11A to 11C are views showing fixing means for the side wall of the panel housing.

It is preferable that the two panel housings 20 and 40 are in an interlocked state when the panel housings 20 and 40 are opened to form a single screen while the two displays are adjacent to each other. By doing so, physical shaking can be prevented.

11A, protrusions 64 or grooves 65 are provided on the side walls of the panel housings 20 and 40. When the panel housings 20 and 40 are unfolded, the projections 64 and the grooves 65 ) Are mutually staggered.

11B, the grooves 65 and the protrusions 64 have an inclined structure such that the protrusions 64 have a narrower upper portion 64a and the grooves 65 have wider openings.

The reason for this inclined structure is to ensure that the protrusion 64 engages with the groove 65 when the groove 65 and the protrusion 64 are engaged with each other. According to the present invention, the inclined structure can be determined from the degree of inclination of 5 degrees (degrees) to the degree of 85 degrees, but it is preferable that the degree of inclination is from 30 degrees to 60 degrees.

12 is a diagram showing a display arrangement.

Quot; P "direction in Fig. 1, and Fig.

FIG. 12 is a view showing the display 2 (4) provided on the upper end of the side wall of the panel housings 20 and 40. That is, the display 2, 4 and the input device 200, 400 are provided at the top of the sidewall of the panel housing 20, 40 at the portion where the displays 2, 4 are interconnected, When the housings 20 and 40 are unfolded and brought into close contact with each other, the displays 2 and 4 are adjacent to each other and the input devices 200 and 400 are also adjacent to each other. Thus, the display devices 2 and 4 as well as the input devices 200 and 400 may be interconnected and used as a single device.

At this time, the display (2) 4 and the input device 200 (400) may directly touch each other or the side may be protected in the form of a thin protective film 14. At this time, the protective film 14 may not necessarily be a film but may be a coating film. In this case, it is natural that an opaque coating film is used. That is, the base substrate of the input devices 200 and 400 is made of tempered glass and the side of the substrate is opaque. For example, it may be black or panel housing color.

In addition, when a protective film is used, it may be coated with an inorganic material, or may be a hard coating.

At this time, the panel housing 20, which is a portion in which the panel housings 20 and 40 are in close contact with each other, so that the display 2 and the input device 4 are adjacent to each other when the panel housings 20 and 40 are unfolded, (4) and input devices (200) (400) are provided on the side upper end of the display device (40).

Various circuits and devices 25 and 45 are provided in the panel housings 20 and 40 and a pedestal 26 and 46 supporting the display 2 and 4 are also provided. A lid 24 is provided on the edge of the display 2 (4). On the other hand, the cover means 18 is not shown for the sake of simplicity.

In the various circuits and devices, one part can be a battery. That is, the battery can be positioned in one of various circuits and devices (25) and (45).

Further, an extension line of the rotation center A meets the surface of the lid 24. That is, the height of the center of rotation is the height of the cover.

Although the ends of the panel housings 20 and 40 have a curved shape in order to conform to the embodiment of the present invention, the arrangement of FIG. 12 is not limited to a curved shape, The present invention is applicable to the housings 20 and 40 as well.

It is needless to say that a protective plate, a tempered glass, or the like may be placed in place of the input device.

13 shows an embodiment in which the display and the input device are separated by the same distance.

As shown in the figure, when the portion indicated by "V" is formed into a protective film, the protective film should be as thin as possible and firm, so use a metal film or a resin film or a material in which a resin film is coated with a metal or an inorganic film Can be used.

When the portion indicated by V "is a protective film or a protective means, a metal, an alloy, a plastic or a resin is used, and the thickness is preferably 0.005 mm or more to 0.5 mm or less. In this case, the sealing effect may be more important than protecting from physical impact. The distance between the two displays (2) and (4) is at least 0.01 mm and the maximum is 1 mm. Similarly, the interval between the two input devices 200 and 400 is at least 0.01 mm and the maximum is 1 mm.

At this time, the side cover 50 described in the previous embodiment is used to protect the display 2 and the side 4 by the protection means (in order to prevent the protection function Or the side surfaces of the input devices 200 and 400 are more securely protected from physical impact.

However, the protection means (the portion indicated by V) may be formed in a plate shape from 0.2 mm or more to 1 mm or less to protect the side surfaces of the display devices 20 and 40 and the input devices 200 and 400 from physical impact You may. In this case, the distance between the two displays (2) and (4) is at least 0.4 mm and the maximum is at 2 mm. Similarly, the interval between the two input devices 200 and 400 is at least 0.4 mm and the maximum is 2 mm.

