As shown in the figure, a support spring 81c is provided on the rear side of the movable support plate 81b, and a support groove 81d on which the support spring 81c is mounted. In the figure, a round circle represents the fixing projection 76a. .

However, at this time, the moving support plate 81b may be pushed in the direction of the arrow. This is to give an error range that can adjust the degree of close contact between the two panel housings 20 and 40 to be more resistant to impact.

FIG. 22 is a diagram illustrating an error method when two panel housings 20 and 40 are unfolded.

The two panel housings are in close contact with each other, while the top view is shown slightly below.

In addition, if the value of the degree that the two panel housings can fall to the maximum α, it is preferable that the α value does not exceed 1.5mm-2mm. This is because if the value of α is too large, the seam between the displays becomes too large.

Example 3

-In practice 5-

30 is a view showing a panel housing having a protective cover removed.

As shown in the figure, the side of the display 2 and 4 is mounted close to the panel housing side wall 20a.

The side wall 20a shown in the figure is a portion where the display is adjacent to each other. In the figure, the side of the display 2 is shown in an exposed state, but it is obvious that the side of the display may be blocked by a protective means or by the side walls of the panel housings 20 and 40.

31 is an enlarged view of a seam of a display.

In the present invention, the two screens are connected to minimize the seam, so the display should be designed to reduce the seam.

When there is a pixel 2n closest to the seam 8 as shown in the drawing, the distance J between the adjacent pixel 2n and the partition wall 2f is within 1 mm, and in the closest case, within 0.01 mm.

The thickness K of the partition wall 2f is also set to 1 mm or less and at least 0.01 mm or more. Therefore, the distance between the pixel 2n closest to the seam and the edge boundary of the display 2 and 4 is within a minimum of 0.02 mm or more and within 2 mm.

In addition, the thickness of the chassis 16 shall not exceed 0.1 mm or more and 1 mm or less. However, the maximum thickness of the most efficient chassis 16 does not exceed 0.5 mm. Of course, the chassis 16 may be open to the seam, in which case the thickness of the chassis 16 at the seam is 0 mm.

Of course, the boundary between the boundary line 2g of the display panel and the partition wall 2f does not need to be completely coincident with the seam 8, and it is natural that the partition wall 2f may be provided within 0.5 mm from the boundary line 2g. .

32 is an enlarged view of an input device and is an enlarged view of a portion B of FIG. 5.

An input device may be mounted on the top of the display (2) (4) of the present invention, two input devices also one input device 250 when all the input device is mounted on the top of each display (2) (4) You need to change the design to make it look like you use.

In general, an input device is mounted on an upper portion of a display to serve to input or select information.

That is, in the input device, a lead wire reading a capacitance value or a resistance value is provided on the side of the input device. At this time, the position of the lead wire 250n in the joint portion must be changed. And, sometimes the partition 250f may exist.

The distance M between the lead wire 250n and the partition wall in the joint 8 is at least 1 mm, and the thickness L of the partition wall 250f is also at most 1 mm.

Of course, the boundary 250g of the input device and the boundary of the barrier 250f do not need to be completely coincident with the joint 8, and the barrier 250f may be provided within a range of 0.5 mm from the boundary 250g. Of course.

On the other hand, the partition wall does not necessarily need to exist depending on the input device method such as the capacitance method.

In addition, 250a represents an information input unit of the input device, and its structure differs depending on the resistive film type and the capacitance type.

33 illustrates a case in which an input device is mounted on the top of the display.

The joint part 8 includes a third support part 26c to support the display 2, and the display 2 supports the input device 250.

34 illustrates a case where the input device and the display are separated.

A fourth support part 26d is further provided on the side wall of the panel housing 20 to support the input device 250.

At this time, the third supporting portion and the fourth supporting portion 26d are present in the non-display area of the joint portion 8. On the other hand, when the upper surface of the display is covered with the chassis (indicated by 16-1 and 16-2 in the drawing), the opposite side of the joint is thicker than the joint side, and the screen non-display area is in principle.

Then, when "V1" protects the side of the display 2 at the joint portion 8 and "V2" protects the side of the input device 250, "V1" and "V2" extend the side wall 20a. It may be formed as a part, but may be configured separately, and the material may be a plastic resin or a metal alloy.

Also, the thickness of "V1" does not need to be the same as the thickness of "V2", and in some cases, "V1" may be thin or thick or thin.

