The two transmission surfaces 122 may be respectively located at the left and right sides of the optical unit 120. The transmissive surface 122 is for transmitting display light. The number of the reflecting surfaces 121 may be four. The four reflecting surfaces 121 are annularly arranged. Each reflective surface 121 is perpendicular to main display 11. The reflective surface 121 may be used to reflect display light.

It is understood that the reflective surface 121 may be a reflective coating applied on the optical unit 120, or may be an optical element having reflective optical energy, such as a mirror. In addition, in order to increase the reflection efficiency of the reflection surface 121, a high reflection layer may be coated on the reflection surface 121. Similarly, the transmission surface 122 may be further provided with an antireflection film layer (not shown) to increase the transmittance of the display light.

The display device 13 may be provided on one side of the optical structure 12. The display device 13 may be disposed in the middle, bottom, top, or the like of the electronic apparatus 10. The setting position of the display device 13 on the electronic device 10 is not limited, and the setting position of the display device 13 may be set according to the use requirement. Also, the number of the display devices 13 may be one or more. The number of the display devices 13 is not limited here.

The display device 13 may include a light shielding member 131 and a sub-display 132. The light shielding member 131 defines a display cavity 133. The sub-display 132 is disposed within the display cavity 133.

Referring to fig. 3 and 4, an opening 134 is formed on a side of the light shielding member 131 close to the optical structure 12. The side of the light-shielding member 131 provided with the opening 134 faces the optical structure 12. Also, the light blocking member 131 may be connected to the optical structure 12. The display device 13 is fixedly connected to the optical structure 12 through the light shielding member 131.

The light shielding member 131 may be a square box structure. An opening 134 is provided on one side of the cube-shaped structure. It is understood that the shape of the light shielding member 131 is not limited to a square box, and the light shielding member 131 may also be a circular housing or an irregular housing. The shape of the light shielding member 131 may be adapted to the shape of the sub-display 132.

The inner sidewall of the light-shielding member 131 is provided with a light-absorbing layer (not shown). The light absorbing layer may absorb the interference light entering the display cavity 133, ensuring accurate display of the display light. It is to be understood that the light absorbing layer may be a black ink layer or the like.

The sub-display 132 is used to display an image and emit display light. The secondary display screen 132 can be an LED display screen or a liquid crystal display screen; moreover, the sub-display 132 may be a flat display, and may also support a 3D stereoscopic display, and the type of the sub-display 132 is not limited herein.

Referring to fig. 2, the front side of the sub-display 132 for displaying images is disposed toward the opening 134. Display light of the sub-display 132 is incident on the optical structure 12 through the opening 134 of the light blocking member 131. The optical structure 12 reflects and converges the display light to the side of the main display 11 opposite to the optical structure 12, and forms a floating real image 20. The floating real image 20 may be a 2D planar real image or a 3D stereoscopic real image.

The secondary display 132 is disposed obliquely with respect to the optical structure 12. The display light emitted from the sub-display 132 is incident on the reflection surface 121 of the optical structure 12 from one side of the optical structure 12 at a certain incident angle. The reflective surface 121 will reflect the display light to the other side of the optical structure 12 at a certain reflection angle to form the floating real image 20. The display on the secondary display 132 is symmetrical to the floating real image 20 about the plane of the optical structure 12. In particular, in this embodiment, the secondary display 132 is disposed obliquely with respect to the optical structure 12. The secondary display 132 is disposed on one side of the optical structure 12 at an angle relative to the optical structure 12, and the floating real image 20 is also disposed on the other side of the optical structure 12 at an angle relative to the optical structure 12. Since the optical structure 12 is parallel to the main display 11, the floating real image 20 is also disposed at an angle corresponding to the main display 11.

Referring to fig. 2, the floating real image 20 is imaged on the front side of the main display 11 and is also disposed obliquely with respect to the main display 11. Since the line of sight of the human eye is also generally inclined with respect to main display 11, suspended real image 20 arranged obliquely with respect to main display 11 may be completely within the visual angle range of the human eye. The suspended real image 20 can be conveniently watched by human eyes, and the complete suspended real image 20 can be observed by the human eyes. Moreover, the viewing angle of the human eye can be approximately perpendicular to the floating real image 20, so that the floating real image 20 viewed by the human eye has a planar effect with the display object. Therefore, the human eye can observe the floating real image 20 without causing the problem that the floating real image 20 is deformed due to the difference of the viewing angles.

