Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the present disclosure provides a sensor integrated module, fig. 1 is a schematic structural diagram of a sensor integrated module according to an exemplary embodiment, as shown in fig. 1, the sensor integrated module 100 includes:
a carrier plate 101;
the light emitting module 102 is positioned on the bearing plate 101 and can emit light rays with a first wavelength;
at least two types of light receiving modules 103 are located on the carrier plate 101, and include:
a first-type light receiving module 1031 for receiving light of a first wavelength;
a second light receiving module 1032 for receiving light with a second wavelength; wherein the second wavelength is different from the first wavelength;
and the isolation assembly 104 is located on the bearing plate 101 and used for isolating the at least two types of light receiving modules 103 from the light emitting module 102.
In the embodiment of the present disclosure, the sensor integrated module is an integrated module of a light processing sensor. A plurality of types of optical devices are integrated in the sensor integrated module, and the sensor integrated module has multiple functions. Here, sensors that receive or emit different light signals are considered to be different types of optics, e.g., optics that receive infrared light and optics that receive ultraviolet light are considered to be different types of optics.
The bearing plate is used for bearing the light emitting module and the at least two types of light receiving modules, not only plays a bearing role in structure, but also provides electrical support for the light emitting module and the at least two types of light receiving modules.
Thus, in some embodiments, the carrier plate may also be a Circuit Board, e.g. a Printed Circuit Board (PCB). Due to the integration of multiple devices, in the embodiment of the disclosure, the light emitting module and the at least two types of light receiving modules are arranged on the same carrier plate.
In the embodiment of the present disclosure, the light emitting module refers to an optical device capable of emitting light with a first wavelength, for example, a distance collector emitting infrared light, an ultraviolet irradiation lamp emitting ultraviolet light, or a device emitting visible light. The first wavelength includes: a wavelength corresponding to infrared light, a wavelength corresponding to ultraviolet light, or a wavelength corresponding to visible light.
The light receiving module has at least two types, that is, includes at least two optical devices capable of receiving different wavelengths, for example, the light receiving module may be an infrared receiving module, an ultraviolet receiving module, or a visible light receiving module.
In the embodiment of the disclosure, the at least two types of light receiving modules include a first type of light receiving module and a second type of light receiving module, and the first type of light receiving module and the second type of light receiving module receive light rays of different wavebands. As described above, infrared rays, ultraviolet rays, and visible light belong to different wavelength bands.
Here, when the light emitting module capable of emitting light of the first wavelength is an infrared ray emitter, the first light receiving module of the at least two types of light receiving modules is a device for collecting infrared rays. Correspondingly, the second type of light receiving module is a light receiving device for receiving light with other wavelengths than infrared light, for example, the second light receiving module may be a device for collecting visible light, or a device for collecting ultraviolet light.
Since the light emitting module and the first type of light receiving module are both associated with light of the first wavelength, in some embodiments, the light emitting module and the first type of light receiving module may be two modules in a distance sensor for emitting infrared rays for ranging. Since the second type of light receiving module is used for receiving light with the second wavelength, in some embodiments, the second type of light receiving module may be a module included in a light sensor and used for collecting visible light, or an ultraviolet sensor and used for detecting whether the environment includes ultraviolet rays with a higher concentration.
The isolation component is a device which isolates the light receiving module and the light emitting module so that the emission and the reception of light rays are not interfered with each other. The isolation component can realize that the emission and the reception are not interfered with each other by arranging a baffle made of isolation materials between at least two types of light receiving modules and light emitting modules; the light receiving module and the light emitting module can be separated in layout, namely, the light receiving module and the light emitting module are arranged on the bearing plate at intervals of preset length, so that the light emitting and the light receiving are not interfered with each other.
