DETAILED DESCRIPTION

Hereinafter, a display apparatus according to an embodiment of the present technology will be explained with reference to attached drawings.

The display apparatus according to the embodiment of the present technology shown below is applied to a television receiver displaying images on a liquid crystal panel functioning as a display.

The application range of the present technology is not limited to the television receiver using the liquid crystal panel as the display but the present technology can be widely applied to various types of display apparatuses such as other various types of television receivers in any kind of display and monitors used for a personal computer and so on.

[Structure of Display Apparatus]

A display apparatus (television receiver)1is provided with an apparatus body2which is formed in a landscape, flat and approximately rectangular shape, and the apparatus body2includes a back chassis3, a display4and a rear cover5(refer toFIG. 1toFIG. 4).

The back chassis3is made of an iron material, which is formed in a landscape, rectangular and approximately flat-plate shape facing the front and back, having a thickness of, for example, 0.5 mm. As the iron material is relatively lower in price than other metal materials, it is possible to reduce manufacturing costs when the back chassis3is formed by using the iron material.

An outer peripheral portion other than a lower end portion in the back chassis3is provided as a first reinforcing portion6protruding forward as compared with an inner portion of the back chassis3(refer toFIG. 5andFIG. 6).

In the back chassis3, second reinforcing portions7,8,9and9having a portrait and approximately rectangular shape protruding forward are respectively provided at positions of a center portion in right and left directions and both sides of right and left. The second reinforcing portions7and8are provided in the center portion of the back chassis3apart from each other in a vertical direction, while the second reinforcing portions9and9are provided on right and left of the second reinforcing portions7and8respectively.

In the back chassis3, plural through holes3a,3a, . . . piercing in front and back directions are respectively formed at areas where the second reinforcing portions7,9and9are provided. The through holes3a,3a, . . . are positioned, for example, at equal intervals.

In the back chassis3, third reinforcing portions10,11and11protruding backward are respectively provided at the areas where the second reinforcing portions7,9and9are provided. The third reinforcing portions10,11and11are formed so that portions extending vertically and portions extending horizontally cross each other, which are positioned between the through holes3a,3a, . . . or under the through holes3a,3a, . . . .

The first reinforcing portion6, the second reinforcing portions7,8,9,9and the third reinforcing portions10,11,11are formed by, for example, drawing processing.

It is possible to reduce a thickness and to secure high rigidity while maintaining a simple structure of the back chassis3by forming the first reinforcing portion6, the second reinforcing portions7,8,9,9and the third reinforcing portions10,11,11by the drawing processing.

The display4is, for example, a liquid crystal display, which is formed in a landscape rectangular shape having approximately the same size as the back chassis3(refer toFIG. 3andFIG. 4). The display4has a display surface4aas a front surface, including a pair of transparent plates arranged in the front and back, polarization films and so on.

The display4is arranged on the front side of the back chassis3, in which various components for displaying images such as transparent electrodes, liquid crystal, alignment films and color filters are arranged.

The rear cover5is formed to have a landscape rectangular shape having approximately the same size as the back chassis3(refer toFIG. 7andFIG. 8) so as to have a thickness of, for example, approximately 1 mm by vacuum forming.

The rear cover5can be formed to be thin by forming the rear cover5by the vacuum forming, which reduces the thickness of the display apparatus1.

The rear cover5is made of, for example, polystyrene (PS), a mixed material of polystyrene and polyphenyleneether (PPE), a copolymer of polycarbonate/Acrylonitrile Butadiene Styrene (ABS) and so on.

A portion in a lower end side of the rear cover5is formed as a protruding portion5aprotruding backward as compared with other portions.

In an outer peripheral portion other than the lower end portion in the rear cover5, first screw insertion holes5b,5b, . . . are formed at intervals in a circumferential direction. The first screw insertion holes5b,5b, . . . are formed in a long-hole shape extending toward a center portion of the rear cover5(refer toFIG. 9).

