The Flat Panel Display BA72A-2
General
The TFT LCD flat panel display is an SVGA-compatible 12-inch flat panel
display which is absolutely flickerfree and low radiation. It is designed for a
resolution of 800 x 600 pixel. Application programs should be used with this
resolution!
The screen module represents the main unit of the BA72A-2. It comprises of
a TFT-LCD colour screen, the TFT-interface and an inverter that generates
the voltage for backlighting the screen. As an option the screens are
available with Touch Screen including a beeper.

Capacitive Touch Screen (Option)
General
The TFT Touch Screen works according to the principle of a change in
analog capacitance. It has a glass screen with a transparent, thin-film
overlay on the surface. This is fully sealed and protected by a further layer
of clear glass. Electrodes on the edges of the screen provide an uniform
low-voltage field. As soon as you touch the screen with your finger the
contact point is “recognized” by the change in capacitance.
Because this takes place very quickly the Touch Screen is optimally
equipped for a number of different requirements and applications.
The programming interface of the screen is identical to the mouse interface.
When you connect your new BA72A-2 to your BEETLE for the first time you
have to calibrate the Touch Screen. Details depend on the operating system
that you are using.
How to Operate
The Touch Screen responds to the slightest contact, therefore you do not
have to apply much pressure when working with the screen. This does not
only safe time, but is also kind to your joints!
Touching the touch glass has the same effect as clicking the left mouse
button. You only need to apply a little pressure with the fingertip. In this
capacitive process only fingertip contact is recognized. The screen does not
react in any way if touched, for example, with a pencil or a glove.

You can adjust the brightness and the loudness with the thumb wheels
located down to the right of the front of the screen.
Cleaning Instructions
Always turn off the system before cleaning.
The glass surface of your Touch Screen should be cleaned with a mild,
abrasive free, commercially available glass cleaning product. All pH neutral
materials (pH 6 to 8) are good for cleaning. Cleaners with pH values 9 to 10
are not recommended. Cleaning with water and isopropyl alcohol is possible
as well. Do not use solvents containing acetic acid. Use a soft, fine-meshed
cloth to clean the surface. Dampen the cloth slightly and then clean the
screen.
A wrong maintenance may cause damages to the screen, which are not
covered by guarantee or warranty.

Resistive Touch Screen (Option)
General
The resistive TFT Touch Screen is constructed of a hard-coated polyester
topsheet that is overlaid on a conductively-coated glass layer. Voltage is
applied to the topsheet. As the user touches the screen, the topsheet
compresses into contact with the glass layer, and current flows to the four
corners in proportion to the distance from the edge. The controller then
calculates the position of the finger or stylus, based on the current flow.
Because the controller derives both the “X” and “Y” touch coordinates from
the stable glass layer, the accuracy and operation of the touch screen is
unaffected by damage to the topsheet caused by extended use or neglect.
Construction of the resistive Touch Screen
When you connect your new BA72A-2 to your BEETLE for the first time you
have to calibrate the Touch Screen. Details depend on the operating system
that you are using.
How to Operate
Touching the touch screen has the same effect as clicking the left mouse
button. You only need to apply a little pressure with the fingertip. In this
resistive process not only fingertip contact is recognized. The screen does
react in any way if touched, for example, with a stylus. The recommended
material for a stylus is polyacetal. The stylus should have a minimum

spherical radius of 0.8 mm and contain no sharp edges or burrs that may
cause damage to the topsheet.
Cleaning Instructions
Always turn off the system before cleaning.
The surface of your Touch Screen should be cleaned with a water-based
solvent or a non-abrasive cleaner.
Do not use solvents containing acetic acid or methylene chloride. Use a
soft, fine-meshed cloth to clean the surface. Dampen the cloth slightly and
then clean the screen.
RESISTIVE TOUCH SCREEN (OPTION)

Infrared Touch Screen (Option)
General
The infrared (IR) technology is based on the interruption of a grid of IR light
beams before the surface of a screen. The touch frame contains a row of
infrared light emitting diodes (LEDs) and photo transistors, each mounted
on two opposite sides to create a grid of invisible infrared light. The screen
is made of frames. The electronic is concealed behind an infrared-
transparent bezel, which allows the infrared beams to pass through.

IR light beams are produced and transmitted over the surface of the screen,
the photo sensors accept the beams. When an object (min. 7mm Ø), such
as a finger, enters the grid, it obstructs the beams. One or more photo

sensors detect the absence of light and transmit a signal, that identifies the
x and y coordinates.
Breaking through the grid has the same effect as clicking the left mouse
button.
To avoid malfunctions: Do not fix labels or stickers on the frame and do not
put pencils or the like on the inner frame.
Cleaning Instructions
Always turn off the system before cleaning.
The glass surface of your Touch Screen should be cleaned with a mild,
abrasive free, commercially available glass cleaning product. All pH neutral
materials (pH 6 to 8) are good for cleaning. Cleaners with pH values 9 to 10
are not recommended. Cleaning with water and isopropyl alcohol is possible
as well. Do not use solvents containing acetic acid. Use a soft, fine-meshed
