The case 200 forming the exterior of the roll-slide mobile terminal 100 includes a first frame 210 and a second frame 220 . The second frame 220 is slidable in a first direction with respect to the first frame 210 . Of course, since the movement of the first frame 210 and the second frame 220 is relative, the fixed member and the sliding member may be described in reverse.

In this embodiment, among the first frame 210 and the second frame 220 , the first frame 210 forms the main exterior area, and the second frame 220 is drawn out from within the first frame 210 . assumed to come out. Accordingly, the main electric part may be formed in the first frame 210 .

Among the front areas 151F of the display unit 151 , an area continuously maintained regardless of expansion or reduction is defined as a fixed area 151U, and an area selectively exposed on the front surface according to expansion or reduction is defined as a variable area 151X. Since the winding region 151C variably moves on the variable region 151X and divides the front region 151F and the rear region 151R, the variable region 151X may be included in the front region 151F or the rear region in some cases. (151R) may be included.

The fixed area 151U of the front area 151F of the display unit 151 may be fixed to the first frame 210 or the second frame 220 .

In this embodiment, it is assumed that the fixing area 151U is fixed to the second frame 220 . That is, when the second frame 220 slides in the first direction with reference to FIG. 2 , the fixed area 151U of the display unit 151 fixed to the second frame 220 also moves, and the winding area 151C. moves in a direction opposite to the first direction. However, as described above, the opposite case is also possible.

When the second frame 220 slides in the first direction and extends from the first frame 210 , the front area 151F of the display unit 151 is also expanded so that the fixed area 151U and the variable area 151X are formed on the front surface. is exposed, and when the second frame 220 is reduced in the first frame 210 by sliding in the opposite direction to the first direction, the front area 151F of the display unit 151 is also reduced, so that only the fixed area 151U is reduced. will remain

The rear cover serves to maximally cover and protect a flexible structure in which the display unit 151 moves on the rear surface of the second frame 220 .

Meanwhile, the front area 151F of the display unit 151 may be exposed to the front without a separate window. The edge cover 211 covers the boundary area between the front area 151F of the display unit 151 and the first frame 210 to prevent the inflow of foreign substances, and the deco frame 201 is the mobile terminal 100 and the display unit 151 ) can help the user's screen visibility by covering the non-output bezel area.

The edge cover 211 covers the winding area 151C of the display unit 151 . The edge cover 211 can guide the display unit 151 to be well bent by pressing the winding area 151C from the outer surface of the display unit 151, and can close the gap between the display unit 151 and the case. It prevents the display unit 151 from being separated from the case or damaged by external force by filling or covering it.

Electronic components for driving the roll-slide mobile terminal 100 such as the battery 191 and the like may be formed in the inner space formed by the exterior structure of the first frame 210 and the second frame 220, etc. It may be mounted on the main board (main-PCB, 181) to be provided in the electrical unit. Alternatively, an electronic component such as an internal antenna module may be provided directly on the electric part without passing through the main board 181 .

The fixing area 151U of the display unit 151 may be fixed in close contact with the case 200 . For example, an adhesive may be applied to the rear surface of the edge region 1511 of the fixing region 151U to be seated and coupled to a corresponding region of the case 200 . The corresponding area of the case 200 may be the above-described decor frame 201 .

On the other hand, the variable region 151X of the display unit 151 cannot be completely coupled to the case 200 unlike the fixed region 151U. Accordingly, a gap is generated between the variable region 151X of the display unit 151 and the case 200 , and there is a risk that foreign substances such as dust may be introduced into the space or be caught in the gap.

In addition, as described above, the edge cover 211 for covering the winding area 151C may be coupled to the case, but it is practically impossible for the edge cover 211 to completely seal the winding area 151C, and the winding area ( Since the 151C is variable, the edge cover 211 and the display unit 151 cannot be attached and fixed. Therefore, a gap is inevitably generated between the display unit 151 and the edge cover 211 .

