Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display modules, and particularly relates to a liquid crystal display module with buckles on the backlight. Background Technique

[0002] A liquid crystal display module usually consists of an LCD display module and a backlight module. The edges of the LCD display module and the backlight module are fixed by adhesive paste. Since the peripheral edge of the display screen of the liquid crystal display module tends to be narrower and narrower, the contact area for pasting between the LCD display module and the backlight module is getting smaller and smaller, and the adhesive force is insufficient, so the LCD display module and the backlight module are prone to falling off.

[0003] For example, a dust-proof liquid crystal display module of a Chinese utility model patent (CN206892496U) includes: a touch screen, an LCD polarizer, an LED backlight, and a glass substrate. The glass substrate is located between the touch screen and the LED backlight, and an LCD polarizer is arranged on one side of the touch screen close to the LED backlight; the surfaces of the LCD polarizer and the LED backlight are at the same height; the touch screen is pasted to the LCD polarizer and the LED backlight through double-sided adhesive. The double-sided adhesive is pasted inside the LCD polarizer, and the double-sided adhesive is in a square shape with a hole in the middle. Among the four side frames of the square shape with a hole in the middle, the distance between the inner frame edge of the double-sided adhesive and the outer shape edge of the LCD polarizer of the double-sided adhesive is equal, and the distance between the outer shape edge of the double-sided adhesive and the outer shape edge of the LCD polarizer of the double-sided adhesive is equal. Although this patent improves the dust-proof function of the liquid crystal module, it is not firm enough to fix the backlight and the glass substrate only through double-sided adhesive.

[0004] Therefore, it is necessary to continue to provide a liquid crystal display module with stable assembly of the LCD display module and the backlight module. Content of the Utility Model

[0012] Further, the inclined surface gradually thins after extending from the side edge of the backlight frame, and the clamping surface is perpendicular to the extended side edge and the bottom surface of the backlight frame.

[0013] Further, the bottom surface is embedded in the clamping groove, and the length of the clamping surface from the extended end of the backlight frame to the bottom surface is less than the concave depth of the clamping groove.

[0014] Further, the height h of the inclined surface at the extended end of the side edge of the backlight frame and the clamping surface at the extended end of the side edge of the backlight frame is equal to the sum of the thicknesses of the upper polaroid and the upper glass sheet.

[0048] Further, the liquid crystal display module further comprises a flexible circuit board 3, one end of the flexible circuit board 3 is connected to the control IC 131 and leads out, and the other end is connected to a PCB board to form a conduction circuit.

[0049] Further, the LCD fixing structure is snapped on the LCD display module 1, and specifically, the LCD fixing structure is a plurality of buckles 22 arranged on one side or multiple side edges of the backlight frame 2. The buckle 22 extends inward along the side edge of the backlight frame 2 to form.

[0050] In the embodiment, the buckle 22 is arranged on the side edge opposite to the leading-out edge of the flexible circuit board 3, and in the embodiment, the number of the buckle 22 is two, and in other embodiments, the arrangement position and number of the buckle 22 can be adjusted according to the size and structure of different liquid crystal display modules.

[0051] Further, the buckle 22 is a cuboid, a square or a right trapezoidal structure extending from the side edge of the backlight frame to the inner side of the embedding groove 21, which comprises a clamping surface 221 abutting and clamping the upper polarizer 11 of the LCD display module 1.

[0052] Embodiment 2

[0053] As Figures 5-10As shown, the embodiment provides a backlight snap LCD display module, which is different from the embodiment 1 in that the LCD fixing structure is snap with the inside of the LCD display module 1, and the edge of the LCD display module 1 adjacent to the LCD fixing structure is provided with a plurality of snap slots 15 matched with the LCD fixing structure. Specifically, the snap slot 15 is an arc-shaped avoidance slot structure formed by inwardly recessing along the edge of the upper polarizing plate 11 and the upper glass sheet 12, which is snap matched with the LCD fixing structure on one hand, and facilitates one-cut forming of the upper polarizing plate 11 and the upper glass sheet 12 on the other hand.

[0054] Further, the LCD fixing structure is snap with the LCD display module 1, and the LCD fixing structure is a plurality of snap buckles 22 provided on one side or multiple side edges of the backlight rubber frame 2. Specifically, the snap buckle 22 is a right-angled trapezoidal body structure formed by extending along the side edge of the backlight rubber frame 2 to the inside of the embedded groove 21.

[0055] Further, as shown, Figure 9 The cross section of the snap buckle 22 is a right-angled trapezoid, which includes a snap surface 221 and an inclined surface 222. Specifically, as viewed from the cross section, the snap surface 221 of the snap buckle 22 is a right angle of the right-angled trapezoid, and the snap surface 221 is snap matched with the lower glass sheet 14 of the LCD display module 1; the inclined surface 222 of the snap buckle 22 is an inclined side of the right-angled trapezoid, and further, the inclined surface 222 gradually thins after extending from the side edge of the backlight rubber frame 2. In use, the snap buckle 22 is snap into the snap slot 15, so that the backlight rubber frame 2 of the LCD display module 1 is fixed with each other.

[0056] Further, the snap buckle 22 further includes a bottom surface 223, and the snap surface 221 and the inclined surface 222 extend to the bottom surface 223 from the side edge of the backlight rubber frame 2 to the inside. The bottom surface 223 is embedded in the snap slot 15, and further, as viewed from the cross section, the length of the snap surface 221 of the snap buckle 22 from the extending end of the backlight rubber frame 2 to the bottom surface 223 is less than the recess depth of the snap slot 15, so as to prevent the snap buckle 22 from scratching the LCD display module 1. Further, the height h of the extending end of the inclined surface 222 at the side edge of the backlight rubber frame 2 and the extending end of the snap surface 221 at the side edge of the backlight rubber frame 2 is equal to the sum of the thicknesses of the upper polarizing plate 11 and the upper glass sheet 12, so that when the snap buckle 22 is snap into the LCD display module 1, the height of the snap buckle 22 is flush with the height of the LCD display module 1, and the snap buckle 22 does not protrude from the LCD display module 1, which is aesthetically pleasing on one hand, and is conducive to surface bonding of the protective cover plate of the LCD display module 1 on the other hand.

[0057] Further, as shown, Figure 10As shown, the buckle 22 is further provided with a groove 224 on both sides of the side edge of the backlight frame 2, so that the buckle 22 is flexible, and the assembly of the LCD display module 1 and the backlight frame 2 is facilitated. Specifically, the depth of the groove 224 on the side edge of the backlight frame 2 is equal to the height h of the extension end of the inclined surface 222 on the side edge of the backlight frame 2 and the extension end of the clamping surface 221 on the side edge of the backlight frame 2. Because the grooves 224 are arranged on both sides of the buckle 22, the LCD display module 1 can be embedded into the backlight frame 2 by slightly pulling the buckle 22 outward during assembly, so that more flexible space is reserved for assembly.
