In one embodiment, the display screen 150 is disposed on the housing 160, and the display screen 150 and the housing 160 enclose a receiving space, in which the optical module and the light guide channel are disposed. Light holes communicated with the accommodating space are respectively arranged on the display screen 150 and the shell 160. The optical module includes a light sensor 140 and an infrared emitter 230.

In actual implementation, the electronic device further includes a motherboard 170. The motherboard 170 is electrically connected to the optical module, i.e. the motherboard 170 is electrically connected to the photo sensor 140 and the infrared emitter 230. Accordingly, the main board 170 may acquire light sensing data of the light sensing sensor 140 or infrared signal related data of the infrared emitter 230, so that a corresponding operation may be performed according to the above data. For example: the main board 170 may determine the ambient light intensity of the electronic device by acquiring the light sensation data, so that the brightness of the display screen 150 may be adjusted according to the ambient light intensity.

Alternatively, the main board 170 may be electrically connected to the light sensor 140 and the infrared emitter 230 by using a flexible circuit board (Flexible Printed Circuit, FPC), or by using a panel or a raised small board, and the embodiment of the present application is not particularly limited.

As shown in fig. 1 to 6, according to the arrangement of different light guide channels, the electronic device provided in the embodiment of the present application may be divided into the following three structures.

1. The electronic device comprises a first light guiding channel 110 and a second light guiding channel 210. The electronic device provided in the embodiment of the application is described in detail below with reference to fig. 1 and 2.

In one embodiment, the light guide channels include a first light guide channel 110 and a second light guide channel 210.

The first light guide channel 110 and the second light guide channel 210 may be integrally formed or may be combined, and the present application is not limited thereto.

As shown in fig. 1, a first light guide channel 110 is disposed in the accommodating space. The first end of the first light guiding channel 110 faces the light sensor 140, and the second end of the first light guiding channel 110 faces the first light transmitting hole 130 on the display screen 150. The second end of the first light guiding channel 110 may extend from the direction perpendicular to the first light transmitting hole 130, and then the position of the first end is adjusted according to the position of the light sensor 140, so that the light emitting surface corresponding to the first end of the first light guiding channel 110 is opposite to the light sensor 140, and thus light can be transmitted from the first light transmitting hole 130 to the light sensor 140 through the first light guiding channel 110. The direction of the arrow in fig. 1 is the light transmission direction.

The first light hole 130 on the display screen 150 may be a through hole with a light transmission effect, that is, the electronic device may receive the ambient light through the first light hole 130 and conduct the ambient light into the accommodating space. The optical module in the accommodating space can also emit the optical signal into the environment through the first light hole 130. The environment in the embodiment of the application refers to the physical environment in which the electronic device is located. The first light holes 130 may be made of transparent glass, a lens for refracting light, or other light-transmitting materials, which are not particularly limited in the present application. The first light holes 130 may be various through holes, for example, circular light holes, square light holes, or light holes with other shapes, which is not particularly limited in the present application.

Alternatively, the relative positions of the first end to the second end of the first light guiding channel 110 may be adaptively designed according to requirements, and the first light guiding channel 110 shown in fig. 1 is only used as an example, and the shape of the first light guiding channel 110 is not particularly limited in the present application. The second end of the first light guide channel 110 is further provided with a first liquid crystal plate 120. The optical path of the first light guide channel 110 can be controlled to be on-off by using the optical rotation characteristic of the liquid crystal.

As shown in fig. 2, a second light guide channel 210 is further disposed in the accommodating space. The first end of the second light guide channel 210 faces the infrared emitter 230, and the second end of the second light guide channel 210 faces the first light transmitting hole 130. The second end of the second light guide channel 210 may extend from the direction perpendicular to the first light transmission hole 130, and then the position of the first end is adjusted according to the position of the infrared emitter 230, so that the light incident surface corresponding to the first end of the second light guide channel 210 is opposite to the infrared emitter 230, and thus the light can be emitted to the outside of the electronic device through the second light guide channel 210 by the infrared emitter 230. The direction of the arrow in fig. 2 is the light transmission direction.

Alternatively, the relative positions of the first end to the second end of the second light guiding channel 210 may be adaptively designed according to the requirements, and the second light guiding channel 210 shown in fig. 2 is only used as an example, and the shape of the second light guiding channel 210 is not particularly limited in the present application. The second end of the second light guide channel 210 is further provided with a first filter 220. The first filter 220 is used for selecting a desired radiation band from the light.