In order to provide better isolation and to provide practical isolation efficiency, in some embodiments, the height of the isolation assembly is greater than the height of the optical transmission module, i.e., since the bottom of the optical transmission module and the bottom of the isolation assembly are both located on the carrier plate, the distance between the top of the isolation assembly and the carrier plate needs to be greater than the distance between the top of the optical transmission module and the carrier plate. As one example, the height of the isolation component may be M times the height of the optical transmit module; m can be a positive integer greater than 1, e.g., M is equal to 2 or 3, etc. Therefore, through the arrangement of the height, the light emitted by the light emitting module can be ensured not to directly enter the light receiving area corresponding to the light receiving module due to no blockage as much as possible, so that the isolation effect is achieved.
In other embodiments, the isolation element may be made of a material having light absorption or reflection properties for absorbing or reflecting light, thereby preventing the transmitted light from interfering with the light received by the partition wall. The light absorption material may be black material or opaque reflective material.
Here, place two kinds of light receiving module in the same side of optical transmission module, keep apart with optical transmission module through isolation subassembly, can reduce the interference of light transmission to light reception, for example, when optical transmission module transmits infrared light, and first kind light receiving module receives infrared light, if both positions are more closely can lead to not having infrared light in the air, nevertheless because optical transmission module has transmitted infrared light for this infrared light can be sensed to first kind light receiving module, has just produced erroneous judgement this moment.
Therefore, the light emitting module and the at least two types of light receiving modules are integrated together to form a sensor integrated module, so that the receiving and the transmitting of light signals with different wavelengths can be realized only by one device, and the cost of the device is reduced. Moreover, because the receiving and the transmitting are integrated, on the basis of meeting various application requirements, and because of the integration of devices, the occupied space can be reduced and the layout is more favorable compared with the case that a plurality of sensors with single functions are separately arranged in volume.
In some embodiments, each type of light receiving module includes: the device comprises a photosensitive device and an optical filter covering the photosensitive surface of the photosensitive device.
That is, the first-type light receiving module and the second-type light receiving module in the above embodiments each include: a light sensing device and a light filter.
Here, the light sensing device is used to sense light and convert a light signal into an electrical signal. The photosensitive device includes: a Charge Coupled (CCD) device or a Complementary Metal Oxide Semiconductor (CMOS) device. The photosensitive device can realize the collection of optical signals with specific wavelengths. In the embodiment of the present disclosure, a surface of the photosensitive device for collecting the optical signal is referred to as a photosensitive surface.
The filter is used to allow light of a specific wavelength to pass through, while filtering out light of other wavelengths.
In some embodiments, the filter comprises: the first filter is used for allowing the light with the first wavelength to pass through, and the second filter is used for allowing the light with the second wavelength to pass through; the first optical filter is a component of the first type of light receiving module, and the second optical filter is a component of the second type of light receiving module. For example, the first type of light receiving module includes: the distance sensor comprises a distance sensor and a first optical filter attached to the distance sensor. For another example, the second type of light receiving module includes: the light sensor and a second optical filter attached to the light sensor.
The distance sensor may detect a distance between the target object and the mobile terminal by emitting infrared light, and the light sensor may be used to detect brightness of the light.
The light receiving module can collect light rays with corresponding wavelengths conveniently by covering the light filter on the light sensing surface of the light sensing device. For example, when first wavelength is the wavelength that infrared light corresponds, can filter other wave bands through the light filter, only allow infrared light to see through, at this moment, infrared light just can directly be sensed to first kind light receiving module, also is favorable to the promotion of induction speed.
In some embodiments, fig. 2 is a schematic structural diagram of a sensor integrated module according to an exemplary embodiment, and as shown in fig. 2, a distance between a first type of light receiving module and a light emitting module is smaller than a distance between a second type of light receiving module and the light emitting module.
Through keeping away from optical transmission module with second type light receiving module and placing, can reduce because the impact diffusion of the air current that optical transmission module produced to the light of second wavelength, and the problem that leads to and be unfavorable for the receipt of second type light receiving module takes place, inaccuracy when reducing second type light receiving module and regard as light sensor to the detection of ambient light takes place, and can avoid the interference of the light of first wavelength to the light of second wavelength as far as possible, make the collection of second type light receiving module to the light of second wavelength more rapid.
