Description

  The present invention relates to a display device, and more particularly to a display device using a plurality of flexible display displays.

  In recent years, a display device using a flat display device such as a liquid crystal display (LCD) or a plasma display panel (PDP) is thinner and lighter than a cathode ray tube (CRT) of the same size. Public display boards and monitor display devices in conference spaces are becoming popular.

However, as the demand for thin and large-screen display advances, the space as a display area cannot be ignored even if it is thin. In response to this type of demand, many methods for projecting onto a large screen using a projection type projector or the like have been proposed.
When using the above-mentioned projection type projectors, there are various obstacles and inconveniences when projecting in a large size, such as the projector installation space, the distance to enlarge and project on the screen, and obstacles can not be placed between them. Has occurred.

On the other hand, a display device using a flat display device having a relatively small display size is widely used as a display device for various portable devices such as a notebook PC, a PDA, a mobile phone, a car navigation system, and an electronic book player. ing. A demand for this type of portable device is that it is small and light and can be easily carried, and a form that is easy to store in a space-saving manner is desired.
A display device has been proposed that solves such a form that can be stored in a space-saving manner as much as possible during carrying (see, for example, Patent Documents 1 to 3).
In addition, notebook information processing devices and display devices that carry electronic books have been proposed (see, for example, Patent Documents 4 to 6).
The inventions described in Patent Documents 1 to 3 use a flexible display as a display panel. In Patent Documents 1 and 2, the display can be stored on a roll.
The inventions described in Patent Documents 4 to 6 use a plurality of flat displays and paper-like media, and can be handled with the same feeling as a paper book while turning pages.

Japanese Patent Laid-Open No. 11-272205 JP 2002-182582 A JP 2003-43955 A JP-A-6-274458 JP 2003-58081 A JP 2003-58544 A

By the way, the proposals described in Patent Documents 1 and 2 are suitable for displaying a single screen, but when a plurality of screens, particularly screens having different input formats, are input, for example, broadcast signals and document information, When you want to see map information at the same time, every time multiple signals are received, the receiver side converts the format to synthesize multiple screens, or enlarge / reduce processing to display multiple screens on one display screen. There is a problem that the processing circuit becomes complicated.
There is also a problem that if the number of screens to be displayed at the same time increases, such as when viewing a plurality of document screens at the same time, the display area per screen becomes small and difficult to see. Further, when a plurality of sets of display devices are used to view a plurality of screens, not only portability and convenience are impaired, but also new problems such as an increase in installation location occur.

In the proposals described in Patent Documents 3 to 6, although depending on the display area per page, if the display area per page is made as large as possible to make it easy to see, the device of at least the size of the display area is used. Therefore, there may be a problem that it becomes unsuitable for portability.
Moreover, there is a possibility that the usage pattern is limited to displaying book information. Further, when the user wants to view information on three or more screens at the same time, he / she turns the page or looks at two spread pages.

  The present invention has been made in view of the above points, and an object thereof is to provide a display device that can improve portability, operability, and convenience by using a plurality of flexible display displays. .

In order to solve the above-mentioned problems, the present invention comprises means described in 1) to 2) described below.
That is,
1) A display device in which the entire display of 1 is composed of a plurality of flexible display display units,
A storage unit for storing the display unit;
One end is rotatably fixed inside the storage unit, and a display control unit that performs display control of all the display display units pulled out of the storage unit;
Display area detecting means for detecting the pull-out amount of all the display display parts pulled out inside the storage part;
Enlargement / reduction display means for performing enlargement / reduction display of the display signal in field units so that the display area detected by the display area detection means is maximized;
A display device comprising:
2) The display device according to 1), further comprising a signal processing circuit for simultaneously displaying input display signals having different input formats in the maximum display area of each display display unit.

According to the “display device” of the present invention, it is possible to store all of the plurality of display displays connected to the control unit inside the display device storage unit, so that the display area of each display display can be set large. In addition, since the display device can be reduced in size and weight, a mobile terminal excellent in portability and convenience can be realized.
In addition, since a plurality of display displays are prepared, it is possible to simultaneously view a plurality of images having different input formats such as broadcast signals, document information, and map information, and there is no need to synthesize each image and convert the format. Therefore, the processing circuit is simplified, and high-quality images can be displayed on a large display screen that has been subjected to optimum image processing.
Furthermore, since the display screen can be displayed in a drawer state according to the installation location, a general display device having excellent installation properties can be realized.

  Hereinafter, the best mode for carrying out the invention of the display device according to the present invention will be described with reference to preferred embodiments.

