Abstract
Description
[Technical field]
[0001] The present invention relates to an image display method and a display device. [Background technology]
[0002] Conventionally, decorative sheets have been known as decorative sheets for walls, etc., which include a base material and a printed layer provided on the surface of the base material, and the printed layer has a pattern such as a wood grain pattern, an abstract pattern, etc. On a wall surface to which this decorative sheet is provided, the pattern is always visible.
[0003] A display device has been developed that allows such a decorative sheet to have optical transparency, and then places a monitor or the like on the back side of the decorative sheet, and displays a pattern different from that of the printed layer when the monitor is turned on. For example, Patent Document 1 describes a display device having a display that is fitted into a mounting portion and emits display light to the outside when turned on, in which the front of the display is covered with a screen having a large number of fine holes that can transmit the display light, and the surface of the screen is set to the same color and pattern as the mounting portion around the display. According to the display device of Patent Document 1, when the display is turned on, the image display portion can be seen through the fine holes of the screen, but when the display is not turned on, the screen hides the display, so that the entire display, including the portion where the display is fitted, is unified with the pattern of the screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that the drawings are schematic, and for example, the relationship between thickness and planar dimensions, and the ratio of thicknesses of each layer are different from the actual ones. In addition, the embodiments shown below are examples of configurations for embodying the technical idea of the present invention, and the technical idea of the present invention is not limited to the materials, shapes, structures, etc. of the components described below.
[0011] <Display device> 1 is a cross-sectional view showing a schematic state in which a display device 100 according to this embodiment is installed on a wall surface W. The display device 100 includes a monitor 30 having an image display unit 32, and a decorative sheet 10 arranged on the image display unit 32 side of the monitor 30. The decorative sheet 10 is arranged on the image display unit 32 side of the monitor 30. The installation location of the display device is not limited to a wall surface, and it may be arranged as a part of a vehicle component, a home appliance, etc.
[0012] (decorative sheet) Fig. 2 is a cross-sectional view showing a schematic diagram of the decorative sheet 10 included in the display device shown in Fig. 1. The decorative sheet 10 includes at least a printed layer 5 on which a pattern is printed, and includes, for example, a light-transmitting base material 4, a printed layer 5, and a translucent smoke printed layer 3. The decorative sheet 10 is transmissive to visible light, and the structure is not particularly limited as long as the image displayed on the image display unit 32 of the monitor 30 can be visually recognized when the image is viewed through the decorative sheet 10.
[0013] The light-transmitting substrate 4 is a substrate having visible light transmissibility. The light-transmitting substrate 4 is made of, for example, a transparent resin. Examples of the transparent resin include PET, PMMA, polyethylene, polypropylene, and nylon. The light-transmitting substrate 4 may be a glass substrate. The light-transmitting substrate 4 has a thickness of, for example, 25 to 250 μm. In the case of a glass substrate, the thickness is, for example, several mm to about 10 mm. The decorative sheet 10 may have a surface protective layer on the surface side of the light-transmitting substrate 4 (the side opposite to the printed layer 5) as necessary.
[0014] The printed layer 5 is a layer that expresses the color and pattern of the decorative sheet 10. The printed layer 5 includes, for example, a first color pattern layer 1 provided on one surface 4a of the light-transmitting base material 4, and a second color pattern layer 2 provided on the first color pattern layer 1.
[0015] The first color pattern layer 1 can be provided on the surface 4a by, for example, screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 3, the first color pattern layer 1 is composed of a plurality of first color dots 11. Here, the "dot" means a point that is an element that constitutes a printed image, and the shape is not limited to a circle, and may be a rectangle, a polygon, or other shape. Each of the plurality of first color dots 11 includes a first color binder 12 and a plurality of first color pigment chips 13 dispersed inside the first color binder 12. The content of the plurality of first color pigment chips 13 may be, for example, 0.5 to 20 parts by mass when the first color binder 12 is 100 parts by mass.
[0016] Examples of the first color binder 12 include vinyl resins, acrylic resins, thermoplastic urethane resins, polyester resins, and polycarbonate resins. The thickness of the first color pattern layer 1 is, for example, 1 to 10 μm. The first color pattern layer 1 may contain a curing agent from the viewpoint of improving the heat resistance of the first color pattern layer 1 and the adhesion of the first color pattern layer 1 to the light-transmitting substrate 4.
