Meanwhile, the mobile terminal 200 according to this modified example may include a case 201 accommodating the flexible display unit 251 . The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251 .

In addition, a battery (not shown) provided in the mobile terminal 200 may also be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251 . In order to implement the battery, a stack and folding method in which battery cells are stacked upward may be applied.

State deformation of the flexible display unit 251 is not limited to external force. For example, when the flexible display unit 251 has a first state, it may be transformed into a second state by a command of a user or an application.

3 is an exploded perspective view of a mobile terminal according to an embodiment of the present invention. In FIG. 3, the mobile terminal faces the front in the Z-axis direction, the Y-axis direction represents the top of the mobile terminal, and the X-axis direction represents one side of the mobile terminal.

A mobile terminal 100 according to the present invention includes a glass 300, a touch sensor 402, a light sheet 420, a light guide plate 430, a reflective sheet 440, a frame 500, a back cover 510, and PCB 520 may be included.

The glass 300 may be located on the front of the mobile terminal 100 . The glass 300 may be made of a transparent material. The glass 300 is directly touched by a user's finger and can protect internal components of the mobile terminal 100 .

The touch sensor 402 may obtain a user's touch operation. The touch sensor 402 may be of a pressure-sensitive or capacitive type.

The optical sheet 420 may serve to make brightness uniform. For example, the light sheet 420 is composed of a plurality of prism sheets, which means that light from the light source 450 can be uniformly emitted to the front surface.

The light guide plate 430 may diffuse the light from the light source 450 to the entire surface of the light guide plate 430 by using a property of total reflection. That is, in the case of the edge type, light emitted from the light source 450 located on one side of the light guide plate 430 is totally reflected inside the light guide plate 430 and can be diffused throughout the light guide plate 430 . The diffused light may be emitted toward the light sheet 420 through irregularities on the upper side of the light guide plate 430 .

The reflective sheet 440 may be located on the rear side of the light guide plate 430 . The reflective sheet 440 may reflect light traveling toward the rear toward the front.

The frame 500 may form the exterior of the mobile terminal 100 . The frame 500 may have a form in which a plastic material or the like is injected.

4 and 5 are diagrams showing each state of the mobile terminal.

As shown in these drawings, the mobile terminal 100 according to an embodiment of the present invention may be in various states. For example, this means that the control unit 180 of the mobile terminal 100 can change the state of the display unit 151 according to conditions.

As shown in FIG. 4 , the display unit 151 is in a first state in which the display unit 151 is turned on, in a second state in which the display unit 151 is dimmed, and in a state in which the display unit 151 is dimmed. It may be in a specific state including an off third state. For example, when the display unit 151 requires an activated state, such as when a user's manipulation is input, it may be in the first state. When a predetermined time elapses in the first state, the second state may be switched to reduce power consumption. When there is no user input for a predetermined period of time after switching to the second state, the state may be switched to the third state to further reduce power consumption. Alternatively, the first state may be converted to the third state without going through the second state.

As shown in FIG. 5 , the display state may be changed according to the state of the display unit 151 of the mobile terminal 100 .

As shown in (a) of FIG. 5 , in the first state, the display unit 151 may display an image with a first brightness. The first brightness may be brightness when the backlight of the mobile terminal 100 operates at maximum or close to maximum brightness. The first brightness may be changed to correspond to ambient illumination.

As shown in (b) of FIG. 5 , in the second state, the display unit 151 may display an image with a second brightness. The second brightness may be brightness when the backlight of the mobile terminal 100 is turned off. The second state may be a dimming state. That is, an image may be displayed on the entire display unit 151, but the backlight may be turned off.

As shown in (c) of FIG. 5, in the third state, the display unit 151 may be turned off. That is, it means that the display unit 151 can be inactivated. The mobile terminal 100 may be in a state of waiting for an input.

6 to 10 are diagrams illustrating operations of a mobile terminal according to an embodiment of the present invention.

