A method may include generating display driver signals that vary between only two levels and applying the display driver signals to opposing electrodes of a display segment within a display device. An intrinsic capacitance of the display device filters the display driver signals to generate different analog signal levels at the display segment of the display device. The method varies the pulse density of the display driver signals to select or de-select the display segment based on an average voltage magnitude across the display segment over a time period. The display segment is activated when the average voltage magnitude exceeds a threshold value.

Digital driving circuits, methods and systems for display devices

Disclosed herein are systems, methods, and devices for power and energy metering. Devices may include first processing logic coupled to an isolator and configured to receive a first bit stream from a first modulator via the isolator. The first bit stream may be generated by the first modulator based on a first analog signal. The first processing logic may be further configured to receive a second bit stream from a second modulator via the isolator. The second bit stream may be generated by the second modulator based on a second analog signal. The processing logic may be further configured to generate a third bit stream based on a combination of the first bit stream with the second bit stream. The devices may also include second processing logic configured to generate an output signal based on one or more values of the third bit stream. The output signal may characterize a measurement of electrical power associated with an electrical circuit.

Systems, methods, and devices for energy and power metering

A method may include controlling a display device in at least first mode by varying a correlation between display driver signals applied across display segments within the display device; wherein the display driver signals vary between substantially only two levels, and a display segment is activated when an average voltage magnitude across the segment over a time period exceeds a threshold value.
