is received in the lock or unlock area.
The above and other aspects, features and advantages of the present invention will be more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which:
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements will be designated by the same reference numerals although they are shown in different drawings. Further, detailed descriptions related to well-known functions or configurations capable of making subject matters of the present invention unnecessarily obscure will be omitted.
Meanwhile, embodiments of the present invention shown and described in this specification and the drawings correspond to specific examples presented in order to easily explain technical contents of the present invention, and to help comprehension of the present invention, but are not intended to limit the scope of the present invention. It will be apparent to those having ordinary knowledge in the technical field, to which the present invention pertains, that it is possible to practice other modified embodiments based on the technical idea of the present invention as well as the embodiments disclosed herein.
Under the control of the control unit 160, the wireless communication unit 110 of the portable terminal 100 including the above-described elements establishes a communication channel for a voice call, a communication channel for a video call, a communication channel for transmitting data such as an image or a message, a communication channel for connecting to a network, and the like. Specifically, the wireless communication unit 110 establishes a voice call channel, a data communication channel, and a video call channel between mobile communication systems. The wireless communication unit 110 may further include a Radio Frequency (RF) transmission unit for upconverting the frequency of a signal to be transmitted and then amplifying the frequency-upconverted signal, and an RF reception unit for low-noise amplifying a received signal and then downconverting the frequency of the low-noise amplified signal, and the like.
The input unit 120 includes multiple input keys and function keys for receiving number and character information as input, and setting various functions. The function keys include arrow keys, side keys, hot keys, and the like, which are set to perform particular functions. The input unit 120 also generates a key signal related to a user setting and the function control of the portable terminal 100, and delivers the generated key signal to the control unit 160. The input unit 120 may be implemented by a QWERTY keypad, a 3*4 keypad, a 4*3 keypad, and the like, each of which includes multiple keys. Alternatively, the input unit 120 may be implemented by a QWERTY key map, a 3*4 key map, a 4*3 key map, a menu map, a control key map, and the like, each of which is displayed on the transparent display unit 140. When the transparent display unit 140 of the portable terminal 100 is supported in the form of a full touch screen, the input unit 120 may include only a side key formed on a side of a case of the portable terminal 100.
The audio processing unit 130 includes a speaker (SPK) for outputting audio data transmitted and received during a telephone call, audio data included in a received message, audio data obtained by reproducing an audio file stored in the storage unit 150, and the like, and a microphone (MIC) for collecting a voice of a user during a telephone call or other audio signals. The audio processing unit 130 may generate a corresponding effect sound when a first touch screen unit 141 or a second touch screen unit 142 as described below is set to lock or unlock. An effect sound may be omitted or replaced with a pre-stored effect sound according to a user setting.
The transparent display unit 140 includes the first touch screen unit 141 and the second touch screen unit 142, each of which recognizes a touch of the user as a command and generates a signal matched to the recognized touch of the user; and a screen unit 143 which is arranged between the first touch screen unit 141 and the second touch screen unit 142, displays a screen image, and adjusts a transparency and displays a screen according to the adjusted transparency. The transparent display unit 140 also has characteristics of a double-sided display. Specifically, the transparent display unit 140 has characteristics such that a screen is visible from both the front and back sides thereof, and an input is capable of being performed on both sides thereof.
The screen unit 143 displays a screen image, and may display a transparency of a screen by using a value selected from among consecutive values between a value representing transparentness and a value representing opacity under the control of the control unit 160. A lock/unlock area is disposed in a UI form at one side of the transparent display. The lock/unlock area is provided in the shape of a triangle, a rectangle, a circle, and the like, and is configured so as not to be affected by an unnecessary touch of the user.
For convenience of description, when the user grips the portable terminal having the transparent display is described, a front part of the portable terminal which faces the user is referred to as the “first touch screen unit 141”, and the rear part thereof which contacts the palm of the user is referred to as the “second touch screen unit 142.” However, the first touch screen unit 141 and the second touch screen unit 142 may be switched to perform functions of each other, and have no difference in performing a function of a process matched to a touch.
The sensor unit 170 which senses a force applied to the portable terminal 100 includes a grip sensor 171 which is mounted on a lateral surface of the portable terminal 100 and senses whether the user grips the portable terminal 100, and a motion sensor 172 which is mounted inside the portable terminal 100 and senses an operation of the portable terminal 100. The grip sensor 171 may be implemented by using a piezoelectric sensor, and the motion sensor 172 may be an acceleration sensor, a gyro sensor, or a sensor configured by combining the acceleration sensor and the gyro sensor.