The inflow of foreign substances through the gap or the trapping of foreign substances may cause malfunction of the device, damage the display unit 151, impair the aesthetics, and reduce the user's tactile sense.

FIG. 5 conceptually illustrates one principle of moving and removing the foreign material 401 on the surface of the display unit 151 related to the present invention.

As a method to prevent the inflow or trapping of the foreign material 401 , there is a method to shake off the foreign material 401 by generating regular vibrations in the display unit 151 .

Vibration generated in the display unit 151, particularly vibration due to a standing wave, may be in a direction perpendicular to the output surface 1513 of the display unit 151 outward, and the foreign material 401 may be cracked according to the vibration. The foreign material 401 moves in a direction in which the output surface 1513 of the display unit 151 is inclined by the resultant force of the force in the pinching direction and gravity. If this process is repeated, the foreign material 401 moves toward the inclined end of the output surface 1513 of the display unit 151 and falls off. Hereinafter, the foreign material 401 and the dust are mixed without distinction.

The method of brushing off the foreign material 401 by vibration can be more usefully used not only when the output surface 1513 of the display unit 151 is exposed to the outside of the mobile terminal 100 but also when it is not exposed to the outside. . For example, when the rear area 151R of the display unit 151 is covered by a configuration such as a cover window spaced apart from the display unit 151 and the user cannot directly shake off the foreign material, the foreign material 401 is A method of wiping off may be useful. Therefore, this method can be more usefully utilized when the front area 151F of the display unit 151 is covered by a cover window spaced apart from the display unit 151 or when the above-described edge cover 211 is provided. there is.

6 is a cross-sectional conceptual view of the display unit 151 and the conductive layer 310 related to the present invention. In order to generate vibration in the display unit 151 , the mobile terminal 100 may include a conductive layer 310 . The conductive layer 310 generates a physical vibration by forming a wave 313 by conduction. As an example of a representative conductive layer 310 , there is an indium tin oxide (ITO).

When the vibration generated as the conductive layer 310 conducts is transmitted to the display unit 151 , the display unit 151 also vibrates and foreign substances may fall.

The conductive layer 310 may be provided on the rear surface of the display unit 151 , that is, at the rear of the display unit 151 based on the thickness direction of the mobile terminal 100 . This is to minimize the possibility of interference with the touch panel 1512 provided on the outer surface of the display unit 151 on the front surface of the display unit 151 , that is, on the mobile terminal 100 .

6 illustrates a case in which the display unit 151 is a POLED type as an example, but it may be applied to various output methods such as GOLED.

The conductive layer comprises a layer of indium tin oxide (ITO), also called a transparent electrode.

The conductive layer can be implemented in the form of a layer capable of performing a similar function in addition to the transparent electrode. Components that can replace the transparent electrode are metal mesh, silver nanowire, carbon nanotube (CNT), graphene, conductive polymer, fluorine tin oxide (FTO) There is this.

The metal mesh may be formed by making a grid pattern on a film and applying a metal, such as silver or copper, having a low resistance value, to the film finely like a mesh, and then printing electrodes therein. The metal mesh has the advantage of having a low surface resistance value, a fast touch response speed, being bendable, and a simple manufacturing process.

Silver nanowires can be manufactured by growing nano-sized silver (Ag) on a substrate in the form of an elongated wire using a chemical method such as a redox reaction.

7 is a conceptual diagram of a circuit configuration of the conductive layer 310 related to the present invention.

The conductive layer 310 may include a plurality of conductive lines 312 corresponding to a plurality of regions of the output surface 1513 of the display unit 151 . The plurality of conductive lines 312 may form a pattern by forming a predetermined rule.

The conductive layer 310 may be provided in the form of a plurality of conductive lines 312 provided on the front or rear surface of the glass substrate 311 . The plurality of conductive lines 312 may be formed on the glass substrate 311 by a patterning method. The conductive layer 310 is provided on the rear surface of the display unit 151 , and in particular, may be attached to and fixed to the rear surface of the display unit 151 .