On the other hand, the portion indicated by " V " can be formed integrally with the panel housing without using any other protection means. The side walls of the panel housings 20 and 40 protect the side surfaces of the display devices 20 and 40 and the side surfaces of the input devices 200 and 400.

That is, the side walls of the panel housings 20 and 40 protect the side surfaces of the display devices 2 and 4 and the input devices 200 and 400 at the joint portion. 13, the portion indicated by "V" is thinner than the panel housing side walls 20 and 40 in order to make the distance between the displays as close as possible. In other words, if it is thinner, it is preferable to have a maximum of 0.05 mm or less, but it may be up to 1 mm.

However, it is not necessarily required, and the portion denoted by " V " may be equal to or slightly thicker than the thickness of the side walls of the panel housings 20 and 40. However, it is too thick to lower the merchantability.

It is generally desirable that the side wall of the panel housing does not exceed a maximum of 1.5 mm so that the thickness of the portion indicated by "V" is at most 1.5 mm. However, the portion indicated by "V" is smaller than the thickness of the panel housings 20 Even if it is wide, it is better not to exceed 2mm.

Consequently, the distance between the displays 2 and 4 can be from a maximum of 0.1 mm to a maximum of 4 mm. Of course, the thickness of the portion indicated by " V " does not necessarily have to be 2 mm in order for the distance between the displays 2 and 4 to be 4 mm, 400 side is in close contact with the portion indicated by " V "

For example, the distance between the displays 2 and 4 can be 4 mm even if the thickness of the portion labeled "V" is only 0.5 mm. That is, the present invention provides a structure for bringing the distances between the two displays 2 and 4 close to each other, so that the distance between the displays 2 and 4 should be at least 0.1 mm and not exceed 4 mm will be. If it is apart, it may be a space as it is, but it may be provided with a tough member absorbing impact.

Naturally, since the distance between the displays 2 and 4 and the distance between the input devices 200 and 400 are the same, the distance between the displays 2 and 4 is the same as that between the input devices 200 and 400 So that the distance between the input devices 200 and 400 is at least 0.1 mm to at most 4 mm.

14 shows an embodiment in which the distances between the displays are closer than the distances between the displays.

When the plate provided between the input devices 200 and 400 is referred to as "V1" and the plate provided between the displays 2 and 4 is referred to as "V2", the distance of "V1" small. That is, the distance between the display devices 2 and 4 is shorter than the distance between the input devices 200 and 400. [

At this time, both of "V1" and "V2" may be formed integrally with the side wall of the joint of the panel housings 20, In this case, two stepped portions are formed on the side walls of the joints of the panel housings 20 and 40, and the input device 200 and the display 2 and 4 are mounted on the respective steps, respectively.

Of course, only "V2" may be formed integrally with the joint side wall of the panel housing 20 (40), and "V1" may be a separate protective film or protective means. In the case of a protective film or a protective means, the protection means or the film embodiment described in Fig. 13 are directly followed.

* Of course, "V1" and "V2" can be used as a separate protective means from the panel housing. In this case, the protective means protects the side of the display (2) (4) and the side of the input device (200) (400).

At this time, the thickness of "V2" follows the embodiment of Fig. Only the thickness of "V2" becomes thinner. For example, it can be from 0.005mm to 0.5mm when it is in the form of a film, and it should not exceed 1.5mm when it is in the form of a plate.

Therefore, in the embodiment of FIG. 14, the distance between the input devices 200 and 400 is within a range of at least 0.01 mm to 3 mm. Naturally, "V1" does not necessarily have to be 1.5 mm so that the distance between the input devices 200 and 400 becomes 3 mm.

Even if "V1" is 0.5 mm, the distance between the input devices 200 and 400 can be 3 mm. There may be some distance between the input device 200 (400) and "V1 ". And, if it is apart, it may be a space as it is, but it may also be provided with a shock absorbing member for absorbing impact.

Figures 15a and 15b are views of an embodiment with optical means.

15A shows an embodiment in which the displays 2 and 4 are closely attached to the side walls of the panel housings 20 and 40. Fig. The panel housing side walls 20 and 40 of the portion where the display is closely contacted are formed to be thinner than the other portions because the intervals between the displays 2 and 4 are close to each other.

However, as shown in FIG. 12 to FIG. 14, the side walls of the panel housings 20 and 40 at the portion where the display 2 and the display 4 are in close contact need not be thinner. Therefore, the distance between the displays 2 and 4 is the same as in the previous embodiment.

The optical means 27 may be provided at the upper end of the display 2 or 4. The optical means may be an optical means for changing the refraction of light such as a lens, a microlens, a micro prism, or the like, 8) direction.

