As shown in FIG. 3, when a pointer such as a user's finger is close to the touch screen, the proximity sensor disposed in or near the touch screen detects this and outputs a proximity signal.

The proximity sensor may be configured to output different proximity signals according to a distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

A distance at which the proximity signal is output when the pointer approaches the touch screen is referred to as a detection distance. In short, by using a plurality of proximity sensors having different detection distances, the proximity signals output from the proximity sensors are compared, .

In FIG. 3, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d0), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d1, it is recognized as a proximity touch of the first proximity depth.

If the pointer is located on the touch screen at a distance d1 or less and less than the distance d2, the pointer is recognized as a proximity touch of the second proximity depth. When the pointer is spaced apart from the d2 distance by more than d3 distance on the touch screen, it is recognized as a proximity touch of a third proximity depth. If the pointer is located at a distance d3 or more on the touch screen, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity and proximity positions of the pointer to the touch screen, and perform various operation controls according to the various input signals.

4 is a flowchart illustrating an operation of a mobile terminal according to an embodiment of the present invention.

As shown, the operation process of the mobile terminal 100 according to an embodiment of the present invention may include entering a sleep mode state (S10).

The sleep mode state may mean that at least a portion of the mobile terminal 100 is in a deactivated state. For example, the power of the display 151 of the mobile terminal 100 may be cut off. By cutting off and deactivating power of the display 151, the power consumption of the mobile terminal 100 can be reduced. Entry into the sleep mode may be performed by a control operation of the controller (180 of FIG. 1) or a key operation of the user. For example, if the mobile terminal 100 is not operated for a predetermined time or more, the controller (180 of FIG. 1) may be in a sleep mode state by cutting off the power supplied to the display 151 of the mobile terminal 100. . However, in some cases, the power supply to the touch screen constituting the display 151 may not be completely blocked. For example, the display 151 including the backlight portion may be turned off, but the touch screen portion may be operated. In this case, in the sleep mode in which the display 151 is turned off, the user may touch the display 151 to wake the mobile terminal 100 from the sleep mode.

In step S20, the mobile terminal 100 in the sleep mode state enters the active mode state.

The active mode state may be a state in which each part of the mobile terminal 100 including the display 151 is activated. For example, it may be a state in which power is supplied to a backlight that is not supplied with power when in a sleep mode. In the active mode, the user may operate the mobile terminal 100 to execute various functions such as a call and a message writing. As described above, the entry into the active mode may be performed through a control signal of the controller (180 of FIG. 1) or a user's manipulation. For example, the user may enter the active mode by manipulating a key of the mobile terminal 100 or by activating the mobile terminal 100 by touching a touch screen area. In addition, when the mobile terminal 100 receives a call, the controller 180 of FIG. 1 may supply power to the display 151 to activate the mobile terminal 100.

When entering the active mode state, in operation S30, it may be determined whether a touch operation with respect to the display 151 is present in the sleep mode state.

The display 151 may include an electrophoretic film layer. The electrophoretic film layer may represent an image by moving particles (P of FIG. 7) containing dye in a specific direction. For example, the text may be expressed by bringing particles (P of FIG. 7) including white and black dyes closer or farther away from the surface of the display 151. Particles (P in FIG. 7) may be positively or negatively charged. Thus, if the environment around the particle (P in FIG. 7) is changed from positive to negative or vice versa, the particle (P in FIG. 7) may be moved and text may be represented. As will be described in more detail in the corresponding section, the change in the environment around the particle (P in FIG. 7) may be made when the dielectric or conductor including the user's fingers F1 and F2 is moved closer or farther from the display 151. . The display 151 to which the electrophoretic film layer is applied may be used to display an e-book.

