1. Siyini isikrini sokubonisa esiholwa?
Isikrini sokubonisa esiholwa yiphaneli esiyisicaba esakhiwa isikhala esithile nokucaciswa kwamaphuzu akhanyayo. Indawo ngayinye yokukhanya iqukethe isibani esisodwa se-LED. Ngokusebenzisa ama-diode akhanyisekayo njengezinto ezibonakalayo njengezinto zokubonisa, kungakhombisa umbhalo, ihluzo, izithombe, izithombe, izitayela zemakethe, ividiyo nezinye izinhlobo ezahlukahlukene zolwazi. Ukuboniswa kwe-LED kuhlukaniswe ngezigaba ezinkomeni zesifo sohlangothi kanye nemibukiso yezinhlamvu, njengamashubhu wedijithali, amashubhu we-mbort matrix, amashubhu okubonisa amazinga, njll.
2. Kusebenza kanjani isikrini esiholwa nge-LED?
Umgomo osebenzayo wesikrini sokubonisa esiholayo ubandakanya ukusebenzisa izici zokufakelwa okukhanyayo okukhanyayo. Ngokulawula amadivaysi aholwa ukuze wakhe uhlu, isikrini sokubonisa siyadalwa. I-LED ngayinye imele i-pixel, futhi ama-LED ahlelwe abe amakholomu ahlukene nemigqa, akha isakhiwo esinjengegridi. Lapho okuqukethwe okuthile kudinga ukuboniswa, ukulawula ukugqama nombala we-LED ngayinye kungadala isithombe noma umbhalo oyifunayo.
