Alternative ubuchwepheshe: LCD-display, noma "plasma"?

Namuhla, akukho nokuncane ukungabaza ukuthi ngcono - CRT qapha noma LCD-isibonisi. Ukuze umsebenzisi isilinganiso ukukhetha isobala. ubuchwepheshe ukukhiqizwa LCD njalo ngcono futhi okuvulela khathizwe amasha emkhakheni. Yeka amathemba zingenzeka, lapho athuthukiswe? Ingabe LCD ukuncintisana ngempumelelo ubuchwepheshe okunye ongakwenza?

isifinyezo Sheer LCD (Liquid Crystal Display) kuyinto owaziwa okucaciswe luketshezi. Yasungulwa lobu buchwepheshe bekulokhu impela isikhathi eside, kodwa ngenxa ukuthi yibuphi ubunzima ukukhiqizwa yezimboni uye ayitholakalanga isicelo ebanzi. izikrini ezincane zinhlayiya enjalo kungabonwa on iwashi digital ngaleso sikhathi. Kwakumelwe omnyama nomhlophe kanye saba sifushane. Ngesikhathi esifanayo kukhona onobuhle ngaphezulu futhi eliphezulu of cathode ray amashubhu (CRTs), okuyinto kancane kancane yanqoba bacishe bayifunda yonke emakethe.

ukuthuthukiswa LCD ubuchwepheshe kwenzeke iminyaka ecishe ibe ngu-30 futhi kuye kwaholela ngemiphumela emangazayo. Kuze kube manje, LCD-isibonisi avuselelwa cishe ngokuphelele esincintisana zalo electronic kusuka esitolo emashalofini. It has ukusebenza kakhulu futhi kuphazanyiswa amadivayisi enye.

Modern LCD-iboniswe nemingcele zikude esasisandulele ngombala omnyama nomhlophe:

1. Waqala ukukhonza isikhathi eside.
2. Ngokuphindaphindiwe ngcono nesinqumo kanye nosayizi.
3. Ukugqama akuyona ngingelutho uma ngiziqhathanisa qapha CRT.
4. Ngokuphambene Good (250: 1).
5. engela Excellent wokubuka (degrees 120).
6. Usayizi ezincane nesisindo ukukhanya.

Kuze kube manje, LCD-isibonisi sikhange ngokwengeziwe kubantu ezisebenza umthengi ngaphandle qapha CRT. Enye kungaba isikrini plasma, kodwa ukuqaliswa salo esisebenzayo okuzokwenza ukwanelisa izidingo ezahlukene abasebenzisi, kuyoba okwesikhathi eside. Ubuchwepheshe ukukhiqizwa yayo ibiza kakhulu isikhathi, it has a high power ukusetshenziswa, futhi umbala izinkinga ukukhiqizwa kabusha ke kuyafana eyomunye izimbangi. Ngaphezu "plasma" kunzima kakhulu ukufeza isinqumo eliphezulu. Inzuzo yayo eyinhloko ukukhanya okuphezulu nekuphikisana. Ngalokhu ipharamitha kuba ngaphambi ezinye izinhlobo nabaqaphi. Kodwa izilinganiso LCD-ekhombisa kukhona abaholi, zingabantu icwecwe futhi "plasma", futhi CRT okuningi. Kufanele kuqashelwe nokuphepha kwabo okuphelele nempilo yabantu. Ayenze emisebeni eyingozi namasimu kagesi.

Kodwa kuzo zonke ukukhiqizwa has nezihibe, okuyindawo awukwazi ukuqeda. Ngaphambi uthenga LCD-display, uqaphele khona Amaphikseli "ile". Kukholakala ukuthi screen eyodwa, akufanele kube khona ezingaphezu kwezintathu. Ukuhlukanisa kubo kusukela lonke ulula - Amaphikseli njalo ovuthayo ngemibala eyodwa kuphela. Hlola isikrini, ukushintsha isithombe yohlobo olufanayo, bese ukhetha izinga eliphakeme kakhulu.

Ubuchwepheshe has amathemba ezithakazelisayo likhipha Plastics (Light Emission Plastics). Kuyinto elokhu ivela, futhi inkampani Cambridge Khombisa Technology baye baphumelela inqubekela phambili kulokhu. Luminosity lezi izikrini sikhula kahle futhi kufinyelelwe ezingeni of LED yesimanje namuhla.
