[0041] [First embodiment]

Figure 1 The enlarged view of the II part of the electronic device of the present application embodiment. Figure 3 The cross-sectional view of the first embodiment taken along the cross-sectional line III-III in the first embodiment. Figure 1 The cross-sectional view of the first embodiment taken along the cross-sectional line III-III in the first embodiment.

[0043] Referring to Figures 1 to 3 , the present application embodiment provides an electronic device ED, which comprises a frame 1, a first display panel 2, a light emitting component 3, a transmitter 4, an optical component 5, a receiver 6, a circuit substrate 7 and a second display panel 8.

[0044] Firstly, the architecture of the electronic device ED is described, as shown in Figure 3 , from the perspective of the cross section of the electronic device ED, the frame 1 is a plate body with a certain thickness, the first side of the plate body has a flat surface S1, and the first display panel 2 is arranged on the first side of the frame 1 (as shown in Figure 3The frame 1 is further extended towards the edge of the electronic device ED and is lifted upwards to form a side wall portion 10 as a part of the housing of the electronic device ED and to support the first display panel 2 in this embodiment, but the present application is not limited thereto. The side wall portion 10 has a certain height H in a direction perpendicular to the flat surface S1 and surrounds the periphery of the electronic device ED, so that the first display panel 2 and the frame 1 jointly define a first accommodating space SP1, that is, the first accommodating space SP1 is jointly defined by the first display panel 2, the side wall portion 10 and the flat surface S1. The first accommodating space SP1 can be used to accommodate electronic components such as the light emitting assembly 3, the emitter 4 of the distance measuring module DM and the optical assembly 5. The light emitting assembly 3 can be a light emitting diode for example, but the present application is not limited thereto. The light emitting assembly 3 can be used to generate an illumination light beam LL, which can be used to provide illumination for the subject during shooting or as a flashlight.

[0045] On the other hand, the first display panel 2 is provided with a light transmission portion 21, so that the light emitted by the electronic components arranged in the first accommodating space SP1 can penetrate the first display panel 2. For example, the light emitting assembly 3, the emitter 4 and the optical assembly 5 arranged in the first accommodating space SP1 can correspond to the light transmission portion 21 in position, and more precisely, the optical assembly 5 overlaps the light emitting assembly 3 and the emitter 4 respectively in the normal direction DN of the flat surface S1.

[0046] Since the optical assembly 5 is arranged above the light emitting assembly 3 and the emitter 4, it can be used to adjust the optical properties of the light emitting assembly 3 and the emitter 4. In order to clearly show the internal structure of the optical assembly 5, the optical assembly 5 is shown in a perspective view in FIG. 2. Figure 2 is transparentized. As viewed from the top, the optical assembly 5 includes a top plate structure 52 and two strip structures 50. The strip structures 50 are arranged on both sides of the optical assembly 5 as support columns for supporting the top plate structure 52, so that the optical assembly 5 as a whole appears as a cover with an opening facing downwards. In addition, the top plate structure 52 of the optical assembly 5 can include a first portion 520 and a second portion 522.

[0047] As shown in FIG. 3, the first portion 520 of the top plate structure 52 of the optical assembly 5 is arranged above the light emitting assembly 3 and the emitter 4, and the second portion 522 of the top plate structure 52 is arranged above the light emitting assembly 3 and the emitter 4. Figure 2As shown, the first portion 520 is arranged corresponding to the light emitting component 3 and provides the light beam LL generated by the light emitting component 3 with first optical characteristics. In this embodiment, the first portion 520 is a first lens portion with first microstructures 5201 and can be formed by a lens or any light-transmissive material. The first microstructures 5201 can be light diffusion structures or Fresnel lens structures. Specifically, the first microstructures 5201 can be arranged in two fan-shaped areas FA and a circular area CA of the top flat structure 52, and the two fan-shaped areas FA are arranged around the circular area CA. The circular area CA can be, for example, centered at the center point C of the top flat structure 52 corresponding to the light emitting component 3. The first microstructures 5201 can include a plurality of protruding microstructures arranged in the two fan-shaped areas FA and the circular area CA, each of which is a strip-shaped body and protrudes from the surface of the top flat structure 52 facing the light emitting component 3 towards the direction of the light emitting component 3. Some of the protruding microstructures are arc-shaped, and some of the protruding microstructures are circular, and are arranged around the center of the circular area CA. However, the above-mentioned implementation of the first microstructures 5201 is only an example, and the present application is not limited thereto. In addition, the number of first microstructures 5201 can increase with the increase in the number of light emitting components 3, and the present application is not limited to one light emitting component 3.

