Meanwhile, in the structure as in the display apparatus described in PTL 1, a gap is formed between the bezel and an outer peripheral surface of the display, whereby foreign matters such as dust may enter the gap. This may degrade quality.
Since the gap is present between the bezel and the outer peripheral surface of the display, a viewer visually recognizes the gap. This may degrade a design property.
Particularly, since the gap is present on an outer periphery side of the display surface when an image or a video displayed on the display is visually recognized, the gap tends to be conspicuous. This may degrade the design property upon visually recognizing the image or the video.

Note that effects described in the specification are illustrative in nature and not limited, and other effects may be provided.
Hereinafter, an exemplary embodiment of a display apparatus of the present technology will be described with reference to the attached drawings.
The exemplary embodiment described below is a case where the display apparatus of the present technology is applied to a television receiver in which an image is displayed on its display.
Note that a range to which the present technology is applied is not limited to the television receiver, and the present technology can widely be applied to various display apparatuses such as a monitor used in, for example, a personal computer.
In the following description, a direction in which a display surface of the display apparatus (television receiver) is directed is defined as a front direction, and then front-rear, upper-lower, and left-right directions are represented. Note that the front-rear, upper-lower, and left-right directions described below are set for convenience of the description, and implementation of the present technology is not limited to those directions.
<Configuration of Display Apparatus>
A display apparatus (television receiver) 1 is formed in, for example, a substantially rectangle shape that is horizontally long and whose thickness in the front-rear direction is thin (refer to
The display apparatus 1 includes a display 2 on which an image is displayed, a back chassis 3 disposed behind the display 2, a heat radiation plate 4 internally disposed, a sealing body 5 positioned on an outer periphery side of the heat radiation plate 4, and an outer frame 6 disposed on an outer periphery side of the display 2 and the back chassis 3 (refer to
The display 2 is formed in a plate shape directed in the front-rear direction, and is configured with an organic EL (Electro Luminescence) display of a light emission type that emits light by using an organic light-emitting phenomenon, for example. The display 2 includes a substrate 7 and a polarization film 8 stuck on a front surface and an outer peripheral surface of the substrate 7. A front surface of the display 2 serves as a display surface 2a that displays the image.
The display 2 is configured by laminating various layers such as a support layer, a display layer, an insulation layer, and a protection layer, and includes a plurality of driving elements and a plurality of light-emitting elements, which are respectively arranged in a matrix. Each light-emitting element emits light toward the front by being driven by a corresponding driving element, and includes a red light-emitting element, a green light-emitting element, and a blue light-emitting element, for example.
The display 2 includes a color filter. Light rays respectively emitted by the red light-emitting element, the green light-emitting element, and the blue light-emitting element pass through corresponding portions of the color filter to advance forward through the polarization film 8.
The back chassis 3 is formed in a flat-plate shape whose outer shape is substantially the same size as that of the display 2 by using glass, for example. The back chassis 3 includes glass having the flat-plate shape, thereby securing increased strength even in a case where the back chassis 3 is made thin. This can achieve improvement of strength of the display apparatus 1 and thinning of the display apparatus 1.
Note that a glass scattering prevention film may be stuck on a rear surface of the back chassis 3, for example.
An outer shape of the heat radiation plate 4 is made smaller than that of the display 2, and the heat radiation plate 4 is disposed between the display 2 and the back chassis 3. For example, the heat radiation plate 4 includes a metal material such as aluminum, and has a function for radiating heat generated in the display 2.
For example, the heat radiation plate 4 is stuck on a portion in a rear surface 2b of the display 2 excluding an outer peripheral portion by using adhesive tapes 9, 9, . . . such as double sided tapes. The adhesive tapes 9 are desirably including a material having high thermal conductivity.
Note that the heat radiation plate 4 may detachably be attached to the display 2 by using another means other than the adhesive tapes 9 to allow the heat radiation plate 4 to be separated from the display 2. In this case, a cushion having thermal conductivity may be disposed between the display 2 and the heat radiation plate 4, and the heat radiation plate 4 may be pressed against the display 2 through the cushion.
For example, the heat radiation plate 4 is stuck on a portion in a front surface 3a of the back chassis 3 excluding an outer peripheral portion by using adhesive tapes 10, 10, . . . such as the double sided tapes.
