Waa maxay farqiga u of bandhigay?

Imperceptibly yimid waqti ay kormeerayaasha ku salaysan tuubooyinka ray cathode (CRT) ayaa gebi ahaanba la joojiyey ka gadhi dukaamada qalabka computer, bedelay dhigooda LCD ay. Aqoon la technology this, dadka inta badan ka heli qasan marka la eego, maadaama ay jiraan dhowr koob oo ah maado la mid ah. Si looga fogaado jahawareer kasta, ha oo kaliya ayaa loo caddeeyo this: LCD, LCD - oo dhan mid ka mid ah iyo technology crystal dareere isla halkii kala duwan. LCD waxay ka dhigan tahay Liquid Crystal Display. Si dadban, sidoo kale halkan loo saarin karaa in ereyga «midableh», waxay ka dhigan tahay isticmaalka transistors film dhuuban si loo xakameeyo furta. Tan iyo markii ay lama isticmaalo ee CRT ah, waxaa iska cad in midableh tixraaca iyo muujinaysaa on LCD ee.

Bedelaadda ah kormeerayaasha CRT jir ah LCD casriga ah, milkiilayaasha badan ayaa wajahay arrin la yaab - markii ugu horeysay ka dib markii guurka bilaabi doonaan in ay dhaawici indhaha, iyo qaar ka mid ah xitaa wejiga u huwadeen. Sidaa awgeed, su'aasha daba-- "Sidee ayaan u kormeeri Mudanayaasha indhahana." Network wuxuu bixiyaa tiro ka mid ah talooyinka, laakiin wax badan oo ka mid ah waa dhamaystirnayn, maxaa yeelay, sababta oo ah waxa dhacaya aad si xirfad leh iska fududaysto. Indeed, haddii la barbardhigo kormeeraha iyo iftiin on LCD iyo CRT teknoolajiyada yihiin fikradaha la mid ah, ka dibna ka raaxo indhaha marka la LCD ka shaqeeya? Ka dib oo dhan, waa in aanay noqon. Sababta dhabta ah ee daal isha waa in kormeerayaasha LCD flicker. Mabda 'hawlgalka ee ilayska dhaadheer Nuur ku salaysan siideeyn gaaska ee tube ah, xataa iyada oo casri-nalalka LED sidoo kale eller soo jireenka ah (akhrin of control PWM ee uu Kokes ku). Intaa waxaa dheer, midabka luminescence sida laambadood oo dioska- - adaanaha, waxa ay leedahay spectrum haleysan. "By isha" Waa la arki karin, laakiin receptors muuqaal ah ma lagu siri.

Guud ahaan, ka duwan ee kormeeraha - waa qiimo tiro ka dhigan ratio ee kala duwan dhalaalka dhibic ugu cadcad inay madow muqdiga. The xogta baasaboorka ayaa sheegay in qaab «xxx: y» kormeerayaasha. Dhab ahaantii, tani waa hab kale oo qoraal ah. Tusaale ahaan, la barbardhigo bandhigay of dhibic ugu luminance 300 cd / m2 iyo ugu yaraan 0.5 cd / m2 waa (300-0.5) /0.5 = 599: 1. Waxaa la rumeysan yahay in sare qiimaha farqiga, af ah sawirka. Tani waa qayb ahaan run, laakiin kaliya ilaa xad go'an, sida kor u koobi karayn keenaysaa in dhalanrog ka mid ah image ah (faahfaahsan iftiin on joojin a soo jeeda cad in ay garan). Haddii la barbardhigo ee kormeeraha aan si sax ah loo qaybiyay, waa mid ka mid ah sababaha dareenka of ciid indhaha marka aad bedesho CRT in LCD.

Ogow in dhammaan hababka la soo jeediyay in xuduuda u qaabeynta network waa shakhsi ahaan. user kasta waa inuu ka bedelaan, ku salaysan oo keliya shakhsi door bidayso. Waxaa la dhisay-in dejinta dhalaalka ah kormeeraha, kaas oo u ogolaanaya set si mug leh qiimaha ay dhalaalka iyo duwan, iyo gamma in nidaamka qalliinka Windows 7.

On desktop-ka, riix badhanka mouse xaq, raac ee "Xallinta Screen", ee "Samee qoraal oo kale oo waxyaabaha waaweyn ama yar" iyo "qalapka midabka". By gujinaya "Next", ka dib markii talada sayidkayga ah (halkan waxaa jira caawimaad faahfaahsan). Marka ay dhamaato aad la keentay doonaa reserved bandhigay ee noocyada on technology Nooca Cad ee tijaabada tilmaamaya "baruurta" line ugu saxda ah iyo waraaqaha.

Intaa waxaa dheer, in aad la qabsato kartaa monitor laftiisa. Si aad u soo bandhigaan duwan ee 20-40%, iyo gaaro luminance image oo tayo sare leh. Xaaladaha qaarkood, dhalaalka noqon kartaa siman yahay si eber, taas oo ah arrin la aqbali karo. heerkulka Color (weecasho ee spectrum huruud ah ama buluug ah) waa in la dhigay ku salaysan doorashada shakhsi. Waxaa la arkaa in ay ka badan towns huruud dabiiciga ah oo u dhiganta heerkulka midabka ah ee iftiinka qoraxda (6300 K). habab kala duwan si loo hagaajiyo image iyo saamiga la barbardhigo firfircoon ma ogola in ay si fiican u rights reserved kormeeraha, sidaa darteed waxaa lagama maarmaan ah inay is barbar dhigaan ee la wanaajiyey iyo hababka dabiiciga ah iyo dooran ugu fiican naftaada.
