Ungakwazi yini ukuthola i-Plasma TV?
Ngonyaka ka-2015, ukukhiqizwa kwe- Plasma TV kukhishwe emakethe yomthengi.
Kodwa-ke, kusekhona amanye abalandeli be-Plasma TV ngaphandle, nezigidi ze-Plasma TV zisasebenza. Lokhu kusho ukuthi labo abanama-Plasma TVs bangaqhubeka nokuwasebenzisa, kodwa labo abafuna ukuthenga i-TV ye-Plasma kuzodingeka baxazulule noma yikuphi ukuvulwa, ukuvuselelwa, noma amayunithi asetshenzisiwe angase atholakale ngokusebenzisa abathengisi abakhulu, amasayithi okudayiswa (njenge-eBay ), noma eminye imithombo efana ne-Amazon.com.
Yikuphi i-LCD ne-Plasma enayo evamile
Nakuba basebenzisa ubuchwepheshe obuhlukile ukubonisa izithombe esibukweni, i-LCD ne-Plasma bahlanganyela izinto ezithile ezivamile, kubandakanya:
- Ama-design panel amapaneli avumela ukuthi abe ngetafula noma udonga luphakanyisiwe.
- Izinhlobo ezifanayo zokukhethwa kokuxhumeka.
- Inganikeza ukukhetha okubukwa kwe-3D ekuboneni kwabakhiqizi be-TV.
- Izici ze-Smart TV nazo zinganikezwa kokubili njengoba lokho kuzimele kwezobuchwepheshe obusetshenziselwa ukubonisa izithombe esibukweni.
Izinzuzo ze-TV ePlasma
Ngaphezu kwalokho abelana ngakho, ama-Plasma TV anenzuzo ngaphezu kwe-LCD ezindaweni ezilandelayo:
- Isilinganiso sokungafani kakhulu .
- Ikhono elingcono lokubonisa abamnyama abanzi.
- Ukujula kombala nokubala okuningi.
- Isikhathi sempendulo yokusabela esithuthukisiwe kangcono) ngenxa yokuqaliswa kobuchwepheshe be-Sub Field Drive , nama-angles wokubuka okubanzi.
Ukukhubazeka kwe-TV yama-plasma
Izinkinga zePlasma vs LCD zihlanganisa:
- Ukumangalisa okungaphezulu ukushisa-ngaphakathi (nakuba lokhu akuyona into ebaluleke kakhulu kumamodeli wakamuva kakhulu ekuthuthukiseni ubuchwepheshe, njengokuthi "i-pixel ehamba phambili").
- Isizukulwane esiningi sokushisa (kanye nokusetshenziswa kwamandla amaningi).
- Ayenzi kahle ezindaweni eziphakeme.
- Ukukhanya kwe-image nokukhanya kwesikrini okukhanyayo emakamelweni akhanyayo.
- Isisindo esinzima (uma siqhathanisa ubukhulu bezinkrini ezilinganayo), futhi bunzima kakhulu ukuthumela.
Izinzuzo ze-LCD TV
Ama-TV e-LCD anenzuzo ngaphezu kwama-Plasma TV ezindaweni ezilandelayo:
- Ayikho i-pixel yokukhwabanisa-nakuba ukuphikelela okungapheli kwesinye isikhathi kubhekwa uma isithombe esifanayo sisesikrinini isikhathi eside.
- Ukushisa okushisa okushisa.
- Ngokujwayelekile unama-glare angaphansi kweskrini ngaphandle kokuthi isikrini sivinjiwe.
- Ukusebenza okuningi ezindaweni eziphezulu.
- Ukuphila okude isikhathi eside (nakuba igebe ivaliwe ezinhlobonhlobo zakamuva zama-Plasma TV).
- Kubonakala kungcono emakamelweni akhanyayo ngenxa yokwazi ukuveza isithombe esicacile ( okuvumela ukuqaliswa okungcono kwe-HDR ).
- Ukusebenzisa amandla okuncane.
- Isisindo somzimba ojwayelekile ngokuqhathanisa ubukhulu besikrini esifanayo.
- Nakuba kokubili ama-Plasma ne-LCD TV ayevame ukutholakala ngesinqumo sokubonisa isizwe sama-1080p, ngokufika kwe-4K, akukho nge-Plasma TVs eyethulwa ngekhono lokubonisa okungu-4K, ngaphandle kwamaqoqo aqokiwe amasiko namakhono ezimakethe.
