Description

  The present invention relates to a display panel provided with a reflection means by natural light and incident light of an LED.

  A display panel previously filed by the present applicant, i.e., a groove for forming characters, symbols, patterns, etc. is formed on one side of a transparent synthetic resin substrate, and a base layer made of a transparent acrylic resin is formed on the bottom of the groove, The surface of the underlayer is an intermediate layer formed by mixing a fine resin piece and transparent resin, which are chopped by sandwiching a colored aluminum foil between two thin transparent films and having a thickness of about 0.2 mesh to 0.5 mesh. Further, a pressure plate made of a transparent resin is further laminated on the surface of the intermediate layer sequentially in a semi-dry state and solidified, and the display plate is used as a display plate main body, and a colored synthetic resin plate is further provided on the back surface thereof. A display panel (see, for example, Patent Document 1) to which is attached is known.

Japanese Utility Model Publication No. 6-23074

  The display plate according to Patent Document 1 has a configuration in which minute strips (hereinafter referred to as brilliant minute pieces) having a reflective surface having a metallic luster are kneaded into a resin layer, so that the color of reflected light depends on how light strikes. This reveals a pattern that changes, and a certain effect can be obtained.

However, although it has bright fine pieces that change the color of the reflected light, it is used only with natural light without using a phosphorescent paint or backlight, so it is difficult to obtain enough reflected light. In order to obtain reflected light, an extremely large amount of bright fine pieces was used.
In reality, it is difficult to obtain sufficient reflected light even when a very large amount of bright fine pieces are used.

  Moreover, since each of the bright fine pieces was kneaded so as to be surrounded by a thick resin, it was further difficult to obtain sufficient reflected light.

The present invention has been made in view of the above circumstances, and a second reflecting portion is formed on a multilayer plate in which a transparent layer and an opaque layer are formed in a laminated state, and a first reflecting member is polymerized thereon. By making LED light incident from a part of the outer peripheral edge of the display panel or from the entire periphery of the outer peripheral edge, the glittering fine pieces in which the color of reflected light changes between natural light and LED light further increase in brightness, and even in dark places. The display part such as letters, figures, and patterns of the second reflecting part formed of fine pieces is combined with the reflected light of natural light and the incident light of LED light to make the second reflecting part further shine, and a small amount Strong reflected light can be obtained with the bright fine pieces.
Since the second reflecting portion can obtain very strong reflected light by the incidence of LED light, it can be used in places where natural light is weak and at night, as well as indoors and outdoors, display display boards, road markings, The idea is to provide a display board that can be used for information boards, signboards, display boards for advertising, character display boards for ranks, nameplates, and tombstones, as well as information displays for floors, walls, and stairs. It is set as a subject.

  According to the present invention, a multilayer plate 1 in which a transparent layer 10 and an opaque layer 11 are formed in a laminated state, a part of the transparent layer 10 is left from the opaque layer 11 to the transparent layer 10 of the multilayer plate 1 to be described later. A groove-like recess 13 serving as a display portion is cut and formed, and a plurality of bright fine pieces 14 having a reflecting surface in the recess 13 are dispersed in an average and irregular orientation in the direction of the reflecting surface. The coating is applied to fix the glittering fine pieces 14 to form the second reflecting portion 15 having the display portions 12 such as characters, figures and patterns, and on the back side of the multilayer board 1 having the second reflecting portions 15. A display substrate S formed by superposing and fixing the first reflecting member 2 is formed, and the entire circumference of the outer peripheral edge 3 of the display substrate S is not covered with the reflective tape 5 or is covered with the reflective tape 5 leaving a part, A plurality of LEDs 4 are arranged outside the outer peripheral edge 3 at a portion not covered with the reflective tape 5 It covers the entire rim 3 with a covering member 5A to a display board made equipped with electric circuit switchgear to the LED 4, the means for solving the problems.

