The back cover 200 may be provided on the rear surface of the display panel 100 . The back cover 200 may be directly attached to the display panel 100 . The back cover 200 may support the rear surface of the display panel 100 . That is, the back cover 200 means that the rigidity of the display panel 100 can be reinforced. Accordingly, the back cover 200 may include a material that is lightweight and has high strength. For example, the back cover 200 may include aluminum.

At least a portion of the back cover 200 may have a thickness different from that of other portions in the vertical direction. That is, the back cover 200 may be formed. The thickness of other parts of the back cover 200 in the vertical direction may be greater than the thickness of the edge region of the back cover 200 . In addition, the protrusion 223 located in the center of the back cover 200 may have the same thickness as the edge area of the back cover 200 . When the protrusion 223 is combined with the attachment surface, the contact area between the head part 10 and the attachment surface can be widened. Accordingly, the bonding force between the head part 10 and the attachment surface can be strengthened.

In the display device according to the present invention, since the thickness of the back cover 200 is not constant, the rigidity of the back cover 200 can be improved.

The coupling part 166 may be located at the boundary of the edge area of the back cover 200 . The coupling part 166 may be located on at least one side of the back cover 200 .

Detailed shapes of the first and second coupling holes 271a and 271b will be described later.

The head portion 10 of the display device according to the present invention may support the display panel 100 only with the back cover 200 . That is, the head part 10 may not have other covers other than the back cover 200 located thereon. Accordingly, the user can feel that the thickness of the head unit 10 has become very thin, and can focus 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 emission layer 130 and a lower electrode 140 . The transparent substrate 110 , the upper electrode 120 , the organic emission layer 130 and the lower electrode 140 may be sequentially formed.

However, it is not limited thereto, and the lower electrode 140 may include a transparent material (eg, ITO, etc.). In this case, light may be emitted to one side 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 be emitted to the outside. In this case, a light shielding plate may be further formed behind the lower electrode 140 to emit light emitted from the lower electrode 140 to the front side.

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, since the response speed of an OLED display device is 1000 times faster than that of a liquid crystal display device, there may be no afterimage left when displaying an image.

Referring to FIG. 4 , in the display device according to the present invention, the display panel 100 and the back cover 200 may be attached through an adhesive sheet 350 . The adhesive sheet 350 may include a double-sided tape capable of bonding both sides.

The adhesive sheet 350 may have a separate thickness. Accordingly, foreign substances or dust may enter between the display panel 100 and the back cover 200 . To prevent this, as shown in (a) of FIG. 4 , at least one side of the adhesive sheet 350 may be side-sealed with the sealing member 183 . The sealing member 183 may simultaneously shield the adhesive sheet 350 and at least one side of the display panel 100 .

As another example, as shown in (b) of FIG. 4 , a frame 187 may be inserted into at least one side of the adhesive sheet 350 . The frame 187 may contact at least one side of the adhesive sheet 350 and may be bent such that one end extends toward the display panel 100 . Accordingly, at least one side of the display panel 100 may be simultaneously shielded.

As another example, as shown in (c) of FIG. 4 , a middle cabinet 193 may be positioned between the display panel 100 and the back cover 200 . The middle cabinet 193 may guide a position where the display panel 100 is coupled. In the middle cabinet 193 , the flange 193a may be inserted between the display panel 100 and the back cover 200 . The body of the middle cabinet 193 may simultaneously shield at least one side of the display panel 100 and the back cover 200 .

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 have to be positioned entirely on the display panel 100, the amount of the adhesive sheet 350 required when manufacturing the display device can be reduced.

As another example, as shown in (d) of FIG. 4 , an edge portion of the back cover 200 may be bent toward the display panel 100 . Since the edge portion of the back cover 200 is bent, at least one side of the adhesive sheet 350 may be shielded from the outside.

