Ubugcisa ezizezinye: LCD-ukubonisa, okanye "plasma"?

Namhlanje akukho kuwuthandabuza umba wokuba le ngcono - CRT monitor okanye LCD-uboniso. Kuba umsebenzisi avareji asithandabuzi. kubuxhakaxhaka bokuvelisa LCD esoloko kuphuculwe yaye kuvula ezintle ezintsha entsimini. Liliphi ithemba ukuba kunokwenzeka, xa kuphuhliswa ngakumbi? Ingaba LCD ukukhuphisana ngempumelelo engenye technologies kanjani?

isifinyezo awuphathe LCD (Ulwelo Crystal Display) yi crystal ezaziwayo-kakuhle wamanzi umboniso. Owasungula le ubuchwepheshe ixesha elide, kodwa ngenxa yobunzima kwi imveliso mveliso iye ayifumanekanga isicelo ngokubanzi. izikrini ezincinane ezinjalo ziikristale zinokubonakala kule wotshi yedijithali ngelo xesha. Baba emnyama namhlophe kunye baba elifutshane elide. Ngelo xesha kukho ngakumbi kwaye ezikumgangatho ophezulu imifuziselo kweetyhubhu cathode ray (CRTs), apho ngcembe yoyiswa phantse imarike yonke.

Uphuhliso technology LCD kwenzeka phantse iminyaka engama-30 kwaye ikhokelele iziphumo kakhulu. Ukuza kuthi ga ngoku, LCD-uboniso indawo phantse ngokupheleleyo okhuphisana yayo elektroniki eligcinele ezishelifini. It has yokusebenza egqwesileyo icompetition kunye nezixhobo ezizezinye.

Modern LCD-uboniso kwi parameters kude owayephambi yayo black and white:

1. Waqalisa ukukhonza ixesha elide.
2. Ngokuphindaphindiweyo ngcono isisombululo sekhusi kunye nobukhulu.
3. Ukuqaqamba ayikho ngaphantsi i esweni CRT.
4. umahluko Good (250: 1).
5. Zintle ukubukela angle (degrees 120).
6. ubukhulu ezincinane kunye nobunzima ukukhanya.

Ukuza kuthi ga ngoku, LCD-libonisiweyo nomtsalane ngakumbi kumthengi ngaphezu kokuba esweni CRT. Enye ingaba kuphela plasma screen, kodwa ukuphunyezwa layo, nto leyo eya kwanelisa iimfuno loluhlu olubanzi abasebenzisi, ziya kubakho ixesha elide. Ithekhinoloji imveliso yawo imali eninzi kakhulu yaye nexesha elide, it has a ukusetyenziswa eliphezulu amandla, kunye nombala iingxaki yokuzala ngayo iyafana naleyo nezinye okhuphisana nawo. Ukongeza "plasma" kunzima kakhulu ukufikelela kwisisombululo eliphezulu. main inzuzo yaso ebumhlotsheni omkhulu umahluko. Ngesi parameter oko ngaphambi kwezinye iintlobo ngamagosa okubeka esweni iimviwo. Kodwa le imilinganiso LCD-imiboniso ziinkokheli, ukuba indawo yaye "plasma", kunye CRT kakhulu ngakumbi. Kufuneka kuqatshelwe nokhuseleko lwabo ngokupheleleyo impilo yabantu. Ayenze imitha eziyingozi kunye namasimi kagesi.

Kodwa yonke imveliso iye kuneengxaki zawo, ukusuka apho awukwazi balahle. Phambi kokuba uthenge i LCD-umboniso, qaphela ubukho pixels "eyaphukileyo". Kukholelwa ukuba enye kwikhusi, ungabi ngaphezu kwe-ezintathu kufuneka. Ukwahlula enye ilula - pixels zisoloko akhanyiswe umbala omnye kuphela. Vavanya ikhusi, ukutshintsha umfanekiso uhlobo olufanayo, uze ukhethe umgangatho uphezulu.

Technology liye amathuba umdla di- iiplastiki (Light Emission Plastics). Ngoko ivela, kwaye inkampani Cambridge Bonisa Technology abaye baphumelela inkqubela enkulu kule nkalo. Le likhanya ezi imikhusane sikhula yaye yayokufika kwizinga lomyinge we-LED olukhoyo namhlanje.
