As shown in
The display panel 10 may include a self-emissive display element or a non-emissive display element.
The self-emissive display device may visually output an image by emitting light on its own without a separate light source 62. For example, a light emitting diode (LED), an organic light emitting diode (OLED), or a quantum dot-organic light emitting diode (QD-OLED), a micro LED made of an inorganic light emitting material, and the like may be a device capable of emitting light on its own based on a supplied current.
The non-emissive display device may include a non-emissive display device that requires a separate light source 62. For example, a liquid crystal display (LCD), which is a non-emissive display device, changes the arrangement of liquid crystals by an electric current, but requires the separate light source 62 to visually output an image through the changed arrangement of liquid crystals.
The display device 1 of the present disclosure may be applied to both the display panel 10 having a self-emissive display element and the display panel 10 having a non-emissive display element. However, for ease of description, the display panel 10 including the non-emissive display element will be assumed and described.
The display panel 10 may require a stand 90 for stable installation. In the description, it is assumed that the stand 90 includes a surface on a lower side of the display panel 10 that supports a load of the display panel 10 to prevent the display panel 10 from tipping over. However, the present disclosure is not limited thereto, and the stand 90 may include supporting the display panel 10 from a rear side of the display panel 10 by securing the display panel 10 to a wall.
The stand 90 may be coupled to a rear chassis 100 (see
For ease of description, it is assumed that the stand 90 is provided in a single position corresponding to the center of the display panel 10. However, the present disclosure is not limited thereto, and the ideas implemented in the present disclosure may also be applied to the display device 1 in which the stands 90 are arranged symmetrically on the left and right with respect to the center of the display panel 10 or including a plurality of stands 90.
Hereinafter, it will be described what further configurations the display device 1 may include.
As shown in
The display panel 10 may include a liquid crystal panel formed by encapsulating liquid crystal between two glass substrates 61, each provided with electrodes, and may display an image facing forward.
The display panel 10 may have a rectangular shape.
The chassis assembly may include a front chassis 20, a middle chassis 30, and the rear chassis 100.
The front chassis 20 extending along a border of the display panel 10 may be arranged to protect the up, down, left, and right directions of the display panel 10.
The front chassis 20 may include a bezel portion covering a front outer side of the display panel 10, and a side portion bent rearwardly from an end of the bezel portion to cover a side surface of the middle chassis 30.
The front chassis 20 may be coupled to a front side of the middle chassis 30 to be held in a state in which the display panel 10 is installed on the middle chassis 30.
The middle chassis 30 may be arranged with the display panel 10 and the front chassis 20 sequentially on the front side, and the rear chassis 100 on the rear side to support each configuration, as well as to maintain the display panel 10 and the rear chassis 100 spaced apart from each other.
The rear chassis 100 may be coupled within the middle chassis 30.
The rear chassis 100 may be formed in the shape of a high strength multifaceted plate and may include a metallic material (e.g., aluminum or aluminum alloy, etc.) that is less susceptible to thermal deformation due to heat generated by the heat of a light source module 60 and/or the display panel 10 received in the rear chassis 100.
The rear chassis 100 may include a material having high thermal conductivity. Accordingly, the heat generated by the light source module 60 may be easily dissipated to improve the reliability of the display device 1.
The rear chassis 100 may be formed from a plastic material (e.g., polycarbonate (PC) material) or by adding glass fiber to a plastic material.
However, in contrast to the present embodiment, at least one of the front chassis 20 and the middle chassis 30 may be omitted or may formed integrally with each other.
The display device 1 may further include a housing enclosing the chassis assembly to protect and accommodate such chassis assembly, or the rear cover 500 covering a rear side of the rear chassis 100.
The display device 1 may include a frame chassis 200 coupled to a front side of the rear cover 500 to couple the rear cover 500 to the rear chassis 100. This will be described in detail later with reference to the associated drawings.
An electrical components 70 that enables the display device 1 to perform various functions may be disposed on an inner side of the rear cover 500. The electrical components 70 may be provided in a plurality. For the plurality of electrical components 70, each electrical components 70 may be connected by a cable 71 to enable the electrical components to interact with each other.
