Description

  The present invention relates to a display device including a light-transmitting protective plate that covers a display surface of a display device body, and a method for manufacturing the same.

  Conventionally, as a display device having such a configuration, a configuration in which a protective plate is attached to a frame body to which a display device main body is attached using various attachment mechanisms is known (see, for example, Patent Literature 1 to Patent Literature 8).

  The device described in Patent Document 1 is provided with a screw hole corresponding to the insertion hole of the flange portion on the front panel having a substantially rectangular cross section whose rear surface is in contact with the flange portion of the rear cover that covers the rear portion of the display device using the plasma display panel. ing. Insert the holder into the groove around the inner periphery of the opening on the front panel. The optical filter is assembled by attaching a screw to the screw hole through the insertion hole so that the peripheral edge of the optical filter for preventing unnecessary radiation and correcting the color is held between the holder and the flange portion of the rear cover.

  However, in the configuration described in Patent Document 1, since the optical filter is assembled with a screw in the holder, two types of members, the holder and the screw, are necessary for assembling the optical filter. Stopping work is necessary, and improvement in manufacturability cannot be obtained. Further, even when the optical filter is replaced when it is damaged by an external impact, for example, the screw must be removed and attached, which complicates the operation.

  In the device described in Patent Document 2, a peripheral portion of a plate body to which a boss provided on the back surface of the plasma display panel unit is fixed with screws is bent at a substantially right angle with respect to the plate surface to form a bent portion. The tip of the bent portion is further bent to provide a screwing portion that is parallel to the substantially plate surface of the plate body. Fasten with screws to the boss that stands on the inside of the front frame. The optical filter is assembled by screwing the screw into the bent part inside the front frame in the screw hole opened in the peripheral part of the optical filter made of translucent acrylic or the like.

  However, in the configuration described in Patent Document 2, it is necessary to make a screw hole in the optical filter. For example, when the optical filter is formed of a glass substrate or the like, the manufacture of the optical filter becomes complicated, and further, the screws are fixed. In order to achieve this, it is necessary to form the optical filter larger, and the improvement in manufacturability cannot be obtained. Further, since the optical filter is assembled by screwing, the work becomes complicated. Furthermore, when replacing the optical filter, remove the front frame that is fixed to the plate with screws, remove the optical filter that is screwed to the front frame, attach the new optical filter to the front frame, and then attach the optical filter. Further, since the front frame is fixed to the plate body with screws, there are many operations for removing and fixing screws, and the operation is complicated.

  In the device described in Patent Document 3, a filter panel for the purpose of color correction, light shielding, and the like is positioned at a positioning portion that serves as a positioning reference for mounting the front case, and is mounted with a filter mounting bracket. The filter mounting bracket to which the filter panel is attached is fixed to the front case with a fastening part with the filter panel interposed therebetween. The front case is attached to the rear case to which the plasma display panel is attached by being screwed by an attachment boss disposed on the rear case.

  However, in the configuration described in Patent Document 3, since the filter panel is attached to the front case attached to the rear case to which the plasma display panel is attached by the filter mounting bracket, the number of members for assembling the filter panel is large. The number of attachment processes is large, and improvement in manufacturability cannot be obtained.

  The thing of patent document 4 arrange | positions the edge part of an optical filter in the 1st flat part of the rectangular frame which consists of an up-and-down left-right side part in which the inner surface was formed in step shape. Screw the partial metal fittings formed in a step shape corresponding to the inner surface of the frame body into a state in which the edge of the optical filter is pressed and fixed to the first flat portion through a gasket having conductivity and elasticity. Stop and fix. The back cover that covers the back of the frame is fixed with screws to the frame, and the plasma display panel is assembled so as to be covered with the optical filter, the partial bracket, and the back cover.

