JP 2007-316098 A

ところが、従来のように合成樹脂製キャビネットにおける額縁部の後面全周に不織布帯が両面テープにより貼着されている表示装置にあっては、不織布帯と、該不織布帯に付設される両面テープとが必要であるため、部品点数が増加し、不織布帯の貼付けによる組立て工数も増加し、コスト高になる。また、リサイクルのために表示装置が解体されるとき、額縁部の全周に亘って貼着されている不織布帯の剥取り作業が必要であり、また、不織布帯を剥取ることなくキャビネットがリサイクルされる場合、キャビネットと異なる材料により形成されている不織布帯及び両面テープがキャビネットとともにリサイクル材料となり、キャビネットによるリサイクル材料の純度が低くなり、改善策が要望されていた。   However, in a display device in which a non-woven fabric band is attached to the entire rear surface of the frame portion of the synthetic resin cabinet with a double-sided tape as in the past, a non-woven fabric band and a double-sided tape attached to the non-woven fabric band; Therefore, the number of parts is increased, the number of assembling steps by attaching the nonwoven fabric band is increased, and the cost is increased. In addition, when the display device is dismantled for recycling, it is necessary to remove the non-woven fabric band that is attached to the entire periphery of the frame, and the cabinet can be recycled without removing the non-woven fabric strip. In this case, a nonwoven fabric band and a double-sided tape formed of a material different from the cabinet become a recycled material together with the cabinet, and the purity of the recycled material by the cabinet is lowered, and an improvement measure has been demanded.

本発明は斯かる事情に鑑みてなされたものであり、主たる目的は表示パネルの周縁部を後保持体とにより保持する前保持体の前記緩衝体と向き合う箇所に、前後に貫通する複数の孔又は欠除部を設け、額縁部及び前記緩衝体の少なくとも一方に、前記孔又は欠除部に挿入し、且つ他方に接触する突起を設けることにより、額縁部に不織布帯等の緩衝部材を設けることなく、表示パネルの微振動による音鳴りを防ぐことができる表示装置を提供することにある。   The present invention has been made in view of such circumstances, and a main object is to provide a plurality of holes penetrating front and rear at locations facing the buffer body of the front holding body that holds the peripheral edge of the display panel with the rear holding body. Alternatively, a cushioning member such as a non-woven fabric band is provided on the frame portion by providing a cutout portion, and providing a projection that is inserted into the hole or the cutout portion and in contact with the other at least one of the frame portion and the buffer body. Therefore, it is an object of the present invention to provide a display device that can prevent sound generation due to slight vibration of the display panel.

本発明に係る表示装置は、前側に表示面を有する表示パネルと、該表示パネルの周縁部前側に配される額縁部を有し、前記表示パネルの周縁部及び後側を隠蔽するキャビネットと、該キャビネット内で前記表示パネルの前側及び後側に配され、該表示パネルの周縁部を前後に保持する前保持体及び後保持体とを備え、前記前保持体と前記表示パネルとの間に緩衝体を設けてある表示装置において、前記前保持体は前記緩衝体と向き合う箇所に、前後に貫通する複数の孔又は欠除部を有し、前記額縁部及び緩衝体の少なくとも一方は、前記孔又は欠除部に挿入され、且つ他方に接触する突起を有することを特徴とする。   The display device according to the present invention has a display panel having a display surface on the front side, a frame portion arranged on the front side of the peripheral edge portion of the display panel, and a cabinet for concealing the peripheral edge portion and the rear side of the display panel; A front holding body and a rear holding body that are arranged on the front side and the rear side of the display panel in the cabinet and hold the peripheral edge of the display panel back and forth, and between the front holding body and the display panel. In the display device provided with the buffer body, the front holding body has a plurality of holes or notches penetrating in front and rear at a position facing the buffer body, and at least one of the frame portion and the buffer body is It has a protrusion inserted into the hole or notch and in contact with the other.

この発明にあっては、前保持体及び表示パネルの間に設けられている緩衝体に、額縁部が突起により接触しているため、表示パネルの微振動により額縁部が表示パネル及び前保持体に当接するのを、額縁部に不織布帯を設けることなく防ぐことができ、表示パネルの微振動による音鳴りを防ぐことができる。また、前保持体の後側に配される緩衝体が不織布帯を兼ねているため、部品点数及び組立て工数を削減でき、コストの低減を図ることができる。また、リサイクルのために解体されるとき、剥ぎ取り作業を行うことなくキャビネットだけに分別することができ、解体作業性を高めることができる。   In this invention, since the frame portion is in contact with the buffer provided between the front holding body and the display panel by the projection, the frame portion is caused to vibrate by the slight vibration of the display panel. Can be prevented without providing a non-woven fabric band on the frame portion, and noise caused by slight vibration of the display panel can be prevented. Moreover, since the buffer body arranged on the rear side of the front holder also serves as the nonwoven fabric band, the number of parts and the number of assembling steps can be reduced, and the cost can be reduced. Moreover, when dismantling for recycling, it can be separated into only cabinets without stripping work, and dismantling workability can be improved.

また、本発明に係る表示装置は、前記キャビネットは合成樹脂製であり、前記突起は前記キャビネットと一体に成形してある構成とするのが好ましい。   In the display device according to the present invention, it is preferable that the cabinet is made of synthetic resin, and the protrusion is formed integrally with the cabinet.

この発明にあっては、表示パネルの隠蔽状態を維持することができるように比較的硬質の材料により成形されるキャビネットと一体に突起が成形されているため、前記緩衝体の位置ずれに影響されることなく突起を孔又は欠除部に挿入することができ、組立て作業性を高めることができる。   In this invention, since the projection is formed integrally with the cabinet formed of a relatively hard material so that the concealed state of the display panel can be maintained, it is affected by the position shift of the buffer body. Thus, the protrusion can be inserted into the hole or notch portion without increasing the assembly workability.

また、本発明に係る表示装置は、前記孔は、その長手方向が前記周縁部に沿う方向へ配されている長孔である構成とするのが好ましい。
この発明にあっては、前保持体の孔による強度低下を低減でき、且つ表示パネルが比較的大形であっても、額縁部の突起を前保持体の孔に挿入し易くでき、組立て作業性をより一層高めることができる。 In the display device according to the present invention, the hole is preferably a long hole whose longitudinal direction is arranged in a direction along the peripheral edge.
According to the present invention, it is possible to reduce a decrease in strength due to the hole of the front holding body, and even when the display panel is relatively large, it is easy to insert the projection of the frame portion into the hole of the front holding body, and the assembly work The sex can be further enhanced.

本発明によれば、表示パネルの微振動により額縁部が表示パネル及び前保持体に当接して音鳴りするのを防ぐための部品点数及び組立て工数を削減でき、コストを低減できる。しかも、リサイクルのために解体されるとき、剥ぎ取り作業を行うことなくキャビネットだけに分別することができ、解体作業性を高めることができる。   According to the present invention, it is possible to reduce the number of parts and the number of assembling steps for preventing the frame portion from coming into contact with the display panel and the front holding body due to slight vibration of the display panel, and to reduce the cost. Moreover, when dismantling for recycling, it can be separated into only cabinets without stripping work, and dismantling workability can be improved.
