The mechanical architecture of the platform enables support of various types and sizes of user interface.
The CE-500’s user interface is an entirely independent module, which is connected to the device’s core
layer.
The platform currently supports two types of the user interface:
7” display based - CE-507 device model
4.3” display based - CE-504 device model
A type of the user interface type automatically detected during system startup.
The required user interface type (device model) must be specified while ordering the device.
The user interface model can be ordered separately as well (for field upgrade by a technician). For field
installation of the CE-500 user interface modules, see page

The CE-504 device model provides a 4.3” Touch Color display with WQVGA (480 X 272 pixels)
resolution.
The CE-507 device model provides a 7” Touch Color display with WVGA (800 X 480 pixels) resolution.
Both models are based on the transflective TFT LCD technology, provide the high contrast display,
support 16M colors, and provide a multi-level white LED backlight with a typical luminous intensity of
400 cd/m2.
The platform enables developers to change the display mode to set up the landscape or portrait
orientation programmatically. In addition, developers can enable the automatic change of the display
mode based on a cradle state signal. Developers can use this ability to manage how applications are
displayed in vehicle and out-of-cab operations.
