Iithelevishini zepaneli zepaneli ngoku ziqhelekileyo kwiindawo zokugcina izitrato nakwizindlu zabathengi. Iifowuni zepaneli zepaneli zeplani, kunye nokuphuculwa kwazo kwamanani kunye nokuphuculwa komsebenzi kuya kuba yinto enqweneleka kakhulu kwi-CRT. Nangona kunjalo, ngaphambi kokuba ugxume kwi-intanethi "inkontileka enkulu ye-ad" kwi- LCD yepaneli yepaneli yepaneli , kukho ezinye iingcebiso ezifunekayo zokuqwalasela ukuba ukhangele ntoni xa uthengisa i- LCD TV .
Fumana indawo yokubeka i-LCD yakho yeTV
Ekubeni i-LCD yeTV iyancinci, ingaba udonga okanye itafile ifakwe. Ukuze udonga lufakwe kwi-LCD TV, gwema ukubeka phezu komlilo osebenzayo. Ubushushu obuvela kwindawo yomlilo lunokuchaphazela ukusebenza nokuhlala ixesha elide. Ukuba usebenzisa isamba setafile esinikeziwe, thabatha umlinganiselo kumthengisi kunye nawe ukuze uqinisekise ukuba ububanzi bonke besethi buya kufumana kwindawo yakho. Qinisekisa ukuba ushiye enye inye intshi ezimbini kwicala ngalinye, phezulu, nangemuva, ukwenzela ukungena umoya kunye nokufikelela kokuxhumeka.

Solution Pixel
I-LCD ipaneli yepaneli yeplati eneenombolo ezichanekileyo zeepikseli kwi-screen surface. Isisitshixo kukufumana inani eliphezulu lepikseli yokuzalwa njengokuba kunokwenzeka. Uninzi lwee-TV ze-LCD ezingama-intshi ezingama-23 kwaye phezulu kwisesayizi yeskrini zinika ubuncinane i-1280x720 (720p) okanye i-1366x768 (768p) isisombululo se-pixel yangasese. Le yile ncinane yepikseli ibalwa ukuba umele ukhangele kwi-LCD ithelevishini.
Ukongeza, i- LCD yeTV ephezulu (i-inches 40-inches and larger) ngoku i-1920x1080 (1080p) okanye i-3840x2160 (4K) isisombululo se-pixel yangasese, enokubaluleke nakakhulu, ngakumbi ukuba unayo, okanye uceba ukuthenga iBlu- I-Disc Disc okanye i-Ultra HD Disc player.
Ukunyuka
Ukunyuka yinkqubo apho umbonisi wevidiyo womabonwakude uza kufana nesisombululo sesignali engenayo kwisisombululo sakhe sepikseli. Oku kuthetha ukuba izisombululo ezincinci ziza kuphakanyiswa, kodwa umprosesa uya kugxotha amanqaku angaphezulu okuza kusombulula ukwenzela ukuba angaboniswa kwi-TVs.
Ukunyuka okungekho nto kunokubangela izixhobo zokusebenza, ezifana neengqungquthela ezigqithisiweyo kunye neenkcukacha ezingahambelaniyo. Kufuneka kwakhona kuqaphele ukuba iziphumo zixhomekeke kumgangatho wesignali engenayo.
Isikhathi sokuphendula
Ikhono le-LCD TV ukubonisa izinto ezihamba phambili ngokukhawuleza, ngaphambili, yayinobuthathaka bubuchwepheshe beLCD. Nangona kunjalo, oku kuphuculwe ngokuphawulekayo. Oku akuthethi ukuba zonke ii-TV ze-LCD zenziwe zilinganayo kule ndawo.
Hlola iinkcukacha ze-Motion Response Time (ms = millisecond). I-TV efanelekileyo ye-LCD ngoku kufuneka ibe nexesha lempendulo ye-8ms okanye i-4ms, kunye ne-4ms i-optimum, ngokukodwa xa ubona iindidi zezemidlalo okanye izenzo zefilimu. Qaphela ii-LCD zeTV ezingabhalwanga ixesha lokuphendula.
Enye into engabangela inkxaso kwixesha lokuphendula i-Screen Refresh Rate.
Uluhlu lwemiqathango
Umlinganiselo wokungafani, okanye iqondo lokutshintsha kweendawo ezimhlophe kunye ezimnyama zomfanekiso, yinto ebalulekileyo ekufuneka uyiqaphele. Ukuba i-LCD TV inomlinganiselo ophantsi wokumelana, imifanekiso emnyama iya kubonakala ibe yidaka kunye ne-grey, ngelixa imifanekiso ekhanyayo iya kubonakala ihlanjwe.
Kwakhona, musa ukukhohliswa yi- Contrast Ratio marketing hype. Xa uhlola iinombolo zomlinganiselo wohlobo, jonga ukuhlukana koMdabu, iStatic, okanye i-ANSI, kungekhona ukuxhatshazwa kweDynamic okanye okupheleleyo / okupheleleyo. U-ANSI umehluko umele umehluko phakathi komnyama nomhlophe xa bobabini besesikrinini ngexesha elinye. Ukuqhathaniswa kweDynamic okanye okupheleleyo / OKUQHELEKILEYO kuphela amanyathelo omnyama ngokwawo kunye nomhlophe ngokwawo.

Isiphumo sokuKhanya kunye nokuKhanya
Ngaphandle kokuveliswa kokukhanya okwaneleyo (kulinganiswa kwiiNits), ukukhanyiswa komfanekiso wakho weTV kuya kubonakala kukudaka kwaye kuyithambile, nakwikamelo elimnyama. Ukongezelela, ukujonga umgama , ubungakanani bekrini, kunye nokukhanya kwendawo yokukhanya kuya kuthintela ukuba kukhanya kangakanani i-TV yakho kufuneka ikhuphe ukuze ibonelele ngomfanekiso oqinileyo.
Ukujonga i-Angle
Qinisekisa ukuba ungayijonga umfanekiso kwi-TV yeLCD ukusuka kumacala kunye nakwindawo yokubukela kuqala. Ii-TV ze-LCD ziba neekona elifanelekileyo lokujonga ihlangothi-nhlangothi, kunye neeninzi zihamba ngokubanzi njengama-Degrees angama-160, okanye malunga ne-80 degrees ukusuka kwindawo yokujonga indawo.
Ukuba ufumanisa ukuba umfanekiso uqala ukutshabalalisa okanye ungabonakaliyo kwii-degrees ezingama-45 ukusuka kwicala lendawo yokubukela indawo, mhlawumbi kungabi lukhetho olufanelekileyo apho unayo iqela elikhulu lababukeli behleli kwiindawo ezahlukeneyo kwigumbi.
Iingxowa kunye neConection Conection
Phantse yonke i-TV ye-LCD manje sele yakha zombini i-NTSC kunye ne- ATSC . I-tuner ye-ATSC iyadingeka ukuba ifumane iimpawu zokusasazwa nge-TV emva kwe-Juni 12, 2009. Kwakhona, ezinye ii-TV ze-LCD zinezinto ezibhekiswa kuzo njenge-tuner ye-QAM. I-tuner ye-QAM yinto efunekayo ukufumana inkqubo engabonakaliyo yeComputer-Cable ngaphandle kwebhokisi yekhebula (oku kubonakala kunqabile njengeenkqubo zekhebula zichonga iziteshi ezininzi.
Ukongeza, i-LCD TV oyithengayo kufuneka ibe neyodwa ingeniso ye-HDMI yokuxhamla imithombo ye-HD , njenge-HD-cable okanye ibhokisi le-satellite, i- Upscaling DVD okanye i- Blu-ray Disc player .
