I-LCD ne-Plasma TV zibukeka sengathi zingaphandle, kodwa zihlukile ngaphakathi
Ngo-2015, ukukhiqizwa kwe- Plasma TV kuphelile. Noma kunjalo, eziningi zisasetshenziswa futhi zithengiswa emakethe yesibili. Ngenxa yalokho, ukuqonda ukuthi i-Plasma TV isebenza kanjani nokuthi ikufanisa kanjani ne-TV LCD kubalulekile.
I-Plasma ne-LCD TV: Efanayo, Kodwa Ehlukile
Ukubonakala kwangaphandle kuyakhohlisa ngokuqondene ne-LCD ne-Plasma TVs.
I-Plasma ne-LCD TV ziyizicabha futhi zizincane, futhi zingase zihlanganise nezinye izici ezifanayo. Zombili izinhlobo zingadala udonga futhi zinganikela nge -intanethi nokusakaza kwenethiwekhi yasendaweni , bobabili banikela ngezinhlobo ezifanayo zokukhethwa kokuxhumana ngokomzimba, futhi-ke, kokubili kokuvumela ukubuka izinhlelo ze-TV, ama-movie, nokunye okuqukethwe ezihlukahlukene kwesikrini ubukhulu kanye nezinqumo. Kodwa-ke, ukuthi bakhiqiza kanjani futhi babonise lezo zithombe empeleni bahluke kakhulu.
Yeka ukuthi ama-Plasma TVs asebenza kanjani
Ubuchwepheshe be-TV e-Plasma busekelwe ngokungahambisani ne-bulb light fluorescent. Isibonisi ngokwazo sakhiwa ngamaseli. Ngaphakathi kweseli ngayinye ama-panels amabili e-glass ahlukaniswa i-gap encane ehlanganisa uhlaka lokuvimba, ikheli le-electrode, kanye ne-electrode yokubonisa, lapho i-neon-xenon gas igonywa khona futhi ifakwe ifomu le-plasma ngesikhathi sokukhiqiza.
Uma i-Plasma TV isetshenziswa, igesi iyakhipha umshini kagesi ngezikhathi ezithile. Igesi elikhokhiswayo libhekene ne-phosphors ebomvu, eluhlaza okwesibhakabhaka nohlaza okwesibhakabhaka, ngaleyo ndlela yakha isithombe esikrinini se-Plasma TV. Iqembu ngalinye le-phosphors elibomvu, eliluhlaza neluhlaza okwesibhakabhaka libizwa ngokuthi i- pixel (isici sezithombe - i-phosphors ebomvu, eluhlaza, neluhlaza okwesibhakabhaka kuthiwa yi-sub-pixels) . Njengoba amaphikseli e-Plasma TV enza ukukhanya kwawo, abizwa ngokuthi "ukubonisa" okubonisa.
Ngenxa yokuthi i-Plasma TV isebenza kanjani, ingenziwa encane kakhulu. Kodwa-ke, yize kudingeka isidingo se-picture esibucayi ne-electron beam ukuskena kwalawo ma-TV asebekhulile akusadingeki, ama-Plasma TV asebenzisa ama-phosphors ashisa ukwenza isithombe. Ngenxa yalokho, ama-Plasma TV abhekana nokunye kokushiyeka kwe-TV ye-CRT yendabuko, njengesizukulwane sokushisa kanye nokushisa kwesikrini okungenzeka ku-static images.
Indlela ama-TV e-LCD asebenza ngayo
Ama-TV e-LCD asebenzisa ubuchwepheshe obuhlukile kuno-plasma ukubonisa isithombe. Amapaneli e-LCD akhiwe ngezigaba ezimbili zento ebonakalayo, ekhonjiswa, futhi "ihlanganiswe" ndawonye. Enye yalezi zigaba ziboshwe nge-polymer ekhethekile ephethe amakristalu ekhemikhali. Okwamanje idluliselwa ngama-crystals ngamanye, evumela ukuthi amakristalu adlulise noma avimbele ukukhanya ukudala izithombe.
