6.1.10
Pattern
distortion
The pattern displayed width is either wider ,
narrower or deformed than the specified, caused
by its misalignment and resulting in unwanted
heave(s) or missing:|Ia-Ib|≤1/4W(W is the normal
width
)
|Ia-Ib|>1/4W,
Reject
√
6.1.11
Voltage
When normally working the bias between
measured voltage and designed voltage is more
than ±4% (if at or below
5V, inspect at the tolerance
of +/-0.2V)
Reject
√
6.1.12
High current The current of LCD is higher than the standard one. Reject