[0048] Based on the above architecture, when the light beam generated by the light emitting component 3 penetrates the first portion 520, the first portion 520 can provide the light beam generated by the light emitting component 3 with first optical characteristics, for example, to make the light beam have a first field of view range FOV1, which in optional embodiments is in the range of 65 degrees to 85 degrees. The first portion 520 can make the light beam generate large-angle light or uniform light to improve the overall brightness of the subject when shooting with a lens or to improve the illumination range when used as a flashlight.

[0049] Please refer to Figure 2 As shown, the second portion 522 is arranged corresponding to the emitter 4 and provides the ranging light beam generated by the emitter 4 with second optical characteristics. The emitter 4 can be, for example, a vertical cavity surface emitting laser (VCSEL). When the ranging light beam of the emitter 4 penetrates the second portion 522, the ranging light beam has a second field of view range FOV2, which in optional embodiments is in the range of 25 degrees to 85 degrees. In some embodiments, since the ranging light beam itself already has a proper field of view, the field of view of the ranging light beam can be unchanged by changing the design of the second portion 522.

[0050] In the embodiment, the plurality of emitters 4 can be disposed around the light emitting assembly 3 in a predetermined manner. Taking the number of emitters 4 as two as an example, two emitters 4 can be symmetrically disposed on opposite sides of the light emitting assembly 3. Corresponding to this manner, the second portion 522 can be divided into sub-portions 522-1, 522-2, which are disposed in a similar manner to the first portion 520 corresponding to the two emitters 4. For example, when a plurality of protruding microstructures of the first microstructure 5201 are disposed around the circular region CA corresponding to the center point C of the light emitting assembly 3, the sub-portions 522-1, 522-2 can be disposed in a sector region around the circular region CA where the first microstructure 5201 is not disposed. Each of the sub-portions 522-1, 522-2 can be a second lens portion having a flat surface, but the utility model is not limited thereto.

[0051] Figure 3 To follow the Figure 1 schematic cross-sectional view of the first embodiment taken along the cross-sectional line III-III.

[0052] From the perspective of the front view of the cross section of the electronic device ED, the circuit substrate 7 is disposed in the first accommodating space SP1, and the outer shape of the circuit substrate 7 is a flat plate, which is located at the bottom of the first accommodating space SP1 and disposed on the flat surface S1 of the frame 1. The light emitting assembly 3, the emitter 4, and the optical assembly 5 are disposed on the circuit substrate 7. Among them, the optical assembly 5 is in the form of a cover with an opening facing downward, which together with the circuit substrate 7 forms a second accommodating space SP2, and the light emitting assembly 3 and the emitter 4 are covered therein.

[0053] In order to clearly show the internal structure of the electronic device ED, the first display panel 2 is Figure 1 transparentized. From the perspective of the top view, the distance measuring module DM of the electronic device ED in the embodiment further includes a receiver 6 and a processing circuit 9. The receiver 6 and the processing circuit 9 are disposed in the first accommodating space SP1, and the processing circuit 9 is electrically connected to the emitter 4 and the receiver 6. The receiver 6 is used to receive the reflected distance measuring light beams generated by the irradiation of the distance measuring light beams on the object X to be measured. The processing circuit 9 calculates the distance of the object X to be measured according to the emission time of each distance measuring light beam and the reception time of each reflected distance measuring light beam.

[0054] The electronic device ED of the embodiment can be a mobile device with a double screen, and the distance measuring module DM can be installed in the mobile device, Figure 1 The electronic device ED is a smart folding mobile phone. As shown in Figure 3 the frame 1 serves as the shell of the mobile device. From the perspective of the front view of the cross section of the electronic device ED, the first side of the frame 1 has a flat surface S1, and the first display panel 2 is disposed on the first side of the frame 1 (as shown in Figure 3(As shown above frame 1), and frame 1 has another flat surface S2 on its second side relative to the first side, and the second display panel 8 is disposed on the second side of frame 1. In this embodiment, the first display panel 2 and the lens module CAM of the moving device are disposed on the first side of frame 1, and the light-emitting component 3, the emitter 4, the optical component 5 and the circuit board 7 are disposed in the first accommodating space SP1 defined by the first display panel 2 and frame 1. In order to allow the light emitted by the light-emitting component 3 and the emitter 4 to penetrate the first display panel 2, the transmittance of the light-transmitting part 21 of the first display panel 2 corresponding to the optical component 5 is greater than the transmittance of the other light-transmitting part 22 in the first display panel 2. In addition, the strip-shaped structures 50 on both sides of the optical component 5 have light-blocking parts 54 on the two sides away from the top plate structure 52 to block light and reduce the influence of the light-transmitting part 21 on the surrounding pixels.

