14. Touch Screen (Option)
The DLoG X series is optionally available with a resistive touch screen.
The resistive touch screens from DLoG have a sandwich construction. The front control
panel is made of polyester and is separated from the back through very small spacer
dots. The rear of the front and the face of the back are covered which a conductive layer.
Voltage is applied at the corners of the back. By creating the contact between the surface
of the front and the conductive layer the electric circuit is closed, and the contact point
can be calculated from the voltage differences.
14.1. Mouse and keyboard compatibility
Touch screens on the DLoG X-series can be operated with or without a keyboard and
are also compatible with a mouse.
14.2. Functional description
A touch screen controller is integrated into the mainboard to analyze the resistance
changes caused by touch. The touch screen controller provides the resulting data to the
operating system’s touch screen software driver.
The analog touch panel controller used for analysis provides a resolution of 1024 x 1024
pixels (10-bit horizontal and vertical).
14.3. Operation
Inappropriate operation of the screen, for example, by using sharp objects such as
screwdrivers, will irreparably damage the touch screen.
Please observe chapter 8.1 Touch screen operation .
14.4. Drivers
Touch screen drivers are a core component of DLoG Images for Windows CE or
Embedded Linux.
