Abstract

Conventional display devices with stereo viewers have required time and trouble in switching between two-dimensional (conventional) display and three-dimensional (stereoscopic) display, and have also lacked portability, given the difficulty in reducing the thickness of the stereo viewer component. Provided is a detachable stereo viewer comprising a binocular lens (2), an arm (1), a partition (3), and a support means (4). The binocular lens and the arm are joined with a first rotational axle (5). The arm and the partition are joined with a second rotational axle (6) that is orthogonal to the first rotational axle. When the partition and the arm are vertical, it is possible to attach the stereo viewer to the display device by clamping the display device with the lateral face of the partition and the support means. It is possible to collapse the partition and the binocular lens of the stereo viewer with the first rotational axle and the second rotational axle. The stereo viewer is thus made detachable, simplifying switching between the three-dimensional display and the two-dimensional display and also improving the portability of the stereo viewer.

Description

Stereo viewer and display device

The present invention relates to a display device used in a thin mobile phone, a portable terminal or an electronic device, a stereo viewer capable of stereoscopic display, and a display device.

As one of the 3D (three-dimensional) display methods, a stereo viewer that displays 3D images by viewing the side-by-side stereo image in which the left image of the left viewing line and the right image of the right viewing line are arranged side by side There is a method used.

This method can reproduce a realistic 3D image using a small display element. (For example, Patent Documents 1 and 2)
FIGS. 11 (a) to 11 (c) are three-dimensional (3D) photo reproduction devices using a conventional stereo viewer.

As shown in FIG. 11 (a), in one of the conventional three-dimensional (3D) photo reproducing apparatuses, a stereo picture 145 is disposed in accordance with the

picture frame

146, and 2 is disposed at a distance from the position of the stereo picture 145. Three-dimensional display is enabled by viewing the left and right images with the left and right eyes through the binocular lens 102 consisting of two convex lenses 144.

As shown in FIGS. 11 (b) and 11 (c), in this conventional three-dimensional (3D) photo reproduction apparatus, the arm plate 101 and the binocular lens 102 with respect to the photo frame 146 are provided by two pivot shafts 147. It has a foldable structure by pivoting in the directions of arrows A and B.

Further, there has been proposed a method of reproducing a stereo image displayed on a display element as a stereoscopic image by fixing an arm component with a binocular lens to a side surface of a display element (display) of an electronic device (for example, Patent Document 3).
As an example of this, FIGS. 12 (a) and 12 (b) show structural diagrams of other conventional examples. As shown in FIG. 12A, this three-dimensional (3D) photo reproducing apparatus has an arm structure attachable to an outer frame of an electronic device 208 having a display element 211 for displaying a left image 209 and a right image 210. doing. In other words, at the other end of the arm 248 to which the binocular lens 202 is attached at one end, it is fixed to the housing of the electronic device 208 using the screw 249.

In addition, a structure of a lens part that is detachable and foldable to a display element such as a portable terminal has been proposed. (For example, Patent Document 4)

Japan Registered Utility Model No. 3025841 Japan Real Fair 3-010489 Japanese Patent Application Laid-Open No. 2004-177431 Japanese Patent Laid-Open No. 2004-347823

If a stereo viewer having a folding function as described in Patent Document 1 and Patent Document 2 and having a thin profile can be fixed on a display element of an electronic device, a stereo viewer that is easy to carry can be realized, but it is suitable until now. Structure did not exist.

In addition, the electronic device 208 having the display element 211 for a three-dimensional (3D) image described in Patent Document 3 has a structure for fixing the arm 248 to a casing frame outside the display element 211. In order to fix the arm to the portable terminal, it is conceivable to use a fixing screw (symbol 249 in FIG. 12A) as described in Patent Document 3. However, when the fixing screw is used, the electronic device is strongly held between the arms, so that a large stress is applied to the display element of the electronic device. Therefore, in general, to apply the arm structure as described in Patent Document 3 to a portable terminal which is required to be miniaturized and whose housing frame is designed to be narrow, consideration is given not to apply this large stress. is necessary. Furthermore, in the arm structure as described in Patent Document 3, it takes time to fix and remove the arm 248. Furthermore, the arm structure as described in Patent Document 3 is inconvenient to carry the arm and the binocular lens component when the arm 248 is removed.

Patent Document 4 is not a stereo viewer, but has a structure in which a magnifying lens can be attached to and detached from a display element, and can be thinly folded.

Embodiment 1

In the following, the first embodiment will be described on the assumption that the stereo viewer is attached to the portable terminal device, but the same applies to the case where the stereo viewer is attached to a thin electronic device having a display element such as portable car navigation or television. It is.

Although the display screen is divided into two, left and right images are displayed on the respective screens, and a stereoscopic image is displayed through a binocular lens, the same image may be displayed instead of the left and right images. At this time, the screen of the display element can be enlarged and viewed by passing the binocular lens.