- Nakuba kokubili ama-LCD nama-Plasma TV angenziwa ezinhlobonhlobo zobukhulu besikrini, amamodeli we-Plasma TV anezibuko zesikrini ezingaphansi kwamasentimitha angu-42 ayengavamile kakhulu, futhi ngakolunye uhlangothi lwama-equation, ayengavamile kakhulu kunama-intshi angu-65. Ngakho-ke, ngama-LCD ama-TV amaningi atholakalayo ngobukhulu bezinkrini ezincane njengezi-19-intshi ezingu-19 futhi ezinkulu njengama-intshi angu-90, lokho kubeka phambili isikhalazo se-Plasma TV.
Ukukhubazeka kwe-LCD TV
Kodwa-ke, yize i-LCD yesikhulumi se-TV ehlelwe ngePlasma ezindaweni ezihlukahlukene, kunezinye izici eziyinhloko ukuthi i-LCD ibenenkinga ngokuqhathanisa, njengama-Plasma televisions:
- Inani eliphansi lokuphambene .
- Akunjengoba kuhle ukubonisa abamnyama abajulile.
- I-angle yokubuka ngokubheke eceleni.
- Akusizi kahle ekuhambeni kokulandelela. Noma kunjalo, lokhu kuthuthukisiwe ngokusetshenziswa kwamazinga okuvuselela angu- 120Hz no-240Hz nokuqhutshwa kokunyakaza okungeziwe, kodwa futhi kubangelwa umshini obizwa ngokuthi "I-Soap Opera" umphumela lapho okuqukethwe kwefilimu kubonakala sengathi kufana nevidiyo kunefilimu.
- Nakuba ama-TV e-LCD awahluleki ukushisa, kungenzeka ukuthi amaphikseli ngamanye ama-TV e-LCD angashisa, okwenza amachashazi amancane, abonakalayo, abamnyama noma amhlophe avele esibukweni. Amaphikseli angeke akwazi ukulungiswa, sonke isikrini sidinga ukushintshwa ngaso leso sikhathi uma ukucindezeleka kwamaphikseli ngamunye kukucasula kuwe.
- Eminyakeni yamuva kuze kube sekupheleni kokukhiqizwa kwe-TV ye-Plasma, ama-TV e-LCD amakhulu e-screen ngokuvamile ayebiza kakhulu kune-Plasma TV elinganayo.
I-Mercury Issue
Impikiswano eyodwa yokuthi abakhiqizi be-Plasma TV abenziwe nge-TV ye-LCD eminyakeni eyadlula ukuthi i-platform ye-LCD incike ekusebenziseni ubuchwepheshe bendabuko be-backlight ukuze kukhanyise ubuso besikrini, futhi, ngaleyo ndlela, basebenzise i-Mercury njengengxenye yokwenziwa kwamakhemikhali kwesistimu ye-backlight fluorescent.
Kodwa-ke, lokhu "ukuphilisa okubomvu" mayelana nokukhetha i-Plasma TV phezu kwe-TV ye-LCD njengoba inani leMercury elisetshenziselwa amanye ama-TV e-LCD akuyona encane nje kuphela, ayihlangatsheki noxhumana nomsebenzisi. Futhi, khumbula ukuthi izibani ezivame kakhulu ezibonakalayo eziphezulu kakhulu, njengezinhlobo eziningi ezisetshenziselwa ama- video projects , kanye nezibani "eziluhlaza" sonke kufanele sithathe indawo yethu yokukhanya yendabuko futhi isebenzise i-Mercury.
Cishe usengozini enkulu yokudla izinhlanzi, ezingase zibe nezinhlamvu zeMercury, izikhathi ezimbalwa ngesonto, kunokuba ubuke, uthinte noma usebenzise i-LCD TV. Ngakolunye uhlangothi, ngokusetshenziswa kakhudlwana kwemithombo yokukhanyisa kwe-LED kuma-TV amaningi e-LCD okwenziwa kusukela ngo-2012 futhi, kusukela ngo-2016 cishe wonke ama-TV e-LCD asebenzisa ukukhanya kabusha kwe-LED, okuwumthombo wokukhanya wama-Mercury.
