Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 2, an embodiment of the present invention provides an electronic device, including:
the device module 1, the device module 1 has optical devices 11;
the display module 2, the display module 2 has light guiding structure 21, the display module 2 and the device module 1 can be slipped relatively;
the device module 1 does not slide out relative to the display module 2, the device module 1 is located at a first position, the device module 1 slides out relative to the display module 2, and the device module 1 is located at a second position;
when the device module 1 is at the first position, the display module 2 shields the optical device 11, and the optical device 11 can conduct light with the outside through the light guide structure 21;
when the device module 1 is at the second position, the display module 2 does not shield the optical device 11, and the optical device 11 can conduct light with the outside.
The display module 2 and the device module 1 can slide relatively, the display module 2 can slide relatively along the device module 1, and the device module 1 can also slide relatively along the display module 2. In order to realize the relative sliding between the display module 2 and the device module 1, a sliding structure may be disposed between the display module 2 and the device module 1, and the sliding structure may be an existing sliding structure, which is not described in detail in the embodiments of the present invention.
Fig. 1 shows a schematic diagram of the device module 1 in a first position, that is, when the device module 1 does not slide out relative to the display module 2, at this time, the display module 2 covers the device module 1, the display module 2 blocks the optical device 11, and light of an external environment can be transmitted to the optical device 11 through the light guide structure 21 (an arrow in fig. 1 is a light transmission schematic diagram), or light of the optical device 11 can be transmitted to the external environment through the light guide structure 21.
Fig. 2 shows the device module 1 in the second position, that is, the device module 1 slides out relative to the display module 2, at this time, the area where the optical device 11 of the device module 1 is located is exposed, the display module 2 does not shield the optical device 11, and the optical device 11 can conduct light with the external environment (an arrow in fig. 2 is a light conduction diagram).
It can be understood that when the device module 1 is at the first position, the electronic device is in a closed state, and the device module 1 is covered by the display module 2; when the device module 1 is in the second position, the electronic apparatus is in a slide-open state.
When the device module 1 is at the first position, in order to realize the light guiding function of the light guiding structure 21, the light guiding structure 21 may be at least partially opposite to the optical device 11, or in a case where the light guiding structure 21 is not opposite to the optical device 11, by providing an optical structure, such as a polarization structure, a reflection structure, a light guiding column, etc., on the device module, light may be transmitted to the optical structure through the light guiding structure 21, and then transmitted to the optical device 11 through the optical structure.
Generally, in order to ensure the normal operation performance of the optical device 11, the width and thickness of the optical device 11 usually need to reach a certain size, and the thickness of the optical device 11 is usually larger than the normal thickness of the display module 2. While the main function of the light guiding structure 21 is light conduction, the light guiding structure 21 is not greatly limited in width and thickness. It can be seen that, compared with the case that the optical device 11 is disposed on the display module 2, the light guide structure 21 disposed on the display module 2 has a reduced occupied width space and thickness space. Therefore, by disposing the optical device 11 on the device module 1 and disposing the light guide structure 21 on the display module 2, the thickness of the display module 2 is not increased, the overall appearance of the electronic device can be improved, the overall thickness of the electronic device can be reduced, and the electronic device can be conveniently held. Because the space occupied by the light guide structure 21 is smaller in the display module 2, the embodiment of the invention can improve the screen occupation ratio of the display module 2.
In addition, in the embodiment of the present invention, the light guide structure 21 is disposed on the display module 2, so that the optical device 11 on the device module 1 can work normally no matter the device module 1 is located at the first position or the second position, and the working performance of the electronic apparatus is improved.
In the embodiment of the present invention, the relative sliding between the display module 2 and the device module 1 can be realized by manual operation of a user, or can be realized by setting a driving device in the electronic device and controlling the driving device. The embodiment of the present invention is not limited thereto.
In the embodiment of the present invention, the optical device 11 may be at least one of an ambient light sensor, a proximity sensor, a flash, a camera, a fingerprint recognition device, and the like.
The ambient light sensor detects ambient light parameters and adjusts the brightness of the display screen according to the detection condition. It can be seen that the ambient light sensor should be kept working constantly to enable the electronic device to continuously control the brightness of the display screen.
For the above reasons, the optical device 11 is an ambient light sensor, and the light guide structure 21 is used to guide ambient light to the ambient light sensor. Like this, no matter 2 roll-offs of the relative display module assembly of device module 1 or not roll-off, ambient light sensor homoenergetic on the device module 1 can detect ambient light, has improved electronic equipment's working property.
Generally, as shown in fig. 3 to 4, the device module 1 may be provided with other optical or non-optical functional devices, such as a camera, a flash, a proximity sensor, a fingerprint recognition device, and the like, in addition to the optical device 11. The frequency of use of these functional devices is often lower than the frequency of use of the display module 2, so that the electronic device is generally in a closed state, and when some functional devices need to be used, the device module 1 is slid away to expose the corresponding functional devices.
Other alternative implementations of the electronic device according to the embodiment of the present invention will be described in detail below with reference to fig. 5 and 6.
Optionally, the display module 2 includes a frame 22 and a display screen 23, and the light guide structure 21 is disposed in the frame 22 or a space between the frame 22 and the display screen 23. When the light guide structure 21 is disposed in the frame 22, the frame 22 is provided with a receiving groove for receiving the light guide structure 21, or the frame 22 is provided with a light guide through hole for the light guide structure 21 to pass through.