Ama-crystals e-LCD awakhiqizi ukukhanya kwawo, ngakho-ke umthombo wokukhanya wangaphandle, okufana ne-fluorescent (CCFL / HCFL) noma ama-LED adingekayo ukuze isithombe esenziwe i-LCD sibonakale kumbukeli. Kusukela ngo-2014, cishe wonke ama-TV e-LCD asebenzisa izibuko ze-LED. Njengoba ama-crystals e-LCD awakhiqizi ukukhanya kwawo, ama-TV e-LCD abizwa ngokuthi "okudluliselayo" ukubonisa.
Ngokungafani ne-TV ye-Plasma, njengoba kungekho phosphors ekhanyayo, amandla amancane adingekayo ukusebenza futhi umthombo wokukhanya ku-LCD TV kudala ukushisa okungaphansi kwe-Plasma TV. Futhi, ngenxa yemvelo yobuchwepheshe be-LCD, ayikho imisebe ekhishwe esikrinini ngokwayo.
IZINHLOKO ZEMPlasma phezu kwe-LCD
- Ukulinganiswa okungcono kokulinganisa kanye nekhono lokunikeza abamnyama abajulile.
- Ukunemba kombala nokugcwala.
- Ukulandela okuhamba phambili okungcono (ukuhamba okuncane noma okungenayo akukho okuhambayo ezithombeni ezihamba ngokushesha ngenxa yokusetshenziswa kobuchwepheshe be- Sub Field Drive ).
- I-angle yokubuka ehlangothini olubanzi.
IZINDABA ZEMPlasma vs LCD
- I-TV yama-plasma ayibonakali njengama-TV amaningi e-LCD. Ama-TV e-Plasma enza kangcono ekamelweni elincane elikhanyisiwe noma elimnyama.
- Isikrini sesibonakaliso sibonakala ngaphezulu kunezingcingo eziningi ze-LCD. Okunye okungaqondakali ukukhanya kwe-glare - kwesikrini kubonisa imithombo emincane yokukhanya.
- Ama-TV e-plasma angakwazi ukushisa-ngaphakathi kwezithombe eziqinile. Kodwa-ke, le nkinga iyancipha kakhulu eminyakeni yamuva nje ngenxa yokufaka "i-pixel orbiting" kanye nobuchwepheshe obuhlobene.
- Ama-TV e-Plasma enza ukushisa okukhulu futhi asebenzise amandla amaningi kunama-TV e-LCD, ngenxa yesidingo sokukhanya kwe-phosphors ukwakha izithombe.
- Ayenzi kahle ezindaweni eziphakeme.
- Kungenzeka ukuthi kufushane ukubonisa isikhathi sokuphila - lokhu kwakuvame ukuba njalo. I-Plasmas yasekuqaleni yayineamahora angu-30 000 noma amahora angu-8 wokubuka usuku iminyaka engu-9, engaphansi kweLCD. Kodwa-ke, isikhathi sokuphila kwesikrini sesithuthukile futhi isilinganiso sokuphila samahora angu-60,000 manje sesivamile, kanti ezinye isethi zilinganiselwe ngamahora angu-100,000, ngenxa yokuthuthukiswa kwezobuchwepheshe.
KUFANELE I-LCD ngaphezu kwe-Plasma TV
- Akukho ukushisa kwezithombe eziqinile.
- Ukushisa okushisa okushisa.
- Azikho izinkinga zokusebenzisa eziphezulu kakhulu.
- Ukwenyuka kokukhanya kwesithombe ngaphezu kwe-Plasma, okwenza ama-TV e-LCD angcono ekubukeni ekamelweni elikhanyayo.
- Ukubukeka kweskrini kuma-TV amaningi e-LCD akubonakali kancane kunezibuko zesikrini se-Plasma TV, okwenza kube lula ukukhanya kwesikrini.
- Isisindo esilula (lapho siqhathanisa ubukhulu besikrini esifanayo) kunama-Plasma counterparts.
- Ukuphila okude isikhathi eside, kodwa igebe liye lancipha.
- Ku-3D, nge-LCD unenketho phakathi kwamayunithi asebenzisa i- Active Shutter ne-Glass Passive , kuyilapho ama-TV e-3D Plasma kuphela asebenzisa uhlelo lwe-Active Shutter Glasses.