The display device 1 may further include the BLU arranged to supply light to the display panel 10.
The light source module 60 may include the light source 62 that emits light.
The BLU may be of a direct type in which the light source 62 is disposed directly below the display panel 10, as in the present embodiment. The BLU may include the light source module 60 comprising the light source 62 and the substrate 61 on which the light source 62 is mounted, and various optical sheets 40 disposed in a travel path of the light emitted from the light source module 60.
The light source 62 may be provided as an LED package accommodating LEDs that emit light. The light source module 60 may be arranged to supply light to the display panel 10. The light source module 60 may supply light to the display panel 10 from the rear side of the display panel 10. The light source module 60 may be disposed at the rear side of the display panel 10.
In contrast to a conventional LED, the light source 62 of the light source module 60 may be provided as a mini-LED, which is formed from LED chips having a size of 100 to 300 μm.
Alternatively, a cold cathode fluorescent lamp (CCFL) or an external electrode fluorescent lamp (EEFL) may be used as the light source 62 in the present embodiment.
A plurality of light sources 62 may be mounted on the substrate 61 at given intervals. The plurality of light sources 62 may all be formed in the same configuration, and the single light source 62 of the plurality of light sources 62 will be described below.
Printed circuit wiring for transmitting driving power and signals to the light source 62 may be formed on the substrate 61.
In contrast to the edge-type display device 1, the light emitted from the light source module 60 may directly supply light to the display panel 10. In this case, to improve the characteristics of the light emitted from the light source module 60, the optical sheet 40 may be disposed between the light source module 60 and the display panel 10.
The optical sheet 40 may include a prism sheet and a protection sheet.
The prism sheet may include a prism pattern in the shape of a triangular prism, wherein the prism pattern may be arranged in a plurality of adjacent ones to form a plurality of strips. Such prism patterns may be formed by protruding toward the display panel 10 in rows in a repeating pattern of peaks and troughs. Light diffused from the light source module 60 may be refracted while passing through the prism patterns, and thus light may be incident on the display panel 10 in a vertical direction.
The protection sheet may be designed to protect various components from external impact or entry of foreign substances, and in particular, the prism sheet may be susceptible to scratches, and thus the protection sheet may prevent the prism sheet from being scratched.
The display device 1 may include a light conversion member 50 arranged to change the wavelength of the light emitted from the light source module 60.
The light conversion member 50 may be disposed between the display panel 10 and the light source module 60. As the light emitted from the light source module 60 passes through the light conversion member 50, the wavelength of the transmitted light may be changed and the changed light may be introduced into the display panel 10.
The light source module 60 may emit light in the blue color range. In this case, the light in the blue color range may be partially biased toward green. The blue-colored light generated by the light source module 60 may be converted to white light by the light conversion member 50.
The light conversion member 50 may include a quantum dot (QD).
The light conversion member 50 may convert the color of the incident light emitted from the light source module 60 and emit light of different colors. For example, the light conversion member 50 may convert the incident blue-colored light emitted from the light source module 60 into red light and green light (or yellow light) by different QDs, and then emit the converted light to the outside. In particular, the light conversion member 50 may emit light of a different color from the incident light by changing the wavelength of the incident light (wavelength shift).
The QDs may emit light of a specific wavelength by emitting themselves or by absorbing light when a voltage is applied.
The electrons in the QDs are located in a low energy level (or band) in a stable state. When the QDs absorb light from the outside, the electrons in the low energy level move to a high energy level (or band). Since the electrons in the high energy levels are in an unstable state, the electrons may naturally move from the high energy level to the low energy level. Accordingly, during the transition from the high energy level to the low energy level, the electrons may emit light equal to the energy difference between the high energy level and the low energy level.
The wavelength of the emitted light may be determined by the energy difference between the high energy level and the low energy level.
In particular, the smaller the QD, the shorter the wavelength of light it may emit, and the larger the QD, the longer the wavelength of light it may emit. For example, a QD with a diameter of 2 nanometers [nm] may emit blue-colored light, while a QD with a diameter of about 10 nanometers [nm] may emit red-colored light.
