2. Description of the Related Art Generally, a desired mark attached to a product is a so-called brand mainly for identifying oneself and other products and for guaranteeing quality, and in most cases, the logo mark of each manufacturer is used. It is used, and the display position of the logo mark is selected at a position where the product is relatively conspicuous.

The display device is, for example, a personal computer or a television, and a typical example of the personal computer will be explained. As shown in FIG. 18, a display section 1, a keyboard 2, and The display unit 1 is composed of a mouse 3 and hardware 4 and is supported on a predetermined support 5.
The angle of the display surface can be freely adjusted in the front-back direction.

The display unit 1 of a personal computer has a screen 7 on the inside surrounded by a rectangular frame 6 as a whole, and a display body 8 such as a logo mark is almost always located at the lower center of the frame 6. Many are provided. Then, the line of sight of the worker, that is, the operator is the screen 7
The work is performed by shifting the line of sight of the area 7a at the substantially central portion from the front to the substantially vertical direction.

In this case, as shown in FIG. 19, the display body 8 such as a logo mark provided on the frame 6 has a positional relationship facing the operator 9 from the front side, and at least from the front side of the display section 1. At angle θ (30 degrees or more), even from a position that is vertically, horizontally or diagonally displaced,
For a third party 10 who can see the screen 7 of the display unit 1,
The display body 8 can be fully seen together with the screen 7.

As described above, as a maker, not only when the product is displayed in a store, but also when it is actually used, the quality is guaranteed, and at the same time, the logo is appealed to the user and a third party in the vicinity thereof. It is preferable that the display body 8 such as a mark is conspicuously provided at a position where the display unit 1 can be easily seen because it leads to an advertising effect.

In order to enhance the advertising effect, the display body 8 such as a logo mark is made conspicuous by increasing the contrast with the frame 6 or by attaching a three-dimensionally formed separate structure. ing.

[0008]

By the way, the operator 9 of the personal computer actually types characters and symbols while looking at the document or alternately looking at the screen 7 of the display unit 1 and the keyboard 2 to make a document. It creates graphics, programs, etc., and the line of sight moves constantly.

In this case, the display 8 such as a logo mark is provided in a conspicuous position and in a state where the contrast is increased, depending on the position of the lighting in the room where the work is performed, so that the degree of movement of the line of sight is increased. This causes the inconvenience that the conspicuous display body 8 enters the field of view and becomes obtrusive. In particular, when the illumination light is reflected, eyesight becomes serious, and there is a problem that work efficiency may be reduced or a work error may occur.

Therefore, in the conventional display device and display device, even if the display body is provided in a conspicuous position,
The problem to be solved is to prevent the operator from getting in the eyes of the operator, and to give a third party who looks around other than the operator a conspicuous display.

Reference numeral 4 denotes a product name, a company name, a design, etc., which will be hereinafter referred to as a logo mark or the like.

In this case, the base member 12 can be made of any suitable material such as paper, wood, plastic, metal, etc. For example, a casing or frame of a product corresponds to the base member 12. Recognized as something.

As shown in FIGS. 2 and 3, the display body 14 is formed of an assembly of thin linear pixels 14a, and each linear pixel 14a has a waveform forming the lenticular lens 13. The lens portion 13a is configured to be located in a valley portion (a portion corresponding to a boundary portion between adjacent wavy lens portions). Therefore, in the linear pixels 14a forming the display body 14, the width and pitch of the linear pixels 14a are determined in relation to the pitch in the waveform lens portion 13a of the lenticular lens 13 used.

Since the pixels 14a of the display body 14 are located at the valleys of the corrugated lens portion 13a of the lenticular lens 13 as described above, the display device 11 can be viewed from the front and in the front thereof. Even if the viewing position is shifted in the vertical direction, the pixel 14a is completely invisible, and the display body 14 such as a logo mark cannot be visually recognized.

However, when the display device 11 is viewed from the front by shifting it by an angle of about 30 degrees or more in the left-right direction, each pixel 14a located in the valley of the waveform lens portion 13a can be seen through the waveform lens portion 13a. As a result, the display body 14 such as the logo mark becomes the so-called lenticular lens 1.
It is visible through 3.

FIG. 4 shows a second embodiment relating to a display device.
~ 6. Display device 21 according to this embodiment
In the third embodiment, a base member 22 and an element having an optical structure for geometrically refracting light, for example, a lenticular lens 23 are provided, and the base member 22 has the same structure as that of the first embodiment. Similarly, a display body 24 such as a logo mark is displayed by a printing means or the like, and a lenticular lens 23 is superposed on the display body 24 and integrated. The base member 22 is substantially the same as that of the first embodiment, and the lenticular lens 2 is used.
The configuration of 3 is only slightly different, and the other configuration part, that is, the configuration of the display body 24 is also substantially the same as that of the first embodiment.

