Description

  The present invention relates to a display device, and more particularly to a display device including a flexible display panel.

  For example, in a liquid crystal display panel, a pair of substrates arranged to face each other with a liquid crystal interposed therebetween is used as an envelope. The liquid crystal is sealed with an annular sealing material formed between a pair of substrates, and a large number of pixels including the liquid crystal as one constituent element are formed in a region surrounded by the sealing material.

  In recent years, a pair of substrates constituting the envelope of the liquid crystal display panel has been known to be formed of a flexible material such as a resin instead of glass, for example. As a result, the liquid crystal display panel can be configured to be lightweight and not damaged even when dropped.

  The liquid crystal display panel itself can be bent, that is, can be made flexible (hereinafter, such a display panel may be referred to as a flexible display panel), for example, as shown in Patent Document 1 below, a flexible display panel As shown in Japanese Patent Application Laid-Open No. 2004-26883, a display device is known that can be folded, or a display device that is configured so that a flexible display panel can be disposed so as to be wound around a device main body. Such a liquid crystal display panel is used in an expanded state when observing the liquid crystal display panel, and can be folded and housed while the liquid crystal display panel is not being observed.

  Embodiments of the present invention will be described with reference to the drawings. In each drawing and each example, the same or similar components are denoted by the same reference numerals and description thereof is omitted.

  FIGS. 1A and 1B are configuration diagrams showing Embodiment 1 of the display device of the present invention. FIG. 1A is a perspective view showing a state in which a flexible display panel is expanded, and FIG. 1B is a cross-sectional view showing a state in which the flexible display panel is housed.

  In FIG. 1A, the display device is composed of a device main body MC and a display unit DP whose one end is rotatably connected to the device main body MC.

  The device body MC has a box shape, and includes a control circuit (not shown) for driving each pixel of the flexible display panel FPL described later, a power supply (not shown) for supplying power to the control circuit, and the like. Is built-in. In the device main body MC, one surface is the first surface SF1, the surface facing the first surface is the second surface, and one of the surfaces between the first surface and the second surface is the first surface. When the side surface SD1 and the surface opposite to the first side surface are the second side surface SD2, the display unit DP is a rotation mechanism (not shown) at the boundary between the first surface SF1 and the first side surface SD1 of the precursor device body MC. ) Is attached through. Further, the device main body MC has a direction parallel to the connection end side of the display portion DP to the device main body MC (the y direction in the figure: the first direction in this specification) on the first side surface SD1 and the second side surface SD2. It may be referred to as a convex surface having a top portion. In this case, the first side wall surface SD1 may be a flat surface instead of the convex surface as described above.

  The display unit DP includes a first casing FR1, a second casing FR2, a third casing FR3, which are sequentially connected in the x direction in the drawing from the device main body MC side, and the first casing. The flexible display panel DP is arranged on the FR1, the second casing FR2, and the third casing FR3.

  As shown in FIG. 1A, the first housing FR1, the second housing FR2, and the third housing FR3 have substantially the same surface as the surface including the first surface of the device body MC. It is possible to take a state that is positioned in. A rotation mechanism that connects the device body MC and the first housing FR1, a rotation mechanism that connects the first housing FR1 and the second housing FR2, and a rotation that connects the second housing FR2 and the third housing FR3. In the mechanism, the state shown in FIG. 1A can be easily created by providing means for restricting the rotation of the housings adjacent to each other. In this case, the display surface of the flexible display panel DP arranged on the first housing FR1, the second housing FR2, and the third housing FR3 is flattened and can be observed. The flexible display panel PNL is composed of, for example, a liquid crystal display panel whose substrate is made of resin or the like, and one end on the side of the device main body MC is electrically connected to a control circuit built in the device main body MC through the flexible substrate FLB, for example. It has become. Here, the flexible display panel PNL formed of a liquid crystal display panel is configured by a reflection type that displays using external light such as sunlight, and does not include a so-called backlight. Yes.

  In addition, the first casing FR1 and the third casing FR3 each have a flat plate shape, whereas the second casing FR2 has a surface on the side opposite to the flexible display panel PNL, y in the figure. It has a convex surface with a bottom along the direction. In other words, the first casing FR1, the second casing FR2, and the third casing FR3 are each made up of the first surface SF1, the second side surface SD2, and the second surface of the device main body MC as shown in FIG. By arranging the display unit PD so as to face the SF2, the display unit PD can be arranged so as to be wound around the device main body MC. At this time, the second casing FR2 is configured as described above so as to correspond to the convex surface of the second side surface SD2. It is configured as a concave surface. That is, the second housing FR2 is a concave surface having a bottom portion along the y direction in the drawing on the surface facing the flexible display panel PNL.