  However, in the configuration described in Patent Document 4, since the optical filter is screwed and fixed to the frame with a partial metal fitting, two types of members, the partial metal fitting and a screw, are necessary to attach the optical filter, and the number of parts is small. In addition to the increase, screwing work is necessary, and the improvement of manufacturability cannot be obtained. In addition, when replacing the optical filter, remove the screw fixing of the back cover after removing the screw fixing of the back cover, fix the new optical filter to the frame with the partial metal fitting, and then fix the back cover with the screw. Therefore, there are many releasing and fixing operations with screw fixing, and the operation is complicated.

  In the device described in Patent Document 5, guide rails are attached to the upper and lower portions around the display surface of a housing that accommodates the plasma display panel with screws. A stopper is formed at one end of the guide rail with a spring material having elasticity in the longitudinal direction of the guide rail. The optical filter is inserted from the side into the gap between the guide rail and the housing, and is screwed to the housing on the opposite side of the stopper.

  However, in the configuration described in Patent Document 5, it is necessary to provide a configuration such as a hole for screwing the optical filter to the housing. For example, when the optical filter is formed of a glass substrate or the like, the optical filter In addition, the manufacturing of the optical filter becomes complicated, and further, it is necessary to form a large optical filter for screwing, so that the improvement of the productivity cannot be obtained. Further, since the optical filter is assembled by screwing, the work becomes complicated.

  The thing of patent document 6 screws a front glass filter to the inner chassis attached to a rear case with a screw with a filter attachment metal fitting. Secure the front cover to the inner chassis and the rear case with hooks to cover the inner chassis.

  However, in the configuration described in Patent Document 6, since the front glass filter is attached to the inner chassis with a screw with a filter mounting bracket, two types of members, a filter mounting bracket and a screw, are necessary to assemble the front glass filter. As the number of parts increases, screwing work is required, and the productivity cannot be improved.

  In the one described in Patent Document 7, one end of four sheet metal members is brought into contact with each back surface of the outer peripheral four sides of the optical filter, and the fitting grooves formed in the four outer frame bodies on each of the four sides are optically connected. It fits so that a filter and a thin sheet metal member may be clamped. Four outer frame bodies are fixed to the front surface of the outer peripheral four sides of the back case having an electromagnetic shielding effect to which the plasma display panel is attached by a connecting member such as a screw.

  However, in the configuration described in Patent Document 7, the optical filter is attached to the four outer frames with thin sheet metal members, and each outer frame is fixed to the rear case with screws or the like, so the optical filter is attached. For this reason, at least two types of members, ie, a thin sheet metal member and a screw, are required, the number of parts is increased, and a screwing operation is required, so that the productivity cannot be improved.

  In the device described in Patent Document 8, at least one side portion of the front frame that houses the plasma display panel is attached to the front frame base so that it can be opened and closed outwardly with a hinge. The upper and lower front frames in the direction perpendicular to the sides are provided with grooves that open to the inside of the front frame. Insert the peripheral edge of the optical filter into the groove of the upper and lower front frame with the side released, and provide the side with a locking portion with a claw that locks to the front frame base. The optical filter is attached to the front frame base through the through hole.

  However, in the configuration described in Patent Document 8, it is necessary to provide a through hole for attaching the optical filter to the front frame. For example, when the optical filter is formed using a glass substrate or the like, the manufacture of the optical filter is complicated. Furthermore, it is necessary to form the optical filter larger by at least the size of the through hole, and the improvement in manufacturability cannot be obtained. Furthermore, the side part for attaching the optical filter must be disposed on the front frame base part so as to be openable and closable, the structure becomes complicated, and the productivity cannot be improved.

The second piece portions 252 and 253 hold the front surface portion 211. Further, by pressing, the urging portion 251C of the first piece 251 abuts on the periphery of the optical filter 400, the first piece 251 is further elastically deformed so that a gap is opened, and the urging portion 251C Get over it. Then, the clip member 250 is attached to the frame body 210 in a state in which the step portion 251A of the first piece portion 251 is in contact with the peripheral surface of the optical filter 400 and cannot be inserted further. In this attached state, the front surface portion 211 of the frame main body 210 that overlaps between the urging portion 251C of the holding portion 251B of the first piece portion 251 and the second piece portions 252, 253 due to the restoring force due to elastic deformation. The optical filter 400 is held in the thickness direction that is the opposing direction of the optical filter 400 and the PDP 300, and the optical filter 400 is attached to the frame body 210 so as to face and cover the display surface 301 of the PDP 300.