Furthermore, by using the QDs of different sizes, the QDs may be made to emit different wavelengths of light, from red-colored light to blue-colored light. In other words, by using of different sizes of the QDs, it is possible to generate light with natural colors.
The light conversion member 50 may be manufactured by dispersing the QDs described above in a resin. When light is incident on the light conversion member 50 from the light source module 60, the incident light may excite the electrons of the QDs included in the light conversion member 50. In other words, the electrons in the low energy level (or band) may be moved to the high energy level (or band) by the incident light.
Then, as the excited electrons move from the high energy level to the low energy level, the QDs may emit light of different wavelengths depending on their size. The light of different wavelengths may then pass through the display panel 10 to generate an image. Accordingly, when blue-colored light emitted from the light source module 60 is incident on the light conversion member 50, light in the green color range and light in the red color range may be emitted by the green-colored light QDs and the red-colored light QDs.
Finally, white-colored light, which is a mixture of light having three different wavelengths, may be incident on the display panel 10 by the blue-colored light emitted from the light source module 60 and the green-colored light and the red-colored light emitted from the light conversion member 50.
Hereinafter, the rear chassis 100 and a configuration behind the rear chassis 100 will be described in more detail.
As shown in
The display device 1 may have a thin thickness in order to provide high aesthetics to a user. The thinner the display device 1 is, the more beautiful the display device 1 may be perceived by the user.
To this end, the thickness of the rear cover 500 of the display device 1 may be reduced.
The rear cover 500 may have a shape corresponding to the rear chassis 100 and cover the entire rear of the rear chassis 100. At the rear side of the rear chassis 100, the plurality of electrical components 70 may be arranged throughout the rear side of the rear chassis 100. Accordingly, since the rear cover 500 covers the rear side of the rear chassis 100 as a whole, any electrical components 70 that may be sporadically located at the rear side of the rear chassis 100 may be covered by the rear cover 500.
The rear cover 500 may include a plastic material to lighten the weight of the display device 1. If the rear cover 500 is made of a plastic material, machining costs and material costs may be reduced.
Typically, the rear cover 500 may be produced by a plastic injection process.
When the thickness of the rear cover 500 is 1 mm or less, it may be difficult to produce the rear cover by an injection process for process reasons. In this case, the rear cover 500 may be produced by a rolling press method.
The rear cover 500 produced by such a method may have a constant thickness. In other words, the rear cover 500 may have a plate shape.
The rear cover 500 may be coupled to the rear chassis 100. The rear cover 500 may be attached to the rear chassis 100 by an adhesive.
In particular, the rear cover 500 may be detachably coupled to the rear chassis 100 to allow easy repair of the electrical components 70 located between the rear chassis 100 and the rear cover 500. When the rear cover 500 is attached to the rear chassis 100 by an adhesive, it is preferable to use an adhesive that detachably attaches the rear chassis 100 and the rear cover 500.
In the event that the rear chassis 100 and the rear cover 500 are not attached by an adhesive, the frame chassis 200 may be provided to detachably couple the rear cover 500 to the rear chassis 100.
The frame chassis 200 may be attached to the rear cover 500 on one side and detachably arranged to the rear chassis 100 on the other side. The frame chassis 200 may be manufactured by injection molding so that the frame chassis 200 may have a certain shape in order to be detachably coupled to the rear chassis 100.
A configuration for the frame chassis 200 to be detachably coupled to the rear chassis 100 will be described in more detail with reference to
The rear chassis 100 may support the display panel 10. The rear chassis 100 may be formed in the shape of a rectangular thin plate. The rear chassis 100 may include a rear chassis body 101. To increase the strength of the rear chassis 100, the rear chassis body 101 of the rear chassis 100 may include reinforcing ribs 110 protruding rearwardly.
