[0040] The following will be combined with Figures 1 to 23 Describe the screen module 100 and the electronic device according to the embodiments of the present application.

[0041] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 5As shown, a screen module 100 according to some embodiments of the present application includes a screen 110, a light guide component 130, and a light-emitting component 200. The light guide component 130 is disposed on the back of the screen 110 and is arranged along the edge of the screen 110. The light-emitting component 200 is disposed on the back of the screen 110, and at least part of the light-emitting component 200 is located in the first installation groove 122. The light-emitting component 200 includes a light-emitting part 210, and the light-emitting part 210 can emit light toward the light guide component 130, and the light can pass through the light guide component 130 and pass through the screen 110.

[0042] In this embodiment, the screen module 100 includes a light guide component 130 and a light-emitting component 200. The light guide component 130 is disposed on the back of the screen 110 and is arranged along the edge of the screen 110. The light-emitting component 200 includes a light-emitting part 210, and the light-emitting part 210 can emit light toward the light guide component 130. After the light emitted by the light-emitting part 210 is transmitted to the light guide component 130, the light is transmitted along the light guide component 130, so that a light ring can be formed at the outer peripheral edge of the screen 110.

[0043] When the electronic device takes a picture through the front camera module, the light-emitting part 210 can emit light toward the light guide component 130. The light can pass through the light guide component 130 and pass through the screen 110, and is transmitted to the front of the electronic device to supplement light for the front camera module to take pictures, thereby improving the shooting effect of the front camera module in a relatively dark environment. And because the light guide component 130 can form a light ring at the outer peripheral edge of the screen 110 with the light generated by the light-emitting part 210, the light supplement range of the light-emitting part 210 is increased. The light guide component 130 can form a light ring at the outer peripheral edge of the screen 110 with the light generated by the light-emitting part 210. When the front camera module takes pictures, the light-emitting part 210 and the light guide component 130 supplement light for the space in front of the electronic device more evenly, improving the light supplement effect of the light-emitting part 210 and further improving the shooting effect of the front camera module in a relatively dark environment. And the light is transmitted to the front of the screen 110 after passing through the screen 110, reducing the limitation of the gap between the screen 110 and the middle frame of the electronic device on the light transmission, further increasing the light supplement range of the light-emitting part 210, and thus improving the light supplement effect of the light-emitting part 210.

[0044] The electronic device uses the light-emitting component 210 and the light-guiding component 130 to provide fill light for the front camera module during shooting. The light-emitting component 210 can be turned on or off according to the needs of the front camera module, thereby reducing the power loss caused by the constant lighting of the light-emitting component 210 and improving the standby time of the electronic device. Compared with the fill light for the front camera module through the screen 110, the fill light for the front camera module through the light-emitting component 210 and the light-guiding component 130 has a better fill light effect, and the screen 110 no longer needs to be bright for a long time, thereby avoiding the discomfort of the bright screen 110 in a relatively dark environment to the user, further improving the quality of the electronic device.

[0045] Furthermore, the light emitting component 210 is a lamp bead.

[0046] The light guiding member 130 is an optical fiber.

[0047] Furthermore, the screen 110 includes a cover plate and a display component, the display component may be a liquid crystal display component, the lamp housing 120 is against the cover plate and is arranged around the display component so that the light guide component 130 avoids the display component, thereby allowing the light emitting component 210 to transmit light more directly to the outside of the electronic device through the light guide component 130.

[0048] Specifically, the back of the screen 110 is the side of the screen close to the main board of the electronic device.

[0049] According to some embodiments of the present application, the screen module 100 also includes a lamp housing 120, which is connected to the screen 110, and the lamp housing 120 has a first mounting groove 122, and the groove 124 of the first mounting groove 122 faces the screen 110; the light guide component 130 is arranged in the first mounting groove 122 and extends along the lamp housing 120; at least part of the light-emitting component 200 is located in the first mounting groove 122.