The optical means serves to reduce a screen non-display area which is a boundary line between displays. Therefore, the optical means are provided so as to be in contact with each other. Of course, a protective film or the like can be seen on the side of the optical means 27.

15B shows that there are "V3" and "V4" between the display 2 and the optical unit 27. The "V3" and the "V4" correspond to the side walls of the panel housings 20, Or may be formed as a separate protective member separate from the panel housings 20 and 40. The protective member may be made of transparent or opaque plastic resin or alloy metal.

Naturally, " V3 " and " V4 "may be formed thinner than the panel housings 20 and 40, formed to the same thickness, or may be thicker depending on the situation.

That is, the distance between the displays is preferably within 4 mm, and the distance between the optical means 27 is preferably within 2 mm.

15C is a view of an embodiment in which the display 2 and the display 4 and the optical means 27 protective film 14 are provided. As shown in the figure, a protective film is provided so that the distance is maximized. Naturally, the protective film is within 0.5 mm.

For this purpose, an attachment unit 16c is provided on the side surface of the chassis 16 so that the input device is attached. Here, the attachment portion 16c may be a double-sided adhesive, or an adhesive such as an adhesive bond may be used.

16a are views separated from each other, and 16b shows a state in which an input device is mounted on the display 2, 4.

The chassis is not necessarily made of a metal material, and may be in the form of a structure made of a plastic resin. It is also possible to use a mixture of metal materials and plastic materials. That is, in the present invention, the chassis generally refers to a structure in which a display part is mounted.

17A to 17C are detailed views of a display and an input device.

FIG. 17A is an enlarged view of a portion A indicated by circles in FIG. 16A.

In the present invention, since the two screens are connected to minimize the joint, it is necessary to design to reduce joints on the display.

The distance J between the adjacent pixel 2n and the partition 2f may be less than 1 mm when the pixel 2n is closest to the joint 8 as shown in FIG. Of course, there is no big problem even if J value is zero.

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 to the edge of the display (2) (4) between the pixel (2n) closest to the joint and the edge of the display (2) should be within a range of 0.02 mm to 2 mm.

Here, the barrier rib 2f denotes a boundary between the inside and the outside of the display. That is, a sealant may be used, or when the display substrate is made of glass, it may be a glass material or a metal material when the substrate is made of a metal material. In other words, the display (2) (4) Panel (part that functions as a screen display)

On the other hand, the displays 2 and 4 are usually mounted on a chassis 16, which is made of a metal such as aluminum or an alloy. A display module and a display driving unit or a backlight unit (when the display is an LCD) are mounted on the chassis.

* At this time, the chassis need not necessarily be made of metal but may be in the form of a structure made of plastic resin. It is also possible to use a mixture of metal materials and plastic materials. That is, in the present invention, the chassis generally refers to a structure in which a display part is mounted.

Further, it is assumed that the thickness of the chassis 16 does not exceed 0.01 mm or more and 1 mm or less. However, the maximum effective thickness of the chassis 16 should not exceed 0.5 mm. Therefore, the distance from the nearest pixel 2n to the boundary of the chassis 16 in the joint portion 8 is 2.5 mm at the maximum and 0.03 mm or more at the minimum.

It is needless to say that the boundary between the boundary line 2g of the joint portion 8 and the partition wall 2f does not need to completely coincide and it is natural that the partition wall can be provided within a range of 0.5 mm or less from the boundary line 2g. In this case, the distance from the nearest pixel (2n) to the boundary of the chassis (16) at the joint portion (8) is 3.0 mm at the maximum.

That is, in the present invention, the screen non-display region of the joint portion is a sum of the J value, the K value, and the thickness of the chassis, and the maximum value is 3.0 mm. When two displays are interconnected, .

FIG. 17B is an enlarged view showing part B of the circle in FIG. 16A. FIG.

When an input device is mounted on the top of the display 2 or 4 of the present invention and the input device is mounted on the top of each of the displays 2 and 4, You have to change the design to make it look like you are using it.

Typically, the input device 200 is mounted on the top of the display to input or select information.

That is, in the input device, lead wires for reading a capacitance value or a resistance value are provided on each side of the input device. In this case, the position of the lead wire 250n in the joint portion must be changed. The partition wall 250f may also exist.

The distance M between the lead wire 250n and the partition wall in the joint portion 8 is set to a minimum of 0.01 mm to 1 mm and the thickness L of the partition wall 250f is also set within 0.01 mm to 1 mm. It goes without saying that the interval M may be 0 mm, of course.

