  The present invention relates to a flat image display device, and more particularly to a technique for improving mechanical reliability when a flat image display device is attached to a TV set.

  Conventionally, a color cathode ray tube has been widely used as a display device excellent in high luminance and high definition. However, with the recent improvement in image quality of information processing devices and television broadcasts, there is an increasing demand for flat image display devices (flat panel displays, FPDs) that have high luminance and high definition characteristics and are lightweight and space-saving. ing.

  As typical examples, liquid crystal display devices, plasma display devices and the like have been put into practical use. In particular, a self-luminous display device using electron emission from an electron source to a vacuum (for example, an electron emission image display device, a field emission image display device, etc.) that can increase the brightness is available. In addition, various flat-type image display devices such as an organic EL display characterized by low power consumption have been put into practical use.

  Among flat image display devices, a self-luminous flat panel display is known in which electron sources are arranged in a matrix.

  In a self-luminous flat panel display, the cold cathode has a Spindt type, surface conduction type, carbon nanotube type, metal-insulator-metal stacked MIM (Metal-Insulator-Metal) type, metal-insulator An electron source such as a metal-insulator-semiconductor (MIS) type in which semiconductors are stacked or a metal-insulator-semiconductor-metal type is used.

  The flat-type image display device includes a rear substrate having the electron source as described above, and a phosphor layer and an anode that forms an acceleration electrode for projecting electrons emitted from the electron source onto the phosphor layer. 2. Description of the Related Art A display panel is known that includes a front substrate and a support that serves as a sealing frame that seals the opposing internal spaces of both substrates in a predetermined vacuum state. An image display device is operated by combining a drive circuit with this display panel.

  In an image display device having an electron source, a plurality of first electrodes (for example, a cathode electrode and an image signal electrode) arranged in parallel in a second direction extending in the first direction and intersecting the first direction; An insulating film formed to cover the first electrode, and a plurality of second electrodes (for example, gate electrodes) extending in the second direction on the insulating film and arranged in parallel in the first direction , A scanning signal electrode), and a back substrate having an electron source provided near the intersection of the first electrode and the second electrode, the back substrate having a substrate made of an insulating material. The electrode is formed on the top.

  With this configuration, scanning signals are sequentially applied to the scanning signal electrodes in the first direction. On the substrate, the above-described electron source is provided at or near each intersection of the scanning signal electrode and the image signal electrode. These two electrodes and the electron source are connected by a feeding electrode, and a current is supplied to the electron source. Supplied. Opposite to the rear substrate, a front substrate having a plurality of color phosphor layers and a third electrode (anode electrode, anode) on the opposing inner surface is provided. The front substrate is formed of a light transmissive material suitable for glass. Then, a frame member serving as a sealing frame is inserted and sealed around the inner peripheral edge of the two substrates, and the inside formed by the rear substrate, the front substrate, and the support is evacuated to constitute a display panel.

  As described above, the electron source has at or near the intersection of the first electrode and the second electrode, and the amount of electrons emitted from the electron source by the potential difference between the first electrode and the second electrode (emission on). (Including OFF) is controlled. The emitted electrons are accelerated by a high voltage applied to the anode of the front substrate, and are also projected and excited by the phosphor layer of the front substrate, so that the emitted light is colored light according to the emission characteristics of the phosphor layer. Color develops.

Each electron source is paired with a corresponding phosphor layer to constitute a unit pixel. Usually red (R),
One pixel (color pixel, pixel) is constituted by unit pixels of three colors of green (G) and blue (B). In the case of a color pixel, the unit pixel is also called a sub-pixel (sub-pixel).

In the flat type image display device as described above, a plurality of spacing members (hereinafter referred to as spacers) are generally arranged and fixed in a display region surrounded by the support body between the rear substrate and the front substrate.
The distance between the two substrates is maintained at a predetermined distance in cooperation with the support. This spacer is generally formed of a plate-like body formed of an insulating material such as glass or ceramics, and is usually installed at a position where the operation of the pixel is not hindered for each of the plurality of pixels.

Further, the frame material to be a sealing frame is fixed to the inner peripheral edge of the back substrate and the front substrate with a sealing member such as frit glass, and this fixing portion is hermetically sealed to form a sealing region. The degree of vacuum inside the display area formed by both the substrates and the support is, for example, 10 ⁻³ to 10 ⁻⁵ Pa.