As shown in these drawings, the mobile terminal 100 according to an embodiment of the present invention can operate in a state in which only a specific part of the display unit 151 is selectively activated. The mobile terminal 100 according to an embodiment of the present invention can selectively respond only to a user's touch input on an activated area. The mobile terminal 100 according to an embodiment of the present invention can minimize power consumption through minimized activity of the display unit 151 .

As shown in (a) of FIG. 6 , the entire area of the display unit 151 may be in an activated state. For example, it means that it may be in the above-mentioned first state. In the first state, the display unit 151 may display an image on the entire area. In the first state, the display unit 151 may obtain a user's touch input through the entire area.

As shown in (b) of FIG. 6 , the display unit 151 may be in a fourth state in which a partial region is activated.

The fourth state in which a part of the region is activated may be operated after a certain period of time has elapsed since the above-described second state. For example, this means that an operation in a fourth state in which a partial region is selectively activated may be initiated instead of entering a third state in which the entire region is turned off after the dimming state.

The activation area A may be a watch area and/or an area for notifying reception of a message or the like.

In the fourth state, the display unit 151 of the mobile terminal 100 can selectively operate only the active area A. In other words, it can be said that only the activation region A is selectively activated. In other words, it can be said that regions other than the activation region A may have inactivation or reduced activation.

In the fourth state, minimum information required by the user may be provided. That is, information such as a clock may be provided through the activation area A. In that information can be provided, the fourth state is different from the third state in which the entire area is deactivated. The fourth state differs from the first state in which all regions are activated in that only a part of the region is activated. The fourth state is different from the second state in which only the backlight is entirely inactivated in that an image is not displayed in the inactive region B except for the active region A.

The activation area A may be substantially the same area as the position of the clock display area CI where the time is displayed when the mobile terminal 100 is in the first state and/or the second state. Therefore, even when the activation area A is displayed by entering the fourth state as soon as the first state or the second state is converted to the third state, the user can recognize the time information without a sense of heterogeneity.

As shown in (a) of FIG. 7 , a clock may be displayed in the active area A. This may be useful information for the user in that the mobile terminal 100 is often used to check the current time. This point is related to the user's convenience and / or convenience when considering the case where the user additionally manipulates the mobile terminal 100 to switch to the first state when the display unit 151 is turned off in the third state in the conventional case. Alternatively, it can be seen that efficient use of resources of the mobile terminal 100 has become possible. That is, the user can check necessary information at any time without additional manipulation. For example, when the mobile terminal 100 is in the first and second states as well as when it enters the third state, it means that time information and the like can be immediately checked through the active area A. In addition, current consumption of the mobile terminal 100 can be minimized despite the display of information by allowing only the active area A to be operated.

As shown in (b) of FIG. 7 , additional information AF may be displayed in the activation area A. The additional information (AF) may be information about an event that has occurred, such as whether a message has been received or not, whether or not a call has been missed.

The additional information AF may not change the display position of previously displayed time information in the activation area A. That is, it means that the position and/or size of the visual information may not be changed due to the display of the additional information AF. Accordingly, the visual information basically displayed in the activation area A may be continuously displayed at a specific location.

As shown in FIG. 8, the active area A of the mobile terminal 100 according to an embodiment of the present invention may be changed based on a specific criterion. Therefore, the user can intuitively recognize that the current state is in a predetermined specific state even by only looking at the location of the active area A.

As shown in (a) to (c) of FIG. 8 , the active area A may be displayed on the first display area 151a to the third display area 151c.

The controller 180 may change the location of the active area A according to specific conditions. For example, the specific condition may be the current time. For example, if the present day belongs to the morning, the active area A is displayed on the first display area 151a, if the current day belongs to the afternoon, the active area A is displayed on the second display area 151b, and the current day is evening. , it means that the active area A can be displayed on the third display area 151c. The user can intuitively recognize a specific state according to the location and area of the active area A that change according to conditions and/or displayed information.

