Description

  The present invention relates to a display device, and particularly preferably relates to a liquid crystal display device including a liquid crystal display panel as a display panel.

  FIG. 8 is an exploded perspective view schematically showing a conventional example of a configuration of a main part of a liquid crystal display device including a transmissive liquid crystal display panel. The liquid crystal display device 9 shown in FIG. 8 includes a liquid crystal display panel 91, a frame 92 and a bezel 93 having functions of holding and protecting the liquid crystal display panel 91, and other predetermined members.

  Projected guides 921 are provided at predetermined positions on each side of the frame 92, and the liquid crystal display panel 91 is disposed in a region surrounded by the guides 921. Sponge-like cushioning materials 922 are provided at locations where the four sides of the liquid crystal display panel 91 on the inner peripheral surface side of these guides 921 are disposed. Further, a sponge-like cushioning material (not visible in FIG. 8) is also provided on the back side of the bezel 93 (that is, the side facing the liquid crystal display panel 91; the lower side in FIG. 8).

  A liquid crystal display panel 91 is disposed on the front side of the frame 92 (referred to as the upper side in FIG. 8), and a bezel 93 is mounted from the front side. Therefore, the liquid crystal display panel 91 is sandwiched between the frame 92 and the bezel 93 via the buffer material 922. According to such a configuration, the cushioning material 922 protects the liquid crystal display panel 91 from impacts and vibrations, and noise generated due to vibrations and the like is generated between the liquid crystal display panel 91 and the frame 92 and / or the bezel 93. Can be prevented.

  However, such a configuration may cause the following problems. With the recent increase in the size of liquid crystal display panels, the weight of liquid crystal display panels has also increased. If the liquid crystal display panel's own weight increases, the inertial force of the liquid crystal display panel also increases. Therefore, when the liquid crystal display device vibrates or receives external shock, only the frictional force between the surface of the cushioning material and the display panel Therefore, it becomes difficult to prevent displacement and vibration of the liquid crystal display panel. For this reason, the liquid crystal display panel easily vibrates and moves against the frictional force between the liquid crystal display panel and the surface of the buffer material.

  When the liquid crystal display panel 91 moves, the edge portion may run on a guide 921 provided on the frame 92. As a result, an unexpected force is applied to the liquid crystal display panel 91 and the liquid crystal display panel 91 may be damaged. Further, when the liquid crystal display panel 91 vibrates, a TAB (Tape Carrier Package) 911 mounted on the liquid crystal display panel 91 may be intermittently or continuously twisted. As a result, the wiring provided in the TAB 911 may be damaged, or an element such as a driver IC mounted on the TAB 911 may be peeled off from the film.

For this reason, it is possible to prevent the liquid crystal display panel from being damaged by riding on the guide provided on the frame, the damage of the TAB mounted on the liquid crystal display panel, and the element mounted on the TAB being peeled off.

  Embodiments of the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is an external perspective view schematically showing the configuration of the display panel 13 held by the first display panel holding member and the second display panel holding member applied to the embodiment of the present invention.

A plurality of TABs 134 on which a source driver 135 for generating a data signal to be transmitted to the switching element is mounted at a predetermined interval on at least one of the long sides of the display panel 13.

  Further, the TAB 134 on which the source driver 135 is mounted is mounted with a printed wiring board 136 that distributes predetermined signals and the like to these. The printed wiring board 136 has an elongated and substantially rectangular shape, and is arranged so that its longitudinal direction is substantially parallel to the long side of the display panel 13.

  FIG. 2 is an external perspective view schematically showing the configuration of the first display panel holding member 11 that can be applied to the display device according to the embodiment of the present invention, and an enlarged part (A part and B part). FIG. 2 is a partially enlarged view (part A enlarged view and part B enlarged view). For convenience of explanation, the upper side in FIG. 2 is referred to as the “front side” of the first display panel holding member 11, and the lower side is referred to as the “back side”.

  The first display panel holding member 11 is a member generally called a frame. The first display panel holding member (that is, the frame) 11 is, for example, formed integrally with a resin material, formed by combining parts formed of a resin material, or made of a metal plate material and subjected to press working. They are formed integrally with each other, or formed by combining parts made of a metal material and formed by press working or the like.

  The first display panel holding member 11 has an open substantially quadrilateral shape, for example, a frame shape. Guides 111 and 112 for positioning the display panel 13 are provided on the outer peripheral side of the front surface of each side. These guides 111 and 112 are wall-like or island-like structures protruding toward the front side. The display panel 13 can be positioned by arranging the display panel 13 so as to be fitted in an area surrounded by the guides 111 and 112.

  In other words, the inner peripheral side of the front surface of each side of the first display panel holding member 11 is recessed on the back surface side, and the display panel 13 can be fitted into the recess.