  A first electrode lead terminal connected to the first electrode formed on the rear substrate and a second electrode lead terminal connected to the second electrode penetrate through the sealing region between the support and both substrates. Usually, a frame material to be a sealing frame is fixed to the rear substrate and the front substrate with a sealing member such as frit glass. The first electrode lead terminal and the second electrode lead terminal are led out through a sealing region which is an airtight attachment portion between the sealing frame and the rear substrate. “Patent Document 1” is given as a description of such a display device. As a structure for attaching the display device thus manufactured to a set or the like, for example, “Patent Document 2” can be cited.

JP 2004-363075 A Japanese Patent Laid-Open No. 9-244545

  A plan view of the display panel completed as described above is shown in FIG. In FIG. 12, the front glass substrate is smaller than the back glass substrate. Terminals of image signal electrodes and scanning signal electrodes are formed at the end of the rear glass substrate. The flexible wiring board 3 is connected to this terminal. In order to incorporate the display panel into the display device, as shown in FIG. 13, the back glass substrate of the display panel is fixed to the metal plate 4 as the support on the display device side by the double-sided adhesive tape 5. In FIG. 13, a metal plate 4 as a support is provided with a step 41 for reinforcing the strength. Further, since the display panel needs to be evacuated to make the inside vacuum, an exhaust pipe 6 for this purpose is necessary. In order to avoid the exhaust pipe 6 for exhaust, the metal plate 4 as a support is provided with a notch 42. In the example of FIG. 13, there are two exhaust pipes 6, but four cutouts 42 of the metal plate 4 as a support are provided.

  FIG. 14 is a schematic side view of the display panel. In FIG. 14, the flexible wiring board 3 and the exhaust pipe 6 are omitted. The display panel is made of glass on both the front and back. Moreover, since the inside is a vacuum, it always receives atmospheric pressure from the outside. Therefore, as shown in FIG. 14, when an impact F is applied from the outside, there arises a problem that the front glass is broken.

  As a countermeasure against this, as shown in FIG. 15, a protective glass 9 or a plastic plate is pasted with a transparent resin 99 in front of the front glass. However, such a prior art requires a bonding process of the protective glass 9 in addition to the problem that the weight is increased by the amount of the protective glass 9 and the like, which causes a problem that the manufacturing cost for this is high. .

  The above-mentioned “Patent Document 2” describes a structure for attaching a display panel to a housing such as a TV set, but this is intended to prevent the display panel from being detached from the support. The subject and the effect differ from invention.

  Therefore, the present invention has been made to solve the above-described conventional problems. In other words, since the metal plate on the back and the display panel are conventionally firmly fixed, the entire external impact is received only by the display panel. Therefore, the display panel needs to maintain high mechanical strength. It was. On the other hand, in the present invention, the joint between the metal plate and the display panel has a flexible structure or an elastic structure, so that an impact from the outside is applied to the metal plate or the joint between the metal plate and the display panel. I am trying to make it manage. The specific configuration is as follows.

(1) A display device comprising a display panel having a front substrate and a rear substrate, and a support that supports the display panel by bonding to the rear substrate of the display panel,
The display device according to claim 1, wherein a joint portion between the rear substrate and the support has a spring structure with respect to a main surface direction of the display panel.
(2) The display device according to (1), wherein the front substrate and the rear substrate are made of glass.
(3) The display device according to (1), wherein the support is a plate-like support.
(4) The display device according to (1), wherein the support is a plate-like metal.
(5) A tongue piece is formed by cutting the plate metal constituting the support, and the back substrate is joined to the tongue piece of the plate metal (4) The display device described in 1.
(6) The display device according to (5), wherein a plurality of the tongue pieces are formed on the plate-like metal, and the display panel is supported by the plurality of tongue pieces.
(7) The display device according to (5), wherein a long side of the tongue piece portion is a long side direction of the display screen.
(8) A notch is formed in the plate-like metal constituting the support, and a portion formed by the notch has a plane existing above the main surface of the plate-like metal and exists above the The display device according to (4), wherein the display device is bonded to the display panel on a plane to be displayed.

(9) A display device comprising a display panel having a front substrate and a rear substrate, and a support that supports the display panel by bonding to the rear substrate of the display panel, the rear substrate and the support A display device characterized in that a plate spring is installed between the two.
(10) The display device according to (9), wherein a plurality of the plate springs are formed.

  (11) A display device comprising a display panel having a front substrate and a rear substrate, and a support that supports the display panel by bonding to the rear substrate of the display panel, the rear substrate and the support A display device characterized in that a coiled spring is installed between the two.

