Description

Technical Field

[0001] This utility model relates to the field of automotive backlight components, and in particular to a backlight structure and display device with uniform light effect. Background Technology

[0002] Automotive backlighting products mainly include instrument panel backlighting, center console backlighting, and seat control backlighting, widely used in vehicle dashboards, infotainment systems, and navigation systems. Automotive backlighting products are primarily composed of components such as foam, upper and lower brightness enhancement elements, diffusers, light guide plates, reflectors, aluminum frame light strips, heat-conducting adhesive for the light strips, and film material adhesive. With continuous improvements in technology and user requirements, automotive backlighting products feature narrower bezels and higher screen-to-body ratios. Due to the high brightness requirements of automotive projects, the lamp driving current differs significantly from that of consumer mobile phones and tablets. Automotive lamps typically use 80 / 100 / 120mA, while consumer mobile phones and tablets generally use 19~23mA. Therefore, the light source structure and effect of the backlight in automotive projects differ greatly from those in consumer mobile phones and tablets.

[0003] In existing technologies, automotive backlight products typically have a large distance between the lamps, resulting in short optical paths and high brightness. However, due to the increasingly narrow backlight bezels, the distance between the light source and the visible area of ​​the back panel in the automotive backlight structure is becoming even closer. Furthermore, the light emission angle of the LEDs used in the light source is an angle, such as... Figure 6 As shown, this results in a dark area forming in the light guide plate between two adjacent lights, which appears as a dark area and shadow in the visible area, affecting the backlight effect.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] To address the problem in existing technologies where the increasingly narrow bezels of automotive backlight products result in the light source being closer to the visible area of ​​the back panel, and the large distance between lamps, short optical path, and high brightness in the light source of automotive backlight products leads to the formation of dark areas and shadows in the visible area due to the luminous angle between adjacent light sources, this invention provides a backlight structure and display device with uniform light effect.

[0006] This utility model is achieved through the following technical solution:

[0007] A backlight structure with a uniform light effect, wherein the backlight structure with a uniform light effect comprises:

[0008] A base frame, wherein a plurality of light source elements are uniformly arranged on one inner wall of the base frame;

[0009] An adhesive component is attached to the bottom side of the base frame. Several reflective parts are respectively provided on the adhesive component at positions corresponding to adjacent light source components. Each reflective part includes two reflective bevels symmetrically arranged along a predetermined angle.

[0010] A light guide plate is attached to the adhesive component. One side of the light guide plate is equidistant from several of the light source components. The light from the light source components is diffusely reflected along the light guide plate towards the reflective part and the reflective oblique edge towards one side of the adhesive component.

[0011] The backlight structure with uniform light effect is provided in which a reflective layer is attached to the bottom plate of the base frame, the adhesive component is attached to the reflective layer, and the light guide plate covers the adhesive component and the reflective layer.

[0012] The backlight structure with uniform light effect is described above, wherein the reflective part is an isosceles trapezoid, and the two reflective hypotenuses are the two isosceles hypotenuses of the reflective part; the shorter side of the bottom edge of the reflective part is set away from the light source.

[0013] The backlight structure with uniform light effect is provided with positioning parts at both ends of the adhesive component, and the two positioning parts are respectively attached to the corner part corresponding to the side of the light source component in the base frame.

[0014] The backlight structure with uniform light effect is provided in such a way that a clearance portion is provided on one side of the adhesive component corresponding to the plurality of light source components. The clearance portion is recessed and is used to avoid the plurality of light source components.

[0015] The backlight structure with uniform light effect is wherein a plurality of the reflective parts and two of the positioning parts are integrally formed on the adhesive part.

[0016] The backlight structure with uniform light effect includes a base frame comprising an enclosing panel, a light source component disposed on one side of the enclosing panel, and the light guide plate having all sides except the side corresponding to the light source component abutting against the enclosing panel.

[0017] The backlight structure with uniform light effect, wherein the backlight structure with uniform light effect includes:

[0018] A membrane material assembly is attached to one side of the light guide plate and engaged with a plurality of protrusions on the light guide plate.