An outer shape of the sealing body 5 is made substantially the same as that of the display 2, and an inner shape of the sealing body 5 is made slightly larger than the heat radiation plate 4. The sealing body 5 includes a material having elasticity, for example, silicon. An outer peripheral portion in the rear surface 2b of the display 2 is pressed against a front surface 5a of the sealing body 5, and the display 2 is brought into close contact with the sealing body 5 in a separable manner. A rear surface 5b of the sealing body 5 is stuck on the outer peripheral portion in the front surface 3a of the back chassis 3 by using, for example, an adhesive tape 11 such as the double sided tape, which is formed in a frame shape. An outer peripheral portion of the display 2 is pressed against the sealing body 5. Therefore, the sealing body 5 is elastically deformed.
As described above, the sealing body 5 formed in the frame shape is stuck on the outer peripheral portion of the back chassis 3 by using the adhesive tape 11, and the outer peripheral portion of the display 2 is pressed against the front surface 5a of the sealing body 5. This allows the sealing body 5 to seal a space 12 between the display 2 and the back chassis 3.
The outer frame 6 is provided as a resin portion 13 that is entirely including a resin material, for example. An inner peripheral surface 6a of the outer frame 6 is brought into close contact with an outer peripheral surface 2c of the display 2, an outer peripheral surface 3c of the back chassis 3, and an outer peripheral surface 5c of the sealing body 5. Accordingly, in the outer frame 6, an inner peripheral surface 13a of the resin portion 13 is brought into close contact with the outer peripheral surface 3c and the outer peripheral surface 5c. In the outer frame 6, an outer peripheral surface 6b is formed into a curved surface shape projecting outward, for example.
The outer frame 6 is, for example, formed such that a base material having fluidity is filled on an outer periphery side of the display 2, the back chassis 3, and the sealing body 5, and after the base material is cooled and solidified, the base material is processed into a predetermined shape by cutting. In this manner, the outer frame 6 is formed by being filled with the base material having fluidity. This allows the inner peripheral surface 6a to be formed in a shape following the outer peripheral surface 2c of the display 2, the outer peripheral surface 3c of the back chassis 3, and the outer peripheral surface 5c of the sealing body 5. The inner peripheral surface 6a is thus brought into close contact with the outer peripheral surface 2c of the display 2, the outer peripheral surface 3c of the back chassis 3, and the outer peripheral surface 5c of the sealing body 5.
Accordingly, in the display apparatus 1, due to close contact between the inner peripheral surface 6a of the outer frame 6 and the outer peripheral surface 2c of the display 2, no gap is present between the outer frame 6 and the display 2. Further, due to close contact between the inner peripheral surface 6a of the outer frame 6 and the outer peripheral surface 3c of the back chassis 3, no gap is also present between the outer frame 6 and the back chassis 3.
Furthermore, along a thickness direction (front-rear direction) of the display apparatus 1, a size (a width in the front-rear direction) of the outer frame 6 is made the same as a distance from the display surface 2a of the display 2 to the rear surface 3b of the back chassis 3.
Note that the outer frame 6 is formed by being filled with the base material having fluidity as described above, thereby allowing a reduction in manufacturing cost in comparison with a structure in which a bezel including, for example, metal or resin is attached to the outer peripheral portion and the like of the display 2.
As described above, the display apparatus 1 is provided with the outer frame 6 that is includes the resin material and covers the display 2 and the back chassis 3 from the outer periphery side. The inner peripheral surface 13a of the resin portion 13 of the outer frame 6 is brought into close contact with the outer peripheral surface 2c of the display 2 and the outer peripheral surface 3c of the back chassis 3.
Accordingly, along the direction orthogonal to the thickness direction of the display 2, no gap is produced between the outer frame 6 and the display 2 and between the outer frame 6 and the back chassis 3, whereby foreign matters such as dust do not enter between the outer frame 6 and the display 2 and between the outer frame 6 and the back chassis 3. This can achieve improvement of quality of the display apparatus 1.
Furthermore, along the direction orthogonal to the thickness direction of the display 2, no gap is produced between the outer frame 6 and the display 2, and the outer frame 6 can be made transparent or colorized in any color, thereby enhancing freedom of design. This can achieve improvement of the design property.