It should be noted that the first liquid crystal wafer 120 and the first optical filter 220 may be disposed at intervals or adjacently, and the first liquid crystal wafer 120 and the first optical filter 220 may operate independently. The light sensor 140 and the infrared emitter 230 may be disposed at intervals or adjacently, and the light sensor 140 and the infrared emitter 230 may operate independently.

According to the electronic equipment provided by the embodiment of the application, through the design of the first light guide channel and the second light guide channel, the functions of the front color temperature sensor and the infrared photosensitive two-in-one sensor can be realized by multiplexing one light sensor and one infrared emission device, and the number, layout area and layout difficulty of the sensors used in the electronic equipment are reduced, so that the cost can be saved, and the power consumption can be reduced.

In one embodiment, in the case where the first microchip 120 is in a light-transmitting state, the optical module is used as at least one of:

A front color temperature sensor; an infrared photosensitive sensor.

Optionally, when the front camera starts to work, the first liquid crystal wafer 120 is controlled to be in a light-transmitting state, an infrared signal can be emitted through the infrared emitter 230 in the optical module via the second light guide channel 210, and the front color temperature data and the infrared photosensitive data can be obtained through the light sensor 140 in the optical module via the first light guide channel 110. Therefore, the optical module can be used as a front color temperature sensor and an infrared photo sensor.

The front-facing color temperature data are color temperature data acquired by a color temperature sensor corresponding to the front-facing camera. Color temperature is one unit of measure representing the inclusion of a color component in a light ray. The color temperature sensor can detect the color temperature of the environment when photographing, so that the color of the photographed picture is more accurate, and meanwhile, aiming at different photographing scenes, the photographed image is optimized in a targeted mode through artificial intelligence and automatic identification, so that more excellent photo effects are achieved.

The infrared light sensor may include an infrared sensor and a photosensitive sensor. The infrared sensor is a sensor for data processing by using infrared rays, and the photosensitive sensor is a sensitive device having a response or conversion function to an external light signal or light radiation. For example: the infrared sensor can receive infrared light reflected by the foreign object to detect whether the foreign object is approaching the electronic equipment, for example, when a user calls, the mobile phone approaches the face of the person, and the screen can be automatically extinguished or unlocked at intervals. The photosensitive sensor is mainly applied to a scene that the electronic equipment can automatically execute a series of functional reactions when light changes, for example, the electronic equipment can automatically adjust the screen brightness in a darker environment.

According to the electronic equipment provided by the embodiment of the application, the first light guide channel and the second light guide channel are arranged in the electronic equipment, so that light can be transmitted from the first light transmission hole of the display screen to the light sensor and the infrared transmitter, and then the liquid crystal sheet is used for controlling the light path on-off of the light guide channel, so that the optical module can realize the functions corresponding to the front color temperature sensor and the infrared photosensitive sensor, the number of devices of the sensor is reduced, and further the cost and the power consumption can be reduced; the layout area can be saved, and the layout difficulty is reduced; furthermore, the internal space of the electronic equipment can be saved, and the stacking difficulty of the internal structure of the electronic equipment is reduced.

2. The electronic device includes a first light guide channel 110, a second light guide channel 210, and a third light guide channel 310. The electronic device provided by the embodiment of the application is described in detail below with reference to fig. 3 and 4.

In one embodiment, as shown in fig. 3 and 4, the light guide channel further includes a third light guide channel 310, a first end of the third light guide channel 310 is opposite to the optical module, and a second end of the third light guide channel 310 is opposite to the second light hole 330 of the housing 160; the second end of the third light guide channel 310 is provided with a second filter 320.

It should be noted that the housing 160 includes a top middle frame and a rear cover. The second light transmitting hole 330 is disposed on the top middle frame of the housing 160.

In this embodiment, the accommodating space is provided with a third light guide channel 310 in addition to the first light guide channel 110 and the second light guide channel 210. The shape, structure and connection manner of the first light guiding channel 110 and the second light guiding channel 210 may be set with reference to the above embodiments, and will not be described herein.

Alternatively, as shown in fig. 3, the first end of the third light guiding channel 310 may be directed towards the light sensor 140 in the optical module, or as shown in fig. 4, the first end of the third light guiding channel 310 may also be directed towards the infrared emitter 230 in the optical module. The second end of the third light guide channel 310 may face the second light transmitting hole 330 of the housing 160. The second end of the third light guide channel 310 may extend from the direction perpendicular to the second light hole 330, and then the position of the first end is adjusted according to the position of the optical module, so that the light emitting surface corresponding to the first end of the third light guide channel 310 is opposite to the optical module, and thus, light may be transmitted from the second light hole 330 to the optical module through the third light guide channel 310, or the optical module may transmit light from the second light hole 330 to the outside of the electronic device through the third light guide channel 310. The direction of the arrows in fig. 3 and 4 is the light transmission direction.

