Sivamise ukuzwa amagama athi "4K" kanye "OLED" ezimpilweni zethu zansuku zonke, ikakhulukazi uma siphequlula ezinye izinkundla zokuthenga ku-inthanethi. Izikhangiso eziningi zama-monitor noma ama-TV zivame ukusho la magama amabili, okuqondakalayo futhi okudidayo. Okulandelayo, ake sibheke ngokujulile.
Yini i-OLED?
I-OLED ingathathwa njengenhlanganisela yobuchwepheshe be-LCD ne-LED. Ihlanganisa ukwakheka okuncane kwe-LCD kanye nezici ezizikhanyisayo ze-LED, kuyilapho isebenzisa amandla aphansi. Isakhiwo sayo sifana ne-LCD, kodwa ngokungafani ne-LCD nobuchwepheshe be-LED, i-OLED ingasebenza ngokuzimela noma njenge-backlight ye-LCD. Ngakho-ke, i-OLED isetshenziswa kakhulu kumadivayisi amancane naphakathi afana nomakhalekhukhwini, amaphilisi nama-TV.
Yini i-4K?
Emkhakheni wobuchwepheshe bokubonisa, ngokuvamile kukholakala ukuthi amadivayisi wokubonisa angafinyelela amaphikseli angu-3840 × 2160 angabizwa nge-4K. Lesi sibonisi sekhwalithi singaletha isithombe esithambile nesicacile. Njengamanje, izinkundla eziningi zamavidiyo aku-inthanethi zihlinzeka ngezinketho zekhwalithi engu-4K, okuvumela abasebenzisi ukuthi bajabulele umuzwa wevidiyo wekhwalithi ephezulu.
Umehluko phakathi kwe-OLED ne-4K
Ngemva kokuqonda lobu buchwepheshe obubili, i-OLED ne-4K, kuyathakazelisa ukubuqhathanisa. Uyini-ke umehluko phakathi kwalokhu okubili?
Eqinisweni, i-4K ne-OLED imiqondo emibili ehlukene: I-4K ibhekisela ekulungisweni kwesikrini, kuyilapho i-OLED iwubuchwepheshe bokubonisa. Zingaba khona ngokuzimela noma zihlangene. Ngakho-ke, kubalulekile ukuqonda ukuthi lezi zibili zihlangene kanjani.
Kalula nje, inqobo nje uma idivayisi yokubonisa inokulungiswa kwe-4K futhi isebenzisa ubuchwepheshe be-OLED, singayibiza ngokuthi "4K OLED".
Eqinisweni, imishini enjalo ngokuvamile iyabiza. Kubathengi, kubaluleke kakhulu ukucabangela isilinganiso sokusebenza kwentengo. Esikhundleni sokukhetha umkhiqizo obizayo, kungcono ukhethe idivayisi engabizi kakhulu. Ngemali efanayo, ungajabulela okuhlangenwe nakho okuseduze ngenkathi ushiya isabelomali esithile ukuze ujabulele ukuphila, njengokubuka ifilimu noma ukudla okumnandi. Lokhu kungase kukhange nakakhulu.
Ngakho-ke, ngokombono wami, kunconywa ukuthi abathengi bacabangele abaqaphi abajwayelekile be-4K esikhundleni se-4K OLED monitors. Siyini isizathu?
Inani Yebo isici esibalulekile. Okwesibili, kunezinkinga ezimbili okufanele uzinake: ukuguga kwesikrini nokukhethwa kosayizi.
Inkinga yokushiswa kwesikrini se-OLED
Sekuyiminyaka engaphezu kwengu-20 ubuchwepheshe be-OLED bethulwa okokuqala, kodwa izinkinga ezifana nokuhluka kombala nokushiswa ngaphakathi azikaxazululwa ngempumelelo. Ngenxa yokuthi iphikseli ngayinye yesikrini se-OLED ingakhipha ukukhanya ngokuzimela, ukwehluleka noma ukuguga ngaphambi kwesikhathi kwamanye amaphikseli kuvame ukuholela ekubonisweni okungavamile, okubuye kukhiqize lokho okubizwa ngokuthi isenzakalo sokushiswa. Le nkinga ngokuvamile ihlobene eduze nezinga lenqubo yokukhiqiza kanye nokuqina kokulawulwa kwekhwalithi. Ngokuphambene, izibonisi ze-LCD azinazo izinkinga ezinjalo.
Inkinga kasayizi we-OLED
Kunzima ukwenza izinto ze-OLED, okusho ukuthi ngokuvamile azenziwanga zibe zinkulu kakhulu, ngaphandle kwalokho zizobhekana nokwenyuka kwezindleko kanye nezingozi zokwehluleka. Ngakho-ke, ubuchwepheshe bamanje be-OLED busasetshenziswa kakhulu kumadivayisi amancane afana nomakhalekhukhwini namathebulethi.
Uma ufuna ukwakha i-TV yesikrini esikhulu esingu-4K ngesibonisi se-LED, lokhu kuyisinqumo esihle. Inzuzo enkulu yezibonisi ze-LED ekwenzeni ama-TV e-4K ukuguquguquka kwawo, futhi osayizi abahlukene nezindlela zokuwafaka zingasikwa ngokukhululekile. Njengamanje, izibonisi ze-LED zihlukaniswe ngokuyinhloko zibe izinhlobo ezimbili: imishini yonke-in-one kanye nezindonga ze-LED zokuhlanganisa.
Uma kuqhathaniswa nama-TV e-4K OLED ashiwo ngenhla, intengo yezibonisi ze-LED ze-in-one iyathengeka kakhulu, nosayizi mkhulu, futhi ukufakwa kulula futhi kulula.
Izindonga zevidiyo ze-LEDzidinga ukwakhiwa ngesandla, futhi izinyathelo zokusebenza ziyinkimbinkimbi kakhulu, ezifaneleka kakhulu kubasebenzisi abajwayelene nokusebenza ngezandla. Ngemva kokuqeda ukwakha, abasebenzisi badinga ukulanda isofthiwe efanele yokulawula i-LED ukuze basuse iphutha esikrinini.
