Description

Folding display and its coupling device TECHNICAL FIELD

The invention relates to an inter-screen coupling device of a folding display screen, and a folding soft display screen and a coupling device thereof. Background technique

The existing background technology involves three aspects:

(1) About the big screen

a. At present, the display screen for mobile phones is small, which affects the display graphics and Internet access, which hinders the application of WAP, GPRS and 3G. Mobile phones, etc., so large screens are urgently needed. Between mobile phones and personal computers are handheld computers (HPCs) and personal digital assistants (PDAs), most of which have small screens.

b. At present, computer networks, communication networks, and television networks belong to different fields, using different technical standards and operating systems, and having different equipment vendors and operators. However, the integration of the three networks of the Internet, communication network and television network has become a trend, and the pursuit of remote interactive multi-body information (voice, data and image) browsing, processing and transmission anywhere, anytime, including satellite positioning (GPS) and remote control appliances. For this reason, the computer is required to be wireless and the mobile phone to be large-screen; that is, a personal mobile network device with the function of combining a computer and a mobile phone is required. In the present invention, it is called "mobile computer" or "computer mobile phone" (when the computer function is weaker and lighter), that is, "MCC — Mobile Computer-Communicator". Without it, the development of 3G is greatly affected; but the large screen it needs is exactly the bottle head!

c Some mobile small instruments and toys also require large screens.

d '. In the public giant display screen used for advertising, publicity, information command, etc., multiple display modules are installed side by side to form an unfoldable display screen wall, which does not meet certain use or transportation requirements; therefore, a foldable giant screen is required. .

(2) In order to solve the above-mentioned problems, some technical solutions using folding display screens have been proposed, such as: a. The present patent application, Japanese Patent Application Laid-Open No. Hei 5-61423, and the application date is 1991.8.30, "display device", It is hinged, folded in one direction, and turned inward at 120 ° ~ 180 °.

b. This patent application, Japanese Patent Application Laid-Open No. 10-319879, application date 1997.8.30, "foldable display device", proposes a multi-folding and unfolding display screen.

c Chinese patent application, publication number CN 1140271, application date 1996.4.22, "foldable "Display screen", it is proposed to put an optical magnifying element on the edge of the screen, which is covered with a transparent film to improve vision; this will make it difficult to fold.

d. European patent application, EP 0898223A2, date of application 1998.8.11, "—a multi-display electronic device with open and closed states", which proposes the use of a hinge or other similar mechanism to connect and use a locking mechanism; but these are not specifically described mechanism.

The above schemes are all hinged. Among them, when the hinge is disposed on the front of the display screen, there will be a large protrusion, which affects the effect of sensation. In terms of scope of application, they are not specific enough.

Hard-based flat-panel display devices (eg, flat-panel liquid crystal display LCDs made of two hard glass substrates,. Plasma display PDP, electroluminescence display EL, organic electroluminescence display OEL, flat field emission display FED, semiconductor light-emitting tube Display products such as display LEDs) and circuit boards are often called hard display modules; displays assembled with hard modules into a casing are also called hard displays. The above patent application schemes are all directed to this type of hard screen, that is, a commonly used display screen.

(3) Some new flexible base flexible display devices have appeared (display devices made of soft plastic substrates or paper substrates, such as electronic paper). However, how to use such soft modules and soft screens for folding soft display screens such as mobile phones is still technically blank. Object of the invention

The key to the foldable display is a coupling device that connects two adjacent display housings. The purpose of the present invention is to provide a screen-to-screen coupling device, which is easy to fold, unfold and unfold, and is convenient to use; it is also simple in structure and small in size; it has certain rigidity when it is displayed and unfolded; Another object of the present invention is to provide a foldable soft display screen and its coupling device. Technical solutions

To achieve the above object, the present invention adopts the following technical solutions:

1. A coupling device for a folding display screen, comprising a coupling device between at least two display screens (assembled by a hard display module or a soft display module) and adjacent display screens; the coupling device includes a connecting member and a lock Mechanism; the connecting piece enables each display to be unfolded within 90 ° ~ 225 °, and the splicing constitutes an integrated large folding display (there are obvious joint seams between the screens, and the displayed curves are discontinuous There is a ladder (see Figure 1); the locking mechanism is a card that, after the display screens are unfolded, adjacent screens are fastened to each other to ensure that the folding large display screen structure has a certain rigidity and does not occur between screens during use. Relative displacement or rotation. to this end, The connecting member is a bendable connecting member, an elastic connecting member, a hinge connecting member or a bolt on the back of the display case, or some combination thereof;

The locking mechanism uses a rotating card, a sliding card, and / or a folding angle card; when all the display screens are folded and not used, they must be packed in a bag, or they are locked and locked together by ordinary hooks or elastic marble structures.