[0017] The first color pigment chips 13 are, for example, first interference pigments 14a and 14b of multiple colors that generate different interference lights. Each of the first interference pigments 14a and 14b is, for example, composed of a flake having visible light transparency and a metal oxide film that covers the flake. As a result, the light reflected on the surface of the metal oxide film out of the light incident on the first color pattern layer 1 from the translucent substrate 4 side interferes with the light that passes through the metal oxide film and is reflected on the surface of the flake, generating interference light. By adjusting the film thickness and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.
[0018] Each of the first interference pigments 14a and 14b may be titanium dioxide-coated mica. The particle size range of the titanium dioxide-coated mica may be, for example, 25 to 60 μm. The "particle size" refers to the longest diameter of the particle cross section. The flakes constituting the first interference pigments 14a and 14b may be other than mica, and may be silica, alumina, glass, polysilicate, or the like. The metal oxide film constituting the first interference pigments 14a and 14b may be other than titanium dioxide, and may be zirconium oxide, zinc oxide, iron oxide, tin oxide, or the like.
[0019] When the incident light E is incident on the first color pattern layer 1, the first interference pigments 14a and 14b generate first interference lights 15a and 15b that are different from each other. That is, the wavelengths of the first interference lights 15a and 15b are different from each other. As a result, the first interference pigments 14a and 14b exhibit a mixed color. The first interference pigments 14a and 14b are, for example, a red interference pigment (red pearl pigment) and a gold interference pigment (gold pearl pigment), respectively. In this case, the first interference lights 15a and 15b exhibit red and gold, respectively. The blending amounts of the first interference pigments 14a and 14b may be the same or different from each other.
[0020] The second color pattern layer 2 can be provided on the first color pattern layer 1 by, for example, screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 3, the second color pattern layer 2 is composed of a plurality of second color dots 21. Each of the plurality of second color dots 21 includes a second color binder 22 and a plurality of second color pigment chips 23 dispersed inside the second color binder 22. The content of the plurality of second color pigment chips 23 may be, for example, 0.5 to 20 parts by mass, assuming that the second color binder 22 is 100 parts by mass.
[0021] Examples of the second color binder 22 include vinyl resins, acrylic resins, thermoplastic urethane resins, polyester resins, and polycarbonate resins. The thickness of the second color pattern layer 2 is, for example, 1 to 10 μm. The second color pattern layer 2 may contain a curing agent from the viewpoint of improving the heat resistance of the second color pattern layer 2 and the adhesion of the second color pattern layer 2 to the first color pattern layer 1.
[0022] The second color pigment chips 23 are, for example, second interference pigments 24 that generate monochromatic interference light different from the mixed color represented by the first interference pigments 14a and 14b. The second interference pigment 24 is, for example, composed of flakes having visible light transparency and a metal oxide film covering the flakes. As a result, light reflected on the surface of the metal oxide film out of the incident light from the translucent substrate 4 side to the second color pattern layer 2 interferes with light that passes through the metal oxide film and is reflected on the surface of the flakes, generating interference light. By adjusting the film thickness and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.
[0023] The second interference pigment 24 may be titanium dioxide-coated mica. The particle size range of the titanium dioxide-coated mica may be, for example, 25 to 60 μm. The flakes constituting the second interference pigment 24 may be other than mica, and may be silica, alumina, glass, polysilicate, or the like. The metal oxide film constituting the second interference pigment 24 may be other than titanium dioxide, and may be zirconium oxide, zinc oxide, iron oxide, tin oxide, or the like.
[0024] When the incident light L is incident on the second color pattern layer 2, the second interference pigment 24 generates a monochromatic second interference light 25. As a result, the second interference pigment 24 exhibits a monochromatic color. The second interference pigment 24 may be an interference pigment that generates a monochromatic second interference light 25 different from the mixed color exhibited by the first interference pigments 14a and 14b, and may be, for example, a green interference pigment (green pearl pigment). In this case, the second interference light 25 exhibits green color.