That is, the display body 2 according to the second embodiment.
4 is also formed of an aggregate of thin linear pixels 24a, as shown in FIGS. 5 and 6, and each linear pixel 24a is formed.
Is arranged so as to be located in a valley portion along the vertical direction in the corrugated lens portion 23a that constitutes the lenticular lens 23.

In the configuration of the lenticular lens 23 according to the second embodiment, a lens portion 23a having valleys in the vertical and horizontal directions is formed. The linear pixels 24a forming the display body 24 are formed along the vertical valleys, and the linear pixels 24a are linear in relation to the pitch in the waveform lens portion 23a of the lenticular lens 23 used. The width and the pitch of the pixel 24a are determined.

Since the pixels 24a of the display body 24 are positioned in the vertical valleys of the corrugated lens portion 23a of the lenticular lens 23 in this manner, the display device 21 can be seen from the front and the front thereof. Even if the viewing position in the state is vertically shifted, the pixel 24a is completely invisible, and the display body 24 such as a logo mark cannot be visually recognized.

However, when the display device 21 is viewed from the front by shifting it by an angle of about 30 degrees or more in the left-right direction,
Each pixel 24a located in the vertical valley of the wavy lens portion 23a becomes visible through the wavy lens portion 23a, and the display 24 such as a logo mark can be seen through the so-called lenticular lens 23.

The configuration of the lenticular lenses 13 and 23 used in the display devices 11 and 21 according to the above-described first and second embodiments is illustrated in which the lens portions 13a and 23a have a substantially arc shape. However, the present invention is not limited to this, and for example, the lens unit having the configuration shown in FIG. 7 may be used.

That is, the lens portions 13a and 23a of the lenticular lenses 13 and 23 are partitioned by the V-shaped groove portion 15, and the tops of the lens portions 13a and 23a are formed into a gentle arc-shaped curved surface. The linear pixels 14a and 24a forming the display bodies 14 and 24 such as logo marks printed on the base members 12 and 22 are the same and correspond to the valleys formed by the V-shaped groove portions 15. It is provided at the position where

By forming in this way, the light a passing through the lens portions 13a and 23a is also seen when viewed from the front.
Is condensed by each lens portion and the pixels 14a and 24a cannot be seen at all, but when viewed from the front by shifting by an angle of about 30 degrees or more in the left-right direction, light b from an oblique direction passing through the lens portions 13a and 23a. The light is condensed by each lens portion, but the pixels 14a and 24a provided in the valley portions become visible, and the display bodies 14 and 24 such as logo marks can be visually recognized.

In any case, by using an element having a geometrically refracting optical structure such as a lenticular lens as a display device, a display body such as a logo mark can be seen when viewed from the front side. The display is made invisible so that the display can be seen from a position where the angle is changed other than from the front.

Further, a third embodiment as a display device is shown in FIGS. The display device 31 according to the present embodiment utilizes a hologram effect, and is provided between the base member 32 and the cover film 33.
The photopolymer layer 34 is integrally laminated in a sandwich shape, and the photopolymer layer 34 constitutes a display body such as a logo mark.

The base member 32 is a base film coated with a so-called photographic sensitizer, and is mounted on a special image pickup device for holography to display a logo mark or the like, for example, with a laser beam. By utilizing the coherence of such coherent waves, the wavefront of the reflected wave (object wave) from the object is recorded, and the object wave and the reference wave called the reference wave are made to interfere with each other and the The shape is recorded on the photosensitive agent as the pixel 34a.

At the time of this recording, the recorded shape is made invisible when viewed from the front, and the recorded shape when viewed from the left and right side surfaces and the upper and lower surfaces at a predetermined angle from the front, or from an oblique direction. That is, the pixels 34a of the display body such as a three-dimensional logo mark may be made visible.

The display devices 11, 21 thus constructed are
31 is attached to a product having a display function, such as a personal computer. A display device equipped with the display device 11 will be described as an example.

A first embodiment of a display device, that is, a personal computer as a typical example is shown in FIGS.

The personal computer has a display unit 41.
, A keyboard 42, a mouse 43, and hardware 44. The display unit 41 is supported on a predetermined support base 45 via legs 45a, and the height and angle of the display surface are set in the front-back direction. It can be adjusted arbitrarily.

The display section 41 of the personal computer is
An inner side surrounded by a rectangular frame 46 as a whole is a screen 47, and the display device 11 is arranged in the lower central portion of the frame 46.

Regarding the arrangement of the display device 11 in this case, as shown in FIGS.
6, when the display device 11 is arranged in a state of slightly protruding from the surface, and when the display device 11 is provided in the frame 46.
Of the display device 11 on the frame 46 when it is arranged so as to be flush with the frame 46 in a state where the whole is embedded.
There is a case where half of the above is arranged in a buried state, and these arranged states can be selected appropriately. In short, it suffices if the display device 11 is arranged on the frame 46 so that the presence of the display device 11 can be visually recognized from the front side of the display unit 41 in the personal computer.

