Technical field
The utility model relates to the LCD MODULE of mobile phone, relates in particular to the antistatic liquid crystal display module of a kind of mobile phone.
Background technology
In recent years, along with the progress of science and technology, the development of society, mobile phone has got in the middle of people's the life and work, and is closely related with people's life; Mobile phone is in daily use, and the operate as normal of its LCD Panel is extremely important, like transmitting-receiving note, online etc.The LCD MODULE of present mobile phone is because the factor of its material and environment for use; Make the static that often has high voltage of LCD MODULE; A little less than the antistatic effect of the main control chip of LCD MODULE; Therefore static is harmful to the work of the main control chip of LCD MODULE, causes flower screen phenomenon through regular meeting, can cause main control chip so that LCD MODULE to work when serious.For eliminate or reduce LCD MODULE with static, the technological means that adopts at present has: 1, the data-interface ground of liquid crystal display screen end is held with the interface ground of cell phone mainboard; 2, the back side of liquid crystal display screen increases conducting adhesive cloth, is connected with the interface ground end of cell phone mainboard through conducting adhesive cloth.This dual mode mainly is through lead-in wire the static of LCD MODULE to be caused cell phone mainboard; If mobile phone is in long use; When in case lead-in wire loose contact or other factors cause the static of LCD MODULE not caused on the cell phone mainboard; The main control chip of LCD MODULE just has by the risk of electrostatic damage, and then causes mobile phone not use, and has influence on people's live and work.
Summary of the invention
The purpose of the utility model is to solve the deficiency of prior art; Provide a kind of mobile phone antistatic liquid crystal display module; The mode of this LCD MODULE through directly contacting; The static of LCD MODULE is caused cell phone mainboard, guarantee that LCD MODULE institute static electrification is less, the main control chip working stability of LCD MODULE.
The technical scheme that the utility model adopts is:
The antistatic liquid crystal display module of a kind of mobile phone comprises LCDs, is fixed on the main control chip and the flexible PCB at the LCDs back side; The upper end of said flexible PCB is electrically connected with LCDs; Said flexible PCB is provided with at least one sheet metal, and said sheet metal is held corresponding with the interface ground end of main control chip and the interface ground of cell phone mainboard respectively.
As preferably, the middle bottom of said flexible PCB is provided with the fixing glue that is used for flexible PCB is fixed in cell phone mainboard.
Further, said fixing glue is a double faced adhesive tape.
As preferably, the middle part of said flexible PCB is provided with three parallel sheet metals.
As preferably, said sheet metal is a copper sheet.
The described interface of the utility model ground end is the earth terminal of interface.
The beneficial effect of the utility model is: the antistatic liquid crystal display module of a kind of mobile phone comprises LCDs, is fixed on the main control chip and the flexible PCB at the LCDs back side; The upper end of said flexible PCB is electrically connected with LCDs; Said flexible PCB is provided with at least one sheet metal, and said sheet metal is corresponding with the interface ground end of main control chip and cell phone mainboard respectively.When the utility model uses; The bottom of flexible PCB is upwards turned up and is electrically connected with cell phone mainboard; After flexible PCB is upwards turned up; Sheet metal on the flexible PCB is between the interface ground of the interface ground of main control chip end and cell phone mainboard end, and promptly main control chip directly is electrically connected with the interface ground end of cell phone mainboard through sheet metal, after on the LCD MODULE generation of static electricity being arranged; Static on the main control chip directly causes the interface ground end of cell phone mainboard through sheet metal, can prevent effectively that static on the main control chip of LCD MODULE is excessive and influence main control chip and normally use.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation further.
Embodiment:
As shown in Figure 1, the antistatic liquid crystal display module of a kind of mobile phone comprises LCDs 1, is fixed on the main control chip 11 and the flexible PCB 2 at LCDs 1 back side; The upper end of said flexible PCB 2 is electrically connected with LCDs 1; Said flexible PCB 2 is provided with at least one sheet metal 21, and said sheet metal 21 is held corresponding with the interface ground end of main control chip 11 and the interface ground of cell phone mainboard respectively.
As shown in Figure 2; When the utility model uses; The upper end of flexible PCB 2 is electrically connected with the lower end of LCDs 1; The lower end of flexible PCB 2 is upwards turned up and is electrically connected with cell phone mainboard, and after flexible PCB 2 was upwards turned up, the sheet metal 21 on the flexible PCB 2 was between the interface ground of the interface ground of main control chip 11 end and cell phone mainboard end; Be that main control chip 11 directly is electrically connected with the interface ground end of cell phone mainboard through sheet metal 21; After on the LCD MODULE generation of static electricity being arranged, the static on the main control chip 11 directly causes the interface ground end of cell phone mainboard through sheet metal 21, can prevent effectively that static on the main control chip 11 of LCD MODULE is excessive and influences main control chip 11 and normally use.