In this case, other materials may not be included between the display panel 100 and the back cover 200 . Accordingly, the manufacturing process of the display device can be simplified and costs can be saved. In addition, the edge of the back cover 200 may be spaced apart from the adhesive sheet 350 . Accordingly, since the adhesive sheet 350 does not have to be positioned entirely on the display panel 100, the amount of the adhesive sheet 350 required when manufacturing the display device can be reduced.

In embodiments to be described later, structures located on the side of the adhesive sheet 350 are omitted for convenience of description. Structures located on the side of the adhesive sheet 350 are also applicable to other embodiments.

Referring to FIG. 5 , the display device according to the present invention may include a housing 500 electrically connected to the head unit. At least one PCB may be located inside the housing 500 . Each PCB may be spaced apart from each other.

For example, at least one PCB may be the main board 109 . The main board 109 may provide an interface for operating the display device. In addition, the main board 109 can check and manage the operating state of each part of the display device to make it an optimal state.

The power supply 107 can convert an AC frequency to a DC frequency. That is, the power supply 107 may change a low frequency to a high frequency to increase electrical efficiency.

As another example, at least one PCB may be the timing controller board 105 . The timing controller board 105 may transfer input signals to the display panel 10 . That is, the timing controller board 105 can transfer the timing signals CLK, LOAD, and SPi that control the source PCB and the video signals R, G, and B to the source PCB. Also, the timing controller board 105 may control images. The timing controller board 105 may be connected to the source PCB through any one of a flat cable, a circular cable, and wireless transmission.

As shown in (a) of FIG. 5, the main board 109 may be spaced apart from each other on the center and right side of the housing 500, and the power supply 107 is located on the right side of the main board 109 and the housing Based on the center of the housing 500, they may be positioned facing each other in the long axis direction (for example) of the housing 500.

The timing controller board 105 may be located on top surfaces 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 T-Con shield may be attached to a position where the timing controller board 105 is mounted to block 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 on the T-CON shield instead of the power supply 107 and the main board 109 . Accordingly, the power supply 107, the main board 109, and the timing controller board 105 may not interfere with each other. In addition, the T-Con shield may protect the timing controller board 105 from impact.

The timing controller board 105 may overlap 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 coupled with the power supply 107 and the main board 109 .

Alternatively, as shown in (b) of FIG. 5 , 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 may be positioned facing each other in the direction of the long axis of the main board 109 and the housing 500 .

In the display device according to the present invention, since the timing controller board 105 is located above the power supply 107 and the main board 109, space can be saved. Accordingly, the user may feel that the overall size of the housing 500 is reduced and aesthetically improved.

Referring to FIG. 6 , in the display device according to the present invention, speakers 117 may be positioned on both sides of the front surface of the housing 500 . The speaker 117 may output and transmit sound to the user. Accordingly, it may be more efficient for the speaker 117 to be located in front of the housing 500 .

As shown in (a) of FIG. 6 , the speaker 117 may be mounted on the front side of the housing 500 while being spaced apart from at least one PCB mounted inside the housing 500 . Alternatively, as shown in (b) of FIG. 6 , the speaker 117 may be spaced apart from the outside of the housing 500 . Since the speaker 117 is located outside the housing 500, the user can position the speaker 117 at a position where sound can be well transmitted to the user. Speakers 117 may be located on both sides of the display device head unit 10 .

In the display device according to the present invention, the speaker 117 may be located on the front side of the housing 500 or on both sides of the exterior. Accordingly, the user can better receive the sound of the display device.

7 to 15 are views illustrating a display device according to an exemplary embodiment of the present invention.

Referring to FIG. 7 , in the display device according to the present invention, the housing 500 and the head unit 10 may be spaced apart from each other without contacting each other. That is, it means that the housing 500 may not be located in a portion where the display screen is displayed. Accordingly, the user can focus more on the display screen.

As shown in (a) of FIG. 7, the housing 500 is spaced apart from the head unit 10 and can wirelessly exchange electrical signals. In this case, the user may feel that the appearance is cleaner than when the housing 500 and the head part 10 are connected through a cable.

