We would like to share with you a few experiences appeared while integrating and using a touch screen.
Not a lot, because following the User Manual you must be able to work with our Touch Screens without any problem.
For anything else we can do for you, don’t hesitate to let us know.

PRODUCT: ZYBRID XY 42” & 47” TRANSFLECTIVE TT MONITOR ZYBRID X TOUCH SCREEN AND 4+4MM SACRIFICIAL GLASS
PROBLEM: AUTO CLICKS AND CURSOR IS NOT STABLE, UPON FLICKERING
SOLUTION:
1. Check the sensibility in the Test Sensor menu (Hardware + Firmware Options + Test Sensor)
2. If you don’t touch the screen, values should be between 0 and 4 maximum, if over 4 we have an EMC problem, so electromagnetic interferences.
3. Please separate the touch screen from the rear metal frame
4. Please ground the Touch Controller Board
5. Please increase the Threshold in order to reduce the sensibility, and increase the stability.
If you don’t use a front sacrificial glass you don’t need to have a low value of Threshold (Hardware – Firmware Options – Threshold -by default value is 22, if you don’t use sacrificial glass check maybe with 25)
PLEASE BE NOTED THAT WHILE USING A LARGE SCREEN MONITOR & TOUCH SCREEN PANEL, THERE MUST BE AT LEAST A MINIMUM GAP OF 9MM BETWEEN THE TOUCH SCREEN AND THE FIRST METAL, AND MAKE SURE YOU HAVE ENOUGH GROUNDS, NOT ONLY THE CONTROLLERS BUT ALSO THE METAL CHASSIS AND YOUR TOTEM OR KIOSK.

PRODUCT: TOUCH SCREEN WITH 4+4MM FRONT SACRIFICIAL GLASS
PROBLEM: DIFFICULTIES TO DETECT, SO TO INTERACT WHILE TOUCH
SOLUTION:
1. If we use a sacrificial glass of 4+4MM (8,5MM considering lamination process) + the own 3MM that the touch screen has, we are trying to work with a front sacrificial glass of around 11,5MM. That’s not an issue, but we must care on some parameters.
2. Go to Test Sensor (Hardware + Firmware Options + Test Sensor)
3. The values without interacting (touching) the touch screen must be between 0 and 4, if over we have a EMC (electro magnetic interference)
4. Please separate the touch screen from the rear metal frame
5. Please ground the Touch Controller Board
6. In this particular case while touching the screen values was 19-20
7. Come back and adjust the Threshold In this particular case to 16-17 (Hardware + Firmware Options).
8. Adjust Thickness to “thick” (Hardware + Firmware Options)
9. Another possibility, when we use a very thick sacrificial glass should be to use the touch screen by the film side, instead by the front 3MM glass, that’s means to integrate the touch screen with the 3MM on the back side – panel - and the wires & film on the front side.
With this “tip” you will improve definitely the sensitivity.

PRODUCT: 15” MONI SMART WITH ZYBRID XY AND SACRIFICIAL GLASS
PROBLEM 1: DIFFICULTES TO NEITHERMOVE THE CURSOR TO THE EDGE BORDERS NOR RECEIVE A TOUCH, BUT WORKS PERFECT IN THE CENTER OF THE SCREEN.
SOLUTION:
- Zytronic always suggest that the first “interactive virtual button” must be allocated ideally at a minimum of 10MM distance “inside” the metal edge border. That’s because is usual that touch screens are less sensible at the borders.
- Use the use the Edge Acceleration function within the UPDD driver. This function allows the cursor to be accelerated into the extreme edges of the display. The starting point parameters are shown below. Navigate to the following: Start + Program Files + UPDD + Settings + Properties Page on the UPDD console + Advanced button. This will pop up the page below. Now enter the values as shown below and press the OK button. This should improve edge performance.
Notes:
a- “Width” is the number of pixels from the edge border where we want to increase the sensibility.
b- “Gain” is the sensibility value we will increase.
c- The new setting values you can see are those recommended by Zytronic to improve the sensibility at the edges borders, as first test. From the feedback perception you will get, you can change the values until your desiderate optimal feedback.
d- If you increase the sensibility value, so you reduce the Threshold, then the touch screen works much better at the edge borders, but it becomes too sensible in the middles, so before to touch the screen we receive a touch feedback, and cursor shows instability.
