TECHNICAL FIELD

[0001] The present application relates to the field of terminals, and more particularly, to a color display assembly and an electronic device. BACKGROUND

[0002] In order to make the electronic device more beautiful, the manufacturer sets a color display assembly in the area of the electronic device which is easy to be observed by the user, so as to please the user's aesthetic sense. For example, a light-transmitting material is arranged around the display screen, and a light source is arranged to irradiate the light-transmitting material, and the user can observe that the light-transmitting material emits light. In addition, the color, intensity, etc. of the light can be adjusted to change the light-emitting state of the light-transmitting material, for example, the light emitted by the light-transmitting material is red at a first time, and the light emitted by the light-transmitting material is blue at a second time. However, the conventional light source is mostly a linear light source or a point light source, such as an LED light source. The color display effect observed by the user from the light-transmitting material is poor, which is not conducive to improving the beauty of the electronic device. SUMMARY

[0003] The present application provides a color display assembly and an electronic device, which aims to improve the color display effect of the color display assembly.

[0004] In a first aspect, a color display assembly is provided, comprising: an array of light-emitting units, comprising a first light-emitting unit and a second light-emitting unit, the first light-emitting unit and the second light-emitting unit emitting light of different colors; a light guide, a surface of the light guide comprising an incident surface, an exit surface, and a side surface connecting the incident surface and the exit surface, light emitted by the array of light-emitting units being incident on the light guide from the incident surface and being emitted from the exit surface of the light guide after multiple reflections on the side surface; a support provided with the array of light-emitting units and the light guide, the support comprising a cavity, light emitted by the array of light-emitting units being incident on the incident surface of the light guide through the cavity of the support.

[0005] The array of light-emitting units can comprise a plurality of light-emitting units. The light-emitting units can be point light sources or linear light sources. The light-emitting units can be, for example, light emitting diodes (LEDs) or organic light emitting diodes (OLEDs).

[0006] The light emitted by the light-emitting units can not contact the cavity of the support, but be directly incident on the incident surface of the light guide, or can first be incident on the inner wall of the cavity and then be incident on the incident surface of the light guide after one or more reflections. That is, the light of different colors emitted by the array of light-emitting units can be mixed in the cavity. The propagation direction of the light emitted by the array of light-emitting units can be perpendicular to the incident surface of the light guide, or can not be perpendicular to the incident surface of the light guide, i.e., the incident angle is greater than 0°.

[0007] The incident surface can be a plane or a curved surface, for example, can be a horizontal plane, an outward convex curved surface, an inward concave curved surface, etc. The exit surface can be a plane or a curved surface, for example, can be a vertical plane, an outward convex curved surface, an inward concave curved surface, etc. The side surface of the light guide body can be a plane or a curved surface, for example, can be a horizontal plane, an inclined plane, an outward convex curved surface, an inward concave curved surface. In order to make the description clearer, the plane and the curved surface in the present application are all bounded surfaces, that is, the plane or the curved surface in the present application has a certain shape, area and size. In order to make the description clearer, the convex direction of the outward convex curved surface is towards the outside of the light guide body, and the convex direction of the inward concave curved surface is towards the inside of the light guide body.

[0008] In the embodiments of the present application, on the one hand, the light rays incident on the side surface of the light guide body can be reflected multiple times, changing the overall propagation direction of the light rays, prolonging the propagation distance of the light rays, and facilitating the mixing of light; on the other hand, the light rays can produce multiple light rays with different propagation directions after multiple reflections, enhancing the mixing effect of the light. After mixing, light rays of different colors can produce a glare effect, which is different from the mixing effect of white light or single-color light, and has multiple effects such as flowing, breathing and dazzling colors.

[0009] In combination with the first aspect, in some implementations of the first aspect, the light guide body is in a bent shape, a part of the light guide body is located in the cavity, and the other part of the light guide body is located outside the cavity.

[0010] The light guide body in a bent shape means that the light guide body can include a first part, a second part and a bent part connected between the first part and the second part, and the first part and the second part can not be connected.

[0011] In the embodiments of the present application, compared with the light guide body in a non-bent shape, a part of the light guide body in a bent shape extends into the cavity, so that the light guide body in a bent shape is easier to install.

[0012] In combination with the first aspect, in some implementations of the first aspect, the incident surface is a plane, and the light guide body includes a bent part, and a surface of the bent part includes a first side surface, and the first side surface is a plane inclined to the incident surface.

[0013] In the embodiments of the present application, the light mixing of the plane reflective surface mainly comes from the scattering principle of light and the reflection of light. Two light rays with the same propagation direction can be obtained by irradiating different positions of the reflective plane, the light path is easier to predict, and the processing difficulty is low.

[0014] With reference to the first aspect, in some implementations of the first aspect, the incident surface is a plane, the light guide comprises a bending portion, and a surface of the bending portion comprises a first side surface, the first side surface being a convex curved surface, and a tangent plane at any position on the first side surface is inclined to the incident surface.

[0015] In the embodiments of the present application, two light beams with the same propagation direction are incident on different positions of the reflection curved surface, and the two light beams with different propagation directions are likely to be obtained due to the change of the curvature of the curved surface. The light emitted by the curved reflection surface can increase the light mixing effect without changing the number of reflections.

[0016] With reference to the first aspect, in some implementations of the first aspect, the side surface comprises a second side surface and a third side surface intersecting the exit surface, the second side surface is a plane perpendicular to the exit surface, the third side surface is a plane inclined to the exit surface, and the second side surface does not intersect the third side surface.

[0017] In the embodiments of the present application, the light is more likely to be reflected multiple times in the light guide, and the uniformity of different light beams is different, so that the iridescent effect of the iridescent display assembly is better.

[0018] With reference to the first aspect, in some implementations of the first aspect, the side surface comprises a second side surface and a third side surface intersecting the exit surface, the second side surface and / or the third side surface is a curved surface, a tangent plane at any position on the curved surface is inclined to the exit surface, and the second side surface does not intersect the third side surface.

[0019] In the embodiments of the present application, the light is more likely to be reflected multiple times in the light guide, and the uniformity of different light beams is different, so that the iridescent effect of the iridescent display assembly is better.

[0020] With reference to the first aspect, in some implementations of the first aspect, the iridescent display assembly further comprises: a light uniformizing sheet arranged in the cavity of the support and located between the light emitting unit array and the incident surface of the light guide, and the light emitted by the light emitting unit array passes through the light uniformizing sheet and enters the light guide.

