5 TOUCH PANEL CONFIRMATION
5.1 Screen configuration
Displayed items
panel x_before =
*
normalized data before calibration (0-255)
panel y_before =
*
normalized data before calibration (0-255)
panel x_after =
*
normalized data after calibration (0-255)
panel y_after =
*
normalized data after calibration (0-255)
Follow the steps below to convert AD value entered from touch panel to the corrected coordinates.
(Follow

in turn. Execute them during regular operation.)
1
Data expansion of raw coordinates
Coordinates after data expansion = (raw coordinates
−
minimum value )
×
255
÷
(maximum value
−
minimum value)
*
If raw coordinates are 0, the coordinates after data expansion should be 0.
2
Coordinates correction after data expansion
(1) If the coordinates are under 224 after data expansion;
Coordinates after correction = coordinates after data expansion
+
correction value
×
(1
−
(coordinates after data
expansion
−
224)
÷
31)
*
31: Because there are 31 points of coordinates position from the value 225 to 255.
*
The effect of correction value declines as the value is going to 255.
(2) If the coordinates are less than or equal to 32 after data expansion;
Coordinates after correction = coordinates after data expansion
+
(correction value
×
coordinates after data
expansion
÷
32)
*
32 : Because there are 32 points of coordinates position from the value 0 to 32 (coordinates 0 is not included).
*
The effect of correction value declines as the value is going to 0.
(3) If the coordinates are 33
∼
224 after data expansion;
Coordinates after correction = coordinates after data expansion

64)
*
64 : Because there are 64 points of coordinates position in each area.
*
Add the correction value at the left corner first. Then, the effect of correction value is increasing as going to right.
5.3 Processing detail
5.2 Operation specification
Check the coordinates before and after correction by touching the touch panel.
Press [ ENT ] key of main unit or remote control unit to return to TOP MENU.
Check displayed coordinates before and after correction when pressing touch panel and perform operation check.
