The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0052] The present application embodiment provides a light splitting component 11. Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 A schematic diagram of the structure of a light splitting component provided in one embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the splitter assembly from another perspective; Figure 3 for Figure 1 Schematic diagram of the connection between the light splitting component, the light emitting element and the light board; Figure 4 for Figure 3 Schematic diagram of the structure inverted after the section along the AA line. In this embodiment, the light splitting component 11 includes a light splitting element 111 and a plurality of light guides 112. The light splitting element 111 has a receiving space 1111 to receive the light emitting element 13. The plurality of light guides 112 are arranged at intervals and carried on the light splitting element 111, and the plurality of light guides 112 are used to receive the light beams emitted by the light emitting element 13 and guide the light beams out. For the convenience of illustration, Figure 4 for Figure 3 Schematic diagram of the structure after being rotated 180° and inverted along the AA line section.
[0053] In this embodiment, the light splitting component 11 is applied to the display module 1 (see Fig.15 ), specifically applied to the backlight module 10 in the display module 1 (see Fig.12 For example, the light splitting component 11 can be applied to, but not limited to, a display module of a mobile phone, a display module of a tablet computer, a display module of a notebook computer, a display module of a handheld computer, a display module of a personal computer (PC), a display module of a personal digital assistant (PDA), etc.
[0054] In this embodiment, the light splitter 111 has a receiving space 1111, so that the light splitter 111 can receive the light emitting element 13 (see Figure 4 ). The receiving space 1111 is a space in which the light beam emitted by the light emitting element 13 propagates inside the light splitter 111. The light beam emitted by the light emitting element 13 may be, but is not limited to, reflected, refracted, scattered, etc. inside the receiving space 1111. Optionally, the structure of the light splitter 111 is similar to a box-like structure, which can be called a light splitter box.
[0055] Optionally, the light-emitting element 13 may be, but is not limited to, a mini light-emitting diode (mini LED), a micro light-emitting diode (micro LED), or a diode (LED). In this embodiment, the light-emitting element 13 is exemplified as a mini LED.
[0056] In addition, in this embodiment, the plurality of light guides 112 are arranged at intervals and carried on the light splitter 111, and the light guide 112 is light-transmissive and can transmit the light emitted by the light emitting element 13. The material of the light guide 112 is a light-guiding material, for example, the material of the light guide 112 can be but not limited to a transparent polycarbonate (PC) material. The light beam emitted by the light emitting element 13 can be incident on the plurality of light guides 112, so that the light splitter component 11 emits a plurality of independent light beams through the plurality of light guides 112 to present the same number of light-emitting points as the light guide 112. Since the plurality of light beams emitted by the light splitter component 11 are independent of each other, they appear as a plurality of light-emitting point-shaped light sources from the outside of the light splitter component 11, and therefore, the plurality of independent light beams emitted by the light splitter component 11 are also referred to as light-emitting points, and the number of the light-emitting points is the same as the number of light beams emitted by the light splitter component 11, that is, the number of the light-emitting points is the same as the number of the light guides 112. When the light splitting component 11 is applied to the backlight module 10, the backlight module 10 emits a light beam through the light splitting component 11, so the number of light-emitting points of the light splitting component 11 is the number of light-emitting points of the backlight module 10. When the light splitting component 11 is applied to the display module 1, each light splitting component 11 is used to decompose the light beam emitted by a light-emitting element 13 into multiple independent light beams and guide them into the module optical cavity of the display module 1 (for details about the module optical cavity, please refer to the subsequent introduction of the display module 1), so as to ensure that the number of light beams emitted by the display module 1 remains unchanged, and the amount of the light-emitting element 13 is greatly reduced (for example, reduced by 2 times, 3 times, 4 times, or more than 4 times), thereby reducing the cost of the entire display module 1, which is conducive to product promotion.
[0057] Optionally, the plurality of light guides 112 may be disposed on the light splitter 111 by, but not limited to, bonding, embedding, or snap-fitting, as long as the light beam emitted by the light emitting element 13 can be guided out.
[0058] Optionally, in a spectroscopic component 11, the number of the light guides 112 is greater than or equal to 2. For example, the number of the light guides 112 may be, but is not limited to, 2, 3, 4, or more than 4. As long as the light guide 112 is set so that the number of light beams emitted by one spectroscopic component 11 is greater than or equal to 2, it will be sufficient. In the related art, one light emitting element 13 is used to emit one light beam, so N light emitting elements 13 are required to obtain N light beams. When the number of the light guides 112 is N, where N ≥ 2, then the number of light beams emitted by one spectroscopic component 11 is N. Then, when the same number of light beams is obtained, the spectroscopic component 11 provided in the embodiment of the present application can reduce the number of light emitting elements 13 compared with the related art, specifically by N times.