The reinforcing ribs 110 may include frame ribs 111 located at the center of the rear chassis 100 and extending in the vertical direction. The reinforcing ribs 110 may include edge ribs 112 extending along an edge of the rear chassis 100. The reinforcing ribs 110 may include side ribs 113 between the frame rib 111 and the edge rib 112.
The side ribs 113 may be provided in a plurality. A seating space 114 may be provided between the plurality of side ribs 113, the seating space 114 being recessed toward the front. In the seating space 114, the cable 71 connecting the electrical components 70 may be seated thereon. This is because the cable 71 seated on the side ribs 113 may cause the thickness of the display device 1 to increase.
The frame chassis 200 may include a center frame chassis 210 located corresponding to a center of the rear cover 500. The center frame chassis 210 may be located at a position corresponding to the reinforcing ribs 110. Accordingly, the center frame chassis 210 may be formed to correspond to the frame ribs 111.
In other words, the center frame chassis 210 may be detachably coupled to the frame ribs 111.
The frame chassis 200 may include an edge frame chassis 220 attached to an edge of the rear cover 500. The edge frame chassis 220 may be detachably coupled to the front chassis 20 (see
The edge frame chassis 220 may be positioned corresponding to the rear side of the rear chassis 100, where the reinforcing ribs 110 are not formed, to prevent the thickness of the display device 1 from increasing. The edge ribs 112 may be formed to be spaced inwardly from an outline of the edge of the rear chassis 100. In this case, the edge frame chassis 220 may be formed at a position corresponding to the rear chassis body 101 formed on an outer side of the edge ribs 112.
The plurality of electrical components 70 may be disposed between the rear chassis 100 and the rear cover 500. The cables 71 may be provided to connect each of the electrical components 70. The cables 71 may be located between the frame chassis 200 and the rear chassis 100.
In summary, the plurality of electrical components 70 and the cables 71 connecting the plurality of electrical components 70 may be located at the rear side of the rear chassis 100. The rear cover 500 may be located on the rear side of the plurality of electrical components 70 and the cable 71 connecting the plurality of electrical components 70. The rear cover 500 may have a shape of a plate, so that in order for the rear cover 500 to be coupled to the rear side of the rear chassis 100, the frame chassis 200 couplable to the front side of the rear cover 500 may be provided. The frame chassis 200 may allow the rear cover 500 to be detachably coupled to the rear chassis 100.
Hereinafter, a manner in which the frame chassis 200 is detachably coupled to the rear chassis 100 will be described.
As shown in
Of the frame chassis 200, the center frame chassis 210 is shown in
The rear chassis 100 may include a wire 120. The frame chassis 200 may include a wire hook 351 at a position corresponding to the wire 120. The frame chassis 200 may be coupled to the rear chassis 100 by the wire hook 351 being hooked to the wire 120. In addition, by appropriately adjusting the shape of the wire hook 351, the wire hook 351 may be released from the wire 120 when the user applies an appropriate force. Accordingly, the frame chassis 200 may be releasably coupled to the rear chassis 100.
In addition, a wire coupling hole 121 may be formed on a rear side of the wire 120 to allow the wire hook 351 to be more easily coupled to the wire 120.
The wire hook 351 may be coupled to the wire 120 only when the wire hook 351 contacts the wire 120 at a precise position. A member may be needed to guide the position of the frame chassis 200 so that the wire hook 351 is positioned at the target position.
To this end, the frame chassis 200 may include a guide boss 352 protruding toward the rear chassis 100. The rear chassis 100 may include a boss hole 122 at a position corresponding to the guide boss 352. The guide boss 352 may be inserted into the boss hole 122. As a result, the position of the frame chassis 200 may be guided.
The guide boss 352 may have a hollow cylindrical shape. This may reduce the manufacturing cost of the guide boss 352.
The frame chassis 200 may include a guide protrusion 353 protruding toward the rear chassis 100. The rear chassis 100 may include a protrusion hole 123 at a position corresponding to the guide protrusion 353. The guide protrusion 353 may be inserted into the protrusion hole 123. As a result, the position of the frame chassis 200 may be guided.