  The guides 111 and 112 are provided at positions where they do not interfere with the TABs 132 and 134 attached to the display panel 13 in a state where the display panel 13 is disposed. Specifically, in the state where the display panel 13 is disposed on the front side of the first display panel holding member 11, the first display panel holding member 11 corresponding to the side where the TABs 132 and 134 of the display panel 13 are not mounted. The side is provided with a wall-shaped guide 111 over its entire length. On the other hand, the side of the first display panel holding member 11 corresponding to the side on which the TABs 132 and 134 of the display panel 13 are mounted has a floating island shape at a position that does not coincide with the TABs 132 and 134 (that is, a position that does not interfere). A guide 112 is provided.

  Moreover, the side wall 113 standing toward the back side is provided on the outer peripheral side of each side. Therefore, each side of the first display panel holding member 11 has a substantially “L” -shaped cross-sectional shape.

  In the region surrounded by the guides 111 and 112 (that is, along the inner peripheral edge of the front surface of each side), a band-shaped cushioning material 114 is provided (particularly the A-part enlarged view and the B-part enlarged view). (See diagram). Further, a buffer material 115 is also provided at a predetermined position on the inner peripheral side of the guides 111 and 112 (refer to the enlarged view of the A portion and the enlarged view of the B portion for the buffer material 115 in particular). FIG. 2 shows a configuration in which a cushioning material is provided on the inner peripheral side of the guide 112 formed in an island shape and the entire length of the guide 111 formed in a wall shape.

  These buffer materials 114 and 115 prevent the generation of abnormal noise due to vibration between the display panel 13 and the first display panel holding member 11, and protect the display panel 13 from externally applied impacts. It has a function to do. For example, a foam material can be applied to the buffer materials 114 and 115. Examples of the foam material include high-density microcell urethane foam.

  Note that the positions where the cushioning materials 114 and 115 shown in FIG. 2 are provided are examples, and the present invention is not limited to these positions. For example, as shown in FIG. 2, in addition to the configuration in which the cushioning material 114 is provided over the entire length of each side of the region surrounded by the guides 111 and 112, an island-shaped cushioning material may be provided at a predetermined interval. . Similarly, the buffer material may be scattered at predetermined positions on the inner peripheral surface of the wall-shaped guide 111.

  A layer 116 having a higher friction coefficient than that of the cushioning materials 114 and 115 is formed at a predetermined position on the surface of the cushioning materials 114 and 115 that is in contact with the display panel 13 (particularly, a portion A is enlarged). (Refer to figure and enlarged view of part B). As a method of forming the layer 116 having a high friction coefficient, for example, a method of attaching a sheet or a film made of a material having a higher friction coefficient than the cushioning materials 114, 115 to the surfaces of the cushioning materials 114, 115, a cushioning material 114, A method of coating the surface of 115 with a material having a higher friction coefficient than those of the cushioning materials 114 and 115 can be applied. Examples of the material having a high friction coefficient include natural rubber and synthetic rubber.

  In addition, as described above, if the cushioning materials 114 and 115 are made of a foam material, the surface layer of the cushioning materials 114 and 115 is heated and dissolved to remove bubbles present on the surface layer of the cushioning materials 114 and 115. It may be. When the bubbles present on the surface layers of the cushioning materials 114 and 115 disappear, the contact area between the cushioning materials 114 and 115 and the display panel 13 increases, so that the frictional force increases as a whole (that is, the friction coefficient increases). It can be seen).

  Note that the layer 116 having a higher friction coefficient than the cushioning materials 114 and 115 may be formed over the entire surface of the cushioning materials 114 and 115 in contact with the display panel 13 or may be formed in part.

  FIG. 3 is an external perspective view schematically showing the configuration of the second display panel holding member 12 applicable to the display device according to the embodiment of the present invention, and a part extracted (C portion). It is an enlarged view (C section enlarged view). For convenience of explanation, the upper side in FIG. 3 is referred to as the “rear side” of the second display panel holding member 12, and the lower side is referred to as the “front side”.

  The second display panel holding member 12 is a member generally called “bezel” or “front bezel”. The second display panel holding member (that is, “bezel” or “front bezel”) 12 is formed of, for example, a resin material, a combination of members formed of a resin material, or a metal material. It is formed integrally by using press working or a combination of parts made of metal material and formed by pressing.

  The second display panel holding member 12 has an open substantially quadrangular shape, for example, a frame shape. On the outer peripheral side of each side of the second display panel holding member 12, a side wall 121 that rises toward the back side is provided. Therefore, each side of the second display panel holding member 12 has a substantially “L” -shaped cross-sectional shape. A band-shaped cushioning material 122 is provided along the edge of the opening near the inner periphery of the back surface of each side. A layer 123 having a higher coefficient of friction than the cushioning material 122 is formed on the surface of the cushioning material that contacts the display panel 13 (see particularly the enlarged view of the portion C).

  The buffer material 122 prevents intrusion of dust and the like from between the display panel 13 and the second display panel holding member 12, and causes vibration between the display panel 13 and the second display panel holding member 12. The display panel 13 has a function of preventing the occurrence of abnormal noise caused by it and protecting the display panel 13 from external impacts. The same material as the buffer materials 114 and 115 applied to the first display panel holding member 11 can be applied to the buffer material 122.

