Description

本発明は、表示装置、及び複数の表示装置を互いに連結して画像を表示する多画面表示装置に関する。 The present invention relates to a display device, and relates to a multi-screen display equipment which displays an image by a plurality of display devices connected to each other.

近年、表示装置において、軽量化、薄型化及び画面サイズの大型化等が要求されている。その要求を満たす1つの手段として、複数の表示装置を組み合わせ電気的に接続して、多画面表示または大画面表示を行う多画面表示装置がある。この種の多画面表示装置は、連結される個々の表示装置の数を増減させることにより、全体としての画面サイズを容易に調節することができる。そのため、企業のショールーム等に常設される場合だけでなく、イベント会場などにおいて一時的に設置される場合にも利用される。すなわち、イベント会場等において商品紹介やその他の情報提供を行うために、イベント期間中に設置され、そしてイベント終了とともに撤去される。
これら個々の表示装置の背面には、取り付け用の金具等が設置されており、組み立て用の架台にそれぞれの表示装置を近接させて取り付け固定し、多画面表示装置として設営される。
In recent years, display devices are required to be lighter, thinner, and larger in screen size. One means for satisfying the requirement is a multi-screen display device that performs multi-screen display or large-screen display by combining and electrically connecting a plurality of display devices. This type of multi-screen display device can easily adjust the overall screen size by increasing or decreasing the number of individual display devices connected. Therefore, it is used not only when it is permanently installed in a company showroom but also when it is temporarily installed at an event venue or the like. In other words, in order to introduce products and provide other information at an event venue or the like, it is installed during the event period and removed at the end of the event.
On the back surface of each of these display devices, mounting brackets and the like are installed, and each display device is attached and fixed close to an assembly base to be set up as a multi-screen display device.

このような多画面表示装置においては、装置全体で一つの画像を表示することが多く、画像の表示品質を確保するため、設営時には個々の表示装置を互いに精度よく位置決めする必要がある。例えば、特許文献1に開示されるマルチビジョン装置では、個々の単位スクリーン(表示装置)同士の位置決め用としてスクリーンフレームに目印を設け、この印に合うように各単位スクリーンを配置して、調整ネジで支持することとしている。
特開平7−209756号公報
In such a multi-screen display device, a single image is often displayed on the entire device, and in order to ensure the display quality of the image, it is necessary to position the individual display devices with accuracy with respect to each other at the time of installation. For example, in the multivision device disclosed in Patent Document 1, a mark is provided on the screen frame for positioning the individual unit screens (display devices), and each unit screen is arranged so as to match the mark, and an adjustment screw is provided. I am going to support it.
JP-A-7-209756

しかしながら、一般に上述したような多画面表示装置では、個々の表示装置同士の互いの位置決めが、隣り合う表示装置の外周部分(枠部)の端面同士を上下・左右・前後方向に夫々合わせるように行われるので、調整作業が難しく、作業者に熟練を要した。また、各表示装置の架台への固定は、位置決めに用いられる枠部から装置の奥行き方向に離間した位置でネジ止め等により行われるので、取り付けの作業性が悪く、固定に長時間を要した。
また、多画面表示装置の設置後には、表示装置の自重等に起因してネジ固定が緩むなどして、経年変化で表示装置同士の相対位置がずれてしまうことがあった。
However, in general, in the multi-screen display device as described above, the positioning of the individual display devices is such that the end faces of the outer peripheral portions (frame portions) of the adjacent display devices are aligned vertically, horizontally, and longitudinally, respectively. As it was done, adjustment work was difficult and required skill for an operator. In addition, each display device is fixed to the gantry by screwing or the like at a position separated from the frame used for positioning in the depth direction of the device, so that the mounting workability is poor and a long time is required for fixing. .
In addition, after the multi-screen display device is installed, the relative position of the display devices may be shifted due to secular change due to loosening of screws due to the weight of the display device or the like.

また、特許文献1のマルチビジョン装置においては、単位スクリーン同士の位置決め用としてスクリーンフレームに目印を設けてはいるものの、未だ調整作業が十分に簡便であるとは言えなかった。   Further, in the multivision apparatus of Patent Document 1, although the screen frame is provided with a mark for positioning the unit screens, it cannot be said that the adjustment work is sufficiently simple yet.

本発明は、上述した事情に鑑みてなされたものであって、隣り合う表示装置同士の相対的な位置決めが簡便に短時間で精度よく行え、設置作業に熟練を必要とせず、経年変化による位置ずれを防止することができる表示装置、及び多画面表示装置を提供することを目的とする。 The present invention has been made in view of the above-described circumstances, and can easily perform relative positioning between adjacent display devices in a short time with high accuracy, does not require skill in installation work, and is a position due to secular change. display device capable of preventing the displacement, and an object thereof is to provide a multi-screen display equipment.

