BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. 1 is a flow chart of a method of processing a stealth display device in accordance with an embodiment of the present invention. Referring to FIG. 1, a method for processing a stealth display device according to an embodiment of the present invention includes the following steps: Step S102: Add a bottom layer on a pre-purpose display surface (as shown in FIG. 2). Preferably, the primer is pre-applied to a display device, such as a keyboard, a screen, an indicator light, etc., as a primer for the light opacity, and the primer may be one layer or multiple layers, and may be used in addition to spraying. Other surface treatment methods such as plating, the effect of adding the bottom layer is shown in Fig. 3, and the shading in the figure shows the effect of adding the bottom layer. Step S104: carving the content or area to be displayed on the bottom layer. Preferably, the desired content or area is carved on the bottom layer processed by the step S102, for example, the primer of the desired display content or the area portion is removed by engraving such as laser engraving on the bottom layer, and is carved out like a keyboard. The outer frame area of characters, indicators, screens, etc., the effect after carving is shown in Figure 4. Step S106: Add a surface layer on the bottom layer, and the surface layer has a lower light coverage rate than the bottom layer. Preferably, after step S104, a layer of lacquer is added to the ground layer after the carving. If it can be sprayed or applied, the top coat with a lower light coverage than the underlying primer is applied to the primer to form a surface layer. The effect after adding the surface layer is shown in Fig. 5. The shading in the figure shows the effect after adding the surface layer, and the visual effect is different from that of Fig. 3. According to the visual principle, when the backlight is not lit, only the reflected light of the topcoat can be seen, so that the desired content or area, such as characters, indicators and external patterns on the keyboard, cannot be seen, and the content to be displayed is realized. Or the invisibility of the area. In the case where the backlight is lit, since the surface layer has a lower light coverage rate than the bottom layer, the backlight can penetrate the surface layer from the underlying hollow portion, and the engraved character and content are displayed from the surface of the device, and the display effect when the backlight is lit is as follows. Figure 6 shows. Preferably, in order to protect the surface layer, a protective layer having a light shielding rate lower than that of the surface layer may be added to the surface layer. For example, the protective layer can be a transparent film. The processing method of the invisible display device of the present invention can realize the invisible shape of the display content or the area required for the display member in the unlit state of the backlight, thereby forming an overall effect, simple and low in cost, rich in color, and high in realization. Bright or *light effects to enhance the user experience. According to an embodiment of the invention, an invisible display device is further provided, comprising a bottom layer, the bottom layer is engraved with the desired display content, and the bottom layer is further provided with a surface layer, and the surface layer has a lower light coverage rate than the bottom layer. Preferably, the surface layer is further provided with a protective layer, and the protective layer has a lower light shielding rate than the surface layer. Preferably, the bottom layer is laser-engraved, and the corresponding surface layer may or may not have a protective layer. In a preferred embodiment, an invisible display device is provided that includes a bottom layer and a skin layer. The bottom layer is a primer that has a high light opacity. The bottom layer is covered with a surface layer. The surface layer is a top coat that has a lower light coverage than the bottom layer. The bottom layer can be engraved with different contents or areas to suit the needs. For example, characters or patterns can be carved, and the engraving can be done by laser engraving. The device provided in this embodiment can realize the invisible display content when the backlight is not lit. This device can be used in a variety of devices, such as keyboards, indicators, displays, and mobile terminals that use these devices. End. If the display device is disposed on the keyboard, the keyboard characters are engraved on the bottom layer. When the keyboard backlight is not lit, only the reflected light of the surface layer can be seen, the keyboard characters can not be seen, and the invisible shape is realized. When lit, since the surface layer has a lower light coverage rate than the bottom layer, the backlight can penetrate the surface layer from the hollow portion, and the engraved keyboard characters are displayed from the surface. The device can also be used on the indicator light. The shape of the outer frame of the indicator light is engraved on the bottom layer. When the indicator light is not lit, the indicator light is not visible. When the backlight is lit, the indicator light can be seen. The device can also be used on the screen. The shape of the outer frame of the screen is engraved on the bottom layer. When the screen is not lit, the presence of the screen is not visible. When the backlight is lit, the presence of the screen can be seen. There are also keyboards, indicators, screens, and mobile terminals, such as mobile phones, that contain invisible display devices. The invisible display device, the processing method thereof and the application device of the invention can make the display content of the component to be processed invisible when the backlight is not illuminated, thereby forming an overall effect, simple and low cost, rich in color, and can realize highlighting or * Light effects to enhance the user experience. The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention. Those skilled in the art should understand that the above embodiments are only for illustrating the present invention, and are not intended to be used in the present invention. It is to be understood that variations and modifications of the above-described embodiments are intended to fall within the scope of the appended claims.