Therefore, the distance between the lead wire 250n and the boundary 250g of the input device 150 in the joint portion 8 is at least 0.02 mm to 2 mm.

Of course, it is needless to say that the boundary between the boundary 250g of the joint 8 and the partition 250f does not need to completely coincide with each other, and it is of course possible to provide the partition 250f within a range of 0.5 mm or less at the boundary 250g . In this case, the maximum value to the lead wire 250n and the boundary line 250g is 2.5 mm.

On the other hand, the partition wall 250f does not necessarily have to exist depending on the input device system such as the capacitance type. In this way, the distance between the boundary line 250g and the lead line 250n is set within 0.01 mm to 2.5 mm.

Reference numeral 250a denotes an information input portion of the input device, and its structure differs depending on the resistance film type and the capacitance type. That is, information is input by applying pressure to the input unit 250a.

In the present invention, the input device is not necessarily limited to the capacitive type and the resistive film type. The input device is composed of a flat plate made of plastic or glass, electrodes are formed on the flat surface, Means all manner of.

On the other hand, FIG. 17c shows a sectional view of the display, where the pixel electrode has a shape closer to the joint portion.

The distance between the display boundary 2g and the closest pixel 2n is very important in the joint 8 regardless of which display is used, It is a matter of course that the design values designed in the present invention can be directly applied to all flat panel displays.

In the portable display device of the present invention, an OLED method is used, and a cross section of the structure is shown.

The displays 2 and 4 are provided with an insulating layer 53, an electrode 54, a coating electrode 58 and an organic multi-layered film 53 on a substrate 51, (56).

Then, the substrate 51 is covered with the cover substrate 52. At this time, the barrier rib 2f may be a sealant formed of an adhesive or the like, but it is a matter of course that the substrate can serve as the barrier rib 2f.

That is, when the substrate surface is partially removed by the etching process to form a space inside the substrate surface, and then an insulating layer and an organic multilayer film or an electrode are formed, the edge portion of the substrate remaining in the etching process acts as a partition wall 2f It is natural to be able to do it.

On the other hand, in the joint portion, the chassis covers only the side surface. However, when covering the upper portion, only the portion P corresponding to the screen non-display region should be covered.

17d is a view showing an active area and an input device boundary. Further, an embodiment of a capacitive input device is shown. As shown in the figure, there is no electrode line between the boundary 223a of the active area 223 and the input device boundary 250g. And the distance from the active area boundary 223a to the input device boundary 250g is within 2.5 mm.

- Example 9 -

18A is a view in which a display equipped with an input device is mounted on a panel housing.

The input device 200 is provided and the seam 8 of the display 2 or 4 is mounted on the upper end of one side wall 20a of the panel housing.

Shaped cover 24 is provided at the upper end of the panel housing 20 so as to cover an edge of the display 2 or 4 which is an aspect ratio display area.

Further, a lyophobic button 110, a speaker 101 and the like may be mounted on the lid.

FIG. 18B shows a case in which a "L" shaped cover is formed, but a joint portion is formed to be thinner. That is, as shown in the drawing, the portion indicated by 24a in the lid 24 is formed to be thinner and thinner because the portion denoted by 24a is formed within the screen non-display region shown in FIG. 17A.

That is, in the present invention, the cover 24 covers the screen non-display area, and the screen non-display area is formed so that the joint part is made smaller than the other parts.

19 is a perspective view of a panel housing with a display mounted thereon.

As shown in the figure, the cover is mounted on the upper part of the display screen non-display area. FIG. 18A is a view showing an embodiment of a "C" shape cover (FIG. 18A). The display area has a screen display area. If the screen display area is referred to as an active area, the active area is positioned closer to the joint area. That is, in the joint portion, the screen non-display area becomes smaller.

In the drawings, the display device 2 is shown for convenience, but the display device 2 means the display device 2 in which the input device 200 is mounted, and the reference numerals for the input device are omitted in order to avoid confusion.

It is a matter of course that the "ㅁ" shaped cover (FIG. 18b) can also be mounted on the panel housing on the same principle.

20 is a view of an embodiment in which a display and an input device are separately mounted in a panel housing.

As shown in the figure, the display 2 and the input device 250 are separately mounted on the panel housing 20, and the lid 24 shown in FIGS. 18 and 19 is not provided.

Therefore, the input device 200 also serves as an external shield for protecting the surface of the display 2 in the portable display device.

At this time, a "C" mask printing (Mask Printing) 16d is performed on the input device 200. The mask printing 16d blocks the edge aspect ratio display area of the display (2) and (4). The blocking effect is more visual.