The guide protrusion 353 may have a solid cylindrical shape. The guide protrusion 353 may have a cross-section that is not radially symmetrical. Accordingly, when the frame chassis 200 is coupled to the rear chassis 100, rotational movement of the frame chassis 200 may be prevented.
In the case where the frame chassis 200 includes both the guide boss 352 and the guide protrusion 353, the position of the frame chassis 200 may be guided to a desired position and direction.
The rear chassis 100 may be provided with a wall mounting hole 124 for mounting the display device 1 to a wall. A fastener, such as a screw, may be fastened to the wall mounting hole 124. A mounting guide 354 protruding toward the rear chassis 100 may be provided at a position corresponding to the wall mounting hole 124 to prevent deformation of the frame chassis 200.
The frame chassis 200 may be attached to the rear cover 500 by an adhesive 600. Accordingly, in the case where the frame chassis 200 is detachably coupled to the rear chassis 100 in the manner described above, the rear cover 500 may also be detachably coupled to the rear chassis 100.
However, in the event that the rear cover 500 and the frame chassis 200 are coupled by the adhesive 600, the rear cover 500 may be subject to deformation.
Further description thereof will follow.
As shown in
In this case, the adhesive 600 may be an adhesive in the form of an applicator or double-sided tape. The adhesive 600 may be anything that attaches the frame chassis 200 and the rear cover 500.
The frame chassis 200 may include the center frame chassis 210 attached to the center of the rear cover 500. The center frame chassis 210 may be arranged to be elongated in the vertical direction. The center frame chassis 210 may include a pair of center frame chassis 210 arranged side by side on the left and right so that the rear cover 500 may be stably coupled to the rear chassis 100.
The frame chassis 200 may include the edge frame chassis 220 attached to the rear cover 500 corresponding to the edge of the rear cover 500. The rear cover 500 may have a rectangular shape with an elongated width. The edge frame chassis 220 may include a long side frame chassis 221 corresponding to a relatively long transverse side of the rear cover 500. The edge frame chassis 220 may include a short side frame chassis 222 corresponding to a relatively short longitudinal side of the rear cover 500. The long side frame chassis 221 may be provided one on each of up and down, and the short side frame chassis 222 may be provided one on each of left and right. As a result, the edge frame chassis 220 may be arranged to correspond to the edge of the rear cover 500.
The side frame chassis 230 may be disposed between the center frame chassis 210 and the edge frame chassis 220. The shape of the side frame chassis 230 is shown to be a rectangular shape in the present disclosure, but may also be formed in an L-shaped. The side frame chassis 230 may assist in coupling the rear cover 500 to the rear chassis 100 between the edge frame chassis 220 and the center frame chassis 210, which may help to more securely couple the rear cover 500 to the rear chassis 100. The center frame chassis 210 may be arranged to extend in the vertical direction, so that the side frame chassis 230 may be positioned between the center frame chassis 210 and the short side frame chassis 222. As the center frame chassis 210 may be formed in pairs, a pair of side frame chassis 230 may be positioned between each of the center frame chassis 210 and the edge frame chassis 220.
The frame chassis 200 may include a through space 410 or a through hole 350 formed by penetrating in a front-to-back direction. The through space 410 or through hole 350 may be formed for the cables 71 or the electrical components 70 to be located in a corresponding region. Alternatively, the through space 410 or the through hole 350 may be formed to use less material to reduce the unit cost of the frame chassis 200. The arrangement of the cables 71 corresponding to the through space 410 will be described below with reference to the associated drawings.
In the event that the adhesive 600 is used in the process of coupling the frame chassis 200 to the rear cover 500, the adhesive 600 may harden in the process of coupling the frame chassis 200 and the rear cover 500. The hardened adhesive 600 may be subject to shrinkage, which may cause deformation of the frame chassis 200 to which the adhesive 600 is attached. Furthermore, deformation of the frame chassis 200 may cause deformation of the rear cover 500 to which the frame chassis 200 is attached by the adhesive 600.
