==Direct addressing==

A '''direct-driven''', or '''directly addressed'''{{Citation needed|date=March 2025}} display runs individual control signals to each pixel. This allows the state, whether on/off or grayscale, to be set and maintained on each pixel. For a screen size of ''m''×''n'' pixels, this scheme would require ''m''×''n'' control signals in grayscale. This is generally considered to be inefficient, and is technically impossible for modern displays -- for example, 1920 x 1080 pixels and an RGB system (3 times as many control signals needed) results in ~6 million control lines.<ref name=":0">{{Citation |last=Blankenbach |first=Karlheinz |title=Direct Drive, Multiplex and Passive Matrix |date=2012 |work=Handbook of Visual Display Technology |pages=417–437 |editor-last=Chen |editor-first=Janglin |url=https://link.springer.com/referenceworkentry/10.1007/978-3-540-79567-4_33 |access-date=2025-03-06 |place=Berlin, Heidelberg |publisher=Springer |language=en |doi=10.1007/978-3-540-79567-4_33 |isbn=978-3-540-79567-4 |last2=Hudak |first2=Andreas |last3=Jentsch |first3=Michael |editor2-last=Cranton |editor2-first=Wayne |editor3-last=Fihn |editor3-first=Mark|url-access=subscription }}</ref>