Further, when removing the positioning member 20 from the mounting portion 17, the positioning member 20 may be rotated in a direction opposite to the above rotation.

次いで、複数のディスプレイ10を用いて配列しマルチディスプレイ1を設営する手順について説明する。
図11は、マルチディスプレイ1の一例として、4つのディスプレイ10(10A〜10D)を用い、これらディスプレイ10を上下・左右方向に各2列に配列し設営する手順を示している。
Next, a procedure for arranging and arranging the multi-display 1 using a plurality of displays 10 will be described.
FIG. 11 shows a procedure for using four displays 10 (10A to 10D) as an example of the multi-display 1 and arranging these displays 10 in two rows in the vertical and horizontal directions.

まず、図11(a)に示すように、各ディスプレイ10の枠部12の夫々の外周面12aに位置決め部材20を装着して、凹部21と凸部22とを形成する。詳しくは、図11(a)において、左上に配置されるディスプレイ10Aの右方及び下方の夫々の外周面12aの両端近傍に凹部21を夫々設ける。また、左下に配置されるディスプレイ10Bの上方の外周面12aの両端近傍に凸部22を夫々設け、右方の外周面12aの両端近傍に凹部21を夫々設ける。また、右上に配置されるディスプレイ10Cの左方の外周面12aの両端近傍に凸部22を夫々設け、下方の外周面12aの両端近傍に凹部21を夫々設ける。また、右下に配置されるディスプレイ10Dの上方及び左方の夫々の外周面12aの両端近傍に凸部22を夫々設ける。   First, as shown in FIG. 11A, the positioning member 20 is mounted on each outer peripheral surface 12 a of the frame portion 12 of each display 10 to form the concave portion 21 and the convex portion 22. Specifically, in FIG. 11 (a), concave portions 21 are provided in the vicinity of both ends of the outer peripheral surface 12a on the right and lower sides of the display 10A disposed on the upper left. Further, convex portions 22 are provided in the vicinity of both ends of the upper outer peripheral surface 12a of the display 10B disposed at the lower left, and concave portions 21 are provided in the vicinity of both ends of the right outer peripheral surface 12a. Moreover, the convex part 22 is each provided in the both ends vicinity of the left outer peripheral surface 12a of the display 10C arrange | positioned on the upper right, and the recessed part 21 is each provided in the both end vicinity of the lower outer peripheral surface 12a. Further, convex portions 22 are provided in the vicinity of both ends of the outer peripheral surface 12a on the upper and left sides of the display 10D arranged on the lower right.

次いで、図11(b)に示すように、互いに上下方向に配置されたディスプレイ10A及び10B、ディスプレイ10C及び10Dを夫々接続する。詳しくは、ディスプレイ10Aの下方の外周面12aの2つの凹部21と、ディスプレイ10Bの上方の外周面12aの2つの凸部22とを嵌め合わせて、ディスプレイ10A及び10Bを接続する。   Next, as shown in FIG. 11B, the displays 10A and 10B and the displays 10C and 10D arranged in the vertical direction are connected to each other. Specifically, the two concave portions 21 of the outer peripheral surface 12a below the display 10A and the two convex portions 22 of the upper outer peripheral surface 12a of the display 10B are fitted together to connect the displays 10A and 10B.

また、ディスプレイ10Cの下方の外周面12aの2つの凹部21と、ディスプレイ10Dの上方の外周面12aの2つの凸部22とを嵌め合わせて、ディスプレイ10C及び10Dを接続する。この状態で、ディスプレイ10A及び10Bをこれらディスプレイ10A,10Bの背面に設置された組み立て用架台2に固定し、ディスプレイ10C及び10Dをこれらディスプレイ10C,10Dの背面に設置された組み立て用架台2に固定する。   Further, the two concave portions 21 on the outer peripheral surface 12a below the display 10C and the two convex portions 22 on the outer peripheral surface 12a above the display 10D are fitted together to connect the displays 10C and 10D. In this state, the displays 10A and 10B are fixed to the assembly base 2 installed on the back of the displays 10A and 10B, and the displays 10C and 10D are fixed to the assembly base 2 installed on the back of the displays 10C and 10D. To do.