[0021] In the embodiments of the present application, the light emitted by the curved reflection surface can increase the light mixing effect without changing the number of reflections.

[0022] With reference to the first aspect, in some implementations of the first aspect, the support comprises a rib on the inner wall of the support, and the light guide and / or the light uniformizing sheet abut against the rib.

[0023] In the embodiments of the present application, the rib is arranged on the support, so that the position of the light guide or the light uniformizing sheet is more easily determined, and the assembly process is simple.

[0024] With reference to the first aspect, in some implementations of the first aspect, the bracket is connected with the light guide body by a screw, and a fixed position of the screw on the light guide body is located outside the irradiation area of the light guide body.

[0025] In the embodiments of the present application, on the one hand, the screw is arranged in the cavity of the bracket, so that the user can not observe the extra components arranged in the exposed area of the electronic device. On the other hand, since the arrangement position of the screw is outside the irradiation area of the light guide body, the screw will not affect the glare effect of the glare display assembly.

[0026] With reference to the first aspect, in some implementations of the first aspect, the first light emitting unit is adjacent to the second light emitting unit, the distance between the center of the first light emitting unit and the center of the second light emitting unit is W, and the distance between the first light emitting unit and the incident surface of the light guide body is H, and the value of H / W is greater than or equal to 0.8.

[0027] In the embodiments of the present application, in the case where the value of H / W is greater than or equal to 0.8, the glare effect of the glare display assembly is better. That is, the closer the arrangement of the light emitting units, or the longer the propagation distance of the light in the cavity, the better the glare effect.

[0028] The second aspect provides an electronic device comprising the glare display assembly according to the first aspect and any possible implementation of the first aspect. BRIEF DESCRIPTION OF DRAWINGS

[0053] The technical solutions in the present application will be described below with reference to the drawings.

[0054] Figure 1 is a structural schematic view of an electronic device provided by an embodiment of the present application.

[0055] The electronic device 100 can be a display, a television, a mobile phone, a tablet computer, an e-book reader, a notebook computer, a vehicle-mounted device, or a wearable device. Figure 1 The illustrated embodiment takes the display as an example to illustrate the electronic device 100.

[0056] The electronic device 100 includes a housing 110 and a screen assembly 120. The screen assembly 120 is mounted to the housing 110. Specifically, the housing 110 includes a frame and a back cover. The frame is arranged around the periphery of the back cover. The periphery of the screen assembly 120 abuts against the inner edge of the frame, and the frame can have a mechanical protection effect on the screen assembly 120. The screen assembly 120 and the back cover are respectively mounted to the two sides of the frame, so that the housing 110 can have a mechanical protection effect on the internal components of the electronic device, especially the components mounted between the screen assembly 120 and the back cover. A user can watch the screen assembly 120 to enjoy media resources such as images and videos. The electronic device 100 can further include a base 130 for fixing the placement orientation of the electronic device 100, such as making the electronic device 100 stand vertically.

[0057] Among them, in order to make the electronic device 100 more beautiful and pleasing to the eye, a color display assembly can also be provided on the electronic device 100. The color display assembly can use a light source so that a user can observe the light emitted by the color display assembly. The color display assembly can be provided on the housing 110 or the base 130.

[0058] The electronic device 100 further comprises a control module. The control module is housed in the electronic device 100. For example, the control module is housed in the housing 110, or is housed in the base 130. The control module can comprise at least one communication interface, a bus, at least one processor and at least one memory. The at least one communication interface, the at least one processor and the at least one memory can communicate with each other through the bus. The at least one communication interface is used to receive and send data. The color display assembly is connected to one of the communication interfaces, so that the control module can start the driving circuit to trigger the light emitting units in the color display assembly to emit light. The at least one memory is used to store program codes. The program codes comprise codes for controlling the light emitting units to emit light or not to emit light, and codes for controlling the light emitting color. The at least one processor can be used to execute the above-mentioned application program codes to realize various light emitting states of the color display assembly. In the present application, "at least one" includes one or more of the two cases.

[0059] Figure 2 Fig. 4 shows a structural schematic diagram of a color display assembly arranged on the base 130. Figure 3 、 Figure 4 Fig. 5 shows an exploded view of another color display assembly. The color display assembly 200 comprises a light emitting unit array 210, a light guide 230, and a support 220.

[0060] The light emitting unit array 210 can comprise a plurality of light emitting units. The light emitting units can be point light sources or line light sources. The light emitting units can be, for example, light emitting diodes (LEDs), organic light emitting diodes (OLEDs). The plurality of light emitting units comprises first light emitting units and second light emitting units, and the color of the light emitted by the first light emitting units is different from the color of the light emitted by the second light emitting units. For example, the first light emitting units emit red light, and the second light emitting units emit blue light. Figure 1 The control module in the electronic device 100 shown in Fig. 5 can be used to control the light emitting state of the light emitting unit array 210, which can include the light emitting time, the light emitting period, the light emitting intensity, the light emitting color, etc. For example, at a first time, the first light emitting units emit red light, and the second light emitting units do not emit light; at a second time, the first light emitting units emit red light, and the second light emitting units emit blue light; at a third time, the first light emitting units do not emit light, and the second light emitting units emit blue light.

[0061] The support 220 contains a cavity in addition to supporting and fixing the light emitting unit array 210 and the light guide 230. Light emitted by the light emitting unit array 210 passes through the cavity and irradiates the incident surface 231 of the light guide 230. The light emitted by the light emitting unit array 210 can directly irradiate the incident surface 231 of the light guide 230 without contacting the cavity, or can first irradiate the inner wall of the cavity and then irradiate the incident surface 231 of the light guide 230 after one or more reflections. On the one hand, the scattering of light allows the mixing of light even without contacting the cavity; on the other hand, the light not contacting the cavity can mix with the light reflected by the inner wall of the cavity. That is, different colors of light emitted by the light emitting unit array 210 can mix in the cavity. The light emitting unit array 210 can be mounted on the inner wall of the support 220 (as shown in Figure 2 ), so that the light emitted by the light emitting unit array 210 can enter the cavity of the support 220. Alternatively, the support 220 can include a cover plate 221 (as shown in Figure 3 ), and the light emitting unit array 210 can be mounted on the side of the cover plate 221 facing the cavity, so that the light emitted by the light emitting unit array 210 can enter the cavity of the support 220. The mounting method of the light emitting unit array 210 is not limited in the present application. Figure 2 、 Figure 3 The embodiments shown in

