VERSION: 2 PAGE: 16
L
d=(w+l)/2
Notes：
1.It is prohibited to have 5 areas of dot or line defects, and the distance between each other should
≥5mm.
2.VA area is 5000mm²,which apply to 4~4.5inches,and it is for 20 modules. 600mm² is for 1.4inches
of 200 modules.
Once area of VA exceeds 20000mm²(about 8inches, 6modules),it needs to redefine standard of dot
and line.