In this embodiment, the light guide structure 21 may be disposed in the edge area of the frame 22 as much as possible to further improve the screen ratio of the display module 2.
Further, the display module 2 further includes a first cover plate 24, and the first cover plate 24 covers the display screen 23 and is overlapped on the frame 22;
the light guide structure 21 is disposed in an area of the frame 22 below the first cover plate 24;
the light guide structure 21 may be light-conductive with the outside through the first cover plate 24.
The first cover plate 24 should be made of a material with good light transmission performance, such as glass.
Through setting up first apron 24, not only can improve display module assembly 2's wholeness, can improve display module assembly 2's outward appearance performance. The light guiding structure 21 can be protected, and the display screen 23 can be protected.
Optionally, the light guide structure 21 is a light guide embedded in the frame 22; or,
the light guide structure 21 is a light guide through hole formed in the frame 22.
When the light guide structure 21 is a light guide member, the light guide member is made of a light-transmitting material with a good light guide effect, such as glass, Polymethyl methacrylate (PMMA), Polycarbonate (PC), and the like. The light guide may be bonded to the frame 22 or injection molded to the frame 22. When the light guide structure 21 is a light guide through hole, an optical layer, such as a reflective layer, may be disposed on an inner wall of the light guide through hole to improve the light guide performance of the light guide through hole.
Optionally, the surface of the first cover plate 24 contacting the frame 22 is provided with a diffusion layer 241.
The diffusion layer 241 may be a diffusion ink layer or a diffusion film layer, and external ambient light may be better diffused to the light guide structure 21 through the diffusion layer 241. In addition, the surface of the first cover plate 24 contacting with the frame 22 may be further provided with a silk-screen appearance ink layer to improve the appearance performance of the display module 2.
Optionally, the device module 1 includes a second cover plate 12, the optical device 11 is disposed below the second cover plate 12, and the optical device 11 may conduct light with the outside through the second cover plate 12.
Through the above setting, the second apron 12 can protect the optical device 11 to the setting of second apron 12 can improve the wholeness of device module 1, can improve the outward appearance performance of device module 1.
The second cover plate 12 should be made of a material with good light transmission properties, such as glass.
In order to improve the appearance performance of the device module 1, the surface of the second cover plate 12 facing the optical device 11 may also be provided with a silk-screen appearance ink layer. In this case, in order to transmit the light of the external environment to the optical device 11 through the second cover plate 12, the light-transmitting window 13 should be opened on the silk-screen appearance ink layer of the second cover plate 12 at the position facing the optical device 11.
In addition to the above structure, the device module 1 further includes other devices, for example, a circuit board 14 electrically connected to the optical device 11, and the other devices are not specifically described in the embodiment of the present invention.
Optionally, when the device module 1 is in the first position, the optical device 11 is disposed opposite to the light guide structure 21. Thus, most of the light emitted from the light guide structure 21 can be transmitted to the optical device 11, thereby improving the light guiding performance of the light guide structure 21.
Optionally, one end of the light guide structure 21 close to the device module 1 is larger than one end of the light guide structure 21 far from the device module 1.
On the one hand, in order to maximize the screen ratio of the display module 2, the light guide structure 21 should occupy as little space as possible that the display screen 23 can occupy. In view of this, the size of the end of the light guiding structure 21 away from the device module 1 (i.e. the end close to the first cover plate 24) is made as small as possible, so that more space is available for the display 23. On the other hand, in order to improve the light guiding performance of the light guiding structure 21, the area of the light guiding structure 21 facing the optical device 11 should be as large as possible. In view of this, the size of the light guide structure 21 near the end of the device module 1 is made as large as possible, so that a larger light transmission area can be provided.
Further, the light guide structure 21 is disposed on the display module 2 in an inverted T shape. If the inverted T-shaped light guide structure 21 is divided into a vertical portion perpendicular to the first cover plate 24 and a horizontal portion parallel to the first cover plate 24, the vertical portion of the light guide structure 21 extends at least the height of the display screen 23 from the first cover plate 24 to a direction close to the device module 1, and the horizontal portion of the light guide structure 21 is staggered from the area of the frame 22 where the display screen 23 is disposed below the display screen 23.
The light guide structure 21 may be in a trapezoid shape, a triangle shape or other irregular shapes besides the inverted T-shape.
In the embodiment of the present invention, taking the optical device 11 as an example of an ambient light sensor, when the electronic device is in a closed state, a path of light received by the optical device 11 is: external ambient light → first cover plate → light guiding structure → second cover plate → ambient light sensor. When the electronic device is in the sliding-open state, the path of the optical device 11 receiving the light is: external ambient light → second cover plate → ambient light sensor.
Because the receiving light path of the ambient light sensor is inconsistent between the closed state and the sliding state of the electronic device, in order to ensure the accuracy of ambient light detection, the electronic device is in different states, and different calibration parameters need to be set, and the calibration parameters may include gain parameters and cover plate fitting parameters.

In the first position, the electronic device is in a closed state, and in the second position, the electronic device is in a sliding state. Assume that in the closed state, the calibration parameters are set a, and in the slide-open state, the calibration parameters are set B.
