Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals are used to designate identical or similar elements, and redundant description thereof will be omitted. The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role. In the following description of the embodiments of the present invention, a detailed description of related arts will be omitted when it is determined that the gist of the embodiments disclosed herein may be blurred. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. , ≪ / RTI > equivalents, and alternatives.
Hereinafter, an organic light emitting display (OLED) will be described as an example of the display panel. However, the display panel applicable to the present invention is not limited to the organic display panel, and may be a liquid crystal display Devices, LCDs, plasma display panels (P), and field emission displays (FEDs).
1 to 6 are views showing a configuration of a display device related to the present invention.
Referring to FIG. 1, a body 10 of a display device according to the present invention may include a display panel 100, a module cover 200, and a PCB cover 400.
The display panel 100 is provided on the front surface of the body 10 and images can be displayed. The display panel 100 may output an image by dividing the image into a plurality of pixels, controlling each pixel to emit light in accordance with hue, brightness, and saturation.
The display panel 100 may have a rectangular shape. However, the present invention is not limited thereto, and the display panel 100 may have a shape having a predetermined curvature at an edge. The display panel 100 may be an organic light emitting diode (OLED) panel. However, the present invention is not limited thereto, and the display panel 100 may be a liquid crystal display panel.
The module cover 200 may be provided on the rear surface of the display panel 100. The module cover 200 may be attached directly to the display panel 100. [ The module cover 200 can support the rear surface of the display panel 100. That is, the module cover 200 can reinforce the rigidity of the display panel 100. Accordingly, the module cover 200 may include a lightweight and high-strength material. For example, the module cover 200 may comprise aluminum.
A source PCB 172 may be attached to the lower region of the module cover 200. The module cover 200 may have a hole in an area where the source PCB 172 is positioned to secure an area where the source PCB 172 is to be positioned. If too many holes or holes are formed in the module cover 200, cracks may be formed in the module cover 200 or the rigidity may be weakened. Accordingly, it is preferable that the module cover 200 has a small through hole or a small hole.
The source PCB 172 may be located with signal wires for transmitting timing control signals and digital video data transmitted from the timing controller board. The source PCB 171 may be connected to the display panel 100 by a source COF (Chip On Film).
The source COF may be electrically connected to the source PCB 172 and the data pads of the display panel 100. The source COF can be implemented with a data integrated circuit (Integrated Circuit).
A PCB cover 400 may be provided on the rear side of the area where the source PCB 172 is located. The PCB cover 400 may prevent the source PCB 172 from being exposed to the outside. The PCB cover 400 may be opaque so that the source PCB 172 is not exposed to the outside.
PCB cover 400 may include an insulating material such that source PCB 172 is not interfered with by other electronic devices. Accordingly, the PCB cover 400 can protect the source PCB 172 from a leakage current.
The body 10 of the display device according to the present invention can support the display panel 100 only by the module cover 200. [ In other words, the body 10 may not have a cover other than the module cover 200. Accordingly, the user can feel that the thickness of the body 10 is very thin, and can concentrate more on the display screen.
Referring to FIG. 2, the display panel 100 may include a transparent substrate 110, an upper electrode 120, an organic light emitting layer 130, and a lower electrode 140. The transparent substrate 110, the upper electrode 120, the organic light emitting layer 130, and the lower electrode 140 may be sequentially formed.
The transparent substrate 110 and the upper electrode 120 may include a transparent material. The lower electrode 140 may include a material that is not transparent. The lower electrode 140 may include a transparent material (for example, ITO or the like). In this case, light may be emitted to one surface of the lower electrode 140.
When a voltage is applied to the upper and lower electrodes 120 and 140, light emitted from the organic light emitting layer 130 may pass through the upper electrode 120 and the transparent substrate 110 and may be emitted to the outside. At this time, a light shielding plate may be further formed behind the lower electrode 140 to emit light emitted to the lower electrode 140 to the front surface.
The display device 100 according to the present invention may be an OLED display device. Accordingly, a separate light source is not required, and the volume and weight of the display device 100 can be reduced. In addition, the OLED display device has a response speed that is 1000 times faster than that of the liquid crystal display device, so that no afterimage may remain when displaying an image.
Referring to FIG. 3, the display panel 100 and the module cover 200 may be attached to the display device according to the present invention through the adhesive layer 350. The adhesive layer 350 may include a double-sided tape capable of bonding both surfaces together.
The adhesive layer 350 may have a different thickness. Accordingly, foreign matter or dust may enter between the display panel 100 and the module cover 200. In order to prevent this, as shown in Fig. 3 (a), the sealing member 183 can be side-sealed to at least one side of the adhesive layer 350. [ The sealing member 183 can shield at least one side of the adhesive layer 350 and the display panel 100 at the same time.
As another example, a frame 187 may be inserted into at least one side of the adhesive layer 350, as shown in Fig. 3 (b). The frame 187 may contact the at least one side of the adhesive layer 350 and may be bent so that one end extends toward the display panel 100. Accordingly, at least one side of the display panel 100 can be simultaneously shielded.
As another example, the middle cabinet 193 may be positioned between the display panel 100 and the module cover 200, as shown in FIG. 3 (c). The middle cabinet 193 can guide the position where the display panel 100 is coupled. The middle cabinet 193 can be inserted between the display panel 100 and the module cover 200 with the flange 193a. The middle cabinet 193 may shield at least one side of the display panel 100 and the module cover 200 at the same time.
The flange 193a of the middle cabinet 193 may be spaced apart from the adhesive layer 350. Accordingly, since the adhesive layer 350 does not have to be entirely disposed on the display panel 100, the amount of the adhesive layer 350 required when the display device is manufactured can be reduced.
As another example, an edge portion of the module cover 200 may be bent toward the display panel 100, as shown in Fig. 3 (d). Since the edge portion of the module cover 200 is bent, at least one side of the adhesive layer 350 can be shielded from the outside.
In this case, other materials may not be included between the display panel 100 and the module cover 200. Thus, the manufacturing process of the display device is simplified, and the cost can be saved. Further, the edge of the module cover 200 may be spaced apart from the adhesive layer 350. Accordingly, since the adhesive layer 350 does not have to be entirely disposed on the display panel 100, the amount of the adhesive layer 350 required when the display device is manufactured can be reduced.
