Ngokuthuthuka okusheshayo kobuchwepheshe be-LED, imikhiqizo yokubonisa ye-LED ikhombisa ukuthuthuka okuhlukahlukene. Izikrini zanamuhla zokubonisa i-LED zisetshenziswa kabanzi ezimbonini ezahlukahlukene. Kodwa-ke, kwabaqalayo, kusetshenziswa amagama amaningi obuchwepheshe wokubonisa kwe-LED. Angazi, ngakho-ke yimiphi imigomo ejwayelekile yezobuchwepheshe yokuboniswa kwe-LED?
Ukukhanya kwe-LED: Ukukhanya kwediode ekhipha ukukhanya kuvame ukuboniswa yiLuminous Intensity kumayunithi weCandela cd; I-1000ucd (i-micro-candela) = 1 mcd (isiduli candela), i-1000mcd = 1 cd. Ukuqina kokukhanya kwe-LED eyodwa yokusetshenziswa kwasendlini kuvamise ukuthi kube yi-500ucd-50 mcd, ngenkathi ukukhanya kwe-LED eyodwa yokusetshenziswa kwangaphandle kufanele kube yi-100 mcd-1000 mcd noma i-1000 mcd noma ngaphezulu.
Imodyuli ye-pixel ye-LED: Ama-LED ahlelwe nge-matrix noma ingxenye yepeni, futhi enziwa ngamamojula wosayizi ojwayelekile. Isibonisi sasendlini esivame ukusetshenziswa imojula ye-8 * 8 pixel, module 8 word 7-segment module. Imodyuli yephikseli yokubonisa yangaphandle inezincazelo ezifana namaphikseli angama-4 * 4, 8 * 8, 8 * 16. Imodyuli ye-pixel yesikrini sokubonisa sangaphandle nayo ibizwa ngokuthi yimodyuli yenqwaba yenhloko ngoba iphikseli ngayinye yakhiwa izigaxa zamathubhu e-LED amabili noma ngaphezulu.
I-Pixel ne-Pixel Diameter: Iyunithi ngalinye (lechashazi) le-LED elilawulwa ngawodwana ekubonisweni kwe-LED libizwa nge-pixel (noma i-pixel). Ububanzi be-pixel ∮ bubhekisela kububanzi be-pixel ngayinye ngamamilimitha.
Ukulungiswa: Inombolo yemigqa namakholomu wamaphikseli wokubonisa we-LED ibizwa ngokuthi ukulungiswa kwesibonisi se-LED. Ukulungiswa kwenani eliphelele lamaphikseli kusibonisi, okunquma amandla olwazi wesibonisi.
Isikali Esimpunga: Isikali esimpunga sisho ukuthi ukushintsha kwephikseli kuguquka kangakanani. Isikali esimpunga sombala oyinhloko ngokuvamile sinamazinga ayi-8 kuye kwayi-12. Isibonelo, uma ileveli empunga yombala oyinhloko ngamunye ingamazinga angama-256, esikrinini sombala oyinhloko ombaxambili, umbala wokubonisa ungumbala we-256 × 256 = 64K, obizwa nangokuthi isibuko sokubonisa umbala esingu-256.
Imibala eyinhloko emibili: Imibukiso eminingi ye-LED namuhla izikrini zombala eziyinhloko ezimbili, okungukuthi, i-pixel ngayinye ine-LED emibili efayo: eyodwa yokufa okubomvu nenye yokufa okuluhlaza. Iphikseli ibomvu lapho kukhanya okubomvu, okuluhlaza okotshani kuluhlaza lapho kukhanya okuluhlaza okukhanyayo, ne-pixel kuphuzi lapho okufa okubomvu nokuluhlaza kukhanya ngasikhathi sinye. Phakathi kwazo, okubomvu nokuhlaza kubizwa ngemibala eyinhloko.
Umbala ogcwele: umbala obomvu noluhlaza okotshani ophindwe kabili ophindwe kabili oluhlaza okwesibhakabhaka, imibala emithathu eyinhloko yakha umbala ogcwele. Njengoba ubuchwepheshe bokwenza amashubhu anombala ophelele ohlaza okwesibhakabhaka nokufa okuluhlaza okumsulwa manje sekuvuthiwe, imakethe ngokuyisisekelo inombala ogcwele.
I-SMT ne-SMD: I-SMT ubuchwepheshe be-surface mount (bufushaniswa ne-Surface Mounted Technology), okuyimanje ubuchwepheshe obudume kakhulu nenqubo embonini yomhlangano we-elekthronikhi; I-SMD iyithuluzi lokuphakama komhlaba (elifushane ngedivayisi efakwe ku-Surface)
