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.
The module cover 200 may have a coupling hole 271 on one side and the other side. For example, the module cover 200 may have a coupling hole 271 on the upper and lower sides thereof. Each of the coupling holes 271 can face each other with respect to the first direction at the center of the module cover 200. The coupling hole 271 can penetrate through the module cover 200. The coupling hole 271 may have a shape extending in the first direction.
The bracket 153 and the first engaging portion 137 may be positioned between the display panel 100 and the module cover 200. [ The first coupling portion 137 may include a magnetic material. The bracket 153 and the first engaging portion 137 may be located at portions corresponding to the engaging holes 271 of the module cover 200.
The bracket 153 may be in the form of a frame having an empty central portion. The bracket 153 can reinforce the rigidity of the coupling hole 271 of the module cover 200. Accordingly, the bracket 153 can be attached to the area around the coupling hole 271 on the front surface of the module cover 200. That is, the bracket 153 may be positioned in a peripheral area surrounding the engaging hole 271. The bracket 153 can help prevent cracking or breakage of the coupling hole 271 at the time of coupling. The bracket 153 may include a metal material or a rubber material to reinforce the rigidity of the coupling hole 271.
The first engaging portion 137 may be located at least a portion of a portion corresponding to the engaging hole 271 on the rear surface of the display panel 100. The first engaging portion 137 may be located at the center of the bracket 153. The first engaging portion 137 may be located at a portion surrounded by the bracket 153 and the engaging hole 271. However, the present invention is not limited thereto and the first engaging portion 137 may be separated from the bracket 153 and the engaging groove 271.
The first coupling portion 137 may include a first one side coupling portion 137a and a first other side coupling portion 137b. The first one side engaging portion 137a and the first other side engaging portion 137b may be spaced apart from each other. The spaced apart portion between the first one side engaging portion 137a and the first other side engaging portion 137b may be a portion into which a hook described later is inserted. The first one side engaging portion 137a is located on one side of the body 10 and the first other side engaging portion 137b is located on the other side opposite to the one side of the body 10 with respect to the second direction .
The first coupling portion 137 may include a magnetic material. The first coupling portion 137 may be attached to the rear surface of the display panel 100. The first coupling portion 137 may be coupled to the display panel 100 through a screw. However, the present invention is not limited thereto, and the first coupling portion 137 may be coupled to the display panel 100 through an adhesive.
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. For example, the PCB cover 400 may include a plastic material. 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. 3, 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 may be an OLED display device. Accordingly, a separate light source is not required, and the volume and weight of the display device 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. 4, the display panel 100 and the module cover 200 may be attached through the adhesive sheet 350. The adhesive sheet 350 may include a double-sided tape capable of joining both surfaces together.
The adhesive sheet 350 may have a different thickness. Accordingly, foreign matter or dust may enter between the display panel 100 and the module cover 200. To prevent this, as shown in Fig. 4 (a), the sealing member 183 can be side-sealed to at least one side of the adhesive sheet 350. [ The sealing member 183 can shield at least one side of the adhesive sheet 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 sheet 350, as shown in Fig. 4 (b). The frame 187 abuts at least one side of the adhesive sheet 350 and can 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. 4 (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 sheet 350. [ Accordingly, since the adhesive sheet 350 does not need to be entirely placed on the display panel 100, the amount of the adhesive sheet 350 necessary when the display device is manufactured can be reduced.
As another example, the edge portion of the module cover 200 may be bent toward the display panel 100, as shown in Fig. 4 (d). Since the edge portion of the module cover 200 is bent, at least one side of the adhesive sheet 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 sheet 350. Accordingly, since the adhesive sheet 350 does not need to be entirely placed on the display panel 100, the amount of the adhesive sheet 350 necessary when the display device is manufactured can be reduced.
In the following embodiments, the structures located on the sides of the adhesive sheet 350 are omitted for convenience of explanation. The structures located on the side surfaces of the adhesive sheet 350 are applicable to other embodiments.
Referring to FIG. 5, the display device may include a housing 500 electrically connected to the body 10.