In this case, since the through space 410 or the through hole 350 may be formed in the frame chassis 200, deformation may occur around the through space 410 or the through hole 350. When the frame chassis 200 is deformed in the front-to-back direction, the deformation of the frame chassis 200 may cause the rear side of the rear cover 500 to protrude. This may reduce the aesthetics of the display device 1.
To avoid such a situation, the through space 410 of the frame chassis 200 may be formed to extend toward an end of the frame chassis 200.
For example, the frame chassis 200 may include a first frame 310 extending in a first direction to be attached to the rear cover 500 and including a first free end 311 in the first direction, and a second frame 320 extending in a second direction to be attached to the rear cover 500 and including a second free end 321 in the second direction, corresponding to the first frame 310. To prevent deformation of the rear cover 500, the second free end 321 of the second frame 320 may be separated and spaced apart from the first free end 311.
Here, the first free end 311 and the second free end 321 may refer to relatively movable ends of the first frame 310 and the second frame 320. However, this is not necessarily limited to referring to the ends that are not coupled to any configuration and thus have a degree of freedom.
In other words, the first free end 311 and the second free end 321 may be referred to as corresponding configurations.
Furthermore, the first direction and the second direction may be different directions, but may also be the same direction. Preferably, the first direction and the second direction may refer to the same direction. The first direction and the second direction may both point upward.
Accordingly, the first frame 310 and the second frame 320 may include a shape extending in the vertical direction.
Additionally, the first frame 310 and the second frame 320 may have a shape having the same length.
However, since the wire hook 351 and/or the guide boss 352 may be formed on the first frame 310, the first frame 310 may have a different shape from the second frame 320.
Therefore, a deformation opening 400 may be formed between the first free end 311 and the second free end 321, and the through space 410 may be formed between the first frame 310 and the second frame 320, wherein the through space 410 may extend to the deformation opening 400.
The first frame 310 and the second frame 320 may be arranged in a third direction different from the first and second directions, and the frame chassis 200 may further include a third frame 330 extending in a third direction so as to connect the first frame 310 and the second frame 320.
In the case where the first frame 310 and the second frame 320 are formed separately, the rear cover 500 may not be deformed even without considering deformation in the front-to-back direction. However, when a large number of parts are assembled, the assembly time may be long and the cost may increase as the number of processes increases. Conversely, when manufacturing as a single part, the manufacturing may be completed in a single injection process, and thus speeding up the manufacturing time. Accordingly, it is desirable from a manufacturing point of view to connect the first frame 310 and the second frame 320 by the third frame 330.
In other words, the first frame 310, the second frame 320, and the third frame 330 may be formed to surround at least a portion of the through space 410.
In the case where the frame chassis 200 and the rear cover 500 are coupled by the adhesive 600 and deformation of the frame chassis 200 occurs as the adhesive 600 hardens, the deformation may occur in a left-to-right direction because the first frame 310 and the second frame 310 are separated and spaced apart from each other. Since deformation in the front-to-back direction may be a relatively difficult deformation as it requires deformation of the rear cover 500, the frame chassis 200 may be induced to deform in the left-to-right direction. Accordingly, deformation of the rear chassis 100 may be prevented despite deformation of the frame chassis 200.
In this case, such a feature of the frame chassis 200 may preferably be formed on the center frame chassis 210. For the edge frame chassis 220, the edge frame chassis 220 may be coupled to the front chassis 20 disposed on the edge of the rear chassis 100, so that deformation of the edge frame chassis 220 in the front-to-back direction may be relatively limited. For the side frame chassis 230, the side frame chassis 230 is close to the edge frame chassis 220, so that deformation in the front-to-back direction is relatively difficult to occur. In addition, the side frame chassis 230 does not have a size that allows for much deformation. In particular, when the center frame chassis 210 is coupled to the rear chassis 100, the electrical components 70 may be placed in a corresponding portion. In other words, the center frame chassis 210 may include the through space 410 or the through hole 350, making it relatively easy to deform. Meanwhile, the side frame chassis 230 may not include such through space, making it relatively difficult to be deformed.