[0059] In the present embodiment, one of the beam splitters 111 accommodates one of the light emitting elements 13, so that the beam splitter component 11 can decompose the light beam emitted by one of the light emitting elements 13 into multiple independent light beams through the multiple light guides 112. In other embodiments, the number of light emitting elements 13 accommodated in one of the beam splitters 111 is m, and the number of light guides 112 in one of the beam splitters 111 is n, wherein n>m, m≥2. For example, m can be but is not limited to 2, or 3, or more than 3, etc., and the corresponding n is any value greater than m. As long as the number n of the light guides 112 accommodating m light emitting elements 13 in one of the beam splitters 111 is greater than the number m of the light emitting elements 13 accommodated in the accommodating space 1111 of the beam splitter 111, the number of light beams emitted by the beam splitter component 11 can be increased. It should be noted that the embodiment of the present application is schematically illustrated by using one beam splitter 111 accommodating one light emitting element 13. It can be understood that one beam splitter 111 accommodating other numbers of light emitting elements 13 should also fall within the protection scope of the present application.
[0060] In summary, the present application provides a spectroscopic component 11, wherein the spectroscopic component 11 accommodates the light-emitting element 13 through the spectroscopic component 111, so that the light beam emitted by the light-emitting element 13 is transmitted in the accommodating space 1111 of the spectroscopic component 111, and the light beam emitted by the light-emitting element 13 is guided into multiple independent light beams through the multiple light guides 112, thereby realizing that one spectroscopic component 11 decomposes a light beam emitted by the light-emitting element 13 into multiple independent light beams for emission, that is, the number of light-emitting points of the spectroscopic component 11 is increased, thereby ensuring that when the spectroscopic component 11 is applied to the backlight module 10, the number of light-emitting points of the entire backlight module 10 remains unchanged, and the amount of the light-emitting element 13 is reduced to reduce the cost. Therefore, the spectroscopic component 11 provided in the present application can increase the number of light-emitting points by decomposing the light beam emitted by the light-emitting element 13, so as to reduce the amount of the light-emitting element 13, thereby reducing the cost.
[0061] Please refer again Figure 2 and Figure 4 In this embodiment, the light splitter 111 has a plurality of mounting grooves 1112 and a plurality of light holes 1113. The plurality of mounting grooves 1112 are arranged around the receiving space 1111, and the mounting grooves 1112 are used to install the light guide 112. The light holes 1113 are used to connect the mounting grooves 1112 and the receiving space 1111, and the inner diameter of the light holes 1113 on the side close to the receiving space 1111 is larger than the inner diameter on the side close to the mounting grooves 1112.
[0062] In this embodiment, the plurality of light guide members 112 are installed through the plurality of installation grooves 1112 arranged around the receiving space 1111 , and one light guide member 112 is correspondingly installed in one installation groove 1112 .
[0063] Optionally, the mounting groove 1112 accommodates part of the light guide member 112 , or the mounting groove 1112 accommodates the entire light guide member 112 .
[0064] In this embodiment, the light through hole 1113 is used to connect the installation groove 1112 and the receiving space 1111, so that the light beam emitted by the light-emitting element 13 received in the receiving space 1111 can pass through the light through hole 1113 to be incident on the light guide 112 installed in the installation groove 1112, and be exported through the light guide 112.
[0065] Furthermore, the inner diameter of the light-through hole 1113 on the side close to the receiving space 1111 is larger than the inner diameter on the side close to the mounting groove 1112, so that when the light beam emitted by the light-emitting element 13 accommodated in the receiving space 1111 is incident from the side of the receiving space 1111 through the light-through hole 1113 into the mounting groove 1112, the light-splitting component 111 limits the inner wall of the light-through hole 1113 so that the outer diameter of the light beam emitted by the light-emitting element 13 becomes smaller, thereby concentrating the light beam and improving the light beam energy, thereby making the brightness of the light beam entering the mounting groove 1112 and entering the light guide 112 higher, thereby improving the brightness of multiple independent light beams emitted by the light-splitting component 11.
[0066] Optionally, the aperture of the light hole 1113 decreases continuously from the aperture close to the receiving space 1111 to the inner diameter close to the mounting groove 1112 , or the inner wall of the light hole 1113 defined by the light splitting element 111 is in a stepped structure.
[0067] Optionally, a focusing lens is disposed inside the light hole 1113 to converge the light beam in the receiving space 1111 into the mounting groove 1112 to increase the brightness of the light beam entering the light guide member 112 .
[0068] For further information, please refer to Figure 4 and Figure 5 , Figure 5 for Figure 4 In this embodiment, the light guide 112 has a light incident surface 1121, and the light incident surface 1121 is arranged at an angle with the central axis of the light hole 1113, and the angle α satisfies: 30°≤α≤60°.
[0069] In this embodiment, the light guide member 112 has a light incident surface 1121, and the light incident surface 1121 is arranged at one end of the light guide member 112 close to the receiving space 1111, and the light incident surface 1121 is arranged toward the light through hole 1113. The light beam emitted by the light-emitting element 13 received in the receiving space 1111 is incident on the light incident surface 1121 via the light through hole 1113, so as to be emitted from the top of the light guide member 112 which is arranged opposite to the light incident surface 1121.