[0050] In this embodiment, the screen module 100 includes a screen 110 and a lamp housing 120. The lamp housing 120 is arranged along the outer peripheral edge of the screen 110. The lamp housing 120 has a first mounting groove 122. The notch 124 of the first mounting groove 122 faces the screen 110, that is, the screen 110 covers the notch 124 of the first mounting groove 122. The light guide component 130 is arranged in the first mounting groove 122 and extends along the lamp housing 120. At least part of the light emitting assembly 200 is located in the first mounting groove 122. Since the screen 110 covers the notch 124 of the first mounting groove 122, the light guide component 130 located in the first mounting groove 122 can transmit light through the notch 124 to the front of the electronic device.

[0051] The electronic device installs and fixes the light guide component 130 through the lamp housing 120 provided with the first installation groove 122, improving the stability of the position of the first light guide component 130; the notch 124 of the first installation groove 122 faces the screen 110, enabling the light transmitted by the light guide component 130 to be transmitted to the outside of the electronic device through the screen 110, and the light is no longer affected by the gap between the screen 110 and the middle frame, further improving the light supplement range of the light emitting component 210, and thus improving the light supplement effect of the light emitting component 210.

[0052] Furthermore, the first installation groove 122 is a U-shaped groove.

[0053] According to some embodiments of the present application, as Figure 2 and Figure 5 shown, the screen module 100 further includes a fixing component 140, and the fixing component 140 covers at least a part of the outer surface of the lamp housing 120 and is connected to the screen 110.

[0054] In this embodiment, the fixing component 140 covers at least a part of the outer surface of the lamp housing 120 and is connected to the screen 110, and thus fixes the lamp housing 120 through the fixing component 140, enabling the lamp housing 120, the light guide component 130 and the screen 110 to form an integral module, that is, the lamp housing 120. The light guide component 130 and the screen 110 can be first assembled into a component, and then the screen module 100 can be assembled to the middle frame, reducing the installation difficulty of the light guide component 130 and the lamp housing 120, simplifying the assembly process of the light guide component 130 and the lamp housing 120, and thus improving the assembly efficiency of the light guide component 130 and the lamp housing 120. And by providing the fixing component 140 on the screen 110, the fixing component 140 can reduce the non-display area on the screen 110, and thus improve the display effect of the screen 110.

[0055] Furthermore, the fixing component 140 covers the outside of the lamp housing 120, and the fixing component 140 for fixing the lamp housing 120 can be an original structure of the screen module 100, encapsulating the lamp housing 120 and the light guide component 130 inside the fixing component 140. While achieving the installation and fixation of the lamp housing 120 and the light guide component 130, it will not increase the occupancy of the internal space of the electronic device by the screen module 100, and thus avoid the increase in the thickness of the electronic device due to the addition of the light guide component 130, which is beneficial to the thin and light design of the electronic device.

[0056] Furthermore, the fixing component 140 can be formed on the back of the screen 110 by low-pressure injection molding (Low Injection Pressure Over-molding, LIPO).

[0057] According to some embodiments of the present application, as Figure 6 、 Figure 7 andFigure 8 As shown, an opening 126 is provided on the bottom wall of the lamp housing 120. The opening 126 is used to install the light-emitting component 200. The light-emitting component 200 includes a support member 220 and a flexible circuit board 230. The support member 220 is disposed at the opening 126, and at least a part of the support member 220 is located in the first installation groove 122; the flexible circuit board 230 is disposed on the support member 220, and the light-emitting member 210 is disposed on the flexible circuit board 230.

[0058] In this embodiment, the support member 220 is disposed at the opening 126, at least a part of the support member 220 is located in the first installation groove 122, and the flexible circuit board 230 (Flexible Printed Circuit, FPC) is disposed on the support member 220. Thus, the support member 220 is used to support the flexible circuit board 230, improving the stability of the flexible circuit board 230 inside the lamp housing 120. The light-emitting member 210 is disposed on the flexible circuit board 230. The electronic device can control the light-emitting member 210 through the flexible circuit board 230. When the electronic device takes a picture through the front camera module, it controls the light-emitting member 210 to emit light, thereby realizing fill light during the process of the front camera module taking pictures; when the front camera module of the electronic device is not working, the electronic device controls the light-emitting member 210 to stop emitting light, reducing the power consumption caused by the constant lighting of the light-emitting member 210 and extending the working duration of the battery of the electronic device.

