Embodiment

Below, enumerate preferred embodiment of the present utility model now, and cooperate the following graphic back that is described in more detail in:

See also Fig. 3 and shown in Figure 4, it is first preferred embodiment of a kind of LCD MODULE of the utility model, and this LCD MODULE 100 comprises:

One liquid crystal display 10, this liquid crystal display 10 includes a framework 12, and this framework 12 forms one first 14 and 1 second 16 and one lateral surface 18 that is located in periphery respectively in two big faces;

One metal frame 20; this metal frame 20 is fixed on this framework 12; and can protect framework 12 and have the effect of static electricity prevention and curing (electrostatic discharge); this metal frame 20 is combined into this LCD MODULE 100 with this liquid crystal display 10; and this metal frame 20 generally is the L type; and form one first sheet metal 22 and one second sheet metal 24; this first sheet metal 22 is near the lateral surface 18 that is fixed in this framework 12; and this first sheet metal 22 is provided with one first opening 221; this second sheet metal 24 has a plurality of pilot holes 241; those pilot hole 241 correspondences are fixed in the trip (figure does not show) of 12 first 14 of this frameworks; be incorporated into this liquid crystal display 10 for these second sheet metal, 24 secure; and this second sheet metal 24 has two breach 242; 243, and this second sheet metal 24 is formed with end 244 and one earth terminal 245 of feeding respectively in the both sides of this breach 242.

Please cooperate Fig. 5 and shown in Figure 6 again; when LCD MODULE 100 is finished in follow-up assembling; the non-display surface of this LCD MODULE 100 is to be located at a printed circuit board (PCB) (Printed CircuitBoard; PCB) 200 tops; and second sheet metal 24 of metal frame 20 faces printed circuit board (PCB) 200; this printed circuit board (PCB) 200 has two metal pilot pins 201; 202; this two metals pilot pin 201; 202 are subjected to the pushing tow of a spring 203 respectively; making the top keep respectively with feed end 244 and earth terminal 245 contacts; that is printed circuit board (PCB) 200 is electric connection with metal frame 20; by this; metal frame 20 not only possesses the effect of protection framework 12 and static electricity prevention and curing; more because of its end 244 of feeding uses with output as the feed-in of current signal, its earth terminal 245 uses as ground connection, makes metal frame 20 have the function that receives communication frequency.
