Description

  The present invention relates to a display device that displays a desired shape (characters, numbers, etc.) by light emission. The display device of the present invention is used, for example, for vehicle decoration (for example, automobile scuff plate part decoration, vehicle interior ceiling decoration) and building decoration (for example, house nameplate decoration, ceiling decoration in a house or building).

  2. Description of the Related Art A scuff plate device for automobiles that has a decorative effect by displaying characters and the like in a light emitting manner has been put into practical use. An example of a conventional transmissive light-emitting scuff plate apparatus 100 is shown in FIG. In the scuff plate apparatus 100, a dial plate 101 (for example, an aluminum plate) in which a desired character or the like is punched is stacked on the light guide plate 102. White printing is applied to the back surface of the light guide plate 102. A light source 103 is disposed at a position facing the end face of the light guide plate 102. In such a scuff plate apparatus 100, when the light source 103 is turned on, light is introduced into the light guide plate 102 through the end face of the light guide plate 102. The introduced light is reflected on the back side of the light guide plate 102, thereby generating light in the upper surface direction of the light guide plate 102. As a result, light is emitted from the upper surface of the light guide plate 102. The emitted light reaches the dial plate 101, and a part of the light is extracted to the outside through a punched portion formed on the dial plate 101. With the above operation, a predetermined character or the like is lit and displayed. In addition to the above-described configuration, display devices with various ideas have been proposed (see, for example, Patent Documents 1 to 3).

JP 2002-279817 A Japanese Patent Laid-Open No. 2005-221661 JP 2006-062431 A

  In the conventional scuff plate device described above, a certain decoration effect can be obtained by emitting and displaying characters and the like. However, the decoration effect cannot be said to be sufficiently high because of the planar lighting. Moreover, it lacks luxury. Although it is possible to achieve a certain amount of stereoscopic effect by increasing the thickness of the dial, the limit is that a stereoscopic effect equivalent to the thickness of the dial can be obtained. Moreover, the light emission image obtained by making a dial thick is only a thing with a simple three-dimensional effect. Thus, a dramatic improvement in the decoration effect cannot be expected by thickening the dial. Further, since the thickness of the dial is directly linked to the thickness of the entire apparatus, there is a limit to increasing the thickness of the dial due to restrictions on the design of the apparatus.

In view of the above problems, the present invention provides a display device having the following configuration. That is, the present invention
A light emitting means for emitting light forward;
A sheet-like display that is disposed in front of the light-emitting means, receives a light from the light-emitting means, displays a desired shape (first shape) three-dimensionally, and transmits part of the light from the light-emitting means; ,
A translucent layer disposed in front of the sheet-like display,
Light control for displaying a desired shape (second shape) by controlling at least a part of the light transmitted through the sheet-like display body to change the mode of light emitted forward from the light-transmitting layer. Means,
It is a display apparatus provided with.

In the display device having the above configuration, the first sheet-like display body displays the desired shape (first shape) in three dimensions using the light of the light emitting means, and the light control means has the desired shape in the front (front direction). (Second shape) is displayed. In other words, the first shape is observed at a distance from the back of the second shape. The first shape and the second shape are objects to be compared with each other, thereby obtaining a high three-dimensional feeling or a sense of depth. In addition, by displaying the first shape in a three-dimensional manner, a design having a rich three-dimensional effect and elaborate design is constructed. As a result, spatial expansion can also be produced. Therefore, for example, when used for decoration such as a vehicle interior ceiling or a ceiling in a building, it is possible to give a sense of depth to the space or produce an open feeling.
On the other hand, since the three-dimensional feeling or the depth feeling is given based on the principle as described above, the thickness can be reduced.