  Thereafter, the engaging claw portion 244 of the decorative frame 240 is inserted into the engaging hole 215 of the frame body 210 and is engaged with the engaging piece 214, and the frame body 210 is placed on the inner peripheral side of the decorative frame 240 on the front side. The decorative frame 240 is attached to the frame body 210 so as to cover the outer periphery and the front surface of the frame body 210.

  On the other hand, for example, when the optical filter 400 is replaced, the decorative frame 240 is removed, and the clip member 250 is pulled out from the opening 217 and removed. Then, the optical filter 400 is removed from the positioning body 218 of the frame body 210 to be removed from the frame body 210. Then, the new optical filter 400 may be attached by the clip member 250 in the same manner as the assembly operation described above.

The optical filter 400 having elasticity is held by the clip member 250 with a restoring force by elastic deformation in a direction substantially along the facing direction of the display surface 301 of the optical filter 400, and the optical filter 400 is attached to the frame body 210. ing. For this reason, as in the configuration exemplified above, the clip member 250 is simply attached to the opening 217 provided in the frame body 210, and the clip member 250 is simply attached so as to be sandwiched. it can. Therefore, for example, the number of parts is small compared to the case where the optical filter 400 is attached with metal fittings, screws, screws, etc., the attachment work is easy, and there is no need to provide a hole for attaching to the optical filter 400. The optical filter 400 can be easily attached and detached with a simple configuration.

  Then, as the frame body 210, a rectangular frame plate opening the display window 211A facing the display surface 301 of the PDP 300, and the front part 211 where the peripheral part of the optical filter 400 overlaps, and the peripheral part of the front part 211 are bent in series. It is formed in a frame shape having a frame portion 212 that covers the periphery of the PDP 300 and is attached to the frame body 210 while holding the clip member 250 in a state of sandwiching the front surface portion 211 and the optical filter 400. For this reason, the clip member 250 may be configured to hold the thickness dimension of the optical filter 400 and the front surface portion 211 that simply overlap each other as compared with, for example, a shape that holds the entire frame body 210 and the optical filter 400. The shape of the clip member 250 can be simplified, the size can be easily reduced, and the productivity of the clip member 250 can be easily improved.

  Furthermore, the opening part 217 is provided in the position of the broken line 216 which is a bending part of the front-surface part 211 of the frame main body 210, and the frame part 212, and it is the 1st which mutually opposes by members, such as an elastic steel plate, as the clip member 250. By providing the piece 251 and the second piece 252 and 253 and inserting the second piece 252 and 253 into the opening 217, the front part 211 and the second piece 252 and 253 are inserted between the first piece 251 and the second piece 252 and 253. The optical filter 400 is sandwiched and attached in a state of being sandwiched. Therefore, the first piece 251 and the second piece 252 and 253 are formed in a substantially U-shaped cross section in which the first piece 251 and the second piece 252 and 253 are formed by folding the steel plate as in the configuration exemplified above, for example. It is possible to make the structure easy to manufacture with a simple structure that is pressed into a letter shape. Therefore, when attached, the clip member 250 does not protrude greatly from the frame body 210, so that the size can be easily reduced and the productivity can be easily improved.

  In particular, since the opening 217 is formed in a slit shape into which the second piece portions 252 and 253 can be inserted, a reduction in strength of the frame body 210 can be suppressed, and the region opened when the clip member 250 is attached. As a result, the leakage of electromagnetic waves generated during the operation of the PDP 300 through the opening 217 can be suppressed. Furthermore, since it is a simple configuration in which a steel plate, which is a metal plate, is bent, a configuration that can be held by a restoring force due to elastic deformation can be easily formed, and a filter process that conducts to the front side of the optical filter 400 is performed. Even in such a case, conduction through the clip member can be obtained, and prevention of electromagnetic waves by filtering can be easily obtained.

