Patent Description:
In the related art, in an in-vehicle device, a mobile device, or the like having a display function, a cover component is used for the purpose of protecting a surface of a display panel such as a liquid crystal panel or an organic EL panel, preventing the surface from being stained, or decorating an edge of the display panel (For example, PTLs <NUM> and <NUM>). Another cover component is known from <CIT>.

In such a cover component, for example, a hard coat layer having functions of protecting a display panel and preventing the display panel from being stained and a decorative layer having a decorating function are provided on a transparent substrate. The decorative layer includes a colored layer having a frame shape and a transmissive region provided inside the colored region. The transmissive region is a space for displaying contents of the display panel. The colored region is a region for imparting a design to the edge of the display panel.

The light generated from an inside of the display panel, such as backlight of the liquid crystal panel or light generated from the organic EL panel itself, may pass through the transmissive region and cause a viewer to dazzle. In addition, light outside the display panel, such as sunlight or illumination light, may reflect on the surface of the cover component to cause glitter (also called glare) to the viewer.

Therefore, in the hard coat layer, it is conceivable that a fine uneven shape is provided on a surface of a region overlapping with the transmissive region of the decorative layer. When providing the fine uneven shape on a surface of the hard coat layer, light from an inside of a display panel side and light from the outside of the display panel can be diffused in the hard coat layer and dazzling to the viewer can be reduced.

The invention is as set out in the independents claims, further aspects of the invention are outlined in the dependent claims. Embodiments that do not fall within the scope of the claims do not describe part of the invention.

According to the cover component according to the present disclosure, the anti-reflection region having the fine uneven shape formed at least one surface covers the transmissive region and protrudes into the colored region over the whole inner peripheral portion of the colored region. Therefore, even when a positional shift occurs between the anti-reflection region and the transmissive region, since the anti-reflection region overlaps the transmissive region, it is possible to reduce the above-described light leakage and glare and prevent a quality of the cover component from deteriorating.

Before explaining embodiments, problems in the related art will be briefly explained.

In a hard coat layer having functions of protecting a display panel and preventing the display panel from being stained, in an aspect in which a fine uneven shape is provided only in a region overlapping with a transmissive region, alignment between the fine uneven shape and the transmissive region has to be strictly performed. That is, when there is even a slight positional shift between the fine uneven shape and the transmissive region, a region where the fine uneven shape and the transmissive region do not overlap in plan view is generated. Light inside the display panel leaks from the non-overlapping region to the outside and may cause the viewer to dazzle. (Hereinafter, leakage of the light inside the display panel to the outside is simply referred to as "light leakage". Light outside the display panel is reflected in the non-overlapping region to generate glare and may cause the viewer to dazzle.

An object of the present disclosure is to prevent the quality from deteriorating due to light leakage or glare, in a cover component of the display panel.

Hereinafter, cover component <NUM> of Embodiment <NUM> will be described with reference to the drawings. <FIG> is an exploded perspective view of cover component <NUM> of Embodiment <NUM>. <FIG> is a plan view of cover component <NUM>. <FIG> is a side sectional view of cover component <NUM>. Cover component <NUM> is attached to a display panel of an in-vehicle display device, a mobile device, of the like and includes hard coat layer <NUM>, decorative layer <NUM>, adhesive layer <NUM>, and transmissive substrate <NUM>.

Hard coat layer <NUM> is a transparent resin layer such as a layer of polyethylene terephthalate (PET), and is provided at the outermost surface of cover component <NUM>. Hard coat layer <NUM> overlaps decorative layer <NUM> below hard coat layer <NUM>. Decorative layer <NUM> includes colored region <NUM> having a frame shape and transmissive region <NUM> provided inside the colored region. Transmissive region <NUM> is a space for displaying contents of the display panel. However, transmissive region <NUM> may be a light-transmissive material fitted inside colored region <NUM>.

Adhesive layer <NUM> for bonding with transmissive substrate <NUM> is provided below decorative layer <NUM>. A thickness of hard coat layer <NUM> is, for example, approximately <NUM>. A thickness of decorative layer <NUM> is, for example, approximately several µm. A thickness of adhesive layer <NUM> is, for example, approximately <NUM> to <NUM>. A thickness of transmissive substrate <NUM> is, for example, <NUM>.