  Accordingly, the flexible display panel PNL is disposed between the device main body MC and the first casing FR1, the second casing FR2, and the third casing FR3, and can be in a state of being accommodated in the display device. In this case, the flexible display panel PNL is curved along the convex surface of the second side surface SD2 and the concave surface of the second housing FR2 at a portion sandwiched between the second side surface SD2 of the device main body MC and the second housing FR2. Will come to be. Since the above-described curve of the flexible display panel PNL is a concave surface on the observation surface of the flexible display panel PNL, in this embodiment, the observation surface is configured to be convex at each of both ends of the flexible display panel PNL. ing. As a result, the adverse effects caused by the bending at the central portion of the flexible display panel PNL are offset by the bending at each of both ends.

  As shown in a dotted frame A in FIG. 1B, the end of the first housing FR1 facing the flexible display panel PNL on the side of the device main body MC side, y in FIG. 1A. A slope SLP1 extending in a direction corresponding to the direction is formed. The inclined surface SLP1 is formed as an inclined surface whose height decreases as it approaches the device main body MC, and the end of the flexible display panel PNL is fixed on the inclined surface. As a result, one end of the flexible display panel PNL on the first housing FR1 is formed with a convex surface having a top portion along the direction corresponding to the y direction in FIG. Become so. Similarly, as shown in a dotted line frame B in FIG. 1B, on the edge of the third housing FR3 facing the flexible display panel PNL at the end away from the device main body MC, as shown in FIG. A slope SLP2 extending in a direction corresponding to the y direction in the figure is formed. The inclined surface SLP2 is formed as an inclined surface whose height decreases as the distance from the device body MC increases, and the end of the flexible display panel PNL is fixed on the inclined surface. As a result, the other end side of the flexible display panel PNL on the third housing FR3 is formed with a convex surface having a top portion along the direction corresponding to the y direction in FIG. It becomes like this.

  Even if the display device configured in this way has to bend the flexible display panel PNL so as to be concave on one surface, it becomes convex at different locations on the same one surface. Since it is configured to be bent, a negative effect caused by one curve can be offset by the other curve, and a negative effect caused by bending of the flexible display panel PNL can be avoided.

  FIG. 2 is a block diagram showing Embodiment 2 of the display device of the present invention. FIG. 2 shows a cross-sectional view of a flexible display panel PNL formed of the liquid crystal display panel shown in FIG.

In FIG. 2, the flexible display panel PNL includes a pair of substrates SUB1 and SUB2 disposed opposite to each other with the liquid crystal LC interposed therebetween, and the liquid crystal LC is an annular sealing material SL formed between the substrates SUB1 and SUB2. In a region surrounded by the sealing material SL, a large number of pixels (not shown) including the liquid crystal as one constituent element are formed. As is apparent from the description of the first embodiment, the flexible display panel PNL configured as described above has a curved portion BD at the central portion and a location close to each end side when stored. For this reason, a groove DN for reducing the thickness of the substrate is formed in each of the substrates SUB1 and SUB2 at the curved portion BD. Thus, the flexible display panel PNL is easily bent at a predetermined location. The above-described groove DN can be formed in each substrate SUB1SUB2 by selective etching, for example.

  The second embodiment is applied to the flexible display panel PNL shown in the first embodiment, but can also be applied to the flexible display panel PNL shown in the third to sixth embodiments described later.

  FIGS. 3A and 3B are configuration diagrams showing Embodiment 3 of the display device of the present invention, and correspond to FIGS. 1A and 1B, respectively.

  In FIG. 3A, the display device is composed of a device main body MC and a flexible display panel PNL connected to the device main body MC.

  The device body MC has a box shape, and includes a control circuit for driving each pixel of the flexible display panel FPL, a power source for supplying power to the control circuit, and the like. In the device main body MC, as in the case of FIG. 1A, one surface thereof is the first surface SF1, the surface opposite to the first surface SF1 is the second surface SF2, and the first surface SF1 and the second surface. In the case where one of the surfaces between the first side surface SD1 and the second side surface SD2 is a surface facing the first side surface SD1, the first side surface SD1 and the second side surface SD2 are respectively shown in FIG. It is a convex surface having a top along the middle y direction. In addition, the y direction in the drawing is matched with the direction along one end side connected to the first device body MC of the flexible display panel PNL. Further, a protrusion PJ extending in the y direction in the figure is formed at the center of the first surface SF. The protruding portion PJ has a pair of side wall surfaces SDW1 and SDW2 formed along the extending direction (y direction in the figure), and these side wall surfaces SDW1 and SDW2 respectively have bottom portions along the y direction. It has a concave surface.

