The optical device 2 is located at the rear cover of the electronic apparatus for receiving or transmitting an optical signal, and in order to protect the optical device 2, a transparent glass cover plate 5 is usually provided at the outer side of the optical device 2, and light can be allowed to penetrate the glass cover plate 5. As shown in fig. 1, in the related art, an optical device module includes a circuit board 1, an optical device 2, and a glass cover plate 5. The optical device 2 is fixed on the circuit board 1 and is electrically connected with the circuit board 1, light rays in the environment transmit optical signals to the optical device 2 through the glass cover plate 5, and the optical device 2 converts the perceived optical signals into electric signals and transmits the electric signals to the circuit board 1. Alternatively, the optical device 2 emits an optical signal to the outside through the glass cover 5. However, the optical device 2 in the case of the electronic apparatus can be seen by the user through the glass cover plate 5, making the electronic apparatus aesthetically unattractive.

In the related art, as shown in fig. 1, in order to conceal the optical device 2, a semi-transparent black light-shielding ink 6 is generally coated on the inner side of a glass cover plate 5, so that the optical device 2 inside the electronic apparatus is not easily seen by a user. However, the light-shielding ink 6 has a low transmittance to visible light, so that the light signal received by the optical device 2 cannot accurately reflect the illumination intensity in the environment.

In view of the above technical problems, the embodiments of the present disclosure provide an optical device module, as shown in fig. 2, which includes a circuit board 1, an optical device 2, and a one-way see-through cover plate 3. The optical device 2 is fixed to the circuit board 1 and is electrically connected to the circuit board 1. The one-way see-through cover plate 3 is opposite to the optical device 2, wherein the one-way see-through cover plate 3 is used for transmitting light of a side with higher brightness to a side with lower brightness and blocking light of a side with lower brightness from being transmitted to a side with higher brightness.

The circuit board 1 may be a printed circuit board.

When the unidirectional perspective cover plate 3 is used, the illumination intensities of the two sides of the unidirectional perspective cover plate 3 should be different, so that a user cannot see the side with darker illumination intensity on the side with higher illumination intensity, namely, the unidirectional perspective cover plate 3 can serve as a mirror surface when the user is on the side with higher illumination intensity.

According to the technical scheme provided by the embodiment of the disclosure, when the optical device 2 does not emit an optical signal, the brightness of the outer side of the unidirectional perspective cover plate 3 is higher, so that external light can penetrate the unidirectional perspective cover plate 3 and irradiate the optical device 2, and the light of the inner side of the unidirectional perspective cover plate 3 is blocked from being transmitted to the outside, so that the optical device 2 is hidden. When the optical device 2 emits the optical signal, the brightness of the inner side of the unidirectional perspective cover plate 3 is higher, so that the optical signal emitted by the optical device 2 can penetrate the unidirectional perspective cover plate 3 and irradiate to the outside, and meanwhile, the user cannot directly view the optical device module when the optical device 2 emits the optical signal, so that the user cannot see the optical device 2.

In some examples, as shown in fig. 2, the one-way see-through cover plate 3 includes a cover plate body 31 and a one-way see-through film 32, the one-way see-through film 32 being attached to a surface of the cover plate body 31, the one-way see-through film 32 being opposite to the light device 2. Among other things, the unidirectional see-through film 32 may also be referred to as a unidirectional film, a mirror film, or the like.

In some examples, as shown in fig. 2, the one-way see-through film 32 is attached to the inside of the cover body 31, i.e., the side of the one-way see-through film 32 that is close to the light device 2. Thus, the cover plate body 31 can protect the unidirectional perspective film 32, so that the unidirectional perspective film 32 is not easy to damage.

In some examples, the one-way see-through film 32 is a silver film plated on the surface of the cover plate body 31, and the thickness of the silver film is smaller, so that the thickness of the one-way see-through cover plate 3 is not affected, and the thickness of the one-way see-through cover plate 3 is smaller.

Of course, in other examples, the one-way see-through film 32 may also be an aluminum film or the like.

In some examples, as shown in fig. 2, the light device 2 includes a light sensing element 21 and a flash 22, and the light sensing element 21 and the flash 22 are each fixed to the circuit board 1 and electrically connected to the circuit board 1. When the flash 22 is not operated, the brightness of the outside of the one-way see-through cover plate 3 is greater than the brightness of the inside of the one-way see-through cover plate 3, and the light sensing element 21 and the flash 22 are hidden by the one-way see-through cover plate 3. The outside of the one-way see-through cover plate 3 is a mirror surface at this time, so that the user cannot see the light sensing element 21 and the flash lamp 22. At the same time, the light sensing element 21 converts the sensed light signal into an electrical signal and transmits the electrical signal to the circuit board 1, so that the circuit board 1 adjusts the screen brightness of the electronic device according to the external illumination intensity.

When the flash lamp 22 works, the brightness of the inner side of the one-way perspective cover plate 3 is larger than the brightness of the outer side of the one-way perspective cover plate 3, and the light emitted by the flash lamp 22 is emitted from the one-way perspective cover plate 3, and at the moment, one side of the one-way perspective cover plate 3, which is close to the flash lamp 22, is a mirror surface. Since the light emitted from the flash lamp 22 is brighter, the user cannot directly view the light device module, and thus the user cannot see the flash lamp 22 and the light sensing element 21 inside the light device module.

