Abstract
A method of scanning video information to a pixel array comprises, during a first active row interval, setting a column signal line to an initial voltage, asserting a first row signal line of the pixel array, setting the column line to a desired voltage, and de-asserting the first row signal line when the column signal line is at the desired voltage. The method further comprises, during a second active row interval occurring after an amount of time, setting the column signal line to the initial voltage, asserting the first row signal line of the pixel array, and de-asserting the first row signal line while the column signal line is at the initial voltage. The method further includes, during the second active row interval, asserting a second row signal line, and maintaining the assertion of the second row line for a period of time after de-asserting the first row signal line.
