The light sensor 30 can convert the light intensity into a light sensing signal in the form of a digital signal after sensing the light intensity output from the light output end 23. The mobile terminal 100 is facilitated to further analyze the light sensing signal. The light sensor 30 can be fixed on any fixed structure in the housing 10, and the light sensor 30 is usually fixed on a circuit board PCB, and in some embodiments, the light sensor 30 can also be fixed on a flexible circuit board FPC, and then connected with the PCB through an electrical device structure and outputs a photosensitive signal.

The processor 110 is electrically connected to the light sensor 30, and the processor 110 is configured to receive the light sensing signal and then calculate the ambient light intensity of the mobile terminal 100 based on the received light sensing signal. It can be understood that, when the mobile terminal 100 is in a scene with a uniformly distributed light source, the light intensity difference between the first outer surface 11 and the second outer surface 12 is not large, and the light intensity formed by converging the light collected by the first light guide column 21 and the second light guide column 22 is close to a double value of the light intensity of the real environment. At this time, the light sensing data collected by the mobile terminal 100 through the light sensor 30 may more accurately reflect the current ambient light intensity.

However, when the mobile terminal 100 is in a scene with an uneven light source distribution, such as a backlight scene or a floor lamp scene, a large difference in the intensity of light sensed by each of the first outer surface 11 and the second outer surface 12 is generated. Particularly, in the case of the prior art, where the light-sensitive sensor is only disposed on the first outer surface 11 or the second outer surface 12, the intensity of the light sensed by the light-sensitive sensor may not accurately reflect the current real ambient light state. For example, when the light of the first outer surface 11 is significantly weaker than that of the second outer surface 12, and the light sensor 30 is only disposed on the first outer surface 11, the mobile terminal 100 adapts its functions of displaying, photographing, etc. based on the weaker light intensity. At this time, because of the deviation between the sensed light intensity and the real scene, the phenomena of low display brightness, short photographing exposure time and the like are easily caused, and the user experience is influenced.

The mobile terminal 100 of the present application can more accurately reflect the intensity of the ambient light in the current scene because the light intensities in two opposite directions of the first outer surface 11 and the second outer surface 12 are collected at the same time. Subsequently, when the mobile terminal 100 adapts its functions such as display, shooting based on the light intensity of the real scene, better display effect can be obtained or a more accurate photo of exposure can be shot, which improves the user experience. In addition, the mobile terminal 100 can sense the light intensity in two directions of the first outer surface 11 and the second outer surface 12 at the same time only by the arrangement of one light sensor 30, so that the cost of the mobile terminal 100 is saved.

The mobile terminal 100 according to the embodiment of the present disclosure may be an intelligent device with a display function, such as a tablet computer, a mobile phone, an electronic reader, a remote controller, a notebook computer, a network television, and a wearable device. The processor 110 may be a Central Processing Unit (CPU). Alternatively, the processor 110 may also be a main processor of the mobile terminal 100, and the processor 110 may be further configured to control various aspects of operations of the mobile terminal 100, such as displaying, photographing, talking, and program running, in addition to receiving the light sensing signal and calculating the light intensity. Or the Processor 110 may also be another general-purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, a discrete hardware component, etc., where the Processor 110 may be electrically connected to a main Processor of the mobile terminal 100 to implement the functions of adapting the display, photographing, etc. of the mobile terminal 100 based on the currently sensed ambient light intensity.

Fig. 4 illustrates a flowchart of a mobile terminal control method according to the present application. The mobile terminal 100 related to the control method, as also described above, includes a housing 10, a light guide assembly 20, and a light sensor 30. Wherein the housing 10 comprises a first outer surface 11 and a second outer surface 12 which are opposite to each other, the light guide assembly 20 comprises a first light guide 21 arranged towards the first outer surface 11, a second light guide 22 arranged towards the second outer surface 12, and a light output end 23 arranged towards the light sensor 30, the method comprises the following steps:

s10, receiving the light sensing signal sensed by the light sensor 30 from the light output end 23;

specifically, as shown in the above-mentioned mobile terminal 100, because the first outer surface 11 and the second outer surface 12 are two opposite outer surfaces of the housing 10, the light sensing assembly 20 can collect the ambient light along the direction of the first outer surface 11 through the first light guiding pillar 21, and can collect the ambient light along the direction of the second outer surface 12 through the second light guiding pillar 22. After the light rays of the first light guide column 21 and the second light guide column 22 are converged, the light rays are output to the light ray sensor 30 corresponding to the light ray output end 23 through the light ray output end 23. The light sensor 30 can convert the intensity of the light sensed from the light output end 23 into a light sensing signal.