In the following embodiments, the adhesive layer 350 and side structures are omitted for convenience of explanation. The adhesive layer 350 and the structures located on the side surface are applicable to other embodiments.
Referring to FIG. 4, the display device according to the present invention may include a housing 500 electrically connected to the body 10.
The housing 500 may shield the components that drive the display device. For example, the housing 500 may shield at least one printed circuit board (PCB). A detailed coupling structure and a coupling method of at least one printed circuit board will be described later.
The housings 500 may be spaced apart from each other without contacting the body 10. That is, it means that the housing 500 may not be positioned on the display screen display portion. Accordingly, the user can concentrate more on the display screen.
For example, as shown in FIG. 4 (a), the housing 500 may be connected to the body 10 through a plurality of FFCs (Flat Flex Cables) 161. The FFC 161 may include a plurality of signal connection terminal pins and at least one ground terminal pin for connecting the housing 500 and the body 10. [ The FFC 161 is advantageous in cost compared to other cables.
As another example, as shown in Fig. 4 (b), the housing 500 can be coupled to the body 10 through a single circular cable 163. That is, in FIG. 3 (b), it is meant that the electric signals connected to the plurality of FFCs 161 can be connected through a single circular cable 163. Since the housing 500 and the body 10 are connected through a single circular cable 163 rather than a plurality of circular cables 163, the user can feel that the appearance is cleaner.
As another example, as shown in FIG. 4C, the housing 500 and the body 10 can exchange electric signals wirelessly. In this case, the user may feel that the appearance is cleaner than when the housing 500 and the body 10 are connected to each other through the FFC 161 or the circular cable 163.
In the display device according to the present invention, the body 10 and the housing 500 may be spaced apart from each other. Accordingly, the user can concentrate more on the display screen and can implement a display device having a thinner body 10.
Referring to FIG. 5, at least one PCB may be positioned inside the housing 500. Each PCB may be spaced apart.
For example, the at least one PCB may be the main board 109. The main board 109 may provide an interface for the display device to operate. In addition, the main board 109 can check and manage the operating states of the respective components of the display apparatus to make them optimal.
As another example, the at least one PCB may be a power supply 107. The power supply 107 may supply power to the display device. The power supply 107 can change the AC frequency to a DC frequency. That is, the power supply 107 changes the low frequency to the high frequency, which means that the electric efficiency can be increased.
As another example, the at least one PCB may be the timing controller board 105. The timing controller board 105 can transmit an input signal to the display panel 10. That is, the timing controller board 105 means that the timing signals (CLK, LOAD, SPi) for controlling the source PCB and the video signals (R, G, B) can be transmitted to the source PCB. In addition, the timing controller board 105 can control an image. The timing controller board 105 may be connected to the source PCB through any one of an FFC, a circular cable, and a wireless transmission.
5A, the main board 109 may be spaced apart from the center portion and the right side of the housing 500. The power supply 107 may include a main board 109 located on the right side, (E.g., in the direction of the major axis of the housing 500) with respect to the center of the housing 500.
The timing controller board 105 may be located on the upper surface of the main board 109 and the power supply 107. [ Since the timing controller board 105 is located on the upper surface of the main board 109 and the power supply 107, the internal space of the housing 500 can be saved.
Although not shown, a titanium shield may be attached to a position where the timing controller board 105 is to be mounted to prevent electromagnetic waves emitted from the power supply 107 and the main board 109. [ That is, it means that the timing controller board 105 can be coupled onto the titanium shield, not the power supply 107 and the main board 109. Accordingly, the power supply 107 and the main board 109 and the timing controller board 105 may not interfere with each other. In addition, the titanium shield can protect the timing controller board 105 from impact.
The timing controller board 105 may be overlapped with the power supply 107 and the main board 109 in the height direction of the housing 500. Accordingly, the timing controller board 105 can be more easily combined with the power supply 107 and the main board 109. [
Alternatively, as shown in FIG. 5B, one main board 109 may be mounted inside the housing 500. That is, the main board 109 is located on one side of the housing 500, and the power supply 107 can be positioned facing the main board 109 and the housing 500 in the longitudinal direction of the main board 109.
The display apparatus according to the present invention can save space because the timing controller board 105 is located above the power supply 107 and the main board 109. [ Accordingly, the user can feel that the entire size of the housing 500 has been reduced and improved in appearance.
Referring to FIG. 6, the display device according to the present invention may include a speaker 117 on both sides of the front surface of the housing 500. The speaker 117 can output and transmit sound to the user. Thus, it may be more efficient for the speaker 117 to be located on the front surface of the housing 500. [
As shown in FIG. 6A, the speaker 117 may be mounted on the front surface of the housing 500, spaced apart from at least one PCB mounted inside the housing 500. Alternatively, as shown in FIG. 6 (b), the speaker 117 may be located apart from the housing 500. Since the speaker 117 is located outside the housing 500, the user can place the speaker 117 at a position where sound can be transmitted to the user. The speaker 117 may be located on both sides of the display device body 10.
The display device according to the present invention may be configured such that the speaker 117 is positioned on both sides of the front surface or the outside of the housing 500. Thus, the user can receive the sound of the display device more easily.
Referring to FIG. 7, a display device according to the present invention can be coupled to a display device in various ways by a source PCB 172 and a PCB cover 400. Depending on the positional relationship in which the source PCB 172 and the PCB cover 400 are coupled, the backside of the display device can be flat or nearly flat.
For example, as shown in FIG. 7A, the source PCB 172 and the PCB cover 400 may be positioned on the rear surface of the display panel 100 where the module cover 200 is not located. In this case, the thickness of the body 10 where the source PCB 172 is located may be equal to or similar to the thickness of the body 10 where the module cover 200 is located. Accordingly, the rear surface of the body 10 can be flat or almost flat. Therefore, the body 10 can be brought into tight contact with the surface to be attached.
