In practical application, the leaded light module can be connected with the display screen in products such as smart mobile phone, on-vehicle display, medical display appearance, industrial control equipment display, household electrical appliances display and other electronic displays. For example, the light guide module can be bonded on the surface of a display screen of a smart phone, a vehicle-mounted display, a medical display, an industrial control equipment display, a household appliance display or other electronic displays in a bonding mode.

In an embodiment of the present disclosure, the light guide module may include: frame, light guide plate. Here, the frame body may include: the frame body surrounds to form the accommodating space, the accommodating space can be of a hollow structure, and the light guide plate is located in the accommodating space, so that the accommodating space of the frame body can be utilized to limit the position of the light guide plate, and the light guide plate is prevented from displacing.

In some embodiments, the frame body may be a frame structure made of a hard material. For example, the frame body may be a frame structure made of metal. For another example, the frame body may also be a frame structure made of a novel metal material, and the material for making the frame body may be selected according to actual requirements, which is not specifically limited herein.

In some embodiments, the shape of the frame body may correspond to the shape of the light guide plate, for example, the shape of the frame body may be the same as the shape of the light guide plate. In other embodiments, the shape of the frame may not correspond to the shape of the light guide plate, for example, the shape of the frame may be different from the shape of the light guide plate. The position of the light guide plate is not particularly limited as long as the position can be defined by the frame.

In some embodiments, the light guide plate can convert a point light source or a line light source into a surface light source, has a high refractive index, and does not absorb light, so that the light guide plate can provide a light source required for displaying for electronic display products. The light guide plate may have a plate-shaped structure.

In some embodiments, the light guide plate may be made of an organic polymer material, so that the light guide plate has high light transmittance. Among them, the organic polymer material may include: acrylic, polymethyl methacrylate or transparent polycarbonate. In some embodiments, the material for manufacturing the light guide plate may be selected according to the requirement, and is not particularly limited herein. For example, the light guide plate may be made of an acryl material. For another example, the light guide plate may be made of polymethyl methacrylate.

In some embodiments, a side of the light guide plate facing the frame body is formed with a first recessed area, and in the case of disposing the light guide module in the electronic display, the first recessed area may correspond to a non-display area in the display screen. For example, the light guide module is applied to a smart phone, and a camera and other structures in the smart phone can be arranged in a non-display area.

In some embodiments, the shape of the first concave region may be set according to actual requirements, and is not particularly limited herein. For example, as shown in fig. 1, a first depression region 103 may be formed at a middle position of a top end of the light guide plate 102, and the shape of the first depression region 103 may be set to a water drop shape. For another example, fig. 2 is a sectional view of the light guide plate according to an exemplary embodiment, and as shown in fig. 2, the shape of the first concave area 103 at the middle position of the top end of the light guide plate 102 may also be set to be a bang shape.

In some embodiments, the light guide module may further include: a light deflecting assembly. The light deflection assembly can be positioned between the light guide plate and the frame body, so that the light output by the first sunken area can be deflected to the frame body by the light deflection assembly; wherein at least part of the light deflection assembly is opposite to the first recessed area of the light guide plate.

In some embodiments, the light deflecting component is a device that can change the direction of light propagation. Here, the light deflecting unit may be independently disposed between the light guide plate and the frame, and in order to deflect the light output from the first recess region to the frame by the light deflecting unit, a refractive index of the light guide plate may be different from a refractive index of the light deflecting unit. For example, the light guide plate and the light deflecting member may be made of different materials.

In some embodiments, the light deflecting member has a refractive index different from that of the light guide plate.

In some embodiments, the refractive index of the light deflecting member and the refractive index of the light guide plate may be selected according to actual requirements, as long as the refractive index of the light deflecting member is different from the refractive index of the light guide plate, and is not particularly limited herein. For example, the light guide plate is made of acrylic material, and the light deflecting assembly is made of transparent polycarbonate material, at this time, the refractive index of the light guide plate is 1.49, and the refractive index of the light deflecting assembly is 1.58.

Fig. 3 is a first schematic diagram illustrating light propagation according to an exemplary embodiment, and as shown in fig. 3, when light exits from the first concave region 103 along the first direction 301, the light deflecting assembly 104 not only reflects the light along the second direction 302, but also refracts the light along the third direction 303 due to the difference between the refractive index of the light deflecting assembly and the refractive index of the light guiding plate, so as to change the light propagation direction.