Hard coat layer <NUM> includes anti-reflection region <NUM> and region <NUM> around anti-reflection region <NUM>. Fine uneven shape 46a is provided on a surface of anti-reflection region <NUM>. Anti-reflection region <NUM> covers transmissive region <NUM> of decorative layer <NUM> and protrudes into colored region <NUM> over a whole inner peripheral portion of colored region <NUM>. That is, fine uneven shape 46a overlaps transmissive region <NUM> and protrudes to an inside of colored region <NUM> in a plan view (as viewed from a direction perpendicular to each layer). The surface of region <NUM> around anti-reflection region <NUM> has a smooth shape.

According to cover component <NUM> of the present embodiment, it is possible to prevent the quality of the cover component from deteriorating. For example, in hard coat layer <NUM>, in an aspect in which a fine uneven shape is provided only in a region overlapping with transmissive region <NUM>, alignment between anti-reflection region <NUM> and transmissive region has to be strictly performed. That is, when there is even a slight positional shift between anti-reflection region <NUM> and transmissive region <NUM>, a region where anti-reflection region <NUM> and transmissive region <NUM> do not overlap in plan view is generated. Light inside the display panel, such as backlight or light generated from the organic EL leaks from the non-overlapping region to the outside and may cause the viewer to dazzle. In addition, light outside the display panel, such as sunlight or illumination light is reflected in the non-overlapping region to generate glare and may cause the viewer to dazzle.

On the other hand, according to cover component <NUM> of the present disclosure, anti-reflection region <NUM> in which fine uneven shape 46a is provided on a surface covers transmissive region <NUM> and protrudes into colored region <NUM> over the whole inner peripheral portion of colored region <NUM>. Therefore, even when a positional shift occurs between anti-reflection region <NUM> and transmissive region <NUM>, since anti-reflection region <NUM> overlaps transmissive region <NUM>, it is possible to reduce the above-described light leakage and glare and prevent a quality of the cover component from deteriorating.

Here, in the present embodiment, transmissive region <NUM> and anti-reflection region <NUM> have rectangular shapes having a long side and a short side in plan view. When a length of the long side of anti-reflection region <NUM> is represented as Ax, a length of the short side of anti-reflection region <NUM> is represented as Ay, a length of the long side inside colored region <NUM> is represented as Bx, the length of the short side inside colored region <NUM> is By, and colored region <NUM> is positioned at the center of anti-reflection region <NUM> in plan view, it is preferable that conditions of <NUM> ≤ (Ax - Bx)/<NUM> ≤ <NUM> and <NUM> ≤ (Ay - By)/<NUM> ≤ <NUM> are satisfied. (Ax - Bx)/<NUM> is a dimension that anti-reflection region <NUM> protrudes into colored region <NUM> in a long side direction. (Ay - By)/<NUM> is a dimension that anti-reflection region <NUM> protrudes into colored region <NUM> in a short side direction.

In a case where a dimension that anti-reflection region <NUM> protrudes into colored region <NUM> is less than <NUM> in each side, a region in which anti-reflection region <NUM> and transmissive region <NUM> do not overlap when cover component <NUM> is viewed obliquely is generated, and light leakage and glare may occur. On the other hand, in a case where the dimension that anti-reflection region <NUM> protrudes into colored region <NUM> is more than <NUM>, fine uneven shape 46a becomes conspicuous in colored region <NUM>. Therefore, there is a design problem. Accordingly, it is preferable to satisfy the above conditions. In the drawings, the dimension that anti-reflection region <NUM> protrudes into colored region <NUM> is drawn exaggeratingly in order to explain the contents of the present embodiment.

In fine uneven shape 46a provided on the surface of anti-reflection region <NUM>, it is preferable that an arithmetic average roughness (Ra) is more than <NUM> and less than <NUM> and a root mean average roughness (Rms) is more than <NUM> and less than <NUM>. The reason why is as follows. In a case where the arithmetic average roughness (Ra) is <NUM> or less, the antiglare property decreases. On the other hand, in a case where the arithmetic average roughness (Ra) is more than <NUM>, a light diffusing effect increases and white blur in a screen occurs. In addition, the reason why is as follows. In a case where the root mean average roughness (Rms) is <NUM> or less, the antiglare property decreases. On the other hand, in a case where the root mean average roughness (Rms) is more than <NUM>, diffusion of light increases and the white blur in the screen occurs.

