I-LCD ne-Plasma TV zibukeka zifana nangaphandle, kodwa zihluke ngaphakathi
Ngo-2015, ukuveliswa kwe- TV ye-Plasma kuphelile. Nangona kunjalo, ezininzi zisasetyenziswa kwaye zithengiswa kwimarike yesibini. Ngenxa yoko, ukuqonda indlela esebenza ngayo i-Plasma TV kunye nendlela efanisa ngayo i-LCD TV kubalulekile.
I-Plasma kunye ne-LCD TV: Efanayo, kodwa eyahlukileyo
Ukubonakala kwangaphandle kukukhohlisa xa kufike kwiLCD kunye ne-Plasma TV.
Iimvumi ze-Plasma kunye ne-LCD zithe tye kwaye zincinci, kwaye zinokubandakanya ezininzi iimpawu ezifanayo. Zombini iintlobo zinokuba udonga lubekwe kwaye lunokunikezela nge -intanethi kunye nokuthungelwano kwenethiwekhi yasekuhlaleni , zombini zinikeza iinkalo ezifanayo zokunxibelelanisa ngokoqobo, kwaye ke, zombini zombini ikuvumela ukuba ubukele iinkqubo zeTV, ii-movie kunye nezinye iziqulatho kwiinkalo ezahlukeneyo. ubukhulu kunye nezigqibo. Nangona kunjalo, indlela abavelisa ngayo kwaye babonise loo mifanekiso ihluke ngokwenene.
Indlela I-Plasma TVs Work
Ubuchwephesha beTV ye-TV busekelwe ngokukhululekile kwi-bulb light light. Umboniso ngokwawo uqukethe iiseli. Ngaphakathi kweseli nganye iiplastiki ezimbini zihlukaniswe ngendawo encinci ekubandakanyekeni, i-address electrode, kunye ne-electrode, apho i-neon-xenon igesi ifakwe kwaye ifakwe uphawu kwifom ye-plasma ngethuba lokuvelisa.
Xa i-TV ye-Plasma isetyenziswa, igesi ihlawuliswa ngombane ngexesha elithile. Igazi ehlawulwayo ibetha i-phosphors ebomvu, eluhlaza, kunye ne-blue, ngaleyo ndlela idala umfanekiso kwi-screen ye-Plasma TV. Iqela ngalinye le-phosphors ebomvu, eluhlaza, kunye ne-blue libizwa ngokuba yi- pixel (into ebonakalayo ebomvu, i-phosphors ebomvu, eluhlaza kunye ne-blue) . Ekubeni iiplaseli ze-Plasma zeTV zivelisa ukukhanya kwazo, zibizwa ngokuba yi-"emissive".
Ngenxa yendlela esebenza ngayo i-TV ye-Plasma, ingaba yincinci. Nangona kunjalo, nangona kudingeke ukuba kusetshenziswe ithubhu yesikhombiso kunye ne-electron ukukhangela kwee-TV ze-CRT ezindala, ii-Plasma TV zisasebenzisa i-phosphors evuthayo ukuvelisa umfanekiso. Ngenxa yoko, ii-Plasma TV ziyakhathazeka ngezinye zeengxaki ze-TV ze-CRT zendalo, ezifana nokuvelisa ukushisa kunye nokukhangela kwesikrini.
Indlela i-LCD TVs isebenza ngayo
I-TV yeLCD isebenzisa iteknoloji eyahlukeneyo kuneplasma ukubonisa umfanekiso. Iipaneli zeLCD zenziwe ngamacwecwe amabini obala, ahlongozwayo, kwaye "ahlanganiswe" ndawonye. Esinye seziqendu sinxibe ngepolymer ekhethekileyo ephethe amakhemikhali. Ixesha langoku lidlulelwa ngamakristal ahlukeneyo, avumela ukuba amakristali adlule okanye avimbe ukukhanya ukudala imifanekiso.