Here, mask printing is performed on the input device 200 by performing mask printing on a protection film or a protection plate on the upper portion of the input device.

It is also possible to make the mask printing 16d " square " like in the embodiment of another mask printing 16d in the original. However, it becomes thinner at the joint part.

* The active area existing on the display is located closer to the joint portion, and the mask printing 16d is also formed thinner because the screen non-display region is smaller in the joint portion.

In the present invention, the input device is not necessarily limited to the capacitive type and the resistive type. The input device is formed of a flat plate made of plastic or glass, electrodes are formed on the flat surface, Means all manner of.

21A-21C are views of another embodiment in which the display and the input device are separately mounted to the panel housing.

The display devices 2 and 4 are mounted on the panel housings 20 and 40 and the input devices 200 and 400 are mounted on the upper surfaces of the panels 2 and 4. At this time, the input device 200 or 400 is assembled with the " C " -shaped cover 24 to be provided at the upper end of the display 20 or 40.

Of course, the "C" shaped lid 24 and the lower panel housings 20, 40 are firmly coupled to each other by a connecting screw or the like.

In addition, a step is formed between the lid 24 and the input device 200 (400) to some extent, and the degree of the step is within 2 mm.

The panel housing 200 is provided with a cutting portion 6a and the connecting means 6 is located on the cut portion 6a.

In the present invention, the input device 200 is mounted on the cover 34, but the structure of the cover is not limited. That is, it may be a frame form. If it is a frame type, it also serves as a cover but also acts as a support, so that the side wall and the cover are connected to each other.

FIG. 21B shows a shape in which the input device is mounted on the cover of the "? -Shaped " shape. Naturally, the joint is formed to be thinner and thinner as in FIGS. 18 and 20.

Also, the "ㅁ" shaped cover is mounted like a "C" shaped cover.

FIG. 21C shows a lid in the form of a frame. That is, as shown in the figure, lid side walls 24a are provided at both edges of the lid 24. A flame-like lid that serves as a lid and serves as a panel housing sidewall. It is therefore obvious that the joint portion 8 has a structure in which the lid side wall 24a can be in close contact with the side of the display 2 or 4 or the side of the input device 200 or 400. [

12 to 15C corresponds to the side wall of the panel housing, but the embodiment from FIGS. 12 to 15C can be applied to the side wall 24a of the cover as it is. That is, the cover side wall 24a may be cut so that the distance between the display 2 and the input device 400 or the input device 200 is closer to the display device 2, The protective film or the protective film for protecting the side of the light emitting device 200 (400).

It is a matter of course that the side of the display 2 4 can be closely attached to the side walls of the panel housings 20 and 40 and only the side of the input devices 200 and 400 can be brought into close contact with the side wall 24a of the cover.

It is also possible that the sides of the input devices 200 and 400 and the displays 2 and 4 can be in close contact with the sidewalls of the panel housings 20 and 40 and the lid sidewalls 24a, .

When the lid 24 provided with the lid side wall 24a or the lid 24 without the lid side wall is engaged with the panel housings 20 and 40, It is of course possible to combine them by the method of Fig. That is, this combination is. That is, it depends on the coupling method.

In addition, the frame shape of the lid is designed to provide rigidity to the panel housing, and it may be of course used as a metal material such as an alloy or a liquid metal in addition to the sake.

22 is a diagram showing an actual arrangement of a display and an input device.

Although one display and an input device are shown for the sake of convenience, the present invention has a structure in which two displays and two input devices are connected to each other.

Conventional displays and input devices are provided with a connector for connecting with the terminal body. In the present invention, the connector position is changed.

As shown in the figure, the displays 2 and 4 and the input device 200 are provided so as to have a mutually symmetric structure about the joint portion 8. The flexible printed circuit (FPC) 2c, 4c and 250c connecting the display device and the input device to the connectors 2d and 250d are provided. The FPCs 2c, 4c and 250c ) Is mounted on the opposite side of the joint.

At this time, the connector 250d of the input device 200 may be connected to the junctions 2e and 4e of the display 2 and 4 by circuit soldering. In this case, the connection between the input device 200 and the main body can be achieved by the connection between the connectors 2d and 4d of the display 2 and the main body. That is, the display connectors 2d and 4d may include the function of the input device connector.

Then, an external signal line (FPC) is connected to one side of the display and the input device, and the external signal line is positioned on the opposite side of the joint portion.

Of course, when the display device 2 and the input device 200 are separated from each other and are separately mounted on the panel housings 20 and 40 (the embodiment of FIGS. 20 and 21) When connecting the external signal line (FPC), one of three sides except the joint part 8 can be selected and connected.