(Light emission means)
In the present invention, display of the first shape by the sheet-like display body and display of the second shape by the light-transmitting layer and the light control means are performed using the light of the light emitting means.
The light emitting means preferably emits planar light. As a result, a display device having a large display area is obtained. A specific example of the light emitting means for emitting planar light is an organic EL element (electroluminescence). If an organic EL element is used, thickness reduction and reduction of power consumption can be achieved. The basic structure of the organic EL element is a structure in which a hole transport layer, a light emitting layer, and an electron transport layer are formed between a transparent electrode (anode) and a back electrode (cathode) (for example, JP-A-2002-124391). However, the present invention is not limited to those having such a structure, and organic EL elements having various structures can be applied to the present invention (for example, Japanese Patent Laid-Open Nos. 11-102166 and 2001-332389). No., JP-A No. 2004-111158, JP-A No. 2005-353504).
On the other hand, you may comprise a light emission means by a light source and the light guide which introduce | transduces the light of the said light source, and light-emits planar light. For example, an end surface of a plate-shaped light guide is an incident surface, and one of the side surfaces is a light emitting surface (outgoing surface). The side surface opposite to the light emitting surface is made light reflecting and diffusing by surface treatment or printing of a light reflecting and diffusing material. When light from a light source is introduced into such a light guide, planar light is emitted from the light emitting surface of the light guide. The light source may be embedded (in-mold) in the light guide. According to such a configuration, the light guide also functions as a waterproof member for the light source. It is also advantageous for downsizing. The material of the light guide is not particularly limited as long as it is light transmissive. The light guide is preferably made of a transparent material. Moreover, it is preferable to comprise a light guide with the material which is easy to process and excellent in durability. Specific examples of the light guide material include polycarbonate resin, acrylic resin (methacrylic resin (PMMA), etc.), epoxy resin, polyethylene terephthalate resin, and glass. Moreover, a well-known injection molding etc. can be employ | adopted as a processing method of a light guide.

The type of the light source is not particularly limited, but it is preferable to use an LED lamp because of its small size, low power consumption, long life, and the like. As the LED lamp, various types such as a bullet type and a chip type can be adopted. By using an LED lamp as a light source, there is an advantage that the amount of heat generated by the light source is reduced and the thermal influence on surrounding members is small.
The emission color of the light source used is not particularly limited. A plurality of light sources having different emission colors can be used in combination. When a plurality of light sources are used, it is possible to control the light emission state of each light source and emit light of various light emission modes. For example, if LEDs of red, green, and blue are used as light sources and the light emission state and light emission amount of each LED lamp are controlled, a desired color can be emitted. The number of LED lamps to be used can be determined by comprehensively considering the size of the light guide, the required luminance, and the like.

(Sheet display)
The sheet-like display body is disposed in front of the light emitting means (light emission direction). A translucent layer may be interposed between the light emitting means and the sheet-like display. Here, the light-transmitting layer can be composed of a light-transmitting body or air.
The sheet-like display body receives the light from the light emitting means and displays the desired shape (first shape) in three dimensions. Accordingly, in the present invention, the emitted first shape is stereoscopically viewed. On the other hand, the sheet-like display body transmits part of the light emitted from the light emitting means. The light that has passed through the sheet-like display is used for display of the second shape by the light-transmitting layer and the light control means.
The first shape is the desired character (any hiragana, katakana, kanji, alphabet, etc.), numbers (arithmetic numbers, kanji numerals), symbols (mathematical symbols, map symbols, etc.), figures (circles, triangles, squares, etc.) Or any combination thereof (hereinafter, these are collectively referred to as “characters”). As the first shape, a shape (pattern shape) in which specific characters or the like appear periodically may be employed.

As long as stereoscopic vision of a desired shape is possible, the configuration of the sheet-like display body is not limited. For example, a sheet-like display body that performs stereoscopic display using binocular parallax, such as a parallax barrier system, a lenticular lens system, a microlens system, or a holographic stereogram. The parallax barrier system is a system in which a plurality of parallax images cut in an up and down direction are alternately arranged, and a parallax barrier in which openings are formed at a fixed period is provided in front of the parallax barrier system. The lenticular lens method is a stereoscopic display method using a lenticular lens in which cylindrical lenses are arranged. There are two types of lenticular lens methods (layer depth and full depth), and either can be used. In the micro lens system, a micro lens array in which fine convex lenses are regularly arranged on one side is used. A parallax image (an image set so as to be stereoscopically displayed, also referred to as a stereoscopic image in this specification) is disposed behind each convex lens constituting the microlens array. In the microlens array system, stereoscopic vision using a mole phenomenon generated between a microlens and a stereoscopic image is obtained in addition to binocular parallax. The microlens array method does not choose the viewing direction, and there are few unpleasant flickering phenomena. Usually, a stereoscopic image is printed on the back surface of the microlens array. However, a layer on which a stereoscopic image is formed may be provided separately. In the microlens array system, a display in which an image appears to float (looks forward), a display in the opposite direction (sinks in the back), or a combination thereof can be arbitrarily set. In the present invention, it is preferable to set the display so as to sink into the back, or a display in which a display that sinks into the back and a display that appears to float are mixed. This is because the sense of distance that can be sensed between the display of the first shape by the sheet-like display and the display of the second shape by the light-transmitting layer and the light control means described later increases. In the latter case, a stereoscopic effect can be obtained by mixing two different display modes, and the stereoscopic effect and the unexpectedness are improved.
A holographic stereogram is obtained by recording a two-dimensional image viewed from a plurality of different viewpoints as an original image and combining it with a holographic image.
Note that a three-dimensional display method using each of the above methods (and a configuration for realizing the method) is known (for example, Japanese Patent Laid-Open No. 8-194273, International Publication No. 95/09372, and Japanese Patent Laid-Open No. 5-113742). JP, 9-6254, A, etc.).

