1B is a view showing a state where the foldable portable display device of the present invention is folded.

The cover unit 10 is provided at the side of the panel housing 20 and 40. The cover means protects the sides of the display 2, 4.

In addition, the cover means 10 covers the side surfaces of the displays 2 and 4 when the panel housings 20 and 40 are folded, and the cover means when the panel housings 20 and 40 are unfolded. 10) will not protect the sides of the display (2) (4). This is because the panel housings 20 and 40 should be positioned close to each other so that the display forms one screen.

1C is a view illustrating a state in which the cover means is removed from the display device.

The panel housings 20 and 40 are provided with an accommodating space 60 for accommodating the cover means 10, and a gap between the display 2 and the display 4 has a seam gap 8a. Of course, the gap between the display 2 and the display 4 can be made very narrow so that there is almost no seam clearance 8a.

In FIG. 1C, the sides of the display 2, 4 are shown in dashed lines to indicate that the sides of the display 2, 4 may or may not be exposed. That is, in the structure of FIG. 2A, the side surface of the display 2 will be exposed. However, if the connection joints 20a and 40a exist as shown in FIG. 2C, the side surfaces of the display 2 and 4 will not be exposed. When the panel housings 20 and 40 are unfolded, the cover means 10 folds and unfolds the panel housings 20 and 40 so that the displays 2 and 4 do not interfere with each other. Move along. To this end, by connecting the panel housings 20 and 40 and the cover means 10 with the elastic device 10a, the cover means 10 can move together in accordance with the unfolding and folding of the panel housings 20 and 40. will be.

2A to 2C are cross-sectional views of the panel housing in an unfolded state.

2A is a view showing that the display (2) (4) is provided on the top of the panel housing (20, 40). As shown in the figure, when the panel housings 20 and 40 are unfolded and in close contact with each other, the displays 2 and 4 are adjacent to each other.

At this time, when the panel housings 20 and 40 are unfolded, the panel housings 20 and 40 are portions in which the panel housings 20 and 40 are in close contact with each other so that the displays 2 and 4 are adjacent to each other. Display (2) (4) on the upper side of the side. In this case, in order for the displays 2 and 4 to be adjacent to each other, the side surfaces of the panel housings 20 and 40 are cut out to form the openings 8b. In other words, the displays 2 and 4 are in contact with each other through the opening 8b.

That is, when the panel housings 20 and 40 are unfolded, the display 2 and 4 are connected to each other so that one screen is formed through the cut sides of the panel housings 20 and 40.

In addition, various circuits and devices 25 and 45 are provided inside the panel housings 20 and 40, and support members 26 and 46 are also provided to support the displays 2 and 4. The cover 24 is provided at the edges of the display 2 and 4. On the other hand, the cover means 10 is omitted for convenience. When the panel housing is unfolded as in the description of FIGS. 1B and 1C, the cover means 10 is positioned behind the display 2, 4 without covering the sides of the display 2, 4.

In addition, the extension line of the center of rotation A meets the surface of the cover 24. In other words, the height of the center of rotation is the height of the cover.

2B is a view of an embodiment with a protective means on top of the display. As shown in the figure, the display 24 and the panel housings 20 and 40 are provided with steps 24a and 20c, and the protection means 14 are mounted on the steps 24a and 20c. (4) The protection means 14 protects the side and the front of the display 2, 4, which are screen displays. In addition, the protection means 14 may be formed to have a thinner side than the front surface to minimize the seam 8 portion, which is a non-display area of the screen. And when the side of the protective means 14 is in the form of a protective film, since the protective film should be as thin as possible and firm, it can be used as a material coated with a metal or inorganic film on the metal film or resin film.

An optical means 27 may be provided below the protective means 14. At this time, it is obvious that the protection means 14 and the optical means 27 can be integrated. Here, the optical means means a micro prism or a micro lens, and the protection means 14 and the optical means 27 are integrally formed to mean that the micro prism or the micro lens is formed under the protection means 14. The protective means is formed to be thinner than 2mm or 1mm or less or 0.5mm or less.

