<FIG> is a schematic structural diagram of an electronic device <NUM> shown according to an example. <FIG> is a schematic structural diagram of a light guiding piece <NUM> shown according to an example. <FIG> is an exploded view chart of the light guiding piece <NUM> in <FIG>. As shown in <FIG>, the electronic device <NUM> may include a housing <NUM> or shell, a display panel <NUM>, an ambient light sensor <NUM>, an infrared transmitter <NUM> and a light guiding piece <NUM>. The housing <NUM> may include a battery cover, a middle frame or a front shell. The display panel <NUM> may be connected with the front shell of the electronic device <NUM>, so as to display an image through the display panel <NUM> which may include a light-transmitting area <NUM>. The ambient light sensor <NUM>, the infrared transmitter <NUM> and the light guiding piece <NUM> may all be arranged in the electronic device <NUM>. For example, the ambient light sensor <NUM> and the infrared transmitter <NUM> may be connected to the housing <NUM> or other components in the electronic device <NUM>, and/or the ambient light sensor <NUM> and/or the infrared transmitter <NUM> may also be connected and fixed to the light guiding piece <NUM>. The external ambient light intensity of the electronic device <NUM> can be sensed through the ambient light sensor <NUM>, and then the electronic device <NUM> can adjust the brightness of the display panel <NUM> according to the ambient light intensity. The infrared transmitter <NUM> can emit infrared light towards the outside of the electronic device <NUM>, for example, a remote control or ranging function of the electronic device <NUM> can be achieved through the infrared light.

The light guiding piece <NUM> may include a light incident end <NUM> and a light emitting end <NUM>. The light incident end <NUM> is configured facing the light-transmitting area <NUM> of the display panel <NUM>, and the light emitting end <NUM> may be configured facing the ambient light sensor <NUM> and the infrared transmitter <NUM>, so that the external ambient light can be transmitted to the ambient light sensor through the light-transmitting area <NUM> and the light guiding piece <NUM>, while the infrared light emitted by the infrared transmitter <NUM> can also be emitted to the outside of the electronic device <NUM> through the light guiding piece <NUM> and the light-transmitting area <NUM>. Based on this, the ambient light and the infrared light can be transmitted simultaneously through the light guiding piece <NUM>. The ambient light sensor <NUM> and the infrared transmitter <NUM> can share the same light guiding piece <NUM>, which is conducive to increasing the quantity of the ambient light sensors <NUM> for the electronic device <NUM>, so as to improve the detection accuracy of the ambient light intensity, and further save the internal space of the electronic device. The above description takes the display panel <NUM> including the light-transmitting area <NUM> as an example. In fact, in other examples, the light-transmitting area may also be formed on the housing <NUM>, for example, an opening may be processed and formed in the housing <NUM> as the light-transmitting area, or an opening may be formed in a top of the housing <NUM> as the light-transmitting area. Compared with the solution of forming the light-transmitting area <NUM> on the display panel <NUM>, the display area of the display panel <NUM> does not need to be occupied in the solution where the light-transmitting area is formed on the housing <NUM>, and the light-transmitting area may not be arranged on a display side of the electronic device <NUM>, which can improve the visual effect. And when the light-transmitting area is located at the top of the electronic device <NUM>, it is conducive to increasing the light field range of the ambient light sensor <NUM> and greatly improving the detection accuracy.