As shown in FIG. 9 , the controller 180 of the mobile terminal 100 according to an embodiment of the present invention may perform step S10 of entering the fourth state.

As described above, the fourth state may be a state progressed at the same time as the entry of the third state progressed after the first state or the second state or in place of the third state. That is, the fourth state means that the fourth state can be entered from the first and second states without entering the third state or a state included in the third state.

In the fourth state, a step (S20) of determining whether or not an input is made to the activation area A may be performed.

If there is an input to the active area (A), a step (S30) of performing a response corresponding to the input is performed, and if there is an input to an area other than the active area (A), the step of not responding to the input (S40) may proceed. That is, when a user's touch input is applied to the activation area A, it means that a corresponding operation can be performed. This means that when a user's touch input is applied to the inactive area B, a corresponding operation may not be performed.

As shown in FIG. 10 , the controller 180 may perform different operations according to the position of the user's touch input.

As shown in (a) of FIG. 10 , an active region A and an inactive region B may exist. The user may touch the inactive region B with a finger F or the like.

When the inactive area B is touched, the controller 180 may not perform an operation corresponding to the user's touch input. Therefore, it is possible to prevent a situation in which the entire mobile terminal 100 is activated due to a user's unconscious touch.

As shown in (b) of FIG. 10 , the user may touch the active area A with a finger F or the like. For example, this means that an additional information (AF) area notifying that a message has been received can be touched.

When the active area A is touched, the controller 180 may perform an operation corresponding to the user's touch input. For example, this means that the entire display unit 151 including the non-active area B can be activated. Accordingly, the content of the received message may be displayed on the entire display unit 151 .

11 to 20 are diagrams illustrating the configuration of a mobile terminal light guide plate according to various embodiments of the present invention.

As shown in these drawings, the mobile terminal 100 according to an embodiment of the present invention may include a light guide plate 430. The light guide plate 430 according to an embodiment of the present invention may guide the light of the light source 450 to a specific area. For example, it means that the light of the light source 450 can be guided to the active area (A). Accordingly, only the active area A may be selectively illuminated.

As shown in FIG. 11 , a light source 450 may be positioned on at least one side of the light guide plate 430 . The light source 450 may operate according to a control signal from the controller 180 . Light from the light source 450 is totally reflected within the light guide plate 430 and may be diffused to the entire surface of the light guide plate 430 . Light diffused into the light guide plate 430 may be emitted toward the front surface of the light guide plate 430 . Light emitted toward the front of the light guide plate 430 may be finally emitted to the outside through the glass 300 .

As shown in FIG. 12 , a pattern LP formed in the longitudinal direction of the light guide plate 430 may be formed on the light guide plate 430 . For example, this means that the pattern LP may be formed in the vertical direction of the mobile terminal 100 .

The pattern LP may be formed on one side of the light guide plate 430 . For example, it may be formed on the upper side of the light guide plate 430 . For example, it may be formed on a surface adjacent to glass (300 in FIG. 11 ) among several surfaces of the light guide plate 430 .

The pattern LP may be concavo-convex formed on at least a portion of the light guide plate 430 . For example, it means that the upper surface of the light guide plate 430 may be uneven formed in the longitudinal direction of the light guide plate 430 . For example, when the light guide plate 430 is at the first height H1, the pattern LP may be at the second height H2. The second height H2 may be greater than the first height H1.

13 shows a cross section of the light guide plate 430 in the I-I direction.

As shown, the pattern LP of the light guide plate 430 may include valleys V and crests R. The first height H1 extends from the bottom surface of the light guide plate 430 to the valley V, and the second height H2 extends to the crest R.

One or a plurality of patterns LP may form a certain area. For example, the first area A1 and the second area A2, and the second area A2 and the third area A3 may be divided by the valley V.