FIG. 1 is a schematic structural view (a) to (c) of the stereo viewer according to the first embodiment.

FIG. 1A shows a form of a stereo viewer when attached to a portable terminal.

FIG. 1 (b) shows the form of the stereo viewer in a state of being detached from the portable terminal and folded.

FIG. 1C shows a configuration diagram when the stereo viewer is attached to the portable terminal.

The stereo viewer comprises an arm 1, a binocular lens 2, a partition 3 and a support means 4.

The arm 1 and the binocular lens 2 are coupled by a first hinge having a first pivot axis 5, and the first angle between the arm 1 and the binocular lens 2 can be changed at least from 0 degree to 90 degrees.

The partition plate 3 and the arm 1 are coupled by a second hinge having a second pivot 6. The second angle between the arm 1 and the partition plate 3 can be changed at least from 0 degrees to 90 degrees.

As shown in FIG. 1 (a), this second pivoting axis 6 passes the center of the first hinge, ie, the center line between the two lenses of the binocular lens 2, and is approximately the same as the first pivoting axis 5. Vertically, the binocular lens 2 and the arm 1 can be supported so as to be vertical when the partition plate 3 is erected perpendicular to the arm surface 1A.

The supporting means 4 is connected by a third hinge having a third rotating shaft 7, and the third angle formed by the arm 1 and the supporting means 4 is variable at 0 degrees or more, and the first rotating shaft 5 and the third rotating shaft 7 are nearly parallel.

As shown in FIG. 1C, the stereo viewer is fixed to the housing 8 of the portable terminal in such a manner that the display element 11 is sandwiched between the support means 4 and the partition plate 3.

In addition, in this Embodiment 1, although the arm 1 and the support means 4 assume that it is plate shape, it may be rod-shaped, for example. A plate is desirable to be thin when folded.

FIG. 2 shows cross-sectional structures (a) to (e) for explaining the details of the method of attaching and detaching the stereo viewer.

FIGS. 3A and 3B show perspective structural views of the stereo viewer. FIG. 3C is a plan view of the stereo viewer.

FIG. 2 (b) shows a state in which the support means 4, the partition plate 3 and the binocular lens 2 are vertically erected with respect to the arm 1 from the folded state of FIG. 2 (a).

The partition plate 3 has a second side 13 on the side near the binocular lens 2 and has a first side 12 on the side near the support means 4. Both sides of the first side 12 and the second side 13 are perpendicular to the second rotation axis 6.

When the binocular lens 2 is in contact with the second side 13, the binocular lens 2 can hold the partition plate 3 perpendicularly to the arm 1.

Here, in order to make the angle of the binocular lens 2 and the arm 1 perpendicular, the structure is supported by the partition plate 3, but otherwise, means for setting the angle to the first hinge without using the partition plate 3 is used It does not matter.

As shown in FIG. 2C, the case 8 of the portable terminal is sandwiched in the gap 14 formed between the first side 12 of the partition plate 3 and the support means 4.

As shown in FIG. 2D, when the second side 13 of the partition plate 3 contacts the display surface of the display element 11, the display surfaces of the arm 1 and the display element 11 are held vertically. As a result, the binocular lens 2 and the display element 11 are disposed in parallel at a specific distance apart.

For example, as shown in FIG. 2 (e), a spring 15 is built in the third hinge of the support means 4 having the third pivot shaft 7, and the third angle formed by the support means 4 and the arm 1 is 0 degrees. The structure has a structure in which a force is applied in the direction (arrow C in the drawing). Therefore, a part of the support means 4 is in contact with the back surface of the casing 8 of the portable terminal to fix the casing 8 of the portable terminal.

In addition, although the case where the 1st side 12 and the 2nd side 13 of the partition plate 3 were perpendicular | vertical to the 2nd rotational axis 6 was described here, if these 1st side 12 and the 2nd side 13 are parallel, It is not necessary that one side 12 and the second side 13 be completely perpendicular to the second rotation axis 6. However, if it deviates largely from the vertical direction, the arm surface 1A (see FIG. 1A) of the stereo viewer tilts from the horizontal, and it becomes difficult to stably mount on the casing 8 of the portable terminal. Therefore, it is desirable that the first side 12 and the second side 13 of the partition plate 3 be perpendicular to the second rotation shaft 6.

Note that “perpendicular” described in the present embodiment means that the angle between certain parts is 90 degrees, but there may be a deviation of several degrees.

The distance between the binocular lens 2 and the display element 11 is determined by the length of the partition plate 3 in the direction along the second rotation axis 6. By setting the value slightly smaller than the focal length of the two convex lenses of the binocular lens 2, the user can magnify the display screen through the lens.