It is preferable that fine uneven shape 46a includes uneven shapes having two-steps of size (first uneven shape 46aa and second uneven shape 46ab) as shown in <FIG>. In the aspect shown in <FIG>, first uneven shape 46aa is provided on the surface of anti-reflection region <NUM>, and second uneven shape 46ab is provided on a surface of first uneven shape 46aa. First uneven shape 46aa has an arithmetic average roughness (Ra) of around <NUM> (for example, <NUM> or more and <NUM> or less) and a root mean average roughness (Rms) of around <NUM> (for example, <NUM> or more and <NUM> or less). Second uneven shape 46ab has an arithmetic average roughness (Ra) of around <NUM> (for example, <NUM> or more and <NUM> or less) and a root mean average roughness (Rms) of around <NUM> (for example, <NUM> or more and <NUM> or less). According to this aspect, it is possible to reduce glare due to pixel interference from the display panel with second uneven shape 46ab while securing antiglare property with first uneven shape 46aa, and it is possible to improve the quality of the cover component. For example, in a case where there is only first uneven shape 46aa, when a size of first uneven shape 46aa is close to a pixel size of the display panel, first uneven shape 46aa acts like a lens so that the pixel is enlarged, and the glare on a display of the display panel may occur. However, it is possible to prevent such glare from occurring by providing second uneven shape 46ab on the surface of first uneven shape 46aa.

A material of the transmissive substrate <NUM> is, for example, a general purpose resin to be formed, such as polycarbonate (PC) resin, poly(methylmethacrylate) (PMMA) resin, ABS resin, polystyrene (PS) resin, or polyolefin resin. In a case where transfer, UV (ultraviolet) exposure, or the like is used without using injection molding, it is also possible to cope with resin that requires forming at a high temperature, such as resin for optical applications or super engineering resin. A material of adhesive layer <NUM> is not particularly limited as long as the material has good adhesiveness with transmissive substrate <NUM>.

Although the present embodiment adopts an aspect in which transmissive region <NUM> and anti-reflection region <NUM> each have rectangular shapes in plan view, the cover component of the present embodiment is not limited to the aspect. For example, shapes of transmissive region <NUM> and anti-reflection region <NUM> may be a circular shape, and shapes of transmissive region <NUM> and anti-reflection region <NUM> may be different from each other. As long as anti-reflection region <NUM> is formed to cover transmissive region <NUM> and protrude into colored region <NUM> over the whole inner peripheral portion of colored region <NUM>, it is possible to achieve the object.

Although the present embodiment adopts an aspect in which fine uneven shape 46a is provided on the surface of anti-reflection region <NUM> of hard coat layer <NUM>, the cover component of examples not falling under the scope of protection are not limited to the aspect. For example, fine uneven shape 46a may be provided on a back surface of anti-reflection region <NUM>, that is, on decorative layer <NUM> side, or may also be provided on both the surface and the back surface (both surfaces). In other words, a fine uneven shape may be formed in at least one surface of anti-reflection region <NUM>.

According to other examples not falling under the scope of protection, hard coat layer <NUM> may not include anti-reflection region <NUM> and an anti-reflection layer including an anti-reflection region may be separately provided. In other words, although the present embodiment adopts an aspect in which hard coat layer <NUM> having functions of protecting a display panel and preventing the display panel from being stained, also serves as a role of an anti-reflection layer having a function of anti-reflection, the cover component of the aspect may adopt an aspect in which a hard coat layer and an anti-reflection layer are separately provided.

<FIG> is a plan view of a transfer film used for manufacturing the cover component of Embodiment <NUM>. <FIG> is a sectional view of the transfer film. Transfer film <NUM> is formed by stacking base film <NUM>, peelable layer <NUM>, hard coat layer <NUM>, decorative layer <NUM>, and adhesive layer <NUM> in this order.

Base film <NUM> is a belt-like member, and is made of, for example, polyethylene terephthalate (PET). Since configurations of hard coat layer <NUM>, decorative layer <NUM>, and adhesive layer <NUM> are the same as the configurations of cover component <NUM>, a detailed description of the same configurations will be omitted. Peelable layer <NUM> is interposed between base film <NUM> and hard coat layer <NUM>. Hard coat layer <NUM> is made to be easily released from base film <NUM> by peelable layer <NUM>.

