发明名称 Forming modulated signals that digitally drive display elements
摘要 A controller to programmably provide stored values of drive control data (e.g., a ramp value) to a display device. Using the stored values of drive control data, modulated signals, such as pulse width modulation waveforms may be formed to digitally drive display elements of a display device, as an example. In a display refresh period, a first count indicative of a modulation characteristic may be compared to a stored value that corresponds to the first count. This comparison may determine an update for a second count indicative of a display data characteristic based on the stored value. Because only unique stored values may be stored in a programmable storage device, such as a look-up-table, a relatively smaller number of table entries may be stored and programmed in one embodiment. This may substantially reduce the size of the look-up-table and significantly decrease programming time and effort.
