Description

  The present invention relates to an image display device, and more particularly to a flat-type image display device of a type in which electrons emitted from an electron emission type electron source collide with a phosphor to emit light.

  As described in Non-Patent Document 1, there are various types of field emission image display devices which are one type of flat image display device. The most common basic structure is that a cathode substrate on which a field emission electron source is formed and an anode substrate on which a phosphor is applied are arranged facing each other through a predetermined gap, and are hermetically sealed. A vacuum envelope that holds the space between the substrates in a vacuum is provided. In order to keep the inside of the vacuum envelope in a vacuum, the vacuum envelope needs to withstand a load of atmospheric pressure. Therefore, when a thick glass plate is used as the cathode substrate and the anode substrate, the weight of the vacuum envelope becomes excessively large. In recent years, the diagonal size of the screen size of the flat-type image display device tends to increase to about 32 inches, and the thickness of the glass substrate has to be increased in accordance with the increase in the screen size, which has been a big problem.

  Therefore, instead of using a thick glass plate for both the cathode substrate and the anode substrate, it has been proposed to use a thick glass plate for the anode substrate but a thin glass plate for the cathode substrate. Maintaining the gap between the cathode substrate and the anode substrate can increase the number of spacers sandwiched between the cathode substrate and the anode substrate and increase the resistance to atmospheric pressure load. The excessive increase has a drawback of deteriorating the display quality of the image display device. By reducing the thickness of the spacer, the display quality deterioration due to the spacer is also suppressed, but it is difficult to manufacture, arrange, and assemble the spacer so thin that it is not visible from the outside of the image display device, There is a problem that the spacer is charged up and causes an image to be disturbed, and there has been a demand for a structure of an image display device that can eliminate the spacer or reduce the number of spacers as much as possible.

  Patent Document 1 forms a flat display tube container by adhering a box-shaped outer back panel formed of a material having mechanical strength and rigidity larger than glass to a display panel made of a transparent glass plate, The structure which provides an inner back panel made of glass inside the outer back panel is disclosed. With this configuration, the inner back panel is made of glass, but its thickness and weight are reduced.

  Patent Document 2 discloses that a plurality of metal box-shaped back plates are overlapped and joined to a front plate made of a transparent glass plate to form a plurality of independent vacuum chambers, and a pressure difference between the plurality of vacuum chambers. The structure which provides is disclosed. With this configuration, the atmospheric pressure is divided and applied to each back plate, and a vacuum container for a lightweight and thin display device is formed.

  In Patent Document 3, a vacuum is formed between a face panel made of glass having a phosphor screen formed on its inner surface and a rear envelope made of glass that is sealed with frit glass facing the face panel. An envelope is formed, and the inside of the vacuum envelope is evacuated to a vacuum. At this time, the space between the face panel and the substrate on which the electron-emitting device is formed is secured by sandwiching the substrate on which the electron-emitting device is formed on the seal surface between the face panel and the rear envelope. The spacer for holding is made unnecessary.

  In Patent Document 4, a spacer is installed at the peripheral edge between the cathode panel and the anode panel facing each other, and the spacer is bonded to each of the cathode panel and the anode panel so as to create a space between the cathode panel and the anode panel. A vacuum is maintained, and a reinforcing plate is bonded to the back surface of the cathode panel using an adhesive. The reinforcing plate is made of a material having a Young's modulus larger than that of the glass constituting the cathode plate and a small specific gravity.

  On the other hand, as a method of attaching the hermetic envelope constituting the display device to the housing of the display device, Patent Document 5 discloses that the back surface of the display panel is bonded and fixed to the chassis member in the housing via a double-sided adhesive tape. Disclosure.

  When the display panel described in Patent Documents 1 to 4 is bonded and fixed to the housing via a double-sided adhesive tape, directly or via a chassis, as in the technique described in Patent Document 5, the display panel front side Since a relatively thick and heavy glass plate is used for the front substrate, the front side of the display panel is heavy and unbalanced, and there is a problem with the adhesive strength of the adhesive tape.

  An object of the present invention is to provide an image display device which can be reduced in weight and thickness without causing deterioration in display image quality and in which the reliability of a display panel holding structure is enhanced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings for explaining the embodiments, parts having the same function are given the same reference numerals, and repeated explanation thereof is omitted.

  The present invention can be applied to an image display device in which a plurality of electron sources using field emission or the like are arranged in a matrix, and the phosphors emit light by projecting electrons from the electron sources onto the phosphors. .

  That is, for example, disclosed in JP-A-11-162383, JP-A-2002-55652, etc., an image display device (hereinafter referred to as CNT-FED) whose electron source is composed of carbon nanotubes, or Similarly, it can be applied to an image display device disclosed in JP-A-11-162383, JP-A-2002-55652, etc., whose electron source is composed of a cone-shaped Spindt type field emission cathode. It is. In the present invention, an electron source using field emission or the like other than an image display device using a CNT-FED and a Spindt-type cathode is arranged in a matrix, and electrons from the electron source are projected onto a phosphor to emit fluorescence. Needless to say, the present invention is applicable to a front image display device that emits light from a body.

