Incazelo ye-LCD nokuthi ihluke kanjani kunezikrini ze-LED
I-LCD efingqiwe, ukuboniswa kwe-crystal display yikhiqiza elincane, elincane elibonisa indawo ye- CRT . I-LCD inikeza ikhwalithi yesithombe engcono nokusekela izinqumo ezinkulu.
Ngokuvamile, i-LCD ibhekisela kuhlobo lokuqapha olusebenzisa ubuchwepheshe be-LCD, kodwa futhi ukubonisa isikrini esicwebekile njengalezo ze-laptops, izibalo, amakhamera wedijithali, amawashi wedijithali, namanye amadivaysi afanayo.
Qaphela: Kukhona nomyalo we-FTP osebenzisa izinhlamvu "I-LCD." Uma ngabe yilokho okulandelayo, ungafunda kabanzi mayelana nalo lapha, kodwa ayihlangene namakhompiyutha noma ukubukwa kwe-TV.
Izikrini ze-LCD Zisebenza kanjani?
Njengoba "ukukhonjiswa kwe-crystal liquid" kungabonisa, izikrini ze-LCD zisebenzisa amakristalu wamanzi ukushintsha amaphikseli futhi avule ukuveza umbala othize. Ama-crystals e-liquid afana nengxube phakathi kokuqinile nokuketshezi, lapho kukhona khona amandla kagesi angasetshenziswa ukuze ashintshe isimo sakhe ukuze kube khona ukusabela okuthile okwenzekayo.
Lezi zinhlaka zamakhemikhali zingacatshangwa njenge-window shutter. Uma i-shutter ivulekile, ukukhanya kungadlula kalula egumbini. Ngezikrini ze-LCD, lapho amakristalu ehambisana ngendlela ekhethekile, abasavumeli lokho kukhanya kudlule.
Ingemuva kwesikrini se-LCD esiphethe ukukhanya ekukhanyeni kwesikrini. Ngaphambi kokukhanya yisikrini esakhiwa ngamaphikseli anemibala ebomvu, eluhlaza okwesibhakabhaka, noma eluhlaza. Amakristali amanzi akhiphe ukuvula noma ukuvala isikrini nge-elekthronikhi ukuze aveze umbala othize noma agcine leyo pixel emnyama.
Lokhu kusho ukuthi izikrini ze-LCD zisebenza ngokuvimbela ukukhanya okuvela ngemuva kwesikrini esikhundleni sokudala ukukhanya ngokwakho njengokuthi izikrini ze-CRT zisebenza kanjani. Lokhu kuvumela abahloli be-LCD nama-TV ukusebenzisa amandla angaphansi kakhulu kune-CRT.
I-LCD vs LED: Iyiphi i-Difference?
I-LED imele ukukhanya okukhipha ukukhanya . Nakuba unegama elihlukile kune- liquid crystal displa y, akuyona into ehluke ngokuphelele, kodwa ngempela nje uhlobo oluhlukile lwe -screen LCD.
Umehluko omkhulu phakathi kwe-LCD ne-LED izikrini ukuthi zihlinzeka kanjani ukubuyisela emuva. Ukukhanyisa kubhekisela endleleni isikrini esikhanyisa ngayo noma esivaliwe, into ebalulekile ekuhlinzekeni isithombe esihle, ikakhulukazi phakathi kwezinxenye ezimnyama zemibukiso yeskrini.
Isikrini esibucayi se-LCD sisebenzisa isibani se-cathode fluorescent (CCFL) ngezinhloso zokubuyiselwa emuva, kuyilapho izikrini ze-LED zisebenzisa i-diode ebonisa ukuphumelela nokukhanya okuncane (LED). Umehluko kokubili ukuthi i-CCFL-ibuyele emuva i-LCD ayikwazi ngaso sonke isikhathi ukuvimba yonke imibala emnyama, lapho kwenzeka into efana nomnyama emhlophe kumabhayisikobho ingase ingabonakali emnyama ngakho konke, kuyilapho i-LCD ye-LED-backlit ingakwazi ukubona ubumnyama obuhlukile kakhulu.
Uma unzima kanzima ukuqonda lokhu, cabanga nje ngesimo se-movie somnyama njengesibonelo. Esikhathini sendawo yinkimbinkimbi emnyama, ebomvu elinomnyango ovaliwe ovumela ukukhanya okuthile ngokusebenzisa ukuqhuma okuphansi. Isikrini se-LCD esinokukhanyisa kwe-LED singasikhipha kangcono kunezikrini zokubuyiselwa kwe-CCFL ngoba abakuqala bangakwazi ukuvula umbala nje kwesigaba esiseduze nomnyango, okuvumela konke okunye kwesikrini ukuba kuhlala bube mnyama ngempela.
Qaphela: Akuwona wonke ukubonisa kwe-LED okwazi ukunciphisa isikrini endaweni yangakini njengoba ufunda nje. Ngokuvamile kuvamise ukugcwele kwe-TV (okuphikisanayo okukhanyayo) okusekela ukucwiliswa kwendawo.
Imininingwane eyengeziwe nge-LCD
Kubalulekile ukunakekelwa ngokukhethekile lapho uhlanza izikrini ze-LCD, kungakhathaliseki ukuthi zingama-TV, ama-smartphones, abaqaphi bamakhompiyutha, njll. Bheka Indlela Yokuhlanza i-Flat Screen TV noma i-Computer Monitor ngemininingwane.
Ngokungafani nabahloli be-CRT nama-TV, izikrini ze-LCD azikho izinga lokuvuselela . Kungase kudingeke ushintshe ukulungiswa kwesilinganiso sokuvuselela kwesikrini kwesikrini sakho se-CRT uma ubunzima bamehlo kuyinkinga, kodwa akudingeki kuzikrini ze-LCD ezintsha.
Iningi labahloli bekhompyutha LCD banokuxhumana kwezingcingo ze-HDMI ne- DVI . Abanye basasekela izintambo ze- VGA kodwa lokho akuvamile kakhulu. Uma ikhadi lekhompyutha yakho kuphela lisekela ukuxhuma kwe-VGA endala, qiniseka ukuthi kabili hlola ukuthi umlingo we-LCD unokuxhumeka kuwo. Kungase kudingeke uthenge i-VGA ku-HDMI noma i-VGA ku-adapter ye-DVI ukuze zombili iziphetho zingasetshenziswa kudivayisi ngayinye.
Uma kungekho lutho olubonakalayo kukhompyutheni yakho yekhompyutheni, ungakwazi ukuhamba ngezinyathelo ekuhloleni kwethu Indlela Yokuhlola I-Computer Monitor Engayisebenzisi Umhlahlandlela Wokuxazulula Izinkinga ukuze uthole ukuthi kungani.