Furthermore, along the direction orthogonal to the thickness direction of the display 2, no gap is produced between the outer frame 6 and the display 2 and between the outer frame 6 and the back chassis 3, and the outer frame 6 is positioned on the outer periphery side of the display 2 and the back chassis 3. Therefore, the display apparatus 1 is not increased in size along the thickness direction (front-rear direction) and the direction orthogonal to the thickness direction, thereby allowing a reduction in size of the display apparatus 1.
Furthermore, the outer frame 6 is positioned on the outer periphery side of the display 2 and the back chassis 3 over entire peripheries while being brought into close contact with the display 2 and the back chassis 3, thereby allowing rigidity of the display apparatus 1 to be increased. This can achieve improvement of quality of the display apparatus 1.
Furthermore, the sealing body 5 is formed in the frame shape, and the space 12 between the display 2 and the back chassis 3 is sealed by the sealing body 5, thereby preventing the resin material before being cured from entering the space 12 by the sealing body 5, in a case where the outer frame 6 includes a curing type resin material. This can protect structures disposed between the display 2 and the back chassis 3.
Furthermore, the outer peripheral surface 6b of the outer frame 6 is formed in the curved surface shape projecting outward, thereby allowing the outer peripheral surface 6b of the outer frame 6 to be formed in a shape having no edge. Therefore, a user does not have uncomfortable feeling, when the user touches the outer frame 6. This can achieve improvement of quality of the display apparatus 1.
Note that the outer frame 6 may be colorized, or the outer frame 6 may be colored, or colorless and transparent. When the outer frame 6 is made transparent, a person who visually recognizes the display surface 2a hardly feels presence of the outer frame 6, and tends to visually recognize as if no structure is present outside the image or the video displayed on the display surface 2a. This can achieve improvement of visibility of the image or the video.
Note that the outer frame 6 may be colorized, or the outer frame 6 may be colored, or colorless and transparent. When the outer frame 6 is made transparent, a person who visually recognizes the display surface 2a hardly feels presence of the outer frame 6, and tends to visually recognize as if no structure is present outside the image or the video displayed on the display surface 2a. This can achieve improvement of visibility of the image or the video.
<Modifications>
Hereinafter, various modifications of the outer frame 6 or other components will be described (refer to
Note that for the various modifications described below, only parts different from the display apparatus 1 will be described in detail, and description of other parts is omitted while attaching reference signs identical to those attached to identical parts in the display apparatus 1.
First, a first modification will be described (refer to
The outer frame 6A is configured with a resin portion 13A including a resin material, and an integrally-formed portion 14 integrally formed with the resin portion 13A by, for example, insert molding. The integrally-formed portion 14 is positioned at an intermediate portion of the outer frame 6A in the front-rear direction, for example. The resin portion 13A is disposed at front and rear portions of the integrally-formed portion 14 in the front-rear direction. In the outer frame 6A, the resin portion 13A is brought into close contact with the outer peripheral surface 2c of the display 2, the outer peripheral surface 3c of the back chassis 3, and the outer peripheral surface 5c of the sealing body 5, and the integrally-formed portion 14 is also partly brought into close contact with the outer peripheral surface 3c of the back chassis 3. An outer peripheral surface 6b of the outer frame 6A is formed in a curved surface shape projecting outward, for example.
The integrally-formed portion 14 includes a material different in composition or kind from the resin portion 13A. The material of the integrally-formed portion 14 may be resin, metal, or a material other than resin and metal.
For example, the outer frame 6A is formed such that in a state where the integrally-formed portion 14 is attached to the back chassis 3, a base material having fluidity for forming the resin portion 13A is filled on an outer periphery side of the display 2, the back chassis 3, and the sealing body 5, and after the base material is cooled and solidified, the base material is processed in a predetermined shape by cutting.
As described above, the integrally-formed portion 14 including the material different in composition or kind from the resin portion 13A is provided to the outer frame 6A, together with the resin portion 13A. The providing the resin portion 13A and the integrally-formed portion 14 to the outer frame 6A allows the resin portion 13A and the integrally-formed portion 14 to respectively have functions different from each other according to compositions and kinds. This can achieve improvement of functionality of the outer frame 6A.