[0059] An opening 126 is provided on the bottom wall of the lamp housing 120. The support member 220 is disposed at the opening 126. The support member 220 can be installed in the first installation groove 122 through the opening 126, reducing the assembly difficulty of the support member 220 and improving the assembly efficiency of the support member 220.

[0060] Furthermore, the electronic device includes a main board and a middle frame. The main board is disposed on the middle frame, the screen module 100 is covered on the middle frame, and the flexible circuit board 230 is electrically connected to the main board, thereby realizing the power supply and control of the light-emitting member 210.

[0061] The support member 220 is in a block shape, embedded in the first installation groove 122 and located at the opening 126.

[0062] Furthermore, the opening 126 of the lamp housing 120 penetrates through the fixing member 140.

[0063] According to some embodiments of the present application, such as Figure 2 , Figure 5 , Figure 9 and Figure 10As shown, the first end of the light guide component 130 is located on the first side of the support component 220, and the second end of the light guide component 130 extends in a ring shape to the second side of the support component 220; the flexible circuit board 230 extends from the first side of the support component 220 to the second side of the support component 220; the light emitting component 210 includes a first light bead 212 and a second light bead 214; the first light bead 212 is disposed on the flexible circuit board 230, located on the first side of the support component 220, and is disposed opposite to the first end of the light guide component 130, and the light generated by the first light bead 212 can be transmitted from the first side of the light guide component 130 to the light guide component 130; the second light bead 214 is disposed on the flexible circuit board 230, located on the second side of the support component 220, and is disposed opposite to the second end of the light guide component 130, and the light generated by the second light bead 214 can be transmitted from the second side of the light guide component 130 to the light guide component 130.

[0064] In this embodiment, the first end of the light guide component 130 is located on the first side of the support component 220, and the second end of the light guide component 130 extends in a ring shape to the second side of the support component 220, so that the light guide component 130 forms a continuous ring structure at the outer peripheral edge of the screen 110, further increasing the light emitting range of the light guide component 130 and improving the light supplement effect after the cooperation of the light emitting component 210 and the light guide component 130.

[0065] The light emitting component 210 includes a first light bead 212 and a second light bead 214; both the first light bead 212 and the second light bead 214 are disposed on the flexible circuit board 230, and thus the support and control of the first light bead 212 and the second light bead 214 are realized through the flexible circuit board 230.

[0066] The flexible circuit board 230 extends from the first side of the support component 220 to the second side of the support component 220. The first light bead 212 is located on the first side of the support component 220, and the second light bead 214 is located on the second side of the support component 220, that is, the first light bead 212 can emit light toward the first end of the light guide component 130, and the second light bead 214 can emit light toward the second end of the light guide component 130, so that the light transmitted to the outside of the electronic device by the light guide component 130 is more evenly distributed, further improving the light supplement effect after the cooperation of the light emitting component 210 and the light guide component 130.

[0067] Further, the light guide component 130 is arranged along the outer peripheral edge of the screen 110 to form a ring structure. There is a gap between the first end of the light guide component 130 and the second end of the light guide component 130, and the support component 220 is located in the gap. The first side and the second side of the support component 220 are two opposite sides of the support component 220. The first side of the support component 220 is opposite to the first end of the light guide component 130, and the second side of the support component 220 is opposite to the second end of the light guide component 130.

[0068] The light generated by the first light bead 212 irradiates the first end of the light guide member 130, and is transmitted from the first end of the light guide member 130 to the end of the light guide member 130 close to the bottom of the electronic device. During the transmission of the light on the light guide member 130, part of the light is transmitted to the front space of the electronic device through the opening 126 of the first mounting groove 122 and the screen 110.

