Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present application.

The electronic device 100 may be a display, a television, a mobile phone, a tablet computer, an e-reader, a notebook computer, a vehicle-mounted device, or a wearable device. The embodiment shown in fig. 1 is described by taking the electronic device 100 as a display as an example.

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 bezel and a rear cover. The frame is arranged around the periphery of the rear cover. The perimeter of the screen assembly 120 abuts the inner edge of the bezel, which may provide mechanical protection to the screen assembly 120. The screen assembly 120 and the rear cover are respectively installed at two sides of the frame, so that the shell 110 can have a mechanical protection effect on components inside the electronic device, especially components installed between the screen assembly 120 and the rear cover. The user may view the screen assembly 120 to enjoy media assets such as images, videos, and the like. The electronic device 100 may further include a base 130 for fixing the orientation of the electronic device 100, such as for vertically positioning the electronic device 100.

In order to make the electronic device 100 more beautiful and pleasant, a colorful display component may be further disposed on the electronic device 100. The glare display assembly may utilize a light source so that a user may observe the light emitted by the glare display assembly. The glare display assembly may be disposed on the housing 110 or the base 130.

The electronic device 100 also includes a control module. The control module is housed in the electronic apparatus 100. For example, the control module is housed in the housing 110 or in the base 130. The control module may include 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 may communicate with each other over a bus. At least one communication interface is used for receiving and transmitting data. The dazzling display assembly is connected with one of the communication interfaces, so that the control module can start the driving circuit to trigger the light-emitting units in the dazzling display assembly to emit light. The at least one memory is for storing program code. The program codes include codes for controlling the light emitting unit to emit or not to emit light, and codes for controlling the color of emitted light. The at least one processor may be configured to execute the application code described above to implement various lighting states of the glare display assembly. In the present application, "at least one" includes one or more of both cases.

Fig. 2 is a schematic structural diagram of a colorful display assembly disposed on the base 130. Fig. 3 and 4 show exploded views of another type of glare display assembly. The glare display assembly 200 includes a light emitting unit array 210, a light guide 230, and a bracket 220.

The light emitting cell array 210 may include a plurality of light emitting cells. The light emitting unit may be a point light source or a line light source. The light emitting unit may be, for example, a Light Emitting Diode (LED) or an Organic Light Emitting Diode (OLED). The plurality of light emitting units include a first light emitting unit and a second light emitting unit, and a color of light emitted by the first light emitting unit is different from a color of light emitted by the second light emitting unit. For example, the light emitted from the first light emitting unit is red light, and the light emitted from the second light emitting unit is blue light. The control module in the electronic device 100 shown in fig. 1 may be used to control the light emitting state of the light emitting cell array 210, and the light emitting state may include a light emitting time, a light emitting period, a light emitting intensity, a light emitting color, and the like. For example, at a first time, the first light emitting unit emits red light, and the second light emitting unit does not emit light; at the second moment, the light emitted by the first light-emitting unit is red light, and the light emitted by the second light-emitting unit is blue light; at the third moment, the first light-emitting unit does not emit light, and the light emitted by the second light-emitting unit is blue light.

Besides supporting and fixing the light emitting unit array 210 and the light guide 230, the bracket 220 further includes a cavity, through which light emitted from the light emitting unit passes and irradiates the incident surface 231 of the light guide 230. The light emitted from the light emitting unit may directly irradiate the incident surface 231 of the light guide 230 without contacting the cavity, or may first irradiate the inner wall of the cavity, and then irradiate the incident surface 231 of the light guide 230 after being reflected once or more. On one hand, the scattering phenomenon of light enables the light to be mixed even if the light is not in contact with the cavity; on the other hand, light not in contact with the cavity may be mixed with light reflected by the inner wall of the cavity. That is, the light of different colors emitted by the light emitting cell array 210 may be mixed within the cavity. The light emitting unit array 210 may be mounted on an inner wall of the bracket 220 (as shown in fig. 2), so that light emitted from the light emitting unit array 210 can enter the cavity of the bracket 220. Alternatively, the frame 220 may include a cover 221 (as shown in fig. 3), and the light emitting unit array 210 may be installed on a side of the cover 221 facing the cavity, so that light emitted from the light emitting unit array 210 can enter the cavity of the frame 220. The present application does not limit the manner of mounting the light emitting cell array 210. The embodiments shown in fig. 2 and fig. 3 are only for helping those skilled in the art to better understand the technical solution of the present application, and are not intended to limit the technical solution of the present application. Many modifications and other embodiments of the disclosure will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the application is not limited to the specific embodiments disclosed.

The surface of the light guide 230 includes an incident surface 231, an emission surface 232, and a side surface connected between the incident surface 231 and the emission surface 232. The incident surface 231 may be a plane or a curved surface, such as a horizontal surface, a convex curved surface, a concave curved surface, and the like. Here, the incidence plane 231 shown in fig. 3 and 4 is represented by a black solid figure. The exit surface 232 may be a flat surface or a curved surface, such as a vertical surface, a convex curved surface, a concave curved surface, and the like. Here, the exit surface 232 shown in fig. 3 and 4 is represented by a black solid figure. The side surface of the light guide 230 may be a flat surface or a curved surface, and may be, for example, a horizontal surface, an inclined plane, an outer convex surface, or an inner concave surface.

