[0009] <<Overall Configuration of Display Device>> FIG. 1 is a perspective view showing an example of the appearance of a display device according to an embodiment of the present technology.

[0010] 1 is composed of a display unit 11 and a stand unit 12. The display unit 1 is configured by fixing the rear surface of the display unit 11 to the stand unit 12. For example, the display unit 11 is detachable from the stand unit 12.

[0011] The display unit 11 has a thin display panel 21 made of an organic EL display. The display panel 21 may be made of another display device such as an LCD (Liquid Crystal Display). The display device 1 having the display panel 21 is used as an external display for a PC, a game console, or the like. A connection terminal such as an HDMI (registered trademark) is provided on the rear side of the display unit 11.

[0012] The stand 12 has a stand base 31, a support member 32, and an elevation unit 33. The stand 12 is configured by attaching the tip of the support member 32 to the center of the stand base 31, which is a circular, thin-plate-shaped base, and providing the elevation unit 33 above the rear end of the support member 32. The support member 32 is a member having a width narrower than the radius of the base and a predetermined thickness. The support member 32 and the elevation unit 33 may be formed integrally. At least a portion of the stand base 31 and the support member 32 is made of a strong, heavy material such as metal.

[0013] The external configuration of the display device 1 will be described in detail with reference to Figures 2 to 4. In Figures 2 to 4, the same components as those shown in Figure 1 are denoted by the same reference numerals. Duplicate descriptions will be omitted where appropriate.

[0014] 2A and 2B are a front view and a rear view, respectively, of the display device 1.

[0015] 2A, the display unit 11 having a horizontally long rectangular display panel 21 is fixed to the stand unit 12 so that a vertical axis passing through the center of the display unit 11 passes through the centers of the stand base 31, support member 32, and lifting unit 33. The support member 32 and lifting unit 33 have approximately the same width. A vertically long oval hole 33A is formed in a position near the bottom of the lifting unit 33. Hole 33A is used to pass a cable through and organize the wiring.

[0016] As shown in B of Fig. 2, a storage section 22 is provided in the approximate center of the rear side of the display panel 21. The storage section 22 is provided inward from the top, bottom, left, and right edges of the display panel 21. When viewed from the rear, the storage section 22 has a horizontally long oval shape with arc-shaped sides and a straight line on the top and bottom. The storage section 22 houses various components, such as a control board that controls the driving of the display panel 21 and a board that controls the power supply. An external power supply using a power adapter may be used without providing a board that controls the power supply.

[0017] A shallow, substantially square recess 22A is formed in the approximate center of storage section 22. Fixing section 35 of stand section 12, which serves as a fixing mechanism, is fitted into recess 22A, and display section 11 is fixed to stand section 12. In rear view, fixing section 35 has approximately the same shape as recess 22A.

[0018] An operation unit 23 including buttons and the like is provided at a position below the right side of the display panel 21. The operation unit 23 is used for operations such as switching inputs and adjusting image quality.

[0019] 3A and 3B are a left side view and a right side view, respectively, of the display device 1.

[0020] 3A and 3B, the upper surface of the support member 32 forms a slope that slopes downward toward the front. The length of the support member 32 is longer than the radius of the stand base 31. Because the length of the support member 32 is longer than the radius of the stand base 31, the rear end of the support member 32 is located behind (extends beyond) the rear end of the stand base 31. The rear end of the lifting unit 33, which is provided above the rear end of the support member 32, is also located behind the rear end of the stand base 31.

[0021] The lifting / lowering unit 33 is a columnar member with an arcuate back surface. The lifting / lowering unit 33 has a lifting mechanism. The vertical length of the lifting / lowering unit 33 is, for example, slightly shorter than the vertical length of the display panel 21. The lifting / lowering unit 33 is provided substantially vertically at the rear end of the support member 32. The support member 32 has an upper surface that slopes downward toward the front, so that the lifting / lowering unit 33 is in a floating state, and space is formed below the lifting / lowering unit 33.

[0022] A cylindrical tilt unit 34 is provided on the front side of the lift unit 33. The tilt unit 34 has a tilt mechanism. A fixing unit 35 used to fix the display unit 11 is provided in front of the tilt unit 34. The tilt unit 34 is provided between the lift unit 33 and the fixing unit 35, and can be raised and lowered integrally with the display unit 11 fixed to the fixing unit 35.

[0023] 4A and 4B are a plan view and a bottom view, respectively, of the display device 1. Except for a portion of the bottom side, a plurality of slits are formed in the peripheral side surface of the storage section 22 in parallel with the direction of the display panel 21. Terminals are provided together on the bottom surface of the storage section 22.

[0024] The display device 1 having the above-described external configuration has a swivel function, a tilt function, and a lift function. Each function will be described below.