If the area is divided, the area in which the light generated from the light source 450 is diffused may be limited. For example, light introduced into the second area A2 may be diffused within the second area A2. That is, straightness of light can be secured along the pattern LP. That is, it means that the light introduced into the second area A2 may not pass over to the first or third areas A1 and A3.

As shown in (a) of FIG. 14 , the first light source 450a among the light sources 450 may be selectively turned on. The first light source 450a may include a plurality of LEDs. Light emitted from the turned-on first light source 450a may propagate through a fan-shaped diffusion path LR. That is, it means that light can be diffused throughout the glass 300 rather than selectively illuminating a specific area. Therefore, it may not be appropriate to selectively illuminate only a specific area.

As shown in (b) of FIG. 14 , when the pattern LP is formed on the light guide plate 430, the light propagation path may be affected by the pattern LP. For example, if the pattern LP is formed in the vertical direction of the mobile terminal 100, it means that the light emitted from the light source 450 is guided by the pattern LP and can travel in the vertical direction. Accordingly, when the first light source 450a emits light, the diffusion path LR may be a region below the first light source 450a.

As shown in FIG. 15, the quality of illumination for the active area A may vary according to the diffusion path.

FIG. 15(a) shows a case where the diffusion path LR is radial, as in FIG. 14(a). As shown, when a radial diffusion path LR is formed, a diffusion region LEA including an active region A may occur. That is, it means that the surroundings of the part requiring illumination, such as the current time, can be illuminated. If the diffusion area LEA exists, the emotional quality of the user of the mobile terminal 100 may deteriorate.

FIG. 15(b) shows a case in which the diffusion path LR is straight as in FIG. 14(b). As shown therein, when the linear diffusion path LR is formed, only the active region A may be illuminated. Accordingly, the quality perceived by the user may be improved.

As shown in FIGS. 16 to 18 , the light guide plate 430 according to another embodiment of the present invention can selectively illuminate a specific area.

As shown in these figures, the light guide plate 430 may be composed of a plurality of regions. For example, the light guide plate 430 may include first to third light guide regions 430a, 430b, and 430c.

The first to third light guiding regions 430a, 430b, and 430c may overlap each other. For example, the second light guiding area 430b is positioned above the first light guiding area 430a and the third light guiding area 430c is positioned above the second light guiding area 430b. ) can be configured.

The first to third light guiding regions 430a, 430b, and 430c may emit light incident therethrough only through each. For example, light incident to the first light guiding area 430a through the third light source 450c is propagated through the first light guiding area 430a, and then the first radiation area ( A1). Light incident to the second and third light guiding areas 430b and 430c through the second and first light sources 450b and 450a is also propagated along the second and third light guiding areas 430b and 430c, respectively, and then the second and third light guiding areas 430b and 430c respectively. (430b, 430c) may be emitted to the second and third radiation areas A2 and A3 on the front side.

19 illustrates a light guide plate 430 according to another embodiment of the present invention.

As shown, the light guide plate 430 may be formed as one without being physically separated. A shielding layer P may be present inside the light guide plate 430 .

The shielding film P can partition the light guide plate 430 into a plurality of regions. The shielding film P may be integrally formed with the light guide plate 430 . For example, this means that the light guide plate 430 may be insert-injected.

A plurality of light blocking plates P may be present. For example, this means that the first and second light blocking plates P1 and P2 may be spaced apart from each other and disposed side by side.

The first and second light blocking plates P1 and P2 may prevent light from one area from spreading to another area. For example, light emitted from the second light source 450b may propagate between the first and second light blocking plates P1 and P2.

As shown in FIG. 20, the mobile terminal 100 according to an embodiment of the present invention can reduce power consumption. That is, since only one area of the display 151 is selectively illuminated rather than the entire area, it means that less power can be consumed than in a normal state. In other words, since only a part of the light source 450 is operated, it means that a necessary part can be illuminated with less power than when the entire light source 450 is operated. According to experiments, when the normal power consumption is 1, it can be seen that the operation of the display 151 according to an embodiment of the present invention represents a power consumption of about 0.4. Such a state may be a state of using higher power than a state in which the display 151 is turned off and a state of using less power than a state in which the display 151 is turned on. Therefore, as a whole, the mobile terminal 100 can be used with less power than when the display 151 is repeatedly turned on to check the minimum required information such as the current time.

