Based on this, the inventors of the present application have proposed the electronic device 10 of the embodiments of the present application to improve the above-described drawbacks. Embodiments of the present application are specifically described below with reference to the accompanying drawings.

As shown in fig. 1, the present embodiment provides an electronic device 10, and the electronic device 10 includes a housing 20, a display screen 30, a main board, a battery, a front camera 40, a light source device 50, and an optical assembly 60 (shown in fig. 5), etc. The main board, the battery, the light source device 50, the optical module 60, and the like are disposed in the housing 20, and the front camera 40, the light source device 50, and the optical module 60 are disposed on the side of the electronic device 10 where the display screen 30 is disposed. The light source device 50 and the optical assembly 60 are used for forming a floating image through the display screen 30. The electronic device 10 provided in this embodiment will be described by taking a mobile phone as an example.

Referring to fig. 2, the housing 20 includes a casing 21, a front casing 22 and a rear cover 23, the casing 21 includes a middle plate 211 and a frame 212, the frame 212 is enclosed on an edge of the middle plate 211 and connected with the middle plate 211, the frame 212 protrudes from the middle plate 211, and the frame 212 protrudes from the middle plate 211 on opposite sides of the middle plate 211. The front shell 22 and the rear cover 23 are respectively assembled on two opposite sides of the middle plate 211, and the front shell 22 and the rear cover 23 are assembled and fixed with the frame 212; the rear cover 23, the housing 21 and the front case 22 together form a housing cavity, in which various components such as a motherboard, a camera, an antenna, a processor, the light source device 50, the optical assembly 60 and the like can be disposed, and the rear cover 23 can be provided with a camera mounting hole for mounting a rear camera.

Referring to fig. 3 and fig. 4, the display 30 is assembled on the frame 212 and disposed opposite to the middle plate 211. The display 30 may be a touch-sensitive display 30 that facilitates user interaction with the electronic device 10. The display screen 30 may also be used only for displaying information. Compared with a conventional LCD (Liquid CRYSTAL DISPLAY) screen or an OLED (Organic Light-Emitting Diode) screen. A front camera 40 hole may also be provided on the display screen 30 for positioning the front camera 40. In the present embodiment, the display screen 30 is provided with the light-transmitting region 31, and the light-transmitting region 31 is used to transmit the image light emitted from the light source device 50, and the light-transmitting region 31 on the display screen 30 may include a plurality of pixels 311, for example. Each pixel 311 includes a plurality of sub-pixels 3111, and each sub-pixel 3111 includes a first region 3112 and a second region 3113, the first region 3112 being provided with self-luminous chips, and the second region 3113 being filled with liquid crystal molecules.

The self-luminous chip may be an OLED, an AMOLED (Active Matrix Organic LIGHT EMITTING Diode ), a micro LED (micro light emitting Diode), or a QLED (Quantum dot LIGHT EMITTING Diode), and the type of the specific self-luminous chip is not limited herein.

It will be appreciated that a plurality of arrays of pixels 311 are disposed on the light transmissive region 31 and controlled to collectively display information. In each of the pixels 311 constituting the light transmitting region 31, the liquid crystal molecules of the second region 3113 enable illumination light to be transmitted from the display screen 30. Thus, the light transmitting region 31 can transmit the image light transmitted by the light source device 50. The first region 3112 may be located at a center of the sub-pixel 3111 and at a center of the second region 3113, that is, the second region 3113 is disposed around the first region 3112, so that light emitted from the self-light emitting chip in the first region 3112 can be uniformly diffused to the second region 3113. In other embodiments, the first region 3112 may be located at an edge of the sub-pixel 3111 or other locations, but the specific location is not limited thereto. The light-transmitting area 31 can be disposed on the display screen 30 near the hole of the front camera 40, so that when the floating image is a screen such as popup notification information, the touch area such as keyboard input on the display screen 30 is not blocked. In other embodiments, the display area of the entire display screen 30 may be the light-transmitting area 31, and the position of the light-transmitting area 31 is not limited herein.

Referring to fig. 3 again, the light source device 50 is used for emitting image light. Specifically, the light source device 50 may be disposed between the middle plate 211 and the display screen 30. In other embodiments, the light source device 50 may also be disposed on a side of the middle plate 211 away from the display screen 30, and an opening corresponding to the light-transmitting area 31 may also be disposed on the middle plate 211, and the image light may pass through the opening and then pass through the screen to form the floating image P1.

The light source device 50 may employ an LCD (Liquid CRYSTAL DISPLAY) screen for displaying information, which may be a TFT (Thin Film Transistor ) screen or an IPS (In-PLANE SWITCHING, in-plane switching) screen or an SLCD (Splice Liquid CRYSTAL DISPLAY, split-panel dedicated Liquid crystal display) screen. In other embodiments, the light source device 50 may employ an OLED screen for displaying information, which may be an AMOLED (Active Matrix Organic LIGHT EMITTING Diode) screen or a Super AMOLED (Super Active Matrix Organic LIGHT EMITTING Diode) screen or a Super AMOLED Plus (Super Active Matrix Organic LIGHT EMITTING Diode Plus, magic screen) screen.