[0069] The light generated by the second light bead 214 irradiates the second end of the light guide member 130, and is transmitted from the second end of the light guide member 130 to the end of the light guide member 130 close to the bottom of the electronic device. During the transmission of the light on the light guide member 130, part of the light is transmitted to the front space of the electronic device through the opening 126 of the first mounting groove 122 and the screen 110.

[0070] Specifically, the first light bead 212 and the second light bead 214 may be light-emitting diodes (LEDs).

[0071] The first light bead 212 includes a cold light source bead 216 and a warm light source bead 218.

[0072] The second light bead 214 includes a cold light source bead 216 and a warm light source bead 218.

[0073] According to some embodiments of the present application, as Figure 9 shown, the light-emitting component 210 includes a cold light source bead 216 and a warm light source bead 218. The cold light source bead 216 and the warm light source bead 218 are arranged in parallel on the flexible circuit board 230. The cold light source bead 216 and the warm light source bead 218 are used to adjust the color temperature of the light emitted by the light-emitting component 200.

[0074] In this embodiment, the light-emitting component 210 includes a cold light source bead 216 and a warm light source bead 218. The cold light source bead 216 and the warm light source bead 218 are arranged in parallel on the flexible circuit board 230. The electronic device can control the cold light source bead 216 or the warm light source bead 218 to emit light according to the fill light needs, thereby realizing the adjustment of the color temperature and further improving the shooting effect of the front camera module of the electronic device. The light-emitting component 210 includes a cold light source bead 216 and a warm light source bead 218. While the electronic device realizes the two-color temperature fill light effect, the power consumption is less affected, and the user's experience of the usage duration will not be affected.

[0075] According to some embodiments of the present application, as Figure 11 shown, the support component 220 is bonded to the screen 110.

[0076] In this embodiment, the support component 220 is bonded to the screen 110, realizing the installation and fixation of the support component 220, simplifying the assembly process of the support component 220, and reducing the assembly difficulty of the support component 220.

[0077] Further, the screen module 100 further includes a double-sided tape 240, and the support member 220 is adhered to the screen 110 through the double-sided tape 240. Optionally, the support member 220 is adhered to the cover plate of the screen 110 through the double-sided tape 240.

[0078] According to some embodiments of the present application, such as Figure 2 , Figure 12 and Figure 13 shown, the screen module 100 further includes a light reflecting member 150. The light reflecting member 150 is disposed in the first installation groove 122 and extends along the light guiding member 130.

[0079] In this embodiment, the light reflecting member 150 is disposed in the first installation groove 122 and extends along the light guiding member 130. The light reflecting member 150 is located on a side of the light guiding member 130 away from the notch 124. The light transmitted to the light reflecting member 150 through the light guiding member 130 will be reflected by the light reflecting member 150 to the notch 124, and then transmitted to the front space of the electronic device through the screen 110, improving the utilization rate of the light generated by the light emitting member 210, and further improving the light supplement effect of the light emitting member 210 and the light guiding member 130. And by disposing the light reflecting member 150 in the first installation groove 122, when the light emitting member 210 does not emit light or the light is weak, the light reflecting member 150 can reflect the light to the position where the support member 220 is located, reducing the probability that the light guiding member 130 observed by the user has a crack at the support member 220, reducing the influence of the light guiding member 130 and the light emitting member 210 on the overall appearance of the electronic device, and improving the consistency of the appearance of the electronic device.

[0080] Further, the light reflecting member 150 is arranged on the bottom wall of the first installation groove 122.

The light shielding member 160 is disposed in the first installation groove 122 and extends along the side wall of the first installation groove 122. The light shielding member 160 is disposed in the width direction of the light guiding member 130 ( Figure 13On both sides in the direction indicated by arrow H, the light-shielding member 160 is configured to block light from being transmitted from both sides of the first mounting groove 122 to the outside of the first mounting groove 122.