21 to 23 are diagrams illustrating the arrangement of light sources for mobile terminals according to various embodiments of the present invention.

As shown in these drawings, the mobile terminal 100 according to an embodiment of the present invention can change the position of the light source 450. For example, this means that the positions of at least some of the light sources 450 may be changed to correspond to the active area A.

As shown in (a) of FIG. 21 , the light source 450 may be located on the upper side of the light guide plate 430 . That is, it means that it may be located in the upper area UE of the light source 450 based on the longitudinal direction of the mobile terminal 100 . The activation area (A) means that it may be located on the upper side of the mobile terminal 100 . For example, the active area A may be displayed at a position approximately 1/3 to 1/5 of the upper side of the display 151 in the longitudinal direction. Therefore, it means that the light source 450 can be disposed above the mobile terminal 100 for effective and selective illumination of the active area A.

As shown in (b) of FIG. 21 , the light source 450 may be located in the lower area DE of the light guide plate 430 . A lower area of the light guide plate 430 may have a relatively large bezel width. Therefore, it may be an advantageous structure for mounting related accessories such as the light source 450.

As shown in (c) of FIG. 21 , the light sources 450 may be distributed in the upper area UE and the lower area DE. For example, the first and third light sources 450a and 405c may be disposed in the lower area DE, and the second light source 450b may be disposed in the upper area UE. The second light source 450b disposed in the upper area UE may be a light source 450 that is close to the active area A. In other words, it may be the light source 450 corresponding to the central area CA where the active area A is located. Such a structure can effectively illuminate the active region A.

As shown in FIG. 22 , the shape of the light guide plate 430 and/or the position of the light source 450 may be changed to effectively illuminate the active area A.

As shown in (a) and (b) of FIG. 22 , the activation area A may be located at a first distance H1 or a second distance H2 from the top. The second distance H2 may be smaller than the first distance H1. That is, to the user of the mobile terminal 100, the second activation area A2 may appear closer to the top than the first activation area A1. This can be clearly understood when considering that the display 151 corresponds to an area other than the protruding area PA where the light guide plate 430 protrudes upward.

It may be necessary to space a certain amount or more between the light source 450 and the activation area A. This can be clearly understood when considering that light emitted from each light source 450 spreads out and overlaps with another adjacent light source 450 and requires a distance to form an illuminance of a certain level or more. Therefore, as shown in (b) of FIG. 22, when the second active area A2 is to be displayed in a form close to the top of the display 151, the corresponding second light source 450b is moved upward. You may need to do

A user observes the display 151. Therefore, from the user's point of view, the second activation area A2 may be recognized as being closer to the top of the display 151 than the first activation area A1.

As shown in FIG. 23 , positions of the first light source 450a and the second light source 450b may be different. For example, the first light source 450a may be disposed in the lower area DE, and the second light source 450b may be disposed in the upper area UE.

A concave portion RA may be formed in the upper area UE corresponding to the first light source 450a disposed in the lower area DE. For example, this means that at least a portion of the PCB (F) on which various electronic components necessary for the operation of the mobile terminal 100 are mounted may be removed.

A camera module or the like may be coupled to the recessed portion RA. A camera module or the like may be produced through a separate process. Due to high-performance cameras such as resolution, the camera module may be thick. Due to the formation of the concave portion (RA) in which a portion of the PCB (F) is cut, a camera module or the like that is thicker than before can be mounted on the corresponding area. The first light source 450a may be located in the lower area DE due to the concave portion RA.

24 and 25 are diagrams illustrating a gate configuration of a mobile terminal according to an embodiment of the present invention.