The second light hole 330 on the housing 160 may be a through hole with a light transmission effect, that is, the electronic device may receive ambient light through the second light hole 330 and conduct the ambient light to the inside of the electronic device, and the optical module inside the electronic device may also emit an optical signal into the environment through the second light hole 330. The environment in the embodiment of the application refers to the physical environment in which the electronic device is located. The second light hole 330 may be made of transparent glass, a lens for refracting light, or other light-transmitting materials, which are not particularly limited in the present application. The second light holes 330 may be various through holes, for example, circular light holes, square light holes, or light holes with other shapes, which is not particularly limited in the present application.

It is understood that the second light transmitting holes 330 may be used for emitting and receiving infrared signals. The infrared light emitted by the infrared emitter 230 in the optical module passes through the second light hole 330 to the outside of the electronic device, and is reflected and refracted in a series to enter the second light hole 330, and is received by the light sensor 140 in the optical module.

Alternatively, the relative positions of the first end to the second end of the third light guiding channel 310 may be adaptively designed according to requirements, and the third light guiding channel 310 shown in fig. 3 and 4 is only used as an example, and the shape of the third light guiding channel 310 is not particularly limited in the present application. The second end of the third light guide channel 310 is further provided with a second optical filter 320. The second filter 320 is used for selecting a desired radiation band from the light.

It will be appreciated that, to simplify the structural design and reduce the hardware cost, the third light guide channel 310 in fig. 3 and 4 may be the same light guide channel, i.e. the first end of the third light guide channel 310 may face different optical devices in the optical module, and the second end may be provided with a filter. In practical implementation, the third light guide channel may also be a plurality of light guide channels with independent light guide channels, that is, one end of each of the different light guide channels may face different optical devices in the optical module, and the other end may be provided with one or more optical filters, which is not particularly limited in the present application.

For example: in the case where the third light guide channel comprises two independent light guide channels, the first end of the first sub-channel may be directed towards the optical sensor in the optical module and the second end of the first sub-channel may be directed towards the second light transmission hole; the first end of the second sub-channel may be directed towards an infrared emitter in the optical module, and the second end of the second sub-channel may be directed towards the second light-transmitting aperture; the second ends of the first sub-channel and the second sub-channel are respectively provided with an optical filter.

As shown in fig. 3 and 4, the first light guide channel 110 in fig. 3, the second light guide channel 210 in fig. 4, and the third light guide channel 310 in fig. 3 or 4 may be three different light guide channels in the same electronic device, that is, the first light guide channel 110, the second light guide channel 210, and the third light guide channel 310 each have an independent light guide path. The three light guide channels may be integrally formed or may be combined, and the present application is not limited thereto.

According to the electronic equipment provided by the embodiment of the application, the third light guide channel is arranged on the basis of the first light guide channel and the second light guide channel, and one light sensor and one infrared emitting device are multiplexed, so that all functions of the front color temperature sensor, the infrared photo-sensitive two-in-one sensor and the top infrared remote control sensor can be realized at the same time, the cost is saved, the power consumption is reduced, and the number of devices and the layout area required by the sensors are reduced.

a front color temperature sensor; an infrared photosensitive sensor;

The optical module is used as an infrared remote control sensor in the case that the first microchip 120 is in a light-shielding state.

Optionally, when the front camera starts to work, the first liquid crystal wafer 120 is controlled to be in a light-transmitting state, and then an infrared signal can be emitted to the outside of the electronic device through the second light guide channel 210 by the infrared emitter 230 in the optical module; and acquires the front color temperature data and the infrared photosensitive data through the first light guide channel 110 by the light sensor 140 in the optical module. Therefore, the optical module can be used as a front-end color temperature sensor and an infrared photosensitive sensor.

Optionally, when the front camera stops working, the first liquid crystal wafer 120 is controlled to be in a shading state. Since the second light transmitting hole 330 and the third light guiding channel 310 are further provided, the top infrared signal may be emitted to the electronic device through the third light guiding channel 310 by the infrared emitter 230 and may be received through the third light guiding channel 310 by the light sensing sensor 140. Thus, the optical module can be used as a top infrared remote control sensor. At the moment, the optical module not only can realize the infrared remote control function, but also can adjust the infrared remote control distance through the duty ratio information of the infrared light received by the top so as to realize the infrared remote control learning function.