The front side of the sub-display 132 for displaying images is disposed toward the opening 134. One side of the sub-display 132 near the opening 134 is flush with the side edge of the light shielding member 131 at the opening 134. One side of the sub-display 132 close to the opening 134 is located at the opening end of the light shielding member 131, so that the sub-display 132 occupies as little space as possible of the light shielding member 131.

Referring to fig. 4, a side of the sub-display 132 away from the opening 134 is flush with a side edge of the light shielding member 131 away from the optical structure 12. Referring to fig. 5, the side of the sub-display 132 away from the opening 134 is located at the other end of the light shielding member 131, so the projection length of the sub-display 132 in the light shielding member 131 is the length of the light shielding member 131, the sub-display 132 does not occupy the space of the light shielding member 131, and the size of the light shielding member 131 just accommodates the sub-display 132. Therefore, the placement position of the auxiliary display 132 can make the display device 13 light and thin, and meet the trend of light and thin portable electronic device 10.

Referring to fig. 6, the sub display 132 is provided with a wire (not shown), and the sub display 132 can transmit power and display signals through the wire. One side of the light shielding member 131 is opened with a wire passing hole 135 for passing a wire of the sub display 132. One side of the sub-display 132 for displaying images is the front side of the sub-display 132, and the other side is the back side of the sub-display 132. And the wire through hole 135 is positioned at one side of the rear surface of the sub display 132. The wire through hole 135 is formed in the back surface of the secondary display screen 132, so that interference light rays inside the electronic device 10 are prevented from entering the display cavity 133 from the wire through hole 135, interference is generated on display light rays emitted from the front surface of the secondary display screen 132, and the display effect of the secondary display screen 132 is reduced.

The electronic device 10 further comprises a middle frame (not shown). The outer side of the light shielding member 131 is provided with a connecting lug 136. The engaging lug 136 is connected to the middle frame. It can be understood that the connection lug 136 and the middle frame can be fixedly connected by means of bolts or welding, so as to realize the fixed arrangement of the display device 13. Since the optical structure 12 is fixedly connected to the display device 13, the display device 13 is fixedly mounted, so that the optical structure 12 is fixedly mounted. Therefore, the display device 13 can be fixed by connecting the engaging lug 136 to the middle frame, so as to prevent the optical structure 12 from being directly connected to the main display 11, and prevent the main display 11 from being affected by the pressure at the joint of the main display 11.

The engaging lug 136 is plural. The connecting lugs 136 are oppositely arranged at two opposite sides of the light shielding member 131. The plurality of engaging lugs 136 can enhance the stability of the display device 13, and ensure that the display device 13 and the optical structure 12 can be stably disposed. Specifically, in the present embodiment, there are two engaging lugs 136. The two connecting lugs 136 are respectively and oppositely arranged at the two opposite sides of the light shielding piece 131, so that the mutual balance of the fixing acting force from the connecting lugs 136 on the light shielding piece 131 can be ensured, and the light shielding piece 131 can not shake or shift.

Referring to fig. 3 again, in particular, the connecting lug 136 is provided with a fixing hole 137. The engaging lug 136 is fixedly connected with the middle frame through the fixing hole 137. It is understood that the fixing holes 137 may be screw holes through which the coupling lugs 136 may be directly coupled to the middle frame by screws.

Therefore, the electronic device 10 described above has at least the following advantages over the conventional electronic device 10:

first, in the electronic device 10, the sub-display 132 may emit display light, and the display light may be projected and reflected to the outside of the electronic device 10 through the optical structure 12. Then, the display light of the sub-display 132 may form the floating real image 20 on one side of the main display 11, so as to achieve the effect of floating display on the main display 11. Therefore, the display area of the electronic device 10 is larger than the display area of the main display 11, the display interface of the electronic device 10 is increased, and the user experience is improved.

Moreover, the sub-display 132 is disposed in the light shielding member 131, and the light shielding member 131 can block external light from interfering with the display of the sub-display 132, thereby improving the display effect of the sub-display 132. Moreover, the display device 13 may be a modular structure, and the auxiliary display screen 132 is installed by fixing the light shielding member 131, so that the operation is convenient and the implementation is convenient.