次いで、図11(c)に示すように、互いに左右方向に配置されたディスプレイ10A及び10C、ディスプレイ10B及び10Dを夫々接続する。詳しくは、ディスプレイ10Aの右方の外周面12aの2つの凹部21と、ディスプレイ10Cの左方の外周面12aの2つの凸部22とを嵌め合わせて、ディスプレイ10A及び10Cを接続するとともに、ディスプレイ10Bの右方の外周面12aの2つの凹部21と、ディスプレイ10Dの左方の外周面12aの2つの凸部22とを嵌め合わせて、ディスプレイ10B及び10Dを接続する。この状態で、ディスプレイ10A,10Bを固定する組み立て用架台2と、ディスプレイ10C,10Dを固定する組み立て用架台2とを連結する。   Next, as shown in FIG. 11C, the displays 10A and 10C and the displays 10B and 10D arranged in the left-right direction are connected to each other. Specifically, the two concave portions 21 of the right outer peripheral surface 12a of the display 10A and the two convex portions 22 of the left outer peripheral surface 12a of the display 10C are fitted to connect the displays 10A and 10C. The two concave portions 21 of the right outer peripheral surface 12a of 10B and the two convex portions 22 of the left outer peripheral surface 12a of the display 10D are fitted together to connect the displays 10B and 10D. In this state, the assembly base 2 for fixing the displays 10A and 10B and the assembly base 2 for fixing the displays 10C and 10D are connected.

このように4つのディスプレイ10を接続することで、夫々の枠部12の前面が面一とされ、多画面を有するマルチディスプレイ1が形成される。マルチディスプレイ1を構成する各ディスプレイ10は、互いに電気的に接続されるとともにPC等の制御手段(不図示)に連結され、同期して全体で一つ又は複数の画像を表示する。また、マルチディスプレイ1の外周面に形成される夫々の取付部17は、シール等の貼着部材やキャップを用いて封止しておくことが好ましい。   By connecting the four displays 10 in this way, the front surfaces of the respective frame portions 12 are flush with each other, and the multi-display 1 having a multi-screen is formed. Each display 10 constituting the multi-display 1 is electrically connected to each other and coupled to a control means (not shown) such as a PC, and displays one or a plurality of images in synchronization. Moreover, it is preferable to seal each attachment part 17 formed in the outer peripheral surface of the multi-display 1 using sticking members, such as a seal | sticker, and a cap.

以上説明したように、本実施形態のマルチディスプレイ1によれば、複数のディスプレイ10の夫々の枠部12の外周面12aには、この外周面12aより表示部11側に向け窪む凹部21と、この外周面12aより表示部11側の反対側に向け突出する凸部22とが設けられているので、マルチディスプレイ1を設営する際、隣接する各ディスプレイ10の夫々の凹部21と凸部22とを互いに嵌合させることで、ディスプレイ10同士の上下・左右・前後方向の相対的な位置決めが簡便に精度よく行える。   As described above, according to the multi-display 1 of the present embodiment, the outer peripheral surface 12a of each frame portion 12 of the plurality of displays 10 has the concave portion 21 that is recessed from the outer peripheral surface 12a toward the display unit 11 side. Since the convex portion 22 that protrudes from the outer peripheral surface 12a toward the opposite side of the display portion 11 is provided, when the multi-display 1 is set up, the concave portion 21 and the convex portion 22 of each adjacent display 10 are provided. , And the relative positioning of the displays 10 in the vertical, horizontal, and longitudinal directions can be performed easily and accurately.

従って、設置作業に熟練を必要とせず、作業が短時間で行える。また、各ディスプレイ10の凹部21と凸部22とが互いに嵌合した状態で設置されるので、経年変化等によってディスプレイ10同士の位置ずれが生じる虞がない。   Therefore, no skill is required for the installation work, and the work can be performed in a short time. In addition, since the concave portions 21 and the convex portions 22 of the respective displays 10 are installed in a state of being fitted to each other, there is no possibility that positional deviation between the displays 10 occurs due to secular change or the like.

また、枠部12には、外周面12aより窪む取付部17が形成され、この取付部17に着脱可能な位置決め部材20が設けられている。そして、位置決め部材20には、取付部17に対し着脱する方向(軸線方向)の一端部に凹部21が形成されるとともに、他端部に凸部22が形成されている。すなわち、この位置決め部材20の一端部を外方に向け取付部17に装着するか、又は、他端部を外方に向け取付部17に装着するかを選択することで、枠部12の外周面12aに凹部21を形成するか凸部22を形成するかを種々に設定できる。   Further, the frame portion 12 is formed with a mounting portion 17 that is recessed from the outer peripheral surface 12 a, and a detachable positioning member 20 is provided on the mounting portion 17. The positioning member 20 is formed with a concave portion 21 at one end in a direction (axial direction) to be attached to and detached from the mounting portion 17 and a convex portion 22 at the other end. That is, the outer periphery of the frame portion 12 can be selected by selecting whether one end portion of the positioning member 20 is attached to the attachment portion 17 facing outward or the other end portion is attached to the attachment portion 17 facing outward. It is possible to set variously whether the concave portion 21 or the convex portion 22 is formed on the surface 12a.

