Ngenxa ye-passive drive: (1) ayivumeli ukukhiqizwa kwendawo enkulu, ayikwazi ukuhlangabezana nezidingo ze-large-screen drive; (2) Izici ze-column scanning drive, kulula ukukhiqiza ukukhanya kwe-pixel yekholomu okungalingani, okuholela ekulinganiselweni kwesithombe sokubonisa kanye nesisombululo; (3) Iphimbo le-pixel liyancipha kancane kancane, imodi ye-passive drive yebhodi le-PCB lendabuko ayikwazi ukuhlangabezana nesidingo se-drive, futhi inezinkinga eziningi ekusetshenzisweni kwe-Micro LED, ngakho-ke, uhlelo lokuklama i-active drive olumelwe yi-CMOS ne-TFT luzoba umngane omuhle wokuthuthukiswa kobuchwepheshe be-Micro LED. Isibonelo, kubuchwepheshe bokushayela be-CMOS, ukuze kudlule ubuchwepheshe bokudlulisa izibopho, imboni yamanje igxile ekuhloleni ubuchwepheshe bokubopha be-Micro LED kanye ne-CMOS driver circuit.
