COLOR ELECTRO-OPTIC DISPLAY DEVICE WITH DAC DRIVER CIRCUIT WITH PIXEL RESETTING MEANS

摘要

In a digital-to-analog (DAC) driver circuit for a color electro-optic display device employing a global ramp generator, color artifacts caused by the residual state of the electro-optic material of the pixels from previously addressed data signals are substantially reduced or eliminated by providing a resetting pulse from the ramp generator to selected pixels prior to addressing with the next set of data signals.