S20, based on the distance from the first light guide 21 to the light output end 23 and the distance from the second light guide 22 to the light output end 23, the light sensing signals are weighted and averaged to calculate the ambient light intensity of the mobile terminal 100.

Specifically, the light may be attenuated in the propagation path in the process of propagating through the first light guide pillar 21 to the light output end 23 and in the process of propagating through the second light guide pillar 22 to the light output end 23. Because the shape of the light guide assembly 20 is relatively fixed, when the mobile terminal 100 is controlled by using the control method, the distance from the first light guide pillar to the light output end 23, or the distance that the light in the direction of the first outer surface 11 travels from the first light input end 211 to the light output end 23, can be calculated first; and calculating the distance from the second light guide 22 to the light output end 23, that is, the distance traveled by the light in the direction of the second outer surface 12 from the second light input end 221 to the light output end 23. Then, the loss of the light collected by the first light guide pillar 21 when the light is transmitted to the light output end 23 and the loss of the light collected by the second light guide pillar 22 when the light is transmitted to the light output end 23 are counted according to the calculation result, the photosensitive signals are weighted and averaged, and the ambient light intensity of the mobile terminal 100 is calculated.

Similar to the effect of the mobile terminal 100 described above, the mobile terminal control method of the present application is developed based on the mobile terminal 100 described above. By collecting light on two opposite outer surfaces of the mobile terminal 100, respectively, and calculating the intensity of the collected light of the mobile terminal 100 by weighted average, the real light intensity in the environment can be sensed more accurately. When functions such as display or photographing of the mobile terminal 100 are subsequently controlled, more accurate light intensity can be provided as a reference, a display effect is improved or clearer photos are obtained, and the use experience of a user on the mobile terminal 100 is improved.

Referring to fig. 5, the mobile terminal 100 generally further includes a display 112 for displaying images, wherein the display 112 is disposed on the first outer surface 11 to form a display area 15 on the first outer surface 11. It will be appreciated that the display screen 112 corresponds to the display unit 106 shown in FIG. 1. The first transparent region 13 is disposed at the periphery of the display region 15. That is, in this embodiment, the first light guiding pillar 21 of the light guiding assembly 20 is disposed at the periphery of the display area 15, and collects light from the area of the first outer surface 11 outside the display area 15, so as to prevent the light emitted by the display screen 112 when displaying images from being transmitted to the light output end 23 to interfere with the sensing of the ambient light of the light sensor 30 after being collected by the first light guiding pillar 21.

In another embodiment, fig. 5 further includes a first transparent region 13 ', and the first transparent region 13' is further disposed in the display region 15. At this time, since the first outer surface 11 does not need to specially provide a light-transmitting region for the first light-transmitting region 13' outside the display region 15, the area ratio of the display region 15 in the first outer surface 11 can be enlarged, that is, a higher screen ratio of the mobile terminal 100 is realized. At this time, the processor 110 needs to obtain the display brightness of the display area 15 in the corresponding first transparent area 13', and then calculate the ambient light intensity of the mobile terminal 100 based on the display brightness and the light sensing signal. It is understood that the processor 110 may directly obtain the display brightness information of the display screen 112 at the position corresponding to the first light-transmitting area 13' when controlling the display of the display screen 112. Then, the influence of the display brightness of the area on the light brightness of the light output end 23 through the first light guide pillar 21 is calculated based on the display brightness of the area, and the influence of the display brightness at the first light transmission area 13' is subtracted from the brightness information obtained by the light sensor 30, so that the effect of calculating the real environment light intensity of the mobile terminal 100 can be achieved.

According to an embodiment, the mobile terminal 100 of the present application may further include a plurality of light guide assemblies 20, and each light guide assembly 20 further includes a corresponding light sensor 30, that is, the present application further includes a plurality of light guide assemblies 20 and light sensors 30 with the same number. Each light guide assembly 20 is correspondingly provided with a light sensor 30, and a plurality of light guide assemblies 20 are arranged in the housing 10 at intervals. Correspondingly, the number of the first light-transmitting areas 13 and the second light-transmitting areas 14 is also multiple, and the first light-transmitting areas and the second light-transmitting areas are used for matching with the multiple light guide assemblies 20 to collect light. At this time, as shown in fig. 5, a method of setting the interval between the first light-transmitting region 13 and the other first light-transmitting region 13' may be used. In this embodiment, by setting the plurality of light guide assemblies 20, light can be collected from different positions of the mobile terminal 100, so that the phenomenon that the ambient light intensity cannot be accurately sensed due to the fact that a part of the light guide assemblies 20 are held by hands or blocked by obstacles or the like can be avoided. Although the mobile terminal 100 of the present application has provided the plurality of light guide assemblies 20 and the plurality of light sensors 30, the light intensity of the mobile terminal 100 in two opposite directions is still sensed by one light sensor 30, and the cost-saving effect is still achieved.

