Izimpawu eziyindilinga zinikeza i-engeli yokubuka ebanzi, okwenza kube lula kubasebenzisi ukuthi babone ulwazi lwesikrini ngama-engeli ahlukene kunesikwele esivamile noma izibonisi eziwunxande. Lokhu kwenza izimpawu eziyindilinga zilungele izimo lapho ukubonakala kubaluleke khona, njengezibonisi zezimoto noma okokusebenza kwezimboni. 2. I-engeli yokubuka elungiselelwe Izimpawu eziyindilinga zithuthukisa umuzwa wokubuka futhi zifanele ukusetshenziswa ezindaweni ezihlukahlukene. 3. Ukuhlukahlukana Njengoba izimpawu eziyindilinga zingaklanywa ngobukhulu obuhlukahlukene kanye nokwakheka, zingasetshenziswa kabanzi kumawashi ahlakaniphile, izilandeleli zokufaneleka, izibonisi zezimoto, nezilawuli zezimboni. Ubuchwepheshe bukhona yonke indawo ekuphileni kwethu kwansuku zonke, futhi izibonisi ze-LCD zingenye yazo.