Examples of methods for forming each of the layers on base film <NUM> include vacuum film formation, gravure printing, screen printing, and ink jet printing. In addition, in the present embodiment, in order to favorably form the fine uneven shape, it is preferable that hard coat layer <NUM> is an after-cure type in which UV (ultraviolet) curing is performed after forming.

Hereinafter, examples of a manufacturing apparatus and a manufacturing method of the cover component of Embodiment <NUM> will be described with reference to <FIG>. The cover component of the present embodiment is manufactured by an insertion forming method by manufacturing apparatus <NUM>. Manufacturing apparatus <NUM> includes: first die <NUM> having projection portion <NUM>, suction hole <NUM>, and vacuum pump <NUM>; second die <NUM> having recess portion <NUM>, spool <NUM>, and hot liner <NUM>; and a film feeding device (not shown). When first die <NUM> and second die <NUM> are clamped, as shown in <FIG>, projection portion <NUM> enters recess portion <NUM>, and cavity <NUM> is formed between projection portion <NUM> and recess portion <NUM>. Fine uneven shape <NUM> is formed on the surface of projection portion <NUM>. Transfer film <NUM> is formed such that base film <NUM> (see <FIG>) faces fine uneven shape <NUM> and adhesive layer <NUM> (see <FIG>) faces recess portion <NUM> of second die <NUM>.

First, as shown in <FIG>, transfer film <NUM> is fed by the film feeder to be positioned between first die <NUM> and second die <NUM>. Thereafter, as shown in <FIG>, transfer film <NUM> is sandwiched and fixed between first die <NUM> and second die <NUM>. When transfer film <NUM> is sucked with vacuum pump <NUM> via suction hole <NUM> of first die <NUM>, transfer film <NUM> is caused to be in close contact with projection portion <NUM>. Resin <NUM> is poured into cavity <NUM> from spool <NUM> of second die <NUM> through hot runner <NUM>.

Thereafter, poured resin <NUM> solidifies and forms transmissive substrate <NUM> as shown in <FIG> and <FIG>, and adheres to adhesive layer <NUM>. Finally, hard coat layer <NUM> and peelable layer <NUM> shown in <FIG> are separated from each other by separating first die <NUM> and second die <NUM>. Accordingly, cover component <NUM> of the present embodiment is completed.

At this time, fine uneven shape <NUM> of projection portion <NUM> is transferred to hard coat layer <NUM> via base film <NUM> and peelable layer <NUM>. According to the manufacturing method, it is possible to obtain cover component <NUM> to which hard coat layer <NUM> having fine uneven shape 46a, decorative layer <NUM>, and the like are transferred at the same time as forming transmissive substrate <NUM>.

<FIG> is an enlarged sectional view of fine uneven shape <NUM> of projection portion <NUM> of first die <NUM>. Two-steps of uneven shapes which are first uneven shape <NUM> and second uneven shape <NUM> are formed. That is, first uneven shape <NUM> is provided on the surface of projection portion <NUM>, and second uneven shape <NUM> is provided on the surface of first uneven shape <NUM>. In order to form such two-steps of uneven shapes, the following sand blasting method is exemplified.

When projecting glass bead <NUM> having a large diameter such as #<NUM> (average particle diameter of <NUM>) to #<NUM> (average particle diameter of <NUM>) to projection portion <NUM>, first uneven shape <NUM> having an arithmetic average roughness (Ra) of approximately <NUM>, a root mean average roughness (Rms) of approximately <NUM> can be formed on the surface of projection portion <NUM>. Thereafter, when projecting glass bead <NUM> having a small diameter such as #<NUM> (average particle size of <NUM>) to #<NUM> (average particle size of <NUM>) to projection portion <NUM>, second uneven shape <NUM> having a root mean average roughness (Rms) of approximately <NUM> can be formed on the surface of first uneven shape <NUM>.

In addition to the sand blasting method using glass beads, it is possible to form a similar fine multistage uneven shape by using etching, electroforming plating, or the like. Examples of a measuring device of such two-step uneven shapes include a laser microscope and a surface roughness measuring machine.