[0062] The surface of the light guide 230 includes the incident surface 231, the exit surface 232, and the side surface connecting the incident surface 231 and the exit surface 232. The incident surface 231 can be a plane or a curved surface, for example, a horizontal plane, an outward convex curved surface, an inward concave curved surface, etc. The incident surface 231 is represented by a black solid figure as shown in Figure 3 、 Figure 4 The exit surface 232 can be a plane or a curved surface, for example, a vertical plane, an outward convex curved surface, an inward concave curved surface, etc. The exit surface 232 is represented by a black solid figure as shown in Figure 3 、 Figure 4 The side surface of the light guide 230 can be a plane or a curved surface, for example, a horizontal plane, an inclined plane, an outward convex curved surface, an inward concave curved surface.

[0063] Light enters the light guide 230 from the incident surface 231 of the light guide 230, and is reflected multiple times on the side surface of the light guide 230 before exiting from the exit surface 232 of the light guide 230. The side surface where reflection can occur is, for example, a horizontal plane, an inclined plane, an outward convex curved surface, an inward concave curved surface, etc. as shown in Figure 3The first side surface 233, the second side surface 234, and the third side surface 235 are shown, wherein the second side surface 234 and the third side surface 235 each intersect the exit surface 232. The side surface on which reflection of light can occur is, for example, as shown in FIG. 2B. Figure 4 The first side surface 233, the second side surface 234, and the third side surface 235 are shown, wherein the second side surface 234 and the third side surface 235 each intersect the exit surface 232. Figure 3 Figure 4 The first side surface 233 is represented by a surface filled with diagonal lines. Figure 3 Figure 4 The second side surface 234 is represented by a surface filled with squares. Figure 3 Figure 3 The third side surface 235 is represented by a surface filled with dots.

[0064] For the purpose of making the description clearer, the plane and the curved surface in the present application are all bounded surfaces, i.e., the plane or the curved surface in the present application has a certain shape, area, and size. For example, Figure 4 As shown, the incident surface 231 is coplanar with the second side surface 234. Due to the existence of the cavity, the region in which light rays enter the light guide 230 is only the region in which the incident surface 231 is located, and light rays cannot enter the light guide 230 from the region in which the second side surface 234 is located. Therefore, the shape, area, and size of the incident surface 231 can be determined according to the region in which light rays enter the light guide 230. Similarly, the shape, area, and size of the exit surface 232 can be determined according to the region in which light rays exit the light guide 230. The surface of the light guide 230 other than the incident surface 231 and the exit surface 232 is the side surface of the light guide 230.

[0065] For the purpose of making the description clearer, the convex direction of the convex curved surface is toward the outside of the light guide 230, and the convex direction of the concave curved surface is toward the inside of the light guide 230.

[0066] Optionally, the light guide 230 is in a bent shape, a part of the light guide 230 is located in the cavity, and the other part of the light guide 230 is located outside the cavity.

[0067] The bent shape of the light guide 230 means that the light guide 230 can include a first part 236, a second part 238, and a bent part 237 connected between the first part 236 and the second part 238, and the first part 236 and the second part 238 can not be connected. Figure 5 ​​​The light guide 230 shown is a non-bent light guide, which does not include a bent portion. In addition, in the present application, the light guide including a bent portion does not mean that the shape of the light guide is bent. For example, the shape of the light guide is cylindrical, and the light is injected from one end of the cylinder and emitted from the other end of the cylinder. The cylinder includes a bent portion, but the first portion and the second portion connected with the bent portion are connected, and therefore the cylindrical light guide (the light is injected from one end of the cylinder and emitted from the other end of the cylinder) does not belong to the bent light guide. Figures 6 to 17 The light guide 230 shown is a bent light guide. The first portion 236 extends into the cavity of the support 220, and the bent portion 237 and the second portion 238 are located outside the cavity of the support 220. The first side surface 233 is the surface of the bent portion 237. Compared with the non-bent light guide, the bent light guide has a portion extending into the cavity, and therefore the bent light guide is easier to install.

[0068] The propagation direction of the light emitted by the light emitting unit array 210 can be perpendicular to the incident surface 231 of the light guide 230, or can not be perpendicular to the incident surface 231 of the light guide 230, that is, the incident angle is greater than 0°. When the incident angle is not 0°, the light will be refracted when entering the light guide 230. The present application is described by taking the light vertically entering the light guide 230 as an example. Those skilled in the art will think of many improvements and other embodiments of the present application under the guidance of the foregoing description and the related drawings. Therefore, it should be understood that the present application is not limited to the specific embodiments disclosed.

[0069] In order to realize the reflection of the light on the side surface of the light guide, a reflection structure can be arranged close to part or all of the side surface of the light guide, and the reflection surface of the reflection structure for reflecting the light is close to the side surface of the light guide. "Close to the side surface of the light guide" means that the distance between the reflection surface and the side surface of the light guide is less than a predetermined threshold. When the distance between the reflection surface and the side surface of the light guide is 0, the position where the light is reflected can be the side surface of the light guide. When the distance between the reflection surface and the side surface of the light guide is not 0, the actual position where the light is reflected is the reflection surface of the reflection structure, but the distance between the reflection surface of the reflection structure and the side surface of the light guide is very small, and it can be approximately considered that the light is reflected on the side surface of the light guide. The reflection structure can be, for example, a mirror coating, a mirror glass, etc. The reflection surface can be a mirror surface. The reflection structure can be, for example, Figures 6 to 17 The first reflection structure 341 and the second reflection structure 342 shown.

[0070] On one hand, the light rays incident on the side surface of the light guide can be reflected multiple times, changing the overall propagation direction of the light rays, prolonging the propagation distance of the light rays, and facilitating the mixing of the light. On the other hand, the light rays can generate multiple light beams with different propagation directions after multiple reflections, enhancing the mixing effect of the light. After the mixing of light beams of different colors, a sparkling effect can be generated, which is different from the mixing effect of white light or light of a single color, and has multiple effects such as flowing, breathing, and sparkling.