[0019] The backlight structure with uniform light effect, wherein the film material component includes a lower diffusion film, a lower brightness enhancement film, and an upper brightness enhancement film;

[0020] Alternatively, the membrane assembly may include a lower diffusion film, a lower brightness enhancement film, an upper brightness enhancement film, and an upper diffusion film.

[0021] A display device, wherein the display device includes the backlight structure with uniform light effect described above.

[0022] The beneficial effects of this utility model are as follows: By setting several reflective parts on the glued part corresponding to the positions of adjacent light source components, and reflective inclined surfaces on both sides of the reflective parts, when two adjacent light source components emit light, the dark area generated by the intersection of light rays is diffusely reflected by the reflective parts and reflective inclined surfaces and then emitted forward. This can reduce the phenomenon of uneven brightness and darkness, while increasing the bonding area of ​​the light guide plate, taking into account both the backlight display effect of the visible area and the fixing effect of the light guide plate, and improving product quality.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] In existing technologies, automotive backlight products typically have a large distance between the lamps, resulting in short optical paths and high brightness. However, due to the increasingly narrow backlight bezels, the distance between the light source and the visible area of ​​the back panel in the automotive backlight structure is becoming even closer. Furthermore, the light emission angle of the LEDs used in the light source is an angle, such as... Figure 6 As shown, this results in a dark area forming in the light guide plate between two adjacent lights, which appears as a dark area and shadow in the visible area, affecting the backlight effect.

[0034] To address the aforementioned problems in the existing technology, this utility model provides a backlight structure with uniform light distribution, such as... Figure 1 and Figure 2 As shown, the backlight structure with uniform light effect includes: a base frame 100, on which a plurality of light source elements 110 are uniformly arranged on one inner wall; an adhesive component 200, which is attached to the bottom side of the base frame 100, and a plurality of reflective parts 210 are respectively arranged on the adhesive component 200 at positions corresponding to adjacent light source elements 110, the reflective part 210 including two reflective inclined edges 211 symmetrically arranged along a predetermined angle; and a light guide plate 300, which is attached to the adhesive component 200, one side of the light guide plate 300 is equidistant from the plurality of light source elements 110, and the light from the light source is diffusely reflected along the light guide plate 300 to one side of the adhesive component 200 via the reflective parts 210 and the reflective inclined edges 211.

[0035] This invention provides several reflective parts 210 on the adhesive part 200 corresponding to the positions of adjacent light source parts 110, as well as reflective inclined surfaces on both sides of the reflective parts 210. When two adjacent light source parts 110 emit light, the dark areas generated by the intersection of light rays are diffusely reflected by the reflective parts 210 and the reflective inclined surfaces 211 and then emitted forward. This can reduce uneven brightness and increase the bonding area of ​​the light guide plate 300, taking into account both the backlight display effect of the visible area and the fixing effect of the light guide plate 300, thereby improving product quality.

[0036] In the above embodiments, such as Figure 1 As shown, the main body of the backlight structure with uniform light effect of this utility model consists of a base frame 100, an adhesive component 200, and a light guide plate 300. The base frame 100 serves as the frame structure for the vehicle-mounted backlight structure and acts as the mounting base for other functional components. In this embodiment, a plurality of light source components 110 are provided on one inner wall of the base frame 100. The light source component 110 is specifically an LED lamp bead. When the light source component 110 emits light, the light enters the light guide plate 300 at the corresponding position. The light guide plate 300 scatters the LED point light source into a uniform, unidirectional, and usable "surface light source" throughout the entire surface, turning the originally horizontally propagating light into a vertical direction (i.e., shooting out towards the front of the visible area).