The thickness of " V1 " may be thin as 0.001 mm to have a sealing coating film shape, but the thickness of about 1.5 mm can also function as a protective side wall. Similarly, although the thickness of "V1" may be thin as 0.001mm and may have the form of a sealing film, the protective side wall may function as a thickness of about 1.5mm.

Meanwhile, when the displays 20 and 40 are unfolded, the distance between the two displays 20 and 40 is within 3 mm, and the distance between the two input devices is also within 3 mm.

Thus, even if the thickness of the V1 is 1mm, the distance between the two displays and the distance between the two input devices may be 3mm.

Example 6

35 to 37 are diagrams of embodiments in which the shape of the protective cover is changed.

The upper panel housing 20 has a structure in which both edges are made longer by “S.” Thus, the length of the protective cover 43 provided in the lower panel housing 40 is shortened. May be formed equal to or shorter than the width of the protective cover 43.

In the figure, 35 is a view showing a state in which the upper and lower panel housings 20 and 40 are stacked. As shown in FIG. In addition, the two panel housings are fully extended as shown in FIG. 37.

38 and 39 are views illustrating the lower panel housing.

The projection plate 76 is formed in a “c” shape and extends further in both edge directions. Therefore, the position of the fixing protrusion 76a is also moved inward.

On the other hand, the lower cover 43a is further extended in both edges to have a 'c' shape, and the protrusions 76 can be moved out of the panel housing boundary.

And the position of the spring protrusion 307b and the insertion hole 307a by the dotted line in the side plate 307 is shown.

The spring protrusion 307b is coupled to the side plate 307 by means such as a hinge or a screw nail. Further, a curved housing 308 surrounding the spring protrusion 307b and the insertion hole 307a is further provided, and the curved housing 308 is coupled to the side plate 307 by a coupling plate 308a. The coupling plate 308a is coupled through a coupling portion 308b such as a screw or a hinge nail.

In addition, the spring protrusion 307b has a curved shape and is made of a metal body or plastic having elasticity, such as a spring, and may be slightly changed in shape by an applied force or pressure.

45 is a view showing the engaging projection of the lower panel housing.

As shown in the figure, a coupling protrusion 97 and a protrusion head 97a are provided at a side surface of the lower panel housing 40, and the coupling protrusion 97 is inserted into an insertion hole 307a of the side plate 307. 97a is positioned between the spring protrusion 307b and the curved housing 308.

46 is a principle diagram in which the panel housing moves by the projection head.

In the present invention, the spring protrusion 307b has a curved shape as shown in the drawing, but is made of a metal or plastic material having elasticity. In addition, the projection head 97a is positioned between the spring protrusion 307b and the curved housing 308 so that the protrusion head 97a moves up and down along the curved shape.

In addition, the upper panel housing 20 and the lower panel housing 40 move upward and downward in a curve by the movement of the projection head 97a.

On the other hand, the engaging projection 97 is also connected to the inside of the side wall of the lower panel housing 40, the spring device 97b is wrapped as shown. A jaw 97c is also provided to prevent the engaging projection 97 from escaping the side wall of the lower panel housing 40.

And, because of the spring device (97b) the projection head (97a) is able to move the surface of the spring projection (307b) of the curved shape.

47 to 49 are views illustrating a principle in which the upper panel housing and the lower panel housing move in the left and right directions and in the up and down directions.

The bottom plate 330 is provided on the bottom surface of the upper panel housing 20, and the sliding groove 80 so that the sliding protrusion 332 of the bottom plate 330 can be inserted into the guide groove 314b of the plate 310. Is provided. Although the groove is not shown in FIG. 31 for convenience, the groove 80 of FIG. 5 of the present invention may be referred to.

In addition, a plate 310 is provided below the bottom plate 330, and a spring assembly 320 is provided between the bottom plate 330 and the plate 310. In addition, the support plate 300 is provided below the plate 310, and similarly, another spring assembly 325 is provided between the plate 310 and the support plate 300.

At this time, the support plate 300 is provided to be firmly fixed to the top of the support portion (43a) of the lower panel housing (40).

In the state in which the upper panel housing 20 and the lower panel housing 40 are overlapped and completely closed as shown in FIG. 47, the applied force is the state in which the pulley spring assemblies 320 and 325 are restored.

