A line or block does not light up in address electrode direction.
(1 line, block open).
Manufacturing: Panel electrode single line/ foreign
material./electrostatic/ TCP defect.
Another color simultaneously appears because adjacent data
recognizes the single pattern signal.
Manufacturing: Panel electrode short/ Foreign material conductive
foreign object inside TCP.
A defect other than address open and short Data
printout signal error occurring at certain Gradation or pattern.
One or more line do not light up in Sustain direction.
- Manufacturing:. Panel bus electrode single line FPC pressure defect.
- Parts: FPC/board/connection disconnection
- Operation: assembly error.
Sustain (horizontal stripe) Short.
Combined or adjacent
lines are short in sustain direction. The line appears brighter than other at
Ramp gradation pattern or low gradation pattern.
Dielectric material layer damage.
Burn caused by the damage of address bus dielectric layer
appears in the panel discharge/non discharge area. sustain also open/short
occurs by the damage of address sustain printout. [Add Block and Line Open]
- Manufacturing: Panel electrode short/Foreign material.
- Parts: Board/ connector/pin error
- Operation: connector / assembling error.
Layer uneven /
abnormal voltage / foreign material repair failed.