[0070] Wherein, the light incident surface 1121 is set at an angle with the central axis of the light hole 1113, and the angle α satisfies: 30°≤α≤60°, so that the light guide 112 can refract the light beam and emit it from the top, thereby reducing light loss. For example, the angle α can be but is not limited to 30°, or 35°, or 40°, or 45°, or 50°, or 55°, or 60°, or any angle value within the above range. If the angle α is less than 30° or greater than 60°, the light beam will be reflected more at the light incident surface 1121, or, after being refracted by the light incident surface 1121, it will enter the light guide 112 and then be emitted from the side wall of the light guide 112, thereby causing light loss, thereby affecting the effect of the light beam emitted by the light splitting component 11. Therefore, the angle α satisfies: 30°≤α≤60°, so that the light beam can be emitted from the top after being refracted by the light incident surface 1121, thereby reducing light loss.
[0071] Please refer again Figure 2 In this embodiment, the inner wall of the light splitter 111 defining the receiving space 1111 includes a top wall 1114. The top wall 1114 is arc-shaped and is concave in a direction away from the opening of the receiving space 1111. The arc is symmetrical about the center of the top wall 1114. The distances between the centers of the plurality of light guides 112 and the top wall 1114 are the same.
[0072] In this embodiment, when the light splitting component 11 is applied to the backlight module 10, the light emitting element 13 accommodated in the accommodation space 1111 is arranged opposite to the top wall 1114, and the light beam emitted by the light emitting element 13 will be reflected on the top wall 1114. The top wall 1114 is arc-shaped and is concave in a direction away from the opening of the accommodation space 1111, that is, it is concave in a direction away from the light emitting element 13, which is conducive to the reflection of the light beam. Among them, since the top wall 1114 is arc-shaped and used to reflect the light beam emitted by the light emitting element 13, the top wall 1114 is also called a reflective dome.
[0073] Furthermore, the arc is symmetrical about the center of the top wall 1114, which is conducive to the uniform reflection of the light beam emitted by the light emitting element 13 on the top wall 1114. When the light splitting component 11 is applied to the backlight module 10, the orthographic projection of the light emitting element 13 on the top wall 1114 falls on the center of the top wall 1114.
[0074] In addition, the distances between the multiple light guides 112 and the centers of the top wall 1114 are the same, that is, the distances between the multiple light guides 112 and the light emitting elements 13 accommodated in the accommodation space 1111 are the same, so that the light beams emitted by the light emitting elements 13 are uniform after being transmitted in the accommodation space 1111 and entering the multiple light guides 112, thereby making the light emission of the multiple light guides 112 uniform, that is, improving the light emission effect of the spectroscopic component 11.
[0075] Please refer to Figure 6 and Figure 7 , Figure 6 for Figure 4 Schematic diagram of the structure of the light splitter; Figure 7 for Figure 6 Schematic diagram of the cross-sectional structure along line BB in FIG. In this embodiment, the light splitter 111 includes a light splitter body 1115 and an optical reflective layer 1116. The light splitter body 1115 has the receiving space 1111. The optical reflective layer 1116 is disposed on the inner wall of the light splitter body 1115 defining the receiving space 1111. The thickness h1 of the optical reflective layer 1116 satisfies: 0.01 mm ≤ h1 ≤ 0.05 mm.
[0076] In this embodiment, the optical reflective layer 1116 is used to reflect the light beam emitted by the light emitting element 13 contained in the containing space 1111, so as to assist the light beam emitted by the light emitting element 13 to enter the light through hole 1113. Specifically, the optical reflective layer 1116 is disposed on the inner wall of the containing space 1111 defined by the light splitting body 1115. In addition, when the light splitting component 11 is applied to the backlight module 10, the optical reflective layer 1116 is also disposed on the surface of the light board 12 located in the backlight module 10 in the containing space 1111, and is disposed away from the light emitting element 13, so as to reflect the light beam emitted by the light emitting element 13.
[0077] Optionally, the material of the light splitting body 1115 may be, but is not limited to, plastic, rubber, metal, etc., which is not limited here.
[0078] Optionally, the material of the optical reflective layer 1116 may include, but is not limited to, barium sulfate, glass, silver, aluminum, etc.