23 is a view showing one electrode structure of the display panel.

In general, a display panel is a glass substrate, and in some cases, a transparent plastic substrate (hereinafter referred to as a " transparent substrate " .

23 is a view showing a display panel. When the four sides are referred to as 1, 2, 3, and 4 sides, respectively, if the first side is referred to as a joint portion, the drive driver 2k is mounted on the third side, which is the halfway.

Normally, the display sends a drive signal on both sides by driving a matrix. However, in this case, there should be at least two driving drivers. Thus, the supply line 2g connected to the panel electrode 2f at the second side and the fourth side is connected to the third side. Therefore, it is possible to send signals to the display panel by only the driving driver 2k mounted on the third side.

24A to 24C are views showing the shape of a display panel of another embodiment.

Fig. 24A shows that the portion where the drive driver 2c is located is the fourth side when the first side is the joint portion. That is, when the joint portion is set to the right side (left side as the case may be), the portion where the drive driver 2k is located becomes upward or downward.

And to the fourth side of the supply line 2g connected to the panel electrode 2f on the first side or the third side to mount the drive driver 2c on the fourth side. That is, the supply line 2g is divided into one side and three sides to reach the fourth side. At this time, the supply line 2g is an electric wiring connected to the drive driver 2k to supply a signal line. In the present invention, the electrode 2f is simply expressed, but actually means a TFT (Thin Film Transistor) or a pixel electrode.

Therefore, in this case, a margin of 1.5 mm is given to the maximum arm of 2 mm which is the sum of the "J" arm and the "k" value shown in FIG. 17A. That is, the distance for the supply line 2g to pass through is secured. Therefore, it is preferable that the distance from the pixel nearest to the display joint portion 8 to the boundary of the display (2) (4) does not exceed a maximum of 3.5 mm.

In this case, the screen non-display areas of one side and three sides may be the same or different, but the design effect is the same.

At this time, the screen non-display area of the third side may be within 5.5 mm.

FIG. 24B is another embodiment of a modified connection supply line,

When the first side is referred to as a joint portion, the supply line 2g does not pass through the first side in order to minimize the joint portion. The supply line 2g passes through the third side opposite to the joint portion 8 and the supply line 2g meets the drive driver 2k. In this case, the distance from the pixel nearest to the joint portion 8 to the boundary of the display 2 (4) at the first side can be 2.0 mm at the maximum.

FIG. 24C is a view showing a case where two displays are arranged. FIG.

The FPC 2c 4c and the external connection connectors 2d and 4d connected to the drive driver are connected to the lower side of the display 2 In some cases it may be the upper side).

Likewise, the FPC 250c and the connector 250d for connecting the input device are also located below.

- Example 10 -

25A-25C are views of another embodiment in which the display is mounted to the panel housing.

25A, the "? &Quot; -shaped cover 34 is covered at the top of the panel housing as shown in the figure. That is, as shown in FIG. 18A, the panel housing 20 is mounted with the display shown in the embodiment of FIGS. 25A and 25B, and a cover 34 shaped like "?" Of course, the input device 200 may be mounted on the display 2 as shown in FIG.

That is, the side opposite to the joint portion 8 is provided with the side wall or the protection means of the panel housing 20 beside the display 2, and the screen non-display region above and below the display 2 is shaped like a & The lid 34 is covered.

Fig. 25B is a view of another embodiment of the lid. The panel housing 20 is equipped with the display 2 shown in the embodiment of Figs. 24A and 24B, and is fitted with a lid having a shape like " In the "ㅁ" shape only, the left and right portions are formed thinner than the lower portion.

The lower portion is the portion where the drive driver 2k is mounted on the display 2 and 4 and therefore the left and right portions of the cover 34 are formed to be thinner than the upper portion do.

Reference numeral 25c denotes a lid 34 in the form of a frame. A lid side wall 34a is further provided at the lid edge as shown in Fig. And the cover side wall 34a is applied in the same manner as the embodiment of the cover side wall 24a of Fig. 21C.

25D is a view showing the panel housings 20 and 40 mounted with the displays 2 and 4 shown in the embodiment of Figs. 24A and 24B interconnected by the connecting shafts 61 and 62. Fig. As shown in the figure, the joint portions of the displays mutually connected are small.

Although the seam is somewhat larger than the "c" shaped cover, the screen can be enlarged to the left and right to have the effect of viewing a larger screen.

26 is a view of an embodiment in which an input device is mounted on the lid.

Although the display is mounted on the panel housing 20 as shown in the figure, the cover 34 is mounted on the panel housing 20 in a form in which the input device 200 is mounted on the cover 34, .

