Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, and more specifically, to a liquid crystal display screen that prevents adhesive seepage. Background Technology

[0002] To ensure product structural stability, LCD display modules are typically designed with an upper metal frame. However, this upper metal frame creates an extra layer between the display module and the touchscreen, making full bonding between them extremely difficult. Conventional solid adhesive solutions cannot be used; instead, liquid optical adhesive must be employed. However, liquid optical adhesive is prone to leaking into the display module through the gap between the upper metal frame and the display module, leading to abnormal LCD display and reducing the product's competitiveness.

[0024] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] This utility model provides a liquid crystal display screen for preventing adhesive seepage, comprising a lower frame, a backlight module, a display module, an upper frame, high-viscosity sealant, and a cover plate. The lower frame includes a base plate and a side wall extending upward from the edge of the base plate. The backlight module is disposed above the base plate. The display module is disposed above the backlight module and includes a lower polarizer, a TFT module, and an upper polarizer stacked sequentially from bottom to top. The upper frame includes a top plate and a side plate extending downward from the edge of the top plate. The top plate is disposed above the upper polarizer, and the side plate is disposed outside the side wall and fastened to the side wall. The high-viscosity sealant is disposed between the upper polarizer and the top plate. The cover plate is disposed above the top plate and is bonded and fixed to the upper polarizer and the top plate by liquid optical adhesive.

[0026] Because a high-viscosity sealant is installed between the upper polarizer and the top plate, the high-viscosity sealant can seal the gap between the upper polarizer and the top plate, preventing liquid optical adhesive from leaking into the display module from the gap between the upper iron frame and the display module, thereby avoiding abnormal display of the LCD screen and improving the competitiveness of the product.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] Example 1, please refer to Figure 1This invention provides a liquid crystal display screen for preventing glue seepage, comprising a lower frame 1, a backlight module, a display module 2, an upper frame 3, a high-viscosity sealant 4, and a cover plate 5. The lower frame 1 includes a base plate 11 and a side wall 12 extending upward from the edge of the base plate 11. The backlight module is disposed above the base plate 11. The display module 2 is disposed above the backlight module and includes a lower polarizer 21, a TFT module 22, and an upper polarizer 23 stacked sequentially from bottom to top. The upper frame 3 includes a top plate 31 and a side plate 32 extending downward from the edge of the top plate 31. The top plate 31 is disposed above the upper polarizer 23, and the side plate 32 is disposed outside the side wall 12 and fastened to the side wall 12. The high-viscosity sealant 4 is disposed between the upper polarizer 23 and the top plate 31. The cover plate 5 is disposed above the top plate 31 and is bonded and fixed to the upper polarizer 23 and the top plate 31 by liquid optical adhesive 6. Because a high-viscosity sealant 4 is provided between the upper polarizer 23 and the top plate 31, the high-viscosity sealant 4 can seal the gap between the upper polarizer 23 and the top plate 31, preventing the liquid optical adhesive 6 from leaking into the display module 2 from the gap between the upper iron frame 3 and the display module 2, thereby avoiding abnormal display of the liquid crystal display screen and improving the competitiveness of the product.

[0029] Furthermore, a touch module 7 is provided on the lower surface of the cover plate 5. In this embodiment, the touch module 7 is a touch film. The touch module 7 below the cover plate 5 is bonded and fixed to the upper polarizer 23 and the top plate 31 by liquid optical adhesive 6.

[0030] Furthermore, since the liquid optical adhesive 6 is prone to overflow, in this embodiment, a frame adhesive 8 is provided between the touch module 7 and the upper iron frame. The frame adhesive 8 is located in the non-visible area and surrounds the visible area. The frame adhesive 8 blocks the liquid optical adhesive 6 to prevent the liquid optical adhesive 6 from overflowing.

[0031] Example 2, please refer to Figure 2 As a further optimization of Embodiment 1, in this embodiment, an anti-fingerprint film 9 is provided on the upper surface of the cover plate 5, so that users can avoid fingerprints remaining on the surface of the cover plate 5 during use, thereby improving the aesthetics of the LCD screen and enhancing the competitiveness of the product.

[0032] Furthermore, the thickness of the anti-fingerprint film 9 is 1μm to 10μm.

[0033] Furthermore, a surface treatment layer for improving surface roughness is provided on the upper surface of the cover plate 5 located in the non-visible area. The surface treatment layer is either a frosted layer or an etched layer. An adhesive layer is provided on the lower surface of the anti-fingerprint film 9 located in the non-visible area, so that the anti-fingerprint film 9 can be more firmly adhered to the upper surface of the cover plate 5. More preferably, the thickness of the adhesive layer is 0.5 μm.