In addition, when a function to change the length A4 (see FIG. 3C) of the arm 1 or the partition plate 3 in the direction along the second rotation axis 6 is added, the binocular lens 2 is displayed according to the user's vision. It also becomes possible for the user to adjust the distance of the element 11 freely. In the present embodiment, the description of the specific structural example is omitted.

As shown in FIG. 3 (c), the first rotation shaft 5 for connecting the arm 1 and the binocular lens 2 and the second rotation shaft 6 for connecting the arm 1 and the partition plate 3 are vertical. When 3 is folded, the second side 13 overlaps the first pivot 5. As a result, when the partition plate 3 is erected perpendicular to the arm surface 1A, the binocular lens 2 and the arm 1 can be made perpendicular.

The first side 12 of the partition plate 3 is perpendicular to the second rotation shaft 6. When the partition plate 3 is folded, the first side 12 is parallel to the third pivot 7 and a gap 14 exists between the first side 12 and the third pivot 7.

The length A2 of the arm 1 along the first pivot axis 5 is the first pivot axis of the binocular lens 2 so that the binocular lens 2 does not protrude from the arm 1 when the binocular lens 2 is folded. Less than length A3 along 5 Hereinafter, the length A2 in the direction along the first rotation axis 5 of the arm 1 is referred to as an arm width A2.

In the state of being attached to the housing 8 of the portable terminal, the partition plate 3 is disposed at the boundary of the left and right screens of the display element 11, so that the partition plate 3 does not interfere with stereoscopic display. Rather, the left and right screens can be separated by the presence of the partition plate 3, which has the advantage of facilitating stereoscopic viewing.

Therefore, it is desirable that the length A1 of the first side 12 of the partition plate 3 has a length equivalent to the boundary between the left and right screens of the display element 11. However, when the length A1 of the first side 12 exceeds A2 / 2 which is a half of the arm width A2, the partition plate 3 protrudes from the arm width A2 when folded. Therefore, it is desirable that the length A1 of the first side 12 of the partition plate 3 be smaller than half the arm width A2.

With this structure, if the thickness of the housing 8 of the portable terminal is smaller than the gap 14, it is possible to easily mount the stereo viewer.

FIG. 3D shows a structural example in which the stereo viewer of FIG. 3A is further folded once more by further including a fourth rotation axis 16. Since this becomes compact, for example, as shown in FIG. 3E, the stereo viewer can be conveniently carried by fixing the stereo viewer to the back surface of the casing 8 of the portable terminal. For example, a magnet is used for fixing the portable terminal to the housing 8, but other fixing methods may be used.

FIG. 4 shows configuration diagrams (a) to (e) when a Fresnel lens is used as the binocular lens 2. By using the Fresnel lens, for example, the thickness of the Fresnel lens can be reduced to about 1 mm or less, and the stereo viewer can be thinned.

As shown in FIG. 4 (d), the binocular lens 2 has a Fresnel lens surface 17 and a flat surface 18 on which a Fresnel lens is formed. Preferably, the Fresnel lens surface 17 faces the side of the partition plate 3.

As shown in FIG. 4B, when the Fresnel lens surface 17 faces the side of the partition plate 3, an optical path OP shown by a dotted line crosses the flat surface 18 almost perpendicularly. Therefore, the image viewed through the binocular lens 2 is less likely to be distorted.

If the Fresnel lens surface 17 is disposed on the opposite side to the partition plate 3, as shown in FIG. 4C, the angle between the optical path OP and the flat surface 18 is not perpendicular, so refraction occurs and the image is distorted.

Since the Fresnel lens surface 17 is easily scratched, it is possible to prevent the scratching by superposing the transparent plate 19 on the Fresnel lens surface 17 as shown in FIG. 4 (d).

It is desirable that antireflective films be provided on both sides of the transparent plate 19. An air layer is required between the transparent plate 19 and the Fresnel lens surface 17, and as shown in FIG. 4D, it is preferable to fix the periphery with an adhesive 20 or the like.

Furthermore, in order to prevent damage to the display surface of the binocular lens 2 using the Fresnel lens and the display element 11, as shown in FIG. 4 (e), for example, the first side 12 and the second side 13 of the partition plate 3 An elastic material 21 such as rubber is provided. Thereby, it can prevent that the partition plate 3 damages the Fresnel lens and the display surface of the display element 11. Moreover, it can prevent that the partition plate 3 slips with respect to the Fresnel lens surface 17 and the display surface of the display element 11, and can also prevent the shift | offset | difference of mounting | wearing of a stereo viewer.

With the above configuration, it is possible to realize a foldable, thin and easy-to-carry stereo viewer.

Second Embodiment
FIG. 5 is a perspective view (a) and (b) of the stereo viewer according to the second embodiment. The basic structure and the like are the same as in the first embodiment, and the description thereof is omitted.

A different point from the first embodiment is the fixing method by the support means 4.

