Description

Technical Field

[0001] The utility model relates to the field of display technology, in particular to a display module structure. Background Art

[0002] Liquid crystal display modules are widely used in various occasions due to their advantages such as lightness, low energy consumption and no radiation. The display panel in the liquid crystal display module is a passive display device, so a backlight module needs to be set to provide light to be refracted by the display panel to display the picture. The backlight module generally includes a bottom frame and a light guide plate, a light-emitting component, a variety of optical films and a middle frame arranged on the bottom frame, and the middle frame is used to carry the display panel. The existing backlight display module with a middle iron frame has a significant weakening of the strength of the iron frame because a window needs to be set in the middle of the iron frame, especially on the IC side, because the glass shape is relatively large on this side, and the iron frame support surface is far away from the iron frame shape, which is most prone to deformation. After the LCD screen is assembled, the middle iron frame will be pressed down due to the self-gravity of the display screen, and there is a hidden danger of crushing the backlight film material.

[0026] Embodiment 1

[0027] like Figure 1 As shown, the utility model provides a display module structure, comprising a bottom frame 1, a light guide plate 2 and an optical film 3 are arranged on the bottom frame 1, and a light emitting component 7 is arranged on one side of the light guide plate 2;

[0028] The middle frame 4 is sleeved on the bottom frame 1. The middle frame 4 is provided with a support platform 42 for supporting the display panel. The support platform 42 is provided with a window for light transmission and a reinforcing rib 41 facing the display panel 5. The reinforcing rib 41 is provided at a position of the support platform 42 close to the window and is located on the same side as the driver IC 501 of the display panel 5.

[0029] The reinforcing rib 41 is an arched convex strip and is integrally formed with the supporting platform 42 .

[0030] In this embodiment, the middle frame 4 is a metal frame, and the reinforcing ribs 41 are prism bars and are integrally formed with the support platform. In this way, by setting the reinforcing ribs 41 on the support platform 42, the strength of the support platform 42 is actually strengthened. Since the display panel 5 is mounted on a local position of the support platform 42, the support platform 42 without the reinforcing ribs is similar to a single board with local stress without reinforcement, and it is easy to be pressed and deformed at the local stress position. After the reinforcing ribs 41 are added, the reinforcing ribs 41 have a reinforcing effect on the support platform 42, and enhance the strength of the support platform 42 itself, so that it can have a better anti-deformation effect, so that the support platform 42 does not produce downward deformation or only undergoes a slight downward deformation, and the optical film 3 can be protected from being supported. The support platform 42 is pressed down to produce wrinkles or deformation, which affects the backlight effect. At the same time, since the reinforcing ribs 41 are arranged on the side of the support platform 42 facing the display panel 5, the reinforcing ribs 41 can only have an effective reinforcing effect if they meet a sufficient height condition. Since the display panel 5 itself has a certain height, the reinforcing ribs are arranged on the side of the support platform 42 facing the display panel 5. There is space for the arrangement, which can ensure that the reinforcing ribs 41 have sufficient height and strength. There is no need to add other components to ensure the height of the reinforcing ribs 41, and there is no need to make changes to the optical film 3, which makes the production process simple and fast, and can effectively improve production efficiency and product quality.

[0031] In this embodiment, the reinforcing rib 41 is arranged on the bottom side of the driver IC 501 of the display panel 5 on the upper surface of the middle frame 4, which is closer to the window position at the bottom of the middle frame, thereby greatly improving the strength of the middle frame, and can greatly improve the strength and compressive deformation resistance of the middle frame, thereby improving the problem of deformation and pressure damage to the film material of the middle frame due to the influence of gravity after assembling the liquid crystal display screen, thereby improving the quality of the product.

