[0062] Figure 3A The partial structure of an electronic device according to an embodiment of the present invention is shown. Figure 3B A cross-sectional view of an electronic device according to an embodiment of the present invention is shown. Figure 2 、 Figure 3A as well as Figure 3B The circuit board 2 is disposed within the housing recess 11. The circuit board 2 includes a first circuit board surface 201 and a plurality of first light sources 51. These first light sources 51 are disposed on the first circuit board surface 201 and provide a first light beam L1. A light guide ring 3 is disposed within the device housing 1 and extends from the housing recess 11 to the exterior of the device housing 1. The light guide ring 3 has a light entrance edge 31 and a light exit edge 32. The first light beam L1 enters the light guide ring 3 through the light entrance edge 31 and exits through the light exit edge 32. The light absorbing elements 41 are supported by the support plate 12 and correspond to the light entrance edge 31.

[0066] Matching reference Figure 2 、 Figure 3A In one embodiment, the light incident edge 31 includes a plurality of recesses 311 and a plurality of protrusions 312. The recesses 311 and protrusions 312 are spaced apart from each other. The first light sources 51 correspond to the recesses 311, and the light absorbing members 41 correspond to the recesses 311.

[0069] Reference Figure 2 、 Figure 3A 、 Figure 3B In one embodiment, the first light sources 51 are arranged in a ring shape and emit the first light beams L1 toward a center of the housing recess 11 (i.e., away from the light guide ring 3). After multiple reflections and scattering between the circuit board 2 and the support plate 12, the first light beams L1 enter the light entrance edge 31 in a relatively uniform manner and are emitted through the light exit edge 32.

[0070] Figure 4 A light guide ring according to another embodiment of the present invention is shown. Figure 4 In this embodiment, the concave portion 311 ′ and the convex portion 312 ′ of the light guide ring 3 ′ are arc-shaped.

[0071] After careful research, the applicant discovered that the primary cause of uneven brightness (bright spots) on conventional light guide rings is that the reflective layer corresponds to the light-entering edge of the light guide ring. At certain angles, users observe light that is reflected by the reflective layer and directly enters the light guide ring, resulting in brighter bright spots. In the embodiments of the present invention, a light-absorbing element is positioned at the light-entering edge of the light guide ring, significantly reducing the amount of light that is reflected by the reflective layer and directly enters the light guide ring, thereby eliminating the uneven brightness on the light guide ring.

Figure 2 、 Figure 5In one embodiment, the electronic device further includes a key light guide plate 62, wherein the interface trim plate 61 covers the circuit board 2, the interface trim plate 61 includes a key area 611, the circuit board 2 includes a second circuit board surface 202 and a plurality of second light sources 52, the second light sources 52 are arranged on the second circuit board surface 202, the surface of the second circuit board 202 is opposite to the first circuit board surface 201, the key light guide plate 62 is arranged between the key area 611 and the circuit board 2, the second light sources 52 are directed toward the key light guide plate 62 and provide a second light L2, the second light L2 enters the key light guide plate 62, and provides illumination from the key light guide plate 62 toward the key area 611.

[0073] Reference Figure 5 In one embodiment, the electronic device further includes a first light shielding ring 71 , which is disposed on the second circuit board surface 202 . The first light shielding ring 71 separates the key light guide plate 62 and the light guide ring 3 .

[0074] Figure 6 Another cross-sectional view of the electronic device according to an embodiment of the present invention is shown. Figure 2 、 Figure 3A as well as Figure 6 In one embodiment, the electronic device E further includes at least one third light source 53, a light guide element 63, and a light-transmitting decorative strip 64. The device housing 1 includes a housing slot 132. The light-transmitting decorative strip 64 is disposed in the housing slot 132. The third light source 53 provides a third light L3. The third light L3 passes through the light guide element 63 and is emitted through the light-transmitting decorative strip 64.

[0075] Matching reference Figure 2 、 Figure 3A as well as Figure 6 In one embodiment, the electronic device further includes a second light shielding ring 72 , wherein the third light source 53 is disposed on the first circuit board surface 201 , and the second light shielding ring 72 surrounds the third light source 53 .

[0076] Reference Figure 6 In one embodiment, the support plate 12 has a support plate through hole 123, a first support plate surface 121, and a second support plate surface 122.

[0077] In this embodiment of the present invention, since the light-absorbing element corresponds to the light-entering edge of the light guide ring, light from the reflective layer is less likely to directly enter the light guide ring, thereby eliminating uneven brightness across the light guide ring and improving the user's visual experience. Furthermore, the first and second light rays are separated by the first light-shielding ring, preventing light mixing. The first and third light rays are also separated by the second light-shielding ring and support plate, similarly preventing light mixing.