  FIG. 4 is a cross-sectional view schematically showing a structure in which the display panel 13 is held by the first display panel holding member 11 and the second display panel holding member 12. The upper part in FIG. 4 corresponds to the upper part in FIG. 2 and the lower part in FIG. As shown in FIG. 4, the display panel 13 is disposed in a region surrounded by the guides 111 and 112 on the front side of the first display panel holding member 11, and the second display panel holding member 12 is further provided on the front side. Arranged. Therefore, the display panel 13 is held in a state of being sandwiched between the first display panel holding member 11 and the second display panel holding member 12.

  The printed wiring board 136 connected to the TAB 134 on which the source driver 135 is mounted is fixed on the outer peripheral surface of the side wall 113 of the first display panel holding member 11 using screws (not shown). .

  As shown in FIG. 4, a buffer material 114 is provided in a region surrounded by the guides 111 and 112 on the front surface of the first display panel holding member 11, and the friction coefficient is higher on the surface than these buffer materials 114. A high layer 116 is formed. The peripheral edge of the back surface of the display panel 13 is in contact with the layer 116 having a high friction coefficient. Moreover, the buffer material 115 is provided also in the internal peripheral surface of the guides 111 and 112, and the layer 116 with a high friction coefficient is provided also in those surfaces. The end face of the display panel 13 comes into contact with the layer 116 having a high friction coefficient.

  A buffer material 122 is provided near the inner periphery of the back surface of the second display panel holding member 12, and a layer 123 having a higher coefficient of friction than these buffer materials 122 is formed on these surfaces. The peripheral edge of the front surface of the display panel 13 is in contact with the layers 116 and 123 having a high friction coefficient.

  As described above, the display panel 13 includes the first display panel holding member 11 and the second display panel holding member through the cushioning materials 114 and 122 and the layers 116 and 123 formed on the surfaces thereof with a high coefficient of friction. 12 is held between the two. Layers 116 and 123 having a high friction coefficient are formed on the surfaces of the cushioning materials 114 and 122, and the display panel 13 contacts the layers 116 and 123 having a high friction coefficient. This prevents or suppresses slippage between them, and prevents or suppresses the display panel 13 from moving in the surface direction.

  For this reason, when an impact is applied from the outside or when the display panel 13 or the like vibrates, it is possible to prevent the display panel 13 from moving and its outer peripheral edge from riding on the guides 111 and 112. Therefore, it is possible to prevent or suppress the peripheral edge portion of the display panel 13 from being damaged. In addition, since the movement of the display panel 13 in the surface direction is prevented or suppressed, it is possible to prevent or suppress the unexpected application of twisting or pulling to the TABs 132 and 134 attached to the display panel 13. Therefore, breakage of the TABs 132 and 134 and separation of the gate driver 133 and the source driver 135 mounted on the TABs 132 and 134 can be prevented or suppressed.

  In addition, as long as the said effect can be show | played, the position in which the layers 116 and 123 with a high friction coefficient are formed is not limited. That is, for example, the cushioning material 114, 115, 122 may be formed over the entire area of the surface in contact with the display panel 13, or may be formed only at a specific location.

  For example, damage to the TABs 132 and 134 and peeling of the gate driver 133 and the source driver 135 are particularly parallel to the side (the long side in the configuration shown in the figure) where the TAB 134 to which the display panel 13 is connected to the printed wiring board 136 is mounted. It is likely to occur when moving to.

  That is, since one end of the TAB 134 is fixed to the display panel 13 and the other end is fixed to the printed wiring board 136, the TAB 134 is likely to be twisted when the display panel 13 moves in the above direction. For this reason, the TAB 134 is easily damaged as compared with the case where the tension is simply applied. Further, since the source driver 135 attached to the TAB 134 is generally harder than the TAB 134, when the TAB 134 is twisted, the source driver 135 is easily separated from the TAB 134.

  Therefore, in order to prevent or suppress the damage of the TAB 134 and the peeling of the source driver 135, the display panel 13 is particularly prevented from moving in a direction parallel to the side where the TAB 134 connected to the printed wiring board 136 is mounted. Or it is preferable to suppress. For this reason, of the cushioning material provided on each side of the first display panel holding member 11 and / or the second display panel holding member 12, the side on which the TAB 134 connected to the printed wiring board 136 is mounted and the side It is preferable to form the layers 116 and 123 having a high friction coefficient on the surface over the entire length of the opposing sides, and it is not necessary to form the layers in other portions.

  With such a configuration, the layers 116 and 123 having a high friction coefficient abut against the display panel 13 over the entire length in the direction in which the movement of the display panel 13 is desired to be prevented or suppressed, so that the movement in that direction is prevented or suppressed. be able to.

  As described above, the positions and ranges where the layers 116 and 123 having a higher friction coefficient than those of the cushioning materials 114, 115, and 122 are formed on the surfaces of the cushioning materials 114, 115, and 122 are not limited, and are necessary. It can be set accordingly.