As another example, the source PCB 172 and the PCB cover 400 may be positioned on the front surface of the module cover 200 where the display panel 100 is not positioned, as shown in FIG. 7 (b). In this case, since the source PCB 172 and the PCB cover 400 are located on the front surface of the module cover 200, the back surface of the body 10 can be flat. Accordingly, the body 10 can be brought into tight contact with the surface to be attached.
As another example, the source PCB 172 and the PCB cover 400 may be located in a groove formed in the back surface of the module cover 200, as shown in Fig. 7 (c). In this case, at least a part of the PCB cover 400 may protrude in the rear direction of the module cover 200. Accordingly, the rear surface of the body 10 may not be perfectly parallel. However, since the source PCB 172 and the PCB cover 400 are located inside the grooves, the protruding portion is very small and the body 10 may not be a problem in attaching to the surface to be attached. However, depending on the extent to which the source PCB 172 and the PCB cover 400 are projected, there may be a problem that the body 10 is tightly engaged with the surface to be bonded.
As another example, the source PCB 172 and the PCB cover 400 may be located on the back side of the module cover 200, as shown in FIG. 7 (d). In this case, the source PCB 172 and the PCB cover 400 may protrude from the rear surface of the module cover 200. As a result, there is a problem in that the body 10 is engaged with the attached surface.
As another example, the source PCB 172 may be located on the backside of the module cover 200, as shown in Figure 7 (e). In this case, since the PCB cover 400 is not positioned and the source PCB 172 protrudes to the rear surface of the body 10, it may not be directly coupled to the attached surface.
The body 10 shown in Figs. 7 (a) and 7 (b) can be directly attached to the surface to be attached without any combination of other apparatus and structure. However, the body 10 shown in Figs. 7 (c), 7 (d), and 7 (e) may require coupling of other devices and structures to the body 10 or the attached surface. The combination of other devices and structures will be described later.
The display device according to the present invention can change the structure of the display panel 100 and the module cover 200 to make the rear surface flat or almost flat. Thus, a thin and flat display device can be realized.
8 to 11 are views showing the relationship between the body and the attached surface of the display device according to the present invention.
Referring to FIG. 8, the display device according to the present invention can be coupled to or separated from the attached surface 700 of the body 10. That is, the display device means that the first state in which the body 10 and the attached surface 700 are coupled and the second state in which the body 10 and the attached surface 700 are separated.
In the first state, the entire back surface portion of the body 10 can have the same width. That is, the width LCW in the thickness direction of the PCB cover 400 is smaller than the widthwise width MCW of the module cover 200 in order that the rear surface of the body 10 is closely contacted with the surface- Which may be the same or smaller. Accordingly, the body 10 and the surface-to-be-attached 700 can be tightly coupled without being disturbed by the PCB cover 400.
The width LCW in the thickness direction of the PCB cover 400 may be larger than the width SPW in the thickness direction of the source PCB 172 and the thickness PCW of the PCB cover 400. [ Accordingly, the source PCB 172 can be spaced apart from the PCB cover 400 inside the PCB cover 400. Accordingly, the source PCB 172 may not be interfered with by the PCB cover 400.
The display device according to the present invention can be tightly coupled with the attached surface 700 because the rear surface of the body 10 is flat without being projected. Accordingly, the user can concentrate more on the display screen.
Referring to FIG. 10, the PCB cover 400 of the body 10 may protrude rearward in the display device according to the present invention. In detail, the rear surface of the body 10 may protrude from the module cover 200 by the thickness PCW of the PCB cover 400. [ Accordingly, different materials or structures may be required for the body 10 to be tightly coupled to the attached surface 700.
The attached surface 700 may include a fourth engaging portion 146. The fourth engaging portion 146 may protrude from the front surface of the attached surface 700. [ The thickness MGW of the fourth engaging portion 146 facing the front surface of the attached surface 700 may be equal to or greater than the thickness PCW of the PCB cover 400. [ Accordingly, the body 10 can be coupled through the fourth coupling portion 146 without being directly attached to the attachment surface 700. [ The PCB cover 400 can be in contact with the fourth engaging portion 146 included in the attached surface 700 without contacting the attached surface 700. [ That is, the body 10 can be coupled to the attached surface 700 in parallel. A detailed description of the coupling portion will be given later.
The display device according to the present invention may have the thickness MGW of the fourth coupling portion 146 equal to or greater than the thickness LCW of the PCB cover 400. [ Accordingly, the PCB cover 400 does not contact the attached surface 700, so that the body 10 and the attached surface 700 can be coupled in parallel.
Referring to FIG. 10, the display device according to the present invention may include a bracket 20 to which an attached surface 700 is attached. The bracket 20 may be positioned on the front surface of the attached surface 700. The bracket 20 may be positioned at a portion that does not correspond to the PCB cover 400 in the first state. That is, the PCB cover 400 does not contact the bracket 20 in the first state. The thickness PW of the bracket 20 may be equal to or greater than the thickness LCW of the PCB cover 400. [ In this case, since the PCB cover 400 may not contact the attached surface 700, the body 10 and the attached surface 700 can be coupled in parallel.
The thickness PW of the bracket 20 may be equal to or greater than the thickness LCW of the PCB cover 400. [ Accordingly, the PCB cover 400 does not contact the attached surface 700, so that the body 10 and the attached surface 700 can be coupled in parallel.
11, the display device according to the present invention is not limited to the case where the rear surface of the body 10 is flat, as shown in FIG. 10 (a) Even if at least a part of the rear surface of the body 10 protrudes, it can be coupled in parallel with the attached surface 700 by another structure. Accordingly, the user can concentrate more on the display screen. Further, since the body 10 and the surface-to-be-attached 700 are in tight contact with the surface-to-be-attached 700, the binding force can be stronger than when the body 10 and the surface-to-be-
Although the embodiments of the present invention will be described in detail with reference to the accompanying drawings, it is to be understood that the present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof.
12 to 35 are views showing various embodiments of a display device according to the present invention.