[0037] In this embodiment, the main component that achieves the light-uniforming effect is the adhesive component 200. The adhesive component 200 is attached to the bottom side of the base frame 100. The adhesive component 200 is essentially a double-sided component; after being attached and fixed to the base frame 100, its other side is used to attach and fix the light guide plate 300. In the prior art, the adhesive component 200 is a strip-shaped component, such as... Figure 6 As shown, in the prior art, the adhesive component 200 only serves to fix the light guide plate 300, while in this application, the shape of the adhesive component 200 is configured as follows: Figure 1 and Figure 2 As shown, the glued component 200 is provided with a plurality of reflective portions 210, which are respectively disposed at positions between adjacent light source components 110. The glued component 200 also includes two reflective bevels 211 symmetrically arranged along a predetermined angle. Please refer to... Figure 4 Since the light guide plate 300 is attached to the top of the adhesive component 200, the reflective part 210 provided on the adhesive component 200 increases the contact area between it and the light guide plate 300, allowing the mating structure at the light guide plate 300 to be installed in a narrower frame space. On the other hand, the reflective part 210 and the reflective slope carry the residual light of the light source 110, causing the residual light to be diffusely reflected on the upper side of the reflective part 210 and the reflective slope, forming a uniform light effect in the direction of the light guide plate 300. This uniform light effect fills the dark area generated by the angle between adjacent light sources 110, thus reducing the phenomenon of uneven brightness in the visible area.

[0038] On the other hand, when the light guide plate 300 is attached to the adhesive component 200, one side of the adhesive component 200 and the side of the light guide plate 300 corresponding to the light source component 110 are installed in a parallel and equidistant manner with respect to the light source components 110. Therefore, in actual use, the light generated by the light source components 110 enters along the edge of the light guide plate 300 and is diffusely reflected towards the reflective part 210 and the reflective slope, forming the effect of filling the dark area generated by the angle between adjacent light source components 110 with light.

[0039] Based on the above embodiments, in actual settings, such as Figure 4 As shown, a reflective layer is also attached to the bottom plate of the aforementioned base frame 100. Specifically, the reflective layer is a reflective sheet or reflective film, whose function is to recover lost light. When light is incident on the light guide plate 300 from the light source 110, approximately 25-35% of the light escapes from the bottom and sides of the light guide plate 300. The reflective sheet is coated with silver or TiO2, with a reflectivity ≥95%, which can reflect almost all of this light back into the light guide plate 300, directly increasing the axial brightness of the light in the light guide plate 300 by 20-30%. In this embodiment, the aforementioned adhesive component 200 is attached to the reflective layer 400, and the light guide plate 300 covers both the adhesive component 200 and the reflective layer 400. The reflective layer 400, in conjunction with the diffuse reflection of the adhesive component 200, further optimizes the overall brightness uniformity of the backlight structure, achieving uniform filling of dark areas and effectively reducing light loss during transmission in dark areas, ensuring that more light is guided to the visible area, thereby enhancing the display effect.

[0040] In another possible embodiment of this utility model, such as Figure 2 As shown, the reflective part 210 can be specifically configured as an isosceles trapezoid, with the two reflective hypotenuses 211 being the two isosceles hypotenuses of the reflective part 210. Specifically, in actual installation, the shorter side of the bottom edge of the reflective part 210 should be positioned away from the light source 110, so that when the reflective hypotenuse 211 produces diffuse reflection, most of the light can be refracted into the direction of the light guide plate 300. Combined with the optical characteristics of the light guide plate 300 and the reflective layer 400, this ensures that the light can be evenly distributed within the light guide plate 300, thereby eliminating dark areas and shadows.

[0041] Based on the above embodiments, in another possible embodiment of this utility model, in order to further improve the assembly accuracy and stability of the adhesive component 200 in the backlight structure, such as... Figure 1 and Figure 2As shown, positioning parts 220 are provided at both ends of the glued part 200. The shape of the positioning part 220 is adapted to the shape of the corner part inside the base frame 100 (the base frame 100 is usually rectangular). Therefore, the positioning part 220 can help the assembly personnel to accurately attach the glued part 200 to the corner part inside the base frame 100 corresponding to the side of the light source 110, so as to play the role of fixing and limiting.

[0042] Furthermore, since a certain distance should be maintained between the light source 110 and the light guide plate 300 in the backlight structure to ensure better light transmission, to facilitate accurate control of this installation distance by assembly personnel, such as... Figure 1 and Figure 2 As shown, a clearance portion 230 is also provided on the above-mentioned adhesive component 200. The clearance portion 230 is recessed. The clearance portion 230 can avoid the mounting positions of several light source components 110, so that the corresponding structure is installed compactly and the width of the frame is further reduced. On the other hand, it provides a reference for the assembly of the light guide plate 300, so that the assembly of the light guide plate 300 can be accurately operated.