[0079] Furthermore, the thickness h1 of the optical reflective layer 1116 satisfies: 0.01mm≤h1≤0.05mm, so that the optical reflective layer 1116 can better adhere to the inner wall of the receiving space 1111 defined by the light-splitting body 1115, and has a good reflective effect. For example, the thickness h1 of the optical reflective layer 1116 can be, but is not limited to, 0.01mm, or 0.02mm, or 0.03mm, or 0.04mm, or 0.05mm, or any value in the above range. If the thickness h1 of the optical reflective layer 1116 is less than 0.01mm, the optical reflective layer 1116 is easy to transmit light, so that the light-splitting body 1115 absorbs part of the light beam, resulting in poor reflection effect of the optical reflective layer 1116, and further resulting in poor light output effect of the light-splitting component 11. If the thickness h1 of the optical reflective layer 1116 is greater than 0.05 mm, the optical reflective layer 1116 is too thick and is easy to fall off from the light splitting body 1115, or is easy to form pits, so that the reflection effect of the optical reflective layer 1116 is poor, and further leads to poor light extraction effect of the light splitting component 11. Therefore, the thickness h1 of the optical reflective layer 1116 satisfies: 0.01 mm ≤ h1 ≤ 0.05 mm, which can improve the light extraction effect of the light splitting component 11.
[0080] Please refer again Figure 2 and Figure 4 In this embodiment, the light splitter 111 has an end surface 1117, and the receiving space 1111 passes through the end surface 1117. The end surface 1117 is used to connect the bearing surface 121 of the lamp board 12. The mounting groove 1112 passes through the end surface 1117, and the opening direction of the mounting groove 1112 is the same as the opening direction of the receiving space 1111. The light guide 112 is disposed in the mounting groove 1112, and the light guide 112 is exposed at one side of the mounting groove 1112.
[0081] In this embodiment, the opening direction of the mounting groove 1112 is the same as the opening direction of the receiving space 1111, and the receiving space 1111 passes through the end surface 1117. Therefore, when the light splitting component 11 is applied to the backlight module 10, the direction of the light emitted by the light-emitting element 13 accommodated in the receiving space 1111 is opposite to the direction of the light emitted by the multiple light guides 112, which is beneficial for the light splitting component 111 to reflect the light beam emitted by the light-emitting element 13 to the multiple light guides 112, thereby decomposing a light beam into multiple independent light beams for emission.
[0082] In addition, the light splitter assembly 11 further includes a positioning member, which is disposed on the end surface 1117 of the light splitter 111 and is used to assist the light splitter 111 in being fixed to the light board 12 so as to make the installation of the positioning member more stable. Optionally, the positioning member is disposed at four end corners of the end surface 1117.
[0083] In addition, the beam splitter 111 has a plurality of grooves, which are recessed on the end face 1117 for reducing material, thereby making the beam splitter 111 lighter, which is beneficial to lightweight design. The inner walls of the grooves defined by the beam splitter 111 can resist external forces through elastic deformation, thereby making the structure of the beam splitter 111 more stable.
[0084] Please refer to Figure 4 , Figure 8 and Fig. 9 , Figure 8 for Figure 4 Schematic diagram of the structure of the medium bonding adhesive; Fig. 9 for Figure 4 The partial enlarged schematic diagram at I in the figure. In this embodiment, the light splitting component 11 also includes an adhesive 113. The adhesive 113 is arranged on the end surface 1117, avoiding the opening of the receiving space 1111 and the light guide 112, and is used to bond the light splitting component 111 and the light board 12. The gap h2 between the adhesive 113 and the light guide 112 satisfies: 0.2mm≤h2≤0.5mm.
[0085] In this embodiment, the adhesive 113 is used to bond the light splitter 111 to the lamp board 12. Since the adhesive 113 is disposed on the end surface 1117 and avoids the opening of the receiving space 1111, the adhesive 113 is also called "mouth glue".
[0086] In this embodiment, the adhesive 113 is disposed away from the opening of the receiving space 1111 and the light guide 112 to avoid affecting the reflection and emission of the light beam emitted by the light emitting element 13 received in the receiving space 1111 .
[0087] Further, the gap h2 between the adhesive 113 and the light guide 112 satisfies: 0.2mm≤h2≤0.5mm, that is, the adhesive 113 has a hole that matches the gap of the light guide 112, which is conducive to bonding the adhesive 113 to the end face 1117. For example, the gap h2 between the adhesive 113 and the light guide 112 can be, but is not limited to, 0.2mm, or 0.3mm, or 0.4mm, or 0.5mm, or any value within the above range. If the gap h2 between the adhesive 113 and the light guide 112 is less than 0.2mm, it is easy for the adhesive 113 to adhere to the light guide 112 during the process of adhering to the end face 1117, thereby causing the adhesive 113 to be damaged. If the gap h2 between the adhesive 113 and the light guide 112 is greater than 0.5 mm, the hole on the adhesive 113 that fits the gap with the light guide 112 is too large, resulting in too little bonding between the adhesive 113 and the end face 1117, and thus making it less stable for the adhesive 113 to bond the light splitter 111 to the light board 12. Therefore, the gap h2 between the adhesive 113 and the light guide 112 satisfies: 0.2 mm ≤ h2 ≤ 0.5 mm, which is beneficial for the adhesive 113 to bond to the end face 1117 and for the adhesive 113 to bond the light splitter 111 to the light board 12 stably.