The infrared remote control sensor can transmit infrared remote control data to a remote controlled party, and the remote controlled party can receive the infrared remote control data and return generated feedback data to the infrared remote control sensor. For example: the mobile phone can send infrared remote control data to the air conditioner and can control the air conditioner.

According to the electronic equipment provided by the embodiment of the application, the third light guide channel is arranged on the basis of the first light guide channel and the second light guide channel, so that light can be transmitted to the light sensor and the infrared emitter from the second light transmission hole of the shell, and the optical filter is used for selecting a required radiation wave band, so that the optical module can realize the functions corresponding to the infrared remote control sensor, the front color temperature sensor and the infrared photosensitive sensor, the number of devices of the sensor is reduced, and further the cost and the power consumption can be reduced; the layout area of the sensor can be saved, and the layout difficulty of the sensor is reduced; furthermore, the internal space of the electronic equipment can be saved, and the stacking difficulty of the internal structure of the electronic equipment is reduced.

The second end of the fifth light guiding channel 610 may extend from the direction perpendicular to the third light transmitting hole 530, and then the position of the first end is adjusted according to the position of the infrared emitter 230, so that the light incident surface corresponding to the first end of the fifth light guiding channel 610 is opposite to the infrared emitter 230, and thus the light can be emitted to the outside of the electronic device through the fifth light guiding channel 610 by the infrared emitter 230. The direction of the arrow in fig. 6 is the light transmission direction.

Alternatively, the relative positions of the first end to the second end of the fifth light guiding channel 610 may be adaptively designed according to the requirements, and the fifth light guiding channel 610 shown in fig. 6 is only used as an example, and the shape of the fifth light guiding channel 610 is not particularly limited in the present application. The second end of the fifth light guiding channel 610 is further provided with a third optical filter 620. The third filter 620 is used for selecting a desired radiation band from the light.

It is understood that the second liquid crystal wafer 520 and the third filter 620 may be disposed at intervals or adjacently, and the second liquid crystal wafer 520 and the third filter 620 may operate independently. The light sensor 140 and the infrared emitter 230 are disposed at a distance or adjacently, and the light sensor 140 and the infrared emitter 230 may operate independently.

It should be noted that, the first light guiding channel 110 in fig. 5, the second light guiding channel 210 in fig. 6, the third light guiding channel 310 in fig. 5 or fig. 6, and the fourth light guiding channel 510 in fig. 5 and the fifth light guiding channel 610 in fig. 6 may be five different light guiding channels in the same electronic device, that is, the first light guiding channel 110, the second light guiding channel 210, the third light guiding channel 310, the fourth light guiding channel 510 and the fifth light guiding channel 610 all have independent light guiding paths. The five light guide channels may be integrally formed, or may be combined, and the present application is not limited thereto.

According to the electronic equipment provided by the embodiment of the application, the fifth light guide channel and the sixth light guide channel are respectively arranged on the basis of the first light guide channel, the second light guide channel and the third light guide channel, and one light sensor and one infrared emitting device are multiplexed, so that all functions of five sensors including a rear color temperature sensor, a laser ranging sensor, a front color temperature sensor, an infrared light-sensitive two-in-one sensor and a top infrared remote control sensor can be simultaneously realized, and the cost and the power consumption can be reduced, and the number of devices and the layout area required by the sensors can be reduced.

In one embodiment, the optical module is used as an infrared remote control sensor in the case where the first microchip 120 is in a light-shielding state and the second microchip 520 is in a light-shielding state;

in the case that the first microchip 120 is in a light-transmitting state and the second microchip 520 is in a light-shielding state, the optical module is used as at least one of the following:

a front color temperature sensor; an infrared photosensitive sensor;

In the case that the first microchip 120 is in a light-shielding state and the second microchip 520 is in a light-transmitting state, the optical module is used as at least one of the following:

a rear color temperature sensor; a laser ranging sensor.

Optionally, when the front camera and the rear camera stop working, the first liquid crystal wafer 120 and the second liquid crystal wafer 520 are controlled to be in a light shielding state. Since the second light transmitting hole 330 and the third light guiding channel 310 are further provided, the top infrared signal may be emitted through the third light guiding channel 310 by the infrared emitter 230 and may be received through the third light guiding channel 310 by the light sensor 140. Thus, the optical module can be used as a top infrared remote control sensor. At this time, the optical module not only can realize the infrared remote control function, but also can adjust the infrared remote control distance through the duty ratio information of the infrared light received at the top so as to realize the infrared remote control learning function.