The light is incident on the light guide 230 from the incident surface 231 of the light guide 230, is reflected on the side surface of the light guide 230 a plurality of times, and is then emitted from the emission surface 232 of the light guide 230. The sides where reflection of light can occur are, for example, the first side 233, the second side 234, and the third side 235 as shown in fig. 3, wherein the second side 234 and the third side 235 both intersect the exit surface 232. The sides where reflection of light can occur are, for example, the first side 233, the second side 234, and the third side 235 as shown in fig. 4, wherein the second side 234 and the third side 235 both intersect the exit surface 232. The first side surface 233 shown in fig. 3 and 4 is indicated by a surface filled with oblique lines. The second side 234 shown in fig. 3, 4 is represented by a filled square. The third side 235 shown in fig. 3 and 4 is represented by a surface filled with a lattice.

For clarity of description, the plane and the curved surface in the present application have an interface, that is, the plane or the curved surface in the present application has a certain shape, area and size. As shown in fig. 3, the incident surface 231 and the second side surface 234 are coplanar, and due to the cavity, the light enters the light guide 230 only in the area of the incident surface 231, and the light does not enter the light guide 230 from the area of the second side surface 234. Therefore, the shape, area, and size of the incident surface 231 can be determined from the region where the light enters the light guide 230. Similarly, the shape, area, and size of the exit surface 232 can be determined according to the region where the light exits the light guide 230. The surfaces of the light guide 230 other than the incident surface 231 and the emission surface 232 are side surfaces of the light guide 230.

For clarity of description, the convex direction of the convex curved surface faces the outer side of the light guide 230, and the convex direction of the concave curved surface faces the inner side of the light guide 230.

Optionally, the light guide 230 is bent, a part of the light guide 230 is located inside the cavity, and the other part of the light guide 230 is located outside the cavity.

The light guide 230 is bent in shape, meaning that the light guide 230 may include a first portion 236, a second portion 238, and a bent portion 237 connected between the first portion 236 and the second portion 238, and the first portion 236 and the second portion 238 may not be connected. The light guide 230 shown in fig. 3 is an unfolded light guide, and does not include a bent portion. In addition, in the present application, the light guide body including the bent portion does not mean that the shape of the light guide body is a bent shape. For example, the light guide has a cylindrical shape, and light enters from one end of the cylinder and exits from the other end of the cylinder. The cylinder includes the bent portion, but the first portion and the second portion connected to the bent portion are connected, and therefore, the cylindrical light guide (light is incident from one end of the cylinder and emitted from the other end of the cylinder) does not belong to the bent light guide. The light guide 230 shown in fig. 4 is a bent light guide. Wherein the first portion 236 extends into the cavity of the bracket 220 and the bent portion 237 and the second portion 238 are located outside the cavity of the bracket 220. The first side surface 233 is a surface of the bent portion 237. Compared with a non-bending light guide body, a part of the bending light guide body extends into the cavity, so that the bending light guide body is easier to mount.

The light emitted from the light emitting unit array 210 may travel in a direction perpendicular to the incident surface 231 of the light guide 230, or may not travel in a direction perpendicular to the incident surface 231 of the light guide 230, i.e., the incident angle is greater than 0 °. When the incident angle is not 0 °, the light is refracted when entering the light guide 230. The present application takes the case where light is incident perpendicularly into the light guide 230 as an example. Many modifications and other embodiments of the disclosure will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the application is not limited to the specific embodiments disclosed.

In order to realize the reflection of the light on the side surface of the light guide body, a reflection structure can be arranged close to part or all of the side surface of the light guide body, and a reflection surface for reflecting the light on the reflection structure is close to the side surface of the light guide body. "closely attached 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 smaller than a preset threshold value. In the case where the distance between the reflection surface and the side surface of the light guide body is 0, the position at which the light is reflected may be the side surface of the light guide body. When the distance between the reflection surface and the side surface of the light guide is not 0, the position where the light is actually reflected is located on 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 approximated that the light is reflected on the side surface of the light guide. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The reflective structures may be, for example, the first and second

reflective structures

341 and 342 shown in fig. 5.

On one hand, the light irradiated on the side surface of the light guide body can be reflected for multiple times, the overall propagation direction of the light is changed, the propagation distance of the light is prolonged, and the light is favorably mixed; on the other hand, the light rays can generate light in various different propagation directions after being reflected for multiple times, and the light mixing effect is enhanced. The light of different colours can produce the effect of dazzling light after mixing, and is different from the mixed light effect of white light or single colour light, and it has multiple effects such as flow, breathing, dazzling the color.

