More Information
Summary:Light-emitting diode (LED) packages and, more particularly, LED packages with transformation and shifting of pulse width modulation (PWM) signals and related methods are disclosed. Discrete LED packages are arranged for cascade communication. Each LED package includes one or more LED chips, and each LED package is separately capable of receiving communication from a data stream, controlling operation of the one or more LED chips, and performing transformation and shifting of received PWM signals. Transformation may include compression and/or decompression of received PWM signals by each LED package to provide increased accessible dynamic range. After transformation, LED packages are capable of shifting transformed values to compensate for turn-on delay of LED chips, thereby reducing light drop-off problems at low intensity levels.
