8) Stains on the surface of LCD
panel
9) Rainbow color
Scratches and dent on the polarizer shall be in the accordance
with “2) Black/white spot”, and “3) Black/White line”.
Stains which cannot be removed even when wiped lightly
with a soft cloth or similar cleaning.
No rainbow color is allowed in the optimum contrast on state within
the active area.

11) Bezel appearance
12) Defect of land surface
contact
Polarizer edge or line is visible in the opening viewing area due to
polarizer shortness or sealing line.
Rust and deep damages that are visible in the bezel are rejected.
Evident crevices that are visible are rejected.

matter (solder ball,
solder hips)
16) PCB pattern damage
17) Faulty PCB correction
18) Bezel flaw
19) Indication on name plate
(sampling indication label)
(1) Failure to mount parts
(2) Parts not in the specifications are mounted
(3) For example: Polarity is reversed, HSC or TCP falls off.
(1) LSI, IC lead width is more than 50% beyond pad outline.
(2) More than 50% of LSI, IC leads is off the pad outline.
(1) 0.45<Φ, N1
(2) 0.3<Φ≤0.45, N1
Φ: Average diameter of solder ball (unit: mm)
(3) 0.5<L, N1
L: Average length of solder chip (unit: mm)
(1) Deep damage is found on copper foil and the pattern is nearly
broken.
(2) Damage on copper foil other than 1) above
(1) Due to PCB copper foil pattern burnout, the pattern is
connected, using a jumper wire for repair;2 or more places
are corrected per PCB.
(2) Short-circuited part is cut, and no resist coating has been
performed.
Bezel claw missing or not bent
(1) Failure to stamp or label error, or not legible.(all acceptable if
legible)
(2) The separation is more than 1/3 for indication discoloration, in
which the characters can be checked.