The difference between the curved side and the flat side is described below. Two beams of light with the same propagation direction irradiate different positions of the reflecting plane, and two beams of reflected light with the same propagation direction can be obtained. The direction of the tangent plane at any position on the side surface of the curved surface is different, so that two beams of light rays in the same propagation direction irradiate different positions of the reflecting curved surface, and two beams of reflected light in different propagation directions are probably obtained due to the change of the curvature of the curved surface. The light mixing of the plane reflecting surface mainly comes from the scattering principle of light and the reflection of light, and the curved reflecting surface can obtain two beams of reflected light with different propagation directions. Therefore, the light emitted by the curved reflecting surface can increase the light mixing effect under the condition that the reflection times are not changed. The designer of the light guide may design the side surfaces (e.g., 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 a plane or a curved surface, and the size, shape, and orientation of the side surfaces of the light guide with respect to the incident surface or the exit surface, according to the requirement, so that the light rays can propagate in the light guide according to a predetermined propagation manner.

On one hand, the light irradiated on the third side surface can be reflected, and the overall propagation direction of the light is changed; on the other hand, light can scatter in the transmission process, and after the light is reflected by the first side surface, the second side surface and the third side surface, the scattering phenomenon of the light is more obvious, so that the light can be fully mixed. Since light may be reflected multiple times, in some cases, mixing between multiple beams of light that travel in different directions may occur.

The light rays are reflected for many times in the light guide body, so that the scattering phenomenon of the light rays is more obvious, and the light rays can be fully mixed. However, the light is reflected multiple times in the light guide, which reduces the intensity of the light. Therefore, the designer of the light guide can reasonably design factors such as the size and the shape of the reflecting surface of the light guide, the direction relative to the incident surface or the emergent surface and the like according to the requirement of the designer of the light guide, so that the light can be reflected in the light guide for a plurality of times, and the intensity of the light emitted out of the emergent surface of the light guide can not be reduced too much.

The following describes in detail the design points of the bending light guide, taking fig. 6 to 17 as an example. For clarity of description, the embodiments of the present application take the incident surface of the light guide as a horizontal surface and the emitting surface of the light guide as a vertical surface as an example, and the orientation of the side surface of the light guide is briefly described with reference to the incident surface or the emitting surface. The embodiments shown in fig. 6 to 17 are only for helping those skilled in the art to better understand the technical solution of the present application, and are not intended to limit the technical solution of the present application. Many modifications and other embodiments of the disclosure will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings, e.g., the design considerations of a non-bending light guide will suggest themselves to those skilled in the art. Therefore, it is to be understood that the application is not limited to the specific embodiments disclosed.

To reflect light at the side of light guide 430, a reflective structure (not shown in fig. 6) may be disposed adjacent to part or all of the side of light guide 430, and a reflective surface of the reflective structure for reflecting light is adjacent to the side of light guide 430. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface.

The first side surface 433 is a plane inclined to the incident surface 431 (i.e., a non-horizontal plane and a non-vertical plane), and 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., the second side surface 434 and the third side surface 435 are both horizontal planes). Wherein, the first side 433 is the surface of the bent part 436 of the light guide 430; second side 434 and third side 435 both intersect with exit surface 432, and second side 434 does not intersect with third side 435.

The light emitting cell array 510 includes light emitting cells emitting different colors of light. The bracket 520 is used for supporting and fixing the light emitting unit array 510 and the light guide 530, and the bracket 520 includes a cavity through which light emitted from the light emitting unit array 510 passes to irradiate on the incident surface 531 of the light guide 530, and is reflected on the side surface of the light guide 530 for multiple times and then emitted from the exit surface 532 of the light guide 530. To achieve light reflection at the side of light guide 530, a reflective structure (not shown in fig. 7) may be disposed adjacent to part or all of the side of light guide 530, and a reflective surface of the reflective structure for reflecting light is adjacent to the side of light guide 530. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The first side 533 and the second side 534 of the light guide 530 are both planes (i.e., non-horizontal and non-vertical planes) inclined to the incident surface 531, and the third side 535 is a plane parallel to the incident surface 531 (or perpendicular to the exit surface 532) (i.e., the third side 535 is a horizontal plane). Wherein the first side surface 533 is a surface of the bent portion 536 of the light guide 530; the second side 535 and the third side 535 intersect with the exit surface 532, and the second side 535 and the third side 535 do not intersect. Since the inclination angle of second side 434 of light guide 430 shown in fig. 6 is different from that of second side 534 of light guide 530 shown in fig. 7, light rays are more likely to be reflected multiple times in light guide 530 shown in fig. 7 than in light guide 430 shown in fig. 6. As shown in fig. 6, most of the light traveling in light guide 430 fails to be irradiated on third side 435 of light guide 430, whereas most of the light traveling in light guide 530 shown in fig. 7 may be irradiated on third side 535 of light guide 530, even with multiple reflections. Multiple reflections can introduce the effects of enhancing light mixing and reducing light intensity.

