Abstract
A touch display having advanced-fringe-field-switching liquid crystal structure, including a pixel cell and a multiplexer circuit, wherein the multiplexer circuit is used to couple the pixel cell with a source driver unit to provide a fringe-field-switching display function during a display period, and couple the pixel cell with a touch detection unit to provide a touch detection function during a touch detection period.
