For example, the display device 300 is divided into an image processing device such as a set-top box for receiving broadcast signals or contents according to various network services, and a content playback device for playing content input from the image processing device. It can be implemented.

In this case, the method of operating a display device according to an embodiment of the present invention, which will be described below, includes not only the display device 300 as described with reference to FIG. 1, but also the image processing device such as the separated set-top box or the display unit 200. ) and a content playback device having an audio output module 385.

The above detailed description should not be construed as restrictive in any respect and should be considered illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.

The display device 300 can be broadly divided into a hand-held type that a user can hold in his hand and a mounted type that is mainly used at a specific location. The mounted display device 300 has a wall-mounted type in which the output unit is hung on a wall, or a stand type in which the output unit is combined with a stand 100 and placed on the floor.

In the case of the stand type, it is necessary to adjust the position or viewing direction of the output unit depending on the user's needs. To implement this, the output unit supports a structure capable of tilt behavior in the vertical direction of the stand 100, swivel behavior that can rotate in a direction parallel to the horizontal floor surface, and height adjustment behavior that can adjust the height in the vertical direction from the floor surface. You can.

However, the structure for implementing such tilt behavior, swivel behavior, and height adjustment behavior inevitably occupies a large volume, increases weight, and increases costs due to additional parts.

Therefore, a display device 300 with a simple structure that implements the above behaviors while minimizing increase in volume and weight and also minimizing production costs is required.

2A and 2B are side views of the display device 300 related to the present invention. The stand 100 of the present invention includes a base portion 110 located on the floor, a link body 120 extending upward from the base portion 110, and a display portion at the upper end of the link body 120. (200) is combined. The angle of the link body 120 can be adjusted through the lower hinge portion 140 located between the link body 120 and the base portion 110.

When the user holds and moves the display unit 200 to adjust the vertical position of the display unit 200, the angle of the lower hinge unit 140 changes and the display unit 200 changes position in the vertical direction and moves forward and backward at the same time. The location also changes. When the display unit 200 is moved upward, the display unit 200 is simultaneously pushed toward the back, so the position of the base portion 110 must be changed so that the display unit 200 moves toward the front again.

In order to solve this problem, the present invention places a gear part 130 between the base part 110 and the lower hinge part 140, so that when the lower hinge part 140 rotates, the lower hinge part 130 moves to the lower side through the gear part 130. The hinge portion 140 can move linearly in the front-back direction (first direction).

The lower hinge portion 140 is connected to the gear portion 130, and when the angle of the lower hinge portion 140 changes, the gear portion 130 rotates the lower hinge portion 140 so that the lower hinge portion 140 moves in a straight line. Converts movement to linear movement.

When the lower hinge unit 140 rotates in a direction where the angle with the floor surface increases by γ, the gear unit 130 moves the lower hinge unit 140 in the front direction by b to increase the angle that the link body 120 makes with the floor surface. As , changes, the change in the front-to-back position of the display unit 200 can be compensated for.

Figure 3 is a diagram showing the gear portion 130 of the stand 100 related to the present invention. The gear unit 130 includes a first gear that rotates around the rotation axis 142 of the lower hinge unit 140. The first gear rotates with the angle change of the link body 120, and the second pinion gear 132, which rotates in mesh with the first pinion gear 131, rotates in the opposite direction to the first pinion gear 131. It further includes a rack gear (133) meshed with the teeth of the second pinion gear (132). The rack gear 133 is located on the base portion 110, and when the position of the second pinion gear 132 on the rack gear changes, the positions of the lower hinge portion 140 and the link body 120 move forward and backward.

Figure 4 is a diagram showing the change in position of the lower hinge part 140 depending on the angle of the link body 120 in the gear part 130 of the stand 100 related to the present invention, from the state of Figure 2a to the state of Figure 2b. When the angle of the link body 120 changes, the first pinion gear 131 rotates clockwise and the second pinion gear 132 rotates counterclockwise. When the second pinion gear 132 rotates counterclockwise, the second pinion gear 132 moves forward on the rack gear 133.

Figure 5 is a view showing the base portion 110 of the stand 100 related to the present invention. The position of the lower hinge portion 140 changes on the base portion 110, and the lower hinge portion 140 is changed without exposing it to the outside. In order to accommodate the movement of 140, a sliding cover 135 may be further included as shown in FIG. 5. The sliding cover 135 covers the opening formed in the base cover 114 that covers the upper side of the base portion 110, and the lower hinge portion 140 passes through it. It moves on the base part 110 depending on the position of the lower hinge part 140, but if a sliding cover 135 of a larger size than the opening on the base cover 114 is used, the lower hinge part 140 moves as shown in FIG. 5. ) can be covered so that the gear unit 130 is not exposed to the outside, regardless of the position of the gear unit 130.