Accordingly, the above configurations may be applicable to the frame chassis 200 in general, but may be a necessary configuration for the center frame chassis 210 in particular. In view of this, the present embodiment will be described assuming that the above idea applies only to the center frame chassis 210.
However, as seen above, the frame chassis 200 may have a possibility of being deformed in the front-to-back direction, so it is not necessarily applicable only to the center frame chassis 210, but also to the edge frame chassis 220 and the side frame chassis 230.
The center frame chassis 210 will be described in more detail below.
As shown in
To stably position the first frame 310 and the second frame 320, a connecting frame 340 may be provided to connect the first frame 310 and the second frame 320. The connecting frame 340 may be positioned across the through space 410.
The through space 410 may be divided by the connecting frame 340. A space surrounded by the connecting frame 340, the first frame 310, the second frame 320, and the third frame 330 may be referred to as a closed through space 430. A space surrounded by the connecting frame 340, the first frame 310, and the second frame 320 may be referred to as an open through space 420. In other words, the through space 410 may include the open through space 420 and the closed through space 430.
The guide boss 352 and the guide protrusion 353 mentioned above may be disposed on the third frame 330. In addition, the third frame 330 may include the through hole 350 formed by penetrating the third frame 330 so as to reduce the weight of the frame chassis 200. In addition, the mounting guide 354 may be provided on the third frame 330.
The third frame 330 may not be provided with a separate free end. This is because the third frame 330 is formed on a lower side, where the stand 90 (see
In other words, the display device 1 may include the stand 90 that may be coupled to the rear cover 500 or the rear chassis 100, and the third frame 330 may be positioned adjacent to a location where the stand 90 is coupled.
As shown in
In other words, the first frame 310 and the second frame 320 may be coupled to the rear cover 500 by the adhesive 600, and the third frame 330 may not have the adhesive 600 between the third frame 330 and the rear cover 500. That is, the third frame 330 may not be coupled to the rear cover 500. This may allow the frame chassis 200 to be coupled to the rear cover 500 although less adhesive 600 is used.
However, such an adhesive method may not prevent the third frame 330 from moving in the front-to-back direction, making it even more necessary to prevent the movement in the front-to-back direction as described above.
As shown in
As shown in
The plurality of electrical components 70 may be disposed at the center of an upper side on the left and right sides of a lower side, respectively. The description will be given as an example of the cable 71 connecting the electrical components 70 disposed at the center of the upper side to the electrical components 70 disposed at the left side of the lower side.
The cable 71 may extend from the electrical components 70 disposed at the upper center, through between the center frame chassis 210 and the rear chassis 100, and along the rear side of the frame rib 111, and extend back through between the center frame chassis 210 and the rear chassis 100.
The extended cable 71 may extend through the seating space 114 provided between the side ribs 113 and toward the electrical components 70 disposed on the lower left side. The seating space 114 may provide a space for the cable 71 to pass through without passing over the side rib 113, thereby protecting the cable 71.
More specifically, the cable 71 is shown passing through the through space 410. In other words, it can be seen that the through space 410 may include a first through gap 313 provided for the cable 71 to pass between the first frame 310 and the frame rib 111, and a second through gap 323 provided for the cable 71 to pass between the second frame 320 and the frame rib 111.
As shown in
The cable 71 may extend along a rear surface of the frame rib 111. When the cable 71 is disposed along the rear surface of the frame rib 111, the cable 71 may be disposed through a through gap between the frame rib 111 and the center frame chassis 210.
The first frame 310 may include a first frame support portion 312 formed to correspond to an outer side of the frame rib 111 when the frame chassis 200 is coupled to the rear chassis 100 and protruding toward the rear chassis 100. The second frame 320 may include a second frame support portion 322 formed to correspond to the first frame support portion 312.
In other words, the first frame 310 may include the first frame support portion 312 on a first side spaced apart from the through space 410, which has a greater thickness in the front-to-back direction than a second side adjacent to the through space 410. In other words, the first frame 310 may have a shape whose outer side is thicker than its inner side. This may be also the case for the second frame 320.
