Claim:
1. Touch-screen control panel interface, comprising a generally flat panel formed of a plate of substantially rigid dielectric material having a front face and a back face, and which has a transparent window portion formed therein; a principal circuit board having a front side and a reverse side, the reverse side being a component side on which circuit elements are mounted, and the front side being flat and without components thereon, the principal circuit board including at least one numeric or alphanumeric display module mounted on the reverse side of the principal circuit board, and the at least one numeric or alphanumeric display module having a visible display on a front face thereof; the principal circuit board having a window cutout at the position where the at least one numeric or alphanumeric display is mounted, the at least one display module being oriented with its front face towards the principal circuit board such that its visible display is situated within said window cutout at the front side of the principal circuit board; a plurality of indicator LEDs mounted on the reverse side of the circuit board at predetermined LED locations thereon; said printed circuit board having apertures formed at said predetermined LED locations such that when energized said indicator LEDs emit light through the respective apertures to be visible at the front side of the principal circuit board; a plurality of metallized capacitive electrode pads formed at predetermined respective locations on the flat front side of the principal circuit board; a microprocessor mounted on the reverse side of said principal circuit board and having a plurality of input electrodes and output electrodes; an array of conductors on said principal circuit board connecting at least some of the input electrodes and output electrodes of the microprocessor to said at least one numeric or alphanumeric display module, to said indicator LEDs, and to said plurality of metallized capacitive electrode pads on the front side thereof respectively; a multi-conductor cable connected with said array of conductors, and extending from said principal circuit board and adapted to connect to a control component associated with said interface; and an adhesive member sandwiched between said circuit board and said flat panel such that the flat front side of the principal circuit board substantially abuts the back face of said flat panel and is affixed thereto.
