Abstract
The methods and systems presented herein use well-known logic devices in combination with one or more pulse-width-modulation (PWM) devices in order to create left- and right-justified width-modulated pulses. In some embodiments, justification ability is added without the need to alter an existing PWM device. In some embodiments, the generation of justified pulses is accomplished by a logic circuit in combination with an inherently left- or right-justified PWM device. Some embodiments of the present invention may include, for example, any combination of logical selectors, inverters, and flip-flops. In some embodiments, a justification circuit may receive as input any combination of one or more bits of pixel data, one or more bits of justification selection data, and one or more clock signal. In some embodiments, a justification circuit may output one more signals representing left or right-justified pulses.