As shown in FIG. 5A, two or more screw holes 23 are opened in the support means 4, and the two screw holes 23 are located on the opposite side across the partition plate 3. It becomes possible to fix the back surface of the case 8 of the portable terminal by the screw 22 fixed to the screw hole 23.

The arm 1 has a stopper 24 at one end thereof so that the third angle between the support means 4 and the arm 1 does not exceed 90 degrees. The spring 15 required in the first embodiment is unnecessary.

A spring may be used instead of the screw 22.

Further, other fixing means for fixing the support means 4 and the back surface of the casing 8 of the portable terminal can be considered. For example, using a magnet or providing concave and convex portions on the surface of the support means 4 on the side of the partition plate 3 and the rear surface of the housing 8 of the portable terminal, position control and fixing are performed by fitting concave and convex portions. It does not matter.

Third Embodiment
Next, a stereo viewer of Embodiment 3 which can be further reduced in thickness than Embodiment 1 will be described.

In the first embodiment, when it is folded as shown in FIG. 3A, it becomes thicker by the thickness of the partition plate 3. Furthermore, as shown in FIG. 3 (d), when the sheet is to be folded smaller, the thickness of the partition plate 3 is increased by two and the partition plate 3 itself has a problem that the folding mechanism is complicated. Was.

FIG. 6 shows stereo viewer structures (a) to (d) of the third embodiment. The arm 61, the binocular lens 62, the partition plate 63, and the support means 64 are plate-like parts.

The stereo viewer according to the third embodiment includes an arm 61, a binocular lens 62, a partition plate 63, and a support means 64.

The arm 61 and the binocular lens 62 are coupled by a first hinge 65 having a first rotation axis, and the first angle formed by the arm 61 and the binocular lens 62 can be changed at least from 0 degrees to 90 degrees.

The partition plate 63 and the arm 61 are coupled by a second hinge 66 having a second pivot axis. The second angle formed by the arm 61 and the partition plate 63 can be changed at least from 0 degrees to 90 degrees.

The second pivot axis passes through the center of the first hinge 65, that is, the center line between the two lenses of the binocular lens 62, and is substantially perpendicular to the first pivot axis, and the partition plate 63 is placed on the arm surface 61A. When standing vertically, the binocular lens 62 and the arm 61 can be vertically supported.

The support means 64 is connected by a third hinge 67 having a third rotation axis, and the third angle formed between the arm 61 and the support means 64 is variable at 0 degrees or more, and the first rotation axis and the third rotation axis are It is almost parallel.

FIG. 6A is a perspective view in the case where the angle between the binocular lens 62 and the arm 61, the angle between the partition plate 63 and the arm 61, and the angle between the support means 64 and the arm 61 are all 180 degrees.

The arm 61 has a width half the length of the long side of the binocular lens 62, and the arm 61 and the binocular lens 62 are connected by the first hinge 65. The partition plate 63 has substantially the same width as the arm, and the arm 61 and the partition plate 63 are connected by the second hinge 66.

A major difference from the first embodiment is that by setting the width of the arm 61 to about half of the long side of the binocular lens 62, the arm 61 and the partition plate 63 do not overlap. This enables thinning.

Furthermore, the central portion of the binocular lens 62 has a recess 68. A protrusion 69 is provided at one corner near the binocular lens 62 of the partition plate 63.

As shown in FIGS. 6C and 6D, after the binocular lens 62 and the partition plate 63 are rotated 90 degrees around the first hinge 65 and the second hinge 66 with respect to the arm 61, the recess 68 and the protrusion are obtained. By fitting 69, the binocular lens 62 and the partition plate 63 are fixed vertically to the arm 61.

The first hinge 65 and the second hinge 66 do not require complicated fixing functions.

FIG. 7 shows structural diagrams (a) and (b) when the stereo viewer shown in FIG. 6 is fixed to the casing 8 of the portable terminal.

FIG. 8 shows detailed structures (a) to (e) of the first hinge 65, the second hinge 66, and the third hinge 67.

The binocular lens 62 has a first side 86 in the longitudinal direction and a second side 87 parallel to the first side 86 and opposite to the first side 86, and the arm 61 is approximately half the length of the first side 86 of the binocular lens 62. And the fifth side 80 which is parallel to the fourth side 89 and the third side 88 perpendicular to the third side 88 and the third side 88 and perpendicular to the fourth side 89, and the partition plate 63 A sixth side 81 substantially half the length of the first side 86, a seventh side 82 perpendicular to the sixth side 81, and an eighth side 83 parallel to the sixth side 81 and perpendicular to the seventh side 82 Have.

The third side 88 and one half of the first side 86 are connected by a first hinge 65 having a first rotation axis, and the fourth side 89 and the seventh side 82 are a second hinge having a second rotation axis 66 are combined. The support means 64 and the fifth side 80 are connected by a third hinge 67 having a third pivot axis.