If there is a touch operation with respect to the display 151 in the sleep mode state, the touch trace may remain on the display 151 due to the movement of the particles (P of FIG. 7) included in the electrophoretic film layer. That is, as described above, even when the electricity is not applied in the sleep mode, the fingers F1 and F2 of FIG. 7 may have a constant polarity of charge. For example, suppose that the fingers (F1, F2 in FIG. 7) have a positive polarity, when the fingers (F1, F2 in FIG. 7) approach the display 151, particles having negative polarity (FIG. 7). P) is away from the finger (F1, F2 of FIG. 7), the particle having a positive polarity (P of FIG. 7) can move closer to the finger. When the particles (P in FIG. 7) move, the display 151 may display a trajectory of fingers (F1 and F2 in FIG. 7).

When entering the active mode from the sleep mode state, the controller (180 of FIG. 1) may determine whether there is a touch operation with respect to the display 151 in the slim board state. For example, by scanning the distribution of particles (P in FIG. 7) in each capsule C, it is possible to obtain information on the existence of the touch operation and the trajectory of the movement.

If there is a touch operation with respect to the display 151 in the sleep mode state, an operation (S40) of acquiring a touch trace may be performed.

As described above, the controller (180 of FIG. 1) may acquire the touch trajectory through a method of scanning a distribution of particles (P of FIG. 7). Among the particles (P in FIG. 7), the first particle (BP in FIG. 7) may have a positive charge, and the second particle (WP in FIG. 7) may have a negative charge. When the amount of charge is measured at the bottom or top of the capsule (C in FIG. 7), the controller (180 in FIG. 1) determines what kind of particles (P in FIG. 7) have moved to the bottom or top of each capsule (C in FIG. 7). ) Can be judged. By repeating this scan operation for each capsule (C of FIG. 7), the controller (180 of FIG. 1) can know what trajectory is formed by the touch.

If the touch trajectory has been acquired, step S50 of executing a function corresponding to the obtained touch trajectory may proceed.

The function corresponding to the touch trace may be a memo function, an alarm setting function, a dialing function, or the like. For example, when the memo is recorded by touching the display 151 in the sleep mode state, when entering the active mode state, the controller (180 of FIG. 1) may execute the memo function and store the trajectory recorded by the user. Since the necessary memo can be immediately stored in the sleep mode and the memo can be stored in the active mode, the inconvenience of turning on the mobile terminal 100 and executing the memo function can be eliminated.

5 is a diagram illustrating entering a sleep mode state of the mobile terminal of FIG. 4.

As shown, the mobile terminal 100 according to an embodiment of the present invention may be in an active mode state or a sleep mode state.

As shown in FIG. 5A, the mobile terminal 100 may be in an active mode in which the display 151 or the like operates. In the active mode, the backlight of the display 151 may operate. Due to the operation of the backlight, the mobile terminal 100 may use relatively large power in the active mode.

As shown in FIG. 5B, the mobile terminal 100 may be in a sleep mode in which the display 151 or the like does not operate. In the sleep mode state, the backlight of the display 151 may not operate. Therefore, in the sleep mode, only minimal power for call waiting and the like can be used.

6 is a diagram illustrating a process of acquiring a touch trace of the mobile terminal of FIG. 4.

As shown in the drawing, the mobile terminal 100 according to an embodiment of the present invention may execute a function corresponding to a touch trace by a user's touch operation, and the function may be an alarm setting function.

As shown in FIGS. 6A and 6B, when in the sleep mode, the user may perform a touch operation on the display 151 using a finger or the like. In this case, the user may input a character, a symbol, or the like indicating a desired function. For example, in order to execute the alarm setting function, a touch operation of writing a letter “alarm” with a finger or the like may be performed on the display 151. You can also enter a time that can be associated with the alarm function. 6 (a) and 6 (b) may be performed when the mobile terminal 100 is in the sleep mode and may not follow the display method of the display 151. That is, it means that it may be a character display by the action of the electrophoretic film layer provided on the bottom or top of the display 151. Despite the sleep mode, a method of inputting a text by a user's touch operation will be described in detail in the corresponding part.