Here, the sensor integrated module is applied to a smart phone as an example to describe the positional relationship between the light emitting module, the first light receiving module and the second light receiving module: fig. 2 shows a schematic diagram of a position relationship between a light emitting module, a first type light receiving module, and a second type light receiving module in a smartphone, as shown in fig. 2, a thickness of a transparent cover plate of the smartphone is h, a distance between the light emitting module and an isolation component is D1, a distance between the isolation component and the first type light receiving module is D4, a distance between the first type light receiving module and an intersection point of a light incident path of the first type light receiving module and an outer surface of the transparent cover plate is D3, and a distance between an intersection point of a light incident path of the second type light receiving module and the outer surface of the transparent cover plate and the second type light receiving module is D2. The distance between the light emitting module and the transparent cover plate in the sensor integrated module is H1, the distance between the first type of light receiving module and the transparent cover plate is H2, and the distance between the second type of light receiving module and the transparent cover plate is H3. The included angle between the light emitting path of the light emitting module and the normal line is theta1The included angle between the incident light path of the first type light receiving module and the normal is theta3The included angle between the incident light path of the second type light receiving module and the normal is theta2。
Then, the distance D between the light emitting module and the second type of light receiving module:
distance D' between the second type light receiving module and the first type light receiving module:
D'>D2+D3＝[(H3+h+0.5)tanθ2+(H2+h+0.5)tanθ3+1]
here, 0.5 is a distance error, and 1 is a total error of the three placement on the carrier plate when the light emitting module, the first type light receiving module and the second type light receiving module are located on the same straight line.
In other embodiments, the top of the isolation component is in contact with the transparent cover plate, so that the receiving interference of the second type light receiving module caused by the conduction interference of the light emitted by the light emitting module to the second type light receiving module can be reduced as much as possible.
In some embodiments, the transparent cover may be a transparent glass cover or a transparent plastic cover. The material of this transparent cover plate includes: glass or plastic, etc. Here, the transparent cover plate can be favorable to the display of information, also can play the guard action to the screen, prevents that mobile terminal from directly damaging the screen after dropping.
In some embodiments, the sensor integration module further comprises:
a transparent module housing; the module comprises a bearing plate, a light emitting module, at least two types of light receiving modules and a module shell, wherein the bearing plate, the light emitting module and the at least two types of light receiving modules are all positioned in the module shell;
and the protective sleeve surrounds the module shell, is provided with an opening, and is aligned with the occupied area of the light emitting module and the at least two types of light receiving modules on the bearing plate.
Here, the module case is used to wrap the carrier plate, the light emitting module, the first type light receiving module and the second type light receiving module, and the module case may be made of a plastic material or a light metal material in consideration of the portability and cost of the device.
The module shell is transparent, various light rays can conveniently penetrate through the transparent module shell, and the light rays with certain wavelengths cannot penetrate through the transparent module shell.
The protective sleeve is used for protecting the sensor integrated module and can be made of silica gel or leather.
In order to facilitate the light to pass through, an opening may be provided in the protective cover, which opening is aligned with the area occupied by the light emitting module and the at least two types of light receiving modules on the carrier plate. Therefore, external light can pass through the opening and then reach the photosensitive surfaces of the at least two types of light receiving modules through the transparent module shell, and therefore collection is achieved. Similarly, the light emitted from the light emitting module can reach the opening through the transparent module housing and then be emitted to the outside through the opening. Thus, the design of the opening facilitates the transmission of light, and the speed of emitting and collecting light is faster.
In some embodiments, the area of the opening is larger than the area of the light emitting module and the area of the at least two types of light receiving modules occupied on the carrier board.
Here, because optical transmission module and two at least types of light receiving module all set up on same loading board, so for the convenience of the transmission and the receipt of light, make the protective sheath not hinder with the formation of receiving of light, the open-ended area on the protective sheath needs to be greater than optical transmission module and two at least types of light receiving module shared region on the loading board, just can guarantee going on smoothly of the transmission and the receipt of light with this, can not appear because the area problem, make the effect of transmission and receipt differ, thereby influence some functions of sensor collection moulding group.
