W : Width(mm)
L : Length(mm)
D : Average diameter(mm)
Note) Those extraneous substances which can be wiped out easily are acceptable.
c) Display-on Inspection(Visual inspection)
i) Dot Defect
- Bright Dot Defects : When the LCM is turned on, dots(sub-pixels) which appear bright in the display
area at Black(Dark) Mode are bright dot defects.
R, G or B 1 dot
: 6 Max.
R, G or B join 2 dots : 1 Max.
R, G or B join 3 dots : 0 max.
Minimum Distance between defects : D 10mm
Total amount of Bright dot defects : 6 Max.
- Black Dot defects : When the LCM is turned on, dots(sub-pixels) which appear black in the display
area at White(Bright) Mode are black dot defects.
1 dot : 6 Max.
Join 2 dots : 1 Max.
Join 3 dots : 0 max.
Minimum Distance between defects : D 10mm
Total amount of Black dot defects : 6 Max.
- Total amount of Dot Defect(Bright and Black Dot) : 10 Max. (Combination)
ii) Line Defect
All line defects such as vertical, horizontal or cross line defect are not allowed.
Note 1) Dot Defect : Defected area > 1/2 dot
2) 1 Dot : Defect dot is isolated, not attached to other defect dot.
3) 3 Join N Dot : N dots are consecutive. (N means the number of defect dots)
9. Other
If any problems arise with the LCM supplied by LGE, the Customer and Supplier will cooperate and make
efforts to solve it with mutual confidence and respect.