[0071] The difference between the curved side surface and the planar side surface will be described below. Two light beams with the same propagation direction incident on different positions of a reflecting plane can generate two reflected light beams with the same propagation direction. The direction of the tangent plane at any position on the curved side surface is different, so two light beams with the same propagation direction incident on different positions of the reflecting curved surface can generate two reflected light beams with different propagation directions due to the change in the curvature of the curved surface. The mixing of light by the planar reflecting surface is mainly based on the scattering principle and the reflection of light, while the curved reflecting surface can generate two reflected light beams with different propagation directions. Therefore, the light emitted by the curved reflecting surface can increase the mixing effect of the light without changing the number of reflections. The designer of the light guide can design the side surface (such as one or more of the first side surface 233, the second side surface 234, and the third side surface 235) of the light guide to be planar or curved, as well as the size, shape, and orientation of the side surface relative to the incident surface or the exit surface, so that the light rays can propagate in the light guide according to a predetermined propagation mode.

[0072] On one hand, the light rays incident on the third side surface can be reflected, changing the overall propagation direction of the light rays. On the other hand, the light rays can scatter during propagation, and the scattering phenomenon of the light is more obvious after the reflection of the light by the first side surface, the second side surface, and the third side surface, so that the light rays can be fully mixed. Since the light rays can be reflected multiple times, in some cases, the mixing of multiple light beams with different propagation directions can occur.

[0073] Multiple reflections of the light rays in the light guide can make the scattering phenomenon of the light more obvious and can fully mix the light rays. However, multiple reflections of the light rays in the light guide can reduce the intensity of the light rays. Therefore, the designer of the light guide can reasonably design the size, shape, and orientation of the reflecting surface relative to the incident surface or the exit surface, so that the light rays can be reflected a sufficient number of times in the light guide without excessively reducing the intensity of the light rays exiting the exit surface of the light guide.

[0074] The design points of the bent light guide will be described in detail below with reference to the following example. Figure 6 For a clearer description, the incident surface of the light guide is taken as the horizontal plane, and the exit surface of the light guide is taken as the vertical plane. The orientation of the side surface of the light guide will be described in conjunction with the incident surface or the exit surface. Figure 6The embodiments shown are merely to help those skilled in the art better understand the technical solutions of this application, and are not intended to limit the technical solutions of this application. With the guidance and inspiration presented in the foregoing description and related drawings, those skilled in the art will conceive of many improvements and other embodiments of this application, such as the design principles of non-bent light guides. Therefore, it should be understood that this application is not limited to the specific embodiments disclosed.

[0075] Figure 6 The diagram shows a schematic of a colorful display component provided in this application. The colorful display component 400 includes a light-emitting unit array 410, a light guide 430, and a support 420. The light-emitting unit array 410 includes light-emitting units with different emitting colors. The support 420 is used to support and fix the light-emitting unit array 410 and the light guide 430, and the support 420 includes a cavity. The light emitted by the light-emitting unit array 410 passes through the cavity and illuminates the incident surface 431 of the light guide 430. After multiple reflections on the side surface of the light guide 430, the light is emitted from the exit surface 432 of the light guide 430. To achieve reflection of light on the side surface of the light guide 430, a reflective structure can be provided close to part or all of the side surface of the light guide 430. Figure 7 (Not shown), the reflective surface of the reflective structure for reflecting light is in close contact with the side of the light guide 430. The reflective structure can be, for example, a mirror coating, mirror glass, etc. The reflective surface can be a mirror. Figure 7 A schematic diagram showing the reflection of light on the first side surface 433 and the second side surface 434 of the light guide 430 is shown. The first side surface 433 is a plane inclined to the incident surface 431 (i.e., neither horizontal nor vertical), while the second side surface 434 and the third side surface 435 are both planes parallel to the incident surface 431 (or perpendicular to the exit surface 432) (i.e., both the second side surface 434 and the third side surface 435 are horizontal). The first side surface 433 is the surface of the bent portion 436 of the light guide 430; both the second side surface 434 and the third side surface 435 intersect the exit surface 432, while the second side surface 434 and the third side surface 435 do not intersect.

[0076] Figure 6 The diagram shows a schematic of a colorful display component provided in this application. The colorful display component 500 includes a light-emitting unit array 510, a light guide 530, and a support 520. The light-emitting unit array 510 includes light-emitting units with different emitting colors. The support 520 is used to support and fix the light-emitting unit array 510 and the light guide 530, and the support 520 includes a cavity. The light emitted by the light-emitting unit array 510 passes through the cavity and illuminates the incident surface 531 of the light guide 530. After multiple reflections on the side surface of the light guide 530, the light is emitted from the exit surface 532 of the light guide 530. To achieve reflection of light on the side surface of the light guide 530, a reflective structure can be provided close to part or all of the side surface of the light guide 530.Figure 7 The reflecting surface of the reflecting structure (not shown) for reflecting light is close to the side surface of the light guide 530. The reflecting structure can be a mirror coating, a mirror glass, etc. The reflecting surface can be a mirror. The first side surface 533 and the second side surface 534 of the light guide 530 are both planes (i.e. neither horizontal nor vertical) inclined to the incident surface 531, and the third side surface 535 is a plane (i.e. the third side surface 535 is a horizontal surface) parallel to the incident surface 531 (or perpendicular to the exit surface 532). Among them, the first side surface 533 is the surface of the bending portion 536 of the light guide 530; the second side surface 535 and the third side surface 535 both intersect with the exit surface 532, and the second side surface 535 does not intersect with the third side surface 535. Since the first side surface 533 is the surface of the bending portion 536 of the light guide 530, the first side surface 533 is not parallel to the incident surface 531, and the first side surface 533 is not perpendicular to the exit surface 532. Figure 6 The inclination angle of the second side surface 434 of the light guide 430 shown in FIG. 4 is different from the inclination angle of the second side surface 534 of the light guide 530 shown in FIG. 5. Figure 7 The inclination angle of the second side surface 534 of the light guide 530 shown in FIG. 5 is different from the inclination angle of the second side surface 434 of the light guide 430 shown in FIG. 4. Figure 6 Compared with the light guide 430 shown in FIG. 4, light is more likely to be reflected multiple times in the light guide 530 shown in FIG. 5. Figure 7 Compared with the light guide 430 shown in FIG. 4, light is more likely to be reflected multiple times in the light guide 530 shown in FIG. 5. Figure 8 As shown in FIG. 4, most of the light propagating in the light guide 430 fails to irradiate on the third side surface 435 of the light guide 430, while most of the light propagating in the light guide 530 shown in FIG. 5 can irradiate on the third side surface 535 of the light guide 530, even multiple times. Multiple reflections can introduce the effects of enhancing light mixing and reducing light intensity. Figure 8 As shown in FIG. 4, most of the light propagating in the light guide 430 fails to irradiate on the third side surface 435 of the light guide 430, while most of the light propagating in the light guide 530 shown in FIG. 5 can irradiate on the third side surface 535 of the light guide 530, even multiple times. Multiple reflections can introduce the effects of enhancing light mixing and reducing light intensity.