The reason for individually implementing the plurality of conductive lines 312 corresponding to the plurality of regions is to independently drive each of the conductive lines 312 so that the plurality of regions independently vibrate. That is, the plurality of regions of the output surface 1513 of the display unit 151 may obtain a desired pattern of vibration. In other words, the conductive layer 310 provided with the plurality of conductive lines 312 functions as an electric field to affect the display unit 151 .

For independent driving, a plurality of conductive lines 312 are individually connected to a circuit that forms a potential difference. The processor 180 may control each conductive line 312 to be individually conductive.

The processor 180 may implement a desired shape of the wave 313 by applying a current to at least one of the plurality of conductive lines 312 .

The plurality of conductive lines 312 may be formed of a plurality of parallel straight lines. In this case, the straight line means a substantially straight line, and does not need to be physically completely straight.

Alternatively, the plurality of conductive lines 312 may be formed of a plurality of curved lines having a similar directionality.

The wave 313 by the plurality of conductive lines 312 may form various patterns. Representatively, the plurality of conductive lines 312 may form a traveling wave traveling in one direction, or a standing wave that appears to vibrate in place by varying the amplitude of the wave 313 excluding nodes may be formed. The traveling direction of the traveling wave may be a direction perpendicular to the plurality of conductive lines 312 . The foreign material 401 may move according to the direction of the traveling wave.

In particular, the traveling wave may be usefully applied when the display unit 151 is parallel to the ground, that is, perpendicular to the direction of gravity. The standing wave may be particularly usefully applied when the display unit 151 forms an inclination with respect to the ground.

In order to move and shake off the foreign material 401 in a state in which the display unit 151 is parallel to the ground or forms an angle of 20 to 30 degrees with the ground, a traveling wave is preferable. It is preferable that the traveling waves have at least three phases having phase differences from each other. A three-phase phase may be defined as applied to three consecutive conductive lines 312 .

On the other hand, when the display unit 151 is tilted with respect to the ground, that is, when the foreign material 401 is moved and shaken off in a state where the display unit 151 forms an angle exceeding 20 to 30 degrees with the ground, a standing wave or an inclined A traveling wave traveling in the true direction is preferable. The standing wave may be implemented as a sum of two-phase waves 313 moving in opposite directions.

The plurality of conductive lines 312 provided in parallel may be disposed at intervals in a predetermined direction. This constant direction is defined as a second direction. A set of conductive lines 312 disposed at intervals in the second direction is defined as a first group of conductive lines 3121 . The conductive layer 310 may have only the first group of conductive lines 3121 , or it may have an additional set of conductive lines 312 .

The second direction may be formed in the same manner as the first direction, and may be a portrait, that is, a horizontal direction with respect to the front surface of the mobile terminal 100 in the portrait mode. This is useful when the mobile terminal 100 is often used in a landscape, that is, in a landscape mode.

Alternatively, the second direction may be formed perpendicular to the first direction to be a vertical direction with respect to the front surface of the mobile terminal 100 in the portrait state. This is useful when the mobile terminal 100 is often used in a portrait state.

Alternatively, in some cases, the second direction may be formed to form a 45 degree angle with the first direction. This allows the mobile terminal 100 to exert an appropriate effect in both a portrait or a landscape state.

In the case of a traveling wave, the plurality of conductive lines 312 may be sequentially conductive along the second direction or sequentially conductive along a third direction opposite to the second direction. That the plurality of conductive lines 312 are sequentially conductive means that the plurality of conductive lines 312 have sequential phases.

8 and 9 illustrate several embodiments of a plurality of conductive lines 312 according to the present invention.

The plurality of conductive lines 312 may form at least two groups of the plurality of conductive lines 312 , which are not all oriented in one direction as described above, but are oriented in different directions. For classification, a plurality of conductive lines 312 forming gaps in the second direction are defined as a first group of conductive lines 3121 .

The plurality of conductive lines 312 may include a second group of conductive lines 3122 separated from the first group of conductive lines 3121 . The second group of conductive lines 3122 form a gap in another direction. The characteristics of the second group of conductive lines 3122 may correspond to the description of the first group of conductive lines 3121 .