  According to the present invention, when light is incident from the front surface side, the light is reflected in an irregular direction by the second reflecting portion 15 near the front surface side, and further, LED is emitted from an unshielded portion of the outer peripheral edge 3 of the display substrate S. In addition to the incident light, linear light and a diffused light source are incident, and part of the light that has further entered the interior through the gap formed in the second reflecting portion is absorbed and reflected by the colored paint layer and further transmitted through the colored paint layer. The reflected light is reflected by the first reflecting member 2, and a part of the reflected light is emitted to the outside with a colored wavelength, thereby causing irregular irregular reflection of the second reflecting portion 15 and the second reflecting portion. Reflected light from 15 gaps is obtained in color. On the other hand, although the second reflecting portion 15 is in a dispersed state in plan view, the second reflecting portion 15 is positioned on the transparent underlayer of the recess 13 as a whole, so that the direction of the reflecting surface is irregular on the plane of the transparent underlayer. Since the portions are partially overlapped and dispersed on average, the second reflecting portion 15 is densely reflected as a whole. Due to the synergistic effect of these reflections and the incident light by the LED light from the outer peripheral edge 3 of the display substrate S, that is, the second reflection part 15 is very dark even when the second reflection part 15 is dark due to the reflected light from the surface side and the incident light of the LED light Therefore, it is possible to obtain a display portion 12 such as a character, a figure, or a pattern that is strong against light and has irregularly strong reflected light due to irregular reflection.

Alternatively, a part of the reflective film 11C of the multilayer plate 1B is scraped off with a blade, and a scraped recess 13D is formed on the reflective film surface to be a display portion 12B described later, and the bright fine piece 14 having a reflective surface in the scraped recess 13D. After the ink is applied to the area by screen printing or textile printing with the ink 14A having a fine fine particle mixed with the coloring agent, and the ink of the part is dried and fixed, the display part 12B such as the character, figure, pattern or the like is formed. Forming the second reflecting portion 15 and forming the display substrate S5 by polymerizing and fixing the first reflecting member 2 on the back surface side of the multilayer board 1B on which the second reflecting portion 15 is formed,
The entire outer peripheral edge 3 of each display substrate S4, S5 is not covered with the reflective tape 5 or is covered with the reflective tape 5 leaving a part, and a plurality of portions are not covered with the reflective tape 5 on the outer peripheral edge 3. The LED 4 is disposed and the entire outer peripheral edge 3 is covered with a covering 5A, and the LED 4 is equipped with an electric circuit switching device, and the LED is irradiated from the outer peripheral edge to display the second reflecting portion 15 clearly. It is a manufacturing method of the display board to be taken as.
Since the ink 14A with glittering fine pieces mixed with the colorant is printed and applied to the groove-like recess 13C or the shaving recess 13D, the second reflecting portion 15 having the display portion 12B such as the characters, figures, patterns, etc. is formed. The multilayer plate 1B having the second reflecting portion 15 can be mass-produced, and the usage is widened at a low price.
The first reflecting member 2 is superposed and fixed on the back surface side of the second reflecting portion 15 to form the display substrate S5, and the entire outer peripheral edge 3 of the display substrate S5 is not covered with the reflecting tape 5 or a part thereof is left. A plurality of LEDs 4 are arranged in a portion that is covered with the reflective tape 5 and not covered with the reflective tape 5 on the outer peripheral edge 3, and the entire outer peripheral edge 3 is covered with the covering body 5 </ b> A. It is possible to manufacture a display board that is equipped with an LED and irradiates the outer periphery with LEDs.
In addition, an electric circuit switching device was used so that it was blinked by a battery and an LED illuminant when it was embedded in a pot, a tombstone, a wall surface, a floor surface or the like.

  Further, the light further transmitted by mixing the colored fine paint with the glittering fine piece is reflected by the first reflecting portion 2, and a part of the reflected light is emitted only in the wavelength of the colored color outward. Irregular diffusely reflected light of the bright fine pieces 14 and colored reflected light reflected from the first reflecting member 2 through the colored paint and emitted from the gaps between the bright fine pieces 14 are obtained.

  Further, as described above, the color paint is exposed to the inside of the concave portion 13 of the second reflecting portion 15 and directly from the gap between the bright fine pieces 14, so that the color of the paint becomes clearer and visually The effect can be improved.

  Further, although the glittering fine pieces 14 of the second reflecting portion 15 are in a dispersed state in plan, the transparent base of the transparent layer in the concave portion of the transparent layer is configured to be densely positioned on the transparent base of the concave portion 13 as a whole. In the above, since the direction of the reflecting surface is irregular, it is partially polymerized and dispersed on average, so that the bright fine pieces 14 are closely reflected as a whole. By reflecting the incident light, brighter reflected light can be obtained.

