Yintoni iliso?

Namhlanje phantse yonke intsapho inakho ikhompyutha. Kodwa bambalwa kakhulu abantu bayazi ukuba yintoni iliso, indlela esebenza ngayo kwaye yintoni ebandakanyiswe kwindlela yokusebenza kwayo?

I-iliso iyisisodwa esikhethekileyo esisetyenziswe ukubonisa umfanekiso. Kukho ezimbini iintlobo zezilindisi: i- monochrome kunye nombala. I-Monochrome, ngokulandelanayo, eyenzelwe ukuvelisa imifanekiso usebenzisa imibala emibini. Namhlanje, kukho iindlela ezimbini zokuhlola: iincwadi kunye nemifanekiso.

Siza kuhlalutya oko kweso sihlolo sokusebenza kwimo yombhalo. Le yesikrini ekwahlulelwe ngokwemimiselo. Njengomthetho, ulwahlula kwii-25 ezikhundla ezi-8. Ukuqhelana ngalunye yintsimi ethile, apho iimpawu ezithile ziboniswa. Inani elipheleleyo labalinganiswa lingama-256. Phakathi kwabo kukho iibhokisi ezinobunzima kunye neephantsi, amanqaku kunye neempawu zokubhala iimpawu zokubhala, iimpawu ezikhethekileyo kunye nezibonakaliso ze-pseudographic. Ukuba usebenzisa i-monitor ekwazi ukuvelisa umbala opheleleyo wemibala, ukuqhelana ngamnye kunokugqitywa ngombala okhethekileyo weetekisi kunye nomvelaphi.

Ngoku khawucinge ukuba yintoni iliso lokubonisa iirafu, imifanekiso ekhethekileyo kunye nezinye izinto. Okokuqala, siyaqaphela ukuba ngoncedo lwesilathisi sokubonisa imifanekiso ungabonisa imibhalo eyahlukeneyo kunye nefonti kunye nobukhulu obuhlukeneyo. Emva koko, olu hlobo lubonisa imifanekiso usebenzisa amaphuzu, ngaphezulu kwabo, ngcono kwaye kucace umfanekiso. Yonke into iyiphikseli. Ingaba nombala wayo, kwaye inani elipheleleyo lale ngongoma ngokubhekiselele kwaye liphezulu libizwa ngokuthi isisombululo seskrini somboniso.

Ngaphambi kokuba wenze ukuthenga, kufuneka uqonde ukuba yintoni umthamo we-matrix. Iyenziwa ngokusebenzisa ubuchwepheshe obuhlukeneyo, kwaye umgangatho wayo ubangelwa kubukhulu bamaphikseli (okusanhlamvu). Iipekseli ezingaphezulu, umgangatho ophezulu kakhulu wokubonisa umgangatho.

Ungaphuthelwa umbala we-gamut wesikrini. Inombolo yemibala ibonisa izinga lo mgangatho. Ngokutsho kwimiba yobugcisa nganye kwikhompyutheni nganye, kukho iindlela ezininzi zokubonisa imifanekiso: EGA, VGA, SVGA, LCD.

Ukujonga kwelinye lala ma modes, i-speed accelerator yekhompyutheni yakho kufuneka ifakwe imemori eyaneleyo. Imodi ye-SVGA ayixhaswa yizo zonke iinkqubo, kwaye abaqhubi abongezelelweyo bafakwe kwi-operation yayo evamile.

I-iliso iyisistim esinobukhulu obukhulu. Ukwabela i-intshi ezili-14, i-intshi ezingama-17, 19 ne-21 intshi. Iintshi ubude bekrini ediagonal.

Njengoko sele kukhankanywe, enye inkcazelo ebalulekileyo xa ukhetha i-monitor iyinani lesantya leskrini (pixel). Okwangoku, ubukhulu bepikelel ubukhulu buyi-0.26-0.28 mm. Ukuba iliso likhethwe ngamanani amakhulu, ngoko ke kuyimfuneko ukusebenzisa iiglasi ezikhethekileyo ezingabonakaliyo, ekubeni loo maphupha enempembelelo embi emehlweni.

Namhlanje, phantse akukho ziqapheli eziveliswa ngesiseko se-kinescope, ii-LCD okanye iplasma zinyuka ngokunyuka. Ezi zibuchwephesha obudume kakhulu, zixubene ngakumbi, abahloli abanjalo banokuphoswa eludongeni. Abakhiqizi abathandwa kakhulu yi-LG, i-ViewSonic, i-Samsung, i-Sony ne-Panasonic.

Siye sahlaziya ukuba yintoni iliso kunye neyiphi iiparitha zayo eziphambili. Xa uthengi, jonga ukufumaneka kwamacandelo kunye namaxwebhu anxulumene.
