240320DL various questions

Hi,

I have some questions about the Displaytech 240320DL series:

My dealer has two reference numbers:

240320DL-FC-BC-3TS
240320DL-CC-BC-3

Are both of them enabled with the touch screen option (apparently the 240320DL datasheet says so)?

I´m interested in the blue backlighted display with the touch screen panel option.

Also, is there a way to dim the backlight intensity - by modifying current / voltage to the A and K pins which supply power to the backlight?

(Sorry I created the post in FAQ, I don´t know how to move it to the proper section)

Thanks