The grip sensor 171 senses whether the user has gripped the portable terminal 100, and generates a grip signal when the user has gripped the portable terminal 100. When sensing that a touch signal is received as an input from any one of the first touch screen unit 141 or the second touch screen unit 142 when a grip signal is received as an input from the grip sensor 171, the control unit 160 determines that an unnecessary touch is input to the first touch screen unit 141 or the second touch screen unit 142 when the user grips the portable terminal 100. Based on the determination, the control unit 160 may set, to a lock state, one of the first touch screen unit 141 and the second touch screen unit 142 which has received the relevant touch signal as the input.
The motion sensor 172 senses the motion of the portable terminal 100. The control unit 160 determines which type of signal is a motion signal sensed by the motion sensor 172. When the sensed motion signal is a movement signal caused by rotating the portable terminal such that each of the first touch screen unit 141 and the second touch screen unit 142 is in a reverse direction, the control unit 160 reverses the lock/unlock states of the first touch screen unit 141 and the second touch screen unit 142, each of which is set to a lock state or an unlock state.
The storage unit 150 stores an application program required to perform functions according to an embodiment of the present invention, a key map or a menu map for operating the transparent display unit 140, and the like. The storage unit 150 also stores a UI which enables selective lock or unlock of the touch screen units, and the like.
The storage unit 150 may broadly include a program area and a data area. The program area stores an Operating System (OS) for booting the portable terminal 100 and operating each of the above-described elements, application programs for reproducing various files, and the like. Examples of the application programs includes an application for supporting a telephone call function of the portable terminal 100, a web browser for connecting to an Internet server, a Moving Picture Experts Group (MPEG) Audio Layer-3 (MP3) application program for reproducing a sound source, an image output application program for reproducing a photograph, and the like, and an application program for reproducing a moving image. Particularly, the program area according to an embodiment of the present invention stores a control program and a UI capable of controlling the lock and unlock of the transparent display unit 140 and controlling a corresponding transparency according to the lock and unlock of the transparent display unit 140.
The control unit 160 performs a control operation for displaying a corresponding transparency, according to a screen setting state which has been set by the user or according to the detection of lock/unlock states matched to a default setting. For example, the control unit 160 performs a control operation for displaying transparencies matched to a case in which the first touch screen unit 141 and the second touch screen unit 142 are both set to lock, a case in which the first touch screen unit 141 and the second touch screen unit 142 are both set to unlock, a case in which the first touch screen unit 141 is set to unlock and the second touch screen unit 142 is set to lock, and a case in which the first touch screen unit 141 is set to lock and the second touch screen unit 142 is set to unlock. For example, in the case of a lock state, the control unit 160 performs a control operation for displaying a transparency so as to be close to opacity, whereas in the case of an unlock state, the control unit 160 performs a control operation for displaying a transparency so as to be close to being completely transparent.
The control unit 160 performs a control operation for locking/unlocking the first touch screen unit 141 and the second touch screen unit 142 so as to be matched to lock/unlock inputs which are input to lock/unlock areas through the first touch screen unit 141 and the second touch screen unit 142 according to lock/unlock screen setting states. According to a setting, the control unit 160 may control the lock/unlock of at least one of the first touch screen unit 141 and the second touch screen unit 142 by using a touch which has been input through the first touch screen unit 141. Similarly, the control unit 160 may control the lock/unlock of at least one of the first touch screen unit 141 and the second touch screen unit 142 by using a touch which has been input through the second touch screen unit 142.
When sensing a grip signal through the grip sensor 171 and sensing, for example, a touch through the second touch screen unit 142, the control unit 160 sets the second touch screen unit 142 to lock. Further, the control unit 160 controls the lock/unlock of the first touch screen unit 141 and the second touch screen unit 142, and thereby can increase the convenience of the user.
In step S203, the control unit 160 controls the transparent display unit 140 to display a screen according to the sensed lock/unlock state of each screen. Meanwhile, the transparent display unit 140 displays a UI area capable of controlling lock or unlock (hereinafter referred to as a “lock/unlock area”) at one side thereof. Here, the lock/unlock area may be provided in an active state regardless of lock/unlock states, and may lock or unlock the transparent display unit 140 according to a touch input by the user.
Examples of display of a screen according to lock/unlock state of each screen are as follows. As a first example, the first touch screen unit 141 and the second touch screen unit 142 are both in a lock state. In the first example, a transparency of the transparent display unit 140 is reduced, and thereby the user is capable of visually recognizing that the first touch screen unit 141 and the second touch screen unit 142 are both in a lock state. As a second example, the first touch screen unit 141 is in a lock state, and the second touch screen unit 142 is in an unlock state. As a third example, the first touch screen unit 141 is in an unlock state, and the second touch screen unit 142 is in a lock state. In the second and third examples, the transparency of the transparent display unit 140 is represented as a preset transparency, and thereby the user is capable of easily knowing which screen is in a lock state and which screen is in an unlock state. As a fourth example, the first touch screen unit 141 and the second touch screen unit 142 are both in an unlock state. Hereinafter, the transparency of the transparent display unit 140 is displayed in such a manner as to be only affected by the second touch screen unit 142. That is, regardless of the lock or unlock of the first touch screen unit 141, when the second touch screen unit 142 is in a lock state, the transparency of the transparent display unit 140 is displayed on the transparent display unit 140 so as to be close to opacity; when the second touch screen unit 142 is in an unlock state, the transparency of the transparent display unit 140 is displayed on the transparent display unit 140 so as to be close to being completely transparent.