I-crystals ye-LCD ayivelisi ukukhanya kwayo, ngoko ke umthombo wokukhanya wangaphandle, onjenge-fluorescent (CCFL / HCFL) okanye ii-LED ezifunekayo ukuze umfanekiso owenziwe yi-LCD ukuba ibonakale kumbukeli. Ukususela ngo-2014, phantse yonke i-TV ye-LCD isebenzisa i-LED. Ekubeni ama-crystals e-LCD awavelisi ukukhanya kwawo, ii-LCD TV zibizwa ngokuba "zibonakaliso" zokubonisa.
Ngokungafani neTV ye-Plasma, ekubeni akukho phosphors ekhanyayo, amandla angaphantsi afunekayo ukuze asebenze kwaye umthombo wokukhanya kwi-LCD TV ivelisa ubushushu obuncinane kuneTlasma yeTlasma. Kwakhona, ngenxa yobume be-teknoloji yeLCD, akukho mijelo ephuma kwisikrini ngokwazo.
IINGCACISO ZEMPUMA NGOKWENZA LCD
- Isilinganiselo esilungileyo kunye nobuchule bokunikela abantu abamnyama abanzi.
- Ukuchaneka kombala nokuchaneka.
- Ukulandelwa kokunyusa okungcono (ukuhamba okufutshane okanye akukho ntshukumo ehambayo kwimifanekiso eshukumayo ngokukhawuleza ngenxa yokusetyenziswa kweTheknoloji ye- Sub Field Drive ).
- Ukujonga ukujonga ngakwesibini.
IINGCACISO ZEMPlasma vs LCD
- Iimvumi ze-Plasma azibonakali njengezoLCD ezininzi zeTV. Iimvumi zePlasma zenza ngcono ngendawo egqabileyo okanye ebumnyama.
- Umbala weskrini ubonakalisa ngakumbi kuninzi lwee-TV zeLCD. Eyona nto ingabonakaliyo kwi-screen ye-screen-screen ibonisa imithombo embane yokukhanya.
- Iimvumi ze-Plasma ziyakwazi ukutshisa imifanekiso emibi. Nangona kunjalo, le ngxaki iyancipha kakhulu kwiminyaka yamuva nje ngenxa yokubandakanywa kwe "pixel orbiting" kunye nobuchwepheshe obuhlobene.
- Iimvumi ze-Plasma zivelisa ukushisa okukhulu kwaye zisebenzisa amandla angaphezu kwee-TV ze-LCD, ngenxa yesidingo sokukhanya kwe-phosphors ukudala imifanekiso.
- Ayenzi kakuhle nakwiindawo eziphakamileyo.
- Ubungakanani obuncinane bokubonisa ubomi - oku kusetyenziswa ukuba kunjalo. I-Plasmas yasekuqaleni yayineeyure ezingama-30 000 okanye iiyure eziyi-8 zokujonga usuku lwe-9 leminyaka, elingaphantsi kweLCD. Nangona kunjalo, ixesha lokuphila kwesikrini liye laphucuka kwaye i-60,000-yeeyure yokuphila kweeyure sele iqhelekileyo, kunye nezinye iiseti zilinganiswe njengeziiyure ezingama-100 000, ngenxa yokuphucula iteknoloji.
UKUFUNA I-LCD kwi-TV yePlasma
- Akukho ukutshisa kweemifanekiso ezisemgangathweni.
- Ukushisa okushisayo.
- Akukho miba ephezulu yokusebenzisa imiba.
- Ukunyuka kokukhanya komfanekiso ngaphezu kwePlasma, eyenza i-LCD TV ibe bhetele ekubukeni kwiindawo ezikhanyayo.
- Iskrini somhlaba kwii-TV ezininzi ze-LCD akubonakali ngaphantsi kweeplasma ze-Plasma ze-TV, okwenza kube lula ukukhanya kwesikrini.
- Isisindo somzimba (xa kuthelekisa ubukhulu besikrini esifanayo) kunezi-Plasma.
- Ubomi obuninzi bokubonisa, kodwa i-gap iyancipha.
- Kwi-3D, nge-LCD unokhetho phakathi kweeyunithi ezisebenzisa i- Active Shutter ne-Glass Passive , kanti i-3D ye-Plasma TV isebenzisa kuphela inkqubo ye-Glass Shutter Glasses.