Although cover component <NUM> of the present embodiment adopts an aspect in which decorative layer <NUM> having colored region <NUM> is provided immediately below hard coat layer <NUM> having anti-reflection region <NUM>, the cover component of the present embodiment is not limited to the aspect. For example, even in an aspect in which decorative layer <NUM> is provided below transmissive substrate <NUM>, it is possible to achieve the object. In this case, transfer film <NUM> does not include decorative layer <NUM>, and decorative layer <NUM> can be formed by forming transmissive substrate <NUM> by an insert forming method and then printing on transmissive substrate <NUM>.

Hereinafter, cover component of Embodiment <NUM> will be described with reference to <FIG>. In cover component <NUM> of the present embodiment, a surface of anti-reflection region <NUM> includes two kinds of fine uneven shapes 46b and 46c. Each of the two kinds of fine uneven shapes 46b and 46c has a different arithmetic average roughness (Ra) and a different root mean average roughness (Rms).

For example, in a case where the display panel is used in an inside of a vehicle, sunlight or the like is likely to be incident on a top of the display panel and may not easily enter a lower part. In this manner, in a case where the external light incident on the display panel is biased, when reducing the arithmetic average roughness and the root mean average roughness of the fine uneven shape where light is likely to be incident, it is possible to reduce diffusion of external light to prevent white blur in the screen from occurring.

In a case where the external light is likely to be incident on the top of the display panel as in the above example, the arithmetic average roughness (Ra) of fine uneven shape 46b of an upper part may be set to be smaller than the arithmetic average roughness (Ra) of fine uneven shape 46c of the lower part and the root mean average roughness (Rms) of fine uneven shape 46b of the upper part may be set to be smaller than the root mean average roughness (Rms) of fine uneven shape 46c the lower part.

As numerical values of the arithmetic average roughness (Ra) and the root mean average roughness (Rms), for example, in fine uneven shape 46b of the upper part, the arithmetic average roughness (Ra) is more than <NUM> and less than <NUM> and the root mean average roughness (Rms) is more than <NUM> and less than <NUM>. In fine uneven shape 46c of the lower part, the arithmetic average roughness (Ra) is more than <NUM> and less than <NUM> and the root mean average roughness (Rms) is more than <NUM> and less than <NUM>.

Although in an aspect shown in <FIG>, fine uneven shape 46b of upper part and fine uneven shape 46c of the lower part are provided, the present embodiment is not limited to the aspect. For example, according to a use of the cover component, in a case where the external light is biased in a right and left direction, the above effect can be obtained by disposing two kinds of fine uneven shapes on the left and right. In addition, considering the biasing of the external light, disposition of fine uneven shapes should be considered.

Although the present embodiment adopts an aspect in which two kinds of fine uneven shapes 46b and 46c are provided, the cover component of the present embodiment is not limited to the aspect, and may adopt an aspect in which three or more kinds of the fine uneven shapes each of which has a different arithmetic average roughness (Ra) and a different root mean average roughness (Rms) are provided.

Next, a manufacturing apparatus and a manufacturing method of cover component <NUM> of the present embodiment will be described with reference to <FIG>. Since approximate configurations of the manufacturing apparatus are the same as the configurations described with reference to <FIG> and <FIG> in Embodiment <NUM>, descriptions of the same configurations will be omitted. In the present embodiment, a sectional shape of fine uneven shape <NUM> of projection portion <NUM> of first die <NUM> is different from the shape of fine uneven shape <NUM> in Embodiment <NUM> described with reference to <FIG>.

<FIG> is a schematic sectional view of fine uneven shape <NUM> of projection portion <NUM> of first die <NUM>. Fine uneven shape <NUM> includes two kinds of fine uneven shapes 24a and 24b. <FIG> is a simplified schematic vies of fine uneven shapes 24a and 24b. A more detailed shape of fine uneven shape 24a is shown in <FIG>, and a more detailed shape of fine uneven shape 24b is shown in <FIG>. As shown in <FIG>, these two kinds of fine uneven shapes 24a and 24b are respectively configured of two-steps of uneven shapes which are a first uneven shape and a second uneven shape. In order to form such two-steps of uneven shapes, the following method is exemplified.