So, the sensor integrated module that this disclosed embodiment provided, through with the integrated reduce cost that is in the same place of multiclass sensor, it is also comparatively convenient in the overall arrangement. The sensor integration module comprises a light emitting module capable of emitting light with a first wavelength, at least two types of light receiving modules and an isolation assembly, wherein the at least two types of light receiving modules are isolated from the light emitting module through the isolation assembly, and interference between emitted light and received light is prevented. Moreover, because the receiving and the transmitting are integrated, on the basis of meeting various application requirements, and because of the integration of devices, the occupied space can be reduced and the layout is more favorable compared with the case that a plurality of sensors with single functions are separately arranged in volume. In addition, set up the protective sheath that contains the opening, can be convenient for all kinds of light to see through, and can not have the hindrance to seeing through of light, also comparatively convenient in the application.
An embodiment of the present disclosure further provides a mobile terminal, fig. 3 is a schematic structural diagram of a mobile terminal shown according to an exemplary embodiment, and as shown in fig. 3, the mobile terminal 300 includes:
a screen 301;
the sensor integration module 302 of the above embodiment;
and the middle frame 303 is positioned between the screen 301 and the sensor integration module 302, and through holes are formed in the middle frame 303 and are aligned with the openings in the sensor integration module 302.
Here, the screen is used to display information and may include a Liquid Crystal Display (LCD) and a Touch Panel (TP). If the screen includes a touch panel, the screen may be implemented as a touch screen to receive an input signal from a user. The touch panel includes one or more touch sensors to sense touch, slide, and gestures on the touch panel.
The middle frame is used for bearing the screen, and the material of the middle frame comprises metal material or plastic.
Taking fig. 3 as an example, the screen is installed on the middle frame, and the sensor integration module is placed under the middle frame.
Here, it should be noted that, the sensor integrated module is placed under the middle frame, that is, when the screen is a Liquid Crystal Display (LCD), since the LCD includes a backlight source, the information at the screen can be displayed only by the light emitted from the backlight source, and if the sensor integrated module is placed under the screen, the light transmission is blocked. Therefore, for the screen of the LCD, if a sensor that needs to receive light or emit light is placed in the mobile terminal, the sensor can only be placed under the frame at the side of the screen, or placed in the screen, that is, the sensor is inserted between the pixel points of the glass substrate above the backlight source of the LCD. Embodiments of the present disclosure are directed to arrangements in which the sensors are placed under the bezel at the side of the screen.
Further, because the sensor integration module is located below the frame on the side of the screen, and the frame faces the second surface of the middle frame, that is, is located above the middle frame, in order to avoid the obstruction of the existence of the middle frame to the emission and the reception of the light of the sensor integration module, in the embodiment of the present disclosure, a through hole is provided on the middle frame, and the through hole is aligned with the opening on the sensor integration module, so that the light emitted by the light emitting module in the sensor integration module can be emitted to the outside through the through hole on the middle frame after passing through the opening on the protective cover. Correspondingly, external light can reach the opening in the protective sleeve after passing through the through hole in the middle frame, and then passes through the opening to reach the photosensitive surface of the first light receiving module or the second light receiving module in the sensor integrated module.
Therefore, the light rays are transmitted through the through holes in the middle frame, and convenience is provided for the light rays to reach the photosensitive surface of the first type light receiving module or the second type light receiving module from the outside or to reach the outside from the light emitting module.
In some embodiments, fig. 4 is a schematic structural diagram of a mobile terminal according to an exemplary embodiment, as shown in fig. 4, a sensor integration module 402 faces a first side 4031 of a middle frame 403;
the mobile terminal 400 further includes:
a border 404, the border 404 and the screen 401 both facing a second face 4032 of the middle frame 403, the second face 4032 being opposite to the first face 4031;
wherein, there is a gap 405 between the frame 404 and the screen 401, and the gap 405 is aligned with the through hole 406.