The housing 500 may transmit at least one signal 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).
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. 5A, the housing 500 can be connected to the body 10 through a plurality of flat cables 161 having a flat shape. The flat cable 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 flat cable 161 is advantageous in cost compared to other cables.
As another example, as shown in FIG. 5 (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 by the plurality of flat cables 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. 5 (c), 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 through the flat cable 161 or the circular cable 163.
The display device may have the body 10 and the housing 500 separated 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. 6, the display device can exchange electric signals with the housing 500 through the electric wiring 816 passing through the inside of the attachment surface 700 to which the body 10 is attached. In this case, the source PCB of the body 10 can be connected to the electric wiring 816 on one side.
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 source PCB at one side and to the circular cable 163 at the other side. The electric wiring 816 is located inside the attached surface 700 and may not be visible to the user.
The display device can connect the body 10 and the housing 500 via the electric wiring 816 inserted inside the attached surface 700. [ Accordingly, the user can see that the housing 500 and the body 10 are not directly connected. Thus, the user may feel that the appearance is cleaner and can concentrate on the display screen.
Referring to FIG. 7, the display device may not include the PCB cover in the body 10. Accordingly, the body 10 may need a space in which the source PCB 172 can be located.
For example, as shown in FIG. 7 (a), the module cover 200 may be recessed inwardly at a portion corresponding to the source PCB 172. In this case, the module cover 200 may have a thinner portion corresponding to the source PCB 172. [ Since the thickness of the module cover 200 is not the same, the rigidity of the entire module cover can be improved.
The source PCB 172 can be positioned on the rear surface of the display panel 100 regardless of the thickness of the adhesive sheet 350 because the thickness of the module cover 200 at the portion where the source PCB 172 is located is thin.
As another example, as shown in FIG. 7 (b), the module cover 200 may have the same thickness as the corresponding portion of the source PCB 172. That is, the module cover 200 means that there is no depressed portion. In this case, the thickness of the adhesive sheet 350 in the third direction between the display panel 100 and the module cover 200 may be thicker than the thickness of the source PCB 172 in the third direction.
Since the thickness of the module cover 200 at the portion where the source PCB 172 is located is the same, the manufacturing process of the module cover 200 is simplified and the cost can be saved.
As shown in FIG. 7C, the source PCB 172 may transmit an electrical signal to the housing 500 through a FFC (Flat Flex Cable) 161. The source PCB 172 may be connected to the FFC 161 on the opposite side of the portion connected to the source COF 123. The FFC 161 may include a plurality of signal connection terminal pins and at least one ground terminal pin for connecting the source PCB 135 and the housing 500. The FFC 161 is advantageous in cost compared to other cables.
The display device may be positioned between the source PCB 172 and the display panel 100 and the space of the module cover 200. Accordingly, a through hole or a hole may not be required in the module cover 200. Therefore, the module cover 200 is not formed well and the rigidity can be improved.
Referring to FIG. 8, 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. That is, the power supply 107 can supply power to the body. 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 via either a flat cable, a circular cable, or wireless transmission.
8A, the main board 109 may be spaced apart from the center portion and the right side of the housing 500, and 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. 8 (b), 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 device can save space because the timing controller board 105 is located at the top of 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. 9, a speaker 117 may be positioned 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. [
9 (a), 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. As shown in FIG. Alternatively, as shown in FIG. 9 (b), the speaker 117 may be positioned 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 may be such that the speaker 117 is located on both sides of the front or outer side of the housing 500. Thus, the user can receive the sound of the display device more easily.
Referring to FIG. 10, an FPC board (Flexible Printed Circuit Board) 174 may be disposed on the source PCB 172. The FPC board 174 may be positioned on the rear surface of the display panel 100. The FPC board 174 may be connected to the source PCB 172 via a connector 157. The connector 157 located on the source PCB 172 can connect the source PCB 172 and the lower end of the FPC board 174. [
The source PCB 172 may transmit electrical signals to the housing via the flat cable 161. have. The flat cable 161 may include a plurality of signal connection terminal pins and at least one ground terminal pin for connecting the source PCB 135 and the housing. The flat cable 161 is advantageous in cost compared to other cables.
