[0030] As the bezels of televisions become narrower and narrower, the remote control receiving head and power indicator light of the light source assembly have a certain volume, and the process of installing the receiving head and the power indicator light in the narrower and narrower bezel becomes increasingly difficult. Therefore, the light source assembly is integrated on the circuit board of the display module. Since the circuit board is located on the side of the display module away from the viewer, the light source assembly is located on the side away from the viewer, resulting in insufficient light visibility of the light source assembly and the inability to effectively transmit light from the external remote control device to the light source assembly.
[0031] In order to solve the above technical problems, refer to Figure 1 to Figure 2 As shown, the present application provides a display device, including a display module 10 and a lens 200, wherein the display module 10 includes a light source assembly 100 for emitting and receiving signal light; the lens 200 includes an incident surface 201, a reflective bevel 202, and an exit surface 203 located on different planes, the reflective bevel 202 is located between the incident surface 201 and the exit surface 203, and the reflective bevel 202 is respectively arranged at an angle to the incident surface 201 and the exit surface 203, and the optical path 101 of the signal light passes through the incident surface 201 and the exit surface 203. One of the exit surfaces 203 is projected onto the reflective bevel 202, and the signal light is projected onto the other of the exit surface 203 or the incident surface 201 through the reflective bevel 202. The reflective bevel 202 is provided with a corrugated structure 210, and the corrugated structure 210 extends from a side close to the incident surface 201 to a side close to the exit surface 203. The corrugated structure 210 disperses the signal light to multiple angles and then projects it onto the exit surface 203, or the corrugated structure 210 can gather the dispersed light and then project it onto the incident surface 201.
[0032] When the light source assembly 100 emits and receives light, the light can change the projection angle after being reflected by the reflective bevel 202, and project the light to the front of the display module 10 or receive the light emitted from the front of the display module 10. The reflective bevel 202 is provided with a corrugated structure 210, and the corrugated structure 210 disperses the light to multiple angles and projects it to the exit surface 203, or the corrugated structure 210 can gather the dispersed light and project it to the incident surface 201, thereby improving the visual performance of the light of the light source assembly 100. When the light source assembly 100 emits light, a fan-shaped emission surface can be formed. On the one hand, as shown in Figure 2, when the light source assembly 100 emits light, the light can form a fan-shaped emission surface and then be received by an external remote control device; on the other hand, as shown in Figure 3, when the light source assembly 100 receives light, the corrugated structure 210 on the reflective bevel 202 can gather the light incident in the fan-shaped direction and project it onto the incident surface 201. Thereby, the light transmission area between the light source assembly 100 and the external remote control device is increased, thereby achieving more efficient light transmission between the external remote control device and the light source assembly 100 .
[0033] In some embodiments, reference Figures 1 to 3 As shown, the display module 10 includes a display panel (not shown) and a circuit board 11, and the circuit board 11 is arranged on the rear side of the display panel. The display device also includes a middle frame 20, which can accommodate the display panel. A light source assembly 100 is integrated on the circuit board 11, and the light source assembly 100 emits light in a first direction, the first direction is from the middle of the display device to the bottom of the display device, and the first direction is parallel to the display panel. The light is emitted from the light source assembly 100 to the bottom of the display device.
[0034] In some embodiments, the lens 200 is made of a transparent material, including resin, glass, etc., and light can at least enter from the incident surface 201 and the exit surface 203 and then be conducted inside the lens 200 .
[0035] In some embodiments, the light source assembly 100 includes a remote control receiving head and a power indicator light. The remote control receiving head is used to receive light emitted by an external remote control, and the power indicator light is used to emit light that can indicate whether the power is on.
[0036] In some embodiments, reference Figure 3As shown, the lens 200 includes an incident portion 220 and an exit portion 230 connected to each other, the incident portion 220 is provided with an incident surface 201, the exit portion 230 is provided with an exit surface 203, and a reflective inclined surface 202 is provided at the connection between the incident portion 220 and the exit portion 230, and the angle between the reflective inclined surface 202 and the incident surface 201 and the exit surface 203 is 45°. The incident portion 220 and the exit portion 230 can be used for light projection, and the reflective inclined surface changes the projection angle after reflecting the light from the incident surface 201 or the exit surface 203, wherein the projection angle is 90°, so that the light is projected in the vertical direction.