[0088] Optionally, when the light splitting component 11 further includes a positioning member, the adhesive 113 is further provided with a hole that is clearance-matched with the positioning member to prevent the positioning member from affecting the adhesive 113 .
[0089] In other implementations, the adhesive 113 may also be provided in the area of the light board 12 for mounting the light splitting component 11 .
[0090] Please refer again Figure 2 and Figure 4 In this embodiment, the light splitting component 11 further includes an optical glue 114. The optical glue 114 is disposed on the light splitting component 111 and is used to fix the light guide component 112.
[0091] In this embodiment, the light guide 112 is fixed to the light splitter 111 by optical adhesive 114 , which can not only fix the light guide 112 but also does not affect the light guiding of the light beam by the light guide 112 .
[0092] Optionally, the optical adhesive 114 may be, but is not limited to, silicone adhesive, optical clear adhesive (OCA), optical pressure sensitive adhesive (PSA), polyurethane reactive (PUR) adhesive, polyurethane (PU) adhesive, or other suitable optical grade adhesive materials.
[0093] Optionally, when the light splitter 111 has a plurality of mounting grooves 1112 , the optical adhesive 114 is disposed in the mounting grooves 1112 to fix the light guide 112 .
[0094] The present application also provides a backlight module 10. Fig.10 , Fig.11 and Fig.12 , Fig.10 A schematic diagram of the structure of a backlight module provided in one embodiment of the present application; Fig.11 for Fig.10 A three-dimensional exploded diagram of the backlight module; Fig.12 for Fig.10 In the embodiment, the backlight module 10 includes a light board 12, a plurality of light emitting elements 13 and a plurality of light splitting components 11 as described in any of the above embodiments. The light board 12 has a bearing surface 121. The plurality of light emitting elements 13 are arranged on the bearing surface 121 at intervals. One light splitting component 11 is arranged corresponding to one light emitting element 13 and is connected to the bearing surface 121. For the convenience of illustration, Fig.12 for Fig.10 Schematic diagram of the structure after being rotated 180° and inverted along the CC line section.
[0095] In this embodiment, one of the light splitting components 11 is provided corresponding to one of the light emitting elements 13 , which means that the light splitting element 111 in the light splitting component 11 accommodates the light emitting element 13 .
[0096] Optionally, the light emitting element 13 may be, but is not limited to, directly mounted on the light board 12 or plugged into the light board 12 .
[0097] In other embodiments, one of the light splitting components 11 is provided corresponding to one of the light emitting elements 13, which means that the light beam emitted by the light emitting element 13 is directly incident on the light splitting component 11, and the light splitting component 11 is a structure having multiple light guide paths, so as to divide the light beam emitted by one of the light emitting elements 13 into multiple paths for export, so as to realize decomposing the light beam emitted by one of the light emitting elements 13 into multiple independent light beams. For example, the light splitting component 11 includes a light guide bar and multiple light guide portions, and the multiple light guide portions are convexly arranged on the same surface of the light guide bar at intervals, and one end of the light guide bar is provided corresponding to the light emitting element 13 to receive the light beam emitted by the light emitting element 13, and emit the light beam through the multiple light guide portions to form multiple independent light beams. It can be understood that the light splitting component 11 including the light guide bar and the multiple light guide portions is only a schematic example, and the specific structure of the light splitting component 11 is not limited, as long as the light splitting component 11 can decompose the light beam emitted by one of the light emitting elements 13 and export multiple independent light beams.
[0098] In this embodiment, the backlight module 10 decomposes the light beam emitted by the light-emitting element 13 into multiple independent light beams through the light-splitting component 11, thereby achieving the goal that one light-splitting component 11 decomposes a light beam emitted by the light-emitting element 13 into multiple independent light beams, that is, the number of light-emitting points of the light-splitting component 11 is increased, thereby ensuring that the number of light-emitting points of the entire backlight module 10 remains unchanged, and reducing the amount of the light-emitting element 13 to reduce costs.
[0099] This application also provides a display module 1. Please refer to Fig.13 , Fig.14 , Fig.15 and Fig.16 , Fig.13 A schematic diagram of the structure of a display module provided in one embodiment of the present application; Fig.14 for Fig.13 The three-dimensional exploded diagram of the display module is shown in the figure;
[0100] Fig.15 for Fig.13 The schematic diagram of the inverted structure after the section along the DD line in the middle; Fig.16 for Fig.15 Schematic diagram of light path propagation of the display module. In this embodiment, the display module 1 includes a stacked display panel 30 and a backlight module 10 as described in the above embodiment. For the convenience of illustration, Fig.15 for Fig.13 Schematic diagram of the structure after being rotated 180° and inverted along the DD line section.