[0025] The transmissive smoke printed layer 3 has a function of attenuating light from the front side of the viewpoint that passes through the decorative sheet 10. The transmissive smoke printed layer 3 is provided on the outermost surface of the printed layer 5 on the opposite side to the translucent substrate 4. As shown in FIG. 2, the transmissive smoke printed layer 3 is provided on the second color pattern layer 2. The transmissive smoke printed layer 3 can be provided on the second color pattern layer 2 by, for example, screen printing, inkjet printing, gravure printing, or offset printing using an ink in which a small amount of carbon black is dispersed in a resin binder such as a vinyl-based, acrylic-based, urethane-based, or polyester-based resin binder. The transmissive smoke printed layer 3 has a thickness of, for example, 1 to 10 μm.
[0026] The decorative sheet 10 has a transparent smoke printed layer 3 provided on the second color pattern layer 2, thereby providing excellent color development between the first color pattern layer 1 and the second color pattern layer 2. Furthermore, since the transparent smoke printed layer 3 has transparency, a decrease in visibility of the image of the display device 100 is effectively suppressed.
[0027] The decorative sheet 10 may include a white pattern layer composed of a plurality of silver dots instead of the transparent smoke printed layer 3, or may include a white pattern layer between the printed layer 5 and the transparent smoke printed layer 3. The white pattern layer can be provided on the second color pattern layer 20 by, for example, screen printing, inkjet printing, gravure printing, or offset printing. Each of the plurality of silver dots includes a silver binder and a plurality of silver pigment chips dispersed inside the silver binder. The content of the plurality of silver pigment chips may be, for example, 0.5 to 20 parts by mass when the silver binder is taken as 100 parts by mass.
[0028] Examples of the binder for silver include vinyl resin, acrylic resin, thermoplastic urethane resin, polyester resin, polycarbonate resin, etc. The thickness of the white pattern layer is, for example, 1 to 10 μm. The white pattern layer may contain a curing agent from the viewpoint of improving the heat resistance of the white pattern layer and the adhesion of the white pattern layer to the second color pattern layer 20.
[0029] The decorative sheet 10 can express colors and patterns by additively mixing the first interference light 15a, 15b generated by the first interference pigments 14a, 14b and the second interference light 25 generated by the second interference pigment 24.
[0030] The visible light transmittance of the decorative sheet 10 is, for example, 30 to 70%. The visible light transmittance can be measured using a spectrophotometer (for example, spectrophotometer UV-2100 manufactured by Shimadzu Corporation).
[0031] (Monitor) The monitor 30 has an image display unit 32. The monitor is a device that emits light, such as a liquid crystal monitor, an organic EL monitor, an LED monitor, or a projection monitor. The monitor 30 may have a light source therein. The monitor 30 is fixed to a wall W, for example.
[0032] The monitor 30 displays an image on the image display unit 32 in which the tone of black has been changed so that the color of the printed layer 5 of the decorative sheet 10 and the pattern printed on the printed layer 5 are difficult to see when the viewer looks at the image display unit 32 through the decorative sheet 10. By changing the tone, particularly the brightness, even if there is black in the image displayed by the image display unit 32, light is transmitted through the black portion, and the color of the printed layer 5 of the decorative sheet 10 and the pattern printed on the printed layer 5 are difficult to see when the viewer looks at the image display unit 32 through the decorative sheet 10. The optimal adjustment amount of the tone (brightness) when changing the tone of the black portion to transmit light depends on the characteristics of the decorative sheet 10 (visible light transmittance, etc.). Therefore, it is preferable to adjust the tone (brightness) appropriately so that the color of the printed layer 5 of the decorative sheet 10 and the pattern printed on the printed layer 5 are difficult to see. The tone may be changed in brightness and saturation, and it is preferable to change only the brightness.
[0033] The monitor 30 may display an image in which the black tone has been changed on the image display section 32 so that the viewer recognizes the color of the image displayed on the image display section 32 after the black tone has been changed as black when the viewer looks at the image display section 32 through the decorative sheet 10. This allows an image close to the image before the black tone has been changed to be displayed. For example, by changing the tone, particularly the brightness, of the color surrounding the black of the image (the color after the black tone has been changed) to increase the amount of light transmitted through the decorative sheet 10, the black of the image appears blacker relative to the surrounding colors, making it easier for the viewer to recognize the color of the image after the black tone has been changed as black. More specifically, if the color surrounding the black of the image is gray, the brightness of the black is increased to approach white, while the brightness of the surrounding gray is also increased to approach white, making it easier for the viewer to recognize the color of the image after the black tone has been changed as black.