48 shows the spring assembly 320, 325 compressed or inflated with a force applied thereto.

On the other hand, when the sliding movement in the left and right direction is finished by pushing the upper panel housing 20 as far as possible, the upper panel housing 20 is moved in the vertical direction. (In Fig. 49) In this case, the projection head 97a is a spring projection ( Moving between 307b and curved housing 308.

50 is a view showing a cross-sectional shape of the bottom plate.

As shown in the figure, the bottom plate 330 is mounted directly to the bottom of the upper panel housing 20. Therefore, the bottom plate 330 is made of a material such as metal. In addition, sliding protrusions 332 are formed at both ends of the bottom plate 330, and the bottom grooves 80 are made to be movable by inserting the sliding protrusion 332 and the fixing groove 311 of the plate 310.

51 and 52 are views showing the principle of the path that the panel housing moves through the spring projection.

When the upper panel housing 20 and the lower panel housing 40 moves up and down, the linear panel moves in a curved motion, not linear movement. As a result, the mutual distance between the upper panel housing 20 and the lower panel housing 40 moves up and down. It will be spaced apart and then pressed again.

At this time, the distance to be separated is not good too large and usually 0.5mm is suitable, but may be from 1mm to 3mm.

51 illustrates a spring protrusion 307b having a protruding curved shape, and thus the upper panel housing 20 and the lower panel housing 40 also move in the opposite direction.

That is, when the upper panel housing 20 moves below the lower panel housing 40, the upper panel housing 20 rises higher than the lower panel housing 40 and moves downward. Then, as a result, the upper panel housing and the lower panel housing come into close contact with each other at the same height.

At this time, the distance to go up is usually about 0.5mm is enough, but within 3mm may be appropriate.

Conversely, when the lower panel housing 20 returns to its original position, it moves along the opposite path.

On the other hand, as shown in the drawing, the protrusion 307d can be taken as a design structure that is easily contracted by adding a separate spring device.

53 is a view illustrating movement of the upper and lower panel housings.

When the upper and lower panel housings 20 and 40 move in the sliding direction ((A) state in the drawing), the upper and lower panel housings 20 and 40 become a state before moving up and down (B) in the drawing.

Further, applying a further moving pressure causes the upper panel housing 20 to rise slightly above the lower panel housing 40 ((C) state in the drawing). About 3 mm is suitable, and the distance is determined by the size of the projection 307d in FIG.

The upper panel housing 20 is slightly raised upward and then moved downwardly ((D) in the drawing). The upper panel housing 20 and the lower panel housing 40 are moved slightly apart even when moved downward. do. At this time, there is a suitable separation distance and may be very small as 0.05 mm, but 0.5 to 3 mm is suitable.

Then, through the above process, the display is adjacent to each other (the state (E) in the drawing).

Example 8

54-57 show an embodiment of a spring assembly.

In the present invention, it is possible to use a conventional spring composite that can be compressed or expanded when the force is applied, and then restored again when the force is released. However, the present invention is not a spring composite invention, any spring or object that can be restored after compression or expansion can be used.

54 shows that two sliding bars 320b and 320c coupled to the coil spring 320a are mutually slid by the sliding means 320d, wherein the two sliding bars 320b and 320c are moved by the coil spring 320a. ) Allows mutual compression and expansion.

55 is a principle that allows the plate 310 to move using the inclined bar 327a and the compression spring 327. That is, when the pressure is applied to the plate 310 and pushed upward, the compression spring 327 is compressed by the inclined bar 327a. When the pressure is released, the compression spring 327 is expanded to expand the plate 310 by the sliding groove or the sliding bar. Through 335 is restored to the original position.

Figure 56 is a spring assembly that allows for compression and expansion by connecting a plurality of spring in the form of a wire having a semi-circular shape. That is, a plurality of semicircular wire springs 329b are connected to each other by a rotation hinge 329c to form a rotatable joint, and then, the fixing parts 329a and 329d are placed at both ends.

Fig. 57 is a view showing an embodiment of a spring composite having one semi-circle shape, which is used when the moving distance is relatively large.

Example 9

58 to 65 are diagrams of yet another embodiment of the sliding structure.

58 to 61 are views showing the sliding movement principle.

The spring composite 320 connected to the plate 310 is connected to the bottom plate (see FIGS. 5 and 20) of the upper panel housing 20, and the fixing groove 311-1 and the guide frame (314 of FIG. 40) therein. Is omitted for convenience) is connected to the sliding projection (332 of Figure 40) of the bottom plate of the upper panel housing (20).