Optionally, when the rear camera stops working, the second liquid crystal wafer 520 is controlled to be in a shading state. Except that the optical module is used as an infrared remote control sensor to control the first liquid crystal wafer 120 to be in a shading state, the rest time can control the first liquid crystal wafer 120 to be in a light transmission state. In the case where the first microchip 120 is in a light-shielding state and the second microchip 520 is in a light-transmitting state, the front infrared signal may be emitted through the second light guide channel 210 by the infrared emitter 230, and the front color temperature data and the infrared photo-sensitive data may be acquired through the first light guide channel 110 by the photo-sensor 140. Therefore, the optical module can be used as a front color temperature sensor and an infrared photo sensor.

Alternatively, when the rear camera starts to work, the first liquid crystal wafer 120 and the second liquid crystal wafer 520 can be controlled to be in an alternating light transmission state, and corresponding light sensation data can be obtained in respective light transmission time, that is, time division multiplexing of the front light path and the rear light path is realized. At this time, the optical module can operate in two states:

state 1: when the front color temperature data and the front infrared photosensitive data need to be read, the first liquid crystal wafer 120 is controlled to be in a light transmission state, and the second liquid crystal wafer 520 is controlled to be in a light shielding state.

State 2: in the case where the rear camera starts to operate, for example, when the rear camera views and focuses, it is necessary to read the rear color temperature data and the laser ranging data. At this time, the second liquid crystal wafer 520 is controlled to be in a light-transmitting state, the first liquid crystal wafer 120 is controlled to be in a light-shielding state, and the external ambient light and the infrared reflected light can enter the light sensor 140 through the third light transmitting hole 530. When the infrared emitter does not emit infrared light, the light sensor 140 receives external ambient light information through the fifth light guide channel 610, and the function corresponding to the rear color temperature sensor is realized. When it is recognized that the infrared emission light encounters the target object and is reflected back to the light sensor 140 through the fourth light guide channel 510, the distance between the electronic device and the target object can be obtained by calculating the time interval between the emission and the reception, and the function corresponding to the laser ranging sensor can be realized.

Alternatively, multiplexing of the front-end and rear-end multiple light sensor functions can be achieved by controlling the interval time of state 1 and state 2 switching.

The rear color temperature data are color temperature data acquired by a color temperature sensor corresponding to the rear camera. The laser ranging data are data collected by a laser ranging sensor. The laser ranging sensor can measure the position, displacement and other changes of the measured object, and is mainly applied to measuring the geometric quantities such as the displacement, thickness, vibration, distance, diameter and the like of the detected object.

According to the electronic equipment provided by the embodiment of the application, the fifth light guide channel and the sixth light guide channel are respectively arranged on the basis of the first light guide channel, the second light guide channel and the third light guide channel, so that light can be transmitted to the light sensor and the infrared transmitter from the third light transmission hole, and then the liquid crystal sheet is used for controlling the on-off of the light path, so that the optical module can realize the functions of the infrared remote control sensor, the front color temperature sensor, the infrared photosensitive sensor, the rear color temperature sensor and the laser ranging sensor, the number of devices of the sensor is reduced, and further the cost and the power consumption can be reduced; the layout area can be saved, and the layout difficulty is reduced; furthermore, the internal space of the electronic equipment can be saved, and the stacking difficulty of the internal structure of the electronic equipment is reduced.

In one embodiment, in the case where the first light-transmitting hole 130 receives 1300nm infrared light, the first filter filters 940nm infrared light, the second filter filters 1300nm infrared light, and the third filter filters 1300nm infrared light.

Alternatively, in case the first light-transmitting hole 130 receives 1300nm infrared light, the first filter filters 940nm infrared light, the second filter filters and the third filter filters 1300nm infrared light.

According to the electronic equipment provided by the embodiment of the application, the required infrared light can be obtained through the optical filter, so that the display screen is protected.

In one embodiment, a first polarizer is disposed under the first liquid crystal wafer 120 and a second polarizer is disposed under the second liquid crystal wafer 520.

Optionally, the polarizers are provided at the lower ends of the first liquid crystal wafer 120 and the second liquid crystal wafer 520, and then the initial polarizer angle can be set according to the practical application requirement, so as to control the liquid crystal wafer to be in a light-transmitting state or a light-shielding state.

Alternatively, besides the liquid crystal sheet for controlling the on-off of the optical path, electrochromic film materials may be used for controlling the on-off of the optical path, and the application is not particularly limited.

According to the electronic equipment provided by the embodiment of the application, the polarizer is arranged below the liquid crystal sheet, so that the on-off of a light path can be controlled rapidly.