Fig. 8 is a schematic structural diagram of a colorful display assembly provided by the present application. The glare display assembly 600 includes a light emitting unit array 610, a light guide 630, and a bracket 620. The light emitting cell array 610 includes light emitting cells emitting different colors of light. The holder 620 is used for supporting and fixing the light emitting unit array 610 and the light guide 630, and the holder 620 includes a cavity through which light emitted from the light emitting unit array 610 passes to irradiate on the incident surface 631 of the light guide 630, and is reflected on the side surface of the light guide 630 multiple times and then exits from the exit surface 632 of the light guide 630. To achieve reflection of light at the sides of light guide 630, a reflective structure (not shown in fig. 8) may be disposed adjacent to some or all of the sides of light guide 630, and a reflective surface of the reflective structure for reflecting light is adjacent to the sides of light guide 630. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The first side surface 633 and the third side surface 635 of the light guide 630 are both inclined planes (i.e., non-horizontal planes and non-vertical planes) to the incident surface 631, and the second side surface 634 is a plane parallel to the incident surface 631 (or perpendicular to the exit surface 632) (i.e., the second side surface 634 is a horizontal plane). Wherein, the first side face 633 is the surface of the bent portion 636 of the light guide 630; the second side surface 635 and the third side surface 635 are intersected with the exit surface 632, and the second side surface 635 and the third side surface 635 are not intersected. Since the inclination angle of the third side 435 of the light guide 430 shown in fig. 6 is different from the inclination angle of the third side 635 of the light guide 630 shown in fig. 8, the light is incident on the light guide 430 shown in fig. 6, compared to the light guide 430 shown in fig. 6

A part of the light rays of the light guide 630 shown in fig. 8 may be irradiated on the third side 635 of the light guide 630, and the other part of the light rays incident on the light guide 630 may not be irradiated on the third side 635 of the light guide 630, so that a part of the light rays reflected by the third side 635 has a good light mixing effect and a low light intensity. Therefore, the light guide 630 shown in fig. 8 can uniformize a small portion of the light propagating inside the light guide 630. In contrast to light guide 530 shown in fig. 7, second side surface 534 of light guide 530 is an inclined surface, and second side surface 634 of light guide 630 is a horizontal surface, so that light is more likely to be reflected multiple times in light guide 530 shown in fig. 7, and light guide 630 shown in fig. 8 is more likely to uniformize a small portion of the light propagating in light guide 630.

Fig. 9 is a schematic structural diagram of a glare display assembly provided in the present application. The glare display assembly 700 includes a light emitting unit array 710, a light guide 730, and a bracket 720. The light emitting cell array 710 includes light emitting cells emitting different colors of light. The holder 720 is used for supporting and fixing the light emitting unit array 710 and the light guide 730, and the holder 720 includes a cavity through which light emitted from the light emitting unit array 710 passes to irradiate on the incident surface 731 of the light guide 730, and is reflected on the side surface of the light guide 730 for multiple times and then emitted from the exit surface 732 of the light guide 730. To reflect light at the side of the light guide 730, a reflecting structure (not shown in fig. 9) may be disposed adjacent to a part or all of the side of the light guide 730, and a reflecting surface of the reflecting structure for reflecting light is adjacent to the side of the light guide 730. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The first side 733, the second side 734, and the third side 735 of the light guide 730 are all planes (i.e., non-horizontal planes and non-vertical planes) inclined to the incident plane 731. The first side 733 is a surface of the bent portion 736 of the light guide 730; second side 735 and third side 735 both intersect exit face 732, and second side 735 and third side 735 do not intersect. Since the second side surface 734 and the third side surface 735 shown in fig. 9 are both inclined surfaces, light rays can be reflected multiple times in the light guide 730, and can be unevenly uniformized (or referred to as partial uniformization), that is, the uniformization effect of a part of the light beams can be different from that of the other light beams. Unlike the light guide 630 shown in fig. 8, since light can be reflected multiple times in the light guide 730 shown in fig. 9, light beams having different homogenization effects can be mixed with each other, and the effect of diversified mixing of light can be achieved. The light mixing effect of the light guide with the curved third side surface is similar to that of the light guide 730 shown in fig. 9.

