- the liquid crystal display template 100 may include an array substrate 110 and a color filter substrate 120.
- the adhesive 300 is applied to the opposite pair of sides (ie, the left and right sides) of the liquid crystal display template 100 and the backlight module 200. On the outer surface.
- the width of the array substrate 110 is larger than the width of the color filter substrate 120 in a direction parallel to the A-A line. That is, the array substrate 110 extends beyond the color filter substrate 120 on the lower side.
- the peripheral region of the array substrate 110 wider than the color filter substrate 120 can serve as, for example, an FPC connection region or a driver IC bonding region. Since the FPC or the driver IC chip is generally opaque, the width of the frame on the lower side of the liquid crystal display module 50 is sensitive to the FPC connection area or the driver IC bonding area, and is insensitive to the use of the double-sided tape and the width of the double-sided tape. Therefore, as shown in FIGS. 5b and 5d, on the lower side, the double-sided tape 400 is applied between the array substrate 110 and the backlight module 200, thereby further improving the adhesive strength.
- the double-sided tape 400 has a width W which is not particularly limited.
- the double-sided tape 400 can also be applied between the array substrate 110 and the backlight module 200 on the upper side, as shown at the top of Figure 5b.
- the double-sided tape 400 on the upper side generally has a small width, for example, 0.8 mm, so that the width of the frame of the upper side is prevented from being too large.
- the width W of the double-sided tape 400 on the lower side can be large.
- FIGS. 5a, 5b, 5c only schematically show an example of an FPC connection area or a driver IC binding area.
- the FPC connection area or the driver IC bonding area may also be disposed on two adjacent sides of the liquid crystal display module 50.
- the present disclosure also provides a display device including any one of the liquid crystal display modules 20, 30, 40, 50 described above.
- the display device can be any product or component having a display function, such as a mobile phone, a tablet, a television, a display, a notebook computer, a digital photo frame, a navigator, and the like.
- a display function such as a mobile phone, a tablet, a television, a display, a notebook computer, a digital photo frame, a navigator, and the like.
- Other indispensable components of the display device are understood by those skilled in the art, and are not described herein, nor should they be construed as limiting the disclosure.
- the present disclosure also provides a method of fabricating a liquid crystal display module. As shown in the flowchart of FIG. 6, the method includes: step S10, applying an adhesive to an outer surface of at least one side of the liquid crystal display panel to be bonded and the backlight module; and step S20, curing the adhesive, Thereby, the liquid crystal display panel and the backlight module are fixed to form a liquid crystal display module.
- the method may further include: step S110, on the side of the liquid crystal display panel and the backlight module to which no adhesive is to be applied, in the liquid crystal display panel and the backlight module Apply double-sided tape between them.
- the liquid crystal display panel may include an array substrate and a color filter substrate
- step S110 may include applying a double-sided tape between the array substrate of the liquid crystal display panel and the backlight module.
- step S110 may include applying a double-sided tape between the array substrate and the backlight module on a side of the array substrate that extends beyond the color filter substrate.
- the adhesive can be a UV curable adhesive, a thermosetting adhesive, or a thermoplastic adhesive.
- the adhesive can be black.
- the thickness of the adhesive after curing may be from 0.05 to 0.5 mm.
- the present disclosure in the liquid crystal display module, at least one side of the liquid crystal display panel and the backlight module applies an adhesive on the outer surface, thereby achieving a firm bond therebetween. Since the liquid crystal display panel and the backlight module are bonded and fixed by the adhesive on the outer surface of the side, it is not necessary to use double-sided tape bonding. That is, the present disclosure provides an alternative to a double-sided tape that can achieve a strong bond between the liquid crystal display panel and the backlight module. Additionally, according to the present disclosure, since the double-sided tape is not used, the bezel width of the liquid crystal display module is no longer limited by the width of the double-sided tape, and the bezel width of the liquid crystal display module can be reduced by controlling the thickness of the glue.