(Translucent layer and light control means)
The light transmissive layer is disposed in front of the sheet-like display body. Therefore, in the display device of the present invention, the optical means, the sheet-like display body, and the light transmitting layer are arranged in this order.
The light-transmitting layer can be formed using a highly light-transmitting material such as polycarbonate resin, acrylic resin (such as methacrylic resin (PMMA)), epoxy resin, polyethylene terephthalate resin, or glass. The light transmitting layer may be colorless and transparent or colored and transparent. Further, the colors may be partially different. The thickness of the light transmissive layer is not particularly limited. The thickness here can be appropriately set according to the application of the present invention. For example, the thickness of the translucent layer can be set between 1 mm and 10 cm.

  The light that has passed through the sheet-like display is directed to the light-transmitting layer. At least a part of the light is controlled by the light control means when entering the light-transmitting layer, after the light enters the light-transmitting layer, or when exiting from the light-transmitting layer. As a result, a change occurs in the aspect of light emitted forward from the light-transmitting layer, and a desired shape (second shape) is displayed. As described above, in the present invention, the second shape is displayed by utilizing the difference in the form of the emitted light. Control by the light control means includes, for example, light blocking, absorption, reflection, diffusion, color conversion, and the like. Like the combination of diffusion and color conversion, the light control means may be configured to perform two or more types of control.

For example, a light control layer that covers a partial region of the light-transmitting layer and changes the amount and / or color of light passing through the region is used as the light control means. Such a light control layer can be formed on either or both of the light incident surface side (back surface) and the light emitting surface side (front surface) of the light transmitting layer. For example, if a region having a desired shape (second shape) is covered with a light control layer made of a light-impermeable material on the back surface of the light-transmitting layer, light applied to the region is blocked and light applied to other regions Passes through the translucent layer and is taken forward. As a result, light having a shape surrounding the second shape is visually recognized. That is, the second shape is indirectly displayed by light emission from the surroundings. If the same configuration is made using a light control layer made of a colored transparent material, the second shape emits and displays light of a color reflecting the color of the light control layer (the second shape emits light with a color different from the surroundings). ).
Contrary to the above configuration, if a light control layer made of an opaque material is formed in a region other than the second shape, the second shape light is generated. That is, in this configuration, the second shape is directly displayed by light.

  The light control layer can be formed by printing, coating, sticking, or the like of an opaque material or a colored transparent material. If the light control layer contains a phosphor that fluoresces with light from the light emitting means, the second shape can be displayed using fluorescence. With such a configuration, visibility and designability can be improved.

It is also possible to provide a light diffusing / reflecting part in a part of the translucent layer and use this light diffusing / reflecting part as a light control means. The light diffusing / reflecting part is provided on the surface or inside of the light transmitting layer. As a method for forming a light diffusive reflecting portion on the surface of the light transmissive layer, roughening by sandblasting, etching, or electric discharge machining, vapor deposition of light reflecting diffusive material, coating or printing, or light diffusing film or tape The pasting can be exemplified. On the other hand, if laser processing, film-in-mold, or the like is used, a light diffusing / reflecting portion can be provided inside the translucent layer.
If the light reflection diffusing part has a shape corresponding to the second shape (specifically, for example, the second shape light diffusing part is provided on the surface of the light transmitting layer), the light reflected and diffused by the light reflecting diffusing part is used. The second shape can be luminescently displayed. On the other hand, if a light reflecting portion is provided on the surface of the light-transmitting layer so as to surround the second shape region (specifically, for example, the entire region other than the second shape region is a light reflecting diffusion portion), light The light reflected and diffused by the reflection diffusing unit is emitted in the surroundings, and the second shape can be visually recognized.