In the related art, as shown in fig. 1, since the light transmittance of the light shielding ink 6 is low, the brightness of the flash 22 is affected, and therefore the light shielding ink 6 is applied only to the position where the glass cover 5 faces the light sensing element 21. Since the light shielding ink 6 is not applied to the position of the glass cover 5 opposite to the flash 22, the light transmittance of the region of the glass cover 5 opposite to the light sensing element 21 is made different from the region of the glass cover 5 opposite to the flash 22. In this way, the light intensity of the external light after penetrating through the two areas is also different, so that the light incident from the position where the glass cover plate 5 is opposite to the flash lamp 22 will interfere with the light sensing element 21, so that the light distribution received by the light sensing element 21 is uneven, and further, the circuit board 1 is difficult to accurately adjust the screen brightness of the electronic device.

As shown in fig. 3, in the related art, in order to avoid interference of the light incident from the position of the glass cover 5 opposite to the flash lamp 22 with the light sensing element 21, the baffle 7 is disposed between the flash lamp 22 and the light sensing element 21, but the assembly process is complicated due to more parts inside the light device module.

The light transmittance of the unidirectional perspective cover plate 3 in the embodiment of the disclosure is higher and can reach 95%, so that even if the unidirectional perspective cover plate 3 does not have a unidirectional perspective film at the position opposite to the flash lamp 22, the light incident from the position opposite to the flash lamp 22 of the unidirectional perspective cover plate 3 is difficult to interfere with the photosensitive element 21, and therefore, the baffle 7 is not required to be arranged, so that the number of parts in the optical device module is less, and the assembly process of the optical device module is simpler.

In some examples, as shown in fig. 2, the light device module further includes a light equalizing film 4, the light device 2 further includes a flash lens 23, the light equalizing film 4 is opposite to the light sensing element 21, and the flash lens 23 is opposite to the flash 22. The light equalizing film 4 is attached to the inner side of the unidirectional perspective cover plate 3, and the flash lens 23 and the light equalizing film 4 are arranged in parallel.

The light-equalizing film 4 may be also referred to as a diffusion film or a light-equalizing film, and the light-equalizing film 4 may uniformly diffuse the light after receiving the light transmitted through the one-way see-through cover plate 3, so that the light-sensing element 21 may uniformly receive the light signal. Wherein, the light-homogenizing film 4 can be white light-homogenizing ink. The light equalizing film 23 is attached to the inner side of the cover plate body 31, so that the cover plate body 31 can protect the light equalizing film 4, and the light equalizing film 4 is not easy to damage. The flash lens 23 serves to disperse light emitted from the flash 23 more uniformly.

In the related art, in order to hide the flash 22, the flash lens 23 is atomized, so that the flash lens 23 is semitransparent, but the light emitting effect of the flash 22 is also affected. In the embodiment of the disclosure, since the one-way perspective cover plate 3 already conceals the flash 22, the flash lens 23 does not need to be atomized, so that the flash lens 23 is fully transparent.

In some examples, the cover body 31 is a glass plate. The glass plate is coated with the unidirectional perspective film 32 and can be called unidirectional glass, the transmittance of the unidirectional glass can reach 95%, and the unidirectional glass has no large difference from common glass, and can not influence the light sensing element 21 to receive light signals or influence the flash lamp 22 to emit light signals.

The embodiment of the disclosure also provides an electronic device, as shown in fig. 4, where the electronic device includes the optical device module.

According to the technical scheme provided by the embodiment of the disclosure, as the unidirectional perspective cover plate 3 is arranged in the optical device module in the electronic equipment, the optical device 2 can be hidden in the unidirectional perspective cover plate 3, so that a user cannot see the optical device 2 through the unidirectional perspective cover plate 3, and the aesthetic degree of the electronic equipment is improved.

In some examples, as shown in fig. 4, the electronic device further includes a motherboard 100, a spring contact 200, and a bracket 300 that are sequentially arranged, where the motherboard 100 is electrically connected to the spring contact 200. The circuit board 1 is fixed to the bracket 300, and the circuit board 1 is electrically connected to the spring contact 200.

The main board 100 supplies power to the light sensing element 21 through the dome contacts 200 and the circuit board 1, so that the light sensing element 21 can convert a received light signal into an electrical signal. After the light sensing element 21 transmits the electrical signal to the circuit board 1, the circuit board 1 transmits the electrical signal to the motherboard 100, so that the motherboard 100 can adjust the screen brightness of the electronic device according to the brightness of the environment. When the ambient brightness is high, the main board 100 controls the screen brightness to increase, and when the ambient brightness is low, the main board 100 controls the screen brightness to decrease.

The main board 100 supplies power to the flash lamp 22 through the spring contact 200 and the circuit board 1, and can send an electric signal for controlling the flash lamp 22 to be turned on and off to the flash lamp 22, and the flash lamp 22 can convert the electric signal into an optical signal and emit light into the environment.

The foregoing description of the preferred embodiments of the present disclosure is provided for the purpose of illustration only, and is not intended to limit the disclosure to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, alternatives, and alternatives falling within the spirit and scope of the disclosure.