[0055] The ranging module DM in this embodiment can be, for example, a direct time-of-flight (DToF) ranging module. A DToF ranging module includes a vertical cavity surface-emitting laser (VCSEL), a single-photon avalanche diode (SPAD), and a time-to-digital converter (TDC), etc. The transmitter 4 is not limited to a vertical cavity surface-emitting laser; it can be, for example, an edge-emitting laser (EEL) or a fiber laser, or any device capable of generating a ranging beam, where the ranging beam is laser light. The receiver 6 is not limited to a single-photon avalanche diode; it can be, for example, a silicon photomultiplier (SiPM) or any device that can receive the reflected ranging beam generated when the ranging beam illuminates the object X.

[0056] In addition, such as Figure 1 As shown, the receiver 6 and transmitter 4 of the ranging module DM can be disposed on the same circuit board 7, and both are disposed within the first accommodating space SP1. Since the transmitter 4 is positioned corresponding to the high-transmittance light-transmitting part 21, the loss of the ranging beam can be reduced. Moreover, the reflected ranging beam received by the receiver 6 increases with the increase of the ranging beam. Furthermore, by moving the transmitter 4 to share the high-transmittance light-transmitting part 21 with the light-emitting component 3, the number of openings on the mobile phone screen can be reduced, improving the user experience.

[0057] The receiver 6 can be disposed on another circuit substrate 7, and is not limited to sharing the circuit substrate 7 with the transmitter 4 or the processing circuit 9, so as to improve flexibility of internal component layout of the electronic device. In the embodiment, the circuit substrate 7 can be, for example, a printed circuit board (PCB) or a flexible printed circuit (FPC), but the utility model is not limited thereto.

[0058] [Second embodiment]

[0059] Figure 4 A front view schematic diagram of an optical assembly of a second embodiment of the utility model.

[0060] In the embodiment, a plurality of transmitters 4 can be disposed around the light emitting assembly 3 in a predetermined manner. Taking the number of the transmitters 4 as four as an example, two transmitters 4 form a group, and two groups of transmitters 4 can be symmetrically disposed on opposite sides of the light emitting assembly 3. Corresponding to this manner, the second part 522 can be divided into subparts 522-1 and 522-2, and the two groups of transmitters 4 are correspondingly disposed in a similar manner with respect to the first part 520. For example, when a plurality of convex microstructures of the first microstructure 5201 are disposed around the circular region CA corresponding to the center point C of the light emitting assembly 3, the subparts 522-1 and 522-2 can be disposed in the fan-shaped region around the circular region CA which is not provided with the first microstructure 5201. Each of the subparts 522-1 and 522-2 can be a second lens part with a through hole, and the utility model is not limited thereto.

[0061] In the embodiment, one or more transmitters 4 can be disposed below each of the subparts 522-1 and 522-2. In the embodiment, the four transmitters 4 of the distance measuring module DM and the light emitting assembly 3 are both disposed on the flat surface S1 of the frame 1 when viewed from a top perspective, and two adjacent transmitters 4 can be collectively disposed corresponding to the through hole of one of the subparts 522-1 and 522-2. That is, two transmitters 4 are respectively disposed in each through hole, and the arrangement manner of the transmitters 4 can be straight parallel, horizontal parallel or surrounding the light emitting assembly 3, and the utility model is not limited thereto. In addition, the transmitters 4 can emit distance measuring beams from the same hole, or each transmitter 4 can emit distance measuring beams from different holes.

[0062] The utility model can adjust the distance measuring capability (for example, the farthest distance measuring distance) of the transmitter 4 by changing the optical structure of the optical assembly 5 corresponding to the transmitter 4. For example, when the through hole is used to replace the planar lens disposed at the subparts 522-1 and 522-2, the distance measuring capability can be improved. In addition, the size of the through hole is also related to the distance measuring capability, and in some embodiments, the distance measuring capability increases with the increase of the size of the through hole.

[0063] [Third embodiment]

[0064] Figure 5 for along Figure 1 a cross-sectional view of the third embodiment taken along

[0065] viewed from a front perspective of the cross-section of the electronic device ED, as Figure 5 shown, the optical assembly 5 is attached to the first display panel 2 and is at a predetermined distance from the circuit substrate 7. The first display panel 2 is provided with light-transmissive portions 21 so that light emitted by electronic components disposed in the first accommodation space SP1 can pass through the first display panel 2. For example, the light-emitting assembly 3, the emitter 4 and the optical assembly 5 disposed in the first accommodation space SP1 can correspond in position to the light-transmissive portions 21, more precisely, the optical assembly 5 overlaps each of the light-emitting assembly 3 and the emitter 4 in the direction of the normal DN of the planar surface S1. In addition, the optical assembly 5 is disposed above the light-emitting assembly 3 and the emitter 4, can be used to adjust the optical properties of the light-emitting assembly 3 and the emitter 4, and the light-emitting assembly 3 and the emitter 4 are at a predetermined distance from the optical assembly 5.