As shown in these drawings, the mobile terminal 1000 according to an embodiment of the present invention may include a gate divided by region. The gate may be a path for inputting a display signal to the display 151. For example, the controller 180 may apply a control signal through a gate, and the display 151 may display an image according to the control signal applied through the gate. It can be considered that the display 151 is turned off. Conventionally, when the entire display 151 is turned off, the entire gate can be turned off. Therefore, even when only a part of the display 151 is used, the entire gate must be turned on. Therefore, power consumption had to be maintained to a certain extent or more regardless of the range of the displayed area.

As shown in FIG. 24 , the gate may include first and second gates G1 and G2. The first gate G1 may correspond to the active region A, and the second gate G2 may correspond to the inactive region IA. The first gate G1 and the second gate G2 may be separately applied with a control signal by the control unit 180 . In other words, it means that the first gate G1 and the second gate G2 can operate independently. In other words, when the first gate G1 is turned on, the second gate G2 may be turned off. In other words, it means that a signal can be input to the first gate G1 with a first frequency and a signal can be input to the second gate G2 with a second frequency different from the first frequency. In other words, it means that the first gate G1 and the second gate G2 are physically separated.

Since the first gate G1 and the second gate G2 are separated, the control unit 180 may operate by separating the active region A and the inactive region IA. For example, this means that the active area A can be turned on to display an image and the inactive area IA can be turned off. Therefore, it is possible to prevent loss of power due to turning on even the inactive area IA where display of an image is not necessary.

As shown in FIG. 25, the first and second gates G1 and G2 may be controlled in different states. Therefore, the resources of the mobile terminal 100 can be optimized and used.

As shown in (a) of FIG. 25, the driving power may be in the first state (S1). Driving power in the first state S1 may be changed at a time point t1. For example, this means that the active area A can maintain the first state S1 and the inactive area IA can change to the second state S2.

At the time point t1, only a part of the display 151 may be activated. For example, it may be a case where a user's manipulation of the mobile terminal 100 is not input for a certain period of time or more, or when the user changes the state of the mobile terminal 100 to a partially active state.

After time t1, the driving power for the active area A and the inactive area IA may be different. For example, this means that the first state S1 can be maintained for the active area A and the second state S2 can be achieved for the inactive area IA. Resources of the mobile terminal 100 can be used more effectively because the driving power can be lowered for parts that do not actually need to display images.

As shown in (b) of FIG. 25, the scan rate can be changed after the time point t1. For example, before time t1, an image may be displayed at a scan rate of P1 for both the active area A and the inactive area IA. When the time point t1 elapses, an image may be displayed at a scan rate of P2 for the active area A, and an image may be displayed at a scan rate P3 for the inactive area IA.

When the scan rate is changed, the frequency of displaying images on the display 151 may be changed. If the frequency of displaying images on the display 151 is lowered, power consumption can be reduced.

P1 and P3 may be different. For example, P3 may be greater than P1. This means that the scan rate for the inactive area IA may decrease when the time point t1 has elapsed. That is, it means that the interval between displaying images in the inactive area IA can be increased. Ideally, stopping scanning for the inactive area (IA) can save the most resources. However, when scanning is stopped, the color of the inactive area IA may not be expressed as pure black. Accordingly, it is possible to save resources of the entire mobile terminal 100 by lowering the scan rate for the inactive area IA within the limit of maintaining pure black.

P1 and P2 may be different. For example, P2 may be greater than P1. That is, when the time point t1 elapses, it means that the scan rate for the active area A may be lowered. The activation area A may be an area where minimal information such as a clock is displayed. Accordingly, an image to be displayed in the active area A may be a static image rather than a dynamic image. Therefore, even when the scan rate is lowered to a certain extent, the quality of the image to be displayed in the active area A may be undetectable by the user.