For example, when rigidity of the integrally-formed portion 14 is made higher than rigidity of the resin portion 13A, rigidity of the outer frame 6A as a whole is made higher. This can protect the display 2 and the back chassis 3 in a stable state.
Furthermore, when the resin portion 13A and the integrally-formed portion 14 are made to have different colors, or one of the resin portion 13A and the integrally-formed portion 14, which has been made transparent, is made opaque, freedom of design is enhanced. This can achieve improvement of the design property.
Next, a second modification will be described (refer to
The portion continuous to the integrally-formed portion 14 is provided as a continuous portion 15, and the continuous portion 15 protrudes from the integrally-formed portion 14 toward the space 12 that is present on an inner side. The integrally-formed portion 14 and the continuous portion 15 are integrally provided as portions of an insert member 16. In the insert member 16, the continuous portion 15 is stuck on the outer peripheral portion in the front surface 3a of the back chassis 3 by, for example, adhesive tapes 17, 17, . . . such as the double sided tapes.
Accordingly, in a case where the insert member 16 is used, it is unnecessary for the integrally-formed portion 14 to be attached to the back chassis 3.
A sealing body 5B is disposed between the display 2 and the continuous portion 15. The sealing body 5B is fixed such that the rear surface 5b is stuck on an outer peripheral portion in a front surface 15a of the continuous portion 15 by, for example, an adhesive tape 11. An outer peripheral portion of the display 2 is pressed against a front surface 5a of the sealing body 5B.
The insert member 16 includes a material different in composition or kind from the resin portion 13A. The material of the insert member 16 may be resin, metal, or a material other than resin and metal.
For example, the insert member 16 is formed such that in a state where the continuous portion 15 is attached to the back chassis 3, a base material having fluidity for forming the resin portion 13A is filled on an outer periphery side of the display 2, the back chassis 3, and the sealing body 5B, and after the base material is cooled and solidified, the base material is processed in a predetermined shape by cutting.
As described above, the insert member 16 including the integrally-formed portion 14 is provided, and the insert member 16 is provided with the continuous portion 15 that is continuous to the integrally-formed portion 14 and is positioned between the display 2 and the back chassis 3, thereby positioning the continuous portion 15 between the display 2 and the back chassis 3.
Accordingly, the continuous portion 15 retains a predetermined interval between the display 2 and the back chassis 3, and therefore, a proper positional relationship between the display 2 and the back chassis 3 can be retained.
Further, the continuous portion 15 can be used as a portion that has a function similar to or different from that of the integrally-formed portion 14. This can achieve improvement of the functionality of the display apparatus 1.
Furthermore, since the continuous portion 15 is fixed to the back chassis 3, a positional relationship of the integrally-formed portion 14 and the continuous portion 15 with respect to the back chassis 3 does not change. This allows the outer frame 6A to be stably brought into close contact with the back chassis 3.
Note that, in the second modification, a continuous portion 15B may be provided so as to be brought into close contact with the rear surface 2b of the display 2 without providing the sealing body 5B (refer to
By providing the above-described continuous portion 15B, the continuous portion 15B is used as the sealing body, and the space 12 between the display 2 and the back chassis 3 is sealed by the continuous portion 15B. Therefore, it is unnecessary to provide a dedicated sealing body, thereby achieving a reduction in part count.
Next, a third modification will be described (refer to
For example, the back chassis 3 is configured to be transparent. An arrangement hole 3d penetrating the back chassis 3 in the front-rear direction is formed at a position close to a lower end of the back chassis 3.
The circuit board 18 is attached to the rear surface 3b of the back chassis 3 while being directed along the front-rear direction, and a light source 19 is mounted on the circuit board 18. A light emitting diode (LED) is used as the light source 19. The light source 19 is positioned in the arrangement hole 3d.
The outer frame 6D is configured as a resin portion 13D entirely including a transparent resin material, for example, and has a reflection surface 20 that internally reflects light at a position immediately below the back chassis 3.
Light is emitted downwardly from the light source 19, and the emitted light enters the inside of the back chassis 3. The light that has entered the inside of the back chassis 3 is downwardly guided by the back chassis 3, enters the outer frame 6D, is forwardly reflected on the reflection surface 20, and is emitted from the outer frame 6D toward the front. Accordingly, the back chassis 3 and the outer frame 6D function as a light-guiding body that guides light along a predetermined direction.