Second screw insertion holes5c,5c, . . . having a circular shape are formed in portions close to the center of the rear cover5.

Insertion notches5d,5d, . . . opening downward are formed at the lower end portion of the rear cover5apart from one another in the right and left directions.

The rear cover5is disposed in a state of touching a back surface of the back chassis3. As the rear cover5is disposed in the state of touching the back surface of the back chassis3, the leakage of light from the through holes3a,3a, . . . formed in the back chassis3can be prevented by the rear cover5.

A frame12is attached to outer peripheral portions of the back chassis3and the display4(refer toFIG. 1toFIG. 4).

The frame12is formed by, for example, connecting an upper frame portion13extending in the right and left directions, side frame portions14,14extending in upper and lower directions and a lower frame portion15extending in the right and left directions in a frame shape (refer toFIG. 10toFIG. 12). The upper frame portion13, the side frame portions14,14and the lower frame portion15are made of, for example, aluminum.

The upper frame portion13includes a coupling surface portion13afacing the upper and lower directions, a first presser-surface portion13bprotruding downward from a front edge of the coupling surface portion13a, a second presser-surface portion13cprotruding downward from a rear edge of the coupling surface portion13aand a holding surface portion13dprotruding obliquely downward from the rear edge of the coupling surface portion13a, which are integrally formed as shown inFIG. 13.

The side frame portion14includes a coupling surface portion14afacing the right and left directions, a first presser-surface portion14bprotruding from a front edge of the coupling surface portion14atoalateral direction (inward), a second presser-surface portion14cprotruding from a rear edge of the coupling surface portion14ato the lateral direction (inward) and a holding surface portion14dprotruding from the rear edge of the coupling surface portion14ato an oblique lateral direction, which are integrally formed.

The lower frame portion15includes a coupling surface portion15afacing the upper and lower directions, a first presser-surface portion15bprotruding upward from a front edge of the coupling surface portion15a, a second presser-surface portion15cprotruding upward from an intermediate portion of the coupling surface portion15ain the front and back direction and a connecting surface portion15dprotruding upward from a rear edge of the coupling surface portion15a, which are integrally formed as shown inFIG. 14.

Engaging holes15e,15e, . . . extending in the right and left directions are formed in the connecting surface portion15dof the lower frame portion15apart from one another in the right and left directions.

The outer peripheral portions of the back chassis3and the display4are inserted between the first presser-surface portion13band the second presser-surface portion13cof the upper frame portion13, between the first presser-surface portions14b,14band the second presser-surface portions14c,14cof the side frame portions14,14and between the first presser-surface portion15band the second presser-surface portion15cof the lower frame portion15to be held by the frame12(refer toFIG. 12).

As described above, the outer peripheral portion of the back chassis3and the outer peripheral portion of the display4are held by the frame12which is formed in a C-shape in cross section by the coupling surface portions13a,14a,14aand15a, the first presser-surface portion13b,14b,14band15b/and the second presser-surface portion13c,14c,14cand15c.

Therefore, the frame12increases the strength of the outer peripheral portion of the display apparatus1, which improves the rigidity of the display apparatus1.

In a state where the back chassis3and the display4are held by the frame12, both end portions in right and left of the second presser-surface portion13cof the upper frame portion13and upper end portions of the second presser-surface portions14c,14cof the side frame portions14,14are respectively connected by screw clamping and so on through, for example, L-shaped connecting plates16,16(refer toFIG. 15). Lower end portions of the second presser-surface portions14c,14cof the side frame portions14,14and both end portions in right and left of the second presser-surface portions15c,15cof the lower end portions15,15are respectively connected by screw clamping and so on (refer toFIG. 16).

In the state where the back chassis3and the display4are held by the frame12, the lower end portion of the back chassis3and connecting surface portion15dof the lower frame portions15,15are connected by, for example, screw clamping and so on through reinforcing plates17,17.