As shown in (b) of FIG. 7 , a wireless transmission board 131 may be located inside the housing 500 to exchange electrical signals wirelessly with the head unit 10 .

The wireless transmission board 131 may transmit at least one of audio data and video data from the housing 500 to the head unit 10 . For example, the wireless transmission board 131 may transmit a digital video data signal of 4k (3840x2160) resolution to the head unit 10 at 60 frames per second (fps).

The wireless transmission board 131 may convert at least one of voice data and video data into an RF signal and transmit the signal to the head unit 10 . For example, the wireless transmission board 131 may convert at least one of voice data and video data into a high frequency signal having a millimeter-unit wavelength. Accordingly, the wireless transmission board 131 exhibits a high transmission rate and has a very high attenuation ration in the air, thereby reducing interference between devices.

However, since the wireless transmission board 131 has a high attenuation rate, an obstacle is located between the wireless transmission board 131 and the head unit 10 or the wireless transmission board 131 and the wireless reception unit of the head unit 10 are in a straight line. If it is not located, the signal may not be properly transmitted.

Accordingly, the display device according to the present invention may adjust the location of the wireless transmission board 131 or the wireless receiver so that signals are smoothly transmitted.

Referring to FIG. 8 , in the display device according to the present invention, a support portion 151 may protrude from one side of the head portion 10 . The support part 151 may be a part where the wireless receiver 217 is mounted. The support portion 151 may protrude from the head portion 10 so as to be located at a portion corresponding to the location of the wireless transmission board of the housing.

The wireless receiver 217 may be a part that receives audio data or video data from the wireless transmission board. That is, the wireless receiver 217 may receive at least one of audio data and video data of the wireless transmission board as a high-frequency signal having a wavelength in millimeters.

As described above, if the wireless receiver 217 is not positioned in a straight line with the wireless transmission board, signals may not be transmitted properly. Accordingly, the position of the wireless receiving unit 217 may be formed to correspond to the position of the wireless transmission board.

As shown in FIG. 8A , the support part 151 may protrude from at least a part of the upper side of the head part 10 . And, as shown in FIG. 8B , the support part 151 may protrude from at least a part of the right side of the head part 10 . And, as shown in FIG. 8C , the support part 151 may protrude from at least a part of the left side of the head part 10 . And, as shown in FIG. 8D , the support part 151 may protrude from at least a part of the lower side of the head part 10 .

As shown in FIGS. 8A to 8D , the support part 151 may protrude from one side of the head part 10 according to the position of the housing. Although not shown, the support portion 151 may protrude from a plurality of sides of the head portion 10 . For example, the support part 151 may protrude from at least a part of the left side and the right side of the head part 10 . In this case, the wireless receiver 217 can smoothly transmit the radio signal to the wireless transmission board regardless of the position of the housing.

In the display device according to the present invention, the support part 151 may be located on at least one side of the head part 10 . Accordingly, since the location of the wireless receiver 217 and the housing are adjacent to each other, materials that hinder wireless signal transmission may be reduced.

Referring to FIG. 9 , the head unit 10 of the display device according to the present invention may be attached to the attachment surface 700 . As described in FIG. 2 , the head portion 10 may be coupled to the attachment surface 700 through a coupling hole ( 271 in FIG. 2 ) and a coupling portion ( 166 in FIG. 2 ). Accordingly, the head part 10 and the attachment surface 700 can be tightly coupled to each other. The user can be more immersed in the screen because the head part 10 and the wear surface 700 are in close contact with each other.

The support part 151 may be in any one of a first state located inside the head part 10 and a second state protruding on one side of the head part 10 .

The support part 151 may not protrude to the outside of the head part 10 in the first state. Accordingly, the user can feel clean because the protruding part of the head part 10 is not visible. The support part 151 may protrude on one side of the head part 10 in the second state. Accordingly, wireless transmission and reception between the head unit 10 and the housing can be smoothly performed.