Such a configuration is preferable as, for example, a configuration in which the light from the light source 19 is used to indicate, for example, power on/off or mode-setting states depending on turning on/off of the light, is used for illumination light, or is used as detection light for, for example, a motion detector or an illuminance sensor to control, for example, power on/off or illuminance depending on a distance to a person.
As described above, the outer frame 6D is used as the light-guiding body that guides light, whereby the light is guided by the outer frame 6D. This can achieve improvement of freedom of an arrangement position of each member related to light such as the circuit substrate 18 or the light source 19, and improvement of functionality of the outer frame 6D.
In addition, it is unnecessary to provide a dedicated light-guiding body that guides light, thereby achieving a reduction in parts count of the display apparatus 1.
Furthermore, the outer frame 6D is formed with the reflection surface 20 that internally reflects light that has entered the outer frame 6D, whereby the light is reflected by the outer frame 6D. This can achieve further improvement of freedom of the arrangement position of each member related to light such as the circuit substrate 18 or the light source 19, and further improvement of the functionality of the outer frame 6D.
In addition, it is unnecessary to provide the dedicated reflection body that reflects light, thereby achieving a further reduction in parts count of the display apparatus 1.
Furthermore, the back chassis 3 is also used as the light-guiding body that guides light, whereby the light is guided by the back chassis 3. This can achieve further improvement of freedom of the arrangement position of each member related to light such as the circuit substrate 18 or the light source 19, and further improvement of functionality of the back chassis 3.
In addition, it is unnecessary to provide the dedicated light-guiding body that guides light, thereby achieving a further reduction in parts count of the display apparatus 1.
Note that, the above third modification describes an example in which the reflection surface 20 is formed in the outer frame 6D entirely provided as the resin portion 13D. However, an outer frame 6E can be used in place of the outer frame 6D (refer to
In a case where the outer frame 6E is provided, light emitted downwardly from the light source 19 enters the outer frame 6E from the inside of the back chassis 3, is reflected forwardly on the reflection surface 20 of the outer frame 6E, and is emitted from the outer frame 6E toward the front. Accordingly, the back chassis 3 and the outer frame 6E function as the light-guiding body that guides light along the predetermined direction in this case.
The above third modification describes an example in which the circuit board 18 is attached to the rear surface 3b of the back chassis 3 while being directed along the front-rear direction, and light is emitted downwardly from the light source 19. However, the direction of the circuit board 18 is changed, and light can be configured to be emitted downwardly from the light source 19 as described below (refer to
For example, the circuit board 18 can be directed along the upper-lower direction using a bracket 21 (refer to
The circuit board 18 is held in the case 22 while being directed along the upper-lower direction, and the light source 19 is mounted on a lower surface of the circuit board 18. The attachment target portion 23 of the bracket 21 is attached to the rear surface 3b of the back chassis 3, and a part of the case 22, a part of the circuit board 18, and the light source 19 are positioned in the arrangement hole 3d.
Light is emitted downwardly from the light source 19, and the emitted light enters the inside of the back chassis 3.
Furthermore, for example, the circuit board 18 can be directed along the upper-lower direction using a bracket 24 (refer to
The circuit board 18 is held in the case 25 while being directed along the upper-lower direction, and the light source 19 is mounted on the lower surface of the circuit board 18. A front end of the case 25 of the bracket 24 is inserted into the arrangement hole 3d and is attached to the continuous portion 15. A front end of the circuit board 18 is also attached to the continuous portion 15.
The front end of the case 25 and the front end of the circuit board 18 are attached to the continuous portion 15, thereby positioning a part of the case 25 in the arrangement hole 3d together with the light source 19. Light is emitted downwardly from the light source 19, and the emitted light enters the inside of the back chassis 3.
Note that the above third modification describes an example in which the light emitted downwardly from the light source 19 is emitted from a lower end portion of the outer frame 6, 6D, and 6E. However, the display apparatus 1 can be configured such that light emitted upwardly or laterally from the light source 19 is emitted from an upper end portion or lateral side portions of the outer frame 6, 6D, and 6E.
Subsequently, a fourth modification will be described (refer to
The arrangement hole 3d penetrating the back chassis 3 along the front-rear direction is formed at a position close to a lower end of the back chassis 3.