At this time, depending on the situation, it is natural that a shield plate is used instead of the input device and tempered glass can be used.

At this time, the input device 200 may serve as a shielding plate, and in the case of a portable display device in which an input device is not required, a bellows plate made of tempered glass or reinforced plastic may be provided instead of the input device 200.

* Of course, the cover may have a flame shape and serve as a side stiffener rather than a cover. However, since the structure is not so different from the cover, a separate illustration is omitted. It can be said that a portion that serves as a part of the side wall can be formed as a connection.

In the present invention, an embodiment in which the input device 200 is mounted on the cover 34 is shown, but the structure of the cover is not necessarily limited. That is, it may be a frame form. If it is a frame type, it also serves as a cover but also acts as a support, so that the side wall and the cover are connected to each other.

27A and 27B are views of another embodiment in which an input device is mounted.

27A is a view showing an embodiment in which the input device 200 functioning as a shielding plate is directly mounted on the panel housing 20. Fig. As in the drawing, an input device that is mask printed (16d) in the shape of " = " is mounted directly to the panel housing. The principle that the display 2 is mounted on the panel housing 20 is the same as in the previous embodiment.

27B, the input device 200, which is mask printed 16d in the shape of " ㅁ, " is mounted directly to the panel housing 20. [ However, the left and right are formed thinner than the upper or lower side.

26 and 27A and 27B, it is of course possible to provide a structure in which two displays 2 and 4 can be folded and unfolded while being adjacent to each other.

- Example 11 -

28 and 29 are views of another embodiment of a frame for mounting an input device.

28 is a view of an embodiment in which the input device 200 is mounted on the cover frame 24. Fig. The cover frame 24 has a shape in which the joint portion 8 is opened in a rectangular shape. That is, the lid frame 24 covers the edges of three sides of the display 2 except for the seam. On the other hand, the lid frame 24 is provided with a cutout 24f so that the shaft can be positioned. As a result, the lid frame 24 also has a joint. The joint portion of the lid frame 24 is positioned at the joint portion 8 of the display 2 and the joint portion 8 of the input device 200 is also located there.

29 is a view of an embodiment in which the input device 200 is mounted on the frame 20b. At this time, the frame 20b is formed with a joint portion which is opened or thinned on one side, and a mask printing 16d is formed on the input device 200. [ The mask printing 16d blocks the edges of three sides except for the seams when the edges of the upper part of the display 2 are covered.

Naturally, the joint portion of the frame 20b is mounted on the joint portion 8 of the display 2, and the joint portion of the input device 200 is also mounted. On the other hand, the lid side wall 24d may be provided in the input device coupling part 200, may not be provided according to circumstances, or may simply be provided in the form of a protective film.

28. Similarly, a lid side wall 24d or a protective film may be provided on the joint portion of the lid frame 24 shown in the embodiment of Fig.

At this time, the mask printing 16d means that the top of the input device or the protection plate is coated with a pattern or a color to block light, so that the portion where the mask printing 16d is formed appears opaque.

Further, in the present invention, when the lid frame 24 or the frame 20b is mounted to the panel housing 20, it is natural to mount the lid frame or the frame 20b with a groove, a projection or a screw, So that the present invention is not shown.

Figure 30 is another type of frame. That is, the cover frame 24 and the frame 20b are combined together. The upper portion and the lower portion are provided in the form of a cover 24, and the side portion is provided with a mask printing 16d. Although the lid 24 and the input device 200 are different in height from each other in the figure, the height of the lid 24 and the input device 200 may be equal to each other, .

31 shows a structure in which a plate-shaped optical means 27 having a predetermined thickness can be placed on the top of the input device 200. That is, the optical device 27 can be placed on the top of the input device 200 and can be removed as needed.

For this purpose, the material of the portion where the screen is not displayed at the bottom of the optical means may be made of a material having a property of sticking to the glass or the plate due to its high coefficient of friction. Or if the frame 20b is formed somewhat higher as in the drawing, it may be designed so as to have an optical means inside the frame and serve to hold the optical means 27 with the frame.

32 is a view of another embodiment in which the cover frame 24 and the mask printing 16d are mixed. That is, the thickness of the cover frame 24 is reduced, and the mask printing 16d is also used.

In this case, the size of the screen can be made larger than the case of using only the cover frame 24, and a reliable panel housing structure can be formed rather than using only the frame 20b.

On the other hand, when the input device sensor is provided in the cell of the display 2 (4), the input device 200 (400) need not be provided. However, a protective cover shall be provided. Therefore, a protective plate is attached to the shape of the lid frame 24 or the frame 20b provided in the eleventh embodiment in place of the input devices 200 and 400.