[0077] Figure 6 FIG. 6 shows a structure schematic diagram of a color display assembly provided by the present application. The color display assembly 600 includes a light emitting unit array 610, a light guide 630, and a support 620. The light emitting unit array 610 includes light emitting units with different light emitting colors. The support 620 is used to support and fix the light emitting unit array 610 and the light guide 630, and the support 620 includes a cavity through which light emitted by the light emitting unit array 610 irradiates on the incident surface 631 of the light guide 630 and is emitted from the exit surface 632 of the light guide 630 after multiple reflections on the side surface of the light guide 630. In order to realize the reflection of light on the side surface of the light guide 630, a reflecting structure (not shown) can be arranged close to part or all of the side surface of the light guide 630. Figure 8The reflecting surface of the reflecting structure (not shown) for reflecting light is close to the side surface of the light guide 630. The reflecting structure can be a mirror coating, a mirror glass, or the like. The reflecting surface can be a mirror surface. The first side surface 633 and the third side surface 635 of the light guide 630 are both planes (i.e., neither horizontal nor vertical) inclined to the incident surface 631, and the second side surface 634 is a plane (i.e., the second side surface 634 is a horizontal surface) parallel to the incident surface 631 (or perpendicular to the exit surface 632). Among them, the first side surface 633 is the surface of the bending portion 636 of the light guide 630; the second side surface 635 and the third side surface 635 both intersect with the exit surface 632, and the second side surface 635 does not intersect with the third side surface 635. Since Figure 6 The inclination angle of the third side surface 435 of the light guide 430 shown in FIG. 4 is different from that of the third side surface 635 of the light guide 630 shown in FIG. 6. Figure 8 The inclination angle of the third side surface 635 of the light guide 630 shown in FIG. 6 is different from that of the third side surface 435 of the light guide 430 shown in FIG. 4. Figure 8 Compared with the light guide 430 shown in FIG. 4, the light incident to the light guide 630 shown in FIG. 6 cannot be reflected on the third side surface 635 of the light guide 630.

[0078] Figure 7 The part of the light incident to the light guide 630 shown in FIG. 6 can be reflected on the third side surface 635 of the light guide 630, while the other part of the light incident to the light guide 630 cannot be reflected on the third side surface 635 of the light guide 630, so that the light reflected by the third side surface 635 has a better light mixing effect and a lower light intensity. Therefore, Figure 7 The light guide 630 shown in FIG. 6 can homogenize a small part of the light propagating in the light guide 630. Compared with the light guide 430 shown in FIG. 4, Figure 8 Since the second side surface 534 of the light guide 530 shown in FIG. 5 is an inclined surface, and the second side surface 634 of the light guide 630 shown in FIG. 6 is a horizontal surface, the light is more likely to be reflected multiple times in the light guide 530 shown in FIG. 5. Figure 9 The light is more likely to be reflected multiple times in the light guide 530 shown in FIG. 5. Figure 9 The light guide 630 shown in FIG. 6 is more likely to homogenize a small part of the light propagating in the light guide 630.

[0079] Figure 9 FIG. 7 shows a structure schematic diagram of a color display assembly provided by the present application. The color display assembly 700 includes a light emitting unit array 710, a light guide 730, and a support 720. The light emitting unit array 710 includes light emitting units with different light emitting colors. The support 720 is used to support and fix the light emitting unit array 710 and the light guide 730, and the support 720 includes a cavity through which the light emitted by the light emitting unit array 710 is incident on the incident surface 731 of the light guide 730 and is emitted from the exit surface 732 of the light guide 730 after being reflected multiple times on the side surface of the light guide 730. In order to realize the reflection of the light on the side surface of the light guide 730, a reflecting structure (not shown) can be arranged close to part or all of the side surface of the light guide 730. Figure 8(Not shown), the reflective surface of the reflective structure used to reflect light is in close contact with the side of the light guide 730. The reflective structure can be, for example, a mirror coating, mirror glass, etc. The reflective surface can be a mirror. The first side 733, the second side 734, and the third side 735 of the light guide 730 are all planes inclined to the incident surface 731 (i.e., neither horizontal nor vertical). Among them, the first side 733 is the surface of the bent portion 736 of the light guide 730; the second side 735 and the third side 735 both intersect with the exit surface 732, but the second side 735 and the third side 735 do not intersect. Because Figure 9 The second side 734 and the third side 735 shown are both inclined surfaces. Therefore, they can cause multiple reflections of light within the light guide 730, and can also cause non-uniform homogenization (or partial homogenization) of the light beam. That is, the homogenization effect of a portion of the beam can differ from the homogenization effect of other beams. Figure 9 Unlike the light guide 630 shown, because the light is in Figure 10 Multiple reflections can occur within the light guide 730 shown, and light beams with different homogenization effects can mix with each other, producing a diverse mixing effect of light. The light mixing effect of the light guide with a curved third side is... Figure 10 The light guide shown is similar to the 730.

