MOBILE ELECTRONIC DEVICE WITH CAPACITANCE SENSOR WITH RESTRICTED VISIBILITY ISOLATION AREAS, AND APPROPRIATE METHOD Russian patent published in 2011 - IPC G09G3/36 G02F1/00 G06F3/01 G06F3/48 

FIELD: information technologies.

SUBSTANCE: mobile electronic device includes a capacitance sensor, having an electrode layer with non-etched sections and etched sections, and having isolation areas formed on etched areas, and a segmented optical gate arranged on the side of the capacitance sensor, besides, the optical gate includes a liquid crystal layer inserted between an upper absorbing polariser and a lower absorbing polariser, and includes an element of reflective property increase, arranged between the liquid crystal layer and the lower absorbing layer. The reflective property of the element of reflective property increase is selected to reduce the ratio of the reflective property on non-etched areas to the reflective property on etched areas to make the user interface appearance substantially uniform in off condition.

EFFECT: providing the user with various configurations of keyboard buttons required to the user depending on the used mode of the device operation.
