For example, a currently popular mobile phone (i.e., a portable electronic device) with an ultra-narrow bezel display screen is popular with consumers by further enlarging the effective display area to achieve higher-level visual experience and aesthetic design.
However, the currently declared full-screen mobile phone in the industry is only a mobile phone with an ultra-high screen ratio, and does not have a screen ratio of 100%, and the main reason is that in the front of the smart phone, besides a display screen, various electronic components need to be provided.

However, referring to fig. 10, as shown in fig. 10, since the distance sensor 3 is usually disposed on the front surface of the mobile phone 4 (i.e. the portable electronic device), the screen occupation ratio of the display screen 41 is inevitably affected.

Detailed Description
The present invention is described in terms of specific embodiments, which are illustrated in the accompanying drawings, and other advantages and effects of the invention will be apparent to those skilled in the art from the disclosure herein. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways. Various modifications and alterations may be made in the details of this description without departing from the spirit of the invention, from various aspects and applications. In particular, the relative proportions and positions of the various elements in the drawings are exemplary only, and are not intended to represent the actual conditions in which the present invention is practiced.
The optical signal transceiver of the portable electronic equipment avoids the display screen from transmitting and receiving optical signals through the body frame, so as to achieve the purpose of improving the display screen occupation ratio and meet higher-order visual experience and design aesthetic feeling, thus simplifying the manufacturing process of the display screen panel and being beneficial to reducing the manufacturing cost of the display screen.
For the description of the embodiments of the present disclosure, please refer to fig. 1 to 9 together.
As shown in fig. 1 to 9, the portable electronic device 1 of the present invention is, for example, a smart phone capable of receiving and emitting light signals, wherein the portable electronic device 1 includes: an apparatus body 11, a light guide 12 and an optical transceiver 13. The device body 11 has a display screen 111 and a body frame 112. The body frame 112 extends along the outer edge of the display screen 111 to provide positioning and protection for the display screen 111, and the body frame 112 has an optical via structure 1121.
The light guide 12 can be used to conduct light signals. In the present invention, the main body of the light guiding element 12 is embedded in the frame 112 of the main body, and has a first refraction surface 121, a second refraction surface 122, a total reflection surface 123, an accommodating space 124 and an optical column 125, respectively. The first refraction surface 121 is exposed from the body frame 112 and is away from the display screen 111, so as to prevent the first refraction surface 121 from reducing the screen occupation ratio of the display screen 111. The receiving space 124 is used for receiving the optical transceiver 13, and the second refraction surface 122 is disposed on the wall surface of the light guide element 12 forming the receiving space 124, so as to face the optical transceiver 13. Preferably, the first refraction surface 121, the second refraction surface 122 and the total reflection surface 123 are respectively formed on three end side surfaces of the optical cylinder 125, so as to reduce the manufacturing difficulty of the light guide assembly 12.
The optical signal transceiver 13 is, for example, a distance sensor, and the main body thereof is embedded in the main body frame 112 to transmit the first optical signal R1 to the object 2, for example, a user, or receive the second optical signal R2 from the object 2. Preferably, the second optical signal R2 is generated by reflecting the first optical signal R1 that travels to the object 2, so that the state of the object 2, such as distance, can be determined by the difference between the first optical signal R1 and the second optical signal R2.
Specifically, the first optical signal R1 travels from the optical signal transceiver 13 toward the second refraction surface 122, then enters the second refraction surface 122, and is refracted by the second refraction surface 122 to cause the first optical signal R1 to travel toward the total reflection surface 123. As shown in fig. 6 and fig. 8, since the medium of the path of the first optical signal R1 before and after entering the second refraction surface 122 changes, the incident angle θ 11 of the first optical signal R1 on the second refraction surface 122 is substantially greater than the refraction angle θ 12, so that the first optical signal R1 can travel toward the total reflection surface 123 along the predetermined direction.