12, the display device according to the present invention includes the body 10 including the first and second engaging portions 112 and 144, and the attached surface 700 includes the third and fourth engaging portions 144 and 146 ). The first coupling portion 112 and the third coupling portion 114 may be coupled to each other in the first state and the second coupling portion 144 and the fourth coupling portion 144 may be coupled to each other in the first state.
The first and third coupling portions 112 and 144 may be spaced apart from the second and fourth coupling portions 114 and 146. For example, the first and third coupling portions 112 and 144 may be located on the rear upper surface of the body 10 and the second and fourth coupling portions 114 and 146 may be positioned on the lower rear surface of the body 10 .
The features of the first to fourth coupling portions 112, 114, 144, and 146 described above may be applied to other embodiments described later.
The first engagement portion 112 may include a first hook and the second engagement portion 114 may include a second hook. The first hook may protrude rearward of the body 10 and the second hook may protrude forward of the attachment surface 700. [ The first hook and the second hook can be engaged with each other in the first state.
The first hook may include a first protrusion protruding rearward of the body 10 and a second protrusion connected to the first protrusion and protruding in a direction perpendicular to the first protrusion. The second hook may include a third protrusion protruding forward from the attached surface 700 and a fourth protrusion connected to the third protrusion and protruding in a direction perpendicular to the first protrusion. The protruding directions of the second protrusion and the fourth protrusion may be opposite to each other.
The third coupling portion 144 may be a flat shape that does not protrude from the body 10. The third coupling portion 144 may include the same material as the module cover. The fourth engaging portion 146 may protrude forward of the attached surface 700. [ The fourth coupling portion 146 may include a magnetic material. Since the third coupling portion 144 includes a metal material, the third coupling portion 144 can be coupled with the magnetic coupling fourth coupling portion 146 in the first state.
The combined width SD of the first engaging portion 112 and the third engaging portion 114 in the first state may be equal to the combined width of the second engaging portion 144 and the fourth engaging portion 146 have. In this case, the combined width of the second engaging portion 144 and the fourth engaging portion 146 may be the same as the width MGW of the fourth engaging portion 146. Since the bonded widths between the engaging portions are the same, the body 10 and the attached surface 700 can be joined in parallel.
In the display device according to the present invention, the first and second coupling portions 112 and 114 may be coupled by hooks and the third and fourth coupling portions 144 and 146 may be coupled by magnetic force. As a result, the body 10 and the attached surface 700 may not be separated more easily when they are combined by the magnetic force. Further, since the position is guided by the first and second hooks, the body 10 can be accurately engaged with a desired position of the attached surface 700. [
Referring to FIG. 13, the display device according to the present invention can divide the first and second coupling portions 112 and 114 in the longitudinal direction of the body 10. That is, the first and second coupling portions 112 and 114 may include a plurality of hooks.
The display device according to the present invention can guide the body 10 to the attached surface 700 at a more accurate position than when the first and second coupling portions 112 and 114 are formed as one unit.
Referring to FIG. 14, the third and fourth coupling portions 144 and 146 of the display device according to the present invention may have various shapes.
For example, as shown in FIG. 14 (a), the third and fourth coupling portions 144 and 146 may be located in most areas except for the first and second coupling portions 112 and 114. In detail, the fourth coupling portion 146 may connect the entire body 10 from a portion immediately below the region where the first and second coupling portions 112 and 114 are located. In this case, since the area of the fourth magnetic coupling part 146 is large, the coupling force may be stronger than when the area is small. Accordingly, the body 10 may not be easily separated from the attached surface 700.
As another example, the third and fourth coupling portions 144 and 146 may be separated into a plurality of in the short axis direction of the body 10, as shown in Fig. 14 (b). In detail, the fourth coupling portion 146 may be positioned at a lower portion of the rear side of the body 10, and the other may be positioned at a rear center portion of the body 10. In this case, the magnetically coupled fourth coupling portion 146 can couple the body 10 and the attached surface 700 at various portions. Accordingly, the body 10 may not be separated more easily than when the body 10 is engaged by one fourth coupling portion 146 on the attachment surface 700. [
As the third and fourth coupling portions 144 and 146 have various shapes, the display device according to the present invention can more strongly combine the body 10 and the attachment surface 700.
Referring to FIG. 15, the third and fourth coupling portions 144 and 146 of the display device according to the present invention may have various shapes.
As shown in FIG. 15 (a), the third engaging portion 144 may not protrude rearward of the body 10. In this case, the projected width MGW of the fourth engaging portion 146 may be a combined width of the third engaging portion 144 and the fourth engaging portion 146. [
Alternatively, as shown in FIG. 15 (b), the third engaging portion 144 may protrude rearward of the body 10. The third coupling portion 144 may include a magnetic material and may have an opposite polarity to the material of the fourth coupling portion 146. [ However, the present invention is not limited thereto, and the third coupling portion 144 may be made of a metal material such as a module cover. In this case, the sum of the protruded width TMGW2 of the third engaging portion 144 and the protruded width TMGW1 of the fourth engaging portion 146 is greater than the sum of the third engaging portion 144 and the fourth engaging portion 146, Lt; / RTI >
When the third coupling portion 144 includes a material having a polarity opposite to that of the fourth coupling portion 146, the coupling force between the body 10 and the attachment surface 700 can be further improved as compared with the case of a metal material. Accordingly, the body 10 and the attached surface 700 may not be easily separated.
Referring to FIG. 16, the display device according to the present invention may include first to fourth coupling portions 112, 114, 144, and 146, all of which are hooks.
For example, the first and third coupling portions 112 and 144 may include a first hook, and the second and fourth coupling portions 114 and 146 may include a second hook. Accordingly, the first to fourth engagement portions 112, 114, 144, and 146 can be engaged by the hooks.

The display device according to the present invention can closely contact the body 10 and the attached surface 700 because the second and fourth coupling portions 114 and 146 are recessed into the attached surface 700. Also, since the first and third coupling portions 112 and 144 include the first hook, the body 10 and the attachment surface 700 can be easily separated or combined.
Referring to FIG. 26, in the display device according to the present invention, the first and third coupling portions 112 and 144 may be recessed into the module cover 200.