  According to the present invention, since the external impact is absorbed by the joint portion between the display panel and the support portion such as a metal plate, the probability of breakage of the display panel with respect to the external impact can be greatly reduced. In addition, since it is not necessary to install a protective glass or the like on the front glass substrate as a countermeasure against external impact, the weight of the entire display device can be reduced. In addition to the elimination of the protective glass and the like, a process for adhering the protective glass and the like is not necessary, so that the manufacturing cost can be greatly reduced.

  According to the means of (1) to (8) of the present invention, a spring structure is formed between the display panel and the support body as an impact mitigating means for the display panel without the need to add special parts. Therefore, a highly reliable display device can be obtained without an increase in manufacturing cost.

  Further, according to the means (9) to (10) of the present invention, since the plate spring is used as the impact reducing means, an optimum configuration as the impact reducing means can be easily set.

  Furthermore, according to the means (11) of the present invention, since the coil spring is used as the impact mitigating means, an optimum configuration can be easily set as the impact mitigating means.

  The best mode of the present invention will be described below in detail with reference to the drawings of the embodiments. The display panels in the following embodiments can be similarly applied not only to FED type display panels but also to plasma display panels, liquid crystal display panels, and the like. In the following embodiments, the metal plate 4 as a support is taken as an example of the support for the display panel. However, the support need not be limited to the metal plate 4 as long as it has a similar effect.

  FIG. 1 shows a first embodiment of the present invention. FIG. 1A shows a display panel to which the present invention is applied. FIG.1 (b) is the metal plate 4 which is a support body for attaching a display panel by this invention. The thickness of the front glass substrate of the display panel in FIG. 1A is 2.8 mm, the thickness of the rear glass substrate is 2.8 mm, and the distance between the front glass substrate and the rear glass substrate is 3 mm.

  In FIG. 1B, the surface attached to the rear glass of the display panel is described as the upper surface. In FIG.1 (b), the thickness of the metal plate 4 which is a support body is 1.2 mm to 1.5 mm, and generally a steel plate is used. Cutouts 42 for avoiding the exhaust pipe 6 are provided at four corners of the metal plate 4 as a support. Although there are four notches 42, in the present embodiment, the exhaust pipe 6 is only two places. Further, the metal plate 4 as a support is provided with a step portion 41 for increasing the strength.

  The feature of the present embodiment is that a notch 431 is added to the metal plate 4 as a support around the pasting material such as a double-sided tape that joins the back glass substrate and the metal substrate, and a tongue piece 43 is formed. Yes. This tongue piece 43 provides elasticity at the joint between the metal plate 4 as the support and the rear glass substrate. Thus, when an impact is applied to the display panel from the outside, that is, from the front, the joint is elastically moved rearward, so that the impact is absorbed.

  FIG. 2 shows an enlarged cross-sectional view of the joint between the display panel and the metal plate 4 as a support in the present invention. When an impact F is applied from the outside, the joint between the metal plate 4 as a support and the rear glass substrate of the display panel is displaced in the y direction in FIG. 2 to absorb the impact. Although FIG. 2 uses a double-sided adhesive tape 5 as an adhesive for the joint, this double-sided adhesive tape 5 has a thickness of about 1 mm, so the tongue piece 43 can be displaced up to about 1 mm depending on the strength of the impact. Is possible. That is, impact absorption is possible. There are various types of double-sided tape, which can be determined in consideration of the strength of the impact to be absorbed and the necessary adhesive strength.

  The formation of the tongue piece 43 of the metal plate 4 serving as the support can be simultaneously formed when the metal plate 4 serving as the support is punched out by pressing, so that the cost of parts and production are not increased. The width of the notch 431 forming the tongue piece 43 may be determined in consideration of the life of the press die. In general, the thickness may be equal to or greater than the thickness of the metal plate 4 as a support.

  3 (a) and 3 (b) show a second embodiment of the present invention. FIG. 3A shows a display panel, which is the same as that of the first embodiment. FIG. 3B shows a metal plate 4 as a support in this embodiment. In the present embodiment, two tongue pieces 43 on the metal plate 4 as a support are provided with two narrow pieces in the vertical direction.

  The tongue piece 43 of the metal plate 4 serving as a support in the present invention functions in the same manner as a leaf spring. Therefore, the elasticity of the tongue piece 43 part of the metal plate 4 as the support is proportional to the cube of the plate thickness of the metal plate 4 as the support and proportional to the width of the tongue piece 43 part. It is proportional to the Young's modulus of 4. If the thickness of the metal plate 4 as a support to be used is large, the rigidity is too strong, and the effect of the present invention may not be sufficiently expected. In such a case, the spring force as a leaf spring can be adjusted by reducing the width of the tongue piece 43 part.

