Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 5, a photosensitive element includes:
the mobile terminal comprises a photosensitive device 1, wherein the photosensitive device 1 is arranged in the mobile terminal, and the photosensitive device 1 is electrically connected with a circuit board 2 of the mobile terminal;
the light guide device 3, the light incident surface 31 of the light guide device 3 is disposed on the outer surface of the mobile terminal, that is, the light incident surface 31 of the light guide device 3 is exposed out of the mobile terminal, and the light emitting surface 32 of the light guide device 3 is located inside the mobile terminal and faces the light incident surface 11 of the light sensor 1.
The working principle of the embodiment of the invention is as follows:
first, ambient light is incident into the light guide device 3 through the light incident surface 31 of the light guide device 3.
Next, the light is transmitted in the light guide 3 and exits from the light exit surface 32 of the light guide 3.
Then, the light emitted from the light emitting surface 32 of the light guide device 3 continues to enter the photosensor 1 through the light incident surface 11 of the photosensor 1, so that the purpose that the photosensor 1 receives the ambient light is achieved.
And finally, the photosensitive device 1 converts the received optical signal into an electric signal and sends the electric signal to the circuit board 2 of the mobile terminal, so that the circuit board 2 controls or adjusts the brightness of the display screen of the mobile terminal according to the intensity of the ambient light.
The light incident surface 11 of the photosensor 1 may or may not contact the light emitting surface 32 of the light guide device 3, as long as the light incident path is complete, which is not limited in the embodiment of the present invention.
The specific position and the specific mode of the photosensor 1 disposed inside the mobile terminal are not limited in the embodiments of the present invention, as long as the light entrance path is complete. For example, a rest 41 is disposed on the housing 4 of the mobile terminal, and the photosensor 1 is fixed on the rest 41 by means of a back adhesive; or, a base 5 is arranged in the mobile terminal, and the photosensitive device 1 is fixed on the base 5 in a gum manner; and so on.
The specific embodiment of electrically connecting the photosensor 1 and the circuit board 2 of the mobile terminal is not limited in the embodiment of the present invention, as long as the light incident path is complete. For example, the photosensor device 1 is fixed to an FPC6(Flexible Printed Circuit) by an SMT (Surface Mount Technology) process, and the FPC6 is attached to the Circuit board 2 by the connector 7; or, the photosensitive device 1 is directly fixed on the circuit board 2 through an SMT process; and so on.
The light guide device 3 may be made of any light guide material with light transmittance satisfying the working performance of the photosensor 1. For example, a light guide material such as glass, organic glass, or PPSU (Polyphenylene sulfone resins).
The light guide device 3 may be disposed on the housing 4 of the mobile terminal, for example, the light guide device 3 may be fixed on the housing 4 of the mobile terminal by a back adhesive, and the light guide device 3 may also be injection molded with the housing 4 of the mobile terminal (for example, ordinary in-mold injection molding or nano injection molding, etc.). The appearance of the light guide device 3 can be adjusted according to the requirements.
In the embodiment of the invention, by arranging the light guide device, the ambient light can be conducted to the photosensitive device through the light guide device. Because the light guide device is arranged, the photosensitive device can be arranged in the mobile terminal, and thus the arrangement of the photosensitive device does not need to occupy the area where the display module of the mobile terminal is located. Therefore, the embodiment of the invention solves the problem of limiting the increase of the screen occupation ratio of the mobile terminal due to the fact that the photosensitive device is arranged in the area where the display module of the mobile terminal is located.
The invention is not only suitable for the light guide design of the photosensitive device, but also suitable for other devices with similar light guide requirements.
Optionally, the light emitting surface 32 of the light guide device 3 is parallel to the light incident surface 11 of the photosensor 1.
In this embodiment, the light-emitting surface 32 of the light guide device 3 is parallel to the light-entering surface 11 of the photosensor 1, so that more light rays emitted from the light-emitting surface 32 of the light guide device 3 can be emitted to the light-entering surface 11 of the photosensor 1, and the intensity of the ambient light received by the photosensor 1 can be increased, thereby increasing the sensitivity of the photosensor 1 to the light rays.
Optionally, a gap is provided between the light guide device 3 and the photosensor device 1.
Considering that the photosensitive device 1 is a fragile element, a gap is reserved between the light guide device 3 and the photosensitive device 1, so that damage possibly caused when the light guide device 3 is in direct contact with the photosensitive device 1 is avoided, and the service life of the photosensitive device 1 is prolonged. The width of the gap may be in a range of 0.2 mm to 0.4 mm, and specifically, may be preferably 0.3 mm, which not only can ensure the safety space between the light guide device 3 and the light sensor 1, but also does not occupy too much internal space of the mobile terminal due to the too wide gap.
Optionally, the light transmittance of the light guide device 3 is greater than or equal to 10% and less than 100%.
In this embodiment, on the one hand, when the light transmittance of the light guide device 3 is greater than or equal to 10%, the light rays guided from the light guide device 3 into the photosensor 1 can satisfy the normal operation performance of the photosensor 1. Preferably, the light guide device 3 has a light transmittance of 12% or more and less than 100%.
On the other hand, the light transmittance of the light guide device 3 is less than 100%, which means that the light guide device 3 is a semitransparent light guide device (or the light incident surface 31 of the light guide device 3 is a fog surface). Like this, can't see the inside device of mobile terminal from the mobile terminal outside, can hide or shelter from the inside device of mobile terminal better to can promote mobile terminal's whole outward appearance and experience. In addition, the color of the light guide 3 can be set to match the color of the housing 4 of the mobile terminal according to the requirement of the overall appearance of the mobile terminal.
Further, the light incident surface 31 of the light guide device 3 and the surface of the housing 4 of the mobile terminal form a continuous smooth surface.

Since the first light incident surface 311 of the light guide device 3 is parallel to the plane where the touch panel 8 of the mobile terminal is located, the first light incident surface 311 of the light guide device 3 can receive incident light perpendicular to the touch panel 8; the second light incident surface 312 of the light guide device 3 can receive oblique incident light. Therefore, the light guide device 3 of the embodiment of the invention is more diversified in light incidence mode, so that the light guide device 3 can receive incident light rays with more angles and a wider range, and the light ray conduction performance of the light guide device 3 is improved.
Further, the photosensor 1 is disposed in an inclined manner inside the mobile terminal, for example, a tilt table 41 is disposed on the housing 4 of the mobile terminal, and the photosensor 1 is disposed on the tilt table 41. An included angle alpha formed by a plane where a touch panel 8 of the mobile terminal is located and the light incident surface 11 of the photosensor 1 is smaller than or equal to 45 degrees.