The second and fourth engaging portions 114 and 146 may include a second hook protruding forward from the attached surface 700. The first and third coupling portions 112 and 144 may be recessed in conformity with the shape of the second hook so that the second hook can be inserted.

The length WD1 of the fourth protrusion is equal to or greater than the length WD2 of the inlet of the depression so that the second and fourth coupling portions 114 and 146 can be inserted into the first and third coupling portions 112 and 144 Can be small.
Since the first and third coupling portions 112 and 144 are recessed into the module cover 200, the body 10 and the attached surface 700 can be tightly coupled. Further, since the second and fourth coupling portions 114 and 146 include the second hook, the body 10 and the attachment surface 700 can be easily separated or combined.
Referring to Fig. 27, the display device according to the present invention may have the second engaging portion 114 attached to the attached surface 700 in various manners.
For example, as shown in FIG. 27 (a), the second engaging portion 114 may be attached to one surface of the front surface of the attached surface 200. The second engaging portion 114 can be engaged with the attached surface 200 using either a double-sided tape, an adhesive, or a screw. The second coupling portion 114 may have the same or similar material as the attachment surface 700. In this case, the second engaging portion 114 can be attached without touching the attached surface 700. Thus, the cost can be saved.
Alternatively, as shown in FIG. 27 (b), the second engaging portion 114 may be formed integrally with the attached surface 700. In this case, the second protrusion can be directly protruded from the attached surface 700. The second engaging portion 114 may not be separated from the attached surface 700 because the attached surface 700 and the second engaging portion 114 are integrally formed
Alternatively, as shown in FIG. 27 (c), the second coupling portion 114 may include a magnetic material. In this case, the body 100 and the attached surface 700 are more easily coupled, and the position where the body 100 is to be coupled can be more accurately guided.
Although only the second engaging portion 114 is shown in this figure, the fourth engaging portion 146 may be coupled to the attached surface 700 in the same or similar manner.
Referring to FIG. 28, the display device according to the present invention may have a button 542 disposed on one side thereof. The button 542 may be a push button or a touch button. Button 542 may change from the first state to the second state when the first operation is applied by the user. For example, the first operation may be a touch or push operation of the user.
The first and third coupling portions 112 and 144 may include electromagnets. That is, the first and third coupling parts 112 and 144 may include a material which is magnetized when current flows and a material whose magnetism disappears when current is interrupted. The button 542 may cause the current flowing through the first and third coupling portions 112 and 144 to be blocked when a first operation is applied by the user. As a result, the first and third coupling portions 112 and 144 are separated from the second and fourth coupling portions 114 and 146, respectively.
In the display device according to the present invention, the first and third coupling portions 112 and 144 may include electromagnets. Accordingly, it is possible to easily change from the first state to the second state only by operating the button 542. [
Referring to FIG. 29, the display device according to the present invention may include a first engaging portion 112 and a third engaging portion 144, which may include a first hook and an electromagnet.
The first engaging portion 112 may be inserted into and engaged with the second engaging portion 114 recessed into the attached surface 700 and the third engaging portion 144 may be engaged with the inner surface of the attached surface 700 And the fourth coupling portion 146 inserted with a magnetic substance is inserted into the recessed portion.
When the user applies the first operation to the button 542, the current flowing to the third coupling part 144 can be cut off. Accordingly, the third engaging portion 144 and the fourth engaging portion 146 can be separated from each other. However, in this case, the first engaging portion 112 and the second engaging portion 114 may still be engaged. Accordingly, the first engaging portion 112 and the second engaging portion 114 can be separated from each other in order to change from the first state to the second state.
In the display device according to the present invention, only the third coupling portion 144 may include an electromagnet. Accordingly, when the user presses the button 542, the body 10 may not fall off the attached surface 700. Further, since the first engaging portion 112 is hooked, it can be guided to a position where it is to be engaged.
Referring to FIG. 30, in the display device according to the present invention, the first and third coupling portions 112 and 144 may include rails, and the second and fourth coupling portions 114 and 146 may include guide rails.
The rails protrude rearward of the body 10 and the guide rails can sink into the inside of the attached surface 700. The cross-sectional structure of the rail is the same as the cross-sectional structure of the guide rail, so that the body 10 may not be easily separated from the attached surface 700 after being coupled. Also, the body 10 may not be shaken after coupling.
The rails can extend to the side of the body 10, unlike the hooks described above. The rails may be integrally formed with the body 10 and separately formed from the body 10. The guide rails can also extend to the side of the attached surface 700. Accordingly, when the state changes from the second state to the first state, the rails and the guide rails can slide in the side surfaces. That is, the rail and the guide rail mean that the body 10 can be moved to the side surface of the attached surface 700 and can be laterally inserted.
The display device according to the present invention can be slidably coupled to the guide rail using a rail. Thus, the body 10 and the attached surface 700 can be joined more strongly.
Referring to FIG. 31, the display device according to the present invention may be divided into a plurality of first and third coupling portions 112 and 144 in the longitudinal direction of the body 10. That is, the first and third coupling portions 112 and 144 may include a plurality of rails. In this case, the second and fourth coupling portions 114 and 146 can be recessed into the attached surface 700. The rail may include a first protrusion protruding rearward of the body 10 and a second protrusion connected to the first protrusion and protruding in a direction perpendicular to the first protrusion.
The width of the recessed entrance of the attachment surface 700 may differ at least in part from the other portions. For example, the width RD2 of the second and fourth engaging portions 114 and 146 at the portion where the rails are inserted is set such that the rails are not separated from the guide rails, (TD2). The width RD1 of the second and fourth coupling portions 114 and 146 in the portion where the rail is not inserted is set to be smaller than the width RD1 of the first and third coupling portions 112 and 144 so that the rail can be easily coupled to the guide rail. 2 < / RTI >
In the display device according to the present invention, the width of the recessed entrance of the second and fourth coupling portions 114 and 146 may be different at least in part from the other portions. Accordingly, even if the body 10 is not moved to the side surface of the attached surface 700, it can be moved only to the portion where the rail is not inserted and slide-coupled.