The optical assembly 60 is used for receiving the image light emitted from the light source device 50 and guiding the image light to the light-transmitting area 31 so that the image light can be transmitted through the display screen 30 to form a floating image. In an exemplary embodiment of the electronic device 10, the optical component 60 includes a floating reflective device 61, the floating reflective device 61 includes a first grating layer 611 and a second grating layer 612, the first grating layer 611 includes a plurality of first stripe gratings 6111 extending along a first direction (e.g., an X direction in fig. 5), and the second grating layer 612 includes a plurality of second stripe gratings 6121 extending along a second direction (e.g., a Y direction in fig. 5), where the first direction is perpendicular to the second direction.

It will be appreciated that when the image light is emitted onto the floating reflective device 61, the image light is reflected by the first stripe grating 6111 and then emitted onto the second stripe grating 6121 (as shown in fig. 6), and then projected into the space after being reflected by the second stripe grating 6121 to form a floating image P1, where P1 is located in the light emitting direction of the image light (as shown in fig. 7). Further, in order to enhance the reflection efficiency of the suspended reflection device 61, a reflection layer may be further provided on the first and second stripe gratings 6111 and 6121.

Referring to fig. 3 again, in order to reduce the thickness of the electronic device 10, in the present embodiment, the light emitting direction of the light source device 50 may be substantially parallel to the plane of the display screen 30. Due to the limitation of the space in the electronic device 10, the optical assembly 60 may further include a reflector 62, where the reflector 62 is disposed on the light path of the light emitted from the floating reflection device 61, and is used to reflect the light emitted from the floating reflection device 61, so that the image light is transmitted through the display screen 30 to form the floating image P1.

Specifically, in the present embodiment, the mirror 62 may be a planar mirror, and the mirror 62 may be rotatably disposed at one side of the suspended reflecting device 61. It should be noted that the size of the reflecting mirror 62 needs to be matched with the size of the suspended reflecting device 61, that is, the reflecting mirror 62 is guaranteed to reflect all the light rays emitted from the suspended reflecting device 61. Meanwhile, by rotating the set mirror 62, the angle between the floating image P1 with respect to the display screen 30 can also be adjusted, as shown in fig. 8. Illustratively, the mirror 62 may be controlled by a drive motor or other drive device, and the angle between the user's line of sight and the display screen 30 may be obtained by a sensor such as a pupil tracking device, and by adjusting the floating image P1 to be always perpendicular to the user's line of sight, a better use experience may be obtained. In other embodiments, mirror 62 may also be a curved mirror, and the position of floating image P1 relative to display screen 30 may also be adjusted by adjusting the curvature of mirror 62.

Further, the use experience may also be enhanced by changing the position of the floating image P1 relative to the display screen 30. Accordingly, the light source device 50 is movably disposed in the middle plate 211. For example, referring to fig. 9, the optical assembly 60 may be disposed on a moving portion 80, and the moving portion 80 may slide along a plane parallel to the display screen 30. With the movement of the optical assembly 60, the position of the floating image P1 relative to the display screen 30 may also be moved. The electronic device 10 may improve the interaction experience between the user and the electronic device 10 by displaying the floating image P1 that can move relative to the display screen 30, where the floating image P1 may display, for example, a game screen, and the user may have a stronger visual impact.

Specifically, referring to fig. 10, in this embodiment, a first rail 2111 may be further disposed on the middle plate 211, and an extending direction of the first rail 2111 may be parallel to a length direction of the display screen 30. The moving portion 80 may be slidably disposed on the first rail 2111 and driven by a sliding driving portion, which may be a driving device such as a stepping motor, but is not limited thereto. Correspondingly, the light-transmitting area 31 on the display screen 30 may also be in a strip shape, and the strip-shaped arrangement is located corresponding to the movement track of the moving portion 80, so that when the moving portion 80 moves to any position on the first guide rail 2111, the light rays emitted by the suspended reflecting device 61 can all pass through the display screen 30 and form a suspended image P1 that can move relative to the display screen 30.

Further, with continued reference to fig. 10, in other embodiments, a second guide rail 2112 may be provided, and the extending direction of the second guide rail 2112 may be perpendicular to the extending direction of the first guide rail 2111. For example, second rail 2112 may be provided directly on middle plate 211 and parallel to the shorter side of display 30. The first guide rail 2111 is slidably provided on the second guide rail 2112, and the entire first guide rail 2111 can be slid in the extending direction of the second guide rail 2112. Correspondingly, in the present embodiment, the optical assembly 60 and the light source device 50 are disposed on the moving portion 80 together, and move together with the moving portion 80, and meanwhile, the display area on the entire display screen 30 can be the transparent area 31, so that when the moving portion 80 is at any position, the floating image P1 can be formed through the display screen 30, and the floating image P1 can move within a certain range, so as to bring better interaction and experience effects.

