Umthengi Ukukhetha: LCD Abaqaphi

Ezamakhompiyutha emphilweni kule ndoda emgwaqweni ziyingxenye ebalulekile yalo. Kuze kube manje, preference enkulu wathola LCD-ngabaqaphi phakathi kwekhompyutha nabaqaphi. Lezi ukulungiswa yesimanje kunezimo eziningi phezu ababengaphambi zabo. Futhi ihluke nomunye.

Ngokuvamile, abathengi abakhetha ukwenza noma yiluphi uhlobo lokuthenga, zama ukuthola esiphezulu inzuzo ngangokunokwenzeka. Ngokuqondene qapha, kukhona, okokuqala kunakho konke, amakhasimende abaningi banesithakazelo, okuyinto qapha kungcono ngoba amehlo, njengoba abaningi bayawazi izinkinga kungenzeka kubangelwa ngokuchitha isikhathi esengeziwe ngesikhathi ikhompyutha. Ngokungangabazeki, kulesi sigaba LCD-ngabaqaphi zingcono kakhulu kunalezo at ngesisekelo ngubani ngamapayipi cathode ray. Ngenxa izici kwesakhiwo, LCD izikrini musa ukuveza noma yiphi kwekhabhoni. Into kuphela ukuthi kungathinta iso umthengi, ke siyafiliza, ngezinye izikhathi wadala lapho ukulungisa ukugqama. Kodwa lo mphumela kungagwenywa ngokushintsha lokhu kulungiselelwa alikho izilungiselelo qapha, nezilungiselelo isiqophi ikhadi. Ngo CRT uqaphe kulokolokoza incike izici ezifana izinga refresh kwesikrini we qapha, futhi ugweme imithelela emibi kungaba esimweni ukuthenga inketho ezibizayo. Yiqiniso, namuhla leli akulona ikhambi best. Vele ukuthenga okucaciswe luketshezi.

Okokuqala, nokukhetha-LCD-Abaqaphi, kufanele sinake nohlobo-matrix, esithinta hhayi kuphela intengo kodwa futhi nezinye izici ezifana engela yokubuka, nika umehluko, umbala imifanekiso, ukukhanya, Ukusabela isikhathi, kanjalonjalo.

Mhlawumbe, wukuphela ngawo CRT phansi kunabaphostoli LCD-ngabaqaphi uyabuka engela. Lokhu kubangelwa ukuqaliswa izici ezithile steel ubuchwepheshe. Cishe zonke iphaneli LCD uma ubheka kubo engela ezinkulu phendulela isithombe. Kodwa abakhiqizi ngenkuthalo ukusebenza ukuze kuxazululwe le ukuntula futhi kungenzeka ukuthi maduze ngeke esaba khona onobuhle cishe lengenamaphutsa.

Omunye nemingcele ebaluleke kakhulu ngoba liquid crystal display Samukelwa nesikhathi crystal. Izinga evamile engaphansi kuka 30 millisecond. Isikhathi esiningi ingase ibe umphumela ukuvela ukubambezeleka abalulekile ngendlela alternation okusheshayo kwezithombe kanye ozimele.

abakhiqizi Modern uhlukanise LCD-ekhombisa ngokuvumelana matrix uhlobo TN, IPS futhi * VA (Vertical Ukuhambisana). Isigaba sokuqala ngabaqaphi inenani ezimnandi kakhulu. Lolu hlobo lwe-matrices libhekene iphansana energy ukusetshenziswa kanye Ukusabela nesikhathi zinhlayiya. Okumbi zihlanganisa okungaqondile color yokuhumusha, engela encane wokubuka kanye Ngokuphambene ngokwanele ongaphakeme. Phakathi kwezinye izinto, izindawo ezingabonakali ezibukweni, njengoba umthetho, njalo evutha. Ngezinye IPS umndeni kungaba inkomba enhle ukuhlonza umbala kakhulu, kanye engela kahle esikhulu. Sepharamitha Ukusabela isikhathi sibe sikhulu kunesihlalo izinhlobo yangaphambilini ye-matrices, kanye umehluko esingaphansi * VA. A inzuzo enkulu wukuthi pixels ayoba mnyama ne-pixel elingu amaphutha. Uhlobo yokugcina-matrix ine omuhle kakhulu umbala ukukhiqizwa kabusha ngesikhathi Ngokuphambene kahle eliphezulu. Zonke izinguqulo alo mkhaya zenzelwe abakhiqizi ezahlukene ukwandisa izimfanelo ukusebenza original kodwa akuzona ovelele kakhulu.

Ukukhetha elilodwa noma kwenye uhlobo-matrix, kufanele esekelwe ukusetshenziswa kwaso phambili. Uma une ukusebenza ikakhulukazi software ehhovisi, main nenqubo yokukhetha kuyoba intengo kanye nokubukeka, nezinye izici kulesi simo kungukuthi olunezimiso. Kulokhu, kufanele sinake ukuqapha amafemu Acer (Acer P196HQVb, Acer P226HQbd, Acer A191HQLb) ne-Samsung (Samsung S19A100N, Samsung B1930N, Samsung S20A300N). Ukusebenzisa qapha embonini sokushicilela, lapho iphuzu elibalulekile kuyinto umbala yokuhumusha, kutuswa ukuba akhethe ngabaqaphi ngobuchwepheshe be-matrix IPS, isibonelo, (Asus VS209N, LG IPS225T, HP ZR2240w). Ukuze ikhompyutha ofanele kakhulu ekhaya uzoqapha-matrix uhlobo * VA (Samsung F2080, NEC EA191M), ngoba, eqinisweni, jikelele ukuthi iyahlangabezana nezidingo kokubili wabadlali kanye labo abakhetha ukubuka izithombe namavidiyo.
