Umboniso we-LED sisixhobo esisebenzisa ii-diode zokukhanya (ii-LED) njengezinto ezikhupha ukukhanya ukubonisa imizobo, iividiyo, ii-animations kunye nolunye ulwazi ngezikrini ze-elektroniki. Umboniso we-LED unenzuzo yokukhanya okuphezulu, ukusetyenziswa kwamandla aphantsi, ubomi obude, i-angle yokubukela ngokubanzi, njl., kwaye isetyenziswa ngokubanzi kwiintengiso zangaphakathi nangaphandle, ukuthutha, ezemidlalo, ukuzonwabisa kwenkcubeko kunye nezinye iindawo. Ukuze uqinisekise isiphumo sokubonisa kunye nokusebenza kokugcina amandla kwesikrini se-LED, kuyimfuneko ukubala indawo yesikrini kunye nokukhanya ngokufanelekileyo.
1. Indlela yokubala indawo yesikrini yesikrini sokubonisa i-LED
Indawo yesikrini yomboniso we-LED ibhekisela kubukhulu bendawo yokubonisa esebenzayo, ngokuqhelekileyo kwiimitha zesikwere. Ukubala indawo yesikrini yesiboniso se-LED, le parameters ilandelayo kufuneka yaziwe:
1. Isithuba samachaphaza: umgama osembindini phakathi kwepikseli nganye kunye neepikseli ezikufutshane, udla ngokuba ziimilimitha. Incinci inowuthi yechaphaza, iphezulu ingxinano ye-pixel, iphezulu isisombululo, icace ngakumbi isiphumo sokubonisa, kodwa ixabiso eliphezulu. I-pitch yechaphaza ngokubanzi imiselwa ngokweyona meko yesicelo kunye nomgama wokujonga.
2. Ubungakanani bemodyuli: imodyuli nganye ineepikseli ezininzi, eyona yunithi isisiseko yokubonisa i-LED. Ubungakanani bemodyuli bumiselwa linani leepikseli ezithe tyaba nezithe nkqo, ngokwesiqhelo kwiisentimitha. Umzekelo, imodyuli ye-P10 ithetha ukuba imodyuli nganye ineepikseli ezili-10 ngokuthe tye kwaye ngokuthe nkqo, oko kukuthi, 32×16=512 pixels, kunye nobukhulu bemodyuli yi-32×16×0.1=51.2 yeesentimitha zesikwere.
3. Ubungakanani beskrini: Umboniso wonke we-LED udityaniswe ngamamodyuli amaninzi, kwaye ubungakanani bayo buchongwa ngenani leemodyuli ezithe tye kunye nezithe nkqo, ngokuqhelekileyo kwiimitha. Ngokomzekelo, isikrini esigcwele umbala we-P10 kunye nobude beemitha ezi-5 kunye nobude beemitha ezi-3 kuthetha ukuba kukho iimodyuli ze-50 / 0.32 = 156 kwicala elithe tye kunye ne-30 / 0.16 = iimodyuli ze-187 kwicala elithe nkqo.
2. Indlela yokubala ukukhanya komboniso we-LED
Ukukhanya komboniso we-LED kubhekiselele kubukhulu bokukhanya obukhuphayo phantsi kweemeko ezithile, ngokuqhelekileyo kwi-candela ngemitha yesikwere (cd/m2). Ukuphakama kokukhanya, ukukhanya kunamandla, ukuphakama okuphezulu, kunye namandla okuchasana nokuphazamiseka. Ukuqaqamba ngokuqhelekileyo kumiselwa ngokwendawo eyiyo yesicelo kunye ne-angle yokujonga.
