Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel having a panel body in which a large number of plasma discharge cells are arranged, and a display.

[0002]

2. Description of the Related Art A display using a plasma display panel performs an optical display by applying a voltage to electrodes of each discharge cell of a panel body of the plasma display panel to cause a desired discharge cell to emit light. .
The discharge cells generate heat when emitting light.

[0003] The base material of the panel body is made of glass or the like. Since the heat generated in each discharge cell is hardly transmitted in the lateral direction due to the nature of the material of the base material, the temperature of the discharge cell that emits light increases significantly, but the temperature of the discharge cell that does not emit light does not increase much. Therefore, thermal degradation of some of the discharge cells proceeds quickly.
Further, since the temperature difference between the light emitting discharge cell portion and the non-light emitting discharge cell portion becomes very large, stress is generated in the panel body, and the panel body is easily broken. When the voltage applied to the electrodes of the discharge cells is increased, the brightness increases, but at the same time, the calorific value of the discharge cells increases, and the thermal deterioration of the discharge cells and the cracking of the panel body become more severe.

Therefore, conventionally, a heat radiating member having fins for radiating heat is provided so as to cover the entire back surface of the panel main body, so that heat from the discharge cells of the panel main body that emits light can be quickly radiated. The heat dissipating member is made of a material having better thermal conductivity than the substrate of the panel main body, and has a large number of fins on the back of the heat receiving portion applied to the panel main body for increasing the contact area with air. . The heat transmitted from the panel body to the heat receiving portion is quickly transmitted to the fins on the back of the panel, and is released into the air from the surface of the fins.

[0005]

However, even if a heat radiating member is provided on the back surface of the panel main body as in the conventional case, the overall or local temperature rise of the panel main body cannot be suppressed. It is sometimes the case that the heat deteriorates prematurely or the panel body cracks. this is,
This is due to the thermal connection structure between the heat receiving portion of the heat radiating member and the panel body.

[0006] The panel body is generally formed into a curved shape for manufacturing reasons, and it is difficult to make the shape of the facing portion of the heat receiving portion of the heat radiating member the same on the back surface, and there is a gap between the two. This can hinder the heat transfer from the panel body to the heat radiating member.

To cope with this, an elastic sheet having better heat conductivity than air is provided on the back surface of the panel main body, and a heat radiating member is applied thereon, and the elasticity of the elastic sheet causes the panel main body and the heat radiating member to receive heat. It is conceivable that no gap is formed between the parts.

However, to satisfy this requirement, the thickness of the elastic sheet needs to be about 2 mm or more.

This thickness does not become zero even between the portions where the panel body and the corners around the heat receiving portion are pressed, and the distance between the heat receiving portion and the back surface of the panel body cannot be reduced. I have. For this reason, the heat storage property of the elastic sheet is increased and the heat transfer resistance from the panel body to the heat receiving part is increased by the amount corresponding to the increase in the thickness of the elastic sheet in the space part. Heat is not easily transmitted to the heat radiating member, and is hardly dissipated. Therefore, the temperature rise of the panel main body cannot be sufficiently suppressed locally or as a whole.

[0010] In order to promote heat radiation, it is common to blow air to the fins with a fan. However, when a fan is used, the bearing life of the fan is shorter than that of the panel body, so it is necessary to replace the bearing during use and cause noise. It is rare.

An object of the present invention is to provide a plasma display panel and a display which have high local and overall heat radiation properties of the panel body, have no problem due to temperature rise, and can reduce or eliminate the number of fans to be installed. It is in.

[0012]

In order to achieve the above object, a plasma display panel according to the first aspect of the present invention comprises a panel body including a large number of discharge cells arranged in a vertical and horizontal plane, and a plasma display panel comprising: A heat receiving portion is applied to the back surface of the panel main body, and a heat radiating member for radiating heat received from the panel main body from the heat radiating portion on the back portion is provided. The heat receiving portion of the heat radiating member fixes the heat radiating member and the panel main body. An elastic member is provided on a portion facing the support portion, and the elastic member is pressed against the back surface of the panel body.