Referring to fig. 3 again, in order to improve the display effect and the use experience, the optical assembly 60 may further include a zoom assembly 63, where the zoom assembly 63 is disposed between the display screen 30 and the middle plate 211, and the zoom assembly 63 is used for changing the interval between the floating image P1 formed by the image light and the display screen 30, so that a user can observe images with different distances in the use process, and improve the use experience. For example, the floating image P1 may be a message popup screen, and when displayed, the position of the floating image P1 may be from near to far relative to the display screen 30, so that the message popup screen may be more dynamic and has a shock feeling.

In the present embodiment, the zoom assembly 63 is disposed on the optical path before the image light enters the suspended reflecting device 61. After the image light is zoomed, a plurality of light beams included in the image light may enter the floating reflection device 61 at different angles, and after passing through the floating reflection device 61, the plurality of light beams are focused to form a floating image P1 spaced apart from the display screen 30. In other embodiments, the zoom assembly 63 may also be disposed on the optical path behind the suspended reflecting device 61, where the design position of the zoom assembly 63 is different according to the specific internal structure of the electronic device 10, and the specific disposition position is not limited herein.

In this embodiment, referring to fig. 11, the zoom assembly 63 includes a lens group 631 and a driving assembly 632, the lens group 631 is disposed between the floating reflection device 61 and the light source device 50 and is located on the optical path of the image light, and the driving assembly 632 is in driving connection with the lens group 631 and is used for driving the lens group 631 to change the focal length so as to change the distance between the floating image formed by the image light and the display screen 30.

Illustratively, the lens group 631 includes a first convex lens 6311, a concave lens 6312, and a second convex lens 6313 that may be coaxially disposed, the second convex lens 6313 being disposed near the display device, the concave lens 6312 being disposed between the first convex lens 6311 and the second convex lens 6313. By moving the concave lens 6312 away from or closer to the first convex lens 6311 simultaneously with the second convex lens 6313, the focal length of the lens group 631 can be changed for the purpose of adjusting the spacing between the floating image and the display screen 30.

Specifically, the drive assembly 632 may include a voice coil motor having a linearly movable drive end 6321. The driving end 6321 may be configured in a ring shape and may move linearly along a central axis extending direction of the ring-shaped driving end 6321. In this embodiment, the annular driving end 6321 may be sleeved on the concave lens 6312, and the concave lens 6312 is in transmission connection with the second convex lens 6313. During the controlled linear movement of the driving end 6321, the concave lens 6312 and the second convex lens 6313 move so that the concave lens 6312 and the second convex lens 6313 move away from or close to the first convex lens 6311.

It will be appreciated that as shown in fig. 12, as the concave lens 6312 and the second convex lens 6313 are away from the first convex lens 6311, the focal length of the lens group 631 increases, and the distance separating the floating image from the display screen 30 also increases; in contrast, when the concave lens 6312 and the second convex lens 6313 are close to the first convex lens 6311, the separation distance between the suspended image and the display screen 30 is also reduced. In other embodiments, the focal length of the lens group 631 may be changed by driving the first convex lens 6311, and of course, the zoom function of the lens group 631 may be achieved by providing more lenses, and the arrangement and the sequence of the plurality of lenses in the lens group 631 are merely examples in this embodiment, and in other embodiments, the arrangement and the sequence of the lenses are not limited.

In other embodiments, the zoom assembly 63 may also be a liquid lens that may change curvature. In particular, at least a portion of the liquid lens may be deformed to change the curvature of the liquid lens. The liquid lens can be arranged in a round table or a conical cavity. Because the cavity is round platform or circular cone, the liquid lens in the cavity is extruded by the inner side wall of the cavity in the moving process, so that at least part of the liquid lens is deformed, the curvature of the liquid lens can be changed through the deformation of at least part of the liquid lens, so that the curvature of the liquid lens can be accurately controlled, and all levels of zooming can be realized by the liquid lens. The driving mode of the liquid lens can be a mode of changing the pressure difference between two sides of the lens in the cavity, and the specific driving mode is not limited herein. In other embodiments, the liquid lens may also include two cavities separated by a partition made of flexible material, and the cavity is filled with liquid, so that the curvature of the partition can be changed by changing the volume of the liquid, and the purpose of changing the focal length can be achieved.

In the electronic device 10 provided by the embodiment of the application, after the image light generated by the light source device 50 passes through the floating reflection device 61, the image light can penetrate through the display screen 30 and form the floating image with a certain interval with the display screen 30, so that the picture displayed by the electronic device 10 has higher ornamental value and the use experience can be improved.

The electronic device 10 of the present application may be a mobile phone or a smart phone (e.g., an iPhone-based (TM), android-based (TM) phone), a Portable game device (e.g., nintendo DS (TM), playStation Portable (TM), gameboy ADVANCE TM, iPhone (TM)), a laptop, a PDA, a Portable internet device, a music player, and a data storage device, other handheld devices, and devices such as watches, headphones, pendants, headphones, etc., and the electronic device 10 may also be other wearable devices (e.g., a head-mounted device (HMD) such as an electronic glasses, electronic clothing, electronic bracelets, electronic necklaces, electronic tattoos, electronic device 10, or smart watches).