  The cross-sectional shape of the joint between the display panel and the metal plate 4 as a support in this case is the same as that in the first embodiment. That is, it is the same as FIG.

  4 (a) and 4 (b) show a third embodiment of the present invention. FIG. 5 is a cross-sectional view taken along line AA in FIG. FIG. 4A shows a display panel, which is the same as that of the first embodiment. FIG. 4B shows a metal plate 4 as a support to be joined to the display panel. In this embodiment, the metal plate 4 as a support at the portion where the display panel and the metal plate 4 as a support are joined is formed with a cut-and-raised portion 44 instead of a tongue piece 43 formed by a simple cut 431.

  As shown in FIG. 5, the cut and raised portion 44 has a height h. By providing the cut and raised 44 in this way, the displacement in the y direction can be increased when an impact is applied, and a large impact can be absorbed.

  The purpose of the cut-and-raised portion 44 in FIG. 5 is to absorb an impact by displacement, and therefore it is not necessary to increase the height h. Even the thickness of the metal plate 4 as a support is sufficient. Note that increasing h increases the overall thickness of the display device.

  Also, the dimension of d in FIG. 5 that determines the shape of the root of the cut-and-raised portion is not a problem when h is small. When the dimension of d is large, the elasticity of the tongue piece 43 part of the metal plate 4 as a support member includes an element that is inversely proportional to the dimension of d. Depending on the dimension of d, the cross section of the cut and raised portion can take various shapes.

  6 (a) and 6 (b) show a fourth embodiment of the present invention. 6A shows the display panel, and FIG. 6B shows the metal plate 4 as a support for supporting the display panel. The display panel shown in FIG. 6A is the same as that of the first embodiment. In the metal plate 4 as a support in this embodiment shown in FIG. 6B, the direction of the tongue piece 43 is opposite to that in the first embodiment. The shape of the display panel, the thickness of the metal plate 4 as a support, the outer shape, etc. are the same as in the first embodiment.

  The cross-sectional view showing the joint portion between the display panel and the metal plate 4 as the support in the fourth embodiment is also substantially the same as the first embodiment except for the direction. In Example 1, although the example which adjusts the width | variety and number of the tongue piece parts 43 in order to adjust elasticity was described in Example 2, it cannot be overemphasized that it can apply to Example 4 similarly.

  Further, in Example 1, in order to increase the amount of displacement with respect to the impact, the joint portion of the metal plate 4 serving as the support body with the display panel is not the tongue piece portion 43 by the simple cut 431 but the cut and raised portion 44. As described in the third embodiment, it is needless to say that the same effect can be obtained in the fourth embodiment if the cut-and-raft 44 is used.

  FIGS. 7A and 7B show a fifth embodiment of the present invention. FIG. 7A shows a display panel. The display panel of the embodiment is the same as that of the first embodiment. FIG. 7B shows a metal plate 4 as a support in the fifth embodiment. In the fifth embodiment, a plurality of tongue pieces 43 formed by the cuts 431 are formed in the vertical direction. The shape of the display panel, the thickness of the metal plate 4 as a support, the outer shape, etc. are the same as in the first embodiment.

  The cross-sectional view showing the joint portion between the display panel and the metal plate 4 as the support in the fourth embodiment is also substantially the same as the first embodiment except for the direction. In Example 1, although the example which adjusts the width | variety and number of the tongue piece parts 43 in order to adjust elasticity was described in Example 2, it cannot be overemphasized that it can apply to Example 4 similarly.

  Further, in Example 1, in order to increase the amount of displacement with respect to the impact, the joint between the metal plate 4 serving as the support and the display panel is not the tongue piece 43 formed by mere cutting, but the cut and raised 44. As described in the third embodiment, it is needless to say that in the third embodiment, the same effect can be obtained by cutting and raising 44.

8 (a) and 8 (b) show a sixth embodiment of the present invention. FIG. 8A is a schematic plan view of the display panel. In FIG. 8A, the flexible wiring board 3 and the like are omitted. FIG. 8B is a side view of FIG. The feature of the sixth embodiment is that a plate-like spring 7 is separately installed as a spring material, not the notch 42 or the cut-up 44 of the metal plate 4 as a support. Stainless steel is suitable as a material for the plate spring 7.
In FIG. 8B, the display panel and the leaf spring are joined with an adhesive tape. Moreover, since the joining of the plate spring 7 and the metal plate 4 as a support is both metal, spot welding is simple and highly reliable.