  One end of the flexible display panel PNL is connected to the top of the protrusion PJ via a flexible substrate FLB, and one side wall surface SDW1 of the protrusion PJ, and further, the side of the device main body MC on the side wall surface SDW1 side. Arranged in a state extending in the x direction in the drawing along the first surface SF. In this case, the flexible display panel PNL can be arranged in a planar shape, and the display surface of the flexible display panel PNL can be observed.

  In addition, the flexible display panel PNL is arranged so as to be wound around the device main body MC, as shown in FIG. 3 (b), and the other end portion (the end connected to the device main body MC) is stored. The end side opposite to the side) is fixed in contact with the side wall surface SDW2 of the projection PJ.

  In this case, the flexible display panel PNL is curved so that the display surface side is a convex surface at a portion facing the first side surface SD1 and the first side surface SD2 of the device main body MC. However, one end side of the flexible display panel PNL connected to the device body MC and the other end side opposite to the one end side are in contact with the side wall surfaces SDW1 and SDW2 of the projection PJ, respectively, and the display surface side is A concave curve is made.

  Therefore, the display device configured in this way can also avoid the adverse effects caused by the bending of the flexible display panel PNL.

FIGS. 4A and 4B are configuration diagrams showing Embodiment 4 of the display device of the present invention, and correspond to FIGS. 3A and 3B, respectively.

  In FIG. 4, the configuration different from the case of FIG. 3 is that the projection PJ of the device body MC is formed on the second side surface SD2.

  Then, the side walls SDW1 and SDW2 of the projection PJ are formed with a concave surface having a bottom along the y direction in the figure, and one end side of the flexible display panel PNL is connected to the top of the projection PJ through the flexible substrate FLB. This is the same as in the case of FIG.

  When configured in this way, as shown in FIG. 3B, which is a side view showing a state in which the flexible display panel PNL is housed in the device main body MC, the flexible display panel PNL is the first side surface SD1 of the device main body MC. In the portion facing the second side surface SD2, the display surface side is curved so as to be convex. However, one end side of the flexible display panel PNL connected to the device body MC and the other end side opposite to the one end side are in contact with the side wall surfaces SDW1 and SDW2 of the projection PJ, respectively, and the display surface side is A concave curve is made.

  Therefore, the display device configured in this way can also avoid the adverse effects caused by the bending of the flexible display panel PNL.

Has been. One end side of the flexible display panel PNL is connected to the side surface of the first device body MC1 via the flexible substrate FLB. Accordingly, the flexible display panel PNL is rotatably connected to the first device body MC1 by bending the flexible substrate FLB. The first device body MC2 may or may not include a control circuit.

  Here, in the first device main body MC1, one surface is the first surface SF1, the surface facing the first surface is the second surface SF2, and the side surface to which the flexible display panel PNL is connected is the first side surface SD1. When the surface facing the first side surface SD1 is the second side surface SD2, the first side surface SD1 is, for example, a flat surface, but the second side surface SD2 is a convex surface having a top along the y direction in the figure. It has become. In addition, the y direction in the drawing is matched with the direction along one end side connected to the first device body MC1 of the flexible display panel PNL.

  In the second device main body MC2, a surface for fixing the flexible display panel PNL is a first surface SF1 ′, a surface facing the first surface SF1 ′ is a second surface SF2 ′, and the first surface SF1 ′. When the side surface on the other end side of the flexible display panel PNL is the first side surface SD1 ′ and the surface facing the first side surface SD1 ′ is the second side surface SD1 ′ among the surfaces between the second surface SF2 ′. The first side surface SD1 ′ is a flat surface, but the second side surface SD2 ′ is a convex surface having a top portion along the y direction in the drawing.