Fig. 10 is a schematic structural diagram of a glare display assembly provided in the present application. The glare display assembly 800 includes a light emitting unit array 810, a light guide 830, and a bracket 820. The light emitting cell array 810 includes light emitting cells emitting different colors of light. The holder 820 is used for supporting and fixing the light emitting unit array 810 and the light guide body 830, and the holder 820 includes a cavity through which light emitted from the light emitting unit array 810 passes to irradiate on the incident surface 831 of the light guide body 830, and is reflected on the side surface of the light guide body 830 for multiple times and then emitted from the exit surface 832 of the light guide body 830. To achieve the reflection of the light on the side of the light guide 830, a reflection structure (not shown in fig. 10) may be disposed adjacent to part or all of the side of the light guide 830, and a reflection surface of the reflection structure for reflecting the light is adjacent to the side of the light guide 830. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The first side 833 of the light guide 830 is a plane inclined to the incident surface 831 (i.e., a non-horizontal plane and a non-vertical plane), the second side 834 is a curved plane, 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 plane). First side 833 is the surface of bent portion 836 of light guide 830; the second side 835 and the third side 835 intersect with the exit surface 832, and the second side 835 does not intersect with the third side 835. The second side 834 may be a convex curved surface or a concave curved surface, and the second side 834 shown in fig. 10 is a convex curved surface. A tangent plane anywhere on the second side 834 is oblique to the exit face 832. The differences between the curved reflective surface and the flat reflective surface, including the difference in the propagation direction of the reflected light and the difference in the light mixing effect, are mentioned above. In addition, because the propagation directions of different light beams reflected by the second side surface 834 are different, different light beams reflected by the second side surface 834 can be reflected for different times, that is, a part of light beams can be reflected for multiple times more easily, and other parts of light beams can be reflected for multiple times more difficultly or for relatively less times. And the light mixing effect of the light guide body with the inclined surface or the curved surface on the third side surface is similar to that of the light guide body 830 shown in fig. 10.

Fig. 11 is a schematic structural diagram of a glare display assembly provided in the present application. The glare display assembly 900 includes a light emitting unit array 910, a light guide 930, and a bracket 920. The light emitting cell array 910 includes light emitting cells emitting different colors of light. The holder 920 is used for supporting and fixing the light emitting unit array 910 and the light guide 930, and the holder 920 includes a cavity through which light emitted from the light emitting unit array 910 passes to irradiate on the incident surface 931 of the light guide 930, and is reflected on the side surface of the light guide 930 for multiple times and then emitted from the emitting surface 932 of the light guide 930. To achieve the reflection of light at the side surfaces of the light guide 930, a reflecting structure (not shown in fig. 11) may be disposed adjacent to part or all of the side surfaces of the light guide 930, and a reflecting surface of the reflecting structure for reflecting light is adjacent to the side surfaces of the light guide 930. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The first side 933 of the light guide 930 is a plane (i.e., non-horizontal and non-vertical) inclined to the incident surface 931, the second side 934 is a plane (i.e., the second side 934 is a horizontal plane) parallel to the incident surface 931 (or perpendicular to the exit surface 932), and the third side 935 is a curved surface. Wherein, the first side 933 is a surface of the bent portion 936 of the light guide 930; the second side surface 935 and the third side surface 935 both intersect the exit surface 932, and the second side surface 935 does not intersect the third side surface 935. The third side surface 935 may be a convex curved surface or a concave curved surface, and the third side surface 935 shown in fig. 11 is a convex curved surface. A tangential plane at any location on the third side surface 935 is inclined to the exit surface 932. The differences between the curved reflective surface and the flat reflective surface, including the difference in the propagation direction of the reflected light and the difference in the light mixing effect, are mentioned above. In addition, different beams reflected by the third side 935 may have different times of reflection due to different propagation directions of the different beams reflected by the third side 935, that is, a part of the beams may be more easily reflected for multiple times, and other parts of the beams may be more difficult to transmit for multiple times or the number of reflections may be relatively small. In addition, since most of the light irradiated on the third side surface 935 is reflected by the second side surface 934, and part of the light reflected by the second side surface 934 may not be reflected to the third side surface 935, when the inclination angle of the third side surface 935 is large, the overall size of the light guide 930 may be reduced by providing the third side surface 935 as a curved surface.

Fig. 12 is a schematic structural diagram of a glare display assembly provided in the present application. The glare display assembly 1000 includes a light emitting unit array 1010, a light guide 1030, and a bracket 1020. The light emitting cell array 1010 includes light emitting cells emitting different colors of light. The holder 1020 is used for supporting and fixing the light emitting unit array 1010 and the light guide 1030, and the holder 1020 includes a cavity through which light emitted from the light emitting unit array 1010 passes to irradiate on the incident surface 1031 of the light guide 1030, and is reflected on the side surface of the light guide 1030 for multiple times and then emitted from the emitting surface 1032 of the light guide 1030. To achieve light reflection at the sides of light guide 1030, a reflective structure (not shown in fig. 12) may be disposed adjacent to some or all of the sides of light guide 1030, with a reflective surface of the reflective structure for reflecting light adjacent to the sides of light guide 1030. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The first side 1033 of the light guide 1030 is a convex curved surface, and the second side 1034 and the third side 1035 are both planes parallel to the incident surface 1031 (or perpendicular to the exit surface 1032) (i.e., the second side 1034 and the third side 1035 are horizontal planes). Wherein, the first side 1033 is a surface of the bent portion 1036 of the light guide 1030, and a tangential plane at any position on the first side 1033 is inclined to the incident surface 1031; second side 1035 and third side 1035 both intersect exit face 1032, and second side 1035 and third side 1035 do not intersect. Compared to the light guide body 430 shown in fig. 6, the first side 1033 of the light guide body 1030 is provided as a curved surface, and the light flux can be refracted more times in the light guide body 1030 shown in fig. 12, and therefore the overall secondary size of the light guide body 1030 can be reduced with a fixed number of reflections.

