Prevention of EM noise problem
Some transformers or coils in the po
power
er unit
nit generates EM noise
noise.
To prevent this
•
•
•
Use transformers or coils that won’t allow magnetic flux leakage.
Place them underneath the shield or in a distance as much as possible from the
sensor board.
Position them so that EM noise flux did not across the sensor board.

Inverter is one of the strongest EM source.
Shielding the inverter with shield plate*1, would improve

Reduction of metal influence
Some metal structure reduces digitizer signal which causes coordinate error.
To prevent this
•
•
Do not use metal for upper case.
Contact Wacom to make Error calibrated firmware data.


EM noise environment
EM noise which mimic pen signal can cause digitizer malfunction.
• Wacom will search the EM noise and measure the level
level.
•
28 • 30.10.2007 • Wacom Confidential
9-3. System Calibration

Coordinate stability

EM noise can cause vibration of coordinate detected by digitizer (jitter).
 Wacom quantifies the level of jitter by take 100 coordinate data at each
spot and calculating standard deviation and max deviation from mean
location.


Metal parts or EM noise will disturb digitizer signal and can cause the
deterioration of digitizer accuracy.
Digitizer signal can be compensated by calibration up to certain level.
Wacom measures the accuracy before and after calibration.

Note:


Calibration is required for each design. Any material or design
changes will need another calibration.
When several LCDs are applied for one model
model, FW needs to be
created for each LCD.
