Description
Technical field
The present invention relates to display technology field more particularly to a kind of face plate indicia method for detecting and face plate indicia regions
Mura compensation methodes.
Background technology
As liquid crystal display (Liquid Crystal Display, LCD) is sent out towards lighter, thinner, bigger direction
Exhibition, because of some uncontrollable factors on practical processing procedure, makes the physical characteristic of LCD display panel everywhere have differences, causes big
In the range of a pixel, when showing pure gray level image the phenomenon that brightness irregularities, i.e. so-called Mura phenomenons of industry.
Mura phenomenons have become the bottleneck for restricting LCD development.By improving technological level or improving material purity
The methods of can reduce the probability of happening of Mura phenomenons.For the LCD display panel to have completed, physical characteristic has been determined
Type, the Mura phenomenons generated to make up the flaw on LCD processing procedures, can correct picture by way of grey level compensation at this time
The brightness of vegetarian refreshments, and then improve Mura phenomenons.
Grey level compensation is to realize the improvement of brightness uniformity by changing the gray value of pixel：Shot by camera
Then the Mura situations of gray scale picture determine normal region and the regions Mura in gray level image, finally according to normal region
The gray value in the regions gray value Contrary compensation Mura applies the relatively high pixel of display brightness when showing pure gray level image
Add lower gray value, for the relatively low pixel of display brightness, apply higher gray value so that each pixel after grey level compensation
Brightness close to consistent, realize the improvement of Mura phenomenons.
Fig. 2 is please referred to Fig.1 and combines, in order to ensure that scratch, LCD not occur in process of production in LCD display panel 100
Transparent protective film is posted on the polaroid on 100 surface of display panel, but polaroid supplier can be had any different on protective film
Alphabetical spray printed mark (Mark), the Mark generally form (such as letter " ABC " in Fig. 1) by 2~3 individual letters, by
Then spray printing is to protection film surface at certain intervals distance, there are certain difference in size between letter, whole Mark
Size and location variation is larger, therefore, as shown in Figure 1, during detecting, it cannot be guaranteed that all letters can all occur
In the fixation detection region 101 of setting, such as alphabetical " C " is at outside fixed detection region 101 in Fig. 1, thus can not be by solid
Determine detection region 101 to Mark processing, if Mark exceeds detection region, can be judged as that Mura carries out luminance compensation,
After client tears protective film, as shown in Fig. 2, positions (position of alphabetical " C ") of the Mark beyond detection region just has speck shape
At causing 100 quality of LCD display panel bad.

The position of complete mark group 20 on LCD display panel 1, and stop the detecting to marking unit 21；
Step 6 does analogue data calculating for the position of each marking unit 21 in the mark group 20 recorded in step 5, really
The Mura offset datas for determining 21 region of each marking unit in mark group 20, to 21 institute of each marking unit in the mark group 20
Region carry out Mura compensation.
Particularly, the strain detection region 30 being arranged in the step 4 is with the position of the part marking unit 21 detected
Centered on the region put；The distance at central point to its edge of the strain detection region 30 is more than the whole length of the mark group 20
Degree, determination detect complete mark group 20, prevent from causing LCD display panel to be mended through Mura because the detecting of mark group is imperfect
Occurs the case where hickie after repaying.
Further, the step 6 specifically includes：Each marking unit 21 in mark group 20 on acquisition LCD display panel 1
The Mura offset datas of position surrounding, interpolation calculation go out 21 location of each marking unit in the mark group 20 of the LCD display panel 1
The Mura offset datas in domain carry out Mura compensation to the region where each marking unit in the mark group 20 21.
In conclusion the face plate indicia method for detecting of the present invention, the first position according to mark group on LCD display panel
One fixed detection region is arranged to detecting board, makes the detecting board in fixed detection region to the label on LCD display panel
Unit is detected, if the detecting board detects the part marking unit in mark group, according to the detecting board root
A strain detection region is reset according to the part marking unit detected, the detecting board is aobvious to LCD in the strain detection region
Show that panel is detected again, make the detecting board in the strain detection region detects mark group whole marking units to detect
Measure complete mark group, the detecting board is to whole marking units in the mark group that detects on LCD display panel
Position is recorded, so that it is determined that the band of position of complete mark group, using the method for detecting in the position area to mark group
When domain carries out Mura compensation, it can be ensured that the LCD display panel region that mark group is blocked after Mura is compensated will not form different
Normal hickie；The Mura compensation methodes in the face plate indicia region of the present invention, it is first determined the band of position of complete mark group, then needle
Mura compensation is carried out to the band of position of the complete label group, it can be ensured that LCD display panel mark group institute after Mura is compensated
The region blocked will not form abnormal hickie.
The above for those of ordinary skill in the art can according to the technique and scheme of the present invention and technology
Other various corresponding change and deformations are made in design, and all these change and distortions should all belong to the claims in the present invention
Protection domain.
