Description

  The present invention relates to an image display device including a flat display panel for displaying images such as various images and output from a PC.

In recent years, a plasma display panel (PDP), a liquid crystal television (LCD), and the like have become widespread as flat display panels. Here, these flat display panels use alternating-current commercial power (commercial power) as a driving power source for projecting images, and are converted to direct current to drive them. For this reason, the flat display panel is supplied with power from AC power (for example, see Non-Patent Document 1).

  Flat display panels are lighter than CRT-type TVs, so they have more opportunities to carry and use. In particular, since a plasma display panel can emit light and display an image on a large screen, there is a demand for use in various places including outdoors.

  However, when using commercial power (commercial power) as a power source, the degree of freedom of the place where it can be used is limited due to restrictions such as the presence or absence of a so-called outlet for receiving the supply of commercial power. There was a problem.

  Flat display panels undergo various reliability tests during the development process. For example, there are a transportation test for confirming reliability during transportation and a highland test for confirming reliability at a high altitude. Even in these reliability tests, when commercial power is used as a power source, there are restrictions on the place where the test is performed for the same reason as described above, and it is difficult to smoothly perform the reliability test. There was a case.

  In an environment where the supply of commercial power is interrupted due to a power failure or the like, not only can the image display on a flat-screen television be disabled, but also the secondary battery cannot be charged. It is difficult to display an image using the secondary battery as a power supply source.

  The present invention has been made in view of the above problems, and an image display device using a flat display panel capable of minimizing restrictions caused by using commercial power as a power supply source for driving. It aims at realizing.

  In order to solve the above problems, an image display device of the present invention includes a flat display panel, and an installation means having a fuel cell as a power supply source when the flat display panel is installed and driving the flat display panel. It is to be prepared.

  According to the present invention, since the installation means on which the flat display panel is installed includes a fuel cell as a power supply source when driving the flat display panel, this is a so-called for receiving supply of commercial power. An image display device using a flat panel display capable of minimizing restrictions such as whether or not an outlet is installed can be realized.

  That is, the invention according to claim 1 of the present invention includes a flat display panel and installation means having a fuel cell as a power supply source when the flat display panel is installed and driving the flat display panel. An image display device.

  According to a second aspect of the present invention, in the first aspect of the present invention, an electrical connection between a circuit for driving the flat display panel and the fuel cell is provided by installing the flat display panel in the installation means. It is carried out through installation means.

  According to a third aspect of the present invention, in the first aspect of the present invention, the driving of the flat display panel is switched between the driving by the commercial power and the driving by the fuel cell according to the supply state of the commercial power. To do.

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the flat display panel is a plasma display panel.

  Hereinafter, an image display device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a schematic configuration of an image display apparatus according to an embodiment of the present invention. The image display device 1 includes a flat panel display 2 that displays an image, and a table that is an installation unit 3 for installing the flat panel display 2. The installation means 3 includes a fuel cell 4 as a power supply source for driving the flat display panel 2 therein, and the flat display panel 2 is configured to be installed via a support column 5. .

  FIG. 2 is a view of the image display device according to the embodiment of the present invention as seen from the back side.

  A power terminal 4 a (not shown) of the fuel cell 4 is connected to electrodes 5 a and 5 b provided inside the support column 5 of the installation means 3 by wiring 6. The flat panel display 2 is provided with a column holder 7 that fits with the column 5. A power source (not shown) for operating each circuit for driving the flat panel display 2 is provided in the column holder 7. Electrodes 7a and 7b that are connected and in contact with the electrodes 5a and 5b are provided. Then, when the flat panel display 2 is installed on the installation means 3 by fitting the support holder 7 of the flat panel display 2 to the support column 5 of the installation means 3, the electrodes 5 a and 7 a on the left and right respectively Further, the electrode 5b and the electrode 7b are in contact with each other, whereby the power source for operating each circuit for driving the flat panel display 2 and the fuel cell 4 are electrically connected.

  Here, FIG. 3 shows a schematic circuit configuration in a block diagram. The switching means 8 switches between commercial power and a fuel cell as a power supply source for driving the flat panel display 2 according to the supply state of the commercial power. That is, when the supply of commercial power is insufficient for driving the flat panel display 2, a fuel cell is used as the power supply source, and the supply of commercial power is sufficient for driving the flat panel display 2. In this case, commercial power is used as a power supply source. Reference numeral 9 denotes a power source for operating each circuit for driving the flat panel display 2. With the above configuration, the flat display panel 2 can be driven by switching between commercial power and a fuel cell as a power supply source for driving the flat display panel 2.

  Here, the fitting of the column 5 and the column holder 7 will be described with reference to FIG. FIG. 4A shows a state before the column holder 7 is fitted to the column 5. The support 5 is made of a material different from the outer surface and the inner side, the outer surface is a conductive material, and the inner side is an insulating material. The electrodes 5 a and 5 b are fixed by insulating portions of the support column 5. Further, the inner surface of the column holder 7 is made of a conductive material and is electrically insulated from the electrodes 7a and 7b.

  And as shown in FIG.4 (b), when the support | pillar 5 and the support | pillar holder 7 are fitted together, the electrode 5a and the electrode 7a and the electrode 5b and the electrode 7b are electrically connected, respectively. Moreover, the support | pillar 5 and the support | pillar holder 7 are also electrically connected by the contact of a fitting part, and the shielding effect does not deteriorate.

  According to the above configuration, since the electrical connection is made only by installing the flat panel display 2 on the stand that is the installation means 3, it is not necessary to separately perform wiring and is simple.

  In addition, since the power supply source is switched so that the commercial power supply can be used with priority, it does not waste battery power and can be used for relocation or emergency use. it can. When using a fuel cell in an environment where there is no power supply, replenishing the fuel enables continuous use for a long time. Use a secondary battery that requires charging for continuous use. It is very advantageous compared to the case.

  As described above, according to the present invention, the installation means on which the flat display panel is installed includes a fuel cell as a power supply source when driving the flat display panel. It is possible to provide an image display device using a flat panel display capable of minimizing restrictions on receiving such as the presence or absence of a so-called outlet.