P1 and P2 may be the same. That is, there may be no change in scan rate before and after the time point t1 in the active region A. Even when P1 and P2 are the same, since P3 is greater than P1, resource consumption of the entire mobile terminal 100 may be less than before time t1.

26 to 28 are diagrams illustrating operations of a mobile terminal according to an embodiment of the present invention.

As shown in these drawings, the mobile terminal 100 according to an embodiment of the present invention can reduce resource consumption by minimizing the operation of the control unit 180 after a specific point in time.

As shown in FIG. 26 , in a general case, even if the controller 180 enters a mode in which only a part of the display 151 is activated, it may need to be activated at regular intervals. For example, at time t1, the mobile terminal 100 may activate only a part of the display 151 to enter a mode for displaying minimal information.

Even when entering a mode in which only a part of the display 151 is activated, it may be necessary to display an image in the active area A for each specific time point. For example, in the case of displaying a clock on the active area, this means that the image displayed on the active area A should be changed every minute (t2, t3, t4, t5, t6) when the minute display is changed.

Activation of the controller 180 may be related to a frame buffer state showing the state of data to be displayed on the display 151 . For example, it means that the control unit 180 can be activated correspondingly to input and/or output data to the frame buffer.

When the controller 180 is activated, resources of the mobile terminal 100 including power consumption may be consumed. The mobile terminal 100 according to an embodiment of the present invention can minimize resource consumption by minimizing activation of the control unit 180 .

As shown in FIG. 27 , the controller 180 may control the overall operation of the mobile terminal 100 . For example, it means that the memory 170 and/or the touch controller 210 can be controlled.

The touch controller 210 may be configured separately from the control unit 180, which is the main controller. The touch controller 210 may be a display drive IC (display drive IC). That is, it means that it can be configured physically separately from the control unit 180. The touch controller 210 may operate based on a control signal from the control unit 180, which is a main controller. The touch controller 210 may operate separately from the controller 180 in a state of displaying an active area. For example, the controller 180 means that the touch controller 210 can display an image in the active area A in a deactivated state.

The touch controller 210 may include a touch memory 222 . Minimum data to be displayed in the active area A may be stored in the touch memory 222 . For example, this means that data capable of displaying changes in hours, minutes, and seconds may be stored.

When displaying the active area A for the first time, the touch controller 210 may receive part of data to be displayed on the active area A from the external memory 170 . The data received from the memory 170 and the data of the touch memory 222 are sent to the frame buffer 224 so that the corresponding image can be displayed on the display 151 .

After entering a mode for activating only a part of the display 151 and obtaining a necessary image, it may not be necessary to obtain an additional control signal from the controller 180 . That is, after entering a mode in which only a part of the display 151 is activated, the controller 180 may enter a sleep state and maintain the sleep state.

The touch controller 210 may acquire data necessary for displaying changes in the active area A from the touch memory 222 even when the controller 180 maintains a sleep state. For example, this means that a minimum image necessary for changing the hour, minute, second, etc. may be stored in the touch memory 222 . An image obtained from the touch memory 222 may be displayed on the display 151 through the frame buffer 224 .

As shown in (a) of FIG. 28 , the state of the control unit 180 may be changed after time t1. For example, it means that it can change from an active state to a sleep state. The control unit 180 of the mobile terminal 100 according to an embodiment of the present invention may not need to repeatedly change the state to the active state after changing to the sleep state. That is, since the operation required to display the active area A after the time point t1 is performed by the touch controller 210, the operation of the controller 180 may not be required.

As shown in (b) of FIG. 28 , the touch controller 210 may be selectively activated at a certain time point after time t1. For example, when a clock is displayed in the activation area A, it means that it can be activated every minute (t2, t3, t4, t5, t6) to change the minutes of the clock.

As shown in (c) of FIG. 28, the frame buffer 224 may be filled with data received from the touch controller 210 in a certain unit. For example, this means that the frame buffer 224 can be filled with image data for displaying changes in the active area A.