[0025] <<Functions of the Display Device>> <Swivel Function> Figure 5 is a diagram illustrating the swivel function. As indicated by the outline arrow in Figure 5, the swivel function is a function for rotating the display unit 11 left and right. For example, by holding either the left or right edge of the display panel 21 and pulling it toward you or pushing it inward, the user can adjust the left-right orientation of the display unit 11.

[0026] When the user adjusts the orientation of the display unit 11, the stand base 31 remains fixed and the entire other components rotate, as shown in Fig. 6. Fig. 6A shows a state in which the display surface of the display panel 21 is oriented at a 45-degree angle to the left, and Fig. 6B shows a state in which the display surface of the display panel 21 is oriented at a 45-degree angle to the right. For example, the swivel angle can be adjusted within a range of 0 to 360 degrees.

[0027] FIG. 7 is an enlarged view of the vicinity of the swivel portion.

[0028] As shown by the dashed line in Fig. 7, the connecting portion of the tip of the support member 32 with the stand base 31 becomes a swivel portion 32A that realizes the swivel function. The tip of the support member 32 is formed in a substantially semicircular shape. Fig. 7A shows an enlarged view of the vicinity of the swivel portion 32A in the state shown in Fig. 6A, and Fig. 7B shows an enlarged view of the vicinity of the swivel portion 32A in the state shown in Fig. 6B.

[0029] Here, in the display device 1, the weight balance of each component is adjusted so that the center of gravity of the set (the entire display device 1) is located on the swivel axis.

[0030] 8 and 9 are diagrams schematically showing the center of gravity of the set.

[0031] 8A and 8B and 9 show the center of gravity positions in right side, bottom, and rear views, respectively. In each figure, the center of gravity position C when viewed from each direction is indicated by a small hatched circle.

[0032] As shown in Figures 8 and 9, the weight balance of the components of the display device 1 is adjusted so that the center of gravity C of the set is approximately on the swivel axis. The dashed-dotted line L indicates the rotation axis (swivel axis) of the swivel unit 32A. The center of gravity C is located inside the storage unit 22, in front of the tilt unit 34. The display unit 11 is fixed by the fixing unit 35 so that the storage unit 22, which is provided on the back surface of the display panel 21, is located on the swivel axis when the display surface of the display panel 21 is in a vertical position. Note that the center of gravity being located on the swivel axis also includes the center of gravity being located at a position with a design or manufacturing error from the swivel axis. The center of gravity being located on the swivel axis also includes the center of gravity being located approximately on the swivel axis.

[0033] Since the center of gravity of the set is located on the swivel axis, the center of gravity does not move during swivel operation. The circular shape of the stand base 31 also makes it possible to maintain the required tilt angle as shown in FIG. 10 regardless of the swivel angle. FIG. 10 shows a cross section of the display device 1 with some parts omitted. The triangular range #1 in FIG. 10 indicates the tilt angle range in a side view. The size of the stand base 31 is designed so that, when the display unit 11 is at its highest position, the required tilt angle can be maintained regardless of the swivel angle.

[0034] <Tilt Function> Fig. 11 is a diagram illustrating the tilt function. The tilt function is a function for tilting the display surface of the display unit 11 up or down. For example, by holding either the top or bottom edge of the display panel 21 and pulling it toward you or pushing it in, the user can adjust the orientation of the display unit 11 diagonally upward or downward.

[0035] When the user adjusts the orientation of the display unit 11, the orientation of the display surface of the display unit 11 changes around the rotation axis of the tilt unit 34, as shown in Fig. 11. Fig. 11A shows a state in which the tilt angle is 0 degrees (the display surface is vertical), and Fig. 11B shows a state in which the tilt angle is a predetermined angle. For example, the tilt angle can be adjusted within a range of 5 degrees forward tilt and 25 degrees backward tilt.

[0036] Here, the display device 1 employs a configuration in which the components of the display unit 11, such as the circuit board, are concentrated at the center of the back surface of the display unit 11, and the center of gravity of the display unit 11 is adjusted to be located approximately at the center of the display unit 11. As a result, the center of gravity of the display unit 11 is located close to the tilt axis. The tilt unit 34 is provided behind a fixing unit 35 that fixes the approximately center of the back surface of the display unit 11 (storage unit 22) (FIGS. 2 and 3).

[0037] FIG. 12 is a diagram showing an example of the center of gravity position during a tilt operation.

[0038] Center of gravity position C1 shown in A of Fig. 12 indicates the center of gravity position on the display unit 11 side when the tilt angle is 0 degrees. On the other hand, center of gravity position C2 shown in B of Fig. 12 indicates the center of gravity position on the display unit 11 side when the display unit 11 is tilted backward by a predetermined angle and the tilt angle is in the state shown in B of Fig. 11. As shown in Fig. 13, center of gravity position C1 and center of gravity position C2 are at approximately the same position in front of the tilt unit 34 and are near the rotation axis (tilt axis) of the tilt unit 34. Position P1 indicates the rotation axis of the tilt unit 34. Dashed circle #11 indicates the center of gravity trajectory during tilt operation.