[0043] In the above embodiments, the structures on the glued part 200, such as several reflective parts 210, two positioning parts 220, and the glued part 200 itself, can all be integrally processed by molding technology to ensure the consistency of the glued part 200 size during mass production, as well as the consistency of the assembly of the light guide plate 300 and other functional components, thereby significantly improving the product yield.

[0044] In addition, to further improve the accuracy of the installation of the light guide plate 300, such as Figure 1 and Figure 2 As shown, the aforementioned base frame 100 also includes a surrounding plate 120 that encloses the base frame 100. The surrounding plate 120 encloses the base plate of the base frame 100. The aforementioned plurality of light source elements 110 are located on one inner wall of the surrounding plate 120. The length and width dimensions of the surrounding plate 120 corresponding to the base plate of the base frame 100 are preset so that when the light guide plate 300 is accurately installed, except for the side corresponding to the light source element 110, the other sides of the light guide plate 300 are evenly aligned with the surrounding plate 120. Thus, the surrounding plate 120 achieves the function of limiting and calibrating the light guide plate 300. At the same time, the surrounding plate 120 forms a barrier on the light-emitting surface of the side of the light guide plate 300 to prevent light from escaping from the side of the light guide plate 300, further improving the light utilization rate and preventing light leakage. In addition, the presence of the surrounding plate 120 also enhances the overall strength of the base frame 100, enabling it to better protect the internal components when subjected to external impact or vibration, and extending the service life of the backlight structure.

[0045] In another embodiment of this utility model, the aforementioned backlight structure with uniform light effect further includes a film assembly 500. Specifically, the film assembly 500 comprises several stacked functional films. The shape of the film assembly 500 is adapted to the shape of the light guide plate 300 to receive the light reflected by the light guide plate 300 to achieve a more uniform backlight effect. The film assembly 500 is specifically connected to the light guide plate 300 via an adhesive structure. This adhesive structure assists in the positioning of the film assembly 500 and prevents relative displacement between the film assembly 500 and the light guide plate 300 due to impacts, vibrations, or other factors during actual use. Figure 1 and Figure 3 As shown, in this embodiment, a number of protrusions 310 are pre-set on the light guide plate 300. Correspondingly, a slot structure corresponding to the number of protrusions 310 is provided on the film material assembly 500. The film material assembly 500 achieves precise positioning and stable connection with the light guide plate 300 through the cooperation of the protrusions 310 and the slot structure. On the one hand, it simplifies the assembly process, and on the other hand, it can avoid the problems of offset, loosening and wrinkling that may occur in the film material assembly 500 during use, thereby ensuring the stability and consistency of the backlight effect.

[0046] Based on the above embodiments, in one specific embodiment of this utility model, such as Figure 4 As shown, the above-mentioned film material assembly 500 includes a lower diffuser film 510, a lower brightness enhancement film 520, and an upper brightness enhancement film 530. The lower diffuser film 510 is closely attached to the light guide plate 300 and uses internal diffuser particles to perform secondary homogenization on the light-emitting surface, shielding defects such as dots and scratches on the light guide plate 300, while blurring the light spots, so that the subsequent film can obtain flawless uniform incident light. The surface prism array of the lower brightness enhancement film 520 converges large-angle light rays towards the normal direction, improving the front brightness, while recycling the light rays that are totally reflected back to the light guide plate 300, achieving the initial brightness gain. The direction of the prisms set on the upper brightness enhancement film 530 is usually orthogonal to the lower brightness enhancement film 520, further converging the remaining large-angle light rays, continuing to improve the axial brightness and improve the viewing angle distribution, completing the secondary brightness enhancement effect.

[0047] In another specific embodiment, in addition to the lower diffusion film 510, lower brightness enhancement film 520 and upper brightness enhancement film 530, the above-mentioned film material assembly 500 may also be provided with an upper diffusion film. The upper diffusion film is located at the top layer and has a low haze and high light transmittance design. On the one hand, it slightly diffuses the light to expand the viewing angle and soften the light, and on the other hand, it protects the lower brightness enhancement film from scratches and contamination, taking into account both appearance concealment and reliability.