[0034] Fig. 4 is a front view showing an example of the state of the surface on the F1 side of the display device 100. Fig. 4(a) shows a state in which no image is displayed on the image display unit 32. In a state in which no image is displayed on the image display unit 32, when a viewer looks at the image display unit 32 through the decorative sheet 10, only the pattern (e.g., a wood grain pattern) printed on the printing layer 5 of the decorative sheet 10 is visible, and it appears as if the monitor 30 does not exist.
[0035] 4(b) shows a state in which an image is displayed on the surface of the display device 100 without changing the black color tone of the image on the image display unit 32. In this state, when a viewer looks at the image display unit 32 through the decorative sheet 10, the white background area A2 on the surface of the display device 100 appears white because the color of the printed layer 5 of the decorative sheet 10 and the pattern printed on the printed layer 5 are not visible, but the color of the printed layer 5 of the decorative sheet 10 and the pattern printed on the printed layer 5 are visible in the black circle area A1, just as in the state in which no image is displayed.
[0036] 4(c) shows a state in which an image is displayed on the surface of the display device 100 by changing the black tone of the image on the image display unit 32. In this state, when a viewer looks at the image display unit 32 through the decorative sheet 10, the pattern printed on the printing layer 5 of the decorative sheet 10 is not visible in the white background area B2 on the surface of the display device 100, and the area appears white. On the other hand, by changing the black tone of area A1 (for example, by increasing the brightness of the black in area A1 to make it gray, etc.), the color of the printing layer 5 of the decorative sheet 10 and the pattern printed on the printing layer 5 are less visible to the viewer, and area A1 can be recognized as black.
[0037] The monitor 30 may have a function of adjusting the output of the black and white gradation of black in the image displayed on the image display unit 32. That is, the monitor 30 may display an image with a changed black tone on the image display unit 32 by adjusting the output of the black and white gradation of black in the image displayed on the image display unit 32. When a continuously changing image or the like is displayed on the image display unit 32, it is difficult to change the black tone itself in the image, so that the image printed on the printing layer 5 of the decorative sheet 10 can be made difficult to easily see by adjusting the output of the black and white gradation of black in the image displayed on the image display unit 32.
[0038] Methods for adjusting the black and white gradation output include, for example, increasing the lower limit of the gradation of the image displayed in 8-bit gray (256 gradations), where black corresponds to 0 and white corresponds to 255, and shifting the range of gradations of the image displayed in 8-bit gray (256 gradations) toward the white side.
[0039] The monitor 30 may display an image in which the tone of black has been changed in advance on the image display unit 32. That is, the monitor 30 may display an image in which the tone of black has been changed in advance on the image display unit 32, thereby displaying an image in which the tone of black has been changed on the image display unit 32. When displaying simple animations or characters on the image display unit 32, it is easy to change the tone of black in advance at the stage of creating the image, so that the pattern printed on the printing layer 5 of the decorative sheet 10 can be easily made difficult to see by displaying an image in which the tone of black has been changed in advance on the image display unit 32. Also, by displaying an image in which the tone of black has been changed in advance on the image display unit 32, it is possible to display only specific characters or images on the surface of the display device 100, and to make the pattern printed on the printing layer 5 of the decorative sheet 10 visible in the area other than the characters, etc.
[0040] One method for creating an image in which the color tone of black has been changed in advance is to change in advance, for example, the parts of an image to be displayed on a display device that the viewer should recognize as black, to gray, navy blue, or the like.
[0041] The monitor 30 may increase the luminance contrast of the colors other than black in the image and display the image on the image display unit 32. By increasing the luminance contrast of the colors other than black in the image and displaying the image on the image display unit 32, the viewer can more easily recognize that the color after the hue of the black in the image is changed is black.