[0101] In this embodiment, each of the light splitting components 11 is provided corresponding to one of the light emitting elements 13, and is used to emit multiple light beams to the display panel 30. The display module 1 of this embodiment uses each of the light splitting components 11 in the backlight module 10 to decompose the light beam emitted by one of the light emitting elements 13 into multiple independent light beams and guide them into the module optical cavity of the display module 1, so as to ensure that the number of light beams emitted by the display module 1 remains unchanged, and the amount of the light emitting element 13 is greatly reduced (for example, reduced by 2 times, 3 times, 4 times, or more than 4 times), thereby reducing the cost of the entire display module 1, which is beneficial to product promotion.
[0102] The module optical cavity is located between the backlight module 10 and the display panel 30 .
[0103] Please refer to Fig.14 , Fig.15 , Fig.16 and Fig.17 , Fig.17 for Fig.14 Schematic diagram of the structure of the middle light board. In this embodiment, the light board 12 has a plurality of hole groups 122. Each hole group 122 includes a plurality of light guide holes 1221, and each hole group 122 corresponds to a light splitting component 11. The hole group 122 is used to transmit the light beam emitted by the light splitting component 11, and one light guide hole 1221 corresponds to transmitting one light beam.
[0104] In this embodiment, each of the light splitting components 11 decomposes the light beam emitted by a corresponding light emitting element 13 into multiple independent light beams, which are emitted from the corresponding hole group 122 , and one light guide hole 1221 correspondingly transmits one light beam.
[0105] Optionally, the light guide member 112 of the light splitting component 11 is disposed corresponding to the light guide hole 1221 and penetrates the light guide hole 1221 to emit the light beam through the light guide hole 1221 .
[0106] Optionally, when the light splitting component 11 further includes a positioning piece, the light board 12 further includes a matching piece that is matched and connected with the positioning piece, so as to position and install the light splitting component 11.
[0107] Please refer again Fig.14 , Fig.15 and Fig.16In this embodiment, the display module 1 further includes a back panel 20 and a plurality of scattering groups 40. The back panel 20 is disposed on a side of the light board 12 away from the light splitting component 11. The back panel 20 includes a plurality of light-transmitting portions 21 arranged at intervals. Each of the light-transmitting portions 21 includes a plurality of light-transmitting sub-portions 211. One of the light-transmitting sub-portions 211 is disposed corresponding to one of the light guide holes 1221. The light-transmitting sub-portion 211 is used to transmit a light beam emitted from the light guide hole 1221. Each of the scattering groups 40 includes a plurality of scattering elements 41. The plurality of scattering groups 40 are disposed on a side of the back panel 20 away from the light board 12, and one of the scattering elements 41 is disposed corresponding to one of the light-transmitting sub-portions 211. The scattering element 41 is an arc-shaped structure protruding in a direction away from the light board 12 to scatter the light beam transmitted through the light-transmitting sub-portion 211.
[0108] In this embodiment, the back panel 20 is arranged on the side of the lamp panel 12 away from the splitter component 11, so the light-emitting element 13 emits a light beam in the direction away from the back panel 20. The light beam emitted by the light-emitting element 13 is decomposed into multiple independent light beams by the splitter component 11 and then emitted in the direction of the back panel 20 to the scattering group 40. The scattering group 40 scatters the multiple independent light beams to form a uniform light beam and emits it to the display panel 30, which is beneficial to the uniform light emission of the display panel 30.
[0109] In this embodiment, one of the light-transmitting sub-sections 211 is disposed corresponding to one of the light-guiding holes 1221 , which means that the light beam can pass through the light-guiding hole 1221 to the light-transmitting sub-section 211 and be emitted through the light-transmitting sub-section 211 .
[0110] Optionally, the light-transmitting sub-portion 211 may be, but is not limited to, a hole, a light-transmitting film, a light-transmitting block, or the like.
[0111] In this embodiment, one scattering member 41 is disposed corresponding to one light-transmitting sub-portion 211 , which means that the light beam can pass through the light-transmitting sub-portion 211 to the scattering member 41 and be scattered by the scattering member 41 .
[0112] Optionally, the orthographic projection of the scattering element 41 on the light-transmitting sub-portion 211 covers at least a portion of the light-transmitting sub-portion 211 .
[0113] Furthermore, the scattering member 41 is an arc-shaped structure that protrudes in a direction away from the light board 12, so that after the light beam transmitted through the light-transmitting sub-portion 211 is incident on the scattering member 41, the light beam is scattered around the scattering member 41, thereby achieving a better scattering effect, and further making the light beam scattered to the display panel 30 through the multiple scattering groups 40 uniform, thereby achieving a better display effect.
[0114] Optionally, the scattering element 41 is a transparent optical adhesive, which may be, but is not limited to, silicone adhesive, optical clear adhesive (OCA), optical pressure sensitive adhesive (PSA), polyurethane reactive (PUR) adhesive, polyurethane (PU) adhesive, or other suitable transparent optical grade adhesives.