As shown in (c) of FIG. 6, when the mobile terminal 100 in the sleep mode enters the active mode, the controller (180 of FIG. 1) may scan the contents input by the user in the sleep mode. Can be. In addition, a specific function may be executed based on the scanned contents. That is, as shown in (a) and (b) of FIG. 6, when a user inputs a time for setting an alarm, the controller (180 of FIG. 1) that scans this executes the alarm setting function. The content may be displayed through the first popup window P1.

7 is a view conceptually illustrating the operation of the electrophoretic film layer in the mobile terminal of FIG.

As shown in the drawing, the display 151 may include a liquid crystal display layer 163 and an electrophoretic film layer provided on the liquid crystal display layer 163. In the electrophoretic film layer, the position of the particle P is changed according to the change of the electric charge by the fingers F1 and F2 and the like, and the locus can be displayed. 7 conceptually illustrates the display 151 for understanding, the scale of each configuration may be different from the actual one. For example, although the capsule (C) is largely represented in FIG. 7, this is largely shown for convenience of understanding and may be smaller than the actual size.

The liquid crystal display layer 163 may have a structure including at least one of LCD, LED, OLED, and backlight. The liquid crystal display layer 163 may emit light when the mobile terminal 100 is in an active mode and display information.

The electrophoretic film layer may include an upper substrate 161, a lower substrate 162, and a capsule (C). The upper substrate 161 may be formed of a substantially transparent material. Therefore, the image displayed on the liquid crystal display layer 163 and the image due to the movement of the particle P may be displayed to the outside. The lower substrate 162 serves to support the structure, and if necessary, may include a wiring for supplying power to change the amount of charge in a portion of the capsule (C). That is, it means that the image can be displayed by moving the particles P not only when the amount of charge is changed by the user's fingers F1 and F2 but also by the control signal of the controller (180 of FIG. 1). .

The capsule C may have a configuration corresponding to a pixel included in the liquid crystal display layer 163. That is, it means that one point can be displayed by one capsule (C). The capsule (C) may be filled with a transparent solution (OL). Capsule C may form one layer. That is, it means that the first, second, third capsules (C1, C2, C3) can be arranged side by side adjacent to each other.

The first capsule C1 may be in a state in which the fingers F1 and F2 of the user are not located nearby. When a dielectric or a conductor such as the user's fingers F1 and F2 is not present in the vicinity, the first and second particles BP and WP inside the first capsule C1 may be aligned according to unique charge characteristics. . The first particle BP may have a negative charge characteristic, and the second particle WP may have a positive charge characteristic. If the lower substrate 162 has the positive charge characteristic, the first particle BP having the negative charge characteristic is below the first capsule C1, and the second particle WP having the positive charge characteristic is made of the first particle BP. It may be located above one capsule (C2). If the first particle BP is dyed in black and the second particle WP is dyed in white, the white second particle WP is positioned on the upper substrate 161 so that the first particle BP is dyed in white. In view, the first capsule C1 may be represented by a white dot.

The second capsule C2 may be in a state where the user's finger F1 is in proximity. The finger F1 of the user, which is a dielectric, may have a positive charge characteristic. Therefore, when the finger F1 approaches, the first particle BP having the negative charge characteristic may gradually move toward the upper substrate 161 in the direction of the finger F1. In addition, the second particle WP having positive charge characteristics may move toward the lower substrate 162 in the opposite direction of the approaching finger F1. In this case, the magnitude of the positive charge characteristic of the lower substrate 162 may be smaller than the magnitude of the positive charge characteristic of the finger F1. Therefore, as the finger F1 approaches, the first and second particles BP and WP may move.

The third capsule C3 may be in a state in which the user's finger F1 is in contact with the upper substrate 161. When the finger F2 having the positive charge characteristic contacts the upper substrate 161, the positive charge characteristic may be maximized. Therefore, movement of the first particle BP to the upper side of the third capsule C3 and movement of the second particle WP to the lower side of the third capsule C3 may be accelerated. In addition, when the finger F1 contacts the upper substrate 161, some of the charges at the ends of the finger F1 may move to the upper substrate 161. The positive charges moved to the upper substrate 161 may cause the moved particles P to be fixed at the positions. Therefore, even when the finger F1 is moved away from the upper side of the third capsule C3, the first particle (moved to the upper side of the third capsule C3) due to the influence of the positive charge moved to the upper substrate 161 ( The state of BP) can be maintained as it is. By allowing the first particle BP to be moved above the third capsule C3 to be fixed at the position, the third capsule C3 may be displayed as a black dot on the display 151.