In the example, the ambient light sensor <NUM> and the infrared transmitter <NUM> can guide light through different light guiding channels of the light guiding piece <NUM> respectively. In one example, as still shown in <FIG> and <FIG>, the light guiding piece <NUM> may include a first light guiding column <NUM>, a second light guiding column <NUM> and a light-shielding body <NUM>. The light-shielding body <NUM> may include a first mounting hole <NUM> and a second mounting hole <NUM>. The first light guiding column <NUM> may be arranged in the first mounting hole <NUM>, in which a first end of the first light guiding column <NUM> is configured facing the light-transmitting area <NUM>, and a second end of the first light guiding column <NUM> is configured facing the ambient light sensor <NUM>. The second light guiding column <NUM> may be arranged in the second mounting hole <NUM>, in which a first end of the second light guiding column <NUM> may be configured facing the light-transmitting area <NUM>, and a second end of the second light guiding column <NUM> may be configured facing the infrared transmitter <NUM>. Based on this, an infrared light path of the infrared transmitter <NUM> and an ambient light path of the ambient light sensor <NUM> can be physically isolated to avoid light crosstalk and affecting the detection accuracy of the ambient light sensor <NUM>. The light-shielding body <NUM> may include a non-light-transmitting polycarbonate light-shielding body, and external light is prevented from being emitted through sides of the first light guiding column <NUM> and the second light guiding column <NUM>. The first light guiding column <NUM> may include a light-transmitting acrylic light guiding column, and the second light guiding column <NUM> may include a light-transmitting acrylic light guiding column.

Further, the light guiding piece <NUM> may further include a light guiding seat body <NUM>, which is respectively connected with the first light guiding column <NUM>, the second light guiding column <NUM> and the light-shielding body <NUM>. The light guiding seat body <NUM> may further be connected with the housing <NUM> of the electronic device <NUM>, so as to fix the light guiding piece <NUM> into the electronic device <NUM> and avoid moving. The ambient light sensor <NUM> and the infrared transmitter <NUM> may be connected to an end, facing away from the first light guiding column <NUM> and the second light guiding column <NUM>, of the light guiding seat body <NUM>, so as to achieve the purpose of light guidance through the first light guiding column <NUM> and the second light guiding column <NUM>. The first light guiding column <NUM>, the second light guiding column <NUM> and the light guiding seat body <NUM> may be integrally formed, or in other cases, the first light guiding column <NUM>, the second light guiding column <NUM> and the light guiding seat body <NUM> may also be separately formed, and their relative position relationship may be fixed by bonding or other means. The light guiding seat body <NUM> and the light-shielding body <NUM> may be fixedly connected by bonding.

In the example, as shown in <FIG>, the light guiding seat body <NUM> may include a mounting groove <NUM> recessed from a side facing away from the light-shielding body <NUM>, and the ambient light sensor <NUM> and the infrared transmitter <NUM> may both be located in the mounting groove <NUM>, so that light can be converged by the surrounding effect of the mounting groove <NUM>. Thus, compared with the solution that the light guiding seat body <NUM> is spaced from the ambient light sensor <NUM> and the infrared transmitter <NUM>, the loss of the light can be reduced, and it is conducive to improving the detection accuracy of the ambient light sensor <NUM> and the remote control effectiveness of the infrared transmitter <NUM>.

In another example, as shown in <FIG>, the light guiding piece <NUM> may include a shared part <NUM>, a first light guiding sub-part <NUM> and a second light guiding sub-part <NUM>. The first light guiding sub-part <NUM> and the second light guiding sub-part <NUM> are connected to a first end of the shared part <NUM>, from which the first light guiding sub-part <NUM> and the second light guiding sub-part <NUM> extend in different directions respectively. An end, away from the shared part <NUM>, of the first light guiding sub-part <NUM> is configured facing the ambient light sensor <NUM>, and an end, away from the shared part <NUM>, of the second light guiding sub-part <NUM> is configured facing the infrared transmitter <NUM>, so that the ambient light can be transmitted through the first light guiding sub-part <NUM>, and the infrared light can be transmitted through the second light guiding sub-part <NUM>. An end, away from the first light guiding sub-part <NUM> and the second light guiding sub-part <NUM>, of the shared part <NUM> is configured facing the light-transmitting area <NUM>. In order to achieve the physical isolation of the ambient light path and the infrared light path on the shared part <NUM>, the shared part <NUM> may include a light-shielding boundary layer <NUM> including a first edge and two opposing second edge. The first edge is located between the first light guiding sub-part <NUM> and the second light guiding sub-part <NUM>, and the second edge extends in the height direction of the shared part <NUM> until to be at least flush with a surface of the shared part <NUM>. Based on this, the shared part <NUM> may be divided into two parts through the light-shielding boundary layer <NUM>, so that one part may be connected with the first light guiding sub-part <NUM>, and the other part may be connected with the second light guiding sub-part <NUM>, so as to achieve the light path isolation of the ambient light and the infrared light on the shared part <NUM>. The shared part <NUM> includes a polycarbonate light-transmitting shared part. One part, connected with the first light guiding sub-part <NUM> and located on a side of the light-shielding boundary layer <NUM>, of the polycarbonate light-transmitting shared part may transmit the ambient light; and one part, connected with the second light guiding sub-part <NUM> and located on a side of the light-shielding boundary layer <NUM>, of the polycarbonate light-transmitting shared part may transmit the infrared light. The first light guiding sub-part <NUM> may include a visible light guiding sub-part, and the second light guiding sub-part <NUM> may include an infrared light guiding sub-part.