That is, the plate 310 supports the upper panel housing 20 and causes the upper panel housing 20 to slide.

In addition, the supporting plate 340 is further provided, and the supporting plate 340 and the plate 310 may move together as an integral part. In other words, when viewed in cross-sectional shape, it is connected through a connecting body 23c-1 in a "c" shape.

The shape of the support plate 340 may be deformed by applying the function of the protrusion plate (76 of FIG. 14) shown in the previous embodiment.

The supporting plate 340 is mounted inside the lower panel housing 40, and is moved to slide from the lower panel housing so that a part of the supporting plate can come out.

At this time, the principle that the support plate 340 sliding out of the lower panel housing 40 can also be applied to the principle that the plate 310 and the spring composite 320 is moved, or a conventional guide structure and spring The device can be used.

In this case, when a part of the support plate 340 comes out of the lower panel housing, a structure capable of supporting the support plate 340 may be made, which may be referred to the foregoing embodiment.

When the user of the display device pushes the upper panel housing in the state of overlapping each other (FIG. 112), the upper panel housing 20 moves the plate 310 (FIG. 59).

Further, when pushed further, the supporting plate 340 partially comes out, and the connected plate 310 and the upper panel housing 20 come out of the boundary of the lower panel housing 40 (FIG. 60).

Then, when the user pushes the upper panel housing downward, the upper panel housing and the lower panel housing are in the same height as each other (Fig. 61).

At this time, the support plate 340 moves downward in the lower panel housing 40, and thus the plate 310 also moves downward, and thus the upper panel housing 20, which the plate 310 supports, also moves. Will come down.

At this time, the principle of the support plate 340 to move down can be implemented using the pressing side or expansion of the spring and the moving guide component.

On the other hand, when the upper and lower panel housings are in the same height, mutual coupling means or locking means exist to maintain the same height.

Then, when the coupling means or the locking means is released, the spring used to move the support plate 340 is restored so that the upper panel housing rises above the lower panel housing, and the support plate used to move in the left and right directions ( The springs of the 340 and the plate 310 are also restored so that the upper and lower panel housings are overlapped in their original state.

62 is a view showing a principle of moving in the movement of the side.

Here, the support part 43C which supports the support plate 340, and the moving means 341 which move and use the support plate 340 mutually are provided. The moving means 341 may be applied to the principle of the plate and the bottom plate to move through the spring composite or the moving method of another embodiment of the present invention.

On the other hand, when the panel housings 20 and 40 are unfolded and then moved in the vertical direction, one panel housing needs to have a thinner height in order to reduce the vertical movement distance.

Meanwhile, the size of the plate 310 and the support plate 340, which are moving hinges in the circle, is shown.

It is preferable that the width W of the plate 310 does not exceed 1/2 of the width of the display device, and the smaller the width W, the higher the design efficiency, but the less robust. Therefore, the width W should be at least 2 mm.

In addition, the inner height (T2) is preferably 0.5mm or more because the thickness of the panel housing case should be considered. However, the display 2, 4 may also be located, in which case it is considered to be about 3-5 mm.

The outer height T1 may be determined in consideration of the thickness of the plate plate at the inner height. If 0.3mm, the outer height is 0.6mm larger than the inner height. Usually, the thickness of a plate plate is suitable within 0.2 mm to 2 mm.

On the other hand, the connecting member 23c-1 may be formed so that the connecting member may cover the display side of the joint portion. The connecting side may not be formed at the display side portion, in which case the protective cover 23c may display the joint portion display. It will cover the sides.

63 shows the movement in the plane.

When the backing plate 340 moves, the plate 310 exits out of the panel housing boundary. At this time, if the exit degree is represented by the W value, the value follows the example of FIG. The backing plate 340 is located at both edges, and is located at the outer edge of the display 2, 4.

In addition, the length L of the plate is related to the length of the portable display device, and may be considered to be about 50% or more to about 99% of the total length of the portable display device.

Fig. 64 shows the arrangement of the circuit connecting lines.

A space is formed between the support plate 340 formed on both sides and the plate, and a circuit connection line 340b is provided in the space. In addition, a coating film or plate 340d may be provided to protect the circuit connection line. And the connector 340c is provided at the end.