[0066] The top plate structure 52 of the optical assembly 5 is attached to the first display panel 2 and faces the surface of the first accommodation space SP1, and a surface of the optical assembly 5 opposite the circuit substrate 7 has a first portion 520 and a second portion 522.

[0067] As shown in Figure 2 , the first portion 520 is disposed corresponding to the light-emitting assembly 3 and provides the first optical assembly 5 with first optical properties for the illumination beam generated by the light-emitting assembly 3. In this embodiment, the first portion 520 is a first lens portion having first microstructures 5201, which can be formed by a lens or any light-transmissive material. The first microstructures 5201 can be light-diffusing structures or Fresnel lens structures. Specifically, the first microstructures 5201 can be disposed in two fan-shaped areas FA and a circular area CA of the top plate structure 52, and the two fan-shaped areas FA are disposed around the circular area CA. The circular area CA may, for example, be centered on the center point C of the top plate structure 52 corresponding to the light-emitting assembly 3. The first microstructures 5201 can include a plurality of protruding microstructures disposed at intervals in the two fan-shaped areas FA and the circular area CA, each protruding microstructure being a strip-shaped body and protruding from the surface of the top plate structure 52 facing the light-emitting assembly 3 in the direction of the light-emitting assembly 3. Some of the protruding microstructures are arc-shaped, and some of the protruding microstructures are circular, and are all disposed around the center of the circular area CA. However, the above-mentioned implementation of the first microstructures 5201 is only an example, and the present application is not limited thereto. In addition, the number of first microstructures 5201 can increase as the number of light-emitting assemblies 3 increases, and the present application is not limited to one light-emitting assembly 3.

[0068] Please refer backFigure 2 The second portion 522 is configured to correspond to the emitter 4 and to provide the ranging beam generated by the emitter 4 with second optical properties. The emitter 4 can be, for example, a vertical cavity surface emitting laser (VCSEL). The ranging beam generated by the emitter 4 can have a second field of view FOV2 after passing through the second portion 522. In an alternative embodiment, the second field of view FOV2 can be in the range of 25 to 85 degrees. In some embodiments, the ranging beam can already have a suitable field of view and the field of view of the ranging beam can be unchanged by changing the design of the second portion 522.

[0069] Based on the above architecture, the first portion 520 can provide the illumination beam generated by the light emitting assembly 3 with first optical properties, such as a first field of view FOV1, after the illumination beam generated by the light emitting assembly 3 passes through the first portion 520. In an alternative embodiment, the first field of view FOV1 can be in the range of 65 to 85 degrees. The first portion 520 can cause the illumination beam to generate light rays at a large angle or uniform light rays to improve the overall brightness of the subject when taking a picture with a lens or to increase the illumination range when used as a flashlight.

[0070] Please refer to Figure 2 The second portion 522 is configured to correspond to the emitter 4 and to provide the ranging beam generated by the emitter 4 with second optical properties. The emitter 4 can be, for example, a vertical cavity surface emitting laser (VCSEL). The ranging beam generated by the emitter 4 can have a second field of view FOV2 after passing through the second portion 522. In an alternative embodiment, the second field of view FOV2 can be in the range of 25 to 85 degrees. In some embodiments, the ranging beam can already have a suitable field of view and the field of view of the ranging beam can be unchanged by changing the design of the second portion 522. In the present embodiment, the first field of view FOV1 and the second field of view FOV2 can be adjusted by changing the distance between the optical assembly 5 and the light emitting assembly 3 and the emitter 4.

[0071] [Advantages of the embodiments]

[0072] One of the advantages of the present application is that the electronic device and the ranging module provided by the present application share the light-transmitting portion between the emitter and the light emitting assembly, which can reduce the number of openings on the electronic device, thereby effectively increasing the proportion of the screen display area and improving the user experience of the user.

[0073] Further, the optical assembly has different portions corresponding to the light emitting assembly and the emitter respectively, and provides different optical characteristics for the light emitting assembly and the emitter, so as to achieve various optical effects, effectively utilize the space inside the electronic device, and save production cost.

[0074] Further, the utility model can adjust the ranging capability (e.g., the farthest ranging distance) of the emitter by changing the optical structure of the optical assembly corresponding to the emitter.For example, when a through hole is used to replace the planar lens arranged at the sub-portion, the ranging capability can be improved.In addition, the size of the through hole is also related to the ranging capability, and in some embodiments, the ranging capability increases with the increase of the size of the through hole.