[0084] In this embodiment, the light-shielding member 160 is disposed in the first mounting groove 122 and extends along the side wall of the first mounting groove 122. The light-shielding member 160 can block the light of the light guide member 130 from being transmitted to the display member of the screen 110, thereby reducing the probability of affecting the display effect of the screen 110 due to the light conducted by the light guide member 130, and further ensuring the normal operation of the screen 110. The light-shielding member 160 is disposed on both sides of the light guide member 130 in the width direction, further improving the light-blocking effect of the light-shielding member 160 on light.

[0085] Specifically, the material of the light-shielding member 160 is polyethylene terephthalate (PET).

[0086] According to some embodiments of the present application, as Figure 12 and Figure 13 shown, the screen module 100 further includes a bracket 170. The bracket 170 is disposed in the first mounting groove 122, and the bracket 170 is provided with a second mounting groove 172; the light guide member 130 is a light guide column 132, and the light guide column 132 is snap-fitted in the second mounting groove 172.

[0087] In this embodiment, the bracket 170 is disposed in the first mounting groove 122, the bracket 170 is provided with a second mounting groove 172, and the light guide column 132 is snap-fitted in the second mounting groove 172. While the bracket 170 can fix the light guide column 132, the light guide column 132 can be made to be at the same height as much as possible, thereby improving the uniformity of light when the electronic device fills light through the light guide column 132.

[0088] Furthermore, the bracket 170 is a metal bracket or a plastic bracket.

[0089] According to some embodiments of the present application, as Figure 13 shown, the diameter of the cross section of the light guide column 132 is a first diameter D; the minimum width of the second mounting groove 172 is a first width L; the first width L is less than the first diameter D.

[0090] In this embodiment, after the light guide column 132 is installed in the second mounting groove 172, since the diameter of the cross section of the light guide column 132 is greater than the minimum width of the second mounting groove 172, the light guide column 132 can be more stably snap-fitted in the second mounting groove 172, reducing the probability of the light guide column 132 disengaging from the second mounting groove 172, and further improving the stability of the light guide column 132 during the use of the electronic device.

[0091] Specifically, after the bracket 170 and the light guide column 132 are installed in the first installation groove 122, the diameter of the cross-section of the light guide column 132 is greater than the minimum width of the second installation groove 172.

[0092] When the bracket 170 and the light guide column 132 are outside the first installation groove 122, the diameter of the cross-section of the light guide column 132 may be greater than the minimum width of the second installation groove 172.

[0093] When the bracket 170 and the light guide column 132 are outside the first installation groove 122, the diameter of the cross-section of the light guide column 132 may not be greater than the minimum width of the second installation groove 172. After the bracket 170 is installed in the first installation groove 122, the bracket 170 is squeezed by the inner wall of the first installation groove 122 and elastically deformed, and then the diameter of the cross-section of the light guide column 132 is greater than the minimum width of the second installation groove 172.

[0094] According to some embodiments of the present application, as Figure 13 shown, the bracket 170 and the first installation groove 122 are in interference fit.

[0095] In this embodiment, the bracket 170 and the first installation groove 122 are in interference fit. The first installation groove 122 fixes the bracket 170 in the first installation groove 122 by the clamping force on the bracket 170, thereby realizing the installation and fixation of the bracket 170.

[0096] Specifically, the bracket 170 and the first installation groove 122 are in interference fit, that is, after the bracket 170 is installed in the first installation groove 122, the bracket 170 is squeezed by the inner wall of the first installation groove 122 and elastically deformed.

[0097] Further, the first bracket 170 includes a seat body and clamping arms. The clamping arms can be two or more.

[0098] The first ends of the clamping arms are connected to the seat body, the second ends of the clamping arms extend towards the notch 124 of the first installation groove 122, a second installation groove 172 is formed between the two clamping arms, and the first ends to the second ends of the clamping arms are divided into three sections in total. The first section of the clamping arm first extends towards the direction close to the inner wall of the first installation groove 122, the second section of the clamping arm then extends towards the direction away from the inner wall of the first installation groove 122, and finally the third section of the clamping arm extends towards the direction close to the inner wall of the first installation groove 122.

