Embodiment mono-
The present embodiment provides a kind of detection display to shield the method for anti-stress ability, and the method comprises the following steps:
Step S1: make display screen to be detected in driving condition not, described display screen surface is carried out to the vacuum suction of Preset Time.
Display screen is carried out in the process of vacuum suction, on display screen, adsorption site place continues to be subject to effect of stress, and this can cause the thick box that is greater than gradually the region not being adsorbed of the box of liquid crystal cell at this place thick.
In the present embodiment, display screen to be detected can be the display screen of the polaroid of having fitted, and also can be the display screen of the polaroid of not fitting.
Display screen is carried out vacuum suction duration to (being Preset Time) and do not limit, this Preset Time preferably can be determined the quality requirements standard of display screen according to reality.Because Preset Time is longer, represent that display screen is subject to time of stress longer, the box of display screen liquid crystal cell is thick more easily produces more obviously and changes, if therefore stricter to the quality requirements of display screen, what Preset Time can suitably be set is longer, if be not very high to the quality requirements of display screen, the shortening that Preset Time can be suitable.Provide the preferable range of a Preset Time at this: 5 seconds～10 seconds, this scope can comprise endpoint value.
In addition, in the present embodiment, the quantity of the adsorption site that carries out vacuum suction is not limited, the adsorption site of the vacuum suction of each display screen can be one or more, is preferably one.And the position on display screen of adsorption site can be determined according to actual conditions, strictly do not limit, for guaranteeing the stable of absorption, adsorption site preferably can be near the center of display screen or center.
It should be noted that the adsorption plane of the display screen one side that preferably display screen shows.
Step S2: add up after described vacuum suction finishes the time that the color spot on described display screen disappears.
Because vacuum suction causes the thick region not being adsorbed that is greater than of adsorption site place box, make the refractive index of the light that penetrates liquid crystal cell adsorption site place be different from the refractive index of the light in the region not being adsorbed, therefore, after absorption finishes, can occur color spot at display screen adsorption site place, this color spot can be replied disappearance along with the bounce-back of adsorption site place liquid crystal cell.
The bounce-back recovery capacity of liquid crystal cell directly reflects the anti-stress ability of display screen.The die-out time of color spot is shorter, illustrates that the bounce-back recovery capability of liquid crystal cell is stronger, and the anti-stress ability of display screen is stronger; The die-out time of color spot is longer, illustrates that the bounce-back recovery capability of liquid crystal cell is poorer, and the anti-stress ability of display screen is poorer.Therefore, in the present embodiment, adsorb and finish the time that on rear display screen, color spot disappears by statistics, can judge the power of learning the anti-stress ability of display screen.
The time disappearing for adding up more accurately color spot, after being preferably in vacuum suction and finishing, carry out immediately the statistics of color spot die-out time, concrete statistical does not limit in the present embodiment, as: can be by staff's visual observations statistics.
It should be noted that, for the display screen that does not paste polaroid, before statistics color spot die-out time, need to place respectively upper and lower two polaroids in the upper and lower surface of display screen, and make the absorption axes of two polaroids mutually vertical, to the color spot on display screen is observed.For the display screen that has pasted polaroid, finish in absorption, display screen can directly be observed display screen after separating from vacuum slot, the time that statistics color spot disappears.
Step S3: the threshold value of the time that the time that more described color spot disappears and color spot disappear, if the time that described color spot disappears is less than or equal to described threshold value, judge that the anti-stress ability of described display screen is qualified, otherwise, judge that the anti-stress ability of described display screen is defective.
Filter out the satisfactory display screen of anti-stress ability, need for screening established standards: the threshold value of color spot die-out time.The threshold value of this color spot die-out time represents the satisfactory minimum of the anti-stress ability of display screen, when the color spot die-out time obtaining when actual count is greater than this threshold value, the anti-stress ability that judges display screen is defective, when the color spot die-out time obtaining when actual count is less than or equal to this threshold value, the anti-stress ability that judges display screen is qualified, thereby filters out satisfactory display screen.
It should be noted that, the threshold value of the time that the present embodiment disappears to color spot does not limit, and can determine the requirement of the anti-stress ability of display screen according to reality.If the requirement to the anti-stress ability of display screen is stricter, Threshold less of the time that color spot can be disappeared; If be not very high to the requirement of the anti-stress ability of display screen, Threshold higher of the time that color spot can be disappeared.In the present embodiment, the threshold value of the time that color spot disappears preferably can be less than or equal to 10 seconds.
The detection display that the present embodiment provides shields the method for anti-stress ability, and by the display screen not driving is carried out to vacuum suction, the die-out time of the color spot that statistics absorption forms, filters out the strong display screen of anti-stress ability.Because the anti-stress ability of display screen is stronger, in the process of follow-up and touch-screen laminating, be more not easy to occur to cause that by local pressure inequality touch-control that the thick variation of box causes shows the problem of module picture disply inequality, therefore in the present embodiment by filtering out in advance the stronger display screen of anti-stress ability, effectively reduce after the full laminating of display screen and touch-screen, there is the probability of the problem of picture disply inequality, greatly reduced the waste of the cost that causes module to scrap to cause due to picture disply inequality.
In addition, in the present embodiment by the display screen filtering out for the full laminating of touch-screen, for the underproof display screen of anti-stress ability, can be used for carrying out frame subsides with touch-screen, i.e. mouthful word glue laminating.The position of pasting due to frame is only in the frame region of display screen, therefore the stress in laminating process can't affect the viewing area of display screen, the box thickness ununiformity that the viewing area of display screen there will not be unbalance stress to cause, thereby in the present embodiment, because the anti-stress of which display screen of cicada is defective in advance, and the corresponding mode that adopts frame to paste when with touch screen combination, even if finally make touch-control show that module has adopted the underproof display screen of anti-stress ability, also can avoid to a certain extent the problem of the picture inequalities such as the caused demonstration macula lutea of box thickness ununiformity, further reduce and shown that the probability of the problem of picture disply inequality appears in module, effectively save cost.
