Description
Technical field
The present invention relates to display technology field, and in particular to a kind of bearing calibration of curved face display panel and its system.
Background technology
As liquid crystal display (LiquidCrystalDisplay, LCD) develops towards lighter, thinner, bigger direction,
Because of some uncontrollable factors on actual processing procedure, the physical characteristic of LCD display panel everywhere is had differences, is caused more than one
In the range of individual pixel, the phenomenon of brightness irregularities when showing pure gray level image, i.e., the image deflects Mura alleged by industry shows
As.
Image deflects Mura phenomenons have become the bottleneck for restricting LCD development.By improving technological level or improving material
The methods of expecting purity can reduce the probability of happening of image deflects Mura phenomenons.For the LCD display panel to have completed, its
Physical characteristic has been shaped, the defects of being produced to make up the flaw on LCD processing procedures Mura phenomenons, can now pass through gray scale
The mode of compensation carrys out the brightness of correction pixels point, and then improves image deflects Mura phenomenons.
Grey level compensation is to realize the improvement of brightness uniformity by changing the gray value of pixel：Shot by camera
The defects of gray scale picture Mura situations, it is last according to just it is then determined that normal region and defect Mura regions in gray level image
The gray value in the gray value Contrary compensation defect Mura regions in normal region, when showing pure gray level image, for display brightness ratio
Higher pixel applies relatively low gray value, for display brightness than relatively low pixel, applies higher gray value so that gray scale
The brightness of each pixel realizes the improvement of image deflects Mura phenomenons close to unanimously after compensation.At present, curved surface LCD TV is increasingly
It is popular, but after panel (panel) is bent into curved surface state by flat state, the liquid crystal in it can be because by glass
Folding s tress extrudes and other unpredictable image deflects Mura occur (does not have, but new after bending under panel flat states
Increase), so defect Mura reparations can not be carried out under panel flat states, panel is then bent into curved surface, unique side
Method can only carry out defect Mura compensation under curved surface panel states and repair.
It is flat state that the image deflects Mura compensation restorative procedures of industry, which are all based on panel, because camera photographs
Display surfaces of the panel under flat state and curved surface state accumulate in difference, the plane length under curved surface state is less than plane
Plane length under state, so restorative procedure directly can not be compensated using existing plane picture defect Mura to calculate

Position in 111 is A points, if the radius of the circular arc is R, chord length b, then BC=b/2, then ∠ BOC=θ=arcsin [b/
(2R)], OB=x=R*cos θ=R*cos { arcsin [b/ (2R)] }, if AB=y, then ∠ AOB=α=arctan (y/x), institute
With arc length DE=z=arctan (y/x) R.Wherein, z is the girth using R as radius, using α as angle, so z=α × R, due to
Tan α=y/x, so α=arctan (y/x), that is, obtain z=arctan (y/x) R；Y is straight line AB length, i.e. compensation point exists
Position in the image 111 that optical sensor collects is to the distance of the vertical centerline of the image, x=R*cos { arcsin
[b/ (2R)] }, that is, obtain arc length DE and straight line AB correspondence position relation (point centered on B or D positions).
So, compensation point is found out in curved-surface display face by position of the compensation point on the image that optical sensor collects
Position on plate, then using the corresponding relation so as to which offset is reverted into correct position, so as to under curved surface state
Curved face display panel carry out correct image deflects compensation, improve the product quality of curved face display panel.