Referring to FIG. 32, the first engaging portion 112 of the display device according to the present invention may protrude toward the upper side of the body 10. In this case, the second engaging portion 114 may protrude toward the front surface of the attached surface 700. The protruding portion of the second coupling portion 114 may be depressed upward to engage with the first coupling portion 112. Accordingly, the protruding direction of the first engaging portion 112 can be orthogonal to the protruding direction of the second engaging portion 114. The protruding cross-sectional structure of the first engaging portion 112 and the recessed cross-sectional structure of the second engaging portion 114 may be the same.
The third and fourth coupling portions 144 and 146 may be formed by inserting a magnetic material into a portion of the body 10 or the attachment surface 700 that is recessed. The width of the third and fourth coupling portions 144 and 146 that are embedded into the body 10 or the attachment surface 700 may be equal to or greater than the width of the inserted magnetic material. Accordingly, the third and fourth coupling portions 144 and 146 may not protrude rearward of the module cover 200.
In the display device according to the present invention, the second coupling portion 114 may be located above the body 10 in the first state. Accordingly, the user can feel that the step between the body 10 and the attached surface 700 is less. In addition, the body 10 can be slidably engaged without making depressions on the attached surface 700 itself, thus saving the cost.
Referring to FIG. 33, in the display device according to the present invention, the first engaging portion 112 protrudes upward from the body 10, and the third engaging portion 144 protrudes downward from the body 10. In this case, the second and fourth coupling portions 114 and 146 may protrude toward the front surface of the attachment surface 700. Accordingly, the protruding direction of the first and third coupling portions 112 and 144 can be orthogonal to the protruding direction of the second and fourth coupling portions 114 and 146. The protruding portion of the second coupling portion 114 may be depressed upward to engage with the first coupling portion 112. In addition, the protruding portion of the fourth engaging portion 146 may be depressed downward to engage with the third engaging portion 144. The protruding sectional structure of the first and third coupling portions 112 and 144 and the recessed sectional structure of the second and fourth coupling portions 114 and 146 may be the same.
The display device according to the present invention can freely separate and connect the body 10 with the surface 700 to be attached if the second and fourth coupling parts 114 and 146 are provided on the attachment surface 700. [ Accordingly, the user can freely and tightly connect the body 10 where necessary. In addition, in the first state, the second and fourth coupling portions 114 and 146 may be positioned above and below the body 10. Accordingly, the user can feel that the step between the body 10 and the attached surface 700 is less.
34 and 35, the first engaging portion 112 protrudes upward from the body 10, and the third engaging portion 144 protrudes downward from the body 10. In this case, the second and fourth coupling portions 114 and 146 may protrude toward the front surface of the attachment surface 700. The protruding portion of the second coupling portion 114 may be depressed upward to engage with the first coupling portion 112. In addition, the protruding portion of the fourth engaging portion 146 may be depressed downward to engage with the third engaging portion 144.
The protruding sectional structure of the first and third coupling portions 112 and 144 and the recessed sectional structure of the second and fourth coupling portions 114 and 146 may be different from each other. That is, the first and third coupling portions 112 and 144 may not be engaged with the second and fourth coupling portions 114 and 146 in the first state. Accordingly, the first and third coupling portions 112 and 144 may remain in the second and fourth coupling portions 114 and 146 even in the first state.
As shown in FIG. 35 (a), at least one of the first and third coupling portions 112 and 144 may be inserted into the body 10, and then the other one may be inserted and coupled. Since the first and third coupling portions 112 and 144 are movable in the second and fourth coupling portions 114 and 146, (114, 146). Accordingly, the user can easily couple the body 10 to the attached surface.
Alternatively, as shown in FIG. 35 (b), the first and third coupling portions 112 and 144 may be slidably engaged with the second and fourth coupling portions 114 and 146. The first and third engaging portions 112 and 144 may be inserted into the second and fourth engaging portions 114 and 146 by moving the body 10 to the side of the attached surface 700. [ That is, it means that the body 10 can slide on the attached surface 700.
The display device according to the present invention can couple the first and third coupling portions 112 and 144 to the second and fourth coupling portions 114 and 146 in a sequential or sliding manner. Accordingly, it is possible to freely separate and combine by selecting a method that the user is comfortable with.
36 to 46 are views showing various other embodiments of the display device according to the present invention.
Referring to FIG. 36, the display device according to the present invention can engage with the bracket 20 of the body-mounted surface 700 of the body 10.
The bracket 20 is positioned on the front surface of the attached surface 700 and can directly engage with the body 10 in the first state. In detail, the bracket 20 can contact at least a portion of the module cover in the first state. The bracket 20 can be coupled to the attached surface 700 through at least one screw. When the body 10 is coupled to the body 10 through the bracket 20, it is not necessary to form a depression on the attached surface 700 or mount the protrusion separately, so that it is convenient to separate and fasten the body 10 and the cost can be reduced. In addition, since the bracket 20 is thin, users can recognize that the body 10 is tightly coupled to the attached surface 700.
37, the display device according to the present invention is characterized in that the bracket 20 includes second and fourth coupling portions 114 and 146, a coupling hole 451, a PCB hole 423, a PCB groove 448, (377). The second and fourth coupling portions 114 and 146 may be the same as or similar to the second and fourth coupling portions 114 and 146 of the above-described embodiments.
The coupling hole 451 may be located on the upper portion of the second coupling portion 114. The coupling hole 451 passes through the bracket 20 and the first coupling portion can be inserted through the coupling hole 451. Accordingly, the engaging hole 451 may be located at a position corresponding to the first engaging portion in the first state.
And the PCB hole 423 may be positioned on both sides of the lower portion of the fourth engaging portion 146. [ The PCB hole 423 penetrates the bracket 20 and can receive the source PCB. Accordingly, the PCB hole 423 may be located at a portion corresponding to the source PCB in the first state. The PCB holes 423 can receive the source PCBs located on both sides of the bottom of the body. The PCB holes 423 can prevent the source PCB from contacting the attached surface.
