2. TOUCH SCREEN CAPACITIVE SENSOR

INSTALLATION

REMOVABLE VERSION

IMPORTANT

The sensor must be handled carefully to avoid creasing or tearing. Rippling may occur

during delivery, but this will disappear during the lamination process;

Always lay the interactive sensor on a soft scratch free surface where possible;

A soft cloth should be used if the sensor requires cleaning, clean from the centre of the

sensor out to the edges of the interactive sensor;

If for any reason, after the lamination process, water enters the electronics board of

the DISPLAX™ SKIN MULTITOUCH please allow sufficient time to dry before using. If the

controller is not dry when you connect the sensor will not function correctly and may

be permanently damaged;

If water bubbles remain under the sensor do not be tempted to pierce to the sensor to

remove, these should evaporate over time, in some situations it can take more than a

week depending on environmental conditions;

It is important to ensure no particles of dust remain under the removable adhesive for

the best finish. When using the removable version it is possible to carefully lift the skin

to remove nay particles and carefully reapply using water and the squeegee.

INSTALLATION TOOLS

The installation of the removable version of the sensor requires the use of the following tools:

Distilled water

Liquid sprayer/atomizer

Soft cleaning cloth

Squeegee

Sticky tape (masking tape)

Velcro or double-sided tape

MKT.154.0

BEFORE YOU START, PLEASE NOTE:

The sensor has a front and a back: when installed, from the side towards the installer, the DISPLAX™ logo should be readable as shown in the picture below.

After the final installation, the sensor should look like this with the components on the controller facing away from the substrate.

MKT.154.0

INSTALLATION

1. Decide on the correct position of the touch screen before starting the lamination

process, and place sticky tape to mark the touch screen boundaries.

2. Dirt and other contaminants allow pockets of air that undermine the necessary seal for

a good installation. Thoroughly clean the substrate making sure it is free of dust, oils or

grease:

a. use the distilled water and squeegee to clean the substrate just before

lamination;

b. apply a fine mist of distilled water to the substrate using a water

sprayer/atomizer.

3. Carefully remove the paper backing material from the removable adhesive.

MKT.154.0

4. Apply the removable adhesive to the substrate, and apply a fine mist of distilled water.

5. Use the squeegee to laminate the adhesive to the substrate, ensuring no particles or

dirt is underneath.

MKT.154.0

8

6. Apply a fine mist of distilled water to the front of the removable adhesive. Lay the

sensor on the adhesive in the correct position. Do this from one side to the other

allowing the sensor to “wet” itself in place as it lays onto the substrate.

Then apply a fine mist of distilled water to the surface of the sensor and squeegee in

place. Remove excess water using a squeegee working from the centre to the edges of

the sensor. Apply an even pressure.

If dirt or particles can be seen under the sensor, then the sensor can be carefully lifted

and the dirt removed. The sensor should be squeegeed back in position using a fine

mist of water.

MKT.154.0

7. Once the sensor is in place, carefully dry the surface and the area around it and leave

to dry for some time.

8. The electronics should be securely fixed to the substrate once the installation has

dried.

3. CONTROLLER CONNECTION

1. Once the interactive sensor installation has been completed and the touch sensor is

sufficiently dry, the controller board can now be connected to the sensor. Please note

that if the board is connected to the sensor too soon after the installation process, the

extra weight of the board may cause the sensor to move away from its original

position.

NOTE: We suggest using Velcro or double-sided tape to hold the controller in position

on the substrate.

2. Carefully lift the clamping clip (grey bar) as shown on the following picture, taking care

not to over extend the clamping clip.

3. Make sure you connect the sensor cables at the right side, which is visible by

comparing the DISPLAX™ logo position at the ribbon cable and the DISPLAX™ logo

position on the controller board (see the following picture).

Align the position of the controller connectors with the orange ribbon cables. Both the

board’s components and the metalized bars of the ribbon cables should be facing up,

and both logos should match.

4. Gently insert the ribbon cables into position.

5. Once each ribbon cable is inside the connector, lock it, by gently pressing down the

clamping clip.