As shown in FIG. 10A, the FPC board 174 may be located at the center of the display panel 100. The FPC board 174 may be connected to the flat cable 161 through a connector 157 located therein. Since the FPC board 174 is located at the center of the display panel 100, the flat cable 161 connected to the inside of the FPC board 174 can also be located at the center of the display panel 100.
Various driving ICs may be mounted on the FPC board 174. [ The driving IC can transmit and receive data between the source PCB and the housing. For example, the driving IC may be a SERDES (serializer / deserializer) IC. The SERDES IC can convert serial data / parallel data in and out of the chip into parallel data / serial data. As a result, the SERDES IC can speed up signal transmission.
As shown in FIG. 10 (b), the FPC board 174 may be located on one side of the display panel 100. Accordingly, the flat cable 161 connected to the FPC board 174 can also be positioned on one side of the display panel 100. The user can concentrate on the screen when the flat cable 161 is positioned on one side of the display panel 100 and enjoys the display screen.
Further, in the present embodiment, the FPC board 174 may protrude from the display device 100 on one side. That is, it means that one side of the FPC board 174 can be exposed. As a result, the flat cable 161 can be easily separated and coupled to the protruding portion of the FPC 174.
In this embodiment, the driving IC may be mounted on the source PCB 172. [ Accordingly, the FPC board 174 can save space because the driving IC is not mounted.
The display device may be connected to the flat cable 161 through the FPC board 174. [ Accordingly, the driving IC mounted on the FPC board 174 can transmit and receive data faster and more.
Referring to FIG. 11, the display device can be coupled to the attached surface 700 of the body 10. That is, the body 10 may be in one of a first state coupled with the attached surface 700 and a second state separated from the attached surface 700. The attaching portion may be formed to attach the body 10 to the attached surface 700. [ The attachment portion may include a hook 187 and a second engagement portion 157, which will be described later. The hook 187 of the attachment portion and the second engagement portion 157 can be formed in various ways. For example, the hook 187 may be attached to a first area of the attached surface 700 and the second engaging portion 157 may be attached to a second area of the attached surface 700.
11 (a), the attached surface 700 has a second engaging portion 157 and a hook 187 on its upper side and a second engaging portion 157 on its lower side have.
The second engaging portion 157 or the hook 187 positioned on the upper side and the lower side of the attached surface 700 may be located at a portion corresponding to the engaging hole 271 of the body 10 in the first state. A hook 187 may be positioned at the center of the upper surface of the attachment surface 700 and a second engagement portion 157 may be positioned at both sides of the hook 187. The second engaging portion 157 may include a second one side engaging portion 157a located on one side of the hook 187 and a second other side engaging portion 157b located on the other side facing the one side . The hook 187 and the second side and the other side engaging portions 157a and 157b may be spaced apart from each other.
11 (b), the hook 187 may be inserted into the coupling hole 271 located at the upper portion of the back cover 200 in the first state. The hook 187 can be brought into contact with the bracket 153 on the upper side of the engaging hole 271. The bracket 153 can prevent a crack from being formed in the back cover 200 around the coupling hole 271. Accordingly, the bracket 153 can reinforce the rigidity of the end of the coupling hole 271.
As shown in FIG. 11 (c), in the first state, the back cover 200 may have the first engaging portion 137 and the second engaging portion 157 attached to each other. In this case, the first coupling portion 137 and the second coupling portion 157 may have different polarities. The second engaging portion 157 may be inserted into the engaging hole 271 and attached to the first engaging portion 137. Accordingly, the second engaging portion 157 can be engaged with the engaging hole 271 like the hook 187 as well as by the magnetic attraction.
The display device according to the present invention can support the body 10 with the hook 187. Accordingly, the coupling force between the body 10 and the attached surface 700 can be compensated for by the second engagement portion 157 only.