In particular, the second group of conductive lines 3122 may be perpendicular to the first group of conductive lines 3121 . When the conductive line 3121 of the first group and the conductive line 3122 of the second group form mutually perpendicular to each other, the processor 180 can selectively use the conductive line 312 of the group necessary for the situation. It is useful, and it can form traveling waves in all four directions with a phase of 90 degrees, so it can cover most situations.

8 illustrates a state in which the conductive lines 3121 of the first group are parallel to the first direction, and FIG. 9 illustrates a state in which the conductive lines 3121 of the first group are inclined at 45 degrees to the first direction.

The above-described properties of the pattern of the first group of conductive lines 3121 or the pattern of the plurality of conductive lines 312 formed of a plurality of groups may be applied to all embodiments to be described later.

10 and 11 are conceptual views of the display unit 151 and the conductive layer 310 related to the present invention.

The spacing of the plurality of conductive lines 312 may be uniform for all conductive lines 312 . In this case, the optimal spacing may be determined in consideration of power consumption, a typical size, weight, and viscosity of foreign substances.

On the other hand, an interval between the plurality of conductive lines 312 may vary according to an area of the display unit 151 . For example, the distance between the plurality of conductive lines 312 may be equal to or narrower as they approach the winding area 151C.

For example, two regions divided as shown in FIG. 10 may form a plurality of conductive lines 312 having different intervals, and as shown in FIG. 11 , as shown in FIG. 11 , the region may have a gradually narrower interval as it approaches a specific point or region. may be

More specifically, referring to FIG. 10 , the plurality of conductive lines 312 are provided at first intervals in the fixed region 151U, and the plurality of conductive lines 312 are provided at second intervals in the variable region 151X. provided, the first interval may be greater than the second interval. As described above, since the variable region 151X is a direct region in which foreign substances are introduced or caught, a plurality of narrower conductive lines 312 may be formed in this region to minimize the possibility of foreign substances being introduced or caught.

Referring to FIG. 11 , the spacing between the plurality of conductive lines 312 may become narrower as the winding area 151C approaches. In this case, the narrowest point may be the axis C corresponding to the winding area 151C in a state before the second frame is drawn out. Alternatively, as the variable region 151X including the winding region 151C approaches, the distance between the plurality of conductive lines 312 may gradually become narrower.

Hereinafter, embodiments in consideration of the inclination of the display unit 151 of the roll-slide mobile terminal 100 are related.

The processor 180 may maximize the efficiency of removing foreign substances by performing different controls according to the inclination of the display unit 151 , that is, the orientation of the mobile terminal 100 .

The mobile terminal 100 may include a gyro sensor for measuring the orientation.

12 illustrates four situations in which the inclination of the front area 151F of the display unit 151 is different from each other.

For convenience of description, only the case in which the plurality of conductive lines 312 are disposed in the form shown in FIG. 8 will be described.

In the processor 180 , the conductive line 312 may sequentially conduct, that is, a traveling wave in a direction closest to the direction in which the display unit 151 is inclined.

The conductive lines 3121 of the first group may be sequentially conductive in the second direction or the third direction, and the conductive lines 3122 of the second group are opposite to the fourth direction or the fourth direction that is above the output surface 1513 . A traveling wave may be formed by sequentially conducting in a fifth direction, which is a direction.

In consideration of the direction of gravity and the gradient of the mobile terminal 100 measured by the gyro sensor, the processor 180 causes the conductive lines 312 of the group corresponding to the direction forming the smallest angle with the direction of gravity to sequentially conduct in the corresponding direction. can

For example, in the state of FIG. 12(a), the processor 180 sequentially conducts the conductive lines 3122 of the second group to be sequentially conducted in the fifth direction, and in the state of FIG. 12(b), the processor 180 180 may cause the first group of conductive lines 3121 to be sequentially conductive while being sequentially conductive in a left direction (ie, a third direction).