Then, the first optical signal R1 enters the total reflection surface 123, and through total reflection of the total reflection surface 123, the first optical signal R1 travels toward the first refraction surface 121, and then enters the first refraction surface 121, and through refraction of the first refraction surface 121, the first optical signal R1 travels toward the object 2, and the first refraction surface 121 is exposed through the optical via structure 1121, so that the first optical signal R1 can leave the apparatus body 11 and travel toward the object 2, so that the optical signal transceiver 13 completes sending the first optical signal R1 to the object 2. As shown in fig. 6 and 8, since the medium of the first optical signal R1 before and after entering the first refraction surface 121 changes, the incident angle θ 13 of the first optical signal R1 on the first refraction surface 121 is substantially smaller than the refraction angle θ 14, so that the first optical signal R1 can travel toward the object 2 along a predetermined direction.
As shown in fig. 6 and fig. 8, the incident angle θ 1R of the first optical signal R1 on the total reflection surface 123 is substantially equal to the sum of the angle α of intersection between the second refraction surface 122 and the total reflection surface 123 and the angle θ 12 of refraction of the first optical signal R1 on the second refraction surface 122. The incident angle θ 13 of the first optical signal R1 on the first refractive surface 121 is substantially equal to the difference between the angle γ of the first refractive surface 121 intersecting the total reflective surface 123 and the incident angle θ 1R of the first optical signal R1 on the total reflective surface 123. Therefore, the traveling direction of the first optical signal R1 is related to the tilt angles of the first refractive surface 121, the second refractive surface 122 and the total reflective surface 123, so that the first optical signal R1 can be ensured to travel toward the object 2 and avoid the display screen 111 along the predetermined direction only by adjusting the tilt angles of the first refractive surface 121, the second refractive surface 122 and the total reflective surface 123.
In addition, the second optical signal R2 travels from the object 2 toward the first refractive surface 121, then enters the first refractive surface 121, and is refracted by the first refractive surface 121, so that the second optical signal R2 travels toward the total reflection surface 123. As shown in fig. 7 and fig. 9, since the medium of the second optical signal R2 before and after entering the first refraction surface 121 changes, the incident angle θ 24 of the second optical signal R2 on the first refraction surface 121 is substantially larger than the refraction angle θ 23, so that the second optical signal R2 can travel toward the total reflection surface 123 along a predetermined direction. It should be noted that the first refraction surface 121 is exposed through the optical via structure 1121, so that the second optical signal R2 can enter the apparatus body 11 and travel toward the optical signal transceiver 13, so that the optical signal transceiver 13 can receive the second optical signal R2 from the object 2.
Then, the second optical signal R2 enters the total reflection surface 123, and the total reflection of the total reflection surface 123 makes the second optical signal R2 go toward the second refraction surface 122, and then enters the second refraction surface 122, and the refraction of the second refraction surface 122 makes the second optical signal R2 go toward the optical signal transceiver 13, so that the optical signal transceiver 13 completes receiving the second optical signal R2 from the object 2. As shown in fig. 7 and fig. 9, since the medium of the path of the second optical signal R2 before and after entering the first refraction surface 121 changes, the incident angle θ 22 of the second optical signal R2 on the second refraction surface 122 is substantially smaller than the refraction angle θ 21, so that the second optical signal R2 can travel toward the optical signal transceiver 13 along the predetermined direction.
As shown in fig. 7 and fig. 9, the incident angle θ 2R of the second optical signal R2 on the total reflection surface 123 is substantially equal to the sum of the angle α of the second refraction surface 122 intersecting the total reflection surface 123 and the incident angle θ 22 of the second optical signal R2 on the second refraction surface 122. The refraction angle θ 23 of the second optical signal R2 on the first refraction surface 121 is substantially equal to the difference between the angle γ of the first refraction surface 121 intersecting the total reflection surface 123 and the incident angle θ 2R of the second optical signal R2 on the total reflection surface 123. The traveling direction of the second optical signal R2 is related to the tilt angles of the first refractive surface 121, the second refractive surface 122 and the total reflective surface 123, so that the second optical signal R2 can be ensured to travel toward the optical signal transceiver 13 along the predetermined direction and avoid the display screen 111 only by adjusting the tilt angles of the first refractive surface 121, the second refractive surface 122 and the total reflective surface 123.
In summary, the portable electronic device of the present invention can receive the light signal, and the light guide assembly provides the light signal with two stages of refraction and one stage of total reflection, so that the light signal can avoid the display screen from entering and exiting the device body through the body frame.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be as set forth in the claims of the present invention.