2. The above-mentioned bendable connector is a connector that is fixed on the inside of the side shell of the display with glue or / and screws and riveting (see Figures 2, 4, 5a, 7b, 8, 11), or with the display A connecting member with the same shell material and integrated with the screen shell, that is, the bonding length between the connecting member and the inner side of the screen edge shell is zero.

3. The upper flexible connecting piece is a connecting piece which is located in the display case, the ends of which are fixed with glue or / and screws and riveted to the display case; its core problem is the length, which should be determined by the elasticity of the material and The thickness of the screen shell depends on it; it must be ensured that the display screen can be tightened after it is unfolded, and the display screen can be sufficiently extended when folded; and a pair of small rollers fixed in the adjacent screen edge shells against it, let it It can be positioned and moved freely and without loss during telescoping (see Figure 2 ~ Figure 6 &, 10, 11).

4: The above-mentioned rotating card includes a rotating card body and a rotating card shaft; corresponding to the corners of two adjacent display case shells, the housing groove and bearing seat of the rotating card are placed; the shaft is fixed on the side of a screen case In the bearing seat at the corner; when the screen is in the folded state, the spin card is hidden in the shell groove of the screen and locked; when the screen is in the unfolded state, the spin card is turned 90 ° or 180 ° into the shell of the adjacent screen The slot is clamped to fasten two adjacent displays together (see Figure 5).

5. The cross-section of the slide card is convex or micro-convex; when the screen is in the folded state, the slide card is hidden in the slide slot of a screen and stuck; when the screen is in the unfolded state, push a part of the slide card Into the chute of the adjacent screen (see Figure 6).

6. The cross-section of the above-mentioned folding angle card is an inverted ladder type with a slight oblique on both sides; it is used to have an angle α between adjacent display screens, thereby forming a large screen with a folding plane; After unfolding, the folded corner card is pressed into the slot at the corner of the adjacent screen shell and fixed (see Fig. 7c).

7. Unlike the first foldable display shown above, a large foldable soft display is assembled using only a soft display module. It can be divided into three types:

a. It is an integral continuous folding large soft display composed of at least two folding soft screens, that is, it is assembled by an integral continuous soft base flexible display module (see Figure 9a, Figure 10, each There are no joints between the folded soft screens, and the displayed curve will be continuous :);

b. another folding large soft display screen composed of at least two of the foregoing a large folding soft display screens (there are obvious joint seams between the two large soft screens, see FIG. 11);

c. It consists of an independent soft screen and at least one front soft-folding large soft display (a large soft screen and A more complex folding soft display (see Figure 11) composed of independent soft screens with obvious seams).

The three large folding soft screens listed above are bonded to their corresponding large backplanes by gluing or screws. There are three types of large backplanes:

a. The large back plate is a large bendable plate, that is, the portion of the back plate consolidated with each soft screen is a hard plate, and the portion of the back plate between each soft screen is bendable (see Figures 9a, 9b, 11);

b. The large backplane is a flexible large backplane composed of a single piece of hard backplane that is fixed with each soft screen and is connected with a connector (see Figure 10);

c. A more complex large bendable backplane composed of the aforesaid a large bendable whole plate and a single hard back plate with a connector splicing (see Figure 11).

The above b or c connector is the same bendable connector or / and elastic connector used in the above item 1 (fixed on the surface of the back plate or in the back plate, see Figures 10 and 11); Alternatively, no such connection members are provided between the backplanes, but are independent of each other.

The large back plate and the large soft screen casing are glued or fixed with screws and riveting; when the large back plate and the large soft screen casing are integrated into one, that is, when the large back plate is used to replace the large back plate , The inter-screen connector of each folding soft-screen shell of the large soft screen is also the connector of the large back panel (see Figure 11); the connector of the large soft-screen shell also uses the same Bend connectors, elastic connectors, hinge connectors on the back of the display case, or some combination thereof.

When the soft screens of the folding large soft display screen are unfolded, the screen-to-screen locking mechanism of each soft screen shell still uses the same rotary card, sliding card or / and folding corner card as the above item 1. Beneficial effect

The beneficial effects of applying the present invention are obvious: it will make the folding display possible, thereby solving the demand for large-sized displays such as mobile phones, PDA phones, small instruments and toys, and also making the folding giant display promising become true.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The soft display module or soft display in the figure is represented by the mark 9b; the hard module or the soft module 9b is not distinguished, that is, when both are available, the mark 9 is used.

