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.

Fig. 1 is an exploded view of a terminal according to an exemplary embodiment. The terminal may be a mobile terminal such as a mobile phone, a tablet computer, a palm top computer, an e-book reader, a wearable device, etc.

As shown in fig. 1, the terminal includes a center housing 10, a front panel 20, a back panel 30, a first display screen assembly 40, a second display screen assembly (not shown), and an optical sensor; wherein the optical sensor includes a first optical sensor and a second optical sensor.

The front panel 20 and the back panel 30 are respectively disposed on both sides of the center frame case 10.

The first display screen assembly 40 is disposed on the front panel 20, and the second display screen assembly is disposed on the back panel 30.

Referring collectively to fig. 2, a schematic diagram of a first display screen assembly is illustrated. The first display screen assembly includes a first cover glass 41 and a first display panel 42. The first display panel 42 is disposed below the first cover glass 41, and a first gap 43 is formed between the first display panel 42 and the middle frame casing 10. Illustratively, the diameter of the first gap portion may be 0.1 to 1 mm.

Referring to fig. 2 in combination, the first optical sensor 50 is located below the first cover glass 41, and the sensing surface 51 of the first optical sensor 50 faces the front panel front area and is opposite to the first gap portion 43.

Optionally, the first optical sensor may be located below the cover glass, or may be located below the first display panel. When the first optical sensor is positioned under the first display panel, the first display screen assembly may be formed as a full screen.

Referring collectively to fig. 3, a schematic diagram of a second display screen assembly is illustrated. The second display screen assembly includes a second cover glass 61 and a second display panel 62; the second display panel 62 is disposed below the second cover glass 61, and the sensing surface 71 of the second optical sensor 70 faces the front area of the back panel.

Fig. 3 illustrates only a structure in which the second optical sensor is located under the second cover glass, and in other exemplary embodiments, the second cover glass may not cover the second optical sensor. In addition, the second optical sensor may be positioned below the second display panel. The embodiments of the present disclosure are not limited thereto.

It should be noted that, the structures of the first display screen assembly and the second display screen assembly may be the same or different, and this is not limited in this disclosure.

The optical sensor may be any one of: a color temperature sensor, a brightness sensor, a distance sensor, a color sensor, an ultraviolet sensor. Wherein the color temperature sensor is a sensor capable of detecting a color temperature of the ambient light. The brightness sensor is a sensor which can sense the brightness of the ambient light and convert the ambient light into a usable output signal. The distance sensor is a sensor capable of detecting a distance between an object and a terminal according to ambient light. The color sensor can acquire the spectrum of the ambient light in the area in front of the screen. The ultraviolet sensor refers to a sensor capable of detecting the intensity of ultraviolet rays of ambient light.

In the embodiments of the present disclosure, the optical sensor is taken as an example of a luminance sensor.

Optionally, with reference to fig. 2 in combination, the terminal further includes: and a first diffusion layer 80 located in the first gap portion 43. Through the first diffusion layer 80, the incident light of the environment can be scattered, so that the optical sensor 50 is no longer sensitive to the light sensing angle, and sudden change of light environment parameters caused by angle change of the light source of the environment light of the optical sensor 50 is avoided.

Optionally, the first diffusion layer is a diffusion sheet or a light-equalizing ink. The diffusion sheet contains a plurality of chemical particles as scattering particles distributed between resin layers of a base material of the diffusion sheet. In addition, the first diffusion layer can be made of other materials with the function of scattering ambient incident light.

In addition, the above terminal may further include a second diffusion layer located in the second gap portion. The second diffusion layer is a diffusion sheet or a light-homogenizing ink. The first diffusion layer and the second diffusion layer operate on the same or similar principles.

The principle of operation of the first diffusion layer will now be described in detail with reference to fig. 4. Taking the first display screen assembly as an example, when light passes through the first display screen assembly, the first diffusion layer and the first display screen assembly are made of different materials, so that the light is refracted, reflected and scattered on the interface between the first diffusion layer and the first display screen assembly.

When the diffusion sheet is not arranged at the terminal, the ambient light source is in theta₁Is incident on the terminal end and is refracted at the interface of the first display screen assembly 20 and the diffuser plate 80 and directed towards the first optical sensor 50 at an angle gamma. Its refractive index n₁The following formula can be used to calculate:

when the terminal is provided with a diffuser, the ambient light source is at θ₂Is incident on the terminal end and is refracted at the interface of the first display screen assembly 20 and the diffuser plate 80 and directed towards the first optical sensor 50 at an angle gamma. Its refractive index n₂The following formula can be used to calculate:

after the first diffusion layer is arranged, the refractive index n₂Greater than n₁And is thus sin θ₂Greater than sin theta₁It is further known that the FOV (Field of View, Field angle) β is greater than α.

From the above, when the diffusion sheet is disposed at the terminal, the FOV can be enlarged by optical scattering, so that the ambient light radiation area is increased. In addition, after the incident ambient light source is diffused by the first diffusion layer, the light source can be more uniform, a surface light source with uniform light is formed, further, the optical sensor is not sensitive to the photosensitive angle any more, and sudden change of light environment parameters caused by angle change of the ambient light source is avoided.

Alternatively, the thickness of the first diffusion layer described above may affect the angle of view of the optical sensor.

