DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiments of the invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown.

FIG. 2 is a schematic view of a connecting assembly in accordance with one embodiment. The connecting assembly 6 includes a body 60, step surfaces 63, a positioning pillar 61 for a front frame, and a buffering component 62 arranged at a lateral side of the body 60.

The body 60 is substantially sheet-shaped. The body 60 may be a metallic sheet, or may be made by die casting or extrusion.

Two ends of the body 60 are bent downward and are extended outward so as to form the two step surfaces 63. The step surfaces 63 are substantially parallel to the body 60.

The positioning pillar 61 arranged on the body 60 extrudes out an up surface of the body 60. The step surfaces 63 include U-shaped holes 630.

The body 60 includes a through hole 600.

FIGS. 3-8 are schematic views of the connecting assembly 6 in accordance with one embodiment. The liquid crystal module includes a back plate 1 having at least a vertical plate, a backlight source 2 arranged at an internal side of the vertical plate, a liquid crystal glass 3, a plastic frame 4, the connecting assembly 6, a bolt 7, and the front frame 9.

The plastic frame 4 is arranged on a top of the vertical plate of the back plate 1 for supporting the liquid crystal glass 3. A rim of the liquid crystal glass 3 is covered by the black matrix.

The connecting assembly 6 is arranged above the plastic frame 4. The buffering component 62 of the connecting assembly 6 abuts against an edge of the liquid crystal glass 3 so as to protect the liquid crystal glass 3. In addition, the connecting assembly 6 is assembled with the plastic frame 4 by passing the bolt 7 through the U-shaped hole 630. It is to be understood that corresponding screw holes are arranged on the plastic frame 4. As the length of the U-shaped hole 630 is defined, the engaging location of the U-shaped hole 630 and the bolt 7 may be adjusted by changing the location of the bolt 7 within the U-shaped hole 630. As such, the relative locations between the connecting assembly 6, the plastic frame 4, and the vertical plate of the back plate 1 are adjustable. Furthermore, the relative location between the connecting assembly 6 and the liquid crystal glass 3 is adjustable. In one embodiment, the bolt 7 not only passes through the U-shaped hole 630, but also passes through the plastic frame 4 so as to engage with one blind hole 10 on an edge portion of the vertical plate of the back plate 1.

The front frame 9 arranged above the connecting assembly 6 is fixed with the connecting assembly 6. The front frame 9 covers the rim of the liquid crystal glass 3. Specifically, the front frame 9 includes a positioning hole 91 and a screw hole 90. The positioning hole 91 is for being passed through by the positioning pillar 61 of the connecting assembly 6 so that the front frame 9 is positioned on the connecting assembly 6. The screw hole 90 engages with the through holes 600 of the connecting assembly 6. The front frame 9 and the connecting assembly 6 are fixed together by passing the bolt 8 through the screw hole 90 of the front frame 9 and through the through hole 600 of the connecting assembly 6.

In view of the above, the connecting assembly 6 is arranged between the liquid crystal glass 3 and the front frame 9. The connecting assembly 6 adjusts the location of the bolt 7 within the through hole 600 so as to adjust the engaging location of the liquid crystal glass 3 and the plastic frame 4. The connecting assembly 6 and the front frame 9 are positioned by the positioning pillar 61 and are fixed by the bolt 8. That is to say the relative location of the front frame 9 and the connecting assembly 6 is fixed, and that of the connecting assembly 6 and the liquid crystal glass 3 is adjustable. In this way, the relative location of the front frame 9 and the liquid crystal glass 3 is adjustable so that the displacement of the display area of the liquid crystal panel is avoided. In other words, the display area and the exposed black matrix shown in FIG. 6 remain consistent.

In other embodiments, a liquid crystal display includes the above liquid crystal module in FIGS. 2 to 8.

The connecting assembly is arranged between the liquid crystal panel and the front frame so that the relative location of the front frame and the liquid crystal panel is adjustable. In addition, the displacement of the display resulting from the assembly errors is avoided. In this way, the display area and the black matrix of the liquid crystal module remain consistent.

It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