FIG. 1 is a front view of a large folding display screen 21 when each screen is unfolded. It consists of three display modules 1, 2, 3 assembled by three display modules 9. There are obvious joint seams 5 between the screens. The width of the front side of the screen is 6 and the width of the screen is 10, that is, the margin between the screens is 10, the displayed curve 17 is not smooth, and there are 4 large ladders. The shorter the screen margin 10, the smoother the curve 17 displayed. In the figure: The adjacent screens 1 and 2 are connected by a bendable connecting member 11 (indicated by a dashed line); at the top and bottom of the shells adjacent to the screen 2 and the screen 3, there is a slide lock mechanism between the screens. Slots 62 and 63 (indicated by dashed lines) are used.

Fig. 2 and Fig. 3 are cross-sectional views of a connecting member between two display screens assembled by two display modules 9. Among them: the side of the front shell 6 of the adjacent screen 1 and the screen 2 are connected by a bendable connecting member 11; the back of the shell of the screen 2 and the screen 3 are connected by a hinge 13. The inside of the back shell 7 of the screen 1 and the screen 2 and the back of the display module 9 of the screen 2 and the screen 3 are connected by a long elastic connecting member 12 (the display screen is in a tightened state when expanded) to ensure that the display screen is folded. There is sufficient elongation (see Figure 4); the small roller 12a inside the screen side shell ensures that it can retract and retract without damage; and the fixed end 12b. 2 and 3 correspond to the cross-sectional views taken along lines A-A and B-B in FIG. 1.

FIG. 4 is a cross-sectional view of the large screen 21 composed of the three screens 1, 2, and 3 shown in FIG. 1 after being fully folded and tightened, which is equivalent to the large screen 21 composed of FIGS. 2 and 3 Fully fold again (displays 1 and 2 are folded inward, screen 3 is folded outwards). It can be seen here that there are three kinds of inter-screen connection members such as a bendable connection member 11, two elastic connection members 12, and a hinge 13 on the back of the display case; and the elastic connection member 12 is elongated.

The specific structure of the rotating card of the inter-screen locking mechanism may be different. The spin card used in the embodiment of the present invention is shown in FIG. 5.

Fig. 5a shows a top view of the rotating card at the top 8 of the casing after two adjacent display screens 1 and 2 are deployed. Fighting seams 5.

It can be seen from FIGS. 5a and 5b that the spin card includes a spin card shaft 30 and a spin card body 31; the latter includes a horizontal plate 32, a side plate 33, and a spin card head 35; 50 is fixed inside (see FIG. 5d); the end portion 56 of the bearing seat 50 is a free body with a certain elasticity so as to slightly clamp the spinner shaft 30; the spinner 35 is convex and concave, and the spinner body side plate 33 They are separated by a gap 39 (see FIG. 5c); the neck portion 36 of the spin card is slightly elastic; when the display screen is in a folded state, the spin card body 31 is hidden in the shell groove 52 of the screen 2 (shown by a two-dot chain line mark 40) (The starting position of the spin-card body 31), the recess 38 of the spin-card end 35 slides into the protrusion 58 in the casing groove 52 and is clamped; when the display screen is in the unfolded state, the spin-card body 31 is removed from the shell In the groove 52, rotate 180 counterclockwise to the left. , Turn it into the housing groove 51 of the adjacent display screen 1, and the middle concave part 37 of the rotary chuck 35 slides into the protrusion 57 in the housing groove 51 to be locked.

Fig. 5a is equivalent to the top view of the C-C section in Fig. 1; the dashed line is the bendable connecting member 11 and the elastic connecting member 12 in the shell top 8 (see Fig. 2). Figures 5c and 5d also show the rotating card and the display module 9 (for screen 1 and screen 2 assembly) at the top 8 of the case through the rotating card head 35, the side plate 33, the horizontal plate 32, and the rotating card shaft 30. The relationship of the elastic connector 12 in the back shell Ί.