In such a configuration, when the heat radiating members are applied to the respective heat receiving portions on the back surface of the panel main body to achieve thermal bonding, the heat radiating members of the respective heat receiving portions and the support portion for fixing the panel main body to each other. The elastic member provided on the opposite surface of the panel prevents elastic deformation from forming a gap between the heat receiving portion and the back surface of the panel body, and the presence of air increases heat transfer resistance from the panel body to the heat receiving portion. In addition, the heat transfer from the panel body to the heat radiating member due to the presence of the elastic member can be prevented, and the heat of each part of the panel body can be efficiently transferred to the corresponding part of the heat receiving portion of the heat radiating member. While being well transmitted, the heat is quickly dissipated from the heat radiating portion in many areas on the back of the heat receiving portion while rapidly spreading to other portions of the heat receiving portion, and the local or overall temperature rise of the panel body is performed. To Suppressing the minute discharge cell can solve the problems as or cause or thermally deteriorated at an early stage, cracks in the panel body. At the same time, the number of fans is reduced to reduce the noise problem, or the fan need not be used, thereby eliminating the noise problem and the maintenance problem due to the fan bearing life. be able to.

According to a second aspect of the present invention, there is provided a plasma display panel including a panel main body including a large number of discharge cells arranged in a vertical and horizontal plane, and a heat receiving portion applied to a back surface of the panel main body to receive heat received from the panel main body. And a heat dissipating member for dissipating heat from the heat dissipating portion on the back, wherein the heat dissipating portion of the heat dissipating member is characterized in that an elastic member is baked on a portion facing the rear surface of the main body.

In such a configuration, since the elastic member is baked on the heat receiving portion of the heat radiating member, heat transfer at the boundary between the elastic member and the heat receiving portion is efficiently performed.
Even if the elastic member is not made thinner until the gap between the heat receiving part and the back surface of the panel main body is minimized, the heat of each part of the panel main body is quickly and efficiently transmitted to the corresponding part of the heat receiving part of the heat radiating member. As in the above case, the local or overall temperature rise of the panel body can be sufficiently suppressed.

If a plasma display panel having these features, an electric circuit for driving the plasma display panel, and a cabinet accommodating the plasma display panel and the electric circuit are provided, a display exhibiting the same operation and effect can be provided. can get.

In this case as well, when the heat radiating portion of the heat radiating member projects outside the cabinet, the heat radiating portion directly contacts the room temperature air outside the cabinet to improve the heat radiating efficiency. In addition, it is possible to sufficiently suppress a temperature rise locally or locally, and a combination with each of the above features is not essential.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Several embodiments of the present invention will be described below with reference to FIGS.

(Embodiment 1) The embodiment 1 is shown in FIG.
As schematically shown in FIG. 1, this is an example of the case of an AC type color plasma display panel A, which is used for a 42-inch type display, and is arranged vertically and horizontally in a plane corresponding to the size of a display screen. A heat dissipating member including: a panel main body including a plurality of discharge cells; and a heat dissipating member for dissipating heat received from the panel main body by applying a heat receiving portion to a back surface of the panel main body. 5 is the panel body 2
The heat receiving portion 3 applied to the panel main body 2 is joined to the support portion 7 at the back by an elastic member 8 so as to be supported in a predetermined contact state with the back surface of the panel main body 2.

The material and structure of the panel main body 2 vary depending on the type of the plasma display panel A and the performance required individually. In addition to the AC type color display panel A of the first embodiment, for example, a known DC A color plasma display panel of the same type as that of the conventional plasma display panel may be employed. In some cases, they may be different.

In the first embodiment, in particular, as shown in FIG. 2, the heat receiving portion 3 of the heat radiating member 5 has a very thin adhesive layer 11 at the portion facing the back surface of the panel main body 2. The heat receiving portion 3 of the member 5 has an elastic member 8 at a portion facing the panel main body 2 and the support portion 7 for fixing the heat radiating member 5, and the heat receiving portion 3 is pressed against the back surface of the panel main body 2 by the elastic member 8. ing. The heat receiving portion 3 and the back surface of the panel main body 2 may be brought into direct contact without interposing the adhesive layer 11. Each of the heat radiating members 5 applies heat to each heat receiving portion 3 when the heat receiving portion 3 is applied to the back surface of the panel main body 2 as shown in FIGS.
An elastic member 8 provided at a portion opposed to the supporting portion 7 presses the heat receiving portion 3 against the back surface of the panel main body 2 by elastic deformation as shown in FIG. Can be prevented, and the increase in heat transfer resistance from the panel body 2 to the heat receiving portion 3 due to the presence of air can be suppressed.