  FIG. 1 is an exploded schematic perspective view showing a configuration of an image display apparatus according to a first embodiment of the present invention. In FIG. 1, the part of the image display device corresponding to the lower right quadrant of the screen surface of the anode substrate 2 is taken as an example, its plan view is shown in FIG. 2, its A arrow view is shown in FIG. 4 is a sectional view taken along the line B, FIG. 5 is a sectional view taken along the arrow B, and FIG. In FIG. 4, a display panel 200 of an image display apparatus 100 includes an anode substrate 2 having a phosphor 1 forming an image display surface formed on the inner surface thereof, and a flat cathode substrate 4 provided with an electron source 3. The electron source 3 is opposed to the phosphor 1 with a predetermined gap to form an airtight vacuum envelope, and the inside of the vacuum envelope is evacuated to a vacuum. Note that the phosphor 1 and the electron source 3 are formed separately for each pixel in an actual display panel, but in the drawings attached to this specification, they are shown as an integral unit for the sake of simplicity.

  The image display apparatus 100 according to the present embodiment is configured by a metal dish-shaped reinforcing body 300 fixed to the cathode substrate 4 of the display panel 200.

  In the drawings attached to the present specification, for the sake of simplicity, illustration of electrode structures, electrical wirings, external lead electrode terminals and the like formed on the anode substrate 2 and the cathode substrate 4 is omitted and clarified. For this reason, each element in the drawing may be exaggeratedly drawn using a scale ratio different from that of an actual display device.

  The anode substrate 2 is a transparent glass having a phosphor 1 film formed on the surface thereof, and the display portion is formed in a flat plate shape having a thickness of 10 mm, for example. The anode substrate 2 is formed in a quadrangle (specifically, a rectangle, for example, 400 mm × 300 mm). The cathode substrate 4 has a number of electron sources 3 formed on the surface thereof, and is formed in a flat plate shape. The cathode substrate 4 is formed in a slightly larger quadrangle (specifically, a rectangle) than the anode substrate 2 and thinner than the anode substrate 2 (for example, 2.8 mm).

  As the material of the cathode substrate 4, it is preferable to use glass in view of the formation process of the electron source 3 and electrical wiring (not shown), the consistency of the linear expansion coefficient with the anode substrate 2, and the like. However, a silicon substrate or a metal plate such as Kovar or 42 alloy, for example, having an insulating layer on the surface may be used.

  The anode substrate 2 and the cathode substrate 4 are joined so that the phosphor 1 and the electron source 3 are parallel to each other in the facing direction. A space between the anode substrate 2 and the cathode substrate 4 is formed as an electron emission chamber 6 whose outer periphery is sealed. The electron emission chamber 6 is evacuated to a vacuum, and when the electrons emitted from the electron source 3 strike the phosphor 1, the phosphor 1 emits light and displays an image.

  For example, in FIG. 4, the electron source 3 is illustrated with the electron source arrangement region as a single unit, but in reality, a large number of electron sources are two-dimensionally arranged. In FIG. 4, the phosphor 1 is also shown as an integral region for the phosphor 1, but in the case of a color panel, for example, red, green, and blue phosphors are two-dimensional corresponding to the electron source. Are arranged.

  The reinforcing body 300 in the present embodiment is formed by processing a metal plate into a container shape. The reinforcing body 300 is hermetically sealed to the cathode substrate 4 with a sealing material (not shown) such as frit glass, for example, and the reinforcing body 300 is independent of the electron emission chamber 6 together with the cathode substrate 4. An airtight chamber is formed. Further, in the present embodiment, the inside of the airtight chamber formed by the reinforcing body 300 and the cathode substrate 4 is evacuated to a pressure lower than the atmospheric pressure.

  In the field emission type image display device 100, the inside of the electron emission chamber 6 is evacuated to a vacuum. Therefore, when atmospheric pressure is directly applied to the cathode substrate 4, the cathode substrate 4 bends toward the inside of the electron emission chamber 6, and the phosphor 1 And the electron source 3 cannot be maintained at a desired value. If the cathode substrate 4 is made thicker to reduce this deflection, for example, in a large image display device having a diagonal diameter of 32 inches or more, the weight increases and the commercial value decreases. In the present embodiment, the cathode substrate 4 and the reinforcing body 300 hermetically sealed to the cathode substrate 4 form an airtight chamber, and the airtight chamber is evacuated to a vacuum, so that atmospheric pressure is directly applied to the cathode substrate 4. Therefore, even if the cathode substrate 4 is thin, the deflection of the cathode substrate 4 due to the atmospheric pressure can be reduced.

  As the reinforcing body 300, it is desirable that the linear expansion coefficient is close to that of the cathode substrate 4, and for example, a Kovar thin plate, a metal thin plate such as Fe—Ni alloy, stainless steel, 42 alloy, iron, copper, and aluminum can be used. .