  A concave portion or a convex portion may be provided in a part of the light transmitting layer, and the concave portion or the like may be used as a light control unit. Specifically, for example, a second-shaped recess is provided on the surface of the translucent layer. In such a configuration, irregular reflection or concentration of light occurs at the edge of the concave portion, whereby the second shape can be displayed.

  A through hole may be provided in a part of the light transmitting layer, and the through hole may be used as a light control means. Specifically, for example, a through hole having a second cross-sectional shape is provided in the light transmitting layer. In such a configuration, the second shape is displayed due to the difference in the mode of light emitted through the through hole and the light emitted through the other region, and the reflection of light by the edge of the through hole. The

  As long as the purpose that the second shape is displayed by the light emitted from the light-transmitting layer is achieved, the light control layer, the light diffusion reflection layer, the concave portion or the convex portion, and the through hole are limited to the above examples. It is not something. For example, the light control layer is used to frame a region having a shape corresponding to the second shape on the surface of the light-transmitting layer so that the light passing through the light control layer acts as a boundary line to display the second shape. Can be formed. A similar configuration can be adopted depending on the light diffusion reflection layer and the like.

(Half mirror layer)
In one embodiment of the present invention, a half mirror layer is provided on the light emitting surface of the light transmitting layer or in front (that is, on the viewer side). In such a configuration, when the display device is in a non-display state (such as when the external illuminance is high during the daytime or the like), the observation surface side of the display device has a metallic tone by the half mirror action. As a result, a unique design property by the metal color is imparted while preventing a decrease in design property due to the inside being observed in the non-display state. On the other hand, when the display device is in a display state, a light emission image such as characters is observed through the half mirror layer. Thus, when shifting from the non-display state to the display state, the color tone / texture on the observation surface side changes abruptly, and characters and the like appear at the same time. As a result, unexpectedness can be produced.
The half mirror layer can be formed using a metal layer (Al, Ag, Au, etc.) having a predetermined thickness, for example. Alternatively, it can be formed by sequentially laminating a metal layer and a protective layer made of a light-transmitting resin or the like. An example of a method for forming such a half mirror layer will be described. First, a metal layer made of an Al thin film is formed. The thickness of the metal layer is such that a half mirror effect can be obtained. For example, the metal layer can have a thickness such that the light transmittance is about 15-20%. Subsequently, a transparent resin such as an epoxy resin is formed on the metal layer by printing, coating or the like to form a protective layer. The configuration of the half mirror layer and the forming method are not limited to this, and any known one can be employed. An ink layer can also be provided on the surface of the protective layer or between the metal layer and the protective layer. The ink layer can be formed, for example, by printing, coating, or the like with a color ink such as yellow.

  A display device 1 which is an embodiment of the present invention is shown in FIGS. 1 is a perspective view of the display device 1, and FIG. 2 is a cross-sectional view taken along the line AA of FIG. Hereinafter, the configuration and display mode of the display device 1 will be described with reference to these drawings. The display device 1 is used for decoration of a scuff plate portion of an automobile.

In the display device 1, an EL element 10 is used as a light emitting means. As shown in FIG. 2, the EL element 10 is disposed at the bottom of the cover 60, and the display body 20 is placed on the EL element 10. A dial 30 is arranged on the display body 20 with a space. The space between the display body 20 and the dial 30 is not essential. However, a certain distance is provided between the display body 20 and the dial 30 by this space, and a more stereoscopic display is possible.
A half mirror film 40 is attached to the upper surface of the dial 30. A protective plate 50 is placed on the half mirror film 40. As described above, in the display device 1, the EL element 10, the display body 20, the dial plate 30, the half mirror film 40, and the protective plate 50 are arranged in this order toward the observation surface (upper side in the drawing). In addition, the planar view shape of each member, such as EL element 10 and the display body 20, is a rectangle of substantially the same shape.