In the embodiment where the mobile terminal 100 further includes the display 112, after "performing weighted average on the light-sensitive signals to calculate the ambient light intensity of the mobile terminal 100" in step S20, the method for controlling the mobile terminal further includes:

s30, adjusting the brightness of the display screen 112 based on the ambient light intensity of the mobile terminal 100.

It is understood that, after accurately sensing the light intensity in the current environment, the mobile terminal 100 may correspondingly adjust the display brightness of the display screen 112 based on the more accurate light intensity sensing, so that the user can better observe the picture displayed by the display screen 112.

It can be understood that, for some backlight scenes, the light intensities on the two sides of the first outer surface 11 and the second outer surface 12 of the mobile terminal 100 are different, and the mobile terminal 100 can sense the light intensity of the current environment where the mobile terminal 100 is located more accurately because the light in the direction of the first outer surface 11 and the light in the direction of the second outer surface 12 are collected at the same time, so that the problem that the display brightness of the display screen 112 is too low, which may be caused under the scenes such as backlight scenes, and the adverse phenomenon that the user difficultly observes the picture displayed by the display screen 112 is avoided.

In contrast to the embodiment shown in fig. 5, the scheme that the first light-transmitting region 13' is disposed below the display screen 112, that is, the scheme that the first light guide bar 21 is further disposed below the display screen 112, as shown in fig. 11, in step S20, "performing weighted average on the light-sensitive signals to calculate the ambient light intensity of the mobile terminal 100" may further include the following sub-steps:

s21a, acquiring real-time display brightness of the display screen 112 corresponding to the area of the first light guide column 21;

s22a, calculating the ambient light intensity of the mobile terminal 100 based on the weighted average of the display brightness and the light sensing signal.

It is understood that, at this time, similar to the above-mentioned scenario, the processor 110 may directly obtain the display brightness information of the display screen 112 at the position corresponding to the first light-transmitting area 13' when controlling the display screen 112 to display. Then, the influence of the display brightness of the area on the light brightness of the light output end 23 through the first light guide pillar 21 is calculated based on the display brightness of the area, and then the influence of the display brightness at the first light transmission area 13' is subtracted from the brightness information obtained by the light sensor 30, that is, the effect of calculating the real ambient light intensity of the mobile terminal 100 can also be achieved after weighted averaging.

In one embodiment, the second outer surface 12 is made of a light-transmissive material, and the second light-transmissive region 14 can be disposed at any position of the second outer surface 12. The second light-transmitting region 14 may be disposed at a position corresponding to the first light-transmitting region 13 to reduce the volume occupied by the light guide assembly 20 in the housing 10. Referring to the embodiment of fig. 7, the second outer surface 12 can also be made of an opaque material, in which case the second transparent region 14 is configured as a transparent lens 141 embedded in the second outer surface 12. The second light guide pillar 22 collects the ambient light in the direction of the second outer surface 12 through the transparent lens 141. The transparent lens 141 is preferably provided with a color and material corresponding to the color and material of the second outer surface 12 to improve the uniformity of the appearance of the mobile terminal 100.

Referring to fig. 8, the mobile terminal 100 further includes a camera module 120, and the camera module 120 is disposed near the second outer surface 104 and is used for capturing an external image through the second outer surface 12. At this time, the second outer surface 12 is further provided with a third light-transmitting area 16 corresponding to the position of the camera module 120, and the camera module 120 collects an external image through the third light-transmitting area 16. The second transparent region 14 can be disposed within the third transparent region 16. Because the color of the camera module 120 is usually different from the color of the second outer surface 12, and the camera module 120 is provided with a lens, a flash, and the like, a specific appearance effect is formed in the third light-transmitting area 16. The second transparent area 14 is disposed in the third transparent area 16, so that the appearance consistency of the rest portions of the second outer surface 12 except the third transparent area 16 is not damaged, and the third transparent area 16 and the second transparent area 14 having relatively unique appearance are integrally disposed, thereby ensuring the overall appearance consistency of the mobile terminal 100.