As mentioned above, the center frame chassis 210 may be provided with the through space 410 or the through hole 350 in consideration of the electrical components 70 being provided where they are coupled, or as a matter of reducing material costs. Accordingly, a structure such as the wire hook 351, which is coupled to the rear chassis 100, may be formed on an outer side of the center frame chassis 210 or on an outer side of the first frame 310 and the second frame 320. By strongly coupling the rear chassis 100 and the rear cover 500 at the outer sides, the possibility of separation of the rear chassis 100 and the rear cover 500 may be reduced. To this end, the outer side of the center frame chassis 210, i.e., the outer sides of the first frame 310 and the second frame 320 may be provided with the frame support portion having a thick thickness.
Furthermore, the display device 1 may output audio, and thus may include a speaker (not shown) for outputting audio. When a speaker emits sound, vibration is generated. To reduce transmission of such a vibration, a shock absorbing member 80 including a material, such as a non-woven fabric, may be included between the frame chassis 200 and the rear chassis 100. The frame support portions 312 and 322 may be positioned on a rear side of the shock absorbing member 80.
The degree of protrusion of the frame support portions 312 and 322 may be determined by considering the thickness of the shock absorbing member 80 to allow the rear cover 500 to be positioned flat.
In the above, an embodiment of the display device 1 is described in which the through space 410 is formed up to one end of the frame chassis 200 to prevent deformation of the rear cover 500.
Such a frame chassis 200 may be regarded as a type of mounting member. Accordingly, as described above, it is not necessarily to be regarded as a configuration that may be applied only to the display device 1. Given that it is not a configuration that is used only for the display device 1, the ideas represented by the present disclosure may be described as follows.
The mounting member 200 of the present disclosure may be a mounting member that couples a first panel and a second panel positioned facing the first panel, and may include a frame chassis 200 bonded to the first panel by the adhesive 600 and detachably coupled to the second panel to couple the first panel and the second panel. The frame chassis 200 may include the through space 410 formed in a direction facing the first panel, and the through space 410 may extend to an end of the frame chassis 200.
Hereinafter, another embodiment of the display device 1 will be described as an example in which the spirit of the present disclosure is implemented. In the following description, the same configurations as those of the display device 1 above are assigned the same reference numerals, and detailed descriptions may be omitted.
As shown in
If, as in the embodiment mentioned above, a deformation opening 400a is provided between the first free end 311a and the second free end 321a, it may be difficult to attach the frame chassis 200a to the rear cover 500 because the first free end 311a and the second free end 321a are not secured. In this case, the supporter 360a connecting the first free end 311a and the second free end 321a may be formed to restrict the movement of the first free end 311a and the second free end 321a, so that it may be easy to attach the frame chassis 200a to the rear cover 500.
Since the supporter 360a may be removed from the frame chassis 200a after the frame chassis 200a is attached to the rear cover 500, it is preferable to provide the supporter 360a to be easily removable. After the supporter 360a is separated, a first supporter trace portion 361a may be formed at a point where the supporter 360a meets the first free end 311a and a second supporter trace portion 362a may be formed at a point where the supporter 360a meets the second free end 321a.
As shown in
In this case, a third frame 330b may be formed by connecting the third free end 314b and the fourth free end 324b.
The third frame 330b may not include a separate through hole. Accordingly, the first frame 310b and the second frame 320b may be less deformed in the front-to-back direction than in previous embodiments.
As shown in
In this case, a third frame 330c may be formed by connecting the first frame 310c and the second frame 320c. The third frame 330c may be formed across a space between the first frame 310c and the second frame 320c.
Of the space surrounded by the first frame 310c, the second frame 320c, and the third frame 330c, the space on the upper side may be referred to as a first through space 411c, and the space on the lower side may be referred to as a second through space 412c.
As shown in
Because the first frame 310d and the second frame 320d are spaced apart, the frame chassis 200d may be prevented from being deformed in the front-to-back direction.
While the present disclosure has been particularly described with reference to exemplary embodiments, it should be understood by those of skilled in the art that various changes in form and details may be made without departing from the spirit and scope of the present disclosure.
