Description
Technical field
The present invention relates to liquid crystal display production technical fields, more particularly to a kind of preceding two-in-one mould group of fitting to prevent fitting deviation
Detection method.
Background technique
As the rapid development and terminal client of mobile phone industry are to the requirements at the higher level of mobile phone display effect, mobile phone is aobvious at present
Show mould group and touch-control TP or the most of all practical technique being bonded entirely of cover board.During production testing, it need to ensure display module
Fitting cannot be deviated more than design tolerance entirely with LENS (lens), and otherwise display screen display area can be hidden by the display window of LENS
Gear causes to show imperfect.
There are two types of current major part LCM manufacturer production testing modes, and one is aobvious by sampling observation LCD after full fitting
Show region and touch-control TP or cover board display area apart from size, judged with Quadratic Finite Element measurement fitting whether deviation, if exceed
Design requirement size, tolerance；.And use measuring speed if the mode of dimensional measurement slow, need to measure the multiple positions of product
Size, and measurement data is compareed with design size to determine whether deviation.This method formality is cumbersome, and product can only be taken out
Inspection cannot achieve full inspection, not can guarantee 100% qualification of factory properties of product, has missed detection risk, if there is tune machine mistake or life
During production machine it is unstable causes fitting deviation, had resulted in when inspecting discovery by random samples it is bulk bad, lose it is more serious；And for
(display area surrounding is the notch screen that U-type groove is opened in the angle R, the angle C product and display area to currently popular abnormal shape display products
Deng), display area is irregular arc, measures extremely difficult, inefficiency influence production capacity.
Another method is to observe whether display has an exception by showing picture in display module, but due to fitting
Tolerance is generally 0.1 millimeter or so, and Anawgy accuracy requires high, and in face of smaller bad of offset dimensions, naked eyes are more difficult to be discovered,
The effect of bad interception is not had.
Therefore, the prior art is defective, needs to improve.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of to be bonded two-in-one mould group entirely and prevent fitting deviation
Detection method, comprising: step 1: providing the CAD diagram paper of LCD and CG (cover-plate glass), determines LCD-AA (LCD visible area after fitting
Domain) and (cover-plate glass visible area) relative position CG-AA and according to design tolerance determine fitting after CG excursion limit position；
Step 2: the display pixel point on the LCD in extreme position boundary is determined according to CG excursion limit position；
Step 3: providing the test picture of a blank screen white edge frame, the test picture corresponds to the picture on the extreme position boundary
Vegetarian refreshments is white, and rest of pixels point is black；
Step 4: display module to be tested shows the test picture, observes in the test picture shown in display module
Whether white edge frame has missing, to judge whether fitting occurs deviation.
Further, the test picture is formed using picture making software development.
Further, the picture making software is Photoshop.
Further, the step 4 includes: step 4.1: the picture being converted to code, the code is increased to
In software test program；
Step 4.2: software test program being directed into detection device, the detection device drives display module to be detected aobvious
Show the test picture；
Step 4.3: whether white edge frame has missing in the test picture shown in observation display module, to judge to be bonded
Whether deviation is occurred.
Further, in the step 4.3, when white edge frame generation deficient phenomena in the picture observed, then determine to be bonded
Deviation occurs；When there is no deficient phenomenas for white edge frame in the picture observed, then it is qualified to determine to be bonded.
Using the above method, the present invention is simply easily operated, can with intuitive judgment whether deviation, save the cost and time,
It can be realized to the fitting undesirable full inspection of deviation, substantially increase the undesirable recall rate of fitting, be conducive to promote yields and visitor
Family satisfaction.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Referring to Fig. 1, the present invention provides and a kind of be bonded two-in-one mould group entirely and prevent fitting deviation detection method, comprising:
Step 1: the CAD diagram paper of LCD and CG being provided, determines the relative position LCD-AA and CG-AA and according to design after fitting
Tolerance determines the CG excursion limit position after fitting.
Step 2: the display pixel point on the LCD in extreme position boundary is determined according to CG excursion limit position.
Step 3: providing the test picture of a blank screen white edge frame, the test picture corresponds to the picture on the extreme position boundary
Vegetarian refreshments is white, and rest of pixels point is black.
The test picture is formed using picture making software development.The picture making software is Photoshop.
Step 4: display module to be detected is shown in the test picture shown in test picture observation display module
Whether white edge frame has missing, to judge whether fitting occurs deviation.
Wherein, the step 4 includes: step 4.1: the picture being converted to code, the code is increased to software
In test program；
Step 4.2: software test program being directed into detection device, the detection device drives display module to be detected aobvious
Show the test picture；
Step 4.3: whether white edge frame has missing in the test picture shown in observation display module, to judge to be bonded
Whether deviation is occurred.
In the step 4.3, when white edge frame generation deficient phenomena in the picture observed, then determine that deviation occurs for fitting；
When there is no deficient phenomenas for white edge frame in the picture observed, then it is qualified to determine to be bonded.
In conclusion the present invention is simply easily operated, can with intuitive judgment whether deviation, save the cost and time, can
It realizes to the fitting undesirable full inspection of deviation, substantially increases the undesirable recall rate of fitting, be conducive to promote yields and client is full
Meaning degree.
The above is merely preferred embodiments of the present invention, be not intended to restrict the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
