Description

Technical Field

[0001] This utility model relates to the field of electronic display device technology, and specifically to a display module. Background Technology

[0002] Display modules, especially LCD display modules, are widely used in devices such as mobile phones, tablets, monitors, and televisions. A display module typically includes a display panel and a backlight module that provides the light source. In existing technology, the frame of the backlight module often uses a combination of a separate plastic frame and a metal frame. That is, the optical components are first placed inside the plastic frame, and then the metal frame is used to wrap around and lock it in place.

[0003] This structure has the following obvious drawbacks: First, the large number of parts requires separate mold making and inventory management, increasing material costs and management complexity; second, the assembly process is cumbersome and production efficiency is low; third, the independent iron frame and plastic frame structure makes the overall module heavy, and there are assembly tolerances between the two, which can easily lead to frame distortion or component damage due to stress concentration. In particular, when subjected to external impacts or collisions, the stress is most concentrated at the corners, which can easily cause frame deformation or even damage to internal optical components, affecting the display effect. Utility Model Content

[0004] To address some or all of the problems existing in the prior art, this utility model provides a display module, including an outer frame, a display panel, and a backlight module. The outer frame is a one-piece plastic-iron structure frame, formed by encasing a metal skeleton inside plastic using a plastic-coated metal injection molding process. The outer frame has a primary mounting groove, and a secondary mounting groove is provided on the primary mounting groove. The backlight module is connected to the primary mounting groove, and the display panel is connected to the secondary mounting groove. The display panel is located on the light-emitting side of the backlight module. Clearance spaces are provided on the outer frame at positions corresponding to the four corners of the display panel.

[0005] As a further improvement of this utility model, the clearance space is a groove provided on the inner side wall of the outer frame.

[0006] As a further improvement of this utility model, the backlight module includes a reflective sheet, a light guide plate, a lower diffuser plate, a brightness enhancement sheet, and an upper diffuser plate that are sequentially bonded together.

[0007] As a further improvement of this utility model, the number of brightness enhancement sheets is at least two.

[0008] As a further improvement of this utility model, a backlight strip is provided on one side of the light guide plate, and a plurality of lamp beads are provided on the backlight strip, the light emitted by the lamp beads can illuminate the light guide plate.

[0009] As a further improvement of this utility model, the outer walls of the outer frame are respectively wrapped with edge-sealing films, and the edge-sealing films are attached to the front end face of the display panel.

[0010] As a further improvement of this utility model, the display panel is an LCD panel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model adopts an integrated glue-iron frame, combining two originally separate components into one, reducing the number of parts, simplifying material management and supply chain, and lowering overall material costs. It also avoids the fit problems caused by assembly tolerances between traditional glue and iron frames, resulting in superior overall integrity, rigidity, and dimensional stability of the outer frame.

[0013] 2. This utility model eliminates the step of assembling the iron frame, simplifies the assembly process, and improves production efficiency and product yield.

[0014] 3. The corner clearance provided by this utility model can effectively prevent and disperse stress concentration. When subjected to collision or compression, it provides buffer space for the deformation of the outer frame, greatly reducing the risk of corner cracking and damage to internal optical components, and improving the reliability and durability of the product.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0023] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown, a display module includes an outer frame 1, a display panel 2, and a backlight module. The outer frame 1 is a one-piece plastic-iron structure frame, formed by encasing a metal skeleton in plastic using a plastic-coated metal injection molding process. The outer frame 1 has a primary mounting groove 11, and a secondary mounting groove 12 on the primary mounting groove 11. The backlight module is fixedly installed in the primary mounting groove 11, and the display panel 2 is fixedly installed in the secondary mounting groove 12, with the display panel 2 positioned on the light-emitting side of the backlight module. By providing the primary mounting groove 11 and the secondary mounting groove 12, the backlight module and the display panel 2 can be fixedly installed within the outer frame 1, improving the structural stability. Clearance positions 13 are provided on the outer frame 1 at the four corners corresponding to the display panel 2.

[0026] In this embodiment, the clearance 13 is a groove provided on the inner sidewall of the outer frame 1. By providing the groove, a gap is reserved between the corner of the display panel 2 and the inner sidewall of the outer frame 1, which can reduce the possibility of the inner display panel 2 being damaged by impact to the corner of the outer frame 1. In other embodiments, the clearance 13 can also be a clearance notch provided at the corner of the outer frame 1.

[0027] The backlight module includes a reflective sheet 3, a light guide plate 4, a lower diffuser plate 5, a brightness enhancement film 6, and an upper diffuser plate 7, which are sequentially bonded together. The reflective sheet 3 is bonded to the inner wall of the outer frame 1. A backlight strip 8 is provided on one side of the light guide plate 4, and multiple LEDs 9 are mounted on the backlight strip 8. The light emitted by the LEDs 9 can illuminate the light guide plate 4, which then guides the light towards the display panel 2. The reflective sheet 3 reflects the light from the LEDs 9 illuminating the inner wall of the outer frame 1 towards the light guide plate 4, reducing light loss. The lower diffuser plate 5 and the upper diffuser plate 7 diffuse the light transmitted from the light guide plate 4, making the light illuminating the display panel 2 more uniform and softer, avoiding halo effects. The brightness enhancement film 6 enhances the light brightness, thereby increasing the display brightness of the display panel 2.

[0028] In this embodiment, there are two brightness enhancement sheets 6. By using two brightness enhancement sheets 6, the brightness of the light can be further improved, thereby increasing the display brightness of the display panel 2 and enhancing the user experience. In other embodiments, the number of brightness enhancement sheets 6 may exceed two.

[0029] In this embodiment, the lamp beads 9 on the backlight strip 8 are LED lamp beads, thereby reducing the energy consumption of the display module and improving the light efficiency; and multiple lamp beads 9 are evenly distributed on the backlight strip 8, thereby making the light brightness of the entire display panel 2 more uniform and improving the display effect of the display panel 2.

[0030] In this embodiment, the display panel 2 is an LCD panel. In other embodiments, the display panel 2 can also be any other existing electronic component or device capable of realizing electronic display function.

[0031] To ensure a stable connection between the display panel 2 and the outer frame 1, edge-sealing films 10 are wrapped around the outer walls of the outer frame 1 on all four sides. The edge-sealing films 10 are attached to the front face of the display panel 2. By attaching the edge-sealing films 10 to the display panel, the display panel 2 can be fixed in place by the upper limit of the outer frame 1, thereby improving the stability of the structure.

[0032] This display module adopts a one-piece glue-iron frame, combining two originally separate components into one. This reduces the number of parts, simplifies material management and the supply chain, and lowers overall material costs. It also avoids the fit problems caused by assembly tolerances in traditional glue-iron frames, resulting in superior overall frame integrity, rigidity, and dimensional stability. Furthermore, by incorporating clearances at the four corners of the frame, stress concentration is effectively prevented and dispersed. These clearances provide buffer space for frame deformation during impacts or compression, significantly reducing the risk of corner cracking and damage to internal optical components, thus improving product reliability and durability.

[0033] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