As shown in (a) of FIG. 9 , in the first state, the support part 151 may be located inside the head part 10 . A communication button 327 may be located on at least one side of the head unit 10 . When the power of the display device is turned on, the user may touch and/or push the communication button 327 to improve wireless communication capability between the housing and the head unit 10 . When the communication button 327 is touched and/or pushed, the support unit 151 may change from the first state to the second state.

As shown in (b) of FIG. 9 , in the second state, the support part 151 may protrude on one side of the head part 10 . That is, the wireless receiver 217 mounted on the support 151 may be exposed to the outside. Accordingly, wireless communication between the head unit 10 and the housing can be facilitated.

In the display device according to the present invention, the state of the support part 151 may change as the user presses the communication button 327 located on the head part 10 . Accordingly, the user can protrude the support part 151 only when communication is not performed smoothly to maintain a clean appearance of the display device.

Referring to FIG. 10 , the support part 151 may be positioned to be spaced apart from the head part 10 . That is, the support part 151 may be of a dongle type.

The support part 151 may be connected to at least one electrical wire 161 or 163 . For example, the support unit 151 may transmit signals through the head unit 10 and an HDMI cable, and may receive power through the circular cable.

Accordingly, despite the movement of the housing 500, the housing 500 and the wireless receiver 217 are located on a straight line, so that wireless communication can be smooth.

In the display device according to the present invention, the protrusion angle of the support part 151 may change according to the position of the housing 500 . Accordingly, the positioning of the housing 500 and the wireless receiver 217 on a straight line can be maintained even without manual adjustment.

Referring to FIG. 14 , in the display device according to the present invention, power of the display device may first be turned on (S10). The display device may be powered on by a user using a remote controller or touching and/or pushing a power button.

After that, the wireless receiver may protrude on one side of the head (S20). In detail, the support unit protrudes on one side of the head unit, so that the wireless receiver mounted on the support unit can be exposed to the outside. The wireless receiver may automatically protrude when the power of the display device is turned on. In addition, the wireless receiver may protrude by touching and/or pushing a communication button after the power of the display device is turned on.

After that, RF pairing may be performed between the head unit and the housing (S30). In detail, RF pairing may be performed between the wireless receiving unit of the head unit and the wireless transmitting board of the housing. RF pairing refers to a state in which a communication connection is allowed between devices wirelessly communicating with an RF frequency. Mutual wireless communication may be possible only through an RF pairing process between the head unit and the housing.

In RF pairing, first, a wireless transmission board can search for a wireless receiver located nearby. After that, the wireless transmission board can bring product information from the searched wireless receiver. After that, the wireless transmitting board may request pairing to the wireless receiving unit so that pairing may proceed with each other.

Thereafter, the wireless transmission board may determine whether a line of sight (LOS) condition and a packet error rate (PER) tolerance criterion are satisfied during wireless communication (S40). A line of sight is a free space path between two points. That is, it means that the path between the radio receiver and the radio transmission board is on the line of sight. Accordingly, when there is an obstacle between the wireless receiving unit and the wireless transmitting board, the line-of-sight condition may not be satisfied.

The packet error rate refers to a rate at which video data or audio data transmitted wirelessly is not normally delivered. Accordingly, when the packet error rate is higher than a certain level, the display screen may be broken or audio may not be transmitted properly.

When the line of sight condition and the packet error rate do not satisfy the acceptance criterion, the support unit protruding from the head unit may be rotated at a predetermined angle from the front surface of the head unit (S50). In detail, as described with reference to FIG. 13 , the support may rotate so that the wireless receiver is located on a straight line according to the position of the housing. The support unit may be rotated until the line-of-sight condition and the packet error rate satisfy acceptable standards, so that the housing and the wireless receiver are placed on a straight line.

The display device according to the present invention may adjust the position of the wireless receiver until communication between the wireless receiver and the wireless transmission board satisfies a predetermined condition. Accordingly, the display device can smoothly perform wireless communication.
