Yintoni ukuKhanya kweSkrini se-LED?
Ukukhanya kwesikrini sokubonisa i-LED kubhekiselele kubukhulu bokukhanya okukhutshwa zii-LED zayo zangaphakathi (I-Light Emitting Diodes). Ngokuqhelekileyo, sisebenzisa i-cd/m² (icandela ngemitha yesikwere) okanye oonomoyi njengeeyunithi zokulinganisa ukuqaqamba kwesikrini se-LED. Ukunyuka kwexabiso lokukhanya kubonisa ukuba umboniso we-LED ukhupha ukukhanya okunamandla. Umzekelo, isikrini se-LED sangaphandle esine-10,000 ye-nits yokuqaqamba sikhanya ngakumbi kunesikrini se-LED sangaphakathi esine-800 yee-nits kuphela.
Ukubaluleka kokuKhanya kweSkrini se-LED
Ukuziqhelanisa neemeko ezahlukeneyo
Ukukhanya kwesikrini se-LED kubalulekile ekuziqhelaniseni neemeko ezahlukeneyo. Ukukhetha inqanaba lokukhanya elichanekileyo akuqinisekisi kuphela ukuhambelana nokusingqongileyo kodwa kwandisa ukusebenza kakuhle kwezoqoqosho kwesikrini se-LED.
Impembelelo kwiNtsebenzo iyonke
Ukukhanya kuchaphazela kakhulu ezinye izalathisi zokusebenza zesikrini se-LED, ezifana nochasaniso, i-grayscale, kunye ne-vibrancy yombala. Ukukhanya okungonelanga kuchaphazela ngokuthe ngqo ukusebenza kwesikrini kwezi ndawo, nto leyo emisela ubukhulu becala ubulunga besiboniso se-LED.
I-engile yokujonga ehambelanayo
Ukukhanya okuphezulu kuvumela ukucaca komfanekiso okuhambelanayo kwi-engile yokujonga ngokubanzi. Oku kuthetha ukuba nangona xa kujongwa kwii-angles ezingekho phakathi, ukukhanya okuphezulu kwesikrini se-LED kunokuqinisekisa umboniso ocacileyo womxholo, kanti isikrini esikhanyayo sinokuba nzima ukugcina ukucaca ukusuka emaphethelweni.
Uluhlu olubanzi lwezicelo
Izikrini ze-LED ezikhanyayo ezinoluhlu olubanzi lwezicelo, ezifanelekileyo kwiindawo ezinjengeevenkile zokuthengisa, ii-airports, iindawo zezemidlalo, kunye neendawo zokuhamba ezifuna ukubonakala okuphezulu kunye nomgangatho wesithombe. Ngokwahlukileyo, izikrini zokukhanya okuphantsi kwe-LED zihlala zilinganiselwe kwiindawo ezingaphakathi okanye ezikhanyayo.
Indlela yokumisela ukuKhanya kweSkrini se-LED esifanelekileyo
Ngelixa ukukhanya okuphezulu kuyinzuzo enkulu kwizikrini ze-LED, ikwaza neendleko eziphezulu. Ngoko ke, xa uthenga isikrini se-LED, kubalulekile ukuqwalasela izinto ezinjengendawo yokufakela kunye nodidi lomxholo oza kuboniswa ukwandisa ukusebenza kakuhle kweendleko. Kwangaxeshanye, kuphephe ukukhetha ukukhanya okuphakame kakhulu ngaphandle kokuba kuyimfuneko ukuthintela iindleko ezingeyomfuneko.
Qwalasela iNdawo yokuFakelo xa ukhetha ukuKhanya kweSkrini se-LED
Ngokuqhelekileyo, ukuqaqamba kwezikrini ze-LED zangaphakathi kufuneka zihambe phakathi kwe-800 kunye ne-2500 nits, kuxhomekeke kumanqanaba okukhanya okungqongileyo kwendawo yangaphakathi. Ezinye iindawo zangaphakathi zisenokukhanya luzizi, ngoxa ezinye zinokubonakala ziqaqambile ngenxa yokukhanya kwelanga okusefa ngeendonga zeglasi, iifestile, okanye ezinye izakhiwo.
Kwizikrini ze-LED zangaphandle, iimfuno zokukhanya zihluka kakhulu ngokuxhomekeke kwindawo kunye nexesha:
- Kwiindawo ezingaphandle ezinomthunzi, ukukhanya kwesikrini se-LED kufuneka kubekwe phakathi kwe-2500 kunye ne-4000 nits;
- Kwiindawo ezingaphandle ngaphandle kwelanga elithe ngqo, ukukhanya okufanelekileyo kwesikrini se-LED kuphakathi kwe-3500 kunye ne-5500 nits;
- Ngokukhanya kwelanga, ukukhanya kwesikrini se-LED kufuneka kudlule ii-nits ze-5500 ukuqinisekisa ukuba ulwazi lubonakala ngokucacileyo.
Kubalulekile ukuqaphela ukuba la maxabiso aqaqambileyo zizikhokelo kuphela. Enyanisweni, ukukhanya kwe-ambient kwiindawo ezahlukeneyo kunokwahluka kakhulu. Ke ngoko, kuyacetyiswa ukuba umisele obona kukhanya kufanelekileyo kwesikrini se-LED ngokuhlolwa kwendawo okanye uvavanyo ngaphakathi kolu luhlu lucetyiswayo. Ukongeza, ukufuna iingcebiso zobuchwephesha kubaqhubi besikrini se-LED abanamava okanye ababoneleli kunokuba luncedo.
Impembelelo yeSimbo soMxholo kuBukhanye beSkrini se-LED
Inqanaba lokukhanya elifunekayo lesikrini se-LED linokwahluka ngokuxhomekeke kuhlobo lomxholo oboniswayo, ngakumbi kwizicelo zangaphakathi:
- Izikrini ze-LED ezibonisa ulwazi olulula lwesicatshulwa, izinga lokukhanya kwe-200 ukuya kwi-300 nits yanele;
- Kumxholo wevidiyo jikelele, ukukhanya kwesikrini se-LED kufuneka kube phakathi kwe-400 kunye ne-600 nits;
-Ukwenzela intengiso, ngakumbi umxholo ofuna isibheno esibonakalayo esinamandla, ukukhanya kwesikrini se-LED kufuneka kunyuswe ukuya kuma-600 ukuya kwi-1000 nits.
Ukuqukumbela
Ngokubanzi, ukukhanya yinto ephambili ekuqinisekiseni ukucaca komxholo wesikrini se-LED, ukuphucula umgangatho womfanekiso, kunye nokudala impembelelo ebonakalayo. Izikrini ze-LED zinenzuzo enkulu ekukhanyeni ngaphezu kobunye ubugcisa bokubonisa, okwenza ukuba zilungele uluhlu olubanzi lwezicelo. Nangona kunjalo, xa ukhetha isikrini se-LED, kubalulekile ukuqwalasela izinto ezahlukeneyo zokuqinisekisa ukuba ukukhanya okukhethiweyo kuyahlangabezana neemfuno zesicelo esisebenzayo ngelixa ulungiselela umlinganiso wokusebenza kweendleko zesikrini se-LED.