That is, a circuit connecting line connecting the upper panel housing 20 and the components of the lower panel housing passes through the space between the support plate 340 and the plate 310.

Example 10

65 and 66 are views of the embodiment provided with the extension.

An extension portion 345 extending out of the panel housing boundary is further provided to serve to more firmly support each other in a state where the heights of the upper and lower panel housings are equal to each other.

At this time, the extension portion 345 is a structure capable of sliding movement through the spring device and the guide means (50a, 50b), etc. in both sides of the upper panel housing (20).

Example 11

67 is a view showing an example of the coupling means.

In a state where the upper panel housing and the lower panel housing are unfolded to have the same height, coupling means 55 and 55a or locking means 55 and 55a may be required to maintain the state.

In the drawings, when the upper and lower panel housings are unfolded at the same height, they are provided with protrusions or grooves at positions where the upper and lower panel housings are brought into contact with each other to have a coupling bearing force.

In this case, although FIG. 121 shows the position of the coupling means or the locking means 55 and 55a, the position may be anywhere as long as the upper panel housing and the lower panel housing are in contact with each other.

In addition, the object of the present invention can be attained by adopting a form of mutual engagement other than the structure of the groove and the projection.

Example 12

68 and 69 are views of another embodiment in which the lower panel housing is moved.

FIG. 68 is a view illustrating a principle in which two panel housings are unfolded by sliding the lower panel housing 40 in the housing 50 in the left and right directions and moving in the upper direction.

FIG. 69 is a view illustrating a principle of such a movement, and the bottom plate 81-1 is provided at the bottom of the upper panel housing, and the fixing groove 350 is moved through both side protrusions of the bottom plate 81-1. .

The support plate 351 integrally formed with the fixing groove 350 is provided with an extension support plate 352. That is, the extension support plate 352 is further moved so that the lower panel housing 40 comes out of the upper panel housing 20 boundary. The lower panel housing 40 moves upward through the spring devices 353 and 353a.

At this time, the moving means 352a is a spring composite or a guide means using a spring so that the support plate 351 and the extended support plate 352 can move left and right.

That is, when the lower panel housing 40 moves in the left and right directions, the bottom plate 81-1 and the fixing groove 350 are used. And, when the lower panel housing 40 comes out of the upper panel housing 20 boundary, the support plate 351 and the extended support plate 352 are used. Naturally, it moves through the moving means 352a between the support plate 351 and the extended support plate 352.

In addition, the spring device (353, 353a) is used when the lower panel housing 40 is moved upward.

When the panel housing is in the overlapped state, the spring is inflated or compressed, and when the panel housing is in the extended state, the spring is in the restored state.

When the two panel housings are overlapped, there must be a locking means or a coupling means to maintain the condition.

Of course, the restoration and expansion states can be reversed using the compression and expansion states of the spring, but that is generally the case for easy design structures.

Example 13

70 to 73 show examples of design variations.

A speaker 101 and a microphone 102 used for a telephone call are mounted, and a select button 100 and the like are also mounted. At this time, it is a matter of course that a separate speaker for the loud sound (position 100) can be mounted.

In addition, the length of the lower panel housing 40 is longer than that of the upper panel housing 20. do.

Meanwhile, protective covers 51 and 23 for protecting side surfaces of the joint part 8 of the display 2 and 4 are provided. The inner side surface 51a protects the side surface of the seam 8 of the upper display 2.

73 is a view showing a sliding structure.

As shown in the figure, since the sliding groove 50a has a curved shape in the joint portion 8, the panel housings 20 and 40 include curved movements when moving left and right.

The inner surface 51a and the side walls 20a and 40a of the panel housings 20 and 40 also have a curved shape.

74 to 76 are views of an embodiment in which the lower panel housing is moved.

74 illustrates a state where the upper and lower panel housings 20 and 40 overlap each other, and a handle 45 is provided on a protective cover 43 that protects the side surface of the joint 8 of the upper display 2. The handle 45 has a long projection or a long groove shape on the surface, so that it is well held in the hand.

75 is a view of a state in which the lower panel housing 40 is slid.

In addition, the sliding groove 50a formed on the inner surface of the housing 50 also has a curved shape, and includes a linear motion and a curved motion during vertical movement.