In some embodiments, since the refractive index of the light deflecting element is different from the refractive index of the light guide plate, the light deflecting element can reflect the light output from the first recessed area to the first recessed area, and can also refract the light output from the first recessed area to the frame body, so that the frame body reflects the light to the first recessed area, and thus the light can be transmitted to each part of the first recessed area, and the first recessed area is uniform in brightness.

In other embodiments, the light guide plate and the light deflection assembly may be made of the same material, and here, in order to change the transmission direction of the light by the light deflection assembly, the flatness of the light deflection assembly may be changed, so that the light deflection assembly is set to have a special-shaped structure, and thus, the light emitted from the first recess region may be adjusted by the light deflection assembly, and the light may be transmitted from various directions. For example, the light deflecting element may be disposed in an uneven structure opposite to the first recessed area, and the uneven structure may be formed by at least one arc-shaped segment.

In some embodiments, the shape of the light deflecting component may correspond to the shape of the first recessed region, e.g., the shape of the light deflecting component may be the same as the shape of the first recessed region. In other embodiments, the shape of the light deflecting element may not correspond to the shape of the first recessed area, for example, the shape of the light deflecting element may not be the same as the shape of the first recessed area, as long as the light deflecting element can change the transmission direction of the light output by the first recessed area, and is not limited herein. For example, when the first recessed area is in the shape of a water drop, the light deflecting element may also be in the shape of a water drop. For another example, when the first recessed area is in the shape of a water drop, the light deflecting element may be a rectangular parallelepiped.

In some embodiments, the light deflecting assembly covers the first recessed area, and the shape of the light deflecting assembly is the same as that of the first recessed area, so that the light deflecting assembly can be integrally formed on the first recessed area of the light guide plate, the receiving rate of the light deflecting assembly for receiving the output light of the first recessed area can be improved, the conductivity of the light deflecting assembly can be improved, and the purpose of reducing light loss is achieved.

Fig. 4 is a cross-sectional view of a second light guide module according to an exemplary embodiment, as shown in fig. 4, the first recessed area 103 is shaped like a water drop, and in order to make the light deflecting element 104 cover the first recessed area 103, the light deflecting element 104 may also be shaped like a water drop, such that the light deflecting element 104 is integrally formed on the side of the light guide plate 102 having the first recessed area 103.

In some embodiments, since at least a portion of the light deflecting assembly is opposite to the first recessed area on the light guide plate, the light deflecting assembly can be used to receive the light output from the first recessed area, adjust the transmission direction of the light, change the transmission direction of the light, and transmit the light with the changed transmission direction to the frame, so that at least a portion of the light deflected to the frame by the light deflecting assembly can be reflected to the first recessed area by the frame

In the embodiment of the disclosure, the light deflection assembly is disposed between the frame and the light guide plate, and at least a part of the light deflection assembly is opposite to the first recessed area of the light guide plate, so that the light output from the first recessed area can be deflected to the frame by the light deflection assembly, and at least a part of the light deflected to the frame by the light deflection assembly can be reflected to each part of the first recessed area by the frame.

In some embodiments, the light deflecting assembly comprises:

In some embodiments, the light deflecting assembly may include: the concave-convex structure can enable the light-emitting surface of the concave-convex structure to be opposite to the frame body, and therefore the transmission direction of light output from the first concave area can be changed by the concave-convex structure. For example, fig. 5 is a second schematic diagram illustrating light propagation according to an exemplary embodiment, and fig. 5 is an enlarged schematic diagram of a dotted-line box in fig. 4, as shown in fig. 5, the concave-convex structure 501 may refract the light in the first direction 502 output from the first recessed region 103 and then emit the light in the second direction 503, so that the transmission direction of the light output from the first recessed region 103 may be changed, and the light may be propagated to the frame body. Wherein the first direction 502 and the second direction 503 have an angle therebetween.

In some embodiments, the light deflecting assembly is configured to be an uneven structure, and the light output by the first recessed area can be uniformly deflected to the frame body by the uneven structure, so that at least part of the light deflected to the frame body by the light deflecting assembly is uniformly reflected to each part of the first recessed area by the frame body, and the first recessed area can uniformly emit light, thereby improving the light efficiency of the first recessed area.

As shown in fig. 5, the concave-convex structure 501 may include: a concave portion 504 and a convex portion 505; here, the concave portion 504 and the convex portion 505 may be a uniform and equally large arc-shaped structure. In some embodiments, the radius of the arc-shaped structure may be set according to actual requirements, and is not specifically limited herein. For example, the radius of the arcuate structure may be between 40 nanometers and 100 nanometers.

