The invention also provides a kind of method of inspection of above-mentioned filth test device, comprise the following steps：
Step 1, the display of backlight module is put into locating slot up；
Step 2, transparent plastic mulching on the display surface of backlight module；
Step 3, start pneumatic means, by hyaline membrane absorption on check-out console, hyaline membrane is compressed on the display surface of backlight module,
The power connection end of backlight module contacts connection with electrode slice, lights backlight module；
Step 4, hyaline membrane is visually observed, if not observing foreign matter, backlight module is qualified；If it was observed that foreign matter, backlight module
It is unqualified, carry out step 5；
Step 5, it will verify that the backlight module that foreign matter be present is reprocessed.
Preferably, rolled and applied on hyaline membrane by soft roller after hyaline membrane absorption is on check-out console in step 3
Pressure.
Compared with prior art, the present invention has advantages below：
1st, pressure is applied to backlight module by using hyaline membrane, amplifies the foreign matter area on its surface, help inspector to examine
Into backlight module, naked eyes are sightless, have the bad foreign matter of certain volume, reduce the fault rate of backlight module, reduce and reprocess
Cost；
2nd, being coordinated using stomata and pneumatic means makes the stable absorption of hyaline membrane on check-out console, the bad display stabilization of foreign matter, will not
Because of removing for the pressure pieces such as roller so that membrane material relaxation influences foreign matter and shown.
