BA71 and BA72 Components
Screen Module
The screen module represents the main unit of the BA71 / BA72. It compri-
ses of a TFT-LCD colour screen, the TFT-interface and an inverter that ge-
nerates the voltage for backlighting the screen. As an option the screens
are available with Touch Screen and a loudspeaker included. Behind the
cover on the back of the BA71 / BA72 you connect the cable.
Remove the cable co-
ver by pushing it in
the direction of arrow
(see picture) and then
taking it off upwards.
Back of the screen
The TFT LCD flat screen is an SVGA-compatible 10.4 inch screen (12.1
inch with the BA72) which is absolutely flickerfree and free of radiation and
has only a low heat emission. It is designed for a resolution of 800 x 600
pixel. Application programs should be used with this resolution!
However, a resolution of 640 x 480 pixel is possible. In graphics mode this
resolution is used during the start of the BIOS or with MS-DOS etc. It is
also used for instance during installation or when configuration problems
occur (protected mode of Windows). The resolution 640 x 480 pixel is im-
plemented through “stretching” and therefore in graphics mode can not
meet the quality of the resolution 800 x 600 pixel.