  And it inclines to the front-end | tip of the 2nd piece parts 252 and 253 inserted in the opening part 217 of the frame main body 210 diagonally on the opposite side with respect to the opposing direction of the 1st piece part 251 and the 2nd piece parts 252 and 253. In this state, the guide pieces 252A and 253A are bent. Therefore, when the second piece 252 or 253 is inserted into the opening 217 so that the front face 211 is sandwiched between the first piece 251 and the second piece 252 or 253, the position of the opening 217 is determined by the operator. Since the second pieces 252 and 253 are guided into the opening 217 while the guide pieces 252A and 253A act on the opening edge of the opening 217, the work of attaching the clip member 250 is further performed. Easy to do.

  Further, as the clip member 250, the second piece portions 252 and 253 inserted into the opening portion 217 are formed in a state in which the width dimensions of the second piece portion 252 and the second piece portion 253 are different, and the opening portion 217 also has these widths. An opening is formed to a length corresponding to the dimension. Therefore, even when a plurality of clip members 250 are attached to one side of the frame main body 210 as in the configuration exemplified above, the second piece portions 252 and 253 are erroneously inserted into the different opening portions 217 and attached. This can be easily prevented with a simple configuration, and the work efficiency of the mounting work can be further improved.

  Further, as the clip member 250, the second piece portions 252 and 253 inserted into the opening 217 are separated from the interval between the second piece portion 252 and the second piece portion 253 and the interval between the adjacent second piece portions 253. Are formed in different dimensions, and the openings 217 are also formed at intervals corresponding to these intervals. Therefore, even when a plurality of clip members 250 are attached to one side of the frame body 210 as in the configuration exemplified above, the second piece portions 252 and 253 are mistakenly inserted into the different opening portions 217 and attached. Can be easily prevented with a simple configuration, and the work efficiency of the mounting work can be further improved.

  And since it is set as the structure which attaches the several clip member 250 to one side of the frame main body 210, it becomes a transversal direction by four in the horizontal direction used as the longitudinal direction of the frame main body 210, for example like the structure illustrated above. A plurality of clip members 250 can be appropriately attached in the same shape, for example, two in the vertical direction, and the productivity can be improved by using the clip members 250 having the same shape.

  In particular, the optical filter 400 is applied to a configuration in which filter processing for suppressing transmission of electromagnetic waves generated by the operation of the PDP 300 is performed. For this reason, not only the protection of the PDP 300 but also leakage of electromagnetic waves can be prevented.

  The frame body 210 is provided with a positioning portion 218 that holds one edge of the optical filter 400. For this reason, the optical filter 400 can be easily attached in a state where the plane is in the vertical direction, the assembly versatility can be improved, and since the optical filter 400 is positioned, the attachment by the clip member 250 can be facilitated. Can be improved. In particular, since the present invention is applied to a configuration using the PDP 300, the optical filter 400 is generally attached while holding the optical filter 400 by positioning and holding the optical filter 400, which uses a glass substrate and is relatively heavy, to the positioning unit 218. There is no need to carry out the work, and only the operation of attaching the clip member 250 may be performed, the attachment can be performed particularly easily, and the workability can be particularly improved.

  And as the frame main body 210, the surface treatment is performed by conductive galvanizing or the like to impart conductivity. Accordingly, for example, when the PDP 300 having the same characteristics as the filter processing of the optical filter 400 is used on the display surface 301 without using the protective plate, the display that is filtered without using the clip member 250 is used. Conductivity can be obtained by disposing the peripheral portion of the surface 301 in contact with the front surface portion 211 of the frame body 210 or via a conductive gasket. The frame body 210 can be used for a configuration in which the optical filter 400 is not used, and the productivity can be further improved.