IZINDAWO ZOKWENZA LCD vs Plasma TV:
- Ukulinganisa okungokoqobo okungezansi, hhayi okuhle ukunikeza abamnyama abajulile, nakuba ukuhlanganiswa okwandayo kokubuyiselwa kwe-LED kuye kwanciphisa le geba.
- Akuyona into ehamba phambili ekuhambeni kokulandelela (izinto ezihamba phambili ezihamba ngokushesha zingabonisa izinto zokufakelwa kwe-lag) - Nokho, lokhu kuthuthukiswa nokusetshenziswa kwamuva kwezinga le- 120Hz lokuvuselelwa kwesikrini nokucubungula kwe-240Hz kumaqoqo amaningi e-LCD, kodwa lokho kungaholela "ku-Opera Effect Effect", lapho imithombo yokuqukethwe efilimu ibukeka ifana nevidiyo yefilimu.
- I-angle ebonakalayo ebonakalayo ebonakalayo ehlangene kune-Plasma. Ku-TV ye-LCD, kuvamile ukuqaphela ukugqama kombala noma ukushintsha umbala njengoba uhambisa isikhundla sakho sokubuka ngokuya ngaphesheya kwephuzu lesikhungo.
- Nakuba ama-TV e-LCD ahlukumezeki ngokushisa, kungenzeka ukuthi amaphikseli athile kumathelevishini e-LCD angashisa, okwenza amachashazi amancane, abonakalayo, amnyama noma amhlophe avele esibukweni. Amaphikseli angeke akwazi ukulungiswa, sonke isikrini sidinga ukushintshwa ngaso leso sikhathi uma ukucindezeleka kwamaphikseli ngamunye kukucasula kuwe.
- I-LCD TV ivame kakhulu kunezilinganiso ezilingana (futhi ezilinganayo ezibonakalayo) I-Plasma TV, nakuba lokho akuseyona inkinga, manje ukuthi ama-Plasma TVs anqanyuliwe.
I-Factory ye-4K
Okunye okunye okumele kuvezwe mayelana nokuhluka phakathi kwe-LCD ne-Plasma TV, yilokho okwakungeniswa lapho kuqaliswa ama-4K Ultra HD TV , abakhiqizi be-TV benza ukhetho ukwenza kuphela isinqumo esingu-4K esitholakalayo kuma-TV e-LCD, besebenzisa i-LED emuva nokukhanyisa ukukhanya, futhi, esimweni se-LG ne-Sony, futhi ihlanganisa 4K kumathelevishini usebenzisa ubuchwepheshe be-OLED .
Yize kungenakwenzeka ukukhiqiza futhi kufaka ukukwazi ukubonisa ukulungiswa kwe-4K ku-Plasma TV, kubiza kakhulu ukwedlula lokho ku-platform ye-LCD TV, futhi, ngokudayiswa kwe-TV yama-Plasma eqhubeka nokwehla eminyakeni edlule, abenzi be-TV yama-Plasma wenza isinqumo sebhizinisi sokungenisa amathekisthi angama-4K Ultra HD Plasma TV emakethe, okwakuyisinye isici ekufeni kwabo. Ama-TV kuphela ama-4K Ultra HD ama-Plasma ayenziwe / akhiqizwa asebenza kuphela ekusetshenzisweni kwezebhizinisi.
Okubalulekile
I-Plasma inendawo evelele emlandweni we-TV njengoba ubuchwepheshe obuqalile umkhuba obheke iphaneli flat, i-Hang-on-the-wall TV, nedivaysi yokubonisa ividiyo eyayithembisiwe kusukela ekuqaleni kwawo-1950. Ethuthukisiwe eminyakeni engaphezu kwengu-50 eyedlule, ukusebenza kwayo nokuziwayo kwavela eminyakeni eyishumi leminyaka yekhulu lama-21 kodwa manje sekudluliselwe kwiGadget Heaven ngenxa yokuthuthukiswa kwezobuchwepheshe be-LCD TV nokufakwa kwama-TV e-OLED, avimbele igebe namanye izinzuzo uPlasma TV ezinikezile.
Ukubukeka okuningiliziwe kokufaniswa kwe-LCD ne-Plasma TV, futhi ufunde: Kufanele Ngithenge i-LCD noma i-Plasma TV? .