Meanwhile, although omitted in the drawings, when the display 2 and 4 are stacked up and down, the side of the seam of the lower display 4 is protected by a protective cover mounted on the housing 50 or the upper panel housing 20. Of course.

76 is a view of the display fully extended. As a result, the two displays 2 and 4 are in the same height. (Deviation within 1mm)

One panel housing 20 is a structure of an embodiment may be formed thinner.

A display 2 and an input device 200 are provided on the bottom surface of the thinly formed panel housing 20 (indicated by the arrows "0" in the figure). In the thickly formed panel housing 40, the main body part 25 is provided under the display. The main body part means a part such as a battery or a main body control unit.

Naturally, the supporting parts 26 and 46 supporting the display 2 and the like may be provided.

The thickness of the thin panel housing can vary from 25% to 70% of the thickness of the thick panel housing.

78 is a cross-sectional view when the two panel housings have similar thicknesses.

Within the panel housing the display arrangements are symmetrical to each other, but symmetrical, not even the components mounted on each panel housing.

In other words, a battery may be mounted on one of the parts 25 and 45, and a main body control part 105 may be mounted on the other parts 45.

Meanwhile, although the protective film 14 may be provided between the two displays 2 and 4, the panel housing sidewalls 20a and 40a may be provided. At this time, the thickness of the side wall of the panel protective film or the panel housing housing is preferably not more than 1.5mm.

79-81 are illustrations of embodiments with frame housings.

As shown in FIG. 79, a battery or main body circuit part is mounted on the lower panel housing 20, and a frame housing 20-1 or a bracket 20-1 is mounted on the lower panel housing 20. The display is mounted on the frame housing 20-1.

When the display 2 is mounted on the frame housing 20-1, the display 2 is mounted closer to the joint 8. That is, when a portion of the display 2 on which the screen is displayed is called an active area 2-1, the active area 2-1 is larger than the opposite side of the joint of the frame housing 20-1. It is mounted closer to the seam 8.

And the protection plate or the input device 200 is mounted on the top. The area in which information can be input from the input device 200 may be referred to as an active area 200-1, and the active area 200-1 of the input device is also seamed from the other side of the joint. Mounted closer to the unit.

In FIG. 79, the sectional view in the L-L direction is FIG. 80, and the sectional view in the K-K direction is FIG. 81. In the figure it is shown that the protective plate or the input device 200 is mounted on the frame housing 20-1. In addition, the supporting part 30-1 is mounted between the display 2 and the frame housing to support the display and absorb shock.

In the drawing, the lower part of the frame housing 20-1 may be partially cut. (As shown in FIG. 80 and FIG. 81, as indicated by D, the cutting may be possible.)

In the drawing, the panel housing 20 having a low height is directly mounted on the display 20. In addition, the supporting part 30-1 may be provided therebetween. The support part 30-1 may be provided in the whole or part of the display area.

In addition, the distance between the lower portion of the panel housing 20 and the display 2 is 2 mm or less (including 0 mm). The length H1 from the bottom of the panel housing to the protective plate or the input device 200 is also within 10 mm. However, when thinning is realized, the display can be within 1.5mm, the panel housing thickness within 1mm, and the input device including the protective plate within 1.5mm in thickness. H1 can be within 4mm and within 5mm.

In addition, the height H2 of the thicker panel housing may be within 8-12 mm or 16-25 mm depending on the situation.

 If H1 is 3-5mm and H2 is 7 15mm, the ratio of H1 / H2 is 0.20 (3/15) to 0.71 (5/7).

In addition, the display may be connected to the protection means 14, the side wall connected to the panel housing 20, 40, or the side wall connected to the frame housing 40-1.

83 to 86 illustrate a method of mounting a display.

When a part of the display 2, which is made of glass or plastic and represents a screen, is referred to as a display panel 2a, and the backlight 2b is provided on the rear surface of the display panel 2a, the OLED element has no backlight 2b. . In the drawings, the driver circuit is omitted for convenience of illustration.

At this time, when the display is mounted on the panel housing 20 or the frame housing 20-1, as shown in FIGS. 83 and 84, the display may be provided in a state where the display is mounted on the chassis or the mechanism 16.

85 and 86, when the display is mounted to the panel housing 20 or the frame housing 20-1, only the display may be mounted in a state where the chassis or the mechanism 16 is not present.

In this case, an interval between the display 2 and the panel housing 20 or the frame housing 20-1 may be 2 mm or less, and in some cases, no gap may be 0 mm. And the supporting plate (30-1) is provided between the intervals.