  FIG. 1 is a schematic configuration diagram of a display device applied to the first embodiment (when the display is stored). As shown in the figure, the display device 100 shows a state where three display displays 120 having flexible flexibility are accommodated. The display device 100 includes a display control unit and signal processing unit 110 for each of the display displays 120, and a display drawer unit 130 for pulling out each display display 120. The display control unit and signal processing unit 110 is configured to rotate within the display device 100 and to wind up the three display displays 120 in common. The display display may be monochrome or color.

  FIG. 2 shows a state in which the display screens of the three display displays 120 in the display device 100 are pulled out. The book data may be taken in by inserting a memory card, a disk or a card-like recording medium into the display device 100, or may be in a form in which the data transmitted by the communication device is downloaded and taken in.

By adopting the configuration of the display device 100 as shown in FIGS. 1 and 2, when the display display 120 is housed, it can be made smaller than a conventional spread electronic book. In addition, since the screen size when the display display 120 is pulled out can be increased, the characters of the book data can be displayed in a large size, so that the screen can be easily viewed.
Furthermore, since a plurality of display displays are used, data of a plurality of pages can be displayed at the same time, which is convenient when comparing with other pages.
When displaying multiple pages, it is not always necessary to display the pages in page order. The reference page is always displayed, and the page to be referenced apart from the reference page may be displayed on the display display of the next page. .

  FIG. 3 is a schematic configuration diagram of the display device applied to the second embodiment (when the display is stored). As shown in the figure, a state is shown in which three display displays 121a, 121b, and 121c having flexible flexibility are stretched in the display device 101. When the three display displays 121a, 121b, and 121c are completely stored, the size of the display device 101 alone is obtained.

  The display device 101 includes display control units and signal processing units 111a, 111b, and 111c of display displays 121a, 121b, and 121c, and display drawer units 131a, 131b, and 131c for pulling out the three display displays 121a, 121b, and 121c, respectively. And a signal processing unit 140. The display control unit and the signal processing units 111a, 111b, and 111c are configured to rotate in the display device 101 and wind up the three display displays 121a, 121b, and 121c, respectively. The display display may be monochrome or color.

  FIG. 4 shows a state in which the display screens of the three display displays 121a, 121b, and 121c in the display device 101 of FIG. 3 are pulled out, and shows a form in an actual usage state. In the figure, the lengths of the three display displays are different from each other, but can be extended to the same length. The signal processing unit 140 and the signal input unit 150 may be connected by a signal cable or may transmit display data wirelessly.

  This figure assumes a usage pattern such as a conventional projector screen. The conventional projector screen was only intended for projecting a signal sent from the projector onto the screen. However, in the display device of the present invention, the screen itself is a self-luminous screen, and a plurality of screens can be displayed. Since a screen is provided, it is possible to simultaneously display a plurality of display signals and projection screens having different input formats, which has been impossible in the past, in a nearby place.

  In the figure, a display screen that is divided into upper and lower parts is shown. However, as an actual usage example, a usage form such as simultaneously displaying a presentation screen for three people is conceivable. In the past, presentations were made by connecting a personal computer to the projector for each person, but in the case of the display device 101, all personal computer outputs for three persons are connected to the signal input unit 150, and three display screens are displayed. Can be displayed simultaneously on the top. This is effective when you want to view multiple people's materials at the same time, such as in a panel discussion. In addition to a personal computer screen, a television broadcast such as a digital broadcast, a playback screen of a recording medium such as communication information, video, and DVD can be displayed simultaneously. You may use the surface which is not displayed as a screen which projects partially data, such as OHP. In that case, the surface used as the screen to be projected is operated so as to be automatically in a non-display (power OFF) state.

  As shown in the figure, when the display is divided into three upper and lower divided areas, the display display 121a has the upper two-third area stored in the display device 101 and the lower one-third as a displayable area. It has become. In the display display 121b, the upper third region is stored in the display device 101 and the lower second third is a displayable region, and the display display 121c is stored in the display device 101. Since all are drawn out, all are displayable areas.

  However, regarding the display display 121b, it is necessary to display in the area below the part of the displayable area that overlaps the display display 121a. Moreover, regarding the display display 121c, it is necessary to display in a region below the portion that overlaps the display display 121b in the displayable region.

  In this way, when the display is divided into three upper and lower regions and simultaneously displayed, how long or how many other display devices overlap in the displayable region as viewed from the display side. , And the display control unit and the signal processing units 111a, 111b, and 111c process the display signal so as to display in an area where other display devices do not overlap.

