Title: Liquid crystal display module fixing structure

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the field of liquid crystal displaying, and in particular to a liquid crystal display module fixing structure. 
     2. The Related Arts 
     Liquid crystal displays (LCDs) have a variety of advantages, such as thin device body, low power consumption, and being free of radiation, and are thus of wide applications, including mobile phones, personal digital assistants (PDAs), computer screens, and notebook computer screens. 
     Most of the liquid crystal displays that are currently available in the market are backlighting liquid crystal displays, which comprise a backlight module, a liquid crystal panel coupled to the backlight module, and a bezel that fixes the liquid crystal panel and the backlight module. 
     The principle of operation of a liquid crystal panel is that with liquid crystal molecules interposed between two parallel glass substrates and a number of vertical and horizontal tiny electrical wires arranged between the two glass substrates, application of electricity is made to control the liquid crystal molecules to change direction in order to refract out the light emitting from the backlight module for generation of images. Since the liquid crystal panel itself does not emit light, light must be provided from the backlight module in order to normally display images. The backlight modules can be classified in two types, namely a side-edge backlight module and a direct backlight module, according to the site where light gets incident. The side-edge backlight module comprises an LED (Light-Emitting Diode) light bar, serving as a backlight source, which is arranged at an edge of a backplane to be located rearward of one side of the liquid crystal panel. The LED light bar emits light that enters a light guide plate (LGP) through a light incident face at one side of the light guide plate and is projected out of a light exit face of the light guide plate, after being reflected and diffused, to pass through an optic film assembly so as to form a planar light source for the liquid crystal panel. 
     As shown in  FIG. 1 , in the conventional liquid crystal display modules, a bezel  100  is often arranged to fix a liquid crystal display panel. When the modules have been shipped to a client side, a television front housing will be additionally assembled thereto. For a liquid crystal television product, the television front housing also provides a function of fixing the liquid crystal display panel. With such an arrangement, the module bezel  100  becomes a part that can be omitted. However, when the modules are to be shipped, without being fixed by the front bezel  100 , no secured shipment of the modules can be achieved. If the liquid crystal display panel and the backlight module of the module are shipped separately, an increase of expenses of packaging and transportation will result. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a liquid crystal display module fixing structure, which has the advantages of efficient assembling and dismounting and is useful for fixing a liquid crystal display module for substitute of a bezel to achieve the purpose of omitting the bezel. The fixing structure can realize fixation of the liquid crystal display module and ensure the security of the liquid crystal display module during shipment. 
     To achieve the above object, the present invention provides a liquid crystal display module fixing structure, which is provided for fixing a liquid crystal display module, wherein the liquid crystal display module comprises two side surfaces formed on two side edges thereof and two end surfaces formed on two end edges thereof.

The two second fixing sections of each of the second fixing pieces are respectively positioned against side faces of the two sides of the liquid crystal display module. The first fixing pieces press down against the second fixing pieces so as to fix the second fixing pieces to the liquid crystal display module. 
     The liquid crystal display module comprises a backplane. The backplane is provided with threaded holes for mounting a bezel. The bolts that extend through the first through holes threadingly engage the corresponding threaded holes of the backplane. 
     The first mounting sections each comprise a first cushion member to provide a cushioning effect when positioned on the liquid crystal display module. The first cushion member is located at the same side of the first mounting section as the first fixing sections are. The second mounting sections are each provided with a second cushion member to provide a cushioning effect when positioned on the liquid crystal display module. The second cushion member is located at the same side of the second mounting section as the second fixing sections are. 
     The first cushion member is made in the form of an elongate strip and is mounted, through adhesive bonding, to a middle portion of the first mounting section. The second cushion member is made in the form of an elongate strip and is mounted, through adhesive bonding, to a middle portion of the second mounting section.