As shown in fig. 4, the sensor integration module 402 and the screen 401 are respectively located at two sides of the middle frame 403, and the sensor integration module 402 is not directly corresponding to the screen 401, but the sensor integration module 402 is located at one side of the screen 401, that is, at a position close to the frame in the mobile terminal.
A first surface 4031 of the middle frame 403 refers to a surface toward which the sensor integrated module 402 faces, and a second surface 4032 of the middle frame 403 refers to a surface toward which the screen 401 faces, and as can be seen from fig. 4, the first surface 4031 is opposite to the second surface 4032.
In some embodiments, the first face of the middle frame is parallel to and opposite the second face of the middle frame.
The bezel 404 and the screen 401 are both located on the same side of the middle frame, i.e., as shown in FIG. 4, the bezel 404 and the screen 401 are both facing the second side 4032 of the middle frame 403. Also, when located on the same side of the bezel, there is a gap 405 between the bezel 404 and the screen 401, the gap 405 being aligned with the through hole 406.
Here, the middle frame further includes: and a third face perpendicular to both the first face of the middle frame and the second face of the middle frame, i.e., a vertical face of the middle frame as shown in fig. 4. Here, the first face, the third face, and the second face of the middle frame in combination exhibit a T-shape.
The frame is positioned above the middle frame, faces to the second surface of the middle frame and is positioned on the same horizontal plane with the screen. A gap is arranged between the frame and the screen and is aligned with the through hole. That is, the gap is aligned with the sensor integrated module, so that light emitted by the light emitting module in the sensor integrated module can be emitted out through the through hole in the middle frame and the gap between the frame and the screen after passing through the opening in the protective sleeve. Correspondingly, external light can reach the through hole on the middle frame after passing through the gap between the frame and the screen, and then reaches the opening on the protective sleeve through the through hole, and then passes through the opening to reach the photosensitive surface of the first type light receiving module or the second type light receiving module in the sensor integrated module.
It should be noted that, in some embodiments, the slit is disposed along the extension direction of the long side or the short side of the middle frame.
Here, as shown in fig. 4, since the gap is located between the frame and the screen, and the frame is a frame located around the mobile terminal, the gap includes: a frame on a long side of the mobile terminal, or a frame on a short side of the mobile terminal. Then, when the sensor integrated module is placed under the frame on the long side of the mobile terminal, the gap between the frame and the screen is set along the extending direction of the long side of the middle frame. When the sensor integrated module is placed under the frame on the short side of the mobile terminal, the gap between the frame and the screen is arranged along the extension direction of the short side of the middle frame.
Here, the sensor integrated module located under the border on the short side of the mobile terminal is equivalent to being located at the head or tail of the mobile terminal. Here, since the tail portion may be held by the palm of the user in practical use, which affects the receiving and emitting of light, in some embodiments, the sensor integrated module is located at the head of the mobile terminal when it is located under the frame on the short side of the mobile terminal.
In some embodiments, a screen, comprising: and the display surface deviates from the middle frame.
Here, the display surface facing away from the middle frame is a surface for displaying information, and the user can see the information.
On the display surface, a transparent cover plate covers the gap between the screen and the frame. The material of this transparent cover plate includes: glass or plastic, etc. The transparent cover plate can be a transparent glass cover plate or a transparent plastic cover plate. Here, the transparent cover plate can be favorable to the display of information, also can play the guard action to the screen, prevents that mobile terminal from directly damaging the screen after dropping.
The transparent cover is oriented towards the display surface of the screen. As shown in fig. 4, the transparent cover is located on the display surface of the screen.
Here, because the sensor integrated module is inside mobile terminal, need receive outside light or transmission light to the outside, and transparent cover is located the outside of mobile terminal and is directly by the position that the user contacted, if set up the opening on transparent cover and make light pass through, then can be unfavorable in appearance, and also can make the dust get into because this opening, influence the operation of each inside device of mobile terminal to and influence the life-span, and set up transparent cover then can not appear above-mentioned problem.
