TheCS ea DCS (DisplayCommandSet) ke sete e tloaelehileng ea litaelo bakeng sa li-module tsa pontšo ka mokhoa oa taelo.
DSI, CSI (DisplaySerialDisplay, CameraSerialInterface)
DSI e hlalosa sebopeho sa serial se lebelo le phahameng lipakeng tsa processor le module ea ponts'o.
CSI e hlalosa sebopeho sa serial se lebelo le phahameng lipakeng tsa processor le module ea khamera.
D-PHY: E fana ka litlhaloso tsa lera la 'mele bakeng sa DSI le CSI
2, sebopeho sa DSI layered
DSI e arotsoe ka mekhahlelo e mene, e tsamaellanang le D-PHY, DSI, DCS, sets'oants'o sa sebopeho sa hierarchical ka tsela e latelang:
PHY e hlalosa sebaka sa phetiso, potoloho ea ho kenya / sephetho, oache le mochini oa matšoao.
Lane Management Layer: Romela le ho bokella phallo ea data tseleng ka 'ngoe.
Low Level Protocol layer: E hlalosa hore na liforeimi le liqeto li entsoe joang, ho lemoha liphoso, joalo-joalo.
Lera la ts'ebeliso: E hlalosa khouto ea boemo bo holimo le phallo ea data.