2C is a view of an embodiment with a connecting seam on the side of the panel housing. When the panel housings 20 and 40 are unfolded, the displays 2 and 4 are adjacent to each other, and the connecting joints 20a and 40a are provided therebetween. Therefore, the joints 20a and 40a block the opening 8b. That is, the side surfaces of the panel housings 20 and 40 that are in close contact are cut to form the openings 8b or the connection joints 20a and 40a so that the displays 2 and 4 are adjacent to each other.

The connection joints 20a and 40a may be thinner than other portions of the panel housings 20 and 40, or may have a thickness of 1 mm or less or 0.5 mm or less.

As a result, when the opening 8b is formed in the panel housing 20 and 40 as shown in FIG. 2A, at least one side of the display 2 and 4 comes into contact. And, as shown in Figure 2b and 2c, if the display is closely connected through the protective means 14 or the connecting portion 20a, 40a, the display (2) (4) is at least 4 mm or less than 5 mm or less They are placed close to each other. In some cases, they are arranged close to 2 to 3 mm or less.

That is, two or more of the display (2) (4) of the present invention is used to have a structure that is arranged close to each other and connected to each other so that one screen can be seen.

Figures 3a to 3c is a view showing the instrument on which the display is mounted.

Typically, the display 2 includes not only the display panel 2a but also the driving circuit board 40 backlight 30 and the mechanism 160. Accordingly, the display 2 and 4 mean the mechanism 160 on which the driving circuit board 40, the backlight 30, and the like are mounted, as well as the display panel 2a. In the present invention, the side surface of the appliance 160 is also cut where the joint portion 8 of the display 2 is located. By doing so, the non-screen display area between the displays 2 and 4 can be minimized. That is, the fixture 160 is provided with connection joints 160e and 160f to minimize the non-screen display area.

In addition, the driving circuit board 40 is provided with a locking portion 161 and a locking hole 161a in the mechanism 160, and the mechanism 160 is mounted in the panel housing 20 and 40 through the locking portion and the locking hole. It is attached to the inside or the chassis (16) chassis. In this case, the connection joint of the appliance 160 is mounted on the joint 8 of the panel housing 20 and 40. Therefore, the screen non-display area can be minimized.

Figure 3b is a view showing the open side of the appliance connecting joints 160e and 160f by completely cutting the side of the appliance.

And, Figure 3c is a view of an embodiment in which the mechanical connection joints (160e, 160f) are formed thin. That is, it is a figure which shows the connection joint parts 160e and 160f formed thinner than the other part of the apparatus, the thickness is formed in 0.5 mm, or in some cases within 0.3 mm. In FIG. 3C, the connection joints 160e and 160f are illustrated by dotted lines in order to show that they are formed thin.

The instrument plate 160a is equipped with a backlight, a display panel 2a, 4a, and the like.

As shown in the drawing, the display panel 2a, the driving circuit boards 2b, 2c, and the like are mounted in the chassis 16. The drive circuit board is usually used in a film type structure. The display 2 and 4 may refer to the chassis 16 in which not only the display panel 2a but also the driving circuit board 40 and the backlight 30 are mounted.

In addition, the chassis refers to a structure surrounding the display, the display driving circuit, and the like with a metal material such as aluminum. Here, the driving circuit boards 20b and 20c may be mounted to the chassis 16 or the mechanism 160 in a state of being folded into the external electrode portion 2k of the display panel 2a. When the driving circuit boards 2b and 2c are folded to the external electrode portions 2k connected to the upper and lower plates 2i and 2j of the display panel 2a, the size of the display becomes smaller.

4B is a cross-sectional view showing that the display panel 2a, the circuit, and the backlight 30 are provided in the chassis 16. In the part where the seam 8 is provided, the chassis 16 covers only the side surface of the display panel 2a. This is because the non-display area of the screen is minimized when only the side surface of the chassis 16 and the upper portion 8 are not wrapped.

