Maxay yihiin noocyada kala duwan ee ilaaliyeyaal?

La soco - qayb muhiim ah oo nidaam computer kasta. Waa qalab by taas oo computer ku sheegayaa qof natiijada shuqulkiisa. Haddii la isticmaalayo mouse iyo keyboard, user wuxuu keenaa xogta cayriin, iyada oo loo marayo image ku saabsan screen monitor computer wargelinaysaa natiijada xisaabaha.
Kaasi waa nooca wada hadalka. Marka la barbardhigo qaybaha yar gudaha, qalabka Waxanu uma suurtoobaan in aan aragto, sidaa darteed fikradda guud waxaa ka mid ah waa at qof kasta. Iyadoo this article waxaan ku darsato saldhigga aqoonta, aragti dhaw at nooc oo ah kormeerayaasha.

Iyada oo ku xidhan noocyada loo isticmaalo screen dhammaan qalabka bandhigay sida loo qaybin karaa laba kooxood oo waaweyn - dareeraha-crystal casriga ah (LCD, midableh, LCD), iyo ku dhawaad laga saaro wax soo saarka mass, cathode-ray (CRT, CRT). Mararka qaarkood liiska nooca saddexaad kaabaha - LCDs, laakiin waa soo jiidasho leh xal u gaar ah ma aha kuwo si sax ah u baahsan. Sayidka, barashada noocyada kormeerayaasha ku kooban LCD iyo CRT.

Dhab ahaantii, dad badan ayaa weli la xasuusto sida telefishanka eegto in bilowga ah "Zaman Quruurado ah ee dareeraha ah." Waxay ahaayeen qalab arrin weyn, shaashadda in ka fog kaamil ah oo siman ahaa. Inkastoo sanadihii ugu dambeeyey xaaladda saaraysa si muuqata u bedelay. Yaa ayaa fursad u helay si uu u eego gudaha TV jirka CRT ah, ogaadana in ku dhawaad mugga oo dhan degan tube cathode ray ah, meesha muuqaalkii iyo size, oo loox gacanta ku dhif dhaafto ee warqada. xidhiidhka ka dhexeeya monitor iyo TV qudheedu ay isticmaalaan mabda'a isku mid ah hawlgalka. Dabcan, farsamada isku-soo-saarka.

Ka fiirsaneysa noocyada kormeerayaasha in aan la iska indho tiri karin muuqaalada ama go'aankaas. Sidaas darteed, waxaan ku qor faa'idoyinka kormeerayaasha CRT :

- iibsiga ku dhowaad fiican oo dhan midabada, xataa model heerka entry saaraysa waa fog ka hor kormeeraha LCD qaali ah;

- la'aanta ah ee xaglo daawashada - sawirka shaashadda had iyo jeer waa la arki karo, iyadoo aan loo eegayn sida uu u dhaco on line ah hortiisa;

- pixels dhintay, jeedal oo dhan technology crystal dareere, CRT ah ma noqon karo lagu daydo,

- waxaa jira dhibaato ah ma leh image sifaynta halka bandhigeen tallaabo degdeg ah.

Laakiin kormeerayaasha LCD faano views of sifooyinka aad u kala duwan:

- heerka u hooseeya ee awoodda dhaxe, qiimaha caadiga ah waa 40 W (is barbar 80 iyo CRT a);

- dhinacyada is haysta iyo miisaanka yar yahay, oo sidaas daraaddeed si ay meel u qalab noocan oo kale ah oo derbiga dul, uma baahna si loo soo dajiyo qaab-dhismeedka ganaax weyn;

- load si xooga yar on indhaha: inta jeer flicker nidaamka Nuur ugu yar waxa ku sugan boqolaal megahertz (hafray lid ku sameeyay, sababta oo ah joogitaanka of regulation PWM, weli waa la heli karo);

- fiican Hufnaan image iyo maqnaanshaha dhibaato khalda alwaaxdii saqafka haysay at hal dhibic, iyo sidoo kale geometry awood dhalanrog.

Kormeerayaasha LCD waxay leeyihiin tiro ka mid ah sifooyinka maqan CRT yihiin. Tan waxa u sabab farqiga aad u ballaaran ee technology. Tusaale ahaan, noocyada soo socda ee kormeerayaasha matrices: The TN ugu badan, IPS sare, beddelka kala duwan ee VA ah. Mid kasta oo iyaga ka mid ah ayaa kaliya muuqaalada iyada soo jireenka ah in ay muhiim u yihiin in la tixgeliyo marka wax iibsigu monitor LCD ah.