First, when projecting glass bead 31a having a large diameter of #<NUM> to a portion of projection portion <NUM> as shown in <FIG>, first uneven shape 32a having the arithmetic average roughness (Ra) of approximately <NUM>, the root mean average roughness (Rms) of approximately <NUM> can be formed on the surface of projection portion <NUM>.

Thereafter, when projecting glass bead 31b of #<NUM> to a position where first uneven shape 32a of projection portion <NUM> is not formed as shown in <FIG>, first uneven shape 32b having the arithmetic average roughness (Ra) of approximately <NUM>, the root mean average roughness (Rms) of approximately <NUM> can be formed on the surface where first uneven shape 32a of projection portion <NUM> is not formed.

When projecting glass bead <NUM> having a small diameter such as #<NUM> to #<NUM> on a whole projection portion <NUM> as shown in <FIG>, second uneven shape <NUM> having a root mean average roughness (Rms) of approximately <NUM> can be formed on the surfaces of first uneven shapes 32a and 32b.

That is, Embodiment <NUM> adopts an aspect in which one kind of first uneven shape <NUM> is provided on the surface of projection portion <NUM> as shown in <FIG>, whereas in Embodiment <NUM>, two kinds of fine uneven shapes 46a and 46b (see <FIG>) are provided on the surface of anti-reflection region <NUM> of cover component <NUM>. Therefore, as shown in <FIG>, two kinds of first uneven shapes 32a and 32b are also provided on the surface of projection portion <NUM> of the manufacturing apparatus.

<FIG> is a plan view of a cover component of Embodiment <NUM>. <FIG> is a side sectional view of the cover component. Hereinafter, the detailed description of the same configurations as the configurations in Embodiment <NUM> will be omitted, and only different points will be mentioned.

Cover component <NUM> of Embodiment <NUM> includes chromaticity adjustment layer <NUM> between hard coat layer <NUM> and decorative layer <NUM>. A thickness of chromaticity adjustment layer <NUM> is formed to be several µm. Chromaticity adjustment layer <NUM> contains a very small amount of yellow coloring agent (pigment or dye).

In general, due to deterioration over time of the cover component, the light diffusing in fine uneven shape 46a of the surface of anti-reflection region <NUM> is more likely to be reflected as the wavelength is shorter. Therefore, light having a short wavelength, such as blue light enters eyes of the viewer. Accordingly, a blue tinge appears. On the other hand, in the present embodiment, since chromaticity adjustment layer <NUM> containing a yellow coloring agent is provided, even if the blue light is likely to be reflected by the deterioration over time of the cover component, chromaticity adjustment layer <NUM> supplements the yellow tinge, so that tinges of colors can be canceled each other. Therefore, even if the cover component deteriorates over time in places where irradiation of external light is strong, such as inside the vehicle or mobile device, it is possible to maintain neutral color tone.

In addition, chromaticity adjustment layer <NUM> preferably contains a UV absorber in addition to the yellow coloring agent. According to the aspect, the UV (ultraviolet) absorber improves the weather resistance of underlying transmissive substrate <NUM> or the display panel itself, and can prevent a molecular complex of the resin from being attacked by ultraviolet light. Therefore, it is possible to prevent a light absorption band of the resin from being shifted to a longer wavelength side due to deterioration over time and absorbing in a blue region. It is possible to further maintain the neutral color tone.

Although, in <FIG>, an aspect in which single kind of fine uneven shape 46a is provided on the surface of hard coat layer <NUM> is illustrated, the cover component of the present embodiment is not limited to the aspect. That is, as in Embodiment <NUM>, an aspect in which two or more kinds of fine uneven shapes are provided on the surface of the hard coat layer <NUM> may be adopted.

<FIG> and <FIG> show an example of transfer film 53a used for manufacturing cover component <NUM> of the present embodiment. Unlike transfer film <NUM> described in Embodiment <NUM>, chromaticity adjustment layer <NUM> is provided between hard coat layer <NUM> and decorative layer <NUM>. Chromaticity adjustment layer <NUM> is also formed by vacuum film formation, gravure printing, screen printing, ink jet printing, or the like. Since a manufacturing apparatus and a manufacturing method of cover component <NUM> are the same as the manufacturing apparatus and the manufacturing method of Embodiment <NUM>, a detailed description will be omitted.