Fig. 13 is a schematic structural diagram of a glare display assembly provided in the present application. The glare display assembly 1100 includes a light emitting unit array 1110, a light guide 1130, and a bracket 1120. The light emitting cell array 1110 includes light emitting cells emitting different colors of light. The bracket 1120 is used for supporting and fixing the light emitting unit array 1110 and the light guide 1130, and the bracket 1120 includes a cavity through which light emitted from the light emitting unit array 1110 passes to irradiate on the incident surface 1131 of the light guide 1130, and is reflected on the side surface of the light guide 1130 for multiple times and then emitted from the exit surface 1132 of the light guide 1130. To achieve light reflection at the side surfaces of light guide 1130, a reflective structure (not shown in fig. 13) may be disposed adjacent to part or all of the side surfaces of light guide 1130, and a reflective surface of the reflective structure for reflecting light is adjacent to the side surfaces of light guide 1130. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The first side surface 1133 of the light guide 1130 is a convex curved surface, the second side surface 1134 is a plane (i.e., a non-horizontal plane and a non-vertical plane) inclined to the incident surface 1131, and the third side surface 1135 is a plane (i.e., the third side surface 1135 is a horizontal plane) parallel to the incident surface 1131 (or perpendicular to the exit surface 1132). The first side surface 1133 is a surface of the bent portion 1136 of the light guide 1130, and a tangent plane at any position on the first side surface 1133 is inclined to the incident surface 1131; second side 1135 and third side 1135 both intersect exit surface 1132, and second side 1135 and third side 1135 do not intersect. Since the inclination angle of the second side surface 1034 of the light guide 1030 shown in fig. 12 is different from the inclination angle of the second side surface 1134 of the light guide 1130 shown in fig. 13, light rays are more likely to be reflected multiple times in the light guide 1130 shown in fig. 13 than the light guide 1030 shown in fig. 12. As shown in fig. 13, in the case where the number of reflections is the same, the propagation distance from the incident surface 1131 of the light guide 1130 to the emission surface 1132 of the light guide 1130 is significantly shorter than the propagation distance from the incident surface 1031 of the light guide 1030 to the emission surface 1032 of the light guide 1030 shown in fig. 12. Accordingly, the overall size of light guide 1130 may be reduced. Also, since the light travels a short distance in the light guide 1130 shown in fig. 13, light rays of different traveling directions may be mixed.

Fig. 14 is a schematic structural diagram of a glare display assembly provided in the present application. The glare display assembly 1200 includes a light emitting unit array 1210, a light guide 1230, and a bracket 1220. The light emitting cell array 1210 includes light emitting cells emitting different colors of light. The holder 1220 is used for supporting and fixing the light emitting unit array 1210 and the light guide 1230, and the holder 1220 includes a cavity through which light emitted from the light emitting unit array 1210 passes to irradiate on the incident surface 1231 of the light guide 1230, and is reflected on the side surface of the light guide 1230 for multiple times and then emitted from the emitting surface 1232 of the light guide 1230. To achieve reflection of light rays at the sides of the light guide 1230, a reflective structure (not shown in fig. 14) may be disposed adjacent to some or all of the sides of the light guide 1230, and a reflective surface of the reflective structure for reflecting light rays is adjacent to the sides of the light guide 1230. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. 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. Wherein, the first side surface 1233 is a surface of the bent portion 1236 of the light guide 1230, and a tangential plane at any position on the first side surface 1233 is inclined to the incident surface 1231; second side 1235 and third side 1235 both intersect exit face 1232, and second side 1235 and third side 1235 do not intersect. Since the inclination angle of the third side 1035 of the light guide 1030 shown in fig. 12 is different from the inclination angle of the third side 1235 of the light guide 1230 shown in fig. 14, the light propagating through the light guide 1230 shown in fig. 14 is more likely to be reflected multiple times than the light guide 1030 shown in fig. 12, and thus the light mixing effect is better and the light intensity is lower. On the other hand, the light ray propagating through the light guide 1130 shown in fig. 13 is more likely to be reflected multiple times than the light guide 1130 shown in fig. 13, and thus the light mixing effect is better and the light ray intensity is lower. In other words, due to the arrangement of the second side 1234 and the third side 1235, the light mixing effect and the light intensity of the light guide 1230 shown in fig. 14 are both between the light guide 1030 shown in fig. 12 and the light guide 1130 shown in fig. 13, and thus the light guide 1230 shown in fig. 14 can more easily achieve both the light mixing effect and the light guide intensity. In addition, if it is desired to further increase the probability of light reflection in the light guide, both the second side surface and the third side surface may be provided with inclined surfaces, as shown in fig. 15. The light mixing effect of the light guide with the curved first side surface, the inclined second side surface and the curved third side surface is similar to that of the light guide 1330 shown in fig. 15.