Ukuze uthole imininingwane eminingi ekusebenziseni ukukhanyisa kwe-LED kuma-TV e-LCD, bhekani esihlokweni somngane wethu: Iqiniso Ngama-TV "I-LED" .
Amaphuzu we-Quantum
Esinye isandulela esihlanganisiwe esiteshini se-LCD TV yikusetshenziswa kwe- Quantum Dots . Kusukela ngo-2018, i-Samsung ne-TCL inikeza lobu buchwepheshe ngaphansi kwelebuli "QLED" ekukhetheni ama-TV aphezulu ekupheleni kwemikhiqizo yawo. I-Quantum Dots ivumela i-LED / i-LCD TV ukuba ikhiqize imibala eminingi egcwele, enembile kunangaphambili eyayingenzeka.
I-3D
Esinye isici se-LCD ne-Plasma TV ukuthi amanye ama-TV e-3D e-LCD asebenzisa uhlelo lokubukwa kwe-Active Shutter, kanti amanye ama-TV e- 3D e-LCD asebenzisa isimiso sokubukwa esincane se-Passive, enikeza umthengi ithuba lokuzikhethela uma ecubungula inketho yakho yokubuka i-3D ekhethiwe. Nokho, i-3D Plasma TVs, uhlelo olusebenzayo kuphela lokusinda lusebenza. Ukuze uthole imininingwane eyengeziwe mayelana nokuthi kusho ukuthini ukuthenga noma ukusebenzisa isinqumo, funda i-reference yami ye-reference: Yonke Mayelana Nezibuko Ze-3D - I-Active vs Passive .
Noma kunjalo, kubalulekile ukuqaphela ukuthi inketho yokubukwa kwe- 3D TV inqatshiwe ngo-2017 . Noma kunjalo, ama-video amaningi ama-projectors ahlinzeka ngale ndlela.
I-Alternative TV ye-OLED
Ngaphandle kwe-LCD, amathelevishini asebenzisa ubuchwepheshe be- "OLED" nawo ayatholakala manje . Lolu buchwepheshe lunikezwe abathengi njengenye yokukhetha ukuthenga i-TV kodwa kunomkhawulo kakhulu ekukhethweni nasekutholakaleni, kanye nentengo. Emakethe yase-US, ama-OLED TV anikezwa yi-LG ne-Sony.
Okuthakazelisayo ngama-TV e-OLED ukuthi bahlanganisa izinzuzo zombili i-Plasma ne-LCD. Amaphikseli we-OLED TV ayenzayo, njengama-phosphors asetshenziswe kuma-Plasma TV, futhi angaveza umbala ocacile, futhi ama-TV angenziwa omncane kakhulu, njengama-TV e-LCD (kuphela alula kakhulu!). Ama-TV e-OLED nawo ayengama-TV wokuqala okuzokwenziwa ngawo wonke ama-skrini angama-flat and curved - nakuba abanye abakhiqizi beye balandela i-LCD eyodwa ye-TV eyodwa. Ohlangothini olungalungile, ama-TV e-OLED angathola ukushisa noma ukuphikiswa kwesithombe futhi kungaba nempilo emifushane kunama-TV e-LCD.
Okubalulekile
Isinqumo sokugcina sokuthi luhlobo luni lwe-TV okumele lithenge luye kuwe. Kodwa-ke, lapho sake sakwazi ukukhetha i- CRT, i-Projection yangemuva, i-LCD, ne-Plasma, okuwukuphela kokukhetha okukhona manje kuyi-LCD ne-OLED .
Noma yikuphi ukuthengwa kwe-TV, iya kumthengisi futhi ubuke ngokucophelela izinhlobo ze-TV ezitholakalayo futhi uqhathanise ukusebenza, izici, ukulula ukusetshenziswa, nokuxhuma , futhi unciphise izinqumo zakho kokubili noma ezimbili zombili izinhlobo futhi wenze isinqumo sakho sisekelwe kulohlobo olunikeza isithombe esihle kakhulu, uxhumano lokuguquguquka, futhi luhambisana nezilindelo zakho zebhajethi jikelele.
Kusukela ngo-2016, i-LCD ne-OLED yiwona kuphela okukhethwa kukho okubonakalayo okubukwayo okubandakanya i-TV (ama-video weprojekti yinye indlela). Ngeshwa, ngaphandle kokuthi usebenzise, ama-Plasma TV ayatholakali.