[0037] In some embodiments, reference Figure 4 As shown, the corrugated structure 210 includes a plurality of arc-shaped portions 211, which are arranged in parallel. The arc-shaped portions 211 are arranged to protrude toward the side away from the incident light of the light source assembly, and each arc-shaped portion 211 extends from the side close to the incident surface 201 to the side close to the exit surface 203. The arc-shaped portion 211 is a partial circular structure. After the light enters from the incident surface 201, it is projected onto the corrugated structure 210. The light is projected in the direction of the included angle through the arc-shaped portion 211. When the light source assembly 100 emits light, Figure 2 The straight line parallel to the left and right direction of the paper is the incident light, and the straight line parallel to the up and down direction of the paper is the outgoing light, wherein the incident light and the outgoing light are on different planes, and the angle between the different planes is 90°. Therefore, when the light source assembly 100 emits light, the light can be projected along the outgoing portion 230 and also projected in the direction of the angle to the outside of the outgoing portion 230, making the light softer; Figure 3 The straight line parallel to the left and right directions of the paper is the outgoing light, and the straight line parallel to the up and down directions of the paper is the incident light. When the lens 200 receives light, the light can be projected from different directions into the incident surface 201 through the corrugated structure 210 on the reflecting slope 202, thereby increasing the light receiving range.
[0038] In some embodiments, reference Figure 5 and Figure 6As shown, the display device further includes a back cover 300, a light source assembly is arranged inside the back cover 300, a lens 200 is arranged on the back cover 300, an incident surface 201 is arranged corresponding to the light source assembly, and at least an exit surface 203 is located outside the back cover 300. The light source assembly 100 is located inside the back cover 300. On the one hand, the incident surface 201 of the lens 200 is located inside the back cover 300, and the exit surface 203 and the reflection inclined surface 202 are located outside the back cover 300; on the other hand, the incident surface 201 and the reflection inclined surface 202 of the lens 200 are located inside the back cover 300, and the exit surface 203 is located outside the back cover 300. At least the exit surface 203 can be located outside the back cover 300, so that the light emitted by the light source assembly 100 is transmitted to the outside of the back cover 300, or the external light can be transmitted to the light source assembly 100 through the lens 200.
[0039] In some embodiments, reference Figure 5 and Figure 6 As shown, the rear cover 300 is provided with a mounting hole 310. The incident portion 220 is provided in the mounting hole 310, part of the incident portion 220 is located inside the rear cover 300, part of the incident portion 220 extends outside the rear cover 300, and the exit portion 230 is located outside the rear cover 300 and extends in a direction perpendicular to the optical path 101 inside the incident portion 220. The incident portion 220 cooperates with the mounting hole 310 to arrange the incident portion 220 at a side close to the light source assembly, so that the incident portion 220 can receive light from the light source assembly 100 or transmit light to the light source assembly 100.
[0040] In some embodiments, reference Figure 5 and Figure 6 As shown, the lens 200 further includes a rib 240 and a protrusion 250. The rib 240 is disposed on the other side of the incident portion 220, and the rib 240 abuts against one side of the mounting hole 310. The protrusion 250 is disposed on one side corresponding to the rib 240, and one side of the protrusion 250 abuts against one side of the mounting hole 310. The protrusion 250 is located in the back cover 300, and the protrusion 250 and the back cover 300 abut against each other. The protrusion 250 cooperates with the mounting hole 310 to achieve the end position limit of the lens 200, and the rib 240 cooperates with the mounting hole 310 to achieve the middle position limit of the lens 200, so that the lens 200 will not be displaced in the mounting hole 310 through the end position limit and the middle position limit, and the lens 200 will not fall off from the back cover 300 through the protrusion 250 abutting against the back cover 300, which is convenient for installation and maintaining the stability of the lens 200.
