Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to a ruggedized touch display module. Background Technology

[0002] Traditional touch display modules typically employ a multi-layered adhesive structure consisting of a touchscreen, a display screen, double-sided adhesive, and a backlight module. While this structure enables basic display and touch functions, it reveals significant structural reliability issues in practical applications, particularly in environments with drastic temperature changes or frequent mechanical vibrations, such as automotive equipment and industrial control systems. Because the touchscreen, display screen, and backlight module rely entirely on adhesives for fixation, the adhesive materials are prone to softening and failure at high temperatures and embrittlement at low temperatures, leading to a significant decrease in bond strength. Simultaneously, continuous mechanical vibration can cause microcracks to form at the adhesive interface and gradually propagate, eventually leading to interlayer delamination. Furthermore, differences in the coefficients of thermal expansion between different materials can cause internal stress accumulation during temperature cycling, further exacerbating the risk of structural failure.

[0003] Chinese utility model patent (CN217521583U) discloses a fully laminated touch display module and its assembly structure. The touch display module includes a display panel, an OCA (Optical Characteristic Aspect Ratio), and a touch cover plate. The backlight includes a frame wall, and the display panel is disposed within the frame wall, with its upper surface flush with the upper surface of the frame wall. The OCA is slightly smaller than the backlight. The touch cover plate is attached to the display panel via the OCA. This utility model saves materials, reduces costs, and improves installation efficiency through full lamination of the touch display module. However, it still has significant shortcomings in structural strength and cannot solve the problem of the touch display module's robustness.

[0004] Therefore, developing a novel fixing structure for touch display modules that can significantly improve their structural reliability in harsh environments has important practical application value. Utility Model Content

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] Example 1

[0043] Please refer to Figures 1-7 This embodiment provides a ruggedized touch display module, which includes a touch display component 1, a support frame 2, and a backlight support frame 3. The support frame 2 is a rectangular frame structure with hollow top and bottom. The backlight support frame 3 is inserted from the bottom of the support frame 2 to form an open accommodating cavity. The touch display component 1 is placed in the cavity formed by the backlight support frame 3 and the support frame 2. A first fixing component is provided between the backlight support frame 3 and the support frame 2 for mutual fixation to achieve a reliable connection.

[0044] Furthermore, a top protective structure is provided above the touch display component 1 to prevent the touch display component 1 from shifting and falling off.

[0045] Specifically, such as Figure 2 As shown, the support frame 2 includes a frame sidewall 21 and a support frame 22, wherein the support frame 22 is a support flange formed by extending horizontally inward from the inner side of the frame sidewall 21.

[0046] Furthermore, such as Figure 3 As shown, the backlight support frame 3 includes a rectangular support frame base plate 31 and support frame sidewalls 32 extending upward along the four edges of the base plate 31.

[0047] Furthermore, the first fixing component comprises a first fixing protrusion 33 and a first fixing hole 24. The first fixing protrusion 33 consists of several protrusions disposed on the outer side of the support frame sidewall 32, and the first fixing hole 24 consists of several through holes penetrating the frame sidewall 21. The shapes and sizes of the first fixing protrusion 33 and the first fixing hole 24 are compatible. In use, the backlight support frame 3 is inserted from below the support frame 2 along the inner side of the frame sidewall 21. Once the first fixing protrusion 33 and the first fixing hole 24 are accurately aligned, appropriate pressure is applied to fully insert the protrusion into the hole, thereby achieving reliable fixing of the backlight support frame 3 to the support frame 2.

[0048] Furthermore, the touch display component 1 includes a touch module 11, a display component 12, and a backlight component 14 stacked vertically. The touch module 11 and the display component 12 are stacked vertically on a support frame 22. The backlight component 14 is placed below the support frame 22 and fixed to the bottom plate 31 of the support frame. The touch module 11 is a capacitive touch screen. The lower ends of the touch module 11 and the display component 12 are respectively led out by a first flexible circuit board 15 and a second flexible circuit board 16. After the first flexible circuit board 15 and the second flexible circuit board 16 are connected to the touch module 11 and the display component 12, their other ends are bent to the back of the bottom plate 31 of the support frame.