The reinforcing plates17,17are formed in a shape extending in right and left directions apart from each other in right and left directions.

In the outer peripheral portion of the rear cover5, an upper end portion is inserted between the second presser-surface portion13cand the holding surface portion13dof the upper frame portion13to be held, and both end portions in right and left are respectively inserted between the second presser-surface portions14c,14cand the holding surface portions14d,14dof the side frame portions14,14to be held (refer toFIG. 17).

As the holding surface portion13d,14dand14dholding the outer peripheral portion of the rear cover5are respectively provided in the upper frame portion13and the side frame portions14,14in the frame12as described above, it is possible to prevent the rear cover5from bending even when the rear cover5is formed to be thin, therefore, the thickness of the display apparatus1can be reduced while preventing the bending of the rear cover5.

When the rear cover5is formed by vacuum forming, an outer peripheral surface of the rear cover5is formed as a fracture surface for performing cutting by press working for forming an outer shape.

However, the outer peripheral portion of the rear cover5is inserted between the second presser-surface portions13c,14c,14cand the holding surface portions13d,14d,14d, thereby closing the outer peripheral portion of the rear cover5by the upper frame portion13and the side frame portions14,14and concealing the fracture surface of the rear cover5.

Stepped screws100,100, . . . are inserted into the screw insertion holes5b,5b, . . . formed at the outer peripheral portion other than the lower end portion in the rear cover5and the second screw insertion holes5c,5c, . . . formed in the center portion of the rear cover5to be screwed into the back chassis3or the frame12, as a result, the rear cover5is pressed against the back chassis3(refer toFIG. 18).

At this time, a stepped portion103provided between a head portion101and a screw portion102of the stepped screw100is inserted into the first insertion hole5b. As described above, the screw insertion holes5b,5b, . . . are formed in the long hole shape extending toward the center portion of the rear cover5, therefore, the rear cover5is displaced (moved) with respect to the stepped screw100even when slight expansion and contraction occur in the rear cover5after forming. Accordingly, the rear cover5is pressed against the back chassis3in a good condition without occurrence of distortion and deformation in the rear cover5.

The stepped portion103of the stepped screw100is also inserted into the second screw insertion hole5c. The size of the second screw insertion hole5cis formed to be larger than the stepped portion103, therefore, the rear cover5is displaced (moved) with respect to the stepped screw100even when slight expansion and contraction occur in the rear cover5after forming. Accordingly, the rear cover5is pressed against the back chassis3in a good condition without occurrence of distortion and deformation in the rear cover5.

An arrangement case18is attached on a back surface side in the lower end portion of the rear cover5. The arrangement case18is made of a resin material, including a substrate arrangement portion19and speaker arrangement portions20,20provided so as to protrude in lateral directions respectively from a lower half portion of the substrate arrangement portion19(refer toFIG. 19andFIG. 20.

In the substrate arrangement portion19, not-shown plural circuit substrates, attachment members 21, 21, . . . to which these circuit substrates are attached and so on are housed and arranged.

As the circuit substrates, for example, a circuit substrate for driving a light source which drives the light source (light emitting diode) functioning as a backlight, a circuit substrate for outputting images which outputs images to the display4, a circuit substrate for control which performs drive control of the display4and other circuit substrates are provided. These circuit substrates are connected to a not-shown drive circuit portion and so on respectively arranged at the lower end portion of the display4by a not-shown wiring plate such as a flexible printed wiring plate.

These circuit substrates are arranged in a state of facing, for example, the front and back directions. Accordingly, the thickness of the arrangement case18in the front and back directions can be reduced, which reduces the thickness of the display apparatus1.

Connectors19a,19a, . . . are provided on a side surface of the substrate arrangement portion19. The connectors19a,19a, . . . are connected to the above circuit substrates, and various types of cables are connected to the connectors19a,19a, . . . from the outside. Louvers19b,19b, . . . are formed on an upper surface of the substrate arrangement portion19and air intake vents19c,19c, . . . are formed in a position below the louvers19b,19b, . . . .