[Modification of Embodiment]
Note that the present invention is not limited to the above-described embodiment, and includes the following modifications as long as the object of the present invention can be achieved.

  That is, in the above-described embodiment, the configuration using the clip member 250 of the clip mechanism that holds the overlapping front surface portion 211 and the optical filter 400 is described, but the configuration is not limited thereto. For example, it can be formed in any shape that is sandwiched and held and attached, such as a shape extending from the back side to the front side of the frame body 210 so as to hold the entire frame body 210 and the optical filter 400. For example, when the entire frame body 210 and the optical filter 400 are held, the opening 217 into which the clip member 250 is inserted may not be provided, and the manufacturability of the frame body 210 can be improved.

  In addition, the clip member 250 is configured to be bent so as to fold back a steel plate and have overall elasticity, but is not limited to this configuration. For example, the first piece 251 and the second piece 252 are connected by a spring member so that a restoring force by elastic deformation acts in the opposing direction of the first piece 251 and the second pieces 252 and 253. , 253 itself is not elastically deformed, and any configuration can be applied in which the gap between each other acts and holds in the direction in which the restoring force is reduced. As described above, any configuration in which the metal plate or the like is not bent, for example, the first piece portion 251 and the second piece portions 252 and 253 are connected by a leaf spring member can be applied.

  And although the 2nd piece parts 252 and 253 were formed in the different width dimension, you may form in the same width dimension. In such a case, it is preferable to provide the gaps different from each other, since attachment at an incorrect position can be prevented. Further, the second piece portions 252 and 253 have been described with different intervals, but may be formed at the same interval. Even in such a case, in order to prevent attachment in an incorrect position, it is preferable to form in different width dimensions.

  Further, although the guide pieces 252A and 253A are provided and described, they may not be provided. Further, the step portion 251A is provided, but the step portion 251A is not provided, but the first piece portion 251 is formed obliquely from the folded portion with the second piece portions 252 and 253, and is held at the tip portion of the first piece portion 251. A portion 251B and an urging portion 251C may be provided. Alternatively, only the urging portion 251C may be provided without providing the holding portion 251B, or only the holding portion 251B may be provided without providing the urging portion 251C. That is, the clip member 250 to which the optical filter 400 is attached can have any shape that is sandwiched and held.

  Further, the frame body 210 is not limited to the frame shape having the front surface portion 211 and the frame portion 212 described above, and may have any shape that covers the periphery of the display device body such as the PDP 300. Further, the positioning part 218 may not be provided. In such a case, the optical filter 400 may be attached in a state where the plane of the display window 211A is substantially horizontal.

  Moreover, although the optical filter 400 was demonstrated in the state which overlaps with the front surface part 211 directly, it is good also as a state which overlaps via the soft member which has electroconductivity, such as a gasket. When this gasket is used, it may be provided at any position on the front surface 211 side or the optical filter 400 side. The optical filter 400 is a filter that can be formed of various materials such as a glass substrate and an acrylic plate that have a light-transmitting property so that the state displayed on the display surface 301 can be visually recognized. It is good also as a structure which protects simply without performing a process.

  The present invention is not limited to the above-described embodiment and modifications of the embodiment, and various applications are possible without departing from the object of the present invention.

The optical filter 400 having elasticity is held by the clip member 250 with a restoring force by elastic deformation in a direction substantially along the facing direction of the display surface 301 of the optical filter 400, and the optical filter 400 is attached to the frame body 210. ing. For this reason, for example, the clip member 250 can be attached by a simple operation in which the clip member 250 having elasticity is simply attached to the opening 217 provided in the frame body 210 and is simply inserted so as to be sandwiched. Therefore, for example, the number of parts is small compared to the case where the optical filter 400 is attached with metal fittings, screws, screws, etc., the attachment work is easy, and there is no need to provide a hole for attaching to the optical filter 400.