  The EL element 10 has a structure in which a back electrode layer, a dielectric layer, a light emitting layer, and a transparent electrode layer (ITO) are sequentially laminated. Moreover, the protective layer which consists of a translucent film is provided under a back electrode layer and a transparent electrode layer, respectively. When energized through the wiring, planar light is emitted from the light emitting surface (upper surface) of the EL element 10. In this embodiment, the EL element 10 that emits blue light is used. When the vehicle is mounted, power is supplied to the EL element 10 via the harness. Further, a power source control circuit (not shown) is connected to the EL element 10, and the EL element 10 receives, for example, light emission control linked to the vehicle width lamp.

  The display body 20 comprises a microlens array in which hemispherical fine lenses are regularly arranged on the upper surface side (FIG. 3). A stereoscopically visible image 23 is printed on the back surface of the microlens array. In this embodiment, the microlens array is used to generate a stereoscopic image in which regularly arranged Maru V characters appear to sink.

The display body 20 can be obtained by a known method (for example, see International Publication No. 95/09372 pamphlet). Hereinafter, an example of the manufacturing method of the display body 20 is shown. First, a sheet-like base material 21 made of a transparent resin is prepared, and a stereoscopically visible image 23 is printed on the back surface thereof. Next, a resin material that repels the lens-forming resin material is applied to, or printed on, a region where no lens is formed on the lens-forming surface of the base material 21 to form partition lines. Subsequently, a lens-forming resin material is applied, printed, or the like. As a result, the marking line repels the lens-forming resin, and the lens-forming resin material rises in a convex shape within the region surrounded by the marking line. In this state, curing is performed to obtain a microlens array in which fine lenses 22 are regularly arranged. As materials for the base material 21 and the lens 22, various optical resins, glass, and the like can be used. The microlens array obtained by this method includes a base material 21 and a lens 22 formed thereon. However, a microlens array in which a base material and a lens are integrally molded can also be used.
The shape of each lens constituting the microlens array is not particularly limited as long as it enables a desired stereoscopic view. For example, the microlens array may be configured by lenses having a shape smaller than a hemisphere, which is obtained by cutting a sphere in a plane.

  The dial 30 is made of an acrylic resin. Printing using phosphor ink is performed on the area (character area 31) of a desired shape (car character in this embodiment) on the back surface of the dial 30. In this phosphor ink, a phosphor that emits yellow light when excited by blue light is dispersed in a transparent substrate.

  The half mirror film 40 affixed on the upper surface of the dial 30 includes a metal layer made of an Al material. The protective plate 50 placed on the half mirror film 40 is made of polycarbonate resin. The protection plate 50 is provided for the purpose of protecting the half mirror film 40, and preventing dust and water. The upper surface edge of the protection plate 50 is connected to the cover 60 without a gap by a sealing material so that a good dustproof and prevention effect can be obtained.

  The cover 60 is made of stainless steel (SUS) and has a thickness of about 0.5 mm. A rectangular opening is formed on one side of the cover 60 leaving an edge. In the display device 1, the light-emitting character is displayed through the opening. While the cover 60 functions as a protective member, it is an important element constituting the design of the display device 1. In this embodiment, the material of the cover 60 is stainless as described above so as to match the metallic color tone and texture of the half mirror film 40.

A display mode of the display device 1 configured as described above will be described. First, when the external illuminance is high, such as in the daytime, the display device 1 is in a non-display state (the EL element 10 is in a non-light emitting state). At this time, due to the action of the half mirror film 40, the viewing surface side of the display device 1 (excluding the cover 60 portion) exhibits a metallic color tone and texture. On the other hand, when the EL element 10 emits light in conjunction with the lighting of the width lamp when the external illuminance is low, such as at night, when the EL element 10 emits light (display state of the display device 1), the display body 20 first receives the light of the EL element 10 to form a solid. Display. That is, it is displayed in a state in which the letter V of blue light emitting blue is sinked to the back. On the other hand, a part of the light transmitted through the display body 20 irradiates the character area 31 formed on the back surface of the dial 30. This produces yellow light from the phosphor. By mixing the yellow light and the blue light as the irradiation light, the character region 31 emits green light. As a result of the above effects, in the display device 1, the CAR character 31 a that emits green light is observed, and at the same time, the Maru V character 21 that emits blue light so that it appears to sink to the back is observed. (FIG. 4). Since the two types of characters are observed with different senses of distance as described above, the light emission mode is rich in three-dimensionality or depth, and gives unexpectedness.
By the way, the use of a microlens array as a display body for performing stereoscopic display can suppress the occurrence of an unpleasant flicker phenomenon. As a result, a light emission mode excellent in decorativeness and luxury can be obtained regardless of the viewing angle. On the other hand, the change in the appearance of the Maru V character 21 when the viewing angle is changed is not the same as the change in the appearance of the CAR character 31a, and is specific to stereoscopic vision. As a result, it is possible to give an impression as if the V-shaped character 21 is moving inside the display device 1.
As described above, in the display device 1, although it is thin, a display with a rich stereoscopic effect and a depth feeling and unexpectedness is performed. As a result, a high decorative effect is brought about and a high-class feeling is also obtained. By the way, in the display device 1, due to the action of the half mirror film 40, characters suddenly appear when the display device 1 shifts to the display state. Thereby, the unexpectedness at the moment of shifting to the display state can also be produced.