Then, as shown in FIG.
That is, the operator's line of sight is such that the work is performed in a direction in which the area 47a at the substantially central portion of the screen 47 is viewed substantially vertically from the front, as described in the conventional example, and when the display unit 41 is tilted. Even if there is, the line of sight turns to a state in which the screen 47 is slightly looked down, and the user sees the screen 47 substantially vertically.

In this state, the operator 49 looks at the document and displays the screen 4 of the display unit 41 as shown in FIG.
While looking at 7 and the keyboard 42 alternately, characters and symbols are typed in to create a document, a figure, a program, etc., and the line of sight is constantly moving. Of course, the line of sight is displayed each time. It will traverse the device 11.

However, since the display device 11 is formed so that the display body 14 such as the logo mark cannot be visually recognized when viewed from the front, there is no display that would be annoying to the operator 49 who is working. , Display device 1
The existence of 1 can only be seen as a simple frame that does not disturb the eyes. Therefore, the operator 49 can concentrate on the work without being caught by an obstacle.

In this state, the third person 50 around the operator other than the operator 49 makes a display from a position deviated in the left or right direction or an oblique direction at an angle θ (30 degrees or more) from the front of the display unit 41. The screen 47 of the section 41 can be seen, and at the same time, the display body 14 such as the logo mark on the display device 11 can be sufficiently seen together with the screen 47.

When a product such as a personal computer provided with the display device 11 having the above-mentioned structure is displayed in a store, the display 14 such as a logo mark cannot be visually recognized when standing in front of the product, When looking at the product diagonally from a distant position while looking, the display 14 such as the logo mark can be clearly seen, which not only hinders the search for a product of which quality is guaranteed. , When the user stands in front, the display of the logo, etc. disappears, which in turn arouse the customer's interest.

Further, as a display device, as shown in FIG. 15, there is, for example, a so-called "notebook personal computer" for portable use, in which a display portion 51 and a keyboard 52 are integrally connected via a hinge portion 55 so as to be openable and closable. The display section 51 can be maintained in an inclined state depending on the opening degree. The mouse 53 can be attached as appropriate.

In this notebook computer as well, the display section 51 has a screen 5 on the inner side surrounded by a rectangular frame 56 as a whole.
7, the display device 11 is arranged in the center of the lower part of the frame 56.

Even in such a notebook computer, the user can type in characters and symbols while looking at the document or alternately looking at the screen 57 and the keyboard 52 to write a document,
A figure or a program is created, and the line of sight moves constantly and crosses the display device 11. However, when the display device 11 is viewed from the front as described above, the display body 14 such as a logo mark is displayed. Since it is invisible, there is no annoying display and it can only be seen as a frame. Therefore, the user can concentrate on the work without getting caught in the eyesore.

However, when a third person around the user looks at the display portion 51 from the side, the display 57 such as the logo mark on the display device 11 can be sufficiently seen together with the screen 57. Of. Therefore, a third party can know at a glance which product the notebook computer is.

As a display device, there is a television, for example, as shown in FIG. Also in this television, the inside of the display unit 61, which is surrounded by a rectangular frame 66 as a whole, is a screen 67, and the display device 11 is arranged in the lower central portion of the frame 66.

In the case of a television, unlike a personal computer, the movement of the line of sight is mostly within the screen 67, and the movement is not so severe. However, with regard to televisions, we want to guarantee the quality of our products and the goodness of the screen to general users.
The display method such as the logo mark is relatively conspicuous.

Therefore, although the movement of the line of sight to watch the television is not so severe, the display body such as the logo mark may become more conspicuous due to the indoor lighting and the like, so that the screen is focused and viewed. Occasionally it can be annoying. However, by using the display device 11 in which the display body 14 such as the logo mark is not displayed when viewed from the front as in the present invention, it becomes possible to enjoy watching TV without obstruction. .

When a television provided with such a display device 11 is displayed as a product in a store, the display body 14 such as a logo mark cannot be visually recognized when standing in front of the product, but it is separated while searching for the product. When viewing the product from a diagonal position, the display 14 such as the logo mark can be clearly seen, which not only hinders the search for a product of which quality is guaranteed, but also in front of the product. When the user stands up, the display of the logo, etc. disappears, which in turn arouse the customer's interest.

In each of the embodiments relating to any of the display devices described above, an example in which the display device 11 is used as an example has been shown and described, but the same can be said when other display devices 21 and 31 are used. However, the description of the arrangement example of the display devices 21 and 31 will be omitted because it is redundant, and the display device 11 in the above description should be understood as the display devices 21 and 31, respectively.

Regarding the position of the display device 11,
Although the example of the lower center part of the frame in the display unit has been described, the present invention is not limited to this position, and for example, as shown by the phantom line in FIG. 17, the lower left and right positions of the frames 46, 56, 66 are shown. , The upper central portion and the left and right positions can be attached at appropriate positions.

In any case, in the present invention, the display body is provided at a conspicuous position of the product, but the display body is optically invisible when viewed from the front side. In particular, it is designed so as not to be annoying when the screen is viewed from the front side when attached to a display device.