Referring to fig. 9, the mobile terminal 100 is further provided with an electrochromic layer 50. In the embodiment of FIG. 9, the electrochromic layer 50 is located between the first light-transmitting regions 13 and the first light guide posts 21. In other embodiments, the electrochromic layer 50 can also be disposed between the second light-transmitting region 14 and the second light guide 22, or the electrochromic layer can be disposed between the first light-transmitting region 13 and the first light guide 21, and between the second light-transmitting region 14 and the second light guide 22. The processor 110 is also electrically connected to the electrochromic layer 50 for controlling the electrochromic layer 50 to change color periodically.

The electrochromic layer 50 has a function of displaying different colors according to a change of an input voltage, and when ambient light enters the first light guide pole 21 and/or the second light guide pole 22 through the electrochromic layer 50, the light transmittance thereof is also different based on a difference in color of the electrochromic layer 50. Therefore, in the process of controlling the electrochromic layer 50 to change color periodically by the processor 110, the light sensing signal sensed by the light sensor 30 is also in the form of periodic variation. The processor 110 may derive the ratio of the light collected by the first light guide 21 or the second light guide 22 provided with the electrochromic layer 50 to the light intensity in the whole photosensitive signal based on the variation amplitude of the photosensitive signal. Further, the ratio of the light collected by the first light guide 21 to the light collected by the second light guide 22 in the light sensing signal is derived. It will be appreciated that the processor 110 may thus deduce the intensity of the ambient light in the direction of the first outer surface 11 and the intensity of the ambient light in the direction of the second outer surface 12 in the environment in which the mobile terminal 100 is located.

Alternatively, the processor 110 may adjust the display brightness of the display screen 112 or adjust the exposure time of the camera module 120 based on the difference between the light beams in two different directions, so that the mobile terminal 100 can provide a better display effect or a better shooting effect. It should be noted that, when the electrochromic layer 50 is disposed between the first light guide 21 and the first light transmission region 13 and between the second light guide 22 and the second light transmission region 14, it is also necessary to control the color changing periods of the electrochromic layer 50 at two different positions to be different, so as to distinguish the light collected by the first light guide 21 from the light collected by the second light guide 22.

The embodiment of fig. 9 corresponds to the control method of the mobile terminal of the present application, and may be expressed as the method embodiment shown in fig. 10: step S10 "receiving the light sensing signal sensed by the light sensor 30 from the light output end 23", further includes:

s10b, controlling the electrochromic layer 50 to change color periodically, and receiving a photosensitive signal which changes periodically;

then, step S20 "calculate the ambient light intensity of the mobile terminal 100 by performing a weighted average on the light sensing signals based on the distance from the first light guide bar 21 to the light output end 23 and the distance from the second light guide bar 22 to the light output end 23", further includes:

s20b, distinguishing a first ambient light intensity of the first outer surface 11 region from a second ambient light intensity of the second outer surface 12 region based on the periodically changing photosensitive signal, the distance from the first light guide 21 to the light output end 23, and the distance from the second light guide 22 to the light output end 23.

Specifically, the above method embodiments are similar to the embodiments of the mobile terminal 100 of the present application, and the processor 110 controls the periodic color change of the electrochromic layer 50 to achieve the effect of periodically changing the photosensitive signal. Then, the processor 110 calculates the influence of the electrochromic layer 50 on the photosensitive signal and the proportion of the influence in the photosensitive signal by respectively comparing the periodic variation law of the photosensitive signal based on the distance from the first light guide pillar 21 to the light output end 23 and the distance from the second light guide pillar 22 to the light output end 23, and further distinguishes the first ambient light intensity in the first outer surface 11 region and the second ambient light intensity in the second outer surface 12 region.

Alternatively, for the embodiment provided with the camera module 120, after the step S20b "distinguishing the first ambient light intensity of the first outer surface 11 region and the second ambient light intensity of the second outer surface 12 region based on the periodically changing photosensitive signal, the distance from the first light guide 21 to the light output end 23, and the distance from the second light guide 22 to the light output end 23", the method may further include the following steps:

s30b, adjusting the operating parameters of the camera module 120 based on the first ambient light intensity and the second ambient light intensity.

Specifically, after the first ambient light intensity and the second ambient light intensity are determined, it may be determined that the mobile terminal 100 is currently in the front light environment or the backlight environment. Therefore, in the process of controlling the camera module 120 to photograph, the working parameters of the camera module 120, such as the HDR mode, the exposure duration and other parameters, can be adjusted correspondingly, so as to ensure that the working parameters of the camera module 120 match the light conditions of the current scene, improve the quality of the photograph photographed by the camera module 120, and further improve the user experience.