86 shows no backlight 2b in the case of an OLED element.

86 is shown in the figure below the arrow. That is, the function of the OLED lower substrate is the panel housing 20 or the frame housing 20-1 made of metal. You can do this instead.

By doing so, the thickness of the display device can be made thinner.

87 is a view showing the size of the fixing plate or plate.

It is a view showing that the width of the fixed plate 76 or the plate 310 is larger than the lower cover (43a) or the base plate (300). That is, W4 can be modified in a range of 1.1 times to 4 times that of W3. If the ratios differ too much, it can be difficult to place components in the design.

Example 15

88 is a diagram showing an embodiment when using as a mobile phone.

An input input keyboard 256 (type A keyboard) for inputting information can be displayed on the screen of the display 2. Although the input keypad 256 is shown as a plurality of boxes in the figure, it is a matter of course that a numeric character or the like is displayed in the box.

89 is a diagram of the embodiment when used for character input or the like.

When the two displays 2 and 4 are extended to use various contents such as data communication and information use, the input keyboard 255 (type B keyboard) may be displayed on only one screen. In this case, input of the Korean alphabet or the alphabet is possible through the input keyboard 255.

Then, when the user touches a portion where a desired letter is displayed, the input apparatus 200 or 400 may recognize the information.

On the other hand, although the input device generally has a capacitive type and a resistive film type, it is natural that the input device for inputting information on a flat plate may be used as it is.

90 is a circuit block diagram of a portable display device. The main body controller 105 includes a controller 110, a memory 120, a time controller 125, a display driver 130, an input device driver 140, and the like.

That is, each element that functions as the controller 110, the memory 120, the time controller 125, the display driver 130, and the input device driver 140 may be provided in the main body controller 105. It can be manufactured and provided as a part of.

The display driver 130 divides the screen and sends data to the first display 2 and the second display 4, respectively. In addition, the input device driver 140 also corrects and adjusts signals output from the first input device 250-1 and the second input device 250-2, respectively.

In addition, in order to display the screen of the display (2) (4), the source (2b) (4b) section for providing a data signal and the gate section (2c) (4c) for providing a line selection signal Will be present.

In addition, the sensor 135 is a sensor that promotes the positional state of the panel housing 2 and 40. In other words. It is detected whether the upper and lower panel housings 20 and 40 are stacked.

91 is a flowchart illustrating an input keyboard mode according to a sensor.

When the portable display device of the present invention is operated, it is determined whether the panel housings 20 and 40 are stacked.

When the display is selected to display the input keyboard on the screen (step 455), it is determined by the sensor 135 whether it is in a stacked state (step 460).

If the channel housing is in the stacked state, the type A keyboard is displayed on the screen (step 470). If the channel housing is not in the stacked state, the type B keyboard is displayed on the screen (step 465).

If the user selects to exit, the system is shut down (step 475).

As described above, it is possible to automatically control the state displayed on the screen according to the coupling state of the upper and lower panel housings 20 and 40.

92 is a flowchart illustrating a coupling sensor.

When the portable display device of the present invention is operated, it is determined whether the panel housings 20 and 40 are stacked by the sensor 135 shown in the block diagram.

Once stacked, the display mounted on the top panel housing is driven. A screen format for driving one display is selected (step 490). If not stacked, both displays are driven, and a screen format for driving two displays is selected. 495 steps)

The display device of the present invention can be used with only one screen and can be used with only two screens. Therefore, the screen format for displaying one screen and the screen format for displaying two screens are stored in the memory 120 of the main body controller 105 shown in the block diagram. In addition, the controller 110 selects a screen format suitable for the detection of the sensor 135.

When the screen is selected, the controller 110 controls the screen display according to the selected screen. In other words, the control mode when displaying one screen is different from the control mode when displaying two screens.

In the present invention, the sensor for detecting the stacked state refers to all sensors that are normally available, such as an optical sensor, a switch for detecting the stacked state, a proximity sensor, and the like.

Example 16

93 to 95 show an example in which the corner portion is curved.

The overlapped state (FIG. 92), the unfolded state (FIG. 93), and the display adjacent state (FIG. 94) can be expressed. And, for this purpose, the button panel 100 and the speaker 101 are provided in the upper panel housing 20, which can be used with only one display.