Fig. 6 is a third schematic view illustrating light propagation according to an exemplary embodiment, as shown in fig. 6, in the case that the light deflecting assembly is not disposed between the frame body and the light guide plate, when the light propagates from the light guide plate 102 to the first recessed area 103, the light is refracted at the first recessed area 103, so that the light propagates onto the frame body 101, and the light is reflected by the frame body 101 and then reaches the first recessed area 103. At this time, the first concave area 103 may be divided into three segments, which are an AB segment, a BC segment and a CD segment, where the AB segment and the CD segment may shine due to the existence of light, and the BC segment may dim due to the absence of light, which may cause uneven brightness of the first concave area 103.

In order to solve the problem of uneven brightness of the first recessed area, a light deflection assembly can be arranged between the frame body and the light guide plate. In some embodiments, the light deflecting element may cover the first recessed area, such that the light deflecting element may be integrally formed with the first recessed area. Fig. 7 is a fourth schematic view illustrating light propagation according to an exemplary embodiment, as shown in fig. 7, light output from the first concave area 103 is refracted by the concave portion and the convex portion in the concave-convex structure, so that the light can be transmitted to the frame body 101 from various directions, and the light can reach the first concave area 103 after being reflected by the frame body 101, so that brightness of the first concave area 103 is uniform. At this time, the first concave area 103 can be divided into three segments, which are an EF segment, an FG segment and a GH segment, and as can be seen from fig. 6, the concave portion and the convex portion in the concave-convex structure can change the propagation direction of the light, so that the light can reach the FG segment after being reflected by the frame 101, and thus the FG segment can be lightened due to the existence of the light.

In some embodiments, the transmission direction of the light output by the first concave region is adjusted by using the concave portion on the concave-convex structure and the convex portion on the concave-convex structure, so that the light is transmitted to the frame body from all directions of the first concave region, and the frame body can reflect the light to all parts of the first concave region, thereby realizing uniform brightness and darkness of the first concave region.

In some embodiments, the concave-convex structure is formed to extend from the first concave region on the light guide plate toward the frame body.

In some embodiments, the concave-convex structure may be integrally formed on the first concave region of the light guide plate by an injection molding method or an etching process; the first concave area can be processed by a striker, so that a concave-convex structure is formed in the first concave area.

In some embodiments, the concave-convex structure may be formed by extending from the first concave region on the light guide plate toward the frame body, so that the light emitting surface of the concave-convex structure faces the frame body, and the concave-convex structure is used to adjust the propagation direction of the light output from the first concave region, so that the light is transmitted to the frame body according to a required direction, and then reflected by the frame body to uniformly irradiate the first concave region, so that the brightness of the first concave region is uniform.

Fig. 8 is a cross-sectional view of a light guide module according to an exemplary embodiment, and as shown in fig. 8, a second concave region 801 is formed in the frame body 101 in a direction toward the first concave region 103 on the light guide plate 102, and a concave direction of the second concave region 801 is the same as a concave direction of the first concave region 103.

In some embodiments, the second recessed area is formed in the frame body in a direction toward the first recessed area on the light guide plate, and the recessed direction of the second recessed area is the same as the recessed direction of the first recessed area, so that the shape of the light guide plate can be more matched with the shape of the frame body, and the light guide plate can be limited.

In some embodiments, the light deflecting element is located between the first and second recessed regions, and the shape of the light deflecting element is the same as the recessed shape of the first and second recessed regions.

In some embodiments, the light deflecting assembly is disposed between the first recessed area and the second recessed area, and the shape of the light deflecting assembly is the same as the recessed shapes of the first recessed area and the second recessed area, so that the light output from the first recessed area can be deflected to the second recessed area by the light deflecting assembly, and further, the light transmittance can be improved, and the light loss can be reduced.

In some embodiments, by providing at least one light guide point on the backlight surface of the light guide plate, light rays input to the light incident surface of the light guide plate can be transmitted to the first recessed area by using each light guide point, so that the light rays can be output from the first recessed area, and thus, the light rays output from the first recessed area can be deflected by using the light ray deflection structure, so that the transmission direction of the light rays output from the first recessed area can be adjusted, and the light rays can be transmitted to the frame body according to the required direction, and then are reflected by the frame body and uniformly irradiate onto the first recessed area.