Example 12 -

33-36 are views of an embodiment of reducing the number of displays.

That is, it is not necessary to mount the auxiliary display 30 shown in Fig. 2. In order to know the state of the display device even when the folding display device is closed, the auxiliary display 2 must be mounted on the outside.

In that case, three displays will be used. However, by using both sides of the display 2 as in the twelfth embodiment, it is not necessary to further use the auxiliary display.

FIG. 33 shows an outer window 29 in a partially folded form, and a protective plate 29a or an input device is mounted on the outer window 29. FIG. In addition, the external window 29 is provided with an input device instead of the protection plate 29a for protecting the display, so that the portable display device can be controlled from the outside by a touch panel method.

Fig. 34 is an exploded view of the panel housing 20 provided with the external window 29. Fig. That is, a protective plate or an input device 29a is mounted through a step provided in the external window 29, and an OLED type display 2 is mounted inside the panel housing 20. [

34, the lid 24 covers the backside of the display 2. However, the lid 24 covers the display. It will be appreciated that the lid 24 may be applied to the frame 20b or cover frame 24 of various forms shown in other embodiments of the present invention.

In addition, the lid 24 is equipped with an input device 200 or a protective plate. Likewise, the input device 200 is also applicable to an input device of the type shown in another embodiment of the present invention.

When the panel housings 20 and 40 are closed, a screen is normally displayed on the front surface (as viewed in the drawing) of the OLED 2. When the panel housing is unfolded, The screen is normally displayed on the back surface (as viewed in the drawing) of the display device.

That is, data on the screen display is inverted. Such a display method is controlled by inputting by a program.

35 and 36 are block diagrams or flowcharts of the present embodiment.

As shown in Fig. 35, the central processing unit 105 is control means for controlling the overall operation of the portable display device of the present invention. The RAM 121 controls the execution program of the display device. The RAM 122 stores data generated during the execution of the program. The RAM 123 stores data required by the user and data .

The R / F unit 124 is a radio frequency, tunes to an RF channel, amplifies an input voice signal, and converts an RF signal received from the antenna into an intermediate frequency signal. The input unit 110 includes various input devices, a numeric key, a menu key, and a selection key.

There are display driving circuits 2a and 4a for driving the display by the output of the central processing unit 105 and first and second displays 2 and 4 for displaying information on the screen in accordance with the output signal of the driving circuit, .

And a sensor 235 which senses whether the two panel housings 20 and 40 are in an unfolded or open state. For example, it may be provided on the sensing electrode on the rotary shaft, or may have an optical sensor to sense an open state when the panel housing is opened. That is, a normal sensor that detects opening and closing of the case.

In addition, the central processing unit controls the first and second input devices 250-1 and 250-2 through the first and second input device drivers 1401-1 and 140-2. That is, since there are two input devices 250-1 and 250-2, two input device drivers 1401-1 and 140-2 exist to control the corresponding input devices.

The input devices 250-1 and 250-2 shown in the block diagram of FIG. 10 are the same as the input devices 200 and 400 shown in the other drawings of the present invention. Although an example of an input device to be mounted on the outside of the display is shown in the embodiment of the present invention, it is obvious that the same principle can be applied to the input device sensor provided in the display cell.

36 is a flowchart. When the portable display device is operated (step 300), the sensor 235 is output. That is, it detects whether the panel housings 20 and 40 are in a closed state or an open state.

If the panel housing is open (step 310) (step 315), the two screen driving modes are selected. That is, in the screen mode stored in the memories 121, 122 and 123, two screen driving modes and a single screen driving mode are stored. Then, the central processing unit 105 selects the two-screen drive mode.

The memories 121, 122 and 123 also store data processing information for displaying the rear side of the display 2 and data processing information for displaying the front side. 33 and 34, information may be displayed on the front surface of the display 2 or information may be displayed on the rear surface.

Accordingly, the central processing unit 105 sends a signal for displaying information to the back of the display 1 (2) to the driver 2a of the display 1 (2). Then, the portable display device performs the function (step 325)

When the panel housings 20 and 40 are closed, the central processing unit 105 selects a single screen mode among the information stored in the memories 121 and 1220 (step 330) To the driving unit 2a of the display 1 (step 335)

Then, the function is performed in the single screen mode (step 340)

In addition, if there is a termination or stop command (even if it is not used for a predetermined period of time, it is included in the stop command), the portable display device is terminated or stopped. Otherwise, the initial sensor detection state is returned.
