Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to an electromagnetic plate side-insertion backlight module and display device. Background Technology

[0002] As modern office environments increasingly rely on pen displays, notebooks, and tablets, electromagnetic circuit board technology, as a core interactive component, directly impacts the user's handwriting input experience. Currently, electromagnetic flexible circuit boards and magnetic shielding sheets, as key materials for achieving electromagnetic induction, have made significant progress in accuracy and response speed, meeting the high-precision input requirements of professional drawing and note-taking. However, the physical thickness of these materials is becoming increasingly problematic. Traditional electromagnetic flexible circuit boards are typically 0.3-0.5 mm thick, and magnetic shielding sheets also need to maintain a certain thickness to ensure magnetic shielding effectiveness. This contradicts the ongoing trend towards thinner and lighter consumer electronic devices.

[0003] Excessively thick electromagnetic modules directly limit the portability and design flexibility of devices. For example, in foldable screen devices striving for extreme thinness and lightness, the thickness of the electromagnetic layer significantly increases the risk of screen creases; while for laptops that require prolonged handheld use, the bulky structure also increases wrist strain. More importantly, the current bottleneck in the thickness of electromagnetic materials hinders further compression of backlight display modules, making it difficult to achieve a thinner and lighter design while maintaining high performance. If this problem is not resolved, it will continue to constrain users' expectations for lightweight office devices and may even affect the future market competitiveness of products.

[0004] The main factors affecting the thickness of the backlight module include three aspects: First, for cost control reasons, traditional backlight designs usually use thicker conventional brightness enhancement film materials, which directly increases the overall thickness of the module; second, in existing designs, the electromagnetic plate is usually placed below the plastic frame, and its inherent thickness limits the further thinning of the backlight module; finally, the electromagnetic plate is currently generally installed on the front or back, which not only makes the installation process complicated and takes up a lot of space, but also affects the assembly efficiency and may interfere with the optical performance of the backlight module.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electromagnetic plate side-insertion backlight module, comprising an integrated glue and iron component and an electromagnetic plate, wherein the integrated glue and iron component includes a plastic frame, the top of which is provided with an insertion groove, the electromagnetic plate is inserted into the interior of the plastic frame through the insertion groove and is fixedly connected to the inner wall of the plastic frame by a connecting adhesive, and a reflective film, a light guide plate, a film assembly and a display screen are sequentially arranged on one side of the electromagnetic plate along the display direction.

[0007] As a further description of the above technical solution: the integrated plastic and iron component also includes a bent iron component, which is fixedly installed on the inner wall of the plastic frame, and a light strip is provided inside the U-shaped groove of the bent iron component.

[0011] As a further description of the above technical solution: a base is fixedly installed at the bottom of the plastic frame, and a support is fixedly connected between the base and the plastic frame.

It offers the following advantages: This invention achieves efficient assembly and performance optimization through an innovative design of the glue-iron structural components. It adopts a side-and-back window structure, with the specific material and window method adapted to the corresponding electromagnetic plate size. The electromagnetic plate is inserted through the side opening and fixed with single-sided adhesive. The reflective layer, light guide plate, and composite film are assembled sequentially, and finally, the entire structure is sealed with a sealing component. The glue frame and lower iron are integrally injection molded, avoiding the warping problem of the glue frame caused by the deformation of the traditional iron frame, ensuring stable optical performance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-3An electromagnetic plate side-insertion backlight module includes a glue-iron integrated component 1 and an electromagnetic plate 103. The glue-iron integrated component 1 includes a plastic frame 101, and the top of the plastic frame 101 has an insertion groove 2. The electromagnetic plate 103 is inserted into the interior of the plastic frame 101 through the insertion groove 2 and is fixedly connected to the inner wall of the plastic frame 101 by connecting adhesive. Along the display direction, a reflective film 5, a light guide plate 6, a film assembly 7, and a display screen 8 are also arranged sequentially on one side of the electromagnetic plate 103. The innovative design of the glue-iron structural component achieves efficient assembly and performance optimization. It adopts a side and back opening structure, and the specific materials and opening method are adapted to the size of the electromagnetic plate 103. The electromagnetic plate 103 is inserted from the side opening and fixed with single-sided adhesive. After assembling the reflective layer, the light guide plate 6, and the composite film in sequence, the overall structure is finally sealed with a sealing component 3. The glue frame and the lower iron adopt an integrated injection molding process, which avoids the problem of glue frame warping caused by the deformation of the traditional iron frame and ensures stable optical effect.

[0024] It is worth mentioning that the aforementioned reflective film 5, light guide plate 6, film assembly 7, and display screen 8 are all existing technologies. Their functions are as follows: after the light strip 9 emits light, the light enters the light guide plate 6 and is evenly distributed to the entire display area. The reflective film 5 reflects the light leaking from the bottom of the light guide plate 6 back to the light guide plate 6, improving the light utilization rate. The film assembly 7 further optimizes the light quality, making the light more uniform and brighter. Finally, the optimized light reaches the display screen 8, and a clear and bright image is presented through pixel control.

[0025] As a preferred technical solution of this embodiment, the integrated plastic and iron component 1 further includes a bent iron component 102, which is fixedly installed on the inner wall of the plastic frame 101.

[0026] As a preferred technical solution in this embodiment, a black and white reflective strip 13 is fixedly installed on the inner wall of the bent iron part 102. The black and white reflective strip 13 is closely attached to one side of the light strip 9, and a flexible circuit board 10 is electrically connected to the light strip 9. The black and white reflective strip 13 is assembled above the U-shaped bend of the plastic iron structure to prevent the light beam from the light strip 9 from being emitted, which would cause the brightness on both sides of the light source to weaken.

[0027] As a preferred technical solution of this embodiment, a sealing element 3 is provided inside the insertion groove 2, and the sealing element 3 and the insertion groove 2 are connected by sealant; the sealing element 3 is used to seal the insertion groove 2, thereby achieving the integrity of the device and completing the encapsulation of the internal parts.

[0028] A display device includes the aforementioned electromagnetic plate side-inserted backlight module, and also includes a protective screen 4, which is fixedly mounted on a plastic frame 101, and the display screen 8 is attached to the protective screen 4; the protective screen 4 is used to protect the display screen 8 and increase the protective performance of the device.

[0029] As a preferred technical solution in this embodiment, a base 12 is fixedly installed at the bottom of the plastic frame 101, and a support member 11 is fixedly connected between the base 12 and the plastic frame 101; the support member 11 and the base 12 are used to install the display module above, so that the display module is more complete and stable.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