The PCB groove 448 may be located at the bottom center of the fourth coupling portion 146. The PCB grooves 448 may be a structure in which the PCB grooves 448 are downwardly bent, unlike the PCB holes 423. That is, the PCB grooves 448 may not be surrounded by the bracket 20. The PCB grooves 448 may receive the source PCB. Accordingly, the PCB grooves 448 can be located in the portion corresponding to the source PCB in the first state. The PCB grooves 448 can receive the source PCB located in the bottom center of the body. The PCB grooves 448 can prevent the source PCB from contacting the attached surface.
The screw groove 377 may be located at the vertex of the bracket 20 and at the center of both side edges. The screw groove 377 penetrates the bracket 20 and can couple the bracket 20 and the attached surface 700 together. The bracket 20 can engage the attached surface 700 using at least one screw through the screw groove 377. However, the present invention is not limited thereto, and the bracket 20 may be coupled to the attached surface 700 using a double-sided tape. In this case, the screw groove 377 may not be positioned.
Referring to FIG. 38, a convex portion 368 may be positioned on three side edges except the lower side of the bracket 20. The convex portion 368 can protrude toward the body 10 in the first state.
The width SW1 in the direction toward the body of the convex portion 368 may be equal to or smaller than the width SW2 in the direction toward the body of the second engaging portion 114. [ Accordingly, when the second engaging portion 114 and the first engaging portion are engaged, the body may not contact the convex portion 368. When the body contacts the convex portion 368, the first and second engaging portions 114 and 114 may be difficult to engage with each other.
The convex portion 368 may be formed to have a different thickness in the thin bracket 20. Thus, the rigidity of the bracket 20 can be improved. Also, the convex portion 368 can support the rear surface of the body 10 in the first state. As a result, the convex portion 368 can prevent the body 10 from easily cracking.
Referring to FIG. 39, the display device according to the present invention may have the convex portion 368 of the bracket 20 positioned on the bracket 20 in various structures.
For example, as shown in Fig. 39 (a), the convex portion 368 located on the upper side of the bracket 20 can be separated into a plurality of portions. As another example, as shown in FIG. 39 (b), the convex portions 368 located on both sides of the bracket 20 can be separated into a plurality of portions. As another example, as shown in Fig. 39 (c), the convex portions 368 located on the upper side and the both sides of the bracket 20 can be separated into a plurality of portions. In this case, the bracket 20 can be bent more than when the convex portions 368 are connected together. Thus, the rigidity of the bracket 20 can be further improved. It is possible to improve the rigidity of a desired portion by dividing the convex portion 368 of the bracket 20 where a large rigidity is required.
As another example, as shown in Fig. 39 (d), the convex portions 368 located on all sides can be connected to each other. In this case, it is more convenient to form the convex portion 368 on the bracket 20. Thus, the manufacturing process of the bracket 20 is simplified and the cost can be saved.
Referring to FIG. 40, the display device according to the present invention may further include a bracket 20 and a heat sheet 715. The heat sheet 715 can extend in the minor axis direction of the bracket 20 with the coupling hole 451 as an axis. At least a portion of the heat sheet 715 may be positioned on the fourth engaging portion 146. [ One end of the heat sheet 715 may be located above the fourth engaging portion 146 and the other end may be positioned above the PCB hole 423 or the PCB grooves 448.
The heat sheet 715 may include a material having a higher thermal conductivity than the bracket 20. Accordingly, the heat sheet 715 may be a path through which the heat of the source PCB emitted from the PCB hole 423 or the PCB groove 448 is transmitted. The heat of the source PCB which is emitted from the PCB hole 423 or the PCB groove 448 may escape to the coupling hole 451 through the heat sheet 715 as shown in Figure 38 (b).
The heat sheet 715 may not be positioned between the upper portion of the PCB hole 423 or the PCB groove 448 and the fourth engaging portion 146 at a position where an electric wiring to be described later is to be positioned. In this case, the heat of the source PCB and the electric wiring can escape through the heat sheet 715 to the coupling hole 451.
In the display device according to the present invention, the heat sheet 715 may be positioned on at least a part of the bracket 20. Accordingly, the heat introduced into the bracket 20 can be discharged to the coupling hole 451 through the heat sheet 715.
Referring to FIG. 41, the display device according to the present invention can be positioned in various ways with the heat sheet 715 of the bracket 20.
For example, as shown in FIG. 41A, the heat sheet 715 located at the center of the bracket 20 among the plurality of heat sheets 715 may be connected to the heat sheet 715 located at the edge. That is, the heat sheet 715 extending to the upper side of the PCB groove 448 can be connected to the heat sheet 715 extending upward from the PCB hole 423. 41 (b), the heat sheet 715 located at the edge of the bracket 20 among the plurality of heat sheets 715 may be connected to the heat sheet 715 located at the center. That is, the heat sheet 715 extending to the upper side of the PCB hole 423 can be connected to the heat sheet 715 extending upward from the PCB groove 448.
In the above-described embodiment, since the heat sheet 715 of all the portions does not extend upward and is connected to other portions, the fourth engaging portion 146 may not be hindered from being bonded to the body by magnetism. For example, in the embodiment shown in FIG. 41 (a), the central portion of the fourth engaging portion 146 can be more strongly coupled with the body, and in the embodiment shown in FIG. 41 (b) Both sides of the body 146 can be more strongly coupled to the body.
As another example, as shown in Fig. 41 (c), the heat sheet 715 can be connected to each other. In detail, the heat sheet 715 may be connected to another heat sheet 715 located on both sides of the heat sheet 715. [ In this case, the area of the heat sheet 715 to which heat can be transferred can be increased. Further, when the heat is concentrated on one portion of the heat sheet 715, heat can be transferred to the other portion of the heat sheet 715. [ Accordingly, the heat introduced into the bracket 20 can easily dissipate through the engagement hole 451. [
The display device according to the present invention is capable of freely adjusting the arrangement of the heat sheet 715. Accordingly, it is possible to measure the distribution of the heat flowing into the bracket 20 and arrange the heat sheet 715 at an appropriate position.