[0048] Based on the above embodiments, the assembly process of the backlight structure with uniform light effect of this utility model is as follows:

[0049] Several light source components 110 are evenly installed on one inner wall of the base frame 100. A reflective layer 400 is attached to the bottom plate of the base frame 100. The positioning parts 220 at both ends of the adhesive component 200 are used for positioning to attach the adhesive component 200 to the reflective layer 400, ensuring that the reflective part 210 on the adhesive component 200 corresponds precisely to the position of the adjacent light source component 110.

[0050] After the installation of the adhesive component 200 is completed, the light guide plate 300 is attached to the adhesive component 200. One side of the light guide plate 300 corresponding to the light source component 110 corresponds to the relief portion 230 on the adhesive component 200, and the other side of the light guide plate 300 abuts against the enclosure plate 120.

[0051] Finally, the membrane assembly 500 is connected to the light guide plate 300 via an adhesive structure.

[0052] In practical use, such as Figure 5 As shown, when the light emitted by the light source 110 enters the light guide plate 300 at a certain angle, a dark area is formed between adjacent light sources 110 due to the intersection of light angles. Due to the presence of the reflective part 210 and the reflective bevel 211 provided on the adhesive part 200, the reflective part 210 and the reflective bevel 211 can diffusely reflect the residual light of the light source 110. The diffusely reflected light is reflected and refracted in the light guide plate 300 and then illuminates the area in front of the reflective part 210 (i.e., the original dark area). Therefore, the dark area can be effectively supplemented, and the uneven brightness phenomenon can be reduced.

[0053] Based on the above embodiments, the present invention also provides a display device, which includes the backlight structure with uniform light effect in the above embodiments. The backlight structure with uniform light effect includes: a base frame, on which a plurality of light source elements are uniformly disposed on one inner wall; an adhesive component, which is attached to the bottom side of the base frame, and a plurality of reflective portions are respectively disposed on the adhesive component at positions corresponding to adjacent light source elements, the reflective portions including two reflective inclined edges symmetrically disposed along a predetermined angle; and a light guide plate, which is attached to the adhesive component, one side of the light guide plate being equidistantly corresponding to a plurality of light source elements, and the light from the light source being diffusely reflected along the light guide plate towards the reflective portions and the reflective inclined edges towards one side of the adhesive component. This invention provides several reflective sections on the glued part corresponding to the positions of adjacent light sources, as well as reflective slopes on both sides of the reflective sections. When two adjacent light sources emit light, the dark areas generated by the intersection of light rays are diffusely reflected by the reflective sections and reflective slopes and then emitted forward. This can reduce uneven brightness while increasing the bonding area of ​​the light guide plate, taking into account both the backlight display effect of the visible area and the fixing effect of the light guide plate, thus improving product quality.

[0054] In summary, this utility model provides a backlight structure and display device with uniform light effect. The backlight structure with uniform light effect includes: a base frame, on which a plurality of light source elements are uniformly arranged on one inner wall; an adhesive component, which is attached to the bottom side of the base frame, and a plurality of reflective parts are respectively arranged on the adhesive component at positions corresponding to adjacent light source elements, the reflective parts including two reflective inclined sides symmetrically arranged along a predetermined angle; and a light guide plate, which is attached to the adhesive component, one side of the light guide plate is equidistant from the plurality of light source elements, and the light from the light source is diffusely reflected along the light guide plate towards the reflective parts and the reflective inclined sides towards one side of the adhesive component. This invention provides several reflective sections on the glued part corresponding to the positions of adjacent light sources, as well as reflective slopes on both sides of the reflective sections. When two adjacent light sources emit light, the dark areas generated by the intersection of light rays are diffusely reflected by the reflective sections and reflective slopes and then emitted forward. This can reduce uneven brightness while increasing the bonding area of ​​the light guide plate, taking into account both the backlight display effect of the visible area and the fixing effect of the light guide plate, thus improving product quality.

[0055] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