FIG. 6 illustrates the inter-screen locking mechanism slider 41. Figure 6a is a top view of the sliding card 41 at the top 8 of the casing after two adjacent display screens 2 and 3 are spread out. Reference numeral 13 is a hinge connecting the back shells of the screen 2 and the display 3;

It can be known from Figs. 6a, 6b, and 6c that the cross section of the sliding card 41 is convex or microconvex; the two end surfaces of the convex ribs each have ear-shaped holes 42 (see Fig. 6d) or concave surfaces to facilitate pulling and pushing. The sliding card 41 slides back and forth in adjacent sliding grooves 62 and 63; one side of each end of the rib has a groove 46; and at the distal ends of the adjacent sliding grooves 62 and 63, each has a groove 46 Corresponding and convex micro-elastic sheet 64; when the display screen is in a folded state, the slide card 41 is hidden in the slide slot 63 of the screen 3, and the groove 46 on the right end of the slide card 41 is replaced by the micro-elastic sheet 64 on the right end of the slide slot 63. Stuck (the two-dot chain line mark 40 marks the starting limit position of the slide card 41); when the display screen is in an expanded state, push the left end portion of the slide card 41 into the slide slot 62 of the adjacent screen 2, The groove 46 at the left end of the card 41 is caught by the micro-elastic sheet 64 of the sliding slot 62.

Fig. 6a corresponds to the top view of the G-G section in Fig. 1 (see Fig. 3). 6c and 6d also show the relationship between the slide card 41 and the display module 9 and the elastic connecting member 12.

Fig. 7a is a giant screen 21 bent inward and composed of five screens 9; There is an angle between adjacent displays. The screens are not numbered here. Figure 7b is an enlarged schematic view at P; it shows: Adjacent screens 9 are connected by bendable connectors 11 in the side 6 of the front shell; the back shell 7 is fixed with bolts 14; the front shell of the display screen is narrow, and the back shell 7 is wide;

Fig. 7c shows the folding corner card 47 for the inter-screen locking mechanism at the mark P at the top 8 of the case. Figure 7d shows that the cross-section is an inverted ladder with slightly inclined sides. After the two adjacent display screens 9 are assembled together, the inter-screen folding corner card 47 is pressed into the card slot 48 at the corner of the adjacent screen shell, and fixed with the coupling screw 49.

Obviously, for giant TV wall screens, it can either be folded and transported after being assembled together in the factory, and then unfolded after being used at the place of use; it can also be transported separately after being transported to the place of use. When not in use, it can even be fixed by welding instead of bolts 14.

FIG. 8 is an enlarged schematic diagram at a mark P similar to FIG. 7b. The only difference is the giant screen 21 protruding outwards. Screen margin 10.

Figs. 9a and 9b are cross-sectional views of a whole continuous folding large soft display screen 22 when it is not fully folded or fully folded (Fig. 9b). It consists of soft 1, screen 2 (screen 3 in Figure 9b). The large soft screen 22 is an integral continuous large folding soft display module 9b, which is fixed to a large back plate 27 that can be bent by gluing or screws; the back plate portion 27a between the flexible screens is flexible. Bent.

Between the soft screens of the large soft screen 22, there are naturally no joints 5; but after the large soft screen 22 is bent, the bending recess 25 will appear as a line, called a folding seam, and the mark 5 is still used. Marking (In Figures 12 to 18 of the following embodiment, the bending concavities and convexities 25 of the large soft screen will be marked with only the folding seam mark 5).

Fig. 10 is a cross-sectional view similar to that shown in Fig. 9a. The difference is that the large backplane is made up of a single backplane 28 fixed to each soft display module 9b, and connected by two flexible connecting members 12 of different lengths. The end 12b is fixed in the back plate 28; the small roller 12a is fixed in the side of the adjacent back plate 28.

FIG. 11 is an overall complex folding large soft display screen 23. It consists of five soft screens, that is, two large soft screens 22 (she soft screens 1, 2 and 3, 4) and an independent soft display module 9b. The soft screens 1, 2, and 3 are respectively fixed with a single back plate 28; the soft screen 4 and the independent soft rhino 9b are fixed with a large whole plate 27. Therefore, the flexible large back plate 29 of the large soft screen 23 is composed of three back plates 28 and a large complete plate 27. However, it can be seen from the figure that the large back plate 29 and the outer shell of the large soft screen 23 have been combined into one, that is, the soft screens 1 and 2, and the screens 3 and 4 are connected by the elastic connecting members 12, respectively; the soft screen 2 It is connected with 3 by an elastic connecting member 12 and a bendable connecting member 11; at this time, the bendable portion 27a of the large plate 27 must be a particularly high-performance material. Obviously, when the display screens are deployed, there will be obvious seams between the two large soft screens 22 and between the screen 4 and the soft display module 9b. FIG. 12 to FIG. 18 are application examples of the folding large display screen 21 or the folding large soft display screen 22 or 23 spliced by the coupling device of the present invention in a mobile phone computer and the like.
