Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1, a simple display device mainly includes the following parts: the light-diffusing plate comprises a substrate 1, a light-diffusing plate 2 and a light strip 3, wherein the substrate 1 is provided with a plurality of different hollowed-out characters or patterns, the light-diffusing plate 2 is arranged on the back surface of the substrate 1, the light strip 3 is arranged on one side (two sides, three sides or even four sides) of the periphery of the light-diffusing plate 2, light emitted by the light strip 3 can enter the light-diffusing plate 2, and partial light can be emitted from the hollowed-out area of the substrate 1 after being refracted by the light-diffusing plate 2, so that the light-diffusing plate 2 is shielded from other parts except the hollowed-out area through the substrate 1, corresponding characters or patterns can be displayed, and if other patterns are required to be displayed, only the substrate 1 with other hollowed-out characters or patterns needs to be replaced.

In this embodiment, the substrate 1 is generally formed by processing a sheet metal part, so that different hollow characters or patterns can be processed conveniently, and the light emitted by the light strip 3 is monochromatic, so that the color displayed in the hollow area of the substrate 1 is also monochromatic.

Example 2

The difference between the embodiment 2 and the embodiment 1 is that the above-mentioned light strip 3 is composed of a plurality of LED lamps, and can emit light with different colors, and by changing the color of the light emitted by the LED lamps, the pattern or character color displayed in the hollowed-out area of the substrate 1 is also different, the incident direction of the light of the plurality of LED lamps is the direction of the light-diffusing plate 2, and after the light is injected into the light-diffusing plate 2, the light will be scattered continuously in the light-diffusing plate 2, and finally, after being refracted by the light-diffusing plate 2, the light is injected from the hollowed-out area of the substrate 1.

Example 3

Referring to fig. 2, the difference between embodiment 3 and embodiment 1 is that a color plate 5 is disposed between the light diffusion plate 2 and the substrate 1, or the color plate 5 may be disposed in the hollowed-out area of the substrate 1, and when the light source with pure color emitted by the light strip 3 enters the light diffusion plate 2, the light source is subjected to the diffusion treatment of the light diffusion plate 2, and after being refracted from the light diffusion plate 2, passes through the color plate 5 between the light diffusion plate 2 and the substrate 1, or passes through the color plate 5 in the hollowed-out area of the substrate 1, so that the characters or patterns displayed in the hollowed-out area of the substrate 1 may be different from the colors of the light source.

In this embodiment, the color plate 5 is replaceable, and may be a single color plate 5 with different colors, or may be a multi-color plate 5 with multiple colors (i.e. different positions of one color plate 5 display multiple different colors), if different colors are conventionally displayed, only the single color plate 5 between the light-diffusing plate 2 and the substrate 1 or the single color plate 5 in the hollowed-out area of the substrate 1 needs to be replaced by another color plate 5, so that other colors can be displayed, or the multi-color plate 5 with multiple colors is placed between the substrate 1 and the light-diffusing plate 2, so that different positions of the hollowed-out area of the substrate 1 can display different colors, and of course, different color plates 5 with different colors can be placed in different positions of the hollowed-out area of the substrate 1, so that the purpose of displaying different colors of characters or patterns can also be achieved.

Example 4

Referring to fig. 3, the difference between embodiment 4 and embodiment 1 is that a light reflecting mechanism 4 is disposed on a side of the light diffusing plate 2 away from the substrate 1, the reflecting surface of the light reflecting mechanism 4 is close to the light diffusing plate 2, and the light reflecting mechanism 4 may be light reflecting paper or a light reflecting plate, or a reflective mirror may be used, and since the light emitted from the light diffusing plate 2 is emitted in all directions, the light reflecting mechanism 4 is disposed on the back surface of the light diffusing plate 2, so that the light emitted from the back surface of the light diffusing plate 2 is reflected by the light reflecting mechanism 4 and then re-enters the light diffusing plate 2, and is refracted by the light diffusing plate 2 and then enters the hollowed-out area of the substrate 1, and brightness of characters or patterns displayed in the hollowed-out area of the substrate 1 can be improved.

As shown in fig. 4, the periphery of the light-diffusing plate 2 is further provided with an adhesive tape 6, the light-reflecting mechanism 4 is adhered to the back surface of the light-diffusing plate 2 (i.e. the side far away from the substrate 1) through the adhesive tape 6, the adhesive tape 6 can be arranged at the position where the lamp strip 3 is not arranged on the other sides of the light-diffusing plate 2, and the adhesive tape 6 can be opaque or reflective, because the light-diffusing plate 2 emits light up and down and front and back, after the light source in the light-diffusing plate 2 irradiates the adhesive tape 6, the opaque adhesive tape 6 can block light to prevent the light from being emitted, the reflective adhesive tape 6 can reflect the light to reenter the light-diffusing plate 2, and the purpose of the arrangement is to ensure that the light in the light-diffusing plate 2 is emitted only from one side deviated to the substrate 1, so as to improve the display brightness of the hollowed-out area on the substrate 1.

Example 5

Referring to fig. 5, embodiment 5 is different from the above embodiment in that the edge of the substrate 1 is bent back to wrap the diffusion sheet 2, the color sheet 5 and the lamp strip 3, so that the light emitted from the diffusion sheet 2 is blocked by the edge of the substrate 1, preventing the light from being emitted to the outside area.

The above technical solution only represents the preferred technical solution of the present utility model, and some changes that may be made by those skilled in the art to some parts of the technical solution represent the principles of the present utility model, and the technical solution falls within the scope of the present utility model.