  Due to the synergistic effect of the above action, the display portion 12 shines brightly by the irregular reflection having a very strong brightness and the irregular reflected light by the incident light of the LED 4 from the outer peripheral edge 3 by the incidence of light from the surface side. It can be done.

Moreover, since the reflective surface of the brilliant fine piece 14 is a substantially hexagonal piece, the reflected light from the corners reaches the eye, and the outline of the reflected state is compared with the case of the circular brilliant fine piece 14. Becomes clearer, and it is possible to obtain reflected light having an outline shape with sharp corners of the reflecting surface.
In addition, since the reflecting surface is a substantially hexagonal piece, the side surface is formed as a six-sided flat surface, so that these act as a reflecting surface independent from the incident light of the LED, so that the bright fine piece The brightness of 14 itself can be remarkably improved.

Next, a method for manufacturing the display substrate S according to Example 1 will be described.
First, as shown in FIG. 1, characters, patterns, figures and symbols are formed on the back side of a multilayer board 1 formed by applying an opaque urethane baking coating having a thickness of less than about 0.1 mm on the back side of an acrylic resin transparent board. For example, a desired design is formed, and a corresponding groove is formed to a depth of 0.1 to 0.2 mm. (In FIG. 2, for easy understanding, the thickness ratio is appropriately changed and displayed, for example, by increasing the film thickness of the urethane baking coating portion (that is, the opaque layer).)

  Next, a supernatant of a colorless and transparent transparent varnish is applied to the bottom of the recess 13, the glittering fine pieces 14 having a reflective surface are dispersed from above, and a colored paint is applied to the part. After the colored paint is dried, The transparent layer 10 and the opaque layer 11 are formed. The upper part of the second reflecting portion 15 is formed as a substantially horizontal flat surface, and the bright fine pieces 14 as the second reflecting portion 15 are spread on the flat surface on average to form the second reflecting portion 15.

  And a coloring agent is apply | coated with respect to the said brightness | luminance fine piece 14, and a colored coating material is apply | coated. Here, Conxten (trade name) manufactured by Washin Paint is used as the colorant in the present embodiment, and a brush is used for coating.

Of course, the colorant is not limited to the complex as shown as an example, and various known colorants can be used, and various colors can be used in combination.
Moreover, also about the coating method, various well-known coating means other than brushes, such as spraying, can be utilized, for example.

  After drying the colorant, a double-sided adhesive tape or adhesive except for the opening of the recess 13 (that is, the part coated with the colorant) on the back side of the multilayer board 1 that accommodates the bright fine pieces 14 Then, the aluminum plate as the first reflecting member 2 is superposed and fixed.

  Next, the support plate 6 is bonded to the back surface side of the aluminum plate which is the first reflecting member 2 using an adhesive, and the outer periphery 3 of the multilayer plate 1, the first reflecting member 2 and the support plate 6 are arranged on the entire periphery and outside. Covering part 5 </ b> A using an adhesive with respect to the entire support plate 6 exposed to the back side by allowing the light of the LED 4 to be incident from the outer peripheral edge that is not covered and leaving a part of the periphery. Cover and complete.

  Moreover, although the 1st reflection member 2 in this invention was made into the aluminum plate in the said Example 1 and Example 2, this invention is not restricted to this, For example, it can also be set as the plate-shaped body etc. which have a mirror surface. In addition, a soft film in which a metal film is formed by vapor deposition can be used.

Furthermore, the multilayer board or the transparent board and the opaque board do not necessarily have to be hard, and the synthetic resin film-like thin film or the like is formed on a soft transparent layer or a soft transparent board of nylon, fluororesin, or polypropylene. As described above, an opaque layer or an opaque plate formed as a soft material can be laminated.
For example, as described above, the display substrate can be formed to be soft by combining the first reflective member as a reflective member such as a soft film.
Note that soft means not only an elastic material but also a flexible material.

  The above-mentioned display board according to the present invention uses LED light, regardless of whether it is hard or soft, in addition to signboards, decorative boards and nameplates, road signs, vehicle license plates, night safety reflectors, nighttime It can also be used as a safety reflective tape or the like, or it can be used as a bird extermination tool in a field or the like to give a visual effect by diffused light by flying with the wind.