Further, as still shown in <FIG>, a sectional area of the first light guiding sub-part <NUM> may decrease progressively from an end close to the shared part <NUM> to an end away from the shared part <NUM>. In other words, the closer the end of the first light guiding sub-part <NUM> is to the ambient light sensor <NUM>, the smaller the sectional area is, so as to facilitate the convergence of the ambient light irradiated from the outside. The second light guiding sub-part <NUM> may include an arc-shaped surface <NUM>, which is located on a side, away from the first light guiding sub-part <NUM>, of the second light guiding sub-part <NUM>. An emission direction of the infrared transmitter <NUM> points to the arc-shaped surface <NUM> from an end, away from the shared part <NUM>, of the second light guiding sub-part <NUM>, so that the infrared transmitter <NUM> may emit the infrared light towards the arc-shaped surface <NUM> of the second light guiding sub-part <NUM>. Since the arc-shaped surface <NUM> can increase the area of a reflecting surface, more infrared light can be reflected, which is conducive to reducing the loss of the infrared light.

In other cases, the ambient light sensor <NUM> and the infrared transmitter <NUM> may also share the same light guiding channel of the light guiding piece <NUM>, so as to simplify a structure of the light guiding piece <NUM>. For example, as shown in <FIG>, the light guiding piece <NUM> may be an integrated light guiding column which may transmit infrared light and visible light. The integrated light guiding column includes a first lens part <NUM> and a second lens part <NUM> which are arranged on the light emitting end <NUM>. The first lens part <NUM> faces the ambient light sensor <NUM>, and the second lens part <NUM> faces the infrared transmitter <NUM>. Based on this, the loss of light can be reduced by using the condensing effect of the first lens part <NUM> and the second lens part <NUM>. In the example, when the ambient light sensor <NUM> and the infrared transmitter <NUM> are located at the same height, as shown in <FIG>, an end, facing the ambient light sensor <NUM> and the infrared transmitter <NUM>, of the integrated light guiding column may be basically at the same height. When an end, facing the light guiding piece <NUM>, of the ambient light sensor <NUM> and an end, facing the light guiding piece <NUM>, of the infrared transmitter <NUM> are located at different heights, as shown in <FIG>, in a height direction of the integrated light guiding column, the height difference between the first lens part <NUM> and the second lens part <NUM> may be greater than zero, so as to adapt to the ambient light sensor <NUM> and the infrared transmitter <NUM>, which is conducive to the layout of other components in the electronic device <NUM>.

After considering the specification and practicing the disclosure disclosed herein, those skilled in the art will easily think of other embodiments of the disclosure. The disclosure is intended to cover any variations, uses, or adaptive changes of the disclosure. These variations, uses, or adaptive changes follow the general principles of the disclosure and include common knowledge or conventional technical means in the technical field that are not disclosed in the disclosure.