[0099] The first section and the second section of the clamping arm are wrapped around the outside of the light guide column 132 and fix the light guide column 132 in the second installation groove 172. One end of the third section of the clamping arm close to the notch 124 of the first installation groove 122 abuts against the inner wall of the first installation groove 122 and elastically deforms towards the direction close to the light guide column 132.

[0100] The width of the second installation groove 172 at the connection between the second section and the third section of the clamping arm is the minimum width of the second installation groove 172.

[0101] According to some embodiments of the present application, when assembling the screen module 100, as Figure 14 and Figure 15 shown, first fix the light-reflecting component 150 inside the lamp housing 120, that is, on the inner bottom wall of the first installation groove 122; as Figure 13 、 Figure 16 and Figure 17 shown, stick the light-shielding component 160 on the side wall of the first installation groove 122, that is, stick the light-shielding component 160 in the X direction and Y direction of the light guide component 130; as Figure 18 and Figure 19 shown, fix the light guide component 130 to the bracket 170. As Figure 20 and Figure 21 shown, then install the assembled light guide component 130 and the bracket 170 into the first installation groove 122. Here, due to the presence of the bracket 170, while playing the role of fixing the light guide component 130, it can ensure that the light guide component 130 is arranged as much as possible in a horizontal plane, ensuring the uniformity of light when supplementing light; the top of the bracket 170 is fixed to the light guide column 132 in the form of a buckle. Because of the existence of the buckle structure, it can ensure that the bracket 170 assembled inside the lamp housing 120 is in interference fit with the inner wall of the first installation groove 122, thereby clamping the light guide component 130.

[0102] Finally, put the assembled lamp housing 120 and the screen 110 together into the low-pressure injection molding mold for fixing. As Figure 22 and Figure 23 shown, to ensure precise fixed cooperation, two symmetric positioning holes 128 are arranged on the lamp housing 120, so that the square positioning holes 128 can be used for positioning cooperation with the mold. The positioning holes 128 can be arranged at the corners of the lamp housing 120.

[0103] According to requirements, perform low-pressure injection molding on the lamp housing 120 and the screen 110. After the injection molding is completed, align the light-emitting component 200 with the fixing component 140 and the opening 126 of the lamp housing 120 for installation: the light-emitting component 210 has been pre-pasted onto the flexible circuit board 230 in advance. Fix and assemble the flexible circuit board 230 and the support component 220 in advance, and then install them together into the injection-molded screen module 100. Bond with the cover plate through the double-sided tape 240 at the bottom of the support component 220, and finally realize the fixation of the light-emitting component 200 and the cover plate. The light-emitting component 200, the light guide component 130 and the screen 110 form an integral screen module 100.

[0104] During the final assembly of the whole machine, the production line electrically connects the flexible circuit board 230 to the main board on the middle frame, or realizes the connection between the flexible circuit board 230 and the main board through a shrapnel, or welds and fixes the flexible circuit board 230 to the main board.

[0105] When the front camera module needs to be used to take pictures in a dark environment, the light-emitting component 210 can be lit, and the light will be transmitted along the light guide component 130 to form a complete supplementary light ring around the screen 110, illuminating the surrounding shooting environment; because the light-emitting component 210 is equipped with two cold light sources and two warm light sources, users can adjust the cold and warm light modes according to their needs to improve the applicability of the shooting environment.

[0106] Due to the presence of the light-shielding component 160, it can ensure that the light will not irradiate inside the screen 110 after the light guide column 132 is lit, affecting the display of the screen 110; at the same time, the presence of the bottom reflective film can ensure that most of the light is irradiated outside the screen 110 and is effectively utilized, improving the light efficiency utilization rate. At the position of the support component 220, since there is no light guide column 132, it is easy to see the fracture seam when the current is relatively dark, and the presence of the reflective component can alleviate this phenomenon, thereby improving the user experience.

[0107] The matching scheme of the light-emitting component 210 is flexible. In addition to the cold and warm light configurations, the layout design of other color lamp beads can also be carried out according to requirements, and different scenarios are lit to enhance the cool appearance.
