The present invention relates to a multi-surface display device capable of obtaining

  2. Description of the Related Art Conventionally, a multi-screen display device that has a plurality of display panels and can display information on each display panel has been proposed.

  As an example of such a conventional multi-display device, there is a foldable mobile phone including two housings that are connected to each other through a hinge portion so as to be opened and closed.

  The first casing of the mobile phone has a hexagonal cross-sectional shape, and a main display is provided on the inner surface when the mobile phone is folded, and the main display is provided. Sub-displays are respectively arranged on the surfaces connected to the sides of the surfaces at obtuse angles.

  In addition, a speaker and an antenna are disposed in the first casing, and a wireless transmission / reception unit connected to the antenna is incorporated.

  And in the mobile phone as an example of the conventional multi-surface display device having the above-described configuration, as the display of each display, for example, the information of the other party is displayed on the main display at the time of a call, the call time on one sub-display, The remaining sub-display shows the remaining battery power, and when checking the main display, the display of each sub-display arranged at an obtuse angle with respect to the main display can be checked at the same time. (For example, refer to Patent Document 1).

Japanese Patent Application Laid-Open No. 2004-48781

  However, in the mobile phone as an example of the conventional multi-display device described above, a main display is disposed on one surface of a casing having a hexagonal cross section, and the side of the surface on which the main display is disposed. The sub-displays are arranged on the surfaces connected to each other at an obtuse angle, and it is necessary to provide a gap between the displays.

  In addition, the mobile phone as an example of the above-described conventional multi-display device displays different information on each display. For example, if one display is formed by all the displays, a gap between the displays is displayed. The display was strongly divided, and the appearance was not good.

  Accordingly, the present invention provides a multi-panel display device configured by connecting a plurality of display panels at a predetermined angle to reduce a non-display area between a pair of adjacent display panels and to continuously display on each display panel.

  And the liquid crystal display panel 6 as a sub display of this embodiment is the said rear board | substrate in one of the sealing material sticking area | regions 6a and 6b of a both-ends part (in this embodiment sealing material sticking area | region 6b). The front substrate 18 and the rear substrate 19 are partially cut away at an angle of 45 ° from the side 19.

  Then, the cut end surface of the sealing material attaching region 4b of the liquid crystal display panel 4 and the cut end surface of the sealing material attaching region 5a of the liquid crystal display panel 5 are brought into contact with each other, and the liquid crystal display panel 4 By bringing the cut end face of the sealing material attaching region 4a into contact with the cut end face of the sealing material attaching region 6b of the liquid crystal display panel 6, as shown in FIG. 5 and 6 are connected in a U-shape.

  Therefore, the liquid crystal display panel 4 is positioned on the upper surface 2b of the casing 2, the liquid crystal display panel 5 is positioned on the side surface 2c of the casing 2, and the liquid crystal display panel 6 is positioned on the side surface 2d of the casing 2. By disposing, the multi-display device 1 of the present embodiment is formed.

  According to the multi-surface display device 1 of the present embodiment having the above-described configuration, the liquid crystal display panels 4, 5, 6 disposed on the adjacent upper surface 2 b, side surface 2 c, and side surface 2 d of the housing 2 are respectively Since each side edge is inclined at an angle of 45 ° by cutting off portions of the sealing material attachment regions 4a, 4b, 5a, 6b at an angle of 45 °, the respective sealing material attachment regions 4a, In 4b, 5a and 6b, the liquid crystal display panels 4, 5 and 6 can be connected in a U-shape.

  The liquid crystal display panels 4, 5 and 6 are connected to each other in the sealing material adhering regions 4a, 4b, 5a and 6b, so that there is a gap between the liquid crystal display panels 4 and 5 and between the liquid crystal display panels 4 and 6. The (non-display area) becomes very small with only the width of each sealing material attaching area 4a, 4b, 5a, 6b, and the liquid crystal display panels 4, 5, 6 can be scrolled to display one display. A very good display can be obtained.

  In the present embodiment, the multi-display device 1 has a configuration in which liquid crystal display panels 4, 5, and 6 are connected to a mobile phone as a sub display, and the display on each of the liquid crystal display panels 4, 5, and 6 is, for example, Scrolling display of incoming call number display and text information such as news and weather forecasts.

  Moreover, in this embodiment, each sealing material sticking area | region 4a, 4b, 5a, 6b of each liquid crystal display panel 4,5,6 is cut off at an angle of 45 degrees, but it is not limited to this. In the case where the three liquid crystal display panels 4, 5, 6 are connected in a U-shape, the total inclination angle of the pair of end faces to be connected may be 90 °. For example, the sealing material adhering regions 4a and 4b of the liquid crystal display panel 4 are cut at an angle of 60 ° from the rear substrate 13 side so that the inclination angle of the end surfaces of the both side ends of the liquid crystal display panel 4 is 30 °. The sealing material adhering region 5a of the panel 5 and the sealing material adhering region 6b of the liquid crystal display panel 6 are cut away at an angle of 30 ° from the side of the rear substrates 16 and 19, respectively. Even when the inclination angle of the end face is set to 60 °, the liquid crystal display panels 4, 5, 6 can be connected in a U-shape. However, when part of the side end of each liquid crystal display panel is cut off, part of the sealing material 9 that adheres the pair of substrates constituting the liquid crystal display panel is also cut off at the same time. Since the sticking property of the substrate is lowered, it is preferable that the inclination angle of the opposite end surfaces of the pair of liquid crystal display panels connected to each other is approximately two minutes of the angle connecting the pair of liquid crystal display panels. It is better to cut it so that the angle is 1.

  Next, as shown in FIG. 8, the multi-display device 31 according to another embodiment of the present invention includes five liquid crystal display panels 32, 33, 34, 35, and 36, and the liquid crystal display panels 32, 33, 34, 35, and 36 are connected at an angle of 135 °. At this time, as an example of the inclination angle of the cut end surface of each liquid crystal display panel 32, 33, 34, 35, 36, the sealing material attaching region 32a of the liquid crystal display panel 32 is 65 °, and the liquid crystal display Sealing material attaching regions 33a and 33b of the panel 33 are 70 °, sealing material attaching regions 34a and 34b of the liquid crystal display panel 34 are 65 °, sealing material attaching regions 35a and 35b of the liquid crystal display panel 35 are 70 °, and liquid crystal A sealing material attaching region 36b of the display panel 36 is set to 65 °.

  Thus, a plurality of liquid crystal display panels can be connected to a polygonal surface by cutting the side end portions of each liquid crystal display panel at various angles in the sealing material attaching region. Furthermore, since each liquid crystal display panel is connected in the sealing material adhering region, a good display can be obtained by reducing the gap between the liquid crystal display panels.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed. For example, in the present embodiment, the display panel is a liquid crystal display panel, but may be an organic EL display panel or a plasma display panel.