The circuit board 18 is attached to the rear surface 3b of the back chassis 3 while being directed along the front-rear direction, and the light source 19 is mounted on the circuit board 18. The light source 19 is positioned in the arrangement hole 3d.
The continuous portion 15F is provided so as to be continuous to the integrally-formed portion 14E of the outer frame 6E, and the integrally-formed portion 14E and the continuous portion 15F are provided as portions of an insert member 16F. The outer frame 6E and the continuous portion 15F are made transparent, for example. A reflection surface 26 that internally reflects light is provided at an end, of the continuous portion 15F, opposite to the integrally-formed portion 14E.
Light is emitted forwardly from the light source 19, and the emitted light enters the inside of the continuous portion 15F. The light that has entered the inside of the continuous portion 15F is reflected downwardly on the reflection surface 26, is guided downwardly by the continuous portion 15F and the integrally-formed portion 14E, is reflected forwardly on the reflection surface 20, and is emitted from the outer frame 6E toward the front. Accordingly, the continuous portion 15F and the outer frame 6E function as the light-guiding body that guides light along a predetermined direction.
As described above, the continuous portion 15F is used as the light-guiding body that guides light, whereby the light is guided by the continuous portion 15F. This can achieve improvement of freedom of an arrangement position of each member related to light such as the circuit substrate 18 or the light source 19, and improvement of functionality of the continuous portion 15F.
In addition, it is unnecessary to provide the dedicated light-guiding body that guides light, thereby achieving a reduction in parts count of the display apparatus 1.
Furthermore, the continuous portion 15F is formed with the reflection surface 26 that internally reflects light, whereby the light is reflected by the continuous portion 15F. This can achieve further improvement of freedom of the arrangement position of each member related to light such as the circuit substrate 18 or the light source 19, and further improvement of the functionality of the continuous portion 15F.
In addition, it is unnecessary to provide the dedicated reflection body that reflects light, thereby achieving a further reduction in parts count of the display apparatus 1.
Note that the above fourth modification describes an example in which the circuit board 18 is attached to the rear surface 3b of the back chassis 3 while being directed along the front-rear direction, and light is emitted forwardly from the light source 19. However, a configuration in which the circuit board 18 is directed along the upper-lower direction, and light is emitted downwardly from the light source 19 can be used (refer to
For example, the circuit board 18 can be directed along the upper-lower direction using a bracket 27. The bracket 27 includes a case 28 opening downwardly and an attachment target portion 29 that protrudes upward from a rear end of the case 28.
The circuit board 18 is held in the case 28 while being directed along the upper-lower direction, and the light source 19 is mounted on the lower surface of the circuit board 18. The attachment target portion 29 of the bracket 27 is attached on the rear surface 3b of the back chassis 3, and a front half portion of the case 28 is inserted into the arrangement hole 3d. The light source 19 is then positioned immediately above the continuous portion 15.
Light is emitted downwardly from the light source 19, and the emitted light enters the inside of the continuous portion 15.
Note that the above fourth modification describes an example in which the light is emitted from the lower end portion of the outer frame 6E. However, the display apparatus 1 can be configured such that light from the light source 19 is emitted from an upper end portion or lateral side portions of the outer frame 6E.
Furthermore, the above modification describes an example in which the light emitted from the light source 19 is reflected. However, for example, a configuration in which the light emitted from the light source 19 is diffused in the outer frame 6, 6D, and 6E, and therefore the outer frame 6, 6D, and 6E looks like shining can be achieved.
<Others>
For example, the display apparatus 1 can be configured such that infrared light emitted from an infrared-light emission portion 50 of, for example, a remote control device is guided to a light reception portion of, for example, a sensor along a predetermined route, to perform a predetermined function (refer to
For example, the infrared light can be configured so as to enter the outer frame 6D, to be reflected on the reflection surface 20, to be guided through the inside of the back chassis 3, and to enter a predetermined light reception portion. In this case, the outer frame 6D and the back chassis 3 function as the light-guiding body.
Note that the light-guiding body that guides the infrared light is not limited to the outer frame 6D and the back chassis 3, and for example, the outer frame 6E or the continuous portion 15, 15B, and 15F can be used.