Fig. 16 is a schematic structural diagram of a glare display assembly provided in the present application. The glare display assembly 1400 includes a light emitting unit array 1410, a light guide 1430, and a support 1420. The light emitting cell array 1410 includes light emitting cells emitting light of different 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 through which light emitted from the light emitting unit array 1410 passes to irradiate on the incident surface 1431 of the light guide 1430, and is reflected on the side surface of the light guide 1430 for multiple times and then exits from the exit surface 1432 of the light guide 1430. To achieve light reflection at the sides of the light guide 1430, a reflective structure (not shown in fig. 16) may be provided adjacent to some or all of the sides of the light guide 1430, with a reflective surface on the reflective structure for reflecting light adjacent to the sides of the light guide 1430. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The first side 1433 of the light guide 1430 is an outward 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). Wherein, the first side surface 1433 is a surface of the bending portion 1436 of the light guide 1430, and a tangential plane at any position on the first side surface 1433 is inclined to the incident surface 1431; the second side 1435 and the third side 1435 both intersect the exit face 1432, and the second side 1435 and the third side 1435 do not intersect. The third side 1435 may be a convex curved surface or a concave curved surface, and the third side 1435 shown in fig. 16 is a convex curved surface. A tangent plane at any position on the third side surface 1435 is inclined to the exit surface 1432. The differences between the curved reflective surface and the flat reflective surface, including the difference in the propagation direction of the reflected light and the difference in the light mixing effect, are mentioned above. In addition, 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 be reflected for different times, i.e., a part of the light beams can be reflected for multiple times more easily, and the other part of the light beams can be reflected for multiple times more difficultly or for relatively fewer times. The light beams propagating within the light guide 1430 shown in fig. 16 may be more thoroughly mixed than the light guide 930 shown in fig. 11, because mixing may occur between different light beams propagating in different propagation directions within the light guide 1430. The light mixing effect of the light guide with the inclined or curved third side surface is similar to that of the light guide 1430 shown in fig. 16.

Fig. 17 is a schematic structural diagram of a glare display assembly provided in the present application. The glare display assembly 1500 includes a light emitting unit array 1510, a light guide 1530, and a bracket 1520. The light emitting cell array 1510 includes light emitting cells different in emission color. The holder 1520 is used to support and fix the light emitting unit array 1510 and the light guide 1530, and the holder 1520 includes a cavity through which light emitted from the light emitting unit array 1510 passes to irradiate on the incident surface 1531 of the light guide 1530, and then, the light is reflected on the side surface of the light guide 1530 multiple times and then exits from the exit surface 1532 of the light guide 1530. To reflect light on the side surfaces of light guide 1530, a reflecting structure (not shown in fig. 17) may be provided in close contact with part or all of the side surfaces of light guide 1530, and a reflecting surface for reflecting light on the reflecting structure is in close contact with the side surfaces of light guide 1530. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The light guide 1530 has a first side 1533 with a convex curved surface, a second side 1534 with a flat surface parallel to the incident surface 1531 (or perpendicular to the exit surface 1532) (i.e., the second side 1534 is a horizontal surface), and a third side 1535 with a curved surface. Wherein, the first side 1533 is a surface of the bent portion 1536 of the light guide 1530, and a tangential plane at any position on the first side 1533 is inclined to the incident surface 1531; second side 1535 and third side 1535 both intersect exit face 1532, and second side 1535 and third side 1535 do not intersect. The third side 1535 may be a convex curved surface or a concave curved surface, and the third side 1535 shown in fig. 17 is a convex curved surface. The tangential plane at any position on the third side 1535 is inclined to the exit face 1532. The differences between the curved reflective surface and the flat reflective surface, including the difference in the propagation direction of the reflected light and the difference in the light mixing effect, are mentioned above. The light beams propagating in the light guide 1530 shown in fig. 17 can be mixed more sufficiently than the light guide 1030 shown in fig. 12 and the light guide 1230 shown in fig. 14, because mixing can occur between different light beams propagating in different propagation directions in the light guide 1530. In addition, since the different light beams reflected by the third side 1535 have different propagation directions, the different light beams reflected by the third side 1535 may be reflected for different times, that is, a part of the light beams may be reflected for multiple times more easily, and the other part of the light beams may be more difficult to transmit for multiple times or the number of times of reflection is relatively small.

Therefore, it can be seen that the influence of the first side surface, the second side surface and the third side surface on the number of times of reflection of the light rays in the light guide body is gradually reduced from high to low. The inclined surface, the horizontal surface, the curved surface, etc. also affect the propagation of light in the light guide body.