However, when the inclination of the mobile terminal 100 is formed so that the edge cover 211 is downward as shown in FIG. 12C , the processor 180 may stop the conduction of the plurality of conductive lines 312 . This is because, in the vicinity of the edge cover 211 , foreign substances may be introduced or caught in the gap between the display unit 151 and the case of the variable region 151X or between the edge cover 211 and the display unit 151 . In addition, since sequential conduction in the opposite direction or generation of standing waves may have an adverse effect, it is desirable not to conduct the conduction at all.

In the case of FIGS. 12( a ) to 12 ( c ), foreign substances may be shaken off by generating a standing wave acting only with a force perpendicular to the output surface 1513 as well as the aforementioned traveling wave (see FIG. 5 ).

On the other hand, when the output surface 1513 of the mobile terminal 100 corresponds to a state perpendicular to the direction of gravity as shown in FIG. 12( d ), the processor 180 performs the first group of conductive lines 3121 or the second group. may sequentially conduct the conductive line 3122 in the third direction, the fourth direction, or the fifth direction. At this time, it is preferable not to conduct sequentially about the 2nd direction. This is the same as the basis for the case of Fig. 12(c) described above.

13 is a cross-sectional view of the roll-slide mobile terminal 100 according to the present invention.

The edge cover 211 has both sides 2111 in the width direction substantially in contact with the outer surface of the display unit 151 (that is, forming a fine gap), and the inner side is spaced apart from the outer surface of the display unit 151 by a certain distance. can form. Both sides 2111 of the edge cover 211 prevent foreign substances from entering the inside, but foreign substances may be introduced or caught in the minute gaps.

In particular, foreign substances introduced through both sides 2111 of the edge cover 211 may scratch the display unit 151 while traversing the inner space 213 or flow into the case through the upper and lower ends of the edge cover 211 in the longitudinal direction. could be

To solve this, an adsorption surface 212 may be provided on the inner surface of the edge cover 211 . The dust adsorption surface 212 has an adhesive force such as rubber or silicone material to prevent the introduced foreign substances from flowing. The adsorption surface 212 may be attached to the inner surface of the edge cover 211 as a separate member or may be formed by double injection, or the entire material of the edge cover 211 may be formed of the same material as the adsorption surface 212 . may be

The edge cover 211 may be provided to be detachably coupled from the case. The edge cover 211 can be removed from the case to remove the adsorbed foreign substances, and can be used by reconnecting.

When the edge cover 211 is removed, there is an advantage that foreign substances in the winding area 151C of the display unit 151 can be wiped off.

14 illustrates an embodiment of a conductive line 312 pattern of a winding region 151C related to the present invention.

A conductive line 312 pattern may be provided to discharge foreign substances introduced into the inner space 213 of the edge cover 211 . For example, the plurality of conductive lines 312 may be spaced apart from each other in the longitudinal direction of the winding region 151C. A set of the plurality of conductive lines 312 of this pattern is defined as a third group of conductive lines 312 .

When the plurality of conductive lines 312 are spaced apart in the width direction of the winding region 151C, foreign substances introduced into the inner space 213 are continuously moved to at least one side of both sides 2111 of the edge cover 211. This can cause jamming problems, etc. Therefore, it is possible to take a method of moving the foreign material introduced into the inner space 213 in the longitudinal direction of the edge cover 211 and removing it from the longitudinal end of the edge cover 211 .

Furthermore, the third group of conductive lines 312 may be provided in a region before the second frame is expanded.

Alternatively, since the winding area 151C corresponding to the area of the edge cover 211 varies on the variable area 151X, the third group of conductive lines 312 may be provided across the variable area 151X.

In addition, the area of the display unit 151 excluding the area in which the third group of conductive lines 312 is provided, that is, the fixed area 151U, may not include the conductive lines 312 or implement the same pattern as described above. Conductive lines 312 such as examples may be provided.

The above detailed description should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.

The above-described features can be wholly or partially applied to a roll-slide type mobile terminal, other types of mobile terminals, and devices having a display unit.