<Application to Another Display Apparatus>
An example in which the present technology is applied to the display apparatus 1 that uses the organic EL display is described above. However, the present technology is applicable to another kind of display apparatus that uses a display other than the organic EL display.
For example, the present technology is also applicable to a display apparatus 1X that uses a liquid crystal display described below (refer to
For example, the display apparatus (television receiver) 1X includes a display 52, a back chassis 53, a heat radiation plate 54, a sealing body 55, and an outer frame 56. The display 52 is formed in a substantially rectangular shape that is horizontally long and whose thickness along the front-rear direction is thin, and displays an image. The back chassis 53 is disposed behind the display 52. The heat radiation plate 54 is internally disposed. The sealing body 55 is positioned on an outer periphery side of the radiation plate 54. The outer frame 56 is disposed on an outer periphery side of the display 52 and the back chassis 53.
The display 52 is the liquid crystal display, and is formed in a plate shape directed along the front-rear direction. The display 52 includes a substrate 57 and a polarization film 58 stuck on a front surface and an outer peripheral surface of the substrate 57. A front surface of the display 52 serves as a display surface 52a on which an image is displayed.
For example, the back chassis 53 includes glass and has an outer shape formed in a flat-plate shape having a substantially the same size as that of the display 52. A flat-shaped glass is used as the back chassis 53, thereby securing increased strength even in a case where the back chassis 53 is made thin. This can achieve improvement of strength of the display apparatus 1X and thinning of the display apparatus 1X.
Note that the glass scattering prevention film may be stuck on a rear surface of the back chassis 53, for example.
An outer shape of the heat radiation plate 54 is made smaller than that of the display 52. The heat radiation plate 54 is disposed between the display 52 and the back chassis 53, and is attached to a portion in a front surface 53a of the back chassis 53 excluding an outer periphery portion, for example. The heat radiation plate 54 includes, for example, a metal material such as aluminum, and has a function for dissipating heat generated in the display 52.
A reflection plate 59 is attached to a front surface of the heat radiation plate 54.
A light-guiding plate 60 is disposed between the back chassis 53 and the display 52. The light-guiding plate 60 includes a resin material such as acrylic or a glass material. The reflection plate 59 is attached to a rear surface of the light-guiding plate 60.
An optical sheet 61 is stuck on a front surface of the light-guiding plate 60. The optical sheet 61 is configured with various kinds of functional sheets laminated along the front-rear direction. The optical sheet 61 is configured with, for example, a polarizable sheet, a prism sheet, a diffusion sheet, and a reflection sheet, which are laminated.
A light source unit 62 is disposed on an outer periphery side of the light-guiding plate 60. The light source unit 62 includes control substrates 63, 63, . . . disposed along an outer peripheral surface of the light-guiding plate 60, and backlight light sources 64, 64, . . . mounted on the control substrates 63, 63, . . . while being separated from each other along a longitudinal direction of the control substrates 63, 63, . . .
The control substrates 63, 63, . . . are attached to a not-illustrated bracket fixed to, for example, the back chassis 53. The backlight light sources 64, 64, . . . are positioned between the control substrates 63 and the outer peripheral surface of the light-guiding plate 60. For example, light emitting diodes (LEDs) are used as the backlight light sources 64.
An outer shape of the sealing body 55 is made substantially the same as that of the display 52, and an inner shape of the sealing body 55 is made slightly larger than the heat radiation plate 54. The sealing body 55 includes an elastic material, for example, silicon. An outer peripheral portion in a rear surface 52b of the display 52 is pressed against a front surface 55a of the sealing body 55. The display 52 is brought into close contact with the sealing body 55 in a separable state. A rear surface 55b of the sealing body 55 is attached to an outer peripheral portion in the front surface 53a of the back chassis 53. The outer peripheral portion of the display 52 is pressed against the sealing body 55, so that the sealing body 55 is elastically deformed.
As described above, the sealing body 55 formed in the frame shape is attached to the outer peripheral portion of the back chassis 53, and the outer peripheral portion of the display 52 is pressed against the front surface 55a of the sealing body 55. This causes the sealing body 55 to seal a space 65 between the display 52 and the back chassis 53.
