Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of camera aperture filters, and in particular to a cover plate with a camera aperture filter. Background Technology
[0002] Currently, existing smart display cover plates are all pursuing an all-black design. However, because holes for cameras need to be made in the cover plate, the color around the camera hole will differ from other areas, thus affecting the overall visual appeal. Therefore, a cover plate with a camera hole filter is designed to achieve a switch between all-black and light-transmitting areas in the camera hole area, allowing the area around the camera hole on the cover plate to form an overall all-black effect, thereby improving product competitiveness. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cover plate with a camera aperture filter.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A cover plate with a camera aperture filter includes: a cover plate having a camera aperture and a filter on the surface of the camera aperture; the cover plate is disposed on the front of a display module, which includes a controller and a power supply; the controller and the power supply are electrically connected to the filter via wires.
[0006] In one embodiment, the front of the camera hole is circular, and the camera hole is located at the top center of the front of the cover plate.
[0007] In one embodiment, the front of the filter is circular, and the diameter of the front of the filter is the same as the diameter of the front of the camera aperture.
[0008] In one embodiment, the filter is made of electrochromic glass and is attached to the surface of the camera aperture.
[0009] In one embodiment, an electric coil is disposed around the filter, the electric coil being connected to the filter and electrically connected to the controller.
[0010] In one embodiment, the controller includes a power-on module for powering the filter when the camera function is enabled.
[0011] In one embodiment, the four corners of the cover plate are rounded.
[0012] In one embodiment, the wires between the filter and the controller are arranged around the edge of the central display screen of the cover plate.
[0013] In one embodiment, the controller is a PCB circuit board.
[0014] In one embodiment, the filter is disposed on the side of the cover plate near the display screen.
[0015] Compared with the prior art, the present invention has at least the following advantages:
[0016] This utility model discloses a cover plate with a camera aperture filter. Through the positional relationship between the filter and the camera aperture, the filter can cover the camera aperture. At the same time, through the circuit design between the controller, power supply and filter, the filter is only powered on when the customer needs to use the camera function, making it light-transmitting and able to take pictures normally; when the camera function is not used, the filter is de-powered, achieving a completely black effect. Together with the other areas of the cover plate, it forms a unified black effect, improving the product's competitiveness. Attached Figure Description
[0017] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0022] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0023] Unless otherwise explicitly specified and limited, the terms “installation,” “connection,” “linking,” “fixing,” etc., should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0025] like Figure 1-2 As shown, a cover plate with a camera aperture filter includes: a cover plate 1, a camera aperture 2 on the cover plate 1, and a filter 3 on the surface of the camera aperture 2; the cover plate 1 is disposed on the front of a display module, which includes a controller 4 and a power supply 5; the controller 4 and the power supply 5 are electrically connected to the filter 3 via wires. It should be noted that the non-display areas of the cover plate 1 are coated with black ink.
[0026] like Figure 1-2 As shown, in one embodiment, the front of the camera hole 2 is circular, and it is located at the top center of the front of the cover plate 1. The front of the filter 3 is also circular, and its diameter is the same as that of the camera hole 2. It should be noted that the shape and size of the camera hole 2 are designed according to different needs. While its shape is mostly circular, its size is not always the same, and its position on the cover plate 1 is not always identical.
[0027] like Figure 1-2 As shown, in one embodiment, the filter 3 is made of electrochromic glass and is attached to the surface of the camera aperture 2. It should be noted that the electrochromic glass transmits light when an electric current is applied, and appears black when no current is applied.
[0028] like Figure 1-2 As shown in one embodiment, an electric coil is arranged around the filter 3, and the electric coil is connected to the filter 3 and also electrically connected to the controller 4. The controller 4 includes a power-on module, which powers the filter 3 when the camera function is activated. The controller 4 is a PCB circuit board. It should be noted that when the user uses the product, the power-on module allows electricity from the power supply 5 to flow into the filter 3, energizing it and making it transparent, thus not affecting the normal operation of the camera module.
[0029] like Figure 1-2 As shown in one embodiment, the four corners of the cover plate 1 are rounded. The wires between the filter 3 and the controller 4 are arranged around the edge of the central display screen of the cover plate 1. It should be noted that this design ensures that the wires do not affect the normal display of the screen.
[0030] like Figure 1-2 As shown in one embodiment, the filter 3 is disposed on the side of the cover plate 1 near the display screen.
[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