  The display device configured as described above can accommodate the flexible display panel PNL as shown in FIG. That is, for example, as shown in FIG. 5A, the first device main body MC1 is rotated in the direction of the arrow in the drawing, and the observation surface of the flexible display panel PNL is the first surface SF1, the second surface of the first device main body MC1. The side surface SD2 is in contact with the second surface SF2, and the surface opposite to the observation surface of the flexible display panel is in contact with the second side surface SD2 ′ and the second surface SF2 ′ of the second device body MC2, and the second surface SF2 ′. The device main body MC2 can be placed on the first device main body MC1.

  As is apparent from FIG. 5B, the display device configured in this way is bent so that the observation surface of the flexible display panel PNL is a concave surface by the second side surface SD2 of the first device body MC1. Even in this case, the second device main body MC2 is curved to be concave on the surface opposite to the observation surface by the second side surface SD2 ′. Therefore, the adverse effect due to one curve is offset by the other curve, and the adverse effect caused by bending of the flexible display panel PNL can be avoided.

  In Example 5, when the flexible display panel PNL is housed, a part of the observation surface of the flexible display panel PNL (indicated by symbol AR in the figure) is exposed on the second device body MC2 as shown in FIG. It becomes the composition which becomes. For this reason, you may make it comprise so that display, such as a time display, may be performed in this part.

  FIGS. 6A and 6B are configuration diagrams showing Embodiment 6 of the display device of the present invention, and correspond to FIGS. 1A and 1B, respectively.

  6A, the display device includes a device main body MC, a flexible display panel PNL having one end connected to the device main body MC, and a cover CVR rotatably attached to the device main body MC. ing.

  The device body MC has a box shape, and includes a control circuit (not shown) for driving each pixel of the flexible display panel FPL, a power source (not shown) for supplying power to the control circuit, and the like. ing.

  In the device body MC, one surface is the first surface SF1, the surface facing the first surface SF1 is the second surface SF2, and one of the surfaces between the first surface SF1 and the second surface SF2 is one. When one surface is a first side surface SD1 and a surface opposite to the first side surface SD1 is a second side surface SD2, the first surface SF1 and the second surface SF2 each have a bottom along the y direction in the figure. A concave surface is formed, and the second side surface SD2 is formed with a convex surface having a top portion in the y direction in the figure.

  The flexible display panel PNL is connected to a boundary portion between the first surface SF1 and the first side surface SD1 of the device main body MC via a flexible substrate FLB at one end side. The flexible display panel PNL is arranged in a flat plate shape so as to protrude from the device main body MC on the device main body MC so that the display can be observed.

  The cover CVR is rotatably connected to a boundary portion between the first side surface SD1 and the second surface SF2 of the device main body MC at one end side thereof. The cover CVR includes a first cover part CV1, a second cover part CV2, and a third cover part CV3 that are sequentially connected in a rotatable manner from the device main body MC side. The second cover CV2 can be disposed to face the first surface SF1, the second side surface SD2, and the second surface SF2, and the second cover CV2 has a concave surface corresponding to the convex surface of the second side surface SF2.

  The display device configured as described above can accommodate the flexible display panel PNL as shown in FIG. That is, the flexible display panel PNL is arranged by winding the device body MC along the first surface SF1, the second side surface SD2, and the second surface SF2 of the device body MC. The cover CVR is configured such that the first cover portion CV1, the second cover portion CV2, and the third cover portion CV3 face the first surface SF1, the second side surface SD2, and the second surface SF2 of the device body MC, respectively.

  In this case, the flexible display panel PNL is between the first surface SRF1 of the device body MC and the first cover portion CV1 of the cover CVR and between the second surface SRF2 of the device body MC and the second cover portion CV2 of the cover CVR. The observation surface is curved so as to be concave.

  For this reason, even if the flexible display panel PNL is curved so that the observation surface becomes a convex surface between the second side surface SD2 of the device main body MC and the second cover portion CV2 of the cover CVR, the above-described case may occur. Thus, by forming a concave curved surface on the observation surface, it is possible to make a configuration in which the adverse effect due to one curvature is offset by the other curvature, and the adverse effect due to bending of the flexible display panel PNL can be avoided.

  The flexible display panel PNL in the above-described embodiment is described by taking a liquid crystal display panel as an example. However, for example, even in an organic EL display panel, a substrate on which an organic EL element is formed and a substrate for sealing the organic EL element are arranged to face each other, and these substrates have flexibility. Similar problems arise in some cases. Therefore, the present invention can also be applied when an organic EL display panel is used as the flexible display panel PNL. Further, the present invention can also be applied when electronic paper is used for the same reason.
