Ubudlelwano phakathi kwebanga lokubuka kanye nesikhala sesibonisi se-LED baziwa ngokuthi iphikseli yokuphakama. Ukuphakama kwe-Pixel kumele isikhala phakathi kwephikseli ngayinye (i-LED) esibonisini futhi kukalwa ngamamilimitha.
Umthetho ojwayelekile ukuthi ukuphakama kwephikseli kufanele kube kuncane kuzibonisi ezihloselwe ukubukwa kusuka kude futhi kube kukhudlwana kuzibonisi ezihloselwe ukubukwa ukusuka kude.
Isibonelo, uma isibonisi se-LED sihloselwe ukuthi sibukwe kude (endlini noma ezinhlelweni ezifana nezimpawu zedijithali), ukuphakama kwephikseli okuncane, okufana no-1.9mm noma ngaphansi, kungase kulunge. Lokhu kuvumela ukuminyana kwephikseli okuphezulu, okuholela esifanekisweni esibukhali nesinemininingwane eyengeziwe uma sibukwa eduze.
Ngakolunye uhlangothi, uma isibonisi se-LED sihloselwe ukubukwa kude kakhulu (imibukiso yangaphandle enefomethi enkulu, amabhodi ezikhangiso), ukuphakama kwephikseli okukhulu kuyakhethwa. Lokhu kunciphisa izindleko zesistimu yesibonisi se-LED kuyilapho kugcinwa ikhwalithi yesithombe eyamukelekayo ebangeni lokubuka elilindelekile. Ezimweni ezinjalo, ukuphakama kwephikseli kusuka ku-6mm kuye ku-20mm noma ngisho nangaphezulu kungasetshenziswa.
Kubalulekile ukuthola ibhalansi phakathi kwebanga lokubuka kanye nokuphakama kwephikseli ukuze uqinisekise umuzwa ophelele wokubonwayo kanye nokusebenza kahle kwezindleko zohlelo oluthile.
Ubudlelwano phakathi kwebanga lokubuka kanye nephimbo lokubonisa le-LED kunqunywa ngokuyinhloko ukuminyana kwe-pixel nokulungiswa.
· Ukuminyana kwePixel: Ukuminyana kwePixel kuzibonisi ze-LED kubhekisela enanini lamaphikseli endaweni ethile, ngokuvamile evezwa ngamaphikseli iyintshi ngayinye (PPI). Ukuphakama kwe-pixel density, amaphikseli aminyene esikrinini futhi kucaca kakhudlwana izithombe nombhalo. Lapho ibanga lokubuka lisondela, yilapho kudingeka ukuminyana kwephikseli ukuze kuqinisekiswe ukucaca kwesibonisi.
· Ukulungiswa: Ukulungiswa kwesibonisi se-LED kubhekisela enanini eliphelele lamaphikseli esibukweni, ngokuvamile avezwa njengobubanzi bephikseli buphindwe ngobude bephikseli (isb. 1920x1080). Ukulungiswa okuphezulu kusho amaphikseli engeziwe esikrinini, angabonisa imininingwane eminingi nezithombe ezicijile. Uma ibanga lokubuka liba kude, isixazululo singanikeza ukucaca okwanele.
Ngakho-ke, ukuminyana kwamaphikseli aphezulu nokulungiswa kunganikeza ikhwalithi yesithombe engcono uma amabanga wokubuka eseduze. Ebangeni elide lokubuka, ukuminyana kwamaphikseli aphansi nezinqumo ngokuvamile zinganikeza imiphumela yesithombe egculisayo.
