Ukhetho lomsebenzisi: i-lcd

Iikhomputha ebomini bomhlali okhoyo ziyinxalenye yalo. Okwangoku namhlanje ukhetho olukhulu kunabo bonke ababonisi bekhomputha bafumene i-LCD-monitor. Ezi zinguqulelo zanamhlanje zinemivuzo emininzi ngaphezu kwabaphambili. Baye bahluke komnye nomnye.

Njengomthetho, abathengi abagqibayo ukwenza naluphi na ukuthenga, zama ukufumana inzuzo enkulu. Ngokubhekiselele kubahloli, nangu, okokuqala, abathengi abaninzi banomdla kwinqanaba elona lihle emehlweni, baninzi bayazi iingxaki ezinokubangelwa ukuchitha ixesha elininzi kwikompyutha. Ngokungathandabuzekiyo, abagadi be-LCD ba bhetele kuloluhlu kunezo zisekwe kwi- tube cathode-ray. Ngenxa yobuqhetseba besakhiwo, izikrini ze-crystal zamanzi aziyikudala nayiphi na imitha. Into kuphela echaphazela kakubi amehlo yomthengi yinkxalabo, ngamanye amaxesha ayidalwa xa elungisa ukukhanya. Kodwa esi siphumo singagwenywa ngokutshintsha le parameter kungekho kwisetyenziswe kweso, kodwa kwisetyenzisi sekhadi levidiyo. Kwi- CRT, i-flicker ixhomekeke kwisicatshulwa esifana nesilinganiselo sokuvuselela kwesikrini sokubeka esweni, kwaye unokuphephekisa imiphumo emibi kuphela xa uthengela ukhetho olubi. Ewe, namhlanje akuyona indlela engcono kakhulu yokuphuma. Kulula ukuthenga umboniso weLCD.

Okokuqala, xa ukhetha abahloli be-LCD, kufuneka uqaphele uhlobo lweematriki, apho kungabikho ixabiso elithembekileyo kuphela, kodwa nakweminye impawu, njengengalo yokubukela, ukungafani, ukuguqulelwa kombala, ukukhanya, ixesha lokuphendula, njl njl.

Mhlawumbi, ipharamitha kuphela apho abahloli be-LCD abangaphantsi kwee-CRTs ngumbono wokujonga. Oku bekubangelwa kwezinye iinkalo zobugcisa bokusetyenziswa. Phantse zonke iipaneli zeLCD, xa zijongwa kwinqanaba elikhulu, ziya kuphazamisa umfanekiso. Kodwa abakhiqizi basebenzela ngokukhawuleza ukuphelisa le mpazamo, kwaye kunokwenzeka ukuba kusasa kubakho iifayile ezinokuthi zingabonakali.

Enye yeeparitha ezibaluleke kakhulu kubonakaliso bekristal yamanzi yithuba lokuphendula kwezikristali. Umyinge ungaphantsi kwe-30 millisecond. Ixesha elide linokuba ngumphumo wokulibaziseka okubonakalayo ekutshintsheni ngokukhawuleza kwemifanekiso kunye neefowuni.

Abavelisi banamhlanje bahlula i-LCD-monitor ngokuxhomekeka kuhlobo lweematriki kwi-TN, i-IPS kunye ne-VA (ulungelelwano olufanayo). Udidi lokuqala lwabahloli lixabiso elihle kakhulu. Olu hlobo lwesimatri lubonakaliswa ngokusetyenziswa kwamandla aphantsi kunye nexesha lokuphendula kristall. Ukungalungi kukuguqulelwa kombala okungalungile, i-angle encane yokubukela kunye nokulinganisa okusemgangathweni. Phakathi kwezinye izinto, iindawo ezifile, njengomthetho, zihlala zivutha. Intsapho ye-IPS inokuqatshelwa ngombala obalaseleyo wokunikezela umbala, kunye ne-angle enkulu yokubukela. Iparameter yexesha lokuphendula liphezulu kunelohlobo lwangaphambili lwama matrices, kwaye uhlu lobuncinci lungaphantsi kwelo * VA. Inzuzo ebalulekileyo kukuba ngeephutha zepikelli, iipikseli ziba mnyama. Uhlobo lokugqibela lwe-matrix lunemibala enobumba obuhle kakhulu kunokohluko ophezulu. Zonke iinguqulelo zentsapho zenziwe ngabakhiqizi abahlukeneyo ukuphucula iimpawu, kodwa i-original ayifani kakhulu.

Ukukhetha uhlobo oluthile lwe-matrix, kufuneka lusekelwe ekusebenziseni kwalo. Ukuba kufuneka usebenze kakhulu kunye neeprogram zeeofisi, ngoko ke imigaqo yokukhetha eyona nto iya kuba yintengo kunye nokubonakala, ekubeni iimpawu ezisele kulo mcimbi aziyiyo inqununu. Kulo mzekelo, kufuneka uqaphele abagadi be-Acer (Acer P196HQVb, Acer P226HQbd, Acer A191HQLb) kunye ne-Samsung (Samsung S19A100N, Samsung B1930N, Samsung S20A300N). Ukusebenzisa umlenze kwi-shishini lokushicilela, apho umbala ngowona mzuzu obaluleke kakhulu, kucetyiswa ukuba ukhethe abagadi kunye ne -IPS matrix technology , umzekelo, (Asus VS209N, LG IPS225T, HP ZR2240w). Ikhompyutheni yasekhaya, eyona nto ifanelekileyo yinkqutyana kunye nohlobo lwe-matrix * VA (i-Samsung F2080, i-NEC EA191M), njengoko, ngokwenene, yinto yonke, ihlangabezana neemfuno, zombini izithandwa zemidlalo kunye nalabo abakhetha ukujonga iifoto kunye namavidiyo.