8 to 11 are diagrams illustrating an execution process of a function corresponding to a touch trace in the mobile terminal of FIG. 4.

As shown in these figures, the mobile terminal 100 according to an embodiment of the present invention can execute various functions corresponding to the touch trace received in the sleep mode state. Hereinafter, various functions corresponding to the touch trace will be described in detail with reference to the drawings.

As shown in FIG. 8, one of the functions corresponding to the touch trace may be a memo function.

As shown in FIG. 8A, in the sleep mode, the user may touch the display 151. That is, the user may perform a touch operation of dragging the desired letter or symbol to the display 151 without any additional manipulation. As described above, letters or symbols may be displayed along the user's touch trajectory by the action of the electrophoretic film layer. Therefore, the user may be able to immediately check the contents recorded by the user.

As shown in FIG. 8B, when entering the active mode, the memo function may be executed. That is, the function based on the contents input by the user may be executed in the sleep mode without any additional operation. Without an intermediate procedure of turning on the mobile terminal 100 in the sleep mode state and executing the memo function, it is possible to immediately save the contents recorded in the sleep mode state when entering the activated board state, thereby improving convenience of use.

As shown in FIG. 9, one of the functions corresponding to the touch trace may be a telephone function.

As shown in FIG. 9A, when the user is in the sleep mode, the user may touch the display 151 to enter a phone number. In this case, the user may input an indicator corresponding to a function to be executed in order to clarify what function he / she wants. For example, if you want to execute the phone function, you can enter the text "telephone", and the text "telephone" can be an indicator. In FIG. 9A and the like, a case in which the indicator is text is taken as an example, but the indicator may be a symbol, a figure, or the like. For example, the triangular figure may be a case where the telephone function is to correspond.

As shown in (b) of FIG. 9, when entering the active mode, the controller (180 of FIG. 1) may perform a call function of calling a number input in the sleep mode.

As shown in FIG. 10, one of the functions corresponding to the touch trace may be a function of uploading text to a social network service (SNS) server.

As shown in FIG. 10A, when the user is in the sleep mode, the user may input text to be uploaded to a specific social network service server on the display 151.

As illustrated in FIG. 11A, when the user is in the sleep mode, the user may input the search word by touching the display 151.

As shown in (b) of FIG. 11, the search function may be executed when entering the activivo mode state.

FIG. 12 is a diagram illustrating activation of a display or electrophoretic film layer in the mobile terminal of FIG. 4.

As shown, the mobile terminal 100 according to an embodiment of the present invention may selectively use an electrophoretic film layer or LCD or LED and backlight according to the user's input in the sleep mode. For example, the controller (180 of FIG. 1) may be an electrophoretic film layer depending on whether the touch is a touch of a specific point of the display 151, how long the touch lasts, and what trajectory of the touch moves. May be activated or an existing display layer (163 of FIG. 7) including an LCD or LED.

As shown in FIG. 12A, the user may touch the display 151 of the mobile terminal 100. When the user touches the display 151 of the mobile terminal 100, the electrophoretic film layer may be activated as shown in FIG. 12C. For example, when the user touches the display 151 instead of the key button of the mobile terminal 100, the electrophoretic film layer may be activated.

As shown in FIG. 12B, when the display 151 is touched, an existing display layer 163 of FIG. 7 including an LCD or an LED may be activated. In a sleep mode in which an image is not displayed on the display 151, when a user touches a specific point of the display 151, the controller (180 of FIG. 1) may activate the display layer (163 of FIG. 7). Alternatively, when the key button of the mobile terminal 100 is pushed, the controller (180 of FIG. 1) may activate the display layer (163 of FIG. 7).