The outer frame 56 is provided as a resin portion 66 entirely including a resin material, for example. An inner surface 56a of the outer frame 56 is brought into close contact with an outer peripheral surface 52c of the display 52, an outer peripheral surface 53c of the back chassis 53, and an outer peripheral surface 55c of the sealing body 55. Accordingly, in the outer frame 56, an inner peripheral surface 66a of the resin portion 66 is brought into close contact with the outer peripheral surface 52c, the outer peripheral surface 53c, and the outer peripheral surface 55c. An outer peripheral surface 56b of the outer frame 56 is formed in a curved surface shape projecting outward, for example.
For example, the outer frame 56 is formed such that a base material having fluidity is filled on an outer periphery side of the display 52, the back chassis 53, and the sealing body 55, and after the base material is cooled and solidified, the base material is processed in a predetermined shape by cutting. As described above, the outer frame 56 is filled with the base material having fluidity, and therefore the inner peripheral surface 56a is formed in a shape following the outer peripheral surface 52c of the display 52, the outer peripheral surface 53c of the back chassis 53, and the outer peripheral surface 55c of the sealing body 55. Therefore, the inner peripheral surface 56a is brought into close contact with the outer peripheral surface 52c of the display 52, the outer peripheral surface 53c of the back chassis 53, and the outer peripheral surface 55c of the sealing body 55.
Accordingly, in the display apparatus 1X, the inner peripheral surface 56a of the outer frame 56 is brought into close contact with the outer peripheral surface 52c of the display 52, thereby producing no gap between the outer frame 56 and the display 52. Further, the inner peripheral surface 56a of the outer frame 56 is brought into close contact with the outer peripheral surface 53c of the back chassis 53, thereby also producing no gap between the outer frame 56 and the back chassis 53.
In addition, in the display apparatus 1X, in a thickness direction (front-rear direction), a size (a width in the front-rear direction) of the outer frame 56 is made the same as a distance from the display surface 52a of the display 52 to the rear surface 53b of the back chassis 53.
In the display apparatus 1X, when an image or a video is displayed on the display surface 52a of the display 52, light is emitted from the backlight light sources 64, 64, . . . .
The light emitted from the backlight light sources 64, 64, . . . enters the light-guiding plate 60, and is guided through the inside of the light-guiding plate 60 to be emitted toward the front. At this time, a part of the light that has entered the light-guiding plate 60 is reflected by the reflection plate 59, and is emitted toward the front. The light emitted from the light-guiding plate 60 toward the front enters the display 52 as backlight while being controlled by the optical sheet 61.
As described above, in the display apparatus lx, the outer frame 56 that includes the resin material and covers the display 52 and the back chassis 53 from an outer periphery side is provided, and the inner peripheral surface 56a of the resin portion 66 of the outer frame 56 is brought into close contact with the outer peripheral surface 52c of the display 52 and the outer peripheral surface 53c of the back chassis 53.
Accordingly, no gap is produced between the outer frame 56 and the display 52 and between the outer frame 56 and the back chassis 53 along the direction orthogonal to the thickness direction of the display 52. Therefore, foreign matters such as dust do not enter between the outer frame 56 and the display 52 and between the outer frame 56 and the back chassis 53. This can achieve improvement of quality.
In addition, no gap is produced between the outer frame 56 and the display 52 along the direction orthogonal to the thickness direction of the display 52, and the outer frame 56 can be made transparent or can be colorized in any color, thereby enhancing freedom of design. This can achieve improvement of the design property.
Furthermore, no gap is produced between the outer frame 56 and the display 52 and between the outer frame 56 and the back chassis 53 along the direction orthogonal to the thickness direction of the display 52, and the outer frame 56 is positioned on the outer periphery side of the display 52 and the back chassis 53, thereby preventing the display apparatus 1X from being increased in size along the thickness direction (front-rear direction) and the direction orthogonal to the thickness direction. This can achieve a reduction in size of the display apparatus 1X.
In addition, the outer frame 56 is positioned on the outer periphery side over entire peripheries of the display 52 and the back chassis 53 in a state where the outer frame 56 is brought into close contact with the display 52 and the back chassis 53. This can enhance rigidity of the display apparatus 1X so that the quality can be improved.
Note that, respective configurations in the first modification to the fourth modification can also be applied to the display apparatus 1X, similar to the above-described display apparatus 1.