At the time of driving the circuit substrates and so on, cooling air is taken into the substrate arrangement portion19from the air intake vents19c,19c, . . . , and the temperature of the taken cooling air is increased and the air is discharged outside from the louvers19b,19b, . . . . Therefore, the temperature increase inside the substrate arrangement portion19at the time of driving the circuit substrates can be suppressed.

In the speaker arrangement portions20,20, speaker units22,22are respectively housed and arranged. On a lower surface of the speaker arrangement portions20,20, sound releasing holes20a,20a, . . . are respectively formed. Sound outputted from the speaker units22,22is outputted from the sound releasing holes20a,20a, . . . respectively.

Concave portions for arrangement18a,18aare formed at positions of both ends in right and left of the substrate arrangement19in the arrangement case18. The concave portions for arrangement18a,18aopen forward and downward.

An attachment portion18bprotruding downward is provided at a center portion of a lower end portion of the arrangement case18in the right and left directions.

In the lower end portion of the arrangement case18, engagement pieces18d,18c, . . . are provided apart from one another in the right and left directions. The engagement pieces18d,18c, . . . protrude forward, which are formed to have an L-shape in cross section.

The arrangement case18is attached to the lower end portion in the back surface of the rear cover5by screw clamping and so on in a state where the engagement pieces18d,18c, . . . are respectively inserted into the engaging holes15e,15e, . . . formed in the connecting surface portion15dof the lower frame portion15and engaged. At this time, the engagement pieces18d,18c, . . . are respectively inserted into the insertion notches5d,5d, . . . of the rear cover5.

The attachment of the arrangement case18is performed by, for example, a not-shown attachment screw inserted into a screw insertion hole of the arrangement case18being inserted into part of the rear cover5and being screwed into the back chassis3.

In the state where the arrangement case18is attached, part of the lower end portion of the rear cover5is held from a backward direction by the arrangement case18. Accordingly, curvature and deformation in the lower end portion of the rear cover5can be prevented. Moreover, it is not necessary to press the part of the lower end portion of the rear cover5against the back chassis3by screw clamping and the like, which improves workability in assembly work of the display apparatus1.

In the state where the arrangement case18is attached as described above, the attachment portion18bis positioned in a state of protruding below the back chassis3, and a communication box23is attached to the attachment portion18b(refer toFIG. 1). A not-shown substrate for wireless communication is arranged in the communication box23, which enables, for example, transmission/reception of signals between a not-shown remote control device and the display apparatus1.

As described above, the arrangement case18is attached in a position opposite to a surface of the back chassis3which faces the display4in the display apparatus1, and the plural circuit substrates are housed in the arrangement case18, therefore, portions to which the arrangement case18is not attached in the display apparatus1can be reduced in thickness.

Additionally, it is not necessary to provide a case in which the circuit substrates are arranged and a case in which the speaker units22,22are arranged separately as the speaker units22,22are housed in the arrangement case18in addition to the circuit substrates. Therefore, the size of the display apparatus1can be reduced by using arrangement space efficiently. The size reduction is realized also by cutting the number of components, which can reduce manufacturing costs.

Furthermore, portions to which the arrangement case is not attached in the display apparatus1can be also reduced in thickness as the speaker units22,22are housed in the arrangement case18.

Moreover, as the arrangement case18is attached to the lower end portion of the back chassis3, the center of gravity in the entire display apparatus1is positioned on a lower side, therefore, it is possible to secure a stable setting state of the display apparatus1and to prevent the display apparatus1from falling down due to the disturbance such as vibrations.

A stand24is provided on a lower surface of the arrangement case18(refer toFIG. 1toFIG. 4). The stand24includes a base portion25placed on a mounting surface such as a desk, supporting surface portions26,26fixed on the base portion25at one end portions respectively and connecting protrusions27,27respectively attached to the other end portions of the supporting surface portions26,26.

