3. Test Touch-panel
Explanation on touch panel misalignment verification test.
1) The test is intended to verify if the touched point on the touch panel is correctly recognized or not.
[+] cursor will be displayed at 16 locations on the screen.
The cursor will be displayed in “white color“ only one at a time.
Each time the cursor is touched correctly, the next point will be displayed.
On the other hand, if it is recognized that the point touched was
±
4 dots vertically and
±
5 dots horizontally away
from the center of the displayed [+] cursor, the erroneously recognized coordinate [+] will be drawn
in “red color“.
2) When touching the [+] cursor, touch the center of the + mark correctly.
3) If [BACK] is touched, the test will be finished, and the screen will return to the menu screen of the touch panel
test mode.
If this test turns out to be NG, it will be necessary to redo “1. Setup touch-panel effective range“ and “2. Setup
calibration“. Repeat the above steps once again.