Fig. 18 is a schematic structural diagram of a colorful display assembly 1600 provided in an embodiment of the present application. FIG. 19 shows an exploded view of the glare display assembly 1600. The glare display assembly 1600 includes a light emitting unit array 1610, a light guide 1630, and a bracket 1620. The light emitting cell array 1610 includes light emitting cells emitting different colors of light. The bracket 1620 is used for supporting and fixing the light emitting unit array 1610 and the light guide body 1630, and the bracket 1620 includes a cavity through which light emitted from the light emitting unit array 1610 passes to irradiate on the incident surface 1631 of the light guide body 1630, and is reflected on the side surface of the light guide body 1630 for multiple times to be emitted from the emitting surface 1632 of the light guide body 1630. To reflect light at the side of light guide 1630, a reflective structure (not shown in fig. 18 and 19) may be disposed adjacent to part or all of the side of light guide 1630, and a reflective surface of the reflective structure for reflecting light is adjacent to the side of light guide 1630. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The bracket 1620 includes ribs on the inner wall of the cavity of the bracket 1620 for supporting the light guide 1630. The rib 1660 shown in fig. 19 is a frame-shaped rib, that is, the rib 1660 comprises 4 ribs, two adjacent ribs are connected together and perpendicular to each other, and two non-adjacent ribs are parallel to each other. The shape of the ribs is not limited in this application. The bracket 1620 and the light guide 1630 are fixed by screws, the screws are disposed on the ribs of the bracket 1620, and the positions of the screws are located outside the irradiation area on the light guide 1630. In the present application, the irradiation region refers to a region irradiated with all or most of the light emitted from the light emitting unit array 1610. On the one hand, the screw is arranged in the cavity of the bracket, so that a user is prevented from observing that redundant components are arranged in an exposed area of the electronic equipment. On the other hand, the screw is arranged at a position outside the irradiation area of the light guide body, so that the screw does not affect the glare effect of the glare display assembly.

Optionally, the dazzle color display assembly may further include a light uniformizing sheet, the light uniformizing sheet is disposed in the cavity of the bracket and located between the light emitting unit array and the incident surface of the light guide body, and light emitted by the light emitting unit array passes through the light uniformizing sheet and is incident into the light guide body.

As shown in fig. 20, a light equalizing sheet 1850 is disposed on the side of the incident surface 1831 of the light guide 1830 facing the light emitting unit array 1810. Because the uniform light piece 1850 can make light more even, help promoting dazzling light effect. It should be understood that the light guide 1830 shown in fig. 20 is merely an example, and the light equalizing sheet may be used with other types of light guides other than the light guide 1830 shown in fig. 20, such as the light guides shown in fig. 6, 7, and 9-17.

In one example, the light equalizing sheet 1850 may be fixed on the incident surface 1831 of the light guide 1830 using an optical glue, as shown in fig. 20.

In one example, the light homogenizing sheet can be abutted against ribs on the inner wall of the bracket. In addition to the frame-shaped ribs shown in fig. 19, the ribs of the inner wall of the bracket may be 2 ribs parallel or perpendicular to each other. In fig. 24, the first rib 2263 and the second rib 2264 are 2 parallel ribs. The shape of the ribs is not limited in this application.

Set up the rib at the cavity inner wall, except can fix the position of even light piece and/or light conductor to guarantee the installation accuracy, can also prevent the light leak. Fig. 21 to 23 are schematic structural views illustrating the mounting of the light uniformizing sheet on the support including the ribs.

As shown in fig. 21, the light equalizing sheet 1950 abuts on the side of the rib away from the light emitting unit array 1910, and the light guide body 1930 abuts on the bracket 1920 by abutting on the light equalizing sheet 1950.

As shown in fig. 22, the light equalizing sheet 2050 abuts on the side of the rib close to the light emitting unit array 2010, and the light guide 2030 abuts on the side of the rib away from the light emitting unit array 2010. The gap between the light equalizing sheet 2050 and the light guide 2030 may be filled with an optical glue or a light equalizing material.

As shown in fig. 23, the light equalizing sheet 2150 is disposed between two parallel ribs, and the light guide 2130 abuts against a side of the rib away from the light emitting unit array 2110.

Light emitted from the light emitting unit array 2210 passes through the cavity to be irradiated onto the incident surface 2231 of the light guide 2230, and is reflected multiple times on the side surface of the light guide 2230 and then emitted from the exit surface 2232 of the light guide 2230. To reflect the light on the side of the light guide 2230, a reflective structure (not shown in fig. 24) may be disposed adjacent to a part or all of the side of the light guide 2230, and a reflective surface of the reflective structure for reflecting the light is adjacent to the side of the light guide 2230. The reflective structure may be, for example, a specular coating, a specular glass, or the like. The reflective surface may be a mirror surface. The light emitting unit arrays 2210 arranged on the cover plate 2221 emit light of different colors, the light sequentially passes through the cavity of the holder 2220, the light equalizing sheet 2250 and the light guide 2230, and the light of multiple colors is mixed through the cavity of the holder 2220, the light equalizing sheet 2250 and the light guide 2230, so as to obtain an attractive glare effect.
