I wanted to attach an LCD touch screen to the top of the kit. The lid has a diagonal of about nine inches (22cm) so a 6, 7 or 8 inch screen will do.
The options are:
A portable LCD screen unit with a VGA interface such as:
An LVDS LCD display such as:

A TFT Flat Panel Display such as:
The first type is simplest as it requires no internal changes to the box. These are priced at about $A400 upwards.

Smartphones typically have an LCD graphical screen with touch input. Touch is used to take user input via windows controls such as menus and command buttons. A SIP (Software Input Panel) may also be used am on-screen keyboard. Alternatively, some phones use a small physical keyboard. Some use both.

I had to subscribe to a video converter because the phone’3G video format needed changing.
My main implementation issue was that I only got the LVDS LCD panel at the last moment and discovered that I hadn’t ordered the touch screen version; and it required 12V that wasn’t available in the kit. I wrote about these in the report and will blog all of this. I got the touch panel tod ...