The base portion25is formed in a bar shape folded in a given shape, a cross-sectional shape of which is, for example, a polygon such as a hexagon. The base portion25includes a mounting portion25aextending in the right and left directions, intermediate portions25b,25brespectively protruding obliquely upward in the back direction from both end portions in right and left of the mounting portion25aand connecting portions25c,25cprotruding obliquely downward in the back direction from rear ends of the intermediate portions25b,25b. Portions where the mounting portion25ais connected to the intermediate portions25b,25bin the base portion25are provided as receiving portions28,28.

The supporting surface portions26,26are formed in a landscape-plate shape facing approximately in the upper and lower directions, outer end portions of which are respectively fixed to front end portions of the connecting portions25c,25c.

As the supporting surface portions26,26are respectively fixed to the connecting portions25c,25cas described above, flat portions are formed in the connecting portions25c,25cby forming the cross-sectional shape of the base portion25to be a polygon such as a hexagon, therefore, a sufficient contact area of the supporting surface portions26,26with respect to the connecting portions25c,25ccan be secured. Accordingly, a stable fixing state of the supporting surface portions26,26with respect to the connecting portions25c,25ccan be obtained.

The cross-sectional shape of the base portion25is not limited to the polygon, and may be formed to be other shapes such as a circular shape, an elliptical shape and an oval shape.

The stand24is connected by screw clamping and so on in a state where the connecting protrusions27,27are respectively inserted into the concave portions for arrangement18a,18aof the arrangement case18from below. In the state where the stand24is connected, inner end portions of the supporting surface portions26,26touch the lower surface of the arrangement case18and the apparatus body2is held by the stand24.

As the stand24is in a state where the mounting portion25aand rear end portions of the connecting portions25c,25ctouch the mounting surface such as the desk, the apparatus body2is placed on the desk through the stand24. At this time, the receiving portions28,28of the stand24are positioned just below the frame12, and lower frame portion15touches the receiving portions28,28, therefore, loads of the display4, the rear cover5and the frame12are received by the receiving portions28,28(refer toFIG. 22).

Accordingly, it is possible to place the display apparatus1on the mounting surface such as a desk in the stable state, which can secure the stable setting state of the display apparatus1.

[Use Example of Stand]

Another use example of the stand24will be explained below (refer toFIG. 23andFIG. 24).

The example in which the stand24is used at the time of setting the apparatus on the mounting surface such as a desk has been shown as the above, however, it is also possible to use the stand24as an attachment member for wall hanging as described below.

When the stand24is used as the attachment member for wall hanging, the stand24is used by removing the connecting protrusions27,27from the supporting surface portions26,26. The supporting surface portions26,26of the stand24are attached to a back surface of the apparatus body2by, for example, screw clamping and so on in a state where the mounting portion25aof the base portion25is positioned on the highest position.

In the state where the stand24is attached to the back surface of the apparatus body2, the mounting portion25aof the stand24is located at a position more backward than a rear surface of the arrangement case18.

A bracket200is attached to a wall surface1000, and the mounting portion25aof the stand24is attached to the bracket200, thereby allowing the display apparatus1to be in the wall hanging state. At this time, the mounting portion25aof the stand24is located at the position more backward than the rear surface of the arrangement case18, therefore, the arrangement case18does not interfere with the wall surface1000and a good wall hanging state of the display apparatus1can be secured.

As described above, the stand24is attached to the lower end portion of the apparatus body2to have a function of standing the apparatus body2, and is also attached to the back surface of the apparatus body2to have a function of setting the apparatus body2so as to abut on the wall surface1000.

Accordingly, it is possible to set the apparatus body2in a desired state by changing the position of attaching the stand24with respect to the apparatus body2, which can improve usability.