[0080] Figure 10 The diagram shows a schematic of a colorful display component provided in this application. The colorful display component 800 includes a light-emitting unit array 810, a light guide 830, and a support 820. The light-emitting unit array 810 includes light-emitting units with different emitting colors. The support 820 is used to support and fix the light-emitting unit array 810 and the light guide 830, and the support 820 includes a cavity. The light emitted by the light-emitting unit array 810 passes through the cavity and illuminates the incident surface 831 of the light guide 830. After multiple reflections on the side surface of the light guide 830, the light is emitted from the exit surface 832 of the light guide 830. To achieve reflection of light on the side surface of the light guide 830, a reflective structure can be provided close to part or all of the side surface of the light guide 830. Figure 10 (Not shown), the reflecting surface of the reflecting structure used to reflect light is in close contact with the side of the light guide 830. The reflecting structure can be, for example, a mirror coating, mirror glass, etc. The reflecting surface can be a mirror. The first side 833 of the light guide 830 is a plane inclined to the incident surface 831 (i.e., neither horizontal nor vertical), the second side 834 is a curved surface, and the third side 835 is a plane parallel to the incident surface 831 (or perpendicular to the exit surface 832) (i.e., the third side 835 is a horizontal surface). Among them, the first side 833 is the surface of the bent portion 836 of the light guide 830; the second side 835 and the third side 835 both intersect with the exit surface 832, but the second side 835 and the third side 835 do not intersect. The second side 834 can be a convex curved surface or a concave curved surface.Figure 11 The second side surface 834 shown is a convex curved surface. The tangent plane at any position on the second side surface 834 is inclined to the exit surface 832. As mentioned above, curved reflecting surfaces differ from planar reflecting surfaces, including differences in the propagation direction of reflected light and differences in light mixing effects. Furthermore, because the different light beams reflected by the second side surface 834 have different propagation directions, they can undergo different numbers of reflections. That is, some beams are more likely to undergo multiple reflections, while others are less likely to undergo multiple reflections or have relatively fewer reflections. The light mixing effect of a light guide with a third side surface that is inclined or curved is different from... Figure 11 The light guide shown is similar to the 830.

[0081] Figure 11 The diagram shows a schematic of a colorful display component provided in this application. The colorful display component 900 includes a light-emitting unit array 910, a light guide 930, and a support 920. The light-emitting unit array 910 includes light-emitting units with different emitting colors. The support 920 is used to support and fix the light-emitting unit array 910 and the light guide 930, and the support 920 includes a cavity. The light emitted by the light-emitting unit array 910 passes through the cavity and illuminates the incident surface 931 of the light guide 930. After multiple reflections on the side surface of the light guide 930, the light is emitted from the exit surface 932 of the light guide 930. To achieve reflection of light on the side surface of the light guide 930, a reflective structure can be provided close to part or all of the side surface of the light guide 930. Figure 12 (Not shown), the reflecting surface of the reflecting structure for reflecting light is in close contact with the side of the light guide 930. The reflecting structure can be, for example, a mirror coating, mirror glass, etc. The reflecting surface can be a mirror. The first side 933 of the light guide 930 is a plane inclined to the incident surface 931 (i.e., neither horizontal nor vertical), the second side 934 is a plane parallel to the incident surface 931 (or perpendicular to the exit surface 932) (i.e., the second side 934 is a horizontal plane), and the third side 935 is a curved surface. The first side 933 is the surface of the bent portion 936 of the light guide 930; both the second and third side surfaces 935 intersect with the exit surface 932, but the second and third side surfaces 935 do not intersect. The third side surface 935 can be a convex or concave curved surface. Figure 12The third side surface 935 shown is a convex curved surface. The tangent plane at any position on the third side surface 935 is inclined to the exit surface 932. As mentioned above, the differences between curved and planar reflective surfaces include differences in the propagation direction of reflected light and differences in light mixing effects. Furthermore, because different light beams reflected by the third side surface 935 have different propagation directions, they can undergo different numbers of reflections. This means that some beams are more likely to undergo multiple reflections, while others are less likely to undergo multiple reflections or have relatively fewer reflections. In addition, since most of the light illuminating the third side surface 935 is reflected by the second side surface 934, and some light reflected by the second side surface 934 may not be reflected to the third side surface 935, when the tilt angle of the third side surface 935 is large, making the third side surface 935 curved can reduce the overall size of the light guide 930.

The colorful display component 1000 includes a light-emitting unit array 1010, a light guide 1030, and a support 1020. The light-emitting unit array 1010 includes light-emitting units with different emitting colors. The support 1020 supports and fixes the light-emitting unit array 1010 and the light guide 1030, and includes a cavity. Light emitted from the light-emitting unit array 1010 passes through this cavity and illuminates the incident surface 1031 of the light guide 1030. After multiple reflections on the side surface of the light guide 1030, the light exits from the exit surface 1032 of the light guide 1030. To achieve reflection of light on the side surface of the light guide 1030, a reflective structure can be provided close to part or all of the side surface of the light guide 1030.

Among them, the first side 1033 is the surface of the bent portion 1036 of the light guide 1030, and the tangent plane at any position on the first side 1033 is inclined to the incident surface 1031; the second side 1035 and the third side 1035 both intersect with the exit surface 1032, but the second side 1035 and the third side 1035 do not intersect. Figure 13 Compared to the light guide 430 shown, the first side surface 1033 of the light guide 1030 is set as a curved surface, which allows the light beam to pass through... Figure 13 The light guide 1030 shown undergoes more refractions, thus reducing the overall size of the light guide 1030 while keeping the number of reflections constant.

[0083] Figure 12 The diagram shows a schematic of a color display component provided in this application. The color display component 1100 includes a light-emitting unit array 1110, a light guide 1130, and a support 1120.

The support 1120 is used to support and fix the light-emitting unit array 1110 and the light guide 1130, and the support 1120 includes a cavity. Light emitted from the light-emitting unit array 1110 passes through the cavity and illuminates the incident surface 1131 of the light guide 1130. After multiple reflections on the side surface of the light guide 1130, it is emitted from the exit surface 1132 of the light guide 1130. To achieve reflection of light on the side surface of the light guide 1130, a reflective structure can be provided close to part or all of the side surface of the light guide 1130. Figure 13 (Not shown), the reflective surface of the reflective structure used to reflect light is in close contact with the side of the light guide 1130. The reflective structure can be, for example, a mirror coating, mirror glass, etc. The reflective surface can be a mirror. The first side 1133 of the light guide 1130 is a convex curved surface, the second side 1134 is a plane inclined to the incident surface 1131 (i.e., neither horizontal nor vertical), and the third side 1135 is a plane parallel to the incident surface 1131 (or perpendicular to the exit surface 1132) (i.e., the third side 1135 is a horizontal plane).