In some embodiments, the transparent cover plate is provided with a light-transmitting ink which allows light of the first wavelength and/or the second wavelength to transmit, on the surface facing the display surface, at a position corresponding to the through hole.
Here, the light transmissive ink is a light transmissive material that allows light to pass through the ink to the other side. The light-transmitting ink in the embodiment of the disclosure is also a material which can allow light of a preset waveband to pass through, so that unnecessary light can be filtered, and light entering the first-type light receiving module or the second-type light receiving module can be screened once in advance, thereby providing a basis for collecting specific light later.
When the ink is applied to different scenes, different requirements are required for light collection, and then, light-transmitting materials which enable light rays of different wave bands required by the different scenes to pass through can be added into the ink, so that different light-transmitting requirements are achieved.
When the first type of light receiving module of the sensor integrated module receives infrared light, the light-transmitting ink is ink allowing infrared light to transmit. When the second type of light receiving module of the sensor integrated module receives visible light, the light-transmitting ink is ink allowing visible light to transmit.
In this embodiment, a transparent material capable of transmitting light with 850nm or 940nm wavelength and 550nm wavelength may be added to the ink to realize the transmission of infrared light and visible light.
In the embodiment of the disclosure, the light-transmitting ink can be arranged only at the position corresponding to the through hole on the transparent cover plate, so that part of the cost can be saved. In addition, because the transparent cover plate is also placed above the screen, if the whole transparent cover plate is provided with the light-transmitting ink on the surface facing the display surface, the interference on the information displayed on the screen is also caused, and therefore, the light-transmitting ink is only arranged on the transparent cover plate at the position corresponding to the through hole.
It is noted that in some embodiments, the clear ink may be formed by stacking multiple layers of clear ink. In the stacking of the light-transmitting ink, a tiny gap is formed between every two stacked light-transmitting ink layers, so that light can be refracted between the light-transmitting ink layers and the gap. When printing ink layer covers on the position that corresponds with the through-hole on transparent cover plate, thereby because the angle that the refraction can make thereby the light that gets into the through-hole through printing ink of passing through can change, so, because the refraction effect of printing ink of passing through for the light that gets into will be fixed at certain extent. Then, if more light is desired to enter the sensor integration module, the number of layers of the light-transmitting ink can be increased to increase the refraction angle, which is beneficial to more light entering the sensor integration module of the sensor integration module.
Fig. 5 is a graph showing the transmittance of visible light and infrared light for different light-transmitting inks, and as shown in fig. 5, the light-transmitting ink allowing visible light to transmit has a higher transmittance for visible light with a wavelength of 550nm relative to infrared light with a wavelength of 940nm, while the light-transmitting ink allowing infrared light to transmit has a higher transmittance for infrared light with a wavelength of 940nm relative to visible light with a wavelength of 550 nm.
Since human eyes are most sensitive to light with a wavelength of about 550nm, in some embodiments, a light-transmitting material capable of transmitting light with a wavelength of 550nm may be added to the ink only, so as to satisfy the perception of human eyes on light to the maximum extent. In the current application, the wavelength of the light emitted by the infrared lamp is generally 2 of 850nm and 940nm, and then a light-transmitting material which can transmit the light with the wavelength of 850nm or 940nm is added into the ink.
In some embodiments, the screen includes: a side facing the bezel;
the side face of the screen, the second face of the middle frame, the hole wall of the through hole and the frame are all covered with a light shielding layer.
The light shielding layer is a physical medium made of a light shielding material and used for shielding light.
When the sensor integrated module is applied to the inside of the mobile terminal, if light is emitted from other devices inside the mobile terminal, light emitted from other devices can be transmitted into the sensor integrated module, and the first type light receiving module or the second type light receiving module can be influenced to receive light with respective corresponding wavelengths, so that the detection of ambient light or infrared light is inaccurate. Based on this, the side of the screen, the second surface of the middle frame, the hole wall of the through hole and the frame are all covered by the light shielding layer in the embodiment of the disclosure, so as to isolate other light rays outside the sensor integrated module.