1. Ukukhanya kwesibane esisodwa se-LED: ukukhanya kokukhanya okukhutshwe ngumbala ngamnye wesibane se-LED, ngokuqhelekileyo kwi-millicandela (mcd). Ukukhanya kwesibane esisodwa se-LED kuchongwa yizinto zayo, inkqubo, yangoku kunye nezinye izinto, kunye nokukhanya kwezibane ze-LED zemibala eyahlukileyo nazo zihluke. Umzekelo, ukuqaqamba kwezibane ezibomvu ze-LED ngokuqhelekileyo yi-800-1000mcd, ukuqaqamba kwezibane eziluhlaza ze-LED ngokuqhelekileyo ziyi-2000-3000mcd, kunye nokuqaqamba kwezibane ze-LED eziluhlaza ngokuqhelekileyo ziyi-300-500mcd.
2. Ukuqaqamba kwepikseli nganye: Ipixel nganye yenziwe zizibane ezininzi ze-LED ezinemibala eyahlukeneyo, kunye nokukhanya kokukhanya okukhutshwa yiyo sisimbuku sokuqaqamba kombala ngamnye wokukhanya kwe-LED, ngokuqhelekileyo kwi-candela (cd) njengeyunithi. Ukukhanya kwepikseli nganye kumiselwa ngokubunjwa kunye nobungakanani bayo, kwaye ukuqaqamba kwepikseli nganye yeentlobo ezahlukeneyo zokubonisa i-LED nako kwahlukile. Umzekelo, ipixel nganye yesikrini esinemibala egcweleyo ye-P16 sinezibane ezi-2 ezibomvu, ezi-1 eziluhlaza, kunye ne-1 eluhlaza okwesibhakabhaka. Ukuba i-800mcd ebomvu, i-2300mcd eluhlaza, kunye ne-350mcd blue izibane ze-LED zisetyenziswa, ukuqaqamba kwepixel nganye yi (800×2 +2300+350)=4250mcd=4.25cd.
3. Ukukhanya okupheleleyo kwesikrini: ukukhanya kokukhanya okukhutshwe ngumboniso wonke we-LED sisimbuku sokukhanya kwazo zonke iipikseli ezahlulwe ngendawo yesikrini, ngokuqhelekileyo kwi-candela ngemitha yesikwere (cd / m2) njengeyunithi. Ukukhanya ngokubanzi kwesikrini kugqitywa sisisombululo saso, imodi yokuskena, ukuqhuba ngoku kunye nezinye izinto. Iindidi ezahlukeneyo zezikrini zokubonisa i-LED zinokuqaqamba okwahlukileyo. Umzekelo, isisombululo kwisikwere sesikrini esigcwele umbala we-P16 yi-3906 DOT, kwaye indlela yokuskena yi-1/4 yokuskena, ngoko ke ukuqaqamba kwayo kwethiyori (4.25×3906/4)=4138.625 cd/m2.
3. Isishwankathelo
Eli nqaku lizisa indlela yokubala indawo kunye nokukhanya kwesikrini sokubonisa i-LED, kwaye inika iifomyula ezihambelanayo kunye nemizekelo. Ngezi ndlela, iiparamitha ezifanelekileyo zokubonisa i-LED zingakhethwa ngokweemfuno kunye neemeko zangempela, kwaye umphumo wokubonisa kunye nokusebenza kakuhle kokugcina amandla kunokulungiswa. Ngokuqinisekileyo, kwizicelo ezisebenzayo, ezinye izinto kufuneka ziqwalaselwe, njengempembelelo yokukhanya kwe-ambient, iqondo lokushisa kunye nomswakama, ukutshatyalaliswa kobushushu, njl njl. ekusebenzeni kunye nobomi bomboniso we-LED.
Umboniso we-LED likhadi leshishini elihle kuluntu lwanamhlanje. Ayinakubonisa kuphela ulwazi, kodwa ikwadlulisa inkcubeko, idale umoya kunye nokuphucula umfanekiso. Nangona kunjalo, ukuze ufumane isiphumo esiphezulu somboniso we-LED, kuyimfuneko ukulawula iindlela ezithile zokubala ezisisiseko, ukuyila ngokufanelekileyo kwaye ukhethe indawo yesikrini kunye nokukhanya. Kuphela ngale ndlela sinokuqinisekisa umboniso ocacileyo, ukonga amandla, ukukhuselwa kwendalo, ukuqina kunye noqoqosho.
