Abstract

PROBLEM TO BE SOLVED: To provide a display panel having designs to offer double amusement by changing ordinary patterns and the patterns of the nighttime or a dark place as ornaments to emit light with the dials of timepieces and various other meters and other display panels and to provide a display panel having the designs to attract people's attention. SOLUTION: A transparent film 1 is subjected to negative woodgrain tone printing 3 and black printing 7, then to white printing 5 thereon, followed by positive woodgrain tone printing 2 so as to make the printing normally visible. This display panel has the woodgrain tone patterns when viewed in the daytime or with natural light but turns to the display panel which emits the light to provide uniformly flush emitted light only at the points where there is no black printing 7 in the nighttime or the dark place or with the transmitted light of an internal light source. As a result, the display panel which offers the double amusement in spite of the same object as there is a difference between the visible way in the daytime and the visible way in the nighttime or the dark place and which has the designs to attract the people's attention by letting people to think 'what ?' may be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

This invention can be used for clocks, other dials of various instruments, and other applications where it is desired to enhance the design by replacing the normal pattern as a decorative product that emits light on a printed display panel with the pattern at night or in a dark place. It is about the method.

[0001]

[Industrial applications] Clocks, other dials of various instruments, and other decorative items that emit light on printed display panels, changing the design at night or in dark places to enhance the design Sometimes this can be widely used.

[0002]

2. Description of the Related Art For example, there are various printed display panels, such as a lantern and a symbol for a side brake of an automobile meter, which are usually plain but display a pattern when an internal light source is turned on. As a result, there is no printed display panel having a portion that makes the pattern invisible and emits a uniform surface light, or a portion or a design that emits a uniform surface light.

[0003]

When the internal light source is turned on, the pattern becomes invisible and emits a uniform surface light, or a printed display panel having a portion or a design that emits a uniform surface light is made attractive. It is something that tries to create a design.

[0004]

Means for Solving the Problems A transparent film or sheet is subjected to a printing in which the shade of a normally visible pattern is replaced to make it a complementary color, hereinafter referred to as negative printing, and a solid printing such as white is performed thereon, and then the printing is performed. A normally visible pattern is printed on the top, hereinafter referred to as positive printing. Or
Negative printing is performed on the back side of the transparent film or sheet, solid printing such as white is performed on the front side, and then positive printing is performed thereon. Alternatively, white or the like is printed on the back side of the transparent film or sheet, and then negative printing is performed, and positive printing is performed on the front side. Alternatively, positive printing is performed on the front side of a white film or sheet, a cloudy resin plate, a smoke resin plate, or a half mirror, and negative printing is performed on the back side. By such a method, when viewed with natural light in the daytime, it is a printed display panel with a pattern, but at night or in a dark place, the light emitted by the internal light source emits uniform surface light, or a uniform surface is emitted. It becomes a printed display panel with a part that emits light and a design. For example, by printing a light-impermeable print that does not allow the light from the internal light source to pass through and creating a shadow area so that only the figures and design parts can transmit light, usually only the pattern can be seen. In particular, a printed display panel that emits surface light with uniform numbers and designs can be obtained.
Depending on the color tone of the positive printing, solid printing such as white that enters between negative printing and positive printing, a white film or sheet, a cloudy resin plate, a smoke resin plate, and a half mirror need to be appropriately selected. It is necessary to appropriately adjust the density of the negative printing depending on the optical characteristics. Further, it is necessary to appropriately select the solvent of the printing ink depending on whether the half mirror is made of resin or glass, or the kind of the metal deposited. In some cases, a surface treatment is required so that the printing ink is applied.

[0005]

[Function] By having the structure as described in the preceding paragraph, there is a difference between the appearance in the daytime and the appearance in the night or in the dark, so that it is possible to make a printed display panel with a design that can be enjoyed twice while being the same. Was.

[0006]

[Examples]

As shown in FIG. 1, a negative woodgrain print (3) is applied to the design portion (2) or the whole of the transparent film (1), and a black print (7) is applied to the non-design portion (4) because of the light impermeability. ) After which a light white print (5) is applied over the entire surface, and then a positive woodgrain print (6) is applied thereon as normally seen. In the daytime, when viewed with natural light, it is a printed display panel with a woodgrain pattern, but at night or in a dark place, the printed part emits light that makes the design part (2) have uniform surface emission in the transmitted light of the internal light source. Become a panel.
In the embodiment, only the design portion (2) emits uniform surface light. However, it is also possible to emit uniform surface light as if all the patterned surfaces were plain by turning on the internal light source.

FIG. 2 is a photograph of the woodgrain design used in the preparation of the example.

FIG. 3 is a negative photograph thereof. It is actually a color design

FIG. 3 shows four color separations for each of four steps of silk printing.

[0007]

By providing the structure as described in the preceding paragraph, since there is a difference between the appearance in the daytime and the appearance in the nighttime or in a dark place, a printed display panel having a design that can be enjoyed twice while being the same thing is provided. Was completed. Also, by making them think "Oh?", They were able to make printed display panels with eye-catching designs.

Claims (1)

[Claims] 1. A pattern is usually visible on the surface of a printed display panel. However, when the inside of the printed display panel is turned on at night or in a dark place, the pattern is not visible, and uniform surface light emission is obtained. A method for producing a printed display panel that emits light, characterized in that the surface emits a light-emitting portion or a pattern with a design.