Here, the side of the screen is just covered with the light shading layer due to the fact that the side of the screen faces the light transmission channel corresponding to the sensor integrated module, and the light shading layer can prevent light emitted by the screen from interfering light in the light transmission channel of the sensor integrated module.
The second surface of the middle frame is covered with the light shielding layer due to the fact that the second surface of the middle frame faces the screen, and the influence of light emitted by the screen on the first type light receiving module or the second type light receiving module can be just prevented.
The light shading layer covers the frame, so that when the light emitted by the screen is emitted to the side edge, the light is reflected by the frame and then absorbed by the first type light receiving module or the second type light receiving module of the sensor integrated module, and the effect of the sensor integrated module is influenced.
The light shielding layer is covered on the hole wall of the through hole, so that the light emitted by the light emitting module is prevented from being reflected by the hole wall of the through hole to influence the receiving of the first type light receiving module or the second type light receiving module after being emitted to the hole wall of the through hole.
It should be noted that, after the light emitting module is a light emitting device that emits vertically, due to the impact force of vertical emission, the light receiving module may be impacted, which affects the accuracy of the collected light quantity. At this time, the emitting and receiving in the sensor integrated module can be performed in different periods, that is, when the light emitting module is detected to emit light, the first type light receiving module or the second type light receiving module does not perform light receiving. In this way, interference of transmission with reception can be prevented.
In some embodiments, the area of the through hole is larger than the area of the opening on the sensor integrated module.
Because the sensor integrated module is located inside the mobile terminal, in order to make the effect of receiving and transmitting light better, the diameter of the channel for light conduction from top to bottom on the mobile terminal presents an inverted cone shape from large to small. The length of each position is set in a mode from large to small, external light is facilitated to enter the mobile terminal, collection of a first type of light receiving module or a second type of light receiving module of the sensor integration module is facilitated, and for the light emitting module, the process of emitting light is from small to large, so that light is facilitated to be emitted towards all directions.
The aperture of the through hole can be determined based on the aperture of the position corresponding to the through hole on the transparent cover plate and the aperture of the opening on the sensor integrated module, and after the aperture is determined, the area of the through hole can be determined based on an area determination method.
Here, in consideration of the introduction and emission effects of light, the aperture of the position of the transparent cover plate corresponding to the through-hole may be set between 0.6mm and 1mm, and then the aperture of the through-hole of the corresponding middle frame may be set between 1.5mm and 2 mm.
Fig. 6 is a schematic top view illustrating the size difference in the same direction between the through hole 601 on the transparent cover of the mobile terminal, the through hole 602 on the middle frame, and the sensor integration module 603, where as shown in fig. 6, the aperture of the through hole 601 on the transparent cover is larger than that of the through hole 602 on the middle frame. In this way, an inverted conical layout from top to bottom is achieved.
Here, the width of the through-hole on the middle frame is 0.6mm, the length is a range in which a range of 1mm and a range of 2mm are combined, and the distance between the range of 1mm and the range of 2mm is 1.6 mm. The width of the position that corresponds with the through-hole on the transparent cover plate is 1.6mm, and length includes: the range of 1.5mm and the range of 3mm combined, the distance between the range of 1.5mm and the range of 3mm being 0.6 mm.
In fig. 6, the distance between the transmitting and receiving light path ranges in the aperture of the position 601 corresponding to the through hole on the transparent cover plate is greater than or equal to 0.6mm, and the distance between the transmitting and receiving light path ranges in the aperture of the through hole 602 on the middle frame is greater than or equal to 1.6mm, so that relatively good light receiving and transmitting effects can be achieved.
