A thermal insulation system consisting of air or gas filled channels is described, where the channels are filled at the installation site. The planter system comprises four similarly constructed units with progressively deeper soil depths achieved through the use of plastic inserts and grouped according to a pre-arranged design. The second substrate provided with the first sensing layer and the third substrate provided with the second sensing layer constitute a touch unit for sensing a touch signal, and the second substrate and the first substrate constitute a display unit for displaying. The transmitted signal encounters an object and is received as at least one received signal.