The elastic members 6 are individually provided in each of the heat receiving portions 3 so that the back surface of the panel main body 2 and the supporting portions 7 are provided.
2 can be elastically deformed according to the distance between the heat receiving portions 3 as required, and a minimum gap between the heat receiving portions 3 and the back surface of the panel body 2 when the elastic member 8 is not provided as shown in FIG. Up to 2 mm in thickness on the back of the panel body 2
Heat is transferred from the panel body 2 to the heat radiating member 5 due to the presence of the adhesive layer 11 because the elastic sheet is applied close to the back surface of the panel body 2 to about 1/10 of the case where the elastic sheet is applied. Can be minimized or eliminated, and the heat of each part of the panel main body 2 is quickly and efficiently transmitted to the corresponding part of the heat receiving part 3 of the heat radiating member 5, and the other parts of the heat receiving part 3 The heat is quickly dissipated from the heat dissipating portion 4 in many areas on the back of the heat receiving portion 3 while spreading quickly to the portion.

Thus, the local or overall temperature rise of the panel main body 2 is sufficiently suppressed, and the problems such as the thermal deterioration of the discharge cell 1 at an early stage and the occurrence of cracks in the panel main body 2 are solved. can do. At the same time, reducing the number of fans to reduce noise problems,
Alternatively, the problem of noise and the problem of maintenance due to the life of the bearing of the fan can be eliminated by eliminating the use of the fan.

More specifically, the panel body 2 has a thickness of about 5.5 mm and is made of a transparent material such as glass. Although not shown, the electric circuit for driving this and the circuit for electrically connecting the electrodes are in a tape shape, and the panel body 2
And project outward from the peripheral end face of each of them, and are arranged at intervals from each other. An electric circuit for driving may be formed by bending a flexible circuit along the side surface of the panel body 2, or
It is superimposed on the back surface of the panel body 2. The panel body 2 may be distorted due to heat when joining an upper substrate (not shown) and a lower substrate, and the difference between the center height and the peripheral height is about 4 mm. Correspondingly, the thickness of the elastic member 8 is also about 4 mm at the maximum.

The heat dissipating member 5 is preferably made of a material which has higher heat conduction than the panel body 2, is easy to process, and has excellent adhesiveness. For example, aluminum or an aluminum alloy is suitable. The heat receiving part 3 is formed in a plate-like member that is long in one direction,
The heat radiating portion 4 is integrally formed as a number of longitudinal fins 4a projecting rearward from the rear surface of the heat receiving portion 3 which is a plate-shaped member. The heat dissipating member 5 is preferably disposed on the entire back surface of the panel main body 2 or almost the entire surface excluding the periphery thereof. The heat dissipating member 5 is arranged vertically on the rear surface of the panel main body 2, horizontally arranged, vertically or horizontally. They are arranged like a grid.

The smaller the size of the grid, the better, for example, about 100 mm per side is sufficient.

Thus, as described above, the heat from the local area of the discharge cell 1 that emits light, particularly from the panel body 2, is partially transmitted to the corresponding portion of each of the heat receiving portions 3 of the arranged heat radiating member 5. This partial heat is quickly spread in the plate surface direction by each of the heat receiving portions 3 and is quickly radiated through the heat radiating portions 4 in many areas, and thus through many fins 4a.

The heat dissipating portion 4 is not limited to the fin shape as described above, and may be any shape or structure that increases the contact area with air, or any shape or structure that improves the flow of air. For example, it may be a thin plate having various shapes including fins, a cross section having a mountain shape or a wavy shape, a structure in which a thin flat plate is placed on these thin plates, a honeycomb structure, or the like. In addition to these, various shapes and structures for improving heat dissipation can be provided. The shape and structure of the heat radiating portion in various types of mechanical devices can be applied to these heat radiating shapes and heat radiating structures.

The supporting portion 7 has an opening 7a corresponding to the arrangement of the heat radiating members 5 so that the projecting portion of the heat radiating portion 4 from the heat receiving portion 3 projects into the space on the back side of the supporting portion 7. . The opening 7a is preferably small in order to release heat from the heat receiving portion 3 of the heat radiating member 5 by heat conduction from the heat receiving portion 3 to the support portion 7, and the abundance ratio of the support portion 7 is preferably increased. For example, when it is not necessary, the opening 7a can be made large as long as the heat radiating member can be supported via the heat receiving portion 3. Thus, the weight of the plasma display panel can be reduced. Further, the panel body 2 and the heat radiating member 5 can be integrated by other various methods such as by being sandwiched between fasteners and integrated.