  By using a plate-like spring 7 separately from the metal plate 4 as a support, the elasticity for absorbing the impact can be freely selected. In other words, the spring force is proportional to the cube of the plate thickness, proportional to the plate width, and proportional to the Young's modulus, but by using the plate spring 7 separately, these factors can be freely selected and optimal elasticity is achieved. You can set the force.

  In the sixth embodiment, three plate springs 7 are installed on the center of the screen. However, the number and arrangement of the plate springs 7 are not limited to this. For example, the number of plate-like springs 7 may be one, or four may be arranged in a balanced manner in two upper and lower rows. It is determined in consideration of the absorption of impact by the plate spring 7 and the reliability and balance of the connection between the plate spring 7 and the metal plate 4 or display panel as a support.

  9 (a) and 9 (b) show a seventh embodiment of the present invention. FIG. 9A is a schematic plan view of the display panel. In FIG. 9A, the flexible wiring board 3 and the like are omitted. FIG. 9B is a side view of FIG. The feature of the sixth embodiment is the same as that of the sixth embodiment in that the plate-like spring 7 is installed separately as an elastic structure instead of the notch 42 and the cut-up 44 of the metal plate 4 as a support.

  In the sixth embodiment, the plate spring 7 is installed in the horizontal direction of the display screen, but in the seventh embodiment, it is installed in the vertical direction of the screen. The plate-like spring 7 and the display panel are joined with an adhesive tape, and the plate-like spring 7 and the metal plate 4 as a support are joined by spot welding as in the sixth embodiment. Even with such an arrangement, the same effect as in the fifth embodiment can be obtained. The direction, number, arrangement, etc. of the springs are the size of the display panel, the strength of the shock to be absorbed, the strength of the joint between the display panel and the plate spring 7, and the plate spring 7 and the metal plate 4 as the support. Determined by considering the strength of bonding.

  FIG. 10A and FIG. 10B show examples of the plate spring 7 used in the eighth embodiment. FIG. 10A is a plan view of the plate spring 7, and FIG. 10B is a side view of the plate spring 7. In FIG. 10B, the flat part 71 is bonded to the display panel via the double-sided adhesive tape 5. The flat part 72 is spot-welded to the metal plate 4 that is a support, which is a support. The inclined portion 73 in FIG. 10B functions as a spring.

  In order to increase the reliability of joining the display panel and the plate spring 7, the flat portion 71 of the plate spring 7 should be wide. On the other hand, a specific value may be selected for the plate thickness t of the plate spring 7 due to material restrictions. In such a case, if the width w1 in FIG. 10 (a) is increased in order to increase the area of the flat portion 71, the rigidity of the plate spring 7 increases, and the effect of the present invention may be reduced. In such a case, as shown in FIG. 10A, the action of the spring can be adjusted by reducing the width w2 of the portion 73 acting as a spring. Conversely, when it is desired to increase the composition of the springs, the width of the inclined portion 73 of the plate spring 7 may be increased.

  FIG. 11 (a) and FIG. 11 (b) show a ninth embodiment of the present invention. FIG. 11A is a schematic plan view of the display panel. In FIG. 11A, the flexible wiring board 3 and the like are omitted. FIG.11 (b) is a side view of Fig.11 (a). The feature of the ninth embodiment is that, as an elastic structure, the plate-like spring 7 is separately installed instead of the notches 42 and the cut-ups 44 of the metal plate 4 as a support, as in the sixth embodiment. The spring is not a single-side support (cantilever) but a double-side support spring 8.

  By using both-side support, the display panel and the metal plate 4 as a support can be joined with good balance. Although there is a possibility that the elasticity may be reduced by using both-side support, this can be adjusted by the plate thickness, width, etc. of the spring material.

  11 (a) and 11 (b) show an example in which three plate springs 7 are arranged in the horizontal direction of the screen. However, the number, arrangement, orientation, etc. of the both-side support springs 8 are not necessarily limited to this example. .

  In the sixth and seventh embodiments, the plate spring 7 is used as a spring, but the spring material is not necessarily limited to the plate spring 7. The same effect can be obtained even when a coil spring is used at the joint between the display panel and the metal plate 4 as a support, which is a support.