[0115] Furthermore, in the present embodiment, the light board 12 is disposed on the side of the back plate 20 away from the display panel 30. Since the back plate 20 is disposed on the side of the light board 12 away from the light splitting component 11, the entire backlight module 10 is disposed on the side of the back plate 20 away from the display panel 30, which is equivalent to the backlight module 10 being externally disposed relative to the back plate 20, and can also be referred to as the backlight module 10 being disposed on the outside of the back plate 20. On the first aspect, since the backlight module 10 is disposed on the outside of the back plate 20, the heat generated by the multiple light-emitting units 13 in the backlight module 10 can be dissipated to the outside more quickly, which is beneficial to the heat dissipation of the entire backlight module 10, thereby facilitating the heat dissipation of the display module 1. On the second aspect, the backlight module 10 being disposed on the outside of the back plate 20 can avoid a large optical distance (OD). On the third aspect, the backlight module 10 is arranged on the outer side of the back plate 20 to avoid seeing the multiple splitting components 11 (each of the splitting components 11 presents a dark shadow or a black mass) from the side of the display panel 30, thereby avoiding the splitting components 11 from affecting the display effect. Especially when the splitting components 11 are dark (for example, black), the backlight module 10 is arranged on the outer side of the back plate 20 to avoid the splitting components 11 from absorbing light, thereby avoiding affecting the light output intensity of the display module 1.
[0116] In other embodiments, the light board 12 may also be disposed on a side of the back plate 20 close to the display panel 30 , as long as the light splitting component 11 can decompose the light beam emitted by one light emitting element 13 into multiple independent light beams.
[0117] Please refer to Fig.18 , Fig.18 for Fig.15A partial enlarged schematic diagram at II in the figure. In this embodiment, the scattering member 41 abuts against the surface of the back panel 20 facing away from the light board 12, and covers the light-transmitting sub-portion 211. The distance d1 between the outer contour of the scattering surface of the back panel 20 abutted by the scattering member 41 and the outer contour of the orthographic projection of the light-transmitting sub-portion 211 on the scattering surface satisfies: 2mm≤d1≤5mm. The dimension d2 of the scattering member 41 in the direction from the light board 12 to the back panel 20 satisfies: 0.5mm≤d2≤1mm.
[0118] In this embodiment, the scattering member 41 abuts against the surface of the back plate 20 away from the light board 12 and covers the light-transmitting sub-portion 211 , so that the light beam passing through the light-transmitting sub-portion 211 can directly enter the scattering member 41 , thereby reducing light loss.
[0119] Furthermore, the scattering surface of the scattering member 41 abuts against the back plate 20, and the distance d1 between the outer contour of the positive projection of the light-transmitting sub-portion 211 on the scattering surface and the outer contour of the scattering surface satisfies: 2mm≤d1≤5mm, which can improve the scattering effect. For example, d1 can be but is not limited to 2mm, or 3mm, or 4mm, or 5mm, or any value within the above range. If d1 is less than 2mm, after the light beam enters the scattering member 41, in the direction perpendicular to the light-transmitting sub-portion 211 pointing to the scattering member 41, the light beam cannot be fully dispersed in the scattering member 41, resulting in poor scattering effect of the scattering member 41 on the light beam. If d1 is greater than 5mm, the scattering member 41 cannot further improve the scattering effect after d1 is greater than 5mm, but instead increases the cost of the scattering member 41. Therefore, the distance d1 between the outer contour of the orthographic projection of the light-transmitting sub-portion 211 on the scattering surface and the outer contour of the scattering surface satisfies: 2mm≤d1≤5mm, which can improve the scattering effect of the scattering element 41 and control the cost.
[0120] Furthermore, the dimension d2 of the scattering member 41 in the direction from the light board 12 to the back panel 20 satisfies: 0.5mm≤d2≤1mm, so that the scattering member 41 can have both better scattering effect and less light loss. For example, d2 can be, but is not limited to, 0.5mm, or 0.6mm, or 0.7mm, or 0.8mm, or 0.9mm, or 1mm, or any value within the above range. If d2 is less than 0.5mm, after the light beam enters the scattering member 41 through the light-transmitting sub-section 211, the light beam cannot be fully dispersed in the scattering member 41 in the direction from the light-transmitting sub-section 211 to the scattering member 41, resulting in poor scattering effect of the scattering member 41 on the light beam. If d2 is greater than 1mm, the absorption of the light beam by the scattering member 41 will be too obvious, resulting in greater light loss. In addition, if d2 is too large, the thickness of the display module 1 will be too thick, which is not conducive to a thin and light design. Therefore, the dimension d2 of the scattering member 41 in the direction from the light board 12 to the back board 20 satisfies: 0.5mm≤d2≤1mm, which enables the scattering member 41 to have a better scattering effect and less light loss, and also enables the display module 1 to be controlled at an appropriate thickness.