In the present invention, the seam 8 means a portion where the displays 2 and 4 are closely connected to each other.

In other words, the connection portion 16a to which the display 2 and 4 are connected in the chassis 16 is meant to have a structure surrounding only the side of the display. Of course, in order to reduce the screen non-display area, the connecting joint portion 16a of the chassis 16 may be formed thinner than other places.

In addition, the chassis 16 is provided with a locking portion, through which the chassis 16 is fixed to the panel housing 20, 40, wherein the connection joint of the chassis 16 is panel housing 20, 40. To the joint (8) of the. Therefore, the screen non-display area can be minimized.

In FIG. 10A, a signal connection line 83 ′ having a round shape is shown. Similarly, a connector 83 a ′ is provided.

If the signal connection line 83 'is rounded, the area occupied by the signal connection line in the display device is reduced by that much.

10B is a view illustrating a signal connection line in an FPC form.

It is a case where the circuit connection line was formed in the printing form in the thin plastic film so that it may be flexible and bent.

11A to 11D are views for explaining the center of the rotating shaft as the connecting means.

The present invention uses a rotating shaft as the connecting means (6). In particular, the panel housing 20, 40 in the present invention will have a structure that is fully extended or fully folded. Therefore, the structure of the rotating shaft, which is the connecting means 6, is changed, and this changing structure can be seen at the center of rotation of the rotating shaft.

FIG. 11A is a bottom view of FIG. 1 viewed from below, showing the arrangement of the two panel housings 20 and 40 and the rotating shaft. FIG. 11B is a partial cutaway of the rotating shaft of the connecting means 6. This figure shows the center of the axis.

11D is a view of the center of the axis. That is, the center of the rotation axis used as the connecting means (6) in the present invention is the extension line of the surface that is in contact with each other when the panel housing is folded, and the extension line of the surface that is in contact with each other when the panel housing (20, 40) is unfolded It is a point of meeting each other. That is, the point where the two extension lines meet is the center of the rotation axis of the connecting means (6).

And, the panel housing 20, 40 of the present invention can be fully unfolded, can be unfolded up to 180.

Of course, this does not mean that the center of the rotation axis, which is the connecting means 6, must exactly coincide with the point where the two extension lines meet. The two extension lines may be located within the portion indicated by dotted lines shown in FIGS. 11B and 11D (denoted by q in the drawing). The part marked q is about one third of the total diameter of the rotating shaft.

In other words, the rotation center of the shaft may be located within the portion indicated by q, which is one third of the rotation shaft. This is because the panel housing 20 and 40 may be shaken during folding and unfolding.

In addition, the rotation axis, which is the connecting means 6, is present at both edges of the panel housings 20 and 40, so that when the panel housing is unfolded, the display 2 and 4 should not interfere with each other.

In addition, although not shown in the drawings, a hole is formed in the connection cutout portion 6a of the second panel housing 40 that meets the insertion shaft 62. At this time, it is obvious that the insertion shaft 62 and the second panel housing 40 may be integrally formed. And, the front view seen from the direction of arrow A of FIG. 13A is shown in FIG. 13B, and the side view seen from the direction of arrow B of FIG. 13A is shown and shown in FIG. 13C, respectively.

13D is a view showing the insertion axis in detail.

Only the insertion shaft 62 is separated from the second panel housing 40 to show only the insertion shaft 62. In addition, the insertion shaft 62 is cut in half and illustrated, and an insertion side plate 62e attached to the right side of the insertion shaft is also illustrated in the drawing.

Where the insertion shaft 62 and the connection cutout 6a meet, a cutout insertion hole 62d is provided, and an insertion connector 62a is provided on the opposite side of the cutout insertion hole 62d. Both the incision insert and the insertion connector have the form of a hole. Also, a hole is formed in the second panel housing where the insertion shaft 62 and the connection cutout 6a meet.

Of course, the insertion shaft 62 and the connection cutout 6a may be integrally formed, and a hole may be formed in a portion where the insertion shaft and the second panel housing 40 or the connection cutout 6a meet.