[0041] In some embodiments, reference Figure 5 and Figure 6As shown, the back cover 300 is provided with a snap-in hole 320. The lens 200 further includes an elastic arm 260, which is connected to the emission portion 230. The elastic arm 260 is extended in a direction perpendicular to the optical path 101 in the emission portion 230. A snap-in portion 261 is provided on the side of the elastic arm 260 away from the emission portion 230. The elastic arm 260 extends into the snap-in hole 320 and is locked with the snap-in hole 320 through the snap-in portion 261. The lens 200 is further fixed on the back cover 300, and the lens 200 is more stably fixed on the back cover 300 through the cooperation between the snap-in portion 261 and the snap-in hole 320, and the cooperation between the protrusion 250 and the mounting hole 310. Since the elastic arm 260 is elastic, the snap-in portion 261 can fall off the snap-in hole 320 when a force is applied to the elastic arm 260, so that the lens 200 can be removed from the back cover 300.
[0042] In some embodiments, reference Figure 5 and Figure 6 As shown, the rear cover 300 is provided with a positioning hole 330. The lens 200 further includes a positioning post 270, which is connected to the emission portion 230. The positioning post 270 is extended in a direction perpendicular to the optical path 101 in the emission portion 230. The positioning post 270 is inserted into the positioning hole 330. The positioning hole 330 and the positioning post 270 cooperate with each other to position the lens 200 and the rear cover 300. During the assembly and disassembly process, due to the positioning function of the positioning hole 330 and the positioning post 270, the lens 200 can be prevented from rotating and shifting during the disassembly and assembly process, and the initial positioning of the lens 200 can also be achieved. It can also facilitate subsequent assembly and disassembly.
[0043] In some embodiments, reference Figure 5 and Figure 6 As shown, the back cover 300 is provided with a groove 340 which is recessed toward the side close to the light source assembly, and part of the emission portion 230 is located in the groove 340. The side of the emission portion 230 away from the incident portion 220 abuts against the side of the groove 340. The groove 340 of the back cover 300 forms a countersunk hole in the back cover 300. The side of the groove 340 is the side of the countersunk hole. The incident portion 220 protrudes on the side close to the back cover 300 and cooperates with the countersunk hole. The side of the countersunk hole cooperates with the protruding structure of the incident portion 220 to show the positioning of one side. Thus, the stability of the lens 200 is maintained.
[0044] In some embodiments, reference Figure 5 and Figure 6As shown, the width of the emitting portion 230 is greater than the width of the incident portion 220 to form a step surface 280, and the step surface 280 abuts against the bottom surface of the groove 340. The step surface 280 and the bottom surface of the groove 340 cooperate with each other to support the lens 200. When the lens 200 is subjected to external pressure, the risk of the step surface 280 collapsing into the back cover 300 due to the external pressure can be reduced, thereby maintaining the stability of the structure of the lens 200 and the back cover 300.
[0045] In the present application, at least the exit surface 203 of the lens 200 is located outside the back cover 300. When the light source assembly 100 emits and receives light, the light can change the projection angle after being reflected by the reflective bevel 202, and the light is projected to the front of the display module 10 or the light emitted from the front of the display module 10 is received. The reflective bevel 202 is provided with a corrugated structure 210, and the corrugated structure 210 disperses the light to multiple angles and projects it to the exit surface 203, or the corrugated structure 210 can gather the dispersed light and project it to the incident surface 201, thereby improving the visual performance of the light of the light source assembly 100. On the one hand, as shown in 2, when the light source assembly 100 emits light, the light can form a fan-shaped emission surface and then be received by the external remote control device; on the other hand, as shown in 3, when the light source assembly 100 receives light, the corrugated structure 210 on the reflective bevel 202 can gather the light incident in the fan-shaped direction and project it onto the incident surface 201. Thereby, the light transmission area between the light source assembly 100 and the external remote control device is increased, thereby achieving more efficient light transmission between the external remote control device and the light source assembly 100 .
