Gap be present between plate 011.
The detection process of liquid crystal filling amount detecting device comprises the following steps：
Step S1, referring to shown in Fig. 4 a, relief valve 30 is closed, the opening of the suction muffler 111 of sucker 10 is positioned over display
The detection zone of panel 010, sucker 10 is set to adsorb on display panel 010, in specific implementation, detection zone is normally at display
The intermediate region of panel 010.
Step S2, manually operated manual suction pump 20, is evacuated to the suction muffler 111 of sucker 10, and observes air gauge 40,
Stopped suction after pressure needed for reaching.Specifically, when one-handed performance is evacuated, the palm when held tracheae 50 of operating personnel is away from suction
One end of disk 10, finger gripping are stopped the drive end 61 of handle 60, bend finger back and forth to drive manual suction pump 20 to be evacuated.Ginseng
As shown in Fig. 4 b, under the suction-operated of sucker 10, the detection zone of display panel 010 produces protuberance, makes the box of the opening position
Thickness is more than other positions, and due to optical effect, display panel 010 is partially yellow in the higher opening position display image of box thickness, produces color
Poor problem.In specific implementation, as 11 a diameter of 15mm of disk body of sucker 10, absorption pressure is 50kpa.
Step S3, after adsorbed state to the certain time for keeping sucker 10, relief valve 30 is opened, while record display panel
The time that the aberration phenomenon of 010 detection zone disappears.By keeping the adsorbed state of sucker 10 to make display to certain time
The surface of panel 010 is fully adsorbed, and the time is specially the 10-20 seconds.After relief valve 30 is opened, the suction muffler of sucker 10
So as to stop the absorption to display panel 010, deformation caused by display panel 010 can fade away for air inlet in 111.Filled out in liquid crystal
Fill in not excessive display panel 010, certain bear can be formed inside it after array base palte 011 and the pairing of color membrane substrates 012
Normal condition can be quickly returned to after the adsorbed deformation of pressure condition, array base palte 011 or color membrane substrates 012.And in liquid crystal
Fill in excessive display panel 010, its internal negative pressure state is smaller, and array base palte 011 or color membrane substrates 012 recover normal shape
It is longer the time required to state.The time that array base palte 011 or color membrane substrates 012 recover normal condition is that the aberration of detection zone shows
As the time of disappearance, can be drawn by observation.
Step S4, the time that the aberration phenomenon of the detection zone for the display panel 010 measured disappears is entered with fiducial time
Row contrast, determine whether the liquid crystal loading of display panel 010 is excessive.Specifically, fiducial time is that liquid crystal loading is not excessive
Display panel 010 test zone aberration phenomenon disappear time, in specific implementation can by measurement draw.What is measured
When the time that the aberration phenomenon of the detection zone of display panel 010 disappears is more than fiducial time, then illustrate tested display panel 010
Liquid crystal filling it is excessive, and when the time that the aberration phenomenon of the detection zone in the display panel 010 measured disappears is less than benchmark
Between when, then illustrate that the liquid crystal filling of tested display panel 010 is not excessive.
By above-mentioned method of testing, the liquid crystal filling amount detecting device that the present embodiment provides can facilitate, and efficiently test out
Whether the liquid crystal in display panel 010 fills excess.
Obviously, those skilled in the art can to the utility model embodiment carry out it is various change and modification without departing from
Spirit and scope of the present utility model.So, if these modifications and variations of the present utility model belong to the utility model right
It is required that and its within the scope of equivalent technologies, then the utility model be also intended to comprising these change and modification including.