Referring to FIG. 3, the rack gear 133 of the gear unit 130 may be located on the sliding unit 170. The sliding unit 170 can be used when the user wishes to adjust the position of the display unit 200 in the front-to-back direction regardless of the vertical position of the display unit 200. It may include a slide guide 171 fixed to the base portion 110 and a slide plate 172 that moves forward and backward along the slide guide 171, and the rack gear 133 is located on the slide plate 172. It can be fixed.

The lower hinge portion 140 and the slide plate 172 are fixed to the base portion 110 so that the lower hinge portion 140 does not fall. FIG. 6 is a cross-sectional view taken along line A-A of FIG. 5, showing a fastener 175 penetrating the slide plate 172 and fixing the lower hinge portion 140. However, when the lower hinge portion 140 moves along the rack gear 133, the slide plate 172 does not move together, so the fastener 175 is located on the guide slot extending in the first direction on the slide plate 172. is fastened to and when the lower hinge portion 140 moves along the rack gear 133, the position of the fastener 175 on the guide slot 172a changes. A stopper 173 protruding from the base portion 110 may be further included to limit the moving distance of the slide plate 172.

The base portion 110 includes a base plate 111 in close contact with the bottom surface, and a base cover 114 that covers the upper surface of the base portion 110, and a lower hinge portion 140 on the base portion 110. It may include a rotating plate 112 that rotates about an axis perpendicular to the bottom surface. The rotating plate 112 is located on the upper surface of the fixed part, and the sliding part 170 and gear part 130 described above are located on the rotating part.

The rotating plate 112 has a disk shape, and a guide plate 113 is coupled to the fixed portion to couple the peripheral portion of the rotating plate 112 to the fixed portion. The circumference of the rotating plate 112 is sandwiched between the base plate 111 and the guide plate 113, and this structure can block movement in directions other than the rotation of the rotating plate 112.

7 and 8 are cross-sectional views showing the upper hinge of the stand 100 related to the present invention. Figure 7 is a vertical cross-section and Figure 8 is a horizontal cross-section. When the angle of the link body 120 changes and the angle between the link body 120 and the display unit 200 is constant, the vertical angle toward which the display unit 200 faces changes. For example, when the link body 120 rotates in a direction that increases the angle formed with the floor surface, and the angle formed by the link body 120 and the display unit 200 is the same, the display unit 200 rotates to face upward. A problem arises.

Therefore, in order to compensate for the angle of the display unit 200 according to the rotation of the link body 120, an upper hinge unit 150 located between the link body 120 and the display unit 200 may be further included. After adjusting the angle of the link body 120, the angle of the display unit 200 can be adjusted by adjusting the angle of the upper hinge unit 150. However, there is an inconvenience in that two adjustments are required to adjust the height of the display unit 200 upward. Accordingly, even if the angle of the link body 120 changes, the angle of the upper hinge part 150 can be linked to the change in the angle of the link body 120 so that the direction toward which the display unit 200 faces does not change.

The link body 120 includes a first link 121 and a second link 122 located inside the link cover 124. One end of the first link 121 is coupled to the rotation axis 155 of the upper hinge portion 150, and the other end is coupled to the center of the lower hinge portion 140. The second link 122 has one end pinned 154 to a point spaced a predetermined distance from the rotation axis 155 of the upper hinge unit 150, and the other end is spaced a predetermined distance from the rotation axis 142 of the lower hinge unit 140. Connect the pins (143) at the designated points.

As shown in FIG. 8, the upper hinge portion 150 includes a first upper hinge body 151, a second upper hinge body 152, and a first upper hinge body 151 and a second upper hinge body 152. and a hinge shaft 155 penetrating the first link 121. The second upper hinge body 152 faces the display unit 200 and may include a torsion spring 156 to support the weight of the display unit 200. The torsion spring 156 has both ends 156a of the coil spring extending laterally and has elasticity to keep the number of turns of the torsion spring 156 constant. The elasticity of the torsion spring 9156 can maintain the angle between the first upper hinge body 151 and the second upper hinge body 152 and support the weight of the display unit 200.

In addition, a ring-shaped friction washer 157 is interposed between the first upper hinge body 151 and the second upper hinge body 152 to provide friction between the two members to prevent the display unit 200 from moving when the user does not intend. can increase.

Figure 7(a) shows a case where the angle formed by the link body 120 and the bottom changes from α as shown in Figure 2a to β as shown in Figure 2b (link body ( When the angle formed by 120) with the floor surface changes by γ) the angle formed by the display unit 200 and the link body 120 also changes from α' to β'. That is, the angle change of the lower hinge part 140 is transmitted to the upper hinge part 150, and the upper hinge part 150 rotates in the opposite direction by the angle at which the lower hinge part rotates, so that the display part 200 always faces the same direction. It can be linked to do so.

The link body 120 includes a first link 121 coupled to the center of the lower hinge portion 140 and the center of the upper hinge portion 150, and in addition to the first link 121, one end of the lower hinge portion 140 ) includes a second link 122 that is pin-coupled at a position spaced a predetermined distance from the center of the link and the other end is pin-coupled at a position spaced a predetermined distance away from the center of the upper hinge portion 150.