Figure 13 As shown, with the same number of reflections, the propagation distance from the incident surface 1131 of the light guide 1130 to the exit surface 1132 of the light guide 1130 is significantly shorter than that from the incident surface 1131 to the exit surface 1132 of the light guide 1130. Figure 14 The light guide 1030 shown has a propagation distance from its incident surface 1031 to its exit surface 1032. Therefore, the overall size of the light guide 1030 can be reduced. Furthermore, because the light... Figure 14 The propagation distance within the light guide 1130 shown is relatively short, so light rays from different propagation directions can mix.

The colorful display component 1200 includes a light-emitting unit array 1210, a light guide 1230, and a support 1220. The light-emitting unit array 1210 includes light-emitting units with different emitting colors. The support 1220 supports and fixes the light-emitting unit array 1210 and the light guide 1230, and includes a cavity. Light emitted from the light-emitting unit array 1210 passes through this cavity and illuminates the incident surface 1231 of the light guide 1230. After multiple reflections on the side surface of the light guide 1230, the light exits from the exit surface 1232 of the light guide 1230. To achieve reflection of light on the side surface of the light guide 1230, a reflective structure can be provided close to part or all of the side surface of the light guide 1230. Figure 14 (Not shown), the reflective surface of the reflective structure used to reflect light is in close contact with the side of the light guide 1230. The reflective structure can be, for example, a mirror coating, mirror glass, etc. The reflective surface can be a mirror. The first side 1233 of the light guide 1230 is a convex curved surface, the second side 1234 is a plane parallel to the incident surface 1231 (or perpendicular to the exit surface 1232) (i.e., the second side 1234 is a horizontal plane), and the third side 1235 is a plane inclined to the incident surface 1231.

In contrast, [the light]... Figure 14 Compared to the light guide 1130 shown, Figure 12 The light propagating within the light guide 1130 shown is more prone to multiple reflections, resulting in better light mixing and lower light intensity. In other words, due to the arrangement of the second side 1234 and the third side 1235, Figure 13 The light guide 1230 shown has a light mixing effect and light intensity that are both between [specific ranges]. Figure 14 The light guide 1030 shown Figure 15 Between the light guides 1130 shown, therefore, Figure 15 The light guide 1230 shown can more easily balance light mixing effect and light guiding intensity. Furthermore, if it is desired to further increase the probability of light reflection within the light guide, both the second and third sides can be set as inclined surfaces, such as... Figure 16As shown. The light-mixing effect of a light guide with a curved first side, an inclined second side, and a curved third side is... Figure 16 The light guide shown is similar to the 1330.

[0085] Figure 16 The diagram shows a schematic of a colorful display component provided in this application. The colorful display component 1400 includes a light-emitting unit array 1410, a light guide 1430, and a support 1420. The light-emitting unit array 1410 includes light-emitting units with different emitting colors. The support 1420 is used to support and fix the light-emitting unit array 1410 and the light guide 1430, and the support 1420 includes a cavity. The light emitted by the light-emitting unit array 1410 passes through the cavity and illuminates the incident surface 1431 of the light guide 1430. After multiple reflections on the side of the light guide 1430, the light is emitted from the exit surface 1432 of the light guide 1430. To achieve reflection of light on the side of the light guide 1430, a reflective structure can be provided close to part or all of the side of the light guide 1430. Figure 11 (Not shown), the reflecting surface of the reflecting structure used to reflect light is in close contact with the side of the light guide 1430. The reflecting structure can be, for example, a mirror coating, mirror glass, etc. The reflecting surface can be a mirror. The first side 1433 of the light guide 1430 is a convex curved surface, the second side 1434 is a curved surface, and the third side 1435 is a plane parallel to the incident surface 1431 (or perpendicular to the exit surface 1432) (i.e., the third side 1435 is a horizontal plane). The first side 1433 is the surface of the bent portion 1436 of the light guide 1430, and the tangent plane at any position on the first side 1433 is inclined to the incident surface 1431; the second side 1435 and the third side 1435 both intersect with the exit surface 1432, but the second side 1435 and the third side 1435 do not intersect. The third side 1435 can be a convex curved surface or a concave curved surface. Figure 16 The third side surface 1435 shown is a convex curved surface. The tangent plane at any position on the third side surface 1435 is inclined to the exit surface 1432. As mentioned above, curved reflecting surfaces differ from planar reflecting surfaces, including differences in the propagation direction of reflected light and differences in light mixing effects. Furthermore, because the different light beams reflected by the second side surface 1434 have different propagation directions, the different light beams reflected by the second side surface 1434 can undergo different numbers of reflections; that is, some light beams can be more easily reflected multiple times, while other light beams are less likely to undergo multiple reflections or have relatively fewer reflections. Figure 16 Compared to the light guide 930 shown, in Figure 17 The light beams propagating within the light guide 1430 shown can undergo more thorough mixing because mixing can occur between different light beams propagating in different directions within the light guide 1430. The light mixing effect of a light guide with a third side that is inclined or curved is... Figure 17The light guide shown is similar to the 1430.

The first side 1533 of the light guide 1530 is a convex curved surface, the second side 1534 is a plane parallel to the incident surface 1531 (or perpendicular to the exit surface 1532) (i.e., the second side 1534 is a horizontal plane), and the third side 1535 is a curved surface. The first side 1533 is the surface of the bent portion 1536 of the light guide 1530, and the tangent plane at any position on the first side 1533 is inclined to the incident surface 1531; the second side 1535 and the third side 1535 both intersect with the exit surface 1532, but the second side 1535 and the third side 1535 do not intersect. The third side 1535 can be a convex curved surface or a concave curved surface. Figure 14 The third side surface 1535 shown is a convex curved surface. The tangent plane at any position on the third side surface 1535 is inclined to the exit surface 1532. The differences between curved and planar reflecting surfaces were mentioned above, including differences in the direction of reflected light propagation and in light mixing effects. Figure 17 The light guide 1030 shown Figure 18 Compared to the light guide 1230 shown, in Figure 19 The light beams propagating within the light guide 1530 can undergo more thorough mixing because different light beams propagating in different directions can mix within the light guide 1530. Furthermore, since the different light beams reflected by the third side 1535 have different propagation directions, they can undergo different numbers of reflections. This means that some light beams are more likely to undergo multiple reflections, while other light beams are less likely to undergo multiple reflections or have relatively fewer reflections.

[0087] Therefore, it can be seen that the influence of the first, second, and third sides on the number of reflections of light within the light guide gradually decreases from high to low. Inclined surfaces, horizontal surfaces, and curved surfaces also affect the way light propagates within the light guide.