The degree of vacuum inside the electron emission chamber 6 is preferably a high vacuum of about 10 ⁻⁶ Torr so that electrons are stably emitted from the electron source 3. On the other hand, the degree of vacuum inside the reinforcing body 300 does not need to be a high vacuum from the viewpoint of shortening the manufacturing process. Since a pressure corresponding to the pressure difference between the inside of the electron emission chamber 6 and the inside of the reinforcing body 300 is applied to the cathode substrate 4, if this pressure difference becomes smaller than the pressure difference that can be withstood by the rigidity of the cathode substrate 4 itself. Good.

  In the above embodiment, the metal reinforcing body 300 is used, but instead of this metal reinforcing body 300, it is also possible to use a glass-made reinforcing body in the same manner as in the above embodiment. . The other points are basically the same as those in the first embodiment. An airtight chamber is formed by the cathode substrate 4 and the reinforcing body by hermetically sealing the dish-shaped reinforcing body to the cathode substrate 4 using an adhesive such as frit glass. The inside of the hermetic chamber is evacuated to a vacuum similar to the case of the first embodiment, and the pressure is lower than the atmospheric pressure. Also in this case, the cathode substrate 4 and the glass reinforcing member hermetically sealed to the cathode substrate 4 form an airtight chamber, and the airtight chamber is evacuated to a vacuum, so that atmospheric pressure is directly applied to the cathode substrate 4. Therefore, even if the cathode substrate 4 is thin, the deflection of the cathode substrate 4 due to the atmospheric pressure can be reduced. Accordingly, it is possible to increase the resolution, reduce the weight, and reduce the thickness of the large-sized image display device.

  In the above embodiment, the reinforcing body 300 or a glass reinforcing body having the same shape is hermetically sealed to the cathode substrate 4 to form an airtight chamber between the cathode substrate 4 and the airtight chamber. Although the configuration is such that the vacuum chamber is evacuated and the inside of the hermetic chamber is set to a pressure lower than the atmospheric pressure, a configuration in which the reinforcing body does not form the hermetic chamber with the cathode substrate 4 may be employed. For example, a substantially plate-shaped metal plate may be fixed to the outside of the cathode substrate 4 of the display panel 200 via an adhesive. In this case, in order to further increase the effect, a substantially plate-like metal reinforcing body provided with a large number of ribs is provided on the outside of the cathode substrate 4 of the display panel 200, and an adhesive is attached to the cathode substrate 4 at the rib portion. May be fixed. In this case, an airtight chamber is not formed between the reinforcing body and the cathode substrate 4. For example, since a large number of linear ribs are formed over a wide area in the reinforcing body, even if the thickness of the cathode substrate 4 fixed thereto is thin, the amount by which the cathode substrate 4 bends due to atmospheric pressure. Can be kept within an allowable range. The ribs are not limited to a linear shape, and may be provided in a lattice shape.

  Here, returning to FIG. 1 and FIG. Panel holding members 400 are attached to the left and right side surfaces of the display panel 200 by, for example, an adhesive (not shown). The panel holding member 400 is provided with an attachment screw hole 410 for inserting an attachment screw 420 (see FIG. 8) for attaching the display panel 200 to a housing of a TV set, for example. 7 is a front view of the TV set 500 on which the display panel 200 is mounted, FIG. 8 is an exploded perspective view of the TV set 500, FIG. 9 is a side view of the TV set 500, and FIG. 10 is the TV set of FIG. 500 is a sectional view taken along line XX of FIG. 11, FIG. 11 is a sectional view taken along line XI-XI of the TV set 500 of FIG. 7, and FIG. 12 is a detailed view of part A of FIG. In FIG. 8, reference numeral 510 indicates the front case of the TV set, reference numeral 520 indicates the rear case of the TV set, and reference numeral 530 indicates the stand of the TV set.

  As described above in detail, in this embodiment, the display panel 200 is held from the side surface, so that the holding strength of the display panel 200 is improved, and the number of parts for holding the display panel 200 and the manufacture of the display panel 200 holding member are increased. Man-hours are reduced, cost reduction is achieved, and the design of the final product can be improved by integrating the set frame of the display device and the panel holding member.

  In the above embodiment, the panel holding member 400 is fixed to the anode substrate 2, but the panel holding member 400 is fixed to the reinforcing body 300 side by an adhesive or welding as shown in FIG. However, it is needless to say that the same effect as the above embodiment can be obtained. Furthermore, it goes without saying that the panel holding member 400 may be provided on both the anode substrate 2 and the reinforcing body 300. Furthermore, in the above-described embodiment, the screw 420 that engages with the panel holding member 400 is inserted through the side wall of the front case 510 of the TV set, but the panel holding member is inserted so that the screw 420 passes through the rear case 520 of the TV set. 400 shapes may be configured. Furthermore, the shape of the panel holding member 400 may be configured such that the screw 420 that engages with the panel holding member 400 passes through the front surface of the front case 510 of the TV set.

In the above embodiment, the panel holding member 400 is fixed to the left and right side surfaces of the display panel. Of course. Furthermore, it is a matter of course that the same effect as the embodiment can be obtained even when the panel holding member 400 is fixed to the upper, lower, left and right side surfaces of the display panel. According to the present invention, the display image quality is not deteriorated. Thus, an image display device that can be reduced in weight and thickness and that has a highly reliable display panel holding structure can be obtained.