[0032] Further, the middle frame 4 is a metal frame, and the reinforcing ribs 41 are prism bars and are integrally formed with the support platform 42. Since metal frames are difficult to form, using prism bars as reinforcing ribs is difficult to implement in terms of technology and has high costs, and also greatly increases the weight of the middle frame 4. Using arched convex bars as reinforcing ribs of the metal frame ring platform can be directly convexed through the metal frame, which is convenient for production and does not affect the weight of the middle frame 4. Further, the metal frame can be an aluminum frame or an iron frame.

[0033] Embodiment 2

[0034] like Figure 2 and Figure 3 As shown, the length of the reinforcing rib 41 exceeds the single side of the window opening of the middle frame 4 by 1 mm.

[0035] Furthermore, the reinforcing rib 41 has a width of 0.8 mm.

[0036] Furthermore, the distance between the reinforcing rib 41 and the bottom of the display panel 5 is 0.2 mm.

[0037] Furthermore, a ring-shaped foam double-sided adhesive tape 6 is provided on the support platform 42 on the side facing the display panel 5 .

[0038] Furthermore, the reinforcing rib 41 is spaced 0.5 mm to 1.0 mm from the foam double-sided adhesive tape 6 .

[0039] In this embodiment, in order to maximize the effect of the reinforcing rib 41 through the above structural design, the length of the reinforcing rib 41 is 1mm larger than the single side of the iron frame window; the width of the reinforcing rib 41 is designed to be 0.8mm to ensure its feasibility of molding; and the reinforcing rib 41 is designed to be 0.5mm-1.0mm away from the foam double-sided tape, so that it is as close to the light-emitting area window as possible and there is no interference with the foam. In addition, in order to avoid interference between the reinforcing rib 41 and the display panel 5, the height of the reinforcing rib 41 is 0.2mm away from the bottom of the display panel 5.

[0040] In this embodiment, the light emitting assembly 7 includes an FPC 72 and a plurality of top-emitting LEDs 71 disposed on the FPC 72. The light guide plate 2 is provided with at least one protrusion at the light incident surface, and the protrusion is located between adjacent LEDs 71 on the FPC 72 and presses the FPC 72. The FPC 72 is thin and light in structure, which can effectively reduce the thickness of the frame and the weight of the backlight module. However, since the FPC 72 generates a rebound force against bending at the place where it needs to be bent, it is also easy to warp, especially when heated at high temperatures. After the protrusion is provided at the position of the light guide plate 2 corresponding to the FPC 72, the protrusion can press the FPC 72, effectively preventing the FPC 72 from warping.

[0041] Embodiment 3

[0042] like Figure 2 As shown, the display panel 5 includes an upper polarizer 51, a liquid crystal display screen 52 and a lower polarizer 53 stacked in sequence. The polarizer has a fixed polarization axis, which only allows light with a vibration direction consistent with the polarization direction to pass through, and absorbs light with a vibration direction perpendicular to the polarization axis, and is used to convert natural light without polarization into polarized light, allowing light with a direction perpendicular to the electric field to pass through, so that the liquid crystal display panel can display images normally.

[0043] The liquid crystal display screen 52 described in this embodiment is filled with liquid crystal material. Among them, the liquid crystal is a special substance that has properties between liquid and solid. The liquid crystal molecules are arranged in an orderly manner when there is no external influence, but when subjected to external effects such as electric field, temperature or pressure, the liquid crystal molecules will change their arrangement structure, thereby producing different optical properties. Liquid crystal materials are usually composed of organic molecules or polymers, which have a long shape so that they can form a specific arrangement structure in the liquid crystal state. According to the arrangement mode of liquid crystal molecules, liquid crystals can be divided into various types, including nematic liquid crystals, twisted nematic liquid crystals, helical liquid crystals, etc. Liquid crystal materials are widely used in display technology, especially in liquid crystal displays. In liquid crystal displays, liquid crystal materials are filled between two pieces of glass to form a liquid crystal layer. When an electric field is applied, the arrangement structure of the liquid crystal molecules will change, thereby changing the polarization state of light passing through the liquid crystal layer to achieve image display.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