[0088] Figure 18 The diagram shown is a structural schematic of a colorful display component 1600 provided in an embodiment of this application. Figure 19 The image shown is an exploded view of the colorful display component 1600. The colorful display component 1600 includes a light-emitting unit array 1610, a light guide 1630, and a support 1620. The light-emitting unit array 1610 includes light-emitting units with different emitting colors. The support 1620 supports and fixes the light-emitting unit array 1610 and the light guide 1630, and includes a cavity. Light emitted from the light-emitting unit array 1610 passes through this cavity and illuminates the incident surface 1631 of the light guide 1630. After multiple reflections on the side of the light guide 1630, the light exits from the exit surface 1632 of the light guide 1630. To achieve reflection of light on the side of the light guide 1630, a reflective structure can be provided close to part or all of the side of the light guide 1630. Figure 19 , Figure 20 (Not shown), the reflective surface of the reflective structure for reflecting light is in close contact with the side of the light guide 1630. The reflective structure can be, for example, a mirror coating, mirror glass, etc. The reflective surface can be a mirror. The support 1620 includes ribs located on the inner wall of the cavity of the support 1620 for supporting the light guide 1630. Figure 20 The rib 1660 shown is a frame-shaped rib, meaning it comprises four ribs. Adjacent ribs are connected together and perpendicular to each other, while non-adjacent ribs are parallel to each other. This application does not limit the shape of the ribs. The bracket 1620 and the light guide 1630 are fixed with screws. The screws are located on the ribs of the bracket 1620, and their positions are outside the illumination area on the light guide 1630. In this application, the illumination area refers to the area illuminated by all or most of the light emitted by the light-emitting unit array 1610. On one hand, the screws are located within the cavity of the bracket, preventing users from observing unnecessary components on the exposed area of ​​the electronic device. On the other hand, since the screws are located outside the illumination area of ​​the light guide, they do not affect the glare effect of the display component.

[0089] Optionally, the color display component may also include a light-diffusing sheet disposed within the cavity of the bracket and located between the light-emitting unit array and the incident surface of the light guide, wherein light emitted by the light-emitting unit array passes through the light-diffusing sheet and enters the light guide.

[0090] like Figure 20As shown, the light uniformity sheet 1850 is arranged on one side of the incident surface 1831 of the light guide 1830 facing the light emitting unit array 1810. The light uniformity sheet 1850 can make the light more uniform, which helps to improve the glare effect. It should be understood that, Figure 6 The light guide 1830 shown is only an example. The light uniformity sheet can also be used with light guides other than Figure 20 the light guide shown in FIGS. 9-17, for example, with Figure 19 , 7 the light guide shown in FIGS. 9-17.

[0091] In one example, the light uniformity sheet 1850 can be fixed on the incident surface 1831 of the light guide 1830 using optical glue, as shown. Figure 24

[0092] In one example, the light uniformity sheet can be abutted against the ribs on the inner wall of the bracket. In addition to the box-shaped ribs shown, Figures 21 to 23 the ribs on the inner wall of the bracket can be two ribs parallel to each other or perpendicular to each other. Among them, Figure 21 the first rib 2263 and the second rib 2264 shown are two parallel ribs. The shape of the ribs is not limited in the present application.

[0093] The ribs on the inner wall of the cavity can not only fix the position of the light uniformity sheet and / or the light guide to ensure installation accuracy, but also prevent light leakage. As shown, Figure 22 the structure diagram of installing the light uniformity sheet on the bracket containing the ribs.

[0094] As shown, Figure 23 the light uniformity sheet 1950 is abutted against the ribs away from the light emitting unit array 1910, and the light guide 1930 is abutted against the bracket 1920 by abutting against the light uniformity sheet 1950.

[0095] As shown, Figures 21 to 23 the light uniformity sheet 2050 is abutted against the ribs close to the light emitting unit array 2010, and the light guide 2030 is abutted against the ribs away from the light emitting unit array 2010. The gap between the light uniformity sheet 2050 and the light guide 2030 can be filled with optical glue or light uniformity material.

[0096] As shown, Figure 24 the light uniformity sheet 2150 is located between two parallel ribs, and the light guide 2130 is abutted against the ribs away from the light emitting unit array 2110.

[0097] Figure 24 ​The embodiments shown are only to help those skilled in the art better understand the technical solutions of the present application, and are not a limitation on the technical solutions of the present application. Those skilled in the art will think of many improvements and other embodiments of the present application under the guidance of the foregoing description and the related drawings presented. Therefore, it should be understood that the present application is not limited to the specific embodiments disclosed.

[0098] Optionally, the first light-emitting unit is adjacent to the second light-emitting unit, the distance between the center of the first light-emitting unit and the center of the second light-emitting unit is W, and the spacing between the first light-emitting unit and the incident surface of the light guide body or the light uniformizing sheet is H, and the value of H / W is greater than or equal to 0.8.

[0099] The research results show that when the value of H / W is greater than or equal to 0.8, the iridescent display device has better iridescent effect. That is, the closer the arrangement of the light-emitting units, or the longer the propagation distance of the light in the cavity, the better the iridescent effect.

The light guide body 2230 is provided with a guide groove 2265 for preventing the light uniformizing sheet 2250 from being displaced; the light guide body 2230 abuts against the first prism strip 2263 and the second prism strip 2264 of the support 2220 through the light uniformizing sheet 2250. The light emitted by the light-emitting unit array 2210 passes through the cavity and irradiates on the incident surface 2231 of the light guide body 2230, and is emitted from the exit surface 2232 of the light guide body 2230 after multiple reflections on the side surface of the light guide body 2230. In order to realize the reflection of the light on the side surface of the light guide body 2230, a reflection structure can be provided close to part or all of the side surface of the light guide body 2230. ​The reflecting surface of the reflecting structure (not shown) for reflecting light is close to the side surface of the light guide 2230. The reflecting structure can be a mirror coating, a mirror glass, or the like. The reflecting surface can be a mirror. The light emitting unit array 2210 arranged on the cover plate 2221 emits light of different colors, and the light rays sequentially pass through the cavity of the support 2220, the light mixing sheet 2250, and the light guide 2230, and the light of multiple colors is mixed by the cavity of the support 2220, the light mixing sheet 2250, and the light guide 2230, to obtain an attractive sparkling effect.
