Preferably, " the determining failed areas according to failpoint " in step 120 includes following two modes.
The first realization method：Distinguished using the line between any two failpoint in all failpoints as diagonal line
A rectangular area is determined, using the rectangular area including all failpoints as failed areas, for example, by apart from farthest two
Line between a failpoint determines a rectangular area as diagonal line, and the rectangular area includes all failpoints,
Then using the rectangular area as failed areas.
Second of realization method：Distinguished using the line between any two failpoint in all failpoints as diameter true
A border circular areas is made, using the border circular areas including all failpoints as failed areas.
It follows that failed areas can be just confirmed as by only containing the rectangle of all failpoints or border circular areas,
To ensure that the accuracy of determining failed areas.
Preferably, " effective coverage that display screen is determined according to failed areas " in step 130 mainly can be by following
Two ways is realized：
First way " determines display screen in step S130 when failed areas is rectangular area according to failed areas
Effective coverage " include：It is corresponding horizontally and vertically to obtain all boundaries of the failed areas in display area；One by one with every
Horizontal axis and every longitudinal axis are that display area is divided into two regions by dividing line, are individually identified as defective region and selection region,
The region for wherein including failed areas is defective region, and the region for not including failed areas is selection region；Obtain each selection