6. Plug the power adapter cable to the power connector on the board, which is located at

the top-left side of the controller. Our tests demonstrate it might not be needed. We

would like you to test this also. To ensure we added this power supply for now.

7. Plug the USB cable to the USB connector on the board, which is located at the bottom-

left side of the controller.

8. Two ground cables (female plug) are connected to the controller board.

MKT.154.0

13

9. Plug either of the ground cables to the sensor’s ground cable (male plug).

10. If you wish to install the sensor on the top of a display, it is advised to connect the

second ground cable of the controller to the ground cable of the display. This cable

must be properly attached to the display’s ground point (check your display’s user

manual for details).

11. After connecting the power, USB and ground cables, connect the other side of the USB

cable to the computer and plug in the power adapter.

4. DRIVER AND CONTROL PANEL INSTALLATION

The Driver and Control Panel is compatible with both the 32 and 64-bit versions of Microsoft

Windows 7 operating system, and the installer is provided in two distinct files (‘Setup_x86.exe’

for the 32-bit version, and ‘Setup_x64.exe’ for the 64-bit version).

Procedure

If you wish to install the Driver and Control Panel in a 64-bit system, please reboot your

computer. During startup (before the Windows logo appears), repeatedly press the F8

key to enter the Advanced Boot Options menu, and choose the Disable Driver

Settings tab

In case the controller is unconnected, the Settings tab displays the following image.

The display below the tabs identifies the sensors status and plots the sensitive region. A white

mark identifies a touched point and the black background identifies the untouched area.

MKT.154.0

31

The red marks identify the sensitive area limits (touches outside the sensitive area are not

processed).

You can define the sensitive area dimensions, which is displayed as a black region within the red

marks, by moving each horizontal line top/down and each vertical line left/right, as shown on

the following picture.

The sensitive area may occupy any region of the touch sensor, and can take any aspect ratio.

MKT.154.0

32

The following picture displays two touches within the sensitive area.

The following picture displays six drags within the sensitive area.

MKT.154.0

The Sensitivity slider allows the user to increase or decrease the sensors sensitivity (default

value at centre). If you wish to adjust the sensors sensibility to a thinner glass, then decrease the

sensitivity (move slider to low); if you wish to adjust the sensors sensitivity to a thicker glass,

then increase the sensitivity (move slider to high). The sensitivity must be adjusted without

losing continuous touch detection.

The Tracking slider allows the user to choose between a very smooth and a fast touch tracking.

If you wish a very smooth touch tracking, move the slider in the smoother direction, otherwise,

move the slider in the faster direction.

The Noise Reduction slider allows the user to compensate for any electromagnetic

interferences, noise and fake touches, by changing the noise reduction amplitude. Move the

slider between none and maximum until the undesired effects are fully eliminated.

The Geometric calibration section allows the user to launch the geometric calibration tool

(Calibrate button), and to reset the geometric calibration to the default values (Reset button).

BEST SENSITIVE ADJUSTMENTS

To adjust the sensing and get the best performance it is needed to adjust the sensitivity bar so

that the touch screen is just sensitive enough to a smooth touch but also is not available for

non-intentional touches of approximate fingers of even available to send touches coming from

electrical interferences. So the way you can see which is the best setting is to adjust the

sensitivity bar and try the best level. Usually in our experiments we need just the bar around the

middle, sometimes higher, sometimes lower, but we never needed in the maximum. So see

some examples of good and bad setting.

GOOD EXAMPLE: Why? The white touch

balls, representing two fingers, area round /

circular, meaning the touch is well defined

and just receiving touches when I

intentionally touch. So you should try to get

the best round ball with the minimum white

area around it. As more white area around

the ball you get the more non-intentional

touches you´ll get.

The right setting is a trade-off between glass

thickness, good touch tracking during a touch

and also during a drag movement. So this

needs to be adjusted after installation.

BAD EXAMPLE: Why? The white touch balls,

representing two fingers, are not round and

so the touch will be activated with non-

intentional touches. Means also the

Sensitivity bar is very high and any

interference will activate the touch. It´s

needed to reduce the Sensitivity bar and

maybe activate and Auto Setup to readjust

the touch. If this was not enough please use

the Noise Reduction slider and move it to the

middle.