IINGCANDELO ZAMANQAKU E-LCD vs Plasma TV:
- Umlinganiselo ophantsi olwahlukileyo, kungekhona nje ukunika abantu abamnyama obunzulu, nangona ukunyuswa kokunyuka kokukhanya kwe-LED kuye kwanciphisa le galeko.
- Ukungahambi kakuhle kwindlela yokulandelela (izinto ezinokuhamba ngokukhawuleza zingabonakalisa izixhobo ze-artifacts) - Nangona kunjalo, oku kuphuculwe kunye nokuphunyezwa kwe- 120Hz kwesikrini sokuvuselela i-screen kunye ne-240Hz kwiinkqubo ezininzi ze-LCD, kodwa oko kungakhokelela kwi "Soap Opera Effect", apho imithombo yemithombo esekelwe kwifilimu ibonakala ngathi ifana nevidiyo.
- I-angle ebonakalayo ebonakalayo ecaleni kwinqanaba elingaphandle kwePlasma. Kwii-TV ze-LCD, kuqhelekile ukuqaphela ukugquma kombala okanye ukutshintsha kombala xa ususa isikhundla sakho sokubukela ngokubhekiselele kwicala lendawo yeziko.
- Nangona i-LCD yeTV ayiyi kuba nefuthe lokutshisa, kunokwenzeka ukuba iipikseli zomntu kwii-TV zeLCD zingatshiswa, kubangele amachashaza amancinci, abonakalayo, abamnyama okanye amhlophe abonakale kwisikrini. Iipekseli zomntu ngamnye azikwazi ukulungiswa, sonke isikrini sidinga ukutshintshwa kweso sihlandlo ukuba ukutshiswa kwepixel ngamnye kukucaphukisa.
- I-TV ye-LCD ivame kakhulu kunexabiso elilinganayo (kunye nobungakanani obufanayo) I-TV ye-Plasma, nangona oko akusekho nto, ngoku i-Plasma TV ziyekile.
4K Factor
Enye into eyongeziweyo ukubonisa ngokubhekiselele kumbambano phakathi kweLCD kunye ne-Plasma TV, kukuba xa ii- 4K Ultra HD TV zenziwe, abenzi beTV benza ukhetho ukwenza kuphela isisombululo se-4K kwii-TV ze-LCD, usebenzisa i-LED emva kokukhanyisa, kwaye, kwimeko ye-LG kunye no-Sony, iquka 4K kumabonwakude usebenzisa i-OLED iteknoloji .
Nangona kukhangeke ubuchwepheshe ukuvelisa kwaye kufake ukukwazi ukubonisa isisombululo se-4K kwi-TV ye-Plasma, kubiza kakhulu kunokwenza kwi-platform ye-LCD yeTV, kwaye kunye nokuthengisa kwee-TV zeplasma eziqhubekayo kwehla kwiminyaka, abenzi be-TV ye-Plasma wenza isigqibo seshishini sokungenisa i-TV ye-4K Ultra HD ePlasma kwi-market-based, eyayiyinye into ebangela ukuphela kwayo. I-4K Ultra HD ye-Plasma TV yodwa / eyenziweyo yenzelwe ukusetyenziswa kwesicelo soshishino.
Ngaphantsi
I-Plasma inendawo ephawulekayo kwimbali yeTV njengokuba iteknoloji eqalise ukuhamba kwiphaneli eplatiweyo, i-Hang-on-wall-wall-wall, kunye ne-video display device eyayithembisiwe ukususela ekuqaleni kwawo-1950. Ukuphuhliswa kwiminyaka engaphezu kwama-50 edlulileyo, ubuchule kunye nokuthandwa kwaso kubonakala kwiminyaka elishumi yokuqala yekhulu lama-21 kodwa ngoku sele kudlulele kwiGadi yeGadi ngenxa yentuthuko ye-LCD yeThekhnoloji ye-TV kunye nokufakwa kwee-TV ze-OLED, ezivalile ikhefu kunye nezinye iingenelo ezenziwa yiPlasma TV.
Ukujonga ngokubanzi ngakumbi kwi-LCD kunye ne-Plasma TV ukufanisa, kwakhona uyayifunda: Ngaba kufuneka ndizuze i-LCD okanye iPlasma TV? .