2A and 2B, since the length L1 of the first link 121 and the length L2 of the second link 122 do not change, when the lower hinge part 140 rotates, the upper hinge part ( 150) also rotates in the opposite direction so that the angle formed with the link body 120 varies. Since the lower hinge portion 140 is fixed to the base portion 110, the position of the lower hinge portion 140 coupled to one end of the second link 122 does not change and the second link is positioned at the center of the lower hinge portion 140. The angle (θ) between the line extending to the pin 143 coupled with (122) and the bottom surface does not change. The line extending from the center of the upper hinge portion 150 to the pin 154 coupled to the second link 122 has the same angle with respect to the floor, and is ultimately connected to the display portion 200 of the upper hinge portion 150. The angle with the bottom surface of the hinge body 152 does not change and remains constant.

It may further include a link spring 123 for adjusting the vertical operating force between the first link 121 and the second link 122. When adjusting the angle of the upper hinge portion 150 by adjusting the tension of the link spring 123, torque fluctuation of the lower hinge portion 140 can be minimized.

Referring to FIG. 8, the upper hinge part is used to rotate the display unit 200 in the left and right directions in addition to the first upper hinge body 151 and the second upper hinge body 152 that rotate around the horizontal rotation axis 155. It may further include a third upper hinge body 153 that rotates around a vertically extending rotation axis 158. The third upper hinge body 153 is directly connected to the display unit 200, and since movement in the left and right directions is not related to gravity, it can have a simple structure omitting the washer 157 or torsion spring 156.

Figure 9 is a diagram showing the extended base portion 161 of the stand 100 related to the present invention. Since it is difficult to support the weight of the display unit 200 with only the size of the base unit 110 shown in FIG. 2A, an expanded base unit 161 may be further provided to expand the area of the base unit 110. The extended base portion 161 includes an open portion 161a on the upper side, so that the link body 120 extends upward, and the lower surface may include a material with high frictional force. The extended base portion 161 may include a heavy material in consideration of the weight of the display portion 200.

Figure 10 is a diagram showing the clamping part of the stand 100 related to the present invention.

The stand 100 can be supported using the clamping part 180, rather than using an expansion base obtained by extending the expansion base part 161 as shown in FIG. 9. The clamping part 180 occupies a smaller area than the expansion base 161, and has the advantage of preventing it from falling over because it has a structure that holds the top of a desk, etc.

In particular, when adjusting the position and angle of the display unit 200, it may fall if it is not fixed to the floor. However, by using the clamping unit 180, the position and angle of the display unit 200 can be adjusted more stably.

The clamping part 180 includes an upper clamping plate 181, a lower clamping plate 182, and a clamping adjustment screw 183 penetrating the lower clamping plate 182. The upper clamping plate 181 has an L-shape and is coupled to the rotating part 130 and includes an upper surface portion that is in contact with the upper surface of a top plate such as a desk or table, and a first side portion 181b that is bent from the upper surface portion and surrounds the side surface of the upper plate. . An opening 181c is formed in the upper surface 181a so that the base 110 of the stand 100 can be inserted and fixed.

The lower clamping plate 182 includes a lower surface portion 182a facing the upper surface portion 181a, and the lower surface portion 182a contacts the lower surface of the upper plate. The second side part 182b bent at the lower surface part 182a is fastened to the first side part 181b of the upper clamping plate 181, and a locking groove 182d is formed in the first side part 181b, and the second side part 182d is formed in the second side part 182b. A locking protrusion (181d) inserted into the locking groove (182d) may be formed at (182b). The locking groove 182d and the locking protrusion 181d are fastened as shown in FIG. 8b so that the top plate is positioned between the upper clamping plate 181 and the lower clamping plate 182 and can be fixed to the top plate.

A plurality of locking grooves 182d can be formed in the vertical direction and adjusted according to the thickness of the upper plate. However, since the locking groove 182d alone is insufficient to support the weight of the display unit 200, a clamping adjustment screw 183 may be further included. The clamping adjustment screw (183) penetrates the lower surface (182a) of the lower clamping plate (182) and when rotated, the clamping adjustment screw (183) moves through the lower surface (182a) and the clamping adjustment screw (183) moves on the lower surface of the upper plate (182). Fix the clamping part 180 by coming into close contact with it. The end of the clamping adjustment screw 183 may be widened as shown in FIG. 8B so that a large area contacts the lower surface of the upper plate.

As discussed above, according to at least one of the embodiments of the present invention, the range in which the position and angle of the display unit 200 can be adjusted is expanded compared to the prior art, making it easy for the user to adjust it to a convenient position and angle.

In addition, the stand 100 can be stably fixed to the top plate, so it can be stably fixed when adjusting the position angle of the display unit 200, and has the advantage of being mounted without taking up a large space.
