Inkcazo yeLCD kunye nendlela ehluke ngayo kunezikrini ze-LED
I-LCD echanekileyo, ukubonakalisa i-crystal display isisitrato esicacileyo, esincinci sokubonisa isibonakaliso sokutshintsha kwe- CRT . I-LCD inikezela ngobunjani bomgangatho wesithombe kunye nenkxaso yezigqibo ezinkulu.
Ngokuqhelekileyo, i-LCD ibhekisela kwindlela yokujonga i-LCD iteknoloji, kodwa i-screen display efana neye-laptops, i-calculators, iikhamera zedijithali, iwashi zedijithali kunye namanye amacebo afanayo.
Qaphela: Kukhona umyalelo weFTP osebenzisa iileta "LCD." Ukuba ngaba nguwe olandelayo, unokufunda ngaphezulu malunga nalo apha, kodwa akanalo nantoni na iikhomputha okanye i-TV.
I-LCD Skreens Work?
Njengoko "ukubonakaliswa kwekristal ebonakalayo" kuya kubonisa, izikrini ze-LCD zisebenzisa iikristali zamanzi ukuguqula iipikseli kunye nokucima ukubonisa umbala othile. Amakristali e-liquid afana nomxube phakathi kokuqinileyo kunye nombane, apho kungasetyenziswa khona umbane wamandla ukuguqula imeko yabo ukuze kubekho ukuphendula okuthile.
Ezi kristali zamanzi zicingelwa njengefestile yefestile. Xa i-shutter ivulekile, ukukhanya kulula ukudlula ngaphakathi kwigumbi. Ngezikrini ze-LCD, xa i-crystals ihambelana ngendlela ekhethekileyo, ayisayi kuvumela ukuba kukhanya.
Ingemuva kwesikrini seLCD esinoxanduva lokukhanya ekukhanyeni kwesikrini. Ngaphambi kokukhanya kwisikrini esenziwe ngamaphikseli anemibala ebomvu, eluhlaza okwesibhakabhaka, okanye eluhlaza. Amakristal ekhefu ayenoxanduva lokutshintshela ngekhompyutha okanye kucima ukuze kuvezwe umbala othile okanye ugcine loo pixel emnyama.
Oku kuthetha ukuba izikrini ze-LCD zisebenza ngokukhusela ukukhanya okuvela kumva kwesikrini endaweni yokudala ukukhanya njengendlela i-CRT izikrini zokusebenza ngayo. Oku kuvumela i-LCD ukujonga kunye ne-TV ukuba basebenzise amandla angaphantsi kuneCRT.
I-LCD vs LED: Yiyiphi i & # 39; s yohluko?
I-LED imele i- diode ekhanyayo . Nangona inegama elihlukile kune -crystal displa y, akuyona into ehluke ngokupheleleyo, kodwa ngokwenene nje uhlobo oluhlukile lwe -LCD kwesikrini.
Umehluko omkhulu phakathi kwe-LCD kunye ne-LED izikrini yindlela ababonelela ngayo ngokukhanyisa. Ukubuyiselwa kwesikrini kubhekisela kwindlela isibuko esikhanyisa ngayo okanye sivaliwe, into ebalulekileyo ekuboneleleni umfanekiso omkhulu, ngokukodwa phakathi kwimibala emnyama neyenemibala yeskrini.
Ikhutshana le-LCD eliqhelekileyo isebenzisa isibane se-cathode fluorescent isibane (CCFL) ngenjongo yokukhanyisa, ngelixa izikrini ze-LED zisebenzisa i-diode ezikhanyayo ezincinci kunye nezincinci (ii-LED). Ukwahlula kwezo zombini kukuba iCCFL-ibuyisela i-LCD ayinakuze ikhusele yonke imibala emnyama, apho imeko into enjengomnyama emhlophe kumabhayisikobho ingabonakali yinto emnyama emva kwayo yonke, ngelixa i-LED-backlit LCD ingayifumana ubumnyama ngokuchasene kakhulu.
Ukuba unzima ukuqonda oku, khawuqwalasele umboniso omnyama we-movie njengomzekelo. Kwimeko yindawo ebumnyama, ebumnyama enomnyango ovaliweyo ovumela ukukhanya okuthile ekugqibeleni. Isikrini se-LCD esinokukhanyisa i-LED sinokukutshintsha kangcono kunezikrini zokubuyiselwa kweCCFL ngenxa yokuba umntu ongaphambili angavula umbala wecandelo nje lomnyango, ukuvumela yonke indawo yesikrini ukuba ihlale imnyama ngokwenene.
Qaphela: Akukho bonkcoko nganye ye-LED inokukwazi ukunciphisa isikrini ngaphakathi kwendawo efana nokufunda nje. Ngokuqhelekileyo ithelevishini ye-TV epheleleyo (ngokubhekiselele kwimibala ebanzi) exhasa ukutshabalalisa kwendawo.
Ulwazi olongezelelweyo kwiLCD
Kubalulekile ukunyamekela xa uhlambulula izikrini ze-LCD, nokuba ziiTV, ii-smartphones, izilwanyana zekhompyutheni, njl. Bona indlela yokucoca i-Flat Screen ye-TV okanye i-Computer Monitor malunga neenkcukacha.
Ngokungafani nabagadi be-CRT kunye namaTV, ii-LCD izikrini azikho izinga lokuvuselela . Ungadinga ukutshintsha i-setting ye-rate yokuvuselela isantya kwisikrini sakho se-CRT ukuba ubunzima bamehlo bunengxaki, kodwa akudingeki kwii-LCD ezintsha zesikrini.
Uninzi lwabalindi bekhompyutha LCD banxibelelwano lwe-HDMI kunye neDVI . Abanye baxhasa izixhobo ze- VGA kodwa oko kudla kakhulu. Ukuba ikhodi yevidiyo yekhomputha yakho isekela uxhulumaniso lwe-VGA oludala, qiniseka ukuba uphinde ukhangele ukuba i-monitor ye-LCD inxulumene nayo. Ungadinga ukuthenga i-VGA kwi-HDMI okanye iVGA kwi-adapter ye-DVI ukuze iziphelo zombini zisetyenziswe kwisixhobo ngasinye.
Ukuba akukho nto ibonisa ukujonga kwikhompyutheni yakho, ungakwazi ukuhamba ngokusebenzisa amanyathelo kwindlela yokuvavanya i-Computer Monitor engayisebenzisi inkcazo yokujongana neengxaki zokufumanisa ukuba kutheni.