[0121] Please refer again Fig.14 , Fig.15 , Fig.16 and Fig.18 In this embodiment, the display module 1 further includes an optical film 50. The optical film 50 is disposed between the scattering member 41 and the display panel 30. The minimum distance d3 between the optical film 50 and the scattering member 41 satisfies: 0.1mm≤d3≤0.2mm, which can ensure the assembly gap between the optical film 50 and the scattering member 41 to avoid the scattering member 41 abutting against the optical film 50, thereby causing damage to the optical film 50. For example, d3 can be, but is not limited to, 0.1mm, or 0.15mm, or 0.2mm, or any value within the above range. If d3 is less than 0.1mm, when assembling the optical film 50 and the scattering member 41, the scattering member 41 is easily abutted against the optical film 50, thereby causing damage to the optical film 50. If d3 is too large, it will cause waste of space between the optical film 50 and the back plate 20, which is not conducive to the thin and light design of the display module 1. Therefore, the minimum distance d3 between the optical film 50 and the scattering element 41 satisfies: 0.1 mm≤d3≤0.2 mm, which is beneficial to the assembly between the optical film 50 and the scattering element 41 and can effectively utilize the space.
[0122] Optionally, the optical film 50 includes at least one of a diffusion film and a brightness enhancement film to improve the display effect of the display panel 30. The diffusion film is used to further evenly diffuse the light passing through the scattering element 41 so that the display panel 30 emits light evenly. The brightness enhancement film is used to further increase the brightness of the light passing through the scattering element 41 so as to improve the display effect of the display panel 30.
[0123] Please refer again Fig.15 , Fig.16 and Fig.18 In this embodiment, part of the light guide 112 is connected to the light splitter 111, and part of it is arranged corresponding to the light guide hole 1221 and the light-transmitting sub-section 211. The distance d4 between the surface of the light guide 112 close to the scattering member 41 and the scattering member 41 satisfies: 0.1mm≤d4≤0.2mm, so as to ensure the assembly gap between the light guide 112 and the scattering member 41, avoid the light guide 112 abutting against the scattering member 41 and causing damage to the scattering member 41, and enable the light guide 112 to better guide the light beam to the scattering member 41. For example, d4 can be but not limited to 0.1mm, or 0.15mm, or 0.2mm, or any value within the above range. If d4 is less than 0.1mm, the gap between the light guide 112 and the scattering member 41 is too small, and the light guide 112 is easy to abut against the scattering member 41 during assembly and cause damage to the scattering member 41. If d4 is greater than 0.2 mm, the gap between the light guide 112 and the scattering member 41 is too large, and the light beam is easily lost in the gap between the light guide 112 and the scattering member 41 after being guided out through the light guide 112, which is not conducive to the scattering of the light beam by the scattering member 41. Therefore, the distance d4 between the surface of the light guide 112 close to the scattering member 41 and the scattering member 41 satisfies: 0.1 mm ≤ d4 ≤ 0.2 mm, which can avoid damaging the scattering member 41 during the assembly process and is conducive to the transmission of the light beam.
[0124] Please refer again Fig.15 , Fig.16 and Fig.18 In this embodiment, the back plate 20 includes a main body 22 and an optical reflective coating 23. The main body 22 includes the plurality of light-transmitting portions 21 arranged at intervals. The optical reflective coating 23 is disposed on the surface of the main body 22 facing the display panel 30 and is disposed away from the plurality of light-transmitting portions 21, and is used to reflect the light beams scattered by the plurality of scattering members 41.
[0125] In this embodiment, the optical reflective coating 23 is used to reflect the light beam scattered by the scattering element 41 to reflect the light beam to the display panel 30, which can increase the utilization rate of light and make the light output of the display panel 30 more uniform.
[0126] Optionally, the material of the optical reflective coating 23 may include but is not limited to barium sulfate, glass, silver, aluminum, etc.
[0127] Furthermore, the thickness d5 of the optical reflective coating 23 satisfies: 0.03mm≤d5≤0.05mm, so that the optical reflective coating 23 can be better adhered to the main body 22 and has a good reflective effect. For example, the thickness d5 of the optical reflective coating 23 can be, but is not limited to, 0.03mm, or 0.04mm, or 0.05mm, or any value in the above range. If the thickness d5 of the optical reflective coating 23 is less than 0.03mm, the optical reflective coating 23 is easy to transmit light, so that the main body 22 absorbs part of the light beam, resulting in poor reflection effect of the optical reflective coating 23, and further resulting in poor light output effect of the display module 1. If the thickness d5 of the optical reflective coating 23 is greater than 0.05 mm, the optical reflective coating 23 is too thick and is easy to fall off from the main body 22, or is easy to form pits, so that the reflection effect of the optical reflective coating 23 is poor, and further leads to poor light emission effect of the display module 1. Therefore, the thickness d5 of the optical reflective coating 23 satisfies: 0.03 mm ≤ h1 ≤ 0.05 mm, which can improve the light emission effect of the display module 1.
[0128] Please refer again Fig.14 In this embodiment, the display module 1 further includes a bracket 60 and a plastic frame 70.