Referring to FIG. 42, the display device according to the present invention may further include the bracket 20, the FFC 161. The FFC 161 may be positioned between the fourth coupling portion 146 and the PCB groove 448 or the PCB hole 423. [ The PCB connector 521 may be located at one end of the FFC 161 and the housing connector 523 may be located at the other end. The FFC 161 may transmit an electrical signal to and from the source PCB 172.
The PCB connector 521 may be connected to the source PCB 172 located in the center in the first state. That is, the PCB connector 521 is positioned above the center of the PCB groove 448. The electric wiring 521 may be attached to the bracket 20 by a double-sided tape and may be connected to the side edge.
The housing connector 523 may be located at a side edge of the bracket 20. [ The housing connector 523 can transmit a signal transmitted from the source PCB 172 to the outside. The housing connector 523 can connect a plurality of FFCs 161 together.
The display device according to the present invention can be connected to the side edge by attaching the FFC 161 to the bracket 20. Accordingly, the FFC 161 is not easily visible, and the user can concentrate more on the display screen. Also, since the housing connector 523 collects the FFCs 161 together, the appearance can be made more clean when connected with the housing.
Referring to FIG. 43, the first engaging portion 112 may include a hole recessed inside the body 10 to engage with the second engaging portion 114 on the upper side of the bracket 20. The first coupling portion 112 can penetrate the module cover 200 in the region corresponding to the second coupling portion 114 in the first state.
The third engaging portion 144 and the fourth engaging portion 146 may be formed by inserting a magnetic material into the body 10 and the portion recessed into the bracket 20. Accordingly, the third and fourth coupling portions 144 and 146 may be flat and not protruded from the body 10 and the bracket 20. In addition, the third and fourth coupling portions 144 and 146 may be separated into a plurality of portions in the short axis direction of the body. In detail, the third and fourth coupling portions 144 and 146 are positioned at the bottom of the rear surface of the body 10 and the bracket 20 and the other at the rear center portion of the body 10 and the bracket 20 can do. Accordingly, it can not be separated more easily than when it is coupled by one third and fourth coupling portions 144 and 146. [
The hole of the first coupling portion 112 can be caught by the hook of the second coupling portion 114. That is, as shown in FIG. 42 (a), in the first state, the groove upper surface of the first engaging portion 112 can be caught by the hook of the second engaging portion. Since the first engaging portions 112 should be located at portions corresponding to the second engaging portions 114, they may be separated from each other and divided into a plurality of portions.
Since the second engaging portion 144 is inserted into the first engaging portion 112 in the first state, the body 10 can be further tightly coupled to the bracket 20. Also, since the first engaging portion 112 is simply placed on the second engaging portion 144, it is easy to further separate the body 10 and the bracket 20 from each other.
Referring to FIG. 44, as shown in FIG. 44 (a), the first engaging portion 112 may be a recess that is partly recessed inwardly rather than a hole passing through the module cover 200. Accordingly, the display panel 100 can be protected by the module cover 200 at a portion where the first coupling portion 112 is located.
Also, the impact applied to the display panel 100 when the second coupling portion 114 is coupled to the first coupling portion 112 can be reduced.
The third engaging portion 144 of the body 10 does not protrude from the body 10 and may include the same material as the module cover 200 as shown in Figure 44 (b). Thus, the appearance of the rear surface of the module cover 200 in the second state can be made more clean.
The third and fourth coupling portions 144 and 146 may be located in most areas except for the first and second coupling portions 112 and 114 as shown in FIG. 44 (c). In detail, the third and fourth coupling portions 144 and 146 can connect the entire body 10 from a portion immediately below the region where the first and second coupling portions 112 and 114 are located. The third coupling portion 144 and the fourth coupling portion 146 may include materials having mutually opposite magnetic properties. 44 (d), the third engaging portion 144 may have the same metal material as the module cover 200. [ In this case, even if the size of the fourth coupling portion 146 is large and the third coupling portion 144 is not a magnetic material, it can be strongly coupled.
Referring to Figure 44 (e), the width of the hole of the first coupling portion 112 may be different from the inside to the outside. In detail, the width of the inside of the first engaging portion 112 may be smaller than the width of the outside. Accordingly, the second engaging portion 114 can be engaged with the portion of the first engaging portion 112 where the width of the first engaging portion 112 is changed.
Accordingly, the first engaging portion 112 and the second engaging portion 114 may not be easily separated from each other. In addition, the first engaging portion 112 and the second engaging portion 114 are engaged with each other, so that the engaging position can be guided more easily.
In the display device according to the present invention, the first engaging portion 112 may be formed as a groove or hole instead of a hook. Accordingly, the body 10 can be more tightly coupled to the bracket 20. Since the second engaging portion 114 is only inserted into the first engaging portion 112, the body 10 and the bracket 20 can be joined more easily than when the hook is configured.
Referring to FIG. 45, a circular cable 163 may be laterally connected to the housing connector 523 of the display device according to the present invention. One end of the circular cable 163 may be connected to the housing connector 523 and the other end may be connected to the housing 500. Thus, the circular cable 163 can exchange electrical signals between the source PCB and the timing controller board within the housing 500.
In the display device according to the present invention, the circular cable 163 is connected to the side surface of the bracket 20 and can not be seen by the user. Further, since the housing 500 and the bracket 20 are connected to each other through the circular cable 163, the appearance can be cleaner.
Referring to FIG. 46, the display device according to the present invention may further include an electric wiring 816 penetrating the inside of the mounting surface 700. In this case, the FFC 161 may be connected to a portion where the FFC 161 is coupled to the electric wiring 816 without being connected to the edge of the bracket 20. The bracket 20 may be penetrated to connect the portion where the housing connector 523 is located with the electric wiring 816.
The electric wiring 816 can be inserted into the penetrated portion of the attached surface 700. The electric wiring 816 may be connected to the housing connector 523 on one side and to the circular cable 163 on the other side. Since the electric wiring 816 is located inside the attached surface 700, the electric wiring 816 may not be visible to the user.
The display device according to the present invention can be viewed as if the housing 500 and the bracket 20 are not directly connected using the electric wiring 816 inserted inside the attached surface 700. [ Accordingly, the user can feel that the appearance is cleaner and can concentrate on the display screen.
The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
