Please note that all connections are not to exceed their expressed
maximum voltage or current. Maximum signal input values are
indicated in this manual and the corresponding display data sheets. As
damage from improper connections varies according to use and
application, it is the user's responsibility to take appropriate safety
measures to ensure that the module connections are protected from
overloading through connected peripherals.
2.1 Carrier Board Connectivity (X5, X3)
The new concept of using display adapters such as the LCD-014-x and
LCD-017-x allows to attach a large number of different displays
varying in resolution, signal level, type of the backlight, pinout, etc. to
the baseboard using always the same connectors. The new PHYTEC
Display-Interface (PDI) has been designed in order not to limit the
range of displays connectable. It consists of two universal connectors
which provide the connectivity for the display adapter:
The display data connector combines all needed low-current interface
signals.
The display power connector provides all voltages needed to supply
the display and the LED backlight.
They also allow easy adaption to customer displays.
2.1.1 Display Data Connector (X5)
The display data connector at X5 (40 pin FCC connector 0,5mm pitch)
combines various interface signals like LVDS, USB, I
2
C, etc. required
to hook up a display, or a front panel, as well as the low-current
supply voltage for the logic on the adapter board.