  In the embodiment described above, all the characters 31a are displayed in the same manner, but a display mode that is more varied can be realized by devising the method of forming the character region 31. For example, if the type of phosphor ink used for forming the character region 31 is changed for each character, it is possible to obtain a display mode in which the luminescent color differs between characters.

  In the embodiment described above, the area printed on the back surface of the dial 30 is the character area 31, but conversely, the area not printed may be the character area. FIG. 5 shows an example of a display mode when the configuration is adopted. In the example of FIG. 5, the entire back surface of the dial plate 30 is printed with a non-transparent ink except for a part of the area (that is, the character of CAR). As a result, the CAR shape 32 is visually recognized by the light from the rear, and the round V character 21 is observed in the back of the CAR shape 32. As described above, in this configuration, an unexpected light emission mode with a high degree of taste is obtained, in which characters are three-dimensionally displayed in the characters. In addition, a spatial expansion can be produced.

  Another embodiment of the present invention is shown in FIG. FIG. 6 is a cross-sectional view of the display device 2 of this embodiment and corresponds to FIG. In addition, the same code | symbol is attached | subjected to the member same or equivalent to the said Example, and the description is abbreviate | omitted.

  In the display device 2, an LED lamp 70 and a light guide plate 71 are used as light emitting means. A light guide plate 71 is disposed under the display body 20, and an LED lamp 70 is provided at a position facing the end surface of the light guide plate 71. The LED lamp 70 is a bullet type (lens type) and emits blue light. In this embodiment, light is incident from the left and right end surfaces of the light guide plate 71, and a total of two LED lamps are used. The number of LED lamps can be increased or decreased as necessary. In addition, light is not incident from the left and right end surfaces of the light guide plate 71 as in this embodiment, but light is incident only from either the left or right end surface, or light is also incident from the upper and lower end surfaces in addition to the left and right end surfaces. For example, various incident methods can be adopted.

  The design of the display device 2 in the non-display state (the LED lamp 70 is in the non-light-emitting state) is the same as that in the above embodiment, that is, a metallic design is exhibited by the action of the half mirror film 40. On the other hand, in the display state, the LED lamp 70 is lit and the following display mode is set. First, light from the LED lamp 70 enters the light guide plate 71. The incident light is guided through the light guide plate 71 and then emitted from the light emitting surface (upper surface) of the light guide plate 71. The planar light generated in this way is used for stereoscopic display by the display body 20 and character display by the character region 31. As a result, a light emission mode similar to that of the display device 1 of the above embodiment is obtained.

  Although the application example of the present invention has been described above, the display device of the present invention is not limited to the scuff part, but decorations of various parts of the automobile (for example, a center cluster part, a steering wheel, a back garnish part, a door part, a pillar part, etc. This can also be applied to the display of the logo mark. Further, the present invention can be applied not only to automobiles but also to decorations such as display plates in various vehicles, and decorations such as display plates used in the interior or exterior of buildings (houses, buildings, etc.). Furthermore, the present invention can also be applied to decorating a ceiling in a vehicle interior or building. In such a usage mode, in addition to the decorative effect, it is possible to give a sense of depth to the space or produce a feeling of openness. In this way, the present invention can be used as a means of space production.

The present invention is not limited to the description of the embodiments and examples of the invention described above. Various modifications may be included in the present invention as long as those skilled in the art can easily conceive without departing from the description of the scope of claims.