The elastic member 8 is preferably made of a silicon-based resin because it has relatively high thermal conductivity and elasticity. In addition, since the adhesive layer 11 also has a relatively high thermal conductivity and elasticity, if an adhesive made of these materials or a double-sided adhesive tape is used, the heat receiving portion 3
Is bonded to the back surface of the panel body 2 to form a thermal bond, which makes it easier to perform subsequent operations such as improving the assemblability. As a result, the adhesiveness to the back surface of the cured panel main body 2 is increased due to the high adaptability to other shapes, and the heat transfer resistance from the panel main body 2 to the heat dissipation member 5 can be further reduced. This is advantageous for heat radiation of the panel body 2. In addition, when the adhesive is hardened later by a physical or chemical method, the bonding structure between the panel main body 2 and the heat radiating member 5 can be simplified or omitted. In the examples, good results were obtained by applying an adhesive to a thickness of about 0.1 mm or bonding with a double-sided adhesive tape of about 0.1 mm. Further, since the elastic member 8 has elasticity, it is possible to absorb a difference in the coefficient of thermal expansion between the panel body 2 and the heat radiating member 5 which is thermally joined to the panel body 2. It is possible to prevent the two from affecting each other due to the difference in shrinkage and causing the panel main body 2 to crack.

However, the elastic member 8 is effective even if it is not necessarily provided on the entire surface of the heat receiving portion 3 facing the support portion 7, and may have a discontinuous portion.

(Embodiment 2) In Embodiment 2, as shown in FIG. 3, a cross section in which the heat radiating portion 4 provided on the back of the heat receiving portion 3 of the heat radiating member 5 is applied to the back surface of the heat receiving portion 3 is shown. The point that it is constituted by a corrugated sheet 4b made of a corrugated metal sheet and a flat plate 4c made of a metal sheet placed on the back of the corrugated sheet 4b,
This is different from the first embodiment. Another structure is the first embodiment.
Therefore, the same members are denoted by the same reference numerals, and redundant description will be omitted.

Both the corrugated plate 4b and the flat plate 4c are made of aluminum having good thermal conductivity, and are integrated with the heat receiving portion 3 by welding, brazing, or bonding. In some cases, they may be integrated by a not-shown clamping structure or holding structure.

A heat radiating path 4d by a corrugated plate 4b is formed between the plate-shaped heat receiving portion 3 and the flat plate 4c. The heat radiating path 4d promotes natural convection of air, and can quickly radiate heat transmitted from the panel body 2 to the heat receiving unit 3 as in the first embodiment. Such a heat radiation path 4
In order to form d, the heat dissipating part 4 having a heat dissipating path of a honeycomb structure can be replaced. Also in this case, the honeycomb structure is preferably made of aluminum having good heat conductivity.

(Embodiment 3) In Embodiment 3, as shown in FIG. 4, a heat radiating member 5 has a heat radiating portion 4 in which a large number of fins 4a are integrally formed on the back of a plate-shaped heat receiving portion 3. Embodiment 4 is different from Embodiment 1 in that an elastic member 6 is baked on a portion facing the panel body 2. Since other configurations are the same, the same members are denoted by the same reference numerals, and redundant description will be omitted.

As described above, when the elastic member 6 is baked on the heat receiving portion 3 of the heat radiating member 5, the elastic member 6 and the heat receiving portion 3 are baked.
Since the heat transfer at the boundary portion 12 between the elastic member 6 and the elastic member 6 is not thinned until the gap between the heat receiving portion 3 and the back surface of the panel main body 2 is minimized, each part of the panel main body 2 Can be quickly and efficiently transmitted to the heat receiving portion 3 of the heat radiating member 5 to be radiated from the heat radiating portion 4,
Combined with good heat transfer in a close contact state by elasticity with the back surface of the panel main body 2, local or overall temperature rise of the panel main body 2 can be sufficiently suppressed. When the conditions for minimizing the gap are combined, the temperature rise can be further suppressed. As in the other embodiments, the elastic member 6 is preferably a silicon-based resin in terms of thermal conductivity and elasticity.

The heat dissipating member 5 adheres the heat receiving portion 3 to the back surface of the panel main body 2 with an adhesive 11 provided around the elastic member 6, and establishes a thermal bonding state in which the elastic member 6 is in close contact with the back surface of the panel main body 2. I'm trying to get. The adhesive 11 is also made of a silicon-based resin material, and the heat of the panel main body 2 is efficiently transmitted to the heat receiving portion 3 even in this portion. There is no loss.

The heat radiating portion 4 is replaced with a heat radiating portion formed by combining a corrugated plate and a flat plate, or a heat radiating portion having a honeycomb structure as described in the second embodiment. Is also good. The elastic member 6 and the adhesive 11 are preferably made of a silicon-based resin, but may be replaced with a resin material having good heat conductivity.

