Abstract: A multi-touch capacitive touch sensor panel can be created using a substrate with column and row traces formed on either side of the substrate. To shield the column (sense) traces from the effects of capacitive coupling from a modulated Vcom layer in an adjacent liquid crystal display (LCD) or any source of capacitive coupling, the row traces can be widened to shield the column traces, and the row traces can be placed closer to the LCD. In particular, the rows can be widened so that there is spacing of about 30 microns between adjacent row traces. In this manner, the row traces can serve the dual functions of driving the touch sensor panel, and also the function of shielding the more sensitive column (sense) traces from the effects of capacitive coupling.

Abstract: A user interface of a controller has multiple touch-sensitive input transducers, e.g., capacitive pads. The pads are dynamically indicated: When any given touch sensitive input device is needed for input at a given step of the programming operation, an associated light source illuminates that input device so it is visible to the user. Those touch-panel input devices not needed for that are left unilluminated, and the microprocessor ignores any input from those input devices. At each step of the operation or programming of the controller, only those input transducers for the inputs that are permitted or relevant to that state are indicated. Correspondingly, only the inputs that are generated by actuating the input transducers for the valid (i.e., permitted or relevant) inputs results in a change in the state of the program in the microprocessor.
