Uma izibani zangemuva ze-LED ezikhanya onqenqemeni zisetshenziswa kuma-LCDs aphakathi nendawo amakhulu, isisindo nezindleko zepuleti lomhlahlandlela wokukhanya zizokhula ngokukhula kosayizi, futhi ukukhanya nokufana kokukhishwa kokukhanya akulungile.Iphaneli yokukhanya ayikwazi ukubona ukulawula okuguquguqukayo kwesifunda kwe-LCD TV, kodwa ingabona kuphela ukufiphala kwe-dimensional eyodwa, kuyilapho ukukhanya okungemuva kwe-LED okukhanyayo kusebenza kangcono futhi kungabona ukulawula okuguquguqukayo kwesifunda kwe-LCD TV.Inqubo ye-backlight eqondile ilula futhi ayidingi ipuleti lomhlahlandlela okhanyayo.Umthombo wokukhanya (i-LED chip array) kanye ne-PCB abekwe ngaphansi kwesibani sangemuva.Ngemuva kokuthi ukukhanya kukhishwe ku-LED, kudlula kusibonisi esingezansi, bese kudlula ku-diffuser ngaphezulu ukuze kwandiswe ukukhanya.Ifilimu ikhishwa ngokulinganayo.Ubukhulu be-backlight ikakhulukazi bunqunywa ukuphakama kwe-cavity phakathi kwefilimu ekhanyayo kanye ne-diffuser.Ngokombono, esimisweni sokuhlangabezana nezidingo zokufaka nokukhanya okukhanyayo, uma kukhulu ukuphakama kwesikhala, kuba ngcono ukufana kokukhanya okukhishwa ku-diffuser.