Fig. 7 is a schematic side view of the position 601 corresponding to the through hole on the transparent cover plate, the through hole 602 on the middle frame, and the sensor integration module 603 in the mobile terminal, which are different in size in the same direction, as shown in fig. 7, the sensor integration module is aligned with the through hole on the middle frame, the light emitting module 604 is located on the left side of the sensor integration module, and corresponds to the range of 1mm of the through hole on the middle frame, and the range of 1mm of the through hole is used for the light emitted by the light emitting module 604 to pass through. The first light receiving module 605 and the second light receiving module 606 are located on the right side of the sensor integrated module, and correspond to the 2mm range of the through hole on the middle frame. There is a preset distance interval between the light emitting module and the light receiving module. Then the distance between the light paths passing through the through holes on the middle frame is 1.6mm, and the distance between the light paths passing through the transparent cover plate is 0.6 mm. Therefore, the width of the mobile terminal and the light receiving and emitting effects are integrated, and a good effect can be obtained as far as possible.
Further, as shown in fig. 7, the thickness of the middle frame is 0.7mm, the distance between the middle frame and the transparent cover plate is 1.4mm, and the distance between the middle frame and the sensor integration module is 0.3mm, so that the smaller thickness of the mobile terminal can be ensured on the basis of obtaining better light receiving and emitting effects as far as possible.
Thus, the embodiment of the disclosure reduces the cost by arranging the sensor integration module which integrates multiple types of sensors together in the mobile terminal. And, in order to cooperate the function realization of sensor integration module, set up the through-hole with the opening of sensor integration module on the center and satisfy the transmission of light, also set up the gap between frame and screen equally, further guarantee the transmission of light outward and introduce inwards. And for better transmission effect and receiving effect, the side of the screen, the second surface of the middle frame, the hole wall of the through hole and the frame are all covered with a light shielding layer, so that the interference of other external light rays on the first type light receiving module or the second type light receiving module is isolated, and the collection effect is optimized. In addition, with the area of through-hole, set up to being greater than the open-ended area on the sensor collection module, can realize from the top down back taper overall arrangement, be favorable to outside back in getting into mobile terminal, the collection of the first type light receiving module or the second type light receiving module of the sensor collection module of being convenient for, to light emission module, the process of penetrating light is then by little to big, then is favorable to light to each direction transmission.
The embodiment of the present disclosure further provides a control method, where the control method may be applied to the mobile terminal in the above embodiment, and the control method includes:
101, using a light emitting module in a sensor integrated module in a mobile terminal to emit light with a first wavelength in a first time period;
102, receiving light rays with a second wavelength in a second time period by using a second type light receiving module in a sensor integrated module in the mobile terminal; wherein the first period is different from the second period.
Here, a plurality of types of optical devices are integrated in the sensor integration module in the mobile terminal, and the sensor integration module has a plurality of functions. However, there may be some interference between different types of optical devices during operation, for example, an optical device emitting infrared light may interfere with the detection of an infrared collector that detects the presence of infrared light in an environment during operation. Therefore, for the optical devices processing the same wave band, the interference can be reduced by the way of time-sharing operation.
For optical devices with different processing bands, because some light emitting modules, for example, vertical cavity surface emitting lasers (Vscel), may generate impact when emitting light, and may affect the reception of surrounding optical devices, in this case, the interference may also be reduced by way of time-division operation.
Here, the embodiment of the present disclosure uses the light emitting module in the sensor integrated module in the mobile terminal to emit the light with the first wavelength in the first period, and controls the second type light receiving module to receive the light with the second wavelength in the second period, so that the emission and the reception can be separated, and the interference between each other in operation is less.
Here, the light emitting module emits the light with the first wavelength in the first period and the second type light receiving module receives the light with the second wavelength in the second period may be controlled to emit the light with the first wavelength in the first period and control the second type light receiving module to receive the light with the second wavelength in the second period under the control of different enable signals.
Therefore, the interference of different types of optical devices in working can be reduced by designing the transmitting and receiving time-sharing way in a mode that the light emitting module in the sensor integrated module in the mobile terminal emits the light with the first wavelength in the first time period and the second type of light receiving module in the sensor integrated module in the mobile terminal receives the light with the second wavelength in the second time period. Thus, even if the sub-bands cannot be completely isolated, they can be separated by the operation of the sub-period. Then, the mobile terminal can achieve better transmitting and receiving effects based on the sensor integration module.
