Please refer to FIG. 1, FIG. 2 and FIG. 3. In which, FIG. 1 is a three-dimensional schematic diagram of the electronic device 100 provided in the first embodiment of the application, and FIG. 2 is another perspective view of the electronic device 100 provided in the first embodiment of the application. A three-dimensional schematic diagram, FIG. 3 is a side cross-sectional view of the electronic device 100 according to Embodiment 1 of the application. In this embodiment, the electronic device 100 includes a transparent casing 10 and an electronic device 20. Specifically, the transparent housing 10 is made of transparent materials, such as glass, plastic, etc. In one embodiment, the transparent housing 10 is colorless. In other embodiments, the transparent housing 10 may also have a certain color or pattern. . In this embodiment, the transparent casing 10 is roughly a rectangular parallelepiped shape. On the one hand, it is convenient to install the electronic device 20 and the transparent touch film 30 inside, and on the other hand, it is convenient for the user to hold and operate the transparent touch film 30.

Specifically to FIG. 3, in this embodiment, the transparent housing 10 includes a first surface 102 and a light guide surface 104 disposed on the first surface 102. The light guide surface 104 can refract light so that the light avoids the interior of the transparent housing 10. The light-shielding area 12 is formed, and the light-shielding area 12 is an area avoided by the propagation route of light. Specifically, the first surface 102 is an end surface of the transparent casing 10.

Please continue to refer to FIG. 3, in this embodiment, the electronic device 20 is arranged in the light-proof area 12. Specifically, the electronic device 20 may be housed in the cavity formed by the transparent housing 10 corresponding to the light-proof area 12. When viewing the electronic device 100 within a certain angle range above the device 100, the electronic device 20 is not visible. In one embodiment, the electronic device 20 may be a circuit board, a battery, or the like.

In this embodiment, the light incident on the light guide surface 104 is deflected by the light guide surface 104 in a direction away from the light-shielding area 12 into the transparent casing 10. The light entering the transparent housing 10 from the side opposite to the light guide surface 104 enters the side surface of the light-shielding area 12, and is totally reflected by the side surface of the light-shielding area 12 and exits the transparent housing 10. The light guide surface 104 and the light-proof area 12 are recessed toward each other. Specifically, please refer to FIG. 4. FIG. 4 is a schematic diagram of the optical path when the line of sight is perpendicular to the first surface 102. Specifically, FIG. 4 is a schematic diagram of the optical path of light exiting or entering the transparent casing 10 perpendicular to the first surface 102. As shown in the figure, since the refractive index of the air is different from that of the material of the transparent casing 10, when the light passes through the light guide surface 104, the light is refracted, and the propagation path of the light is shifted, and the shifted light cannot The light-shielding area 12 is formed in the area passing through or unable to travel.

Please continue to refer to FIG. 4, in this embodiment, when the user's eyes are directly above the light guide surface 104, the user receives light emitted in a direction perpendicular to the first surface 102, because the light occurs when passing through the light guide surface 104 Refraction, so that the propagation path of the light does not pass through the light-shielding area 12. Therefore, the user cannot see the structure in the light-shielding area 12, that is, the light-shielding area 12 forms a visual blind zone. Further, the user can see through the transparent housing 10 the scene on the side of the transparent housing 10 away from the user’s eyes. In other words, when the user observes the electronic device 100 from directly above the light guide surface 104, the user cannot see The electronic device 20 and the electronic device 100 in the light area 12 have a completely transparent structure in the eyes of the user.

Please refer to FIG. 5, which is a schematic diagram of the light path when the line of sight and the first surface are at an angle α1.

The cavity may be vacuum, filled with air, or filled with other refractive indices. A material having a refractive index smaller than that of the transparent casing 10. When the user’s eyes are located above the first groove 42 and obliquely observe the transparent housing 10 at a first angle α1, the user receives light that is at a first angle α1 to the thickness direction of the transparent housing 10, and the light is transmitted to The boundary surface of the cavity formed by the light-shielding area 12 is totally reflected, so that the propagation path of the light does not enter the light-shielding area 12, so the user cannot see the structure in the light-shielding area 12, that is, the light-shielding area 12 Form a blind spot of vision. Further, the user can see through the transparent housing 10 the scene on the side of the transparent housing 10 away from the user’s eyes. In other words, when the user observes the electronic device 100 within a certain tilt angle range, the user cannot see The electronic device 20 and the electronic device 100 in the area 12 have a completely transparent structure in the eyes of the user. It should be noted that the range of the inclination angle is related to factors such as the refractive index of the transparent casing 10, the setting position of the light guide surface 104, and the radian of the light guide surface 104.

2 and 3, in this embodiment, the electronic device 100 further includes a transparent touch film 30, the transparent touch film 30 is disposed on the transparent housing 10, and the sensing touch surface and the first surface of the transparent touch film 30 The orientation of 102 is the same. Specifically, the transparent touch film 30 is located directly below the first surface 102. In another embodiment, when the transparent touch film 30 is disposed on the first surface 102, the surface of the transparent touch film 30 is provided with a transparent protective layer to protect the transparent touch film 30. When the user touches the first surface 102, the transparent touch film 30 senses the touch information, thereby controlling the electronic device 100 to send a control signal. In one embodiment, the transparent touch film 30 may be a capacitive touch film or a resistive touch film. In this embodiment, the transparent touch film 30 is made of a transparent conductive material, such as indium tin oxide film (ITO) formed by deposition. Since the transparent touch film 30 and the transparent casing 10 are made of transparent materials, the electronic The part of the device 100 corresponding to the transparent touch film 30 can exhibit a transparent effect.

When a user observes the electronic device 100 from a certain angle above the electronic device 100, the light emitted from the electronic device 100 enters the human eye, and the propagation path of the light avoids the light-shielding area 12, that is, there is no light in the light-shielding area 12. Light is emitted from the first surface 102 or the light guide surface 104, the light-shielding area 12 forms a blind area of vision, and the user cannot observe the electronic device 20 in the light-shielding area 12, and the transparent touch film 30 used for touch operation can transmit light Therefore, when viewed from a certain angle range above the electronic device 100, the electronic device 100 has a completely transparent effect in the eyes of the user.