With combined reference to fig. 5, a schematic diagram illustrating the effect of the first diffuser layer thickness on the FOV is illustrated.

As shown in fig. 5, the abscissa is FOV and the ordinate is the received energy value ratio, which is the ratio of the ambient light intensity value of different FOVs to the ambient light intensity value when the FOV is 0 degrees. In the figure, the diffusion curve (a) represents an ideal diffusion curve; the diffusion curves (b), (c), and (d) correspond to the first diffusion layers of different thicknesses, respectively, and the thicknesses of the first diffusion layers are sequentially decreased.

It can be seen that the thicker the first diffusion layer is, the better the diffusion effect of the first diffusion layer on the ambient light source is. In addition, it can be seen that when the FOV is 0 degrees, the received energy value ratio of the optical sensor is the largest, that is, the ambient light source is perpendicular to the sensing surface of the optical sensor; when the FOV is 90 degrees or-90 degrees, the received energy value ratio of the optical sensor is 0, namely the ambient light source is parallel to the sensing surface of the optical sensor; during the course of increasing the absolute value of the FOV from 0 to 90 degrees, the received energy value is gradually reduced in proportion, i.e., the ambient light intensity received by the optical sensor is gradually decreased.

Alternatively, referring to fig. 6 in combination, the first optical sensor 50 includes a light blocking sleeve 52, a light receiver 53, and a light processing chip 54. The light receiver 53 faces the first gap portion 43, the light blocking sleeve 52 covers the light receiver 53, and the light processing chip 54 is coupled to the light receiver 53.

The light blocking sleeve is used for blocking the entering of environmental dust so as to protect the optical sensor. The light receiver is used for receiving the ambient light source, and the light receiver may be a PD (Photo Diode). The optical processing chip is used for carrying out a series of processing on the received signals so as to form the ambient light parameters.

Optionally, the optical processing chip includes an AFM (Analog Front End), an ADC (Analog digital Converter), and a Micro Control Unit MCU (Micro Control Unit); wherein, AFM, ADC and MCU are coupled in turn.

The AFE may process the received analog signal, such as signal amplification, frequency conversion, modulation, demodulation, adjacent channel processing, level adjustment and control, mixing, and so on.

The ADC is a device that converts a continuously changing analog signal into a discrete digital signal. By means of which the analog signal can be converted into a digital form that is easier to store, process and transmit.

The MCU can perform algorithm processing on the received digital signals and send the processed digital signals to a processor of the mobile terminal.

In addition, the optical processing chip may further include an integration time register, an amplification gain register, and the like.

Exemplarily, referring to fig. 7 in combination, a schematic diagram of an ambient light parameter acquisition process is exemplarily shown. The optical receiver 53 may convert an optical signal of ambient light into a current analog signal after receiving the optical signal; then the current analog signal is converted into a voltage analog signal through the AFE541 by a filter through a resistor, the voltage analog signal is amplified by an operational amplifier, and the amplified voltage analog signal also needs to pass through the filter to filter the amplified noise signal in the amplifier, so that the signal-to-noise ratio is improved. Then, the processed voltage analog signal obtained after the operational amplifier and the filtering process can be collected by the ADC542, so that the voltage analog signal is converted into a voltage digital signal, and is easier to store and process. The converted voltage digital signal may be subjected to algorithmic processing in the MCU543 to generate ambient light parameters. After the ambient light parameters are generated, backlight adjustment can be performed according to the ambient light parameters, so that display contents of the terminal can be displayed clearly, and the comfort degree of human eyes of a user is kept.

To sum up, the terminal provided by the embodiment of the present disclosure includes a first display screen assembly disposed on the front panel and a second display screen assembly disposed on the back panel, where the first display screen assembly corresponds to the first optical sensor and the second display screen assembly corresponds to the second optical sensor. Compared with the prior art, when a user uses the display screen on the terminal backboard, the terminal provided by the disclosure can collect the ambient light parameters through the optical sensor corresponding to one of the display screens respectively according to the ambient light parameters collected by the optical sensor arranged on the front panel, and can more accurately perform backlight adjustment on each display screen.

Optionally, the determining, by the state information, a target display screen interacted by the user according to the state information, where the state information includes acceleration data acquired by an acceleration sensor of the terminal, includes: if the acceleration data in the gravity direction belongs to a first value range, determining that a target display screen interacted by the user is a first display screen; and if the acceleration data in the gravity direction belongs to a second value range, determining that the target display screen interacted by the user is a second display screen.

The first value range may be less than 0, and the second value range may be greater than 0; in addition, when the first value range is greater than 0, the second area value range is less than 0, which is not limited in the embodiment of the present disclosure.

Optionally, if the acceleration data in the gravity direction is equal to 0, determining that the target display screen interacted by the user is a default display screen, where the default display screen is the first display screen.

In step 803, if the target display screen is the first display screen, a first ambient light parameter is collected by the first optical sensor.

When the target display screen is determined to be the first display screen, the first optical sensor may be powered on, and after the initialization configuration, a first ambient light parameter is collected through the first optical sensor, where the first ambient light parameter may be an ambient light intensity, an ambient light color temperature, an ambient light ultraviolet intensity, or the like.