[0049] Furthermore, the lower end of the frame sidewall 21 is also provided with a frame clearance space 25 corresponding to the first flexible circuit board 15 and the second flexible circuit board 16, providing a natural transition bending channel for the first flexible circuit board 15 and the second flexible circuit board 16 to prevent compression damage.

[0050] Furthermore, the touch module 11 and the display component 12 are bonded and fixed together by a first adhesive layer 13, which is made of optical adhesive.

[0051] Furthermore, such as Figures 5-7 As shown, the display component 12 includes a first polarizer 121, a first glass sheet 122, a second glass sheet 123, and a second polarizer 124 stacked sequentially. The first glass sheet 122 and the second glass sheet 123 contain liquid crystal material. A control IC is provided at the lower end of the second glass sheet 123. One end of the second flexible circuit board 16 is connected to the control IC at the lower end of the second glass sheet 123, and the other end is bent to the back of the support frame base plate 31.

[0052] Furthermore, such as Figure 4As shown, the top protective structure is a panel fixing frame 4, which is fastened to the upper part of the support frame 2. The panel fixing frame 4 and the support frame 2 are fixed to each other by a second fixing component. Specifically, the panel fixing frame 4 is a hollow rectangular frame, which includes a fixing frame sidewall 42 and an annular limiting stop edge 41 extending inward from the upper end of the four sides of the fixing frame sidewall 42. The extension length of the limiting stop edge 41 exceeds the edge contour of the touch display component 1, forming an effective limiting and stopping structure.

[0053] Furthermore, the second fixing component includes a second fixing protrusion 23 and a second fixing hole 43. The second fixing protrusion 23 is disposed on the outer side of the frame sidewall 21, and the second fixing hole 43 is a through hole penetrating the fixing frame sidewall 42. The positions, shapes, and dimensions of the second fixing protrusion 23 and the second fixing hole 43 are matched. In use, first align the fixing frame sidewall 42 of the panel fixing frame 4 with the outer side of the frame sidewall 21 of the support frame 2, and then press down smoothly in the vertical direction. During this process, the second fixing protrusion 23 will be accurately inserted into the second fixing hole 43. When the two are fully engaged, a clear "click" sound will be emitted, indicating that the assembly is in place. This design not only realizes the quick combination and fixing of the panel fixing frame 4 and the support frame 2, but also forms a reliable limiting and fixing of the touch display component 1 through the limiting edge 41.

[0054] Furthermore, the display component 12 is fixed to the upper surface of the support frame 22 by a second adhesive layer 5, which can be double-sided tape or other conventional adhesive.

[0055] Furthermore, the lower surface of the limiting edge 41 is bonded and fixed to the upper end of the skeleton sidewall 21 and the touch module 11 through the third adhesive layer 6. The third adhesive layer 6 can be adhesive foam or other conventional adhesive buffer material.

[0056] Furthermore, the back of the support frame base plate 31 is also provided with several pre-embedded nuts 34 for connection with an external host, simplifying the assembly process of the terminal product and improving production efficiency.

[0057] The preparation and assembly process of the reinforced touch display module provided by this utility model is as follows: A pre-embedded nut 34 is installed on the back of the support frame base plate 31; thermally conductive adhesive is applied to the front of the support frame base plate 31 to prepare for the subsequent installation of the backlight assembly 14; the backlight support frame 3 is inserted into the support frame 2 with the bottom aligned; when the first fixing protrusion 33 approaches the first fixing hole 24, the process is paused, the alignment is checked, and pressure is continued until all the first fixing protrusions 33 are fully engaged in the corresponding first fixing holes 24, and a clear locking sound is heard; the second... Adhesive layer 5 is applied, and then the display component 12 is precisely placed, ensuring that the first flexible circuit board 15 and the second flexible circuit board 16 pass through the skeleton clearance 25 and bend according to the design path. Then, the touch module 11 is attached to the display component 12 through the first adhesive layer 13. After the third adhesive layer 6 is attached to the limiting edge 41, the panel fixing frame 4 is fastened to the support skeleton 2. The force is applied evenly to ensure that all the second fixing protrusions 23 are fully inserted into the corresponding second fixing holes 43, thus completing the assembly of the reinforced touch display module.