Fourth Embodiment A fourth embodiment is an example of a display having a plasma display panel. As shown in FIG. 5, the plasma display panel A and the driving of the plasma display panel A are shown in FIG. A flexible electric circuit B1 for electrically connecting the electric circuit B to the plasma display panel A and the electric circuit, and a cabinet for accommodating the electric circuit B and the flexible electric circuit B1 are provided. When used, a display D exhibiting the same functions and effects as those obtained by them is obtained. The flexible electric circuit B1 for connection is a tape-like circuit similar to that described in the first embodiment, and extends to the outside from the peripheral end surface of the panel main body 2 and is arranged with an interval therebetween.

The fourth embodiment is particularly characterized in that the heat radiating portion 4 of the heat radiating member 5 is projected outside the cabinet C as shown in FIG. The cabinet C is made of aluminum or the like, and has a window 21 for display by the panel body 2.
On the front side and a window 22 on the back side from which the heat radiating portion 4 protrudes. According to this, the radiator 4 is connected to the cabinet C
The panel body 2, the heat radiation member 5, and the outside air are radiated to the outside air through a short heat transfer path by directly touching the outside room temperature outside air, so that the heat radiation efficiency is improved, and the local and overall rise of the panel body 2 alone is achieved. The temperature can be sufficiently suppressed. Plasma display panel A as in first to third embodiments
According to the combination with, greatly reduces the number of fans used,
In some cases, it can be omitted.

The heat radiating section 4 of the fourth embodiment is the same as that of the first embodiment.
The vertical fins 4a are the same as in the case (1), and the air flow is easily generated by natural convection. The same operation and effect can be obtained even if a vertical heat radiation path is formed by the structure of the heat radiation part 4 as in the second and third embodiments. The depth of the cabinet C and the height at which the fins 4a protrude from the heat receiving portion 3 are set so that the distal ends of the fins 4a protrude rearward from the windows 22 of the cabinet C by a required amount. Vent holes (not shown) are provided on the upper and lower surfaces and side surfaces of the cabinet C, and air can be moved in and out through the vent holes.
The heat radiating portion 4 does not necessarily have to protrude outside the cabinet C when the heat radiating portion 4 alone or in combination with the plasma display panels A of the first to third embodiments satisfies the heat radiation characteristics.

[0042]

According to one feature of the plasma display panel of the present invention, the heat receiving portion of each heat dissipating member has an elastic member provided at an opposing portion of the heat dissipating member and a supporting portion for fixing the panel body. The deformation prevents the gap between the heat receiving portion and the back surface of the panel main body from being tightly adhered to the back surface of the panel main body, and furthermore, the elastic member in which each heat receiving portion is individually provided is deformed. When it is not provided, it is possible to reduce the heat transfer resistance from the panel main body to the heat receiving portion by applying it close to the rear surface of the panel main body to the minimum gap state that can be formed between the panel main body and the rear surface of the panel main body. Accordingly, the heat of each part of the panel main body is quickly and efficiently transmitted to the corresponding portion of the heat receiving portion of the heat radiating member, and the heat radiating portion of many regions on the back of the heat receiving portion while rapidly spreading to other portions of the heat receiving portion. Promptly Since the heat is dissipated, the local or overall temperature rise of the panel body is sufficiently suppressed to solve the problem that the discharge cell is thermally deteriorated early or the panel body is cracked. be able to. At the same time, the number of fans is reduced to reduce the noise problem, or the fan need not be used, thereby eliminating the noise problem and the maintenance problem due to the fan bearing life. be able to.

According to another feature of the plasma display panel of the present invention, since the elastic member is baked on the heat receiving portion of the heat radiating member, heat transfer at the boundary between the elastic member and the heat receiving portion is efficiently performed. Therefore, even if the elastic member is not thinned by that much until the gap between the heat receiving portion and the back surface of the panel main body is minimized, the heat of each portion of the panel main body is quickly transmitted to the corresponding portion of the heat receiving portion of the heat radiating member. The transmission can be performed efficiently, and the local or overall temperature rise of the panel main body can be sufficiently suppressed as in the case described above. If conditions for minimizing the gap are combined, it is possible to further suppress the temperature rise of the panel body partially and entirely.

If a plasma display panel having these features, an electric circuit for driving the plasma display panel, and a cabinet for accommodating the plasma display panel and the electric circuit are provided, a display exhibiting the same operation and effect can be obtained. can get.

In such a case as well, if the heat radiating portion of the heat radiating member projects outside the cabinet, the heat radiating portion directly contacts the room temperature air outside the cabinet to improve the heat radiating efficiency. In addition, it is possible to sufficiently suppress a temperature rise locally or locally, and a combination with each of the above features is not essential.