  In addition, when the display surfaces of the display displays 121a, 121b, and 121c can be displayed on both front and back surfaces, are there other display displays on the front side of the display surface on the front side display surface and the back side display surface, respectively? It is recommended that the display control unit and the signal processing units 111a, 111b, and 111c process the enlargement / reduction of the display signal so as to detect whether or not to display in a non-overlapping region.

  As for detection of whether or not they overlap, for example, as shown in the display area detection means 160a, 160b, 160c, detection sensors are provided in the left and right non-display areas with respect to both sides of the display display, and other display displays. The distance sensor which detects whether it has overlapped by sensing the distance of is used. For example, this detection is performed at fixed time intervals such as for each field, and each time the displayable area changes, the enlargement / reduction processing is performed so that the maximum size is displayed in the displayable area each time. I will go.

  Although it is the above-mentioned detection sensor, in order to detect the display display part pulled out, you may use the optical sensor which detects the external light which hits the display display part pulled out. Further, a pressure sensor or a contact sensor may be used to detect the overlap of the display display portions.

  By adopting a configuration such as the display device 101, the display displays 121a, 121b, and 121c can be reduced in size when stored, and the space when the display device is not used can be effectively utilized by being provided on the ceiling or the like. When the display device is installed on the ceiling and used, the display displays 121a, 121b, and 121c can be automatically pulled out, or the lengths of the display displays 121a, 121b, and 121c can be automatically pulled out even when they are pulled out differently. You may be able to pull it out with.

  In addition, since the screen size in the direction in which the display displays 121a, 121b, and 121c are pulled out can be set to any length, when the user wants to view a plurality of materials at the same time, the display length is adjusted on each display display as shown in FIG. Multi-screen display. In this case, even if there are a plurality of images having different input formats, it is not necessary to perform format conversion when combining the images, so that the processing circuit does not have to be complicated and optimum image processing is performed. Images can be displayed simultaneously.

In the above-described first embodiment, the display is divided into the upper and lower divided areas, and the display is described. However, the display display may be other number of display displays. Further, the display display may not be drawn from the entire width of the display device 103.
FIG. 5 is a schematic configuration diagram of a display device applied to the third embodiment. As shown in the figure, an example will be described in which six flexible display displays are provided and three display displays are drawn out from the half width of the display device 104.

  The display device 104 includes display control units and signal processing units of display displays 124a, 124b, 124c, 124d, 124e, and 124f, and six display displays 124a, 124b, 124c, 124d, 124e, and the like, as in the above-described embodiment. It is composed of a display drawer for drawing out 124f, a display area detector, and a signal processor (not shown). The display control unit and the signal processing unit are configured to rotate in the display device 104 and wind up the six display displays 124a, 124b, 124c, 124d, 124e, and 124f, respectively. The display display may be monochrome or color.

This figure shows a state in which the display screens of the six display displays 124a, 124b, 124c, 124d, 124e, and 124f in the display device 104 are pulled out, and shows a form in an actual use situation. In the figure, the lengths of the six display displays are different from each other, but can be extended to the same length. The signal processing unit and the signal input unit 155 may be connected by a signal cable, or may transmit display data wirelessly.
Note that the display area detection and display control of the display are the same as in the second embodiment described above, and it is possible to simultaneously browse up to six types of materials and broadcast / recorded video having different input formats.

  By providing a display in this way, it is possible not only to divide the display unit in the vertical and horizontal directions, but also to change the pull-out area asymmetrically in the horizontal direction and to cope with various installation environments. it can.

  In each of the above-described embodiments, it is assumed that the number of display displays pulled out in the vertical direction is the same. However, the number of display displays pulled out in the left half and the right half may be different, and further divided in the left-right direction. The number of display displays may be different in the left and right divided areas.

  In the said Example 2, 3, although the usage pattern like a self-light-emitting roll screen was assumed, it is not limited to this, The usage pattern in which the display apparatus main body was reduced in size for the mobile terminal as a portable device It may be. Moreover, it is good also as a system containing the content described in Example 1. FIG.

In the first to third embodiments, a case where a plurality of images, that is, so-called multi-screen display is not performed in one display display has been described. However, the present invention is not limited to this, and the processing circuit is complicated but convenient. In the case of pursuing characteristics and the like, a configuration may be adopted in which a plurality of images are combined and format-converted and displayed on a single display.
An optimal system may be configured as appropriate according to applications such as portability and convenience.

  The display device of the present invention can be applied to applications such as a display device for mobile terminals such as an electronic book or a mobile phone, a display device for car navigation, a display device for self-luminous roll screen.