In step S204, according to the lock/unlock state of each of the first touch screen unit 141 and the second touch screen unit 142, the control unit 160 performs lock/unlock processing according to a user touch which has been input to a lock/unlock area through each of the first touch screen unit 141 and the second touch screen unit 142. The lock/unlock processing will be described in detail below with reference to

When the motion sensing signal is received in step S1402, in step S1403, the control unit 160 determines whether the motion sensing signal has been generated by rotation which changes directions in which the first touch screen unit 141 and the second touch screen unit 142 face. For example, the control unit 160 determines whether the motion sensing signal has been generated by a change in directions, in which the first touch screen unit 141 the second touch screen unit 142 respectively face, caused by rotation around 180 degrees of the portable terminal 100.
When it is determined in step S1403 that the motion sensing signal has been generated by rotating the directions in which the first touch unit 141 and the second touch screen unit 142 respectively face, in step S1404, the control unit 160 reverses lock/unlock states of the first touch screen unit 141 and the second touch screen unit 142. For example, when the first touch screen unit 141 is in the unlock state and the second touch screen unit 142 is in the lock state, if the motion sensor 172 senses that the directions have been mutually reversed, the control unit 160 sets the first touch screen unit 141 to be locked, and sets the second touch screen unit 142 to be unlocked. In response to the setting, the control unit 160 displays a screen, in such a manner as to reverse a left part and a right part or reverse an upper part and a lower part of the screen originally displayed in the transparent display unit 140.

In step S1601, when the user turns power on through the input unit 120, the control unit 160 performs a control operation for displaying an initial screen. Here, the control unit 160 displays, on one side of the transparent display unit 140, a lock/unlock area capable of locking or unlocking the first touch screen unit 141 and the second touch screen unit 142 regardless of the lock or unlock state of the first touch screen unit 141 and that of the second touch screen unit 142.
In step S1602, the control unit 160 determines whether a touch for locking or unlocking has been input to the lock/unlock area through the first touch screen unit 141. When it is determined in step S1602 that the lock touch or unlock touch has been input to the lock/unlock area through the first touch screen unit 141, in step S1603, the control unit 160 locks or unlocks the first touch screen unit 141. For example, when a touch for unlocking the first touch screen unit 141 has been input through the first touch screen unit 141, the control unit 160 unlocks the first touch screen unit 141.
In step S1604, the control unit 160 determines whether an atypical touch has been input through the second touch screen unit 142. The atypical touch may refer to touching the second touch screen unit 142 while the lock/unlock area is not being touched, or dragging in a direction other than a predetermined direction after the lock/unlock area is touched or maintaining the touch while the lock/unlock area is still being touched.
When it is determined in step S1604 that the atypical touch has been input through the second touch screen unit 142, in step S1605, the control unit 160 locks the second touch screen unit 142. For example, when a touch for unlocking the first touch screen unit 141 has been input through the first touch screen unit 141, the control unit 160 unlocks the first touch screen unit 141, and when an atypical touch has been input through the second touch screen unit 142, the control unit 160 locks the second touch screen unit 142. If the second touch screen unit 142 had been in a lock state, the atypical touch would not have any effect. In

In step S1802, the control unit 160 determines whether the second touch screen unit 142 is in a lock state. When it is determined in step S1802 that the second touch screen unit 142 is in the lock state, in step S1803, the control unit 160 controls the transparent display unit 140 to be displayed with a preset transparency matched to the lock state. When it is determined in step S1802 that the second touch screen unit 142 is in an unlock state, in step S1804, the control unit 160 controls the transparent display unit 140 to be displayed with a preset transparency matched to the unlock state.
Herein, the control unit 160 displays a transparency matched to the lock state of the second touch screen unit 142 in a nearly opaque state and displays a transparency matched to the unlock of the second touch screen unit 142 in a nearly transparent state. For example, when the second touch screen unit 142 is in the lock state, the user may control the transparent display unit 140 to be displayed in a nearly transparent state. When the second touch screen unit 142 is in the unlock state, the user may control the transparent display unit 140 to be displayed in a nearly opaque state. However, the transparency of the transparent display unit 140 can be displayed according to the intuition of the user by displaying the unlock state associated with transparentness and by displaying the lock state associated with opacity.