従って、各ディスプレイ10の外周面12aに、種々の目的・用途に合わせ凹部21又は凸部22を自由に選択し形成することができる。よって種々様々な設置の要望に対応可能である。また、位置決め部材20として凹部用と凸部用の2種類の部材を用意するような必要がなく、部材共通化が可能である。   Therefore, the concave portion 21 or the convex portion 22 can be freely selected and formed on the outer peripheral surface 12a of each display 10 according to various purposes and applications. Therefore, it can respond to various requests for installation. Further, it is not necessary to prepare two types of members for the concave portion and the convex portion as the positioning member 20, and the member can be shared.

また、ディスプレイ10の搬送時には、枠部12の外周面12aに凸部22を形成する位置決め部材20を予め該ディスプレイ10から取り外しておくことができるので、該凸部22が他の部材等に接触することで破損するようなことが防止される。
ここで、ディスプレイ10の搬送時に、位置決め部材20を全て外周面12aに凹部21を形成するように装着しておくこととすれば、位置決め部材20の紛失を防止することもできるためより好ましい。
Further, when the display 10 is transported, the positioning member 20 that forms the convex portion 22 on the outer peripheral surface 12a of the frame portion 12 can be removed from the display 10 in advance, so that the convex portion 22 contacts other members or the like. This prevents damage.
Here, when the display 10 is transported, it is more preferable that all the positioning members 20 are mounted so as to form the recesses 21 on the outer peripheral surface 12a because the positioning member 20 can be prevented from being lost.

また、位置決め部材20が螺合により取付部17に着脱されるので、枠部12の外周面12aに凹部21又は凸部22を簡便に形成でき、着脱作業が容易に行える。
また、凹部21又は凸部22が、枠部12の外周面12aの両端近傍に夫々配置されるので、より精度よくディスプレイ10同士を位置決めでき、また外力等に起因したディスプレイ10同士の相対的な位置ずれが生じにくい。
Further, since the positioning member 20 is attached to and detached from the attachment portion 17 by screwing, the concave portion 21 or the convex portion 22 can be easily formed on the outer peripheral surface 12a of the frame portion 12, and the attachment / detachment work can be easily performed.
Moreover, since the recessed part 21 or the convex part 22 is arrange | positioned in the both-ends vicinity of the outer peripheral surface 12a of the frame part 12, respectively, the displays 10 can be positioned more accurately, and relative of the displays 10 resulting from external force etc. is relative. Misalignment is unlikely to occur.

尚、本発明は前述の実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
例えば、本実施形態では、各ディスプレイ10の外周面12aに取付部17が夫々形成され、この取付部17に位置決め部材20を装着することで凹部21又は凸部22を形成することとして説明したが、本発明とは技術思想が異なる参考例としては、外周面12aに一体に凹部21と凸部22とを形成することとしてもよい。
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the present embodiment, the mounting portion 17 is formed on the outer peripheral surface 12 a of each display 10, and the concave portion 21 or the convex portion 22 is formed by attaching the positioning member 20 to the mounting portion 17. As a reference example having a technical idea different from that of the present invention , the concave portion 21 and the convex portion 22 may be integrally formed on the outer peripheral surface 12a.

また、本実施形態では、位置決め部材20に凹部21及び凸部22が背向するように一体に形成されることとして説明したが、参考例としては、例えば位置決め部材20を2種類用意し、夫々の位置決め部材20に凹部21又は凸部22のいずれか一方が形成されることとしても構わない。 In the present embodiment, it has been described that the positioning member 20 is integrally formed so that the concave portion 21 and the convex portion 22 face away from each other. However, as a reference example , for example, two types of positioning members 20 are prepared. Any one of the concave portion 21 or the convex portion 22 may be formed on the positioning member 20.

また、本実施形態では、凹部21を略円柱穴状に形成し、略円柱状の凸部22を嵌合することとして説明したが、凹部21と凸部22は互いの外周面12a同士を当接して嵌合できればよく、それ以外の形状であっても構わない。すなわち、例えば凹部21を略角柱穴状に形成するとともに、凸部22を略角柱状に形成し、これら凹部21と凸部22を嵌合することとしても構わない。   In the present embodiment, the concave portion 21 is formed in a substantially cylindrical hole shape and the substantially cylindrical convex portion 22 is fitted. However, the concave portion 21 and the convex portion 22 contact each other on the outer peripheral surfaces 12a. Any other shape may be used as long as it can be fitted in contact. That is, for example, the concave portion 21 may be formed in a substantially prismatic hole shape, the convex portion 22 may be formed in a substantially rectangular column shape, and the concave portion 21 and the convex portion 22 may be fitted.

また、本実施形態では、位置決め部材20が、枠部12の取付部17に螺合により装着されることとして説明したが、これに限らず、例えばそれ以外の接着や嵌め合い等による装着であっても構わない。   In the present embodiment, the positioning member 20 has been described as being attached to the attachment portion 17 of the frame portion 12 by screwing. However, the present invention is not limited to this, and for example, it may be attachment by other adhesion or fitting. It doesn't matter.