[0042] The display device 100 may include a support 40 that supports the decorative sheet 10, in addition to the monitor 30 and the decorative sheet 10. That is, the display device 100 may also include a display device housing 50 that includes the decorative sheet 10 and the support 40 that supports the decorative sheet 10, and the monitor 30. The support 40 is made of a material (e.g., iron) that can ensure strength, and is fixed to the wall surface W by a jig (not shown). The support 40 has an opening (window) 42. The monitor 30 is disposed in the opening 42. The surface 30S of the monitor 30 and the surface 40S of the support 40 may be substantially on the same plane. The decorative sheet 10 may be attached to a base material (e.g., glass) that is transparent to visible light, and the base material that is transparent to visible light may be integrated with the support 40.
[0043] <Image display method> Another embodiment of the present invention is an image display method in a display device. The display device includes a monitor having an image display section, and a decorative sheet including a print layer on which a pattern is printed, having visible light transparency, and disposed on the image display section side of the monitor. The image display method is a method for making it difficult to visually recognize the pattern printed on the decorative sheet in a black portion of an image displayed on the monitor, even if the image includes black.
[0044] The image display method includes changing the tone of black in the image displayed on the image display unit so that the pattern is difficult to see when a viewer looks at the image display unit through the decorative sheet, whereby even if black is present in the image displayed by the image display unit, the pattern printed on the printing layer of the decorative sheet is difficult to see when a viewer looks at the image display unit through the decorative sheet.
[0045] The image display method may change the color tone of the black in the image so that a viewer recognizes the color after the change in the black color tone in the image as black when viewing the image display portion through the decorative sheet, thereby making it possible to display an image close to the image before the change in the black color tone.
[0046] The image display method may adjust the output of the black and white gradation of black in the image displayed on the image display unit. That is, the image display method may display an image with a changed black tone on the image display unit by adjusting the output of the black and white gradation of black in the image displayed on the image display unit. When a continuously changing image or the like is displayed on the image display unit, it is difficult to change the black tone itself in the image, so that the image printed on the printing layer of the decorative sheet can be made difficult to easily see by adjusting the output of the black and white gradation of black in the image displayed on the image display unit.
[0047] The image display method may be such that an image with a changed black tone is created in advance as an image to be displayed on the image display unit, and the image with the changed black tone is displayed on the image display unit. That is, the image display method may be such that an image with a changed black tone is displayed on the image display unit by displaying an image with a changed black tone on the image display unit. When simple animations or characters are to be displayed on the image display unit, it is easy to change the black tone in advance at the stage of creating the image, so that the pattern printed on the printing layer of the decorative sheet is difficult to easily see by displaying an image with a changed black tone on the image display unit. In addition, by displaying an image with a changed black tone on the image display unit, only specific characters or images can be displayed on the surface of the display device, and the pattern printed on the printing layer of the decorative sheet can be seen in the area other than the characters, etc.
[0048] The image display method may display the image on the image display unit with the luminance contrast of the parts other than black in the image increased. By displaying the image on the image display unit with the luminance contrast of the parts other than black in the image increased, the viewer can more easily recognize that the color after the color tone of the black in the image is changed is black. EXAMPLES
[0049] EXAMPLES Hereinafter, examples of the present invention and comparative examples will be described, but the present invention is not limited to the following examples.
[0050] Example 1 A 50μm thick PET film (transparent substrate) was used as the substrate, and a wood grain pattern was printed on one surface with an interference pigment to create a decorative sheet. The decorative sheet was attached to a monitor to create a display device.
[0051] An image was prepared in which a circle was drawn in the center of the inside of a rectangle, the area inside the circle was gray, and the area inside the rectangle and outside the circle was white. When the image was displayed on the image display unit of a monitor and the image display unit was viewed through the decorative sheet, the image prepared on the surface of the display device facing the decorative sheet could be seen as shown in Figure 4(c). When the inside of the circle in the image displayed on the surface of the display device facing the decorative sheet was checked, the wood grain pattern of the decorative sheet was barely visible.
[0052] Comparative Example 1 An image was prepared in the same manner as in Example 1, except that an image was prepared in which the area inside the circle was black and the area inside the rectangle and the area outside the circle was gray. When the image display unit was viewed through the decorative sheet, the image prepared on the surface of the display device facing the decorative sheet was visible.