[0039] In this way, by positioning the center of gravity of the display unit 11 close to the tilt axis, it is possible to minimize the movement of the center of gravity during tilting. Furthermore, even when tilting is performed, it is possible to keep the center of gravity of the display unit 11 close to the swivel axis. In Figures 12 and 13, the center of gravity of the display unit 11 is shown at approximately the same position as the center of gravity of the set described with reference to Figure 8 etc., but in reality, these center of gravity positions are slightly shifted due to the weight balance of the parts, etc.

[0040] <Lifting Function> Fig. 14 is a diagram illustrating the lifting function. The lifting function is a function for moving the display unit 11 up and down. For example, the user can adjust the height of the display unit 11 by holding the left and right edges of the display panel 21 and lifting or lowering it.

[0041] When the user adjusts the height of the display unit 11, the height of the display unit 11 changes as shown in Fig. 14. Fig. 14A shows the state in which the height of the display unit 11 is at its highest, and Fig. 14B shows the state in which the height of the display unit 11 is at its lowest.

[0042] In the display device 1, the lifting unit 33 is provided substantially vertically so that the lifting direction of the display unit 11 is substantially vertical. By making the lifting direction of the display unit 11 substantially vertical, it is possible to keep the center of gravity of the set substantially on the swivel axis even when the height is adjusted.

[0043] FIG. 15 is a diagram showing an example of the center of gravity position of the set during lifting and lowering operations.

[0044] The left side of Fig. 15 shows the position of the center of gravity of the set when the display unit 11 is at the highest position. On the other hand, the right side of Fig. 15 shows the position of the center of gravity of the set when the display unit 11 is at the lowest position. Even if the height of the display unit 11 changes, as shown by the arrow, the position of the center of gravity of the set is located on the swivel axis. In Fig. 15, the position of the center of gravity of the set when the height of the display unit 11 changes is shown at the same position within the storage unit 22, but in reality it is at a slightly different position.

[0045] The size of the stand base 31 is designed so that it can maintain a predetermined tilt angle regardless of the swivel angle when the display unit 11 is at its highest position. This makes it possible to always maintain the required tilt angle regardless of the height of the display unit 11.

[0046] Furthermore, by providing the lifting unit 33 at the rear end of the support member 32 and shifting the center position of the stand base 31 and the position of the lifting unit 33 as shown by the arrow in Fig. 16, it is possible to avoid unnecessary expansion of the size of the stand base 31. The two-dot chain line L11 in Fig. 16 indicates the lifting axis.

[0047] That is, by using the support member 32 to lift the lower part and providing the lifting unit 33 so that a part of it protrudes rearward from the rear end of the stand base 31, it is possible to reduce the size of the stand base compared to when the lifting unit is provided directly on the upper surface of the stand base. If the lifting unit were provided directly on the upper surface of the stand base, it would be necessary to provide the stand base in the range indicated by oval #21 in Figure 16, but such a large stand base is not necessary.

[0048] Since the lower part of the lifting section 33 is floating, the stand base 31 can be swiveled even when a keyboard or the like is placed near the stand base 31.

[0049] As described above, by ensuring that the center of gravity of the set is always on the swivel axis even when adjustments are made using the swivel function, tilt function, and lift function, it is possible to prevent the size of the base of the stand from increasing.

[0050] <<Modifications>> The storage section 22 may be provided over the entire back surface of the display panel 21. Although the storage section 22 has an oval shape in rear view, it may have other shapes. In other words, the size and shape of the storage section 22 can be changed as desired, as long as the center of gravity of the display unit 11 is located approximately in the center of the display unit 11 by adjusting the weight balance of the components provided inside.

[0051] Although the support member 32 is provided so that its upper surface is a downwardly sloping surface, the support member 32 may be provided so that its upper surface is a substantially horizontal plane. In this case, too, a swivel portion 32A is provided at the tip of the support member 32, and the swivel portion 32A is connected to the stand base 31. In addition, a lifting portion 33 is provided above the rear end of the support member 32.

[0052] Although the stand base 31 has been described as having a circular shape, it may have any other shape, such as a square, as long as the size satisfies the tipping angle regardless of the swivel angle.

[0053] A pivot mechanism may be provided in the tilt portion 34 or the like.

[0054] The effects described in this specification are merely examples and are not intended to be limiting, and other effects may also be present. The embodiments of the present technology are not limited to the above-described embodiments, and various modifications are possible within the scope of the gist of the present technology.
