Iimbono eziqhelekileyo eziphosakeleyo malunga nokuqaqambisa izikrini zobusuku

Nazi ezinye iimbono ezixhaphakileyo malunga neendawo ezibalaseleyo zobusuku

1. ICandelo lokukhanyisela nokukhanya

Okwangoku, ukuqaqamba okuphezulu, ukusebenzisa amandla aphantsi kunye nokungafani okuphezulu kunye nangaphezulu konke kulandelwa kwishishini lokukhanya kwe-crystal yekristali (LCD). Ke ngoko, abanye oosomashishini abajolisi kuphando lwesayensi kunye nezinto ezintsha, kodwa kwimbono yembono kunye nezixhobo zovavanyo.

Okokuqala, kwisixhobo:

A. I-A. I-Tester yeTyeinance Gester / Imitha ye-LUminances eqhelekileyo (abathengisi basebenzisa idatha evavanywe yimitha yesikhungo esiqhelekileyo sokutshintsha idatha ye-tister ye-Tesster, i-shoddy!)

B. Sebenzisa izixhobo zobungcali ukutshintsha ixabiso lokukhanya kwixabiso lokukhanyisela.

C. Izixhobo zengcali aziqinisekanga kakhulu.

D. Sukwahlulahlula kunye nokukhanya komthombo wokukhanya

Okwesibini kufumaneka: Abathengi bajongana neminye imibandela abayinyanzelekileyo, nokuba babone isikrini sikhanya okanye sikhanyisekile okanye sikhanyise. Ubunzulu (ukukhanya) luhlobo lombala wendalo, okanye unolwalamano nombala oqaqambileyo wendawo yombala. Kwindawo yombala welebhu, ukukhanya kuchazwa ukubonisa imvakalelo yokuqaqamba kwabantu. Ikhanyiso ichazwa njengokuqina kokukhanya (ukuthamba) kwiyunithi nganye yendawo eqikelelweyo yayo nawuphi na umphezulu womphezulu, kujongwa kwicala elinye. Iiyunithi ziinyawo ze-genert. Iyunithi i-Luxo (LX), engu-1m / m2. Kwaye inkcazo yokuqaqamba ibhekisa kumzimba otyhafileyo (umzimba obonakalayo) umphezulu womhlaba ophumeleleyo (of Stadous) amandla omzimba. Xa amehlo abantu ewabona umthombo wokukhanya ovela kwicala elinye, umyinge ophakathi kobunzulu bokukhanya kunye nendawo yokukhanya eyokukhanya "ebonwa" ngamehlo omthombo wobukhali, oko kukuthi, ubunzulu be iyunithi yendawo eqikelelweyo. Iyunithi yokuqaqamba yi-kendra / meter meter (CD / M2). Ukuqaqamba kukuqonda komntu ngobunzulu bokukhanya. Linani eliqinisekileyo. Ngokungafaniyo nokukhanya, inani elihambelanayo elichazwe yi-physics libanzi kakhulu. Ezi zinto zimbini zihlala zididekile kulwimi oluqhelekileyo lwemihla ngemihla. Ixabiso lekhanyano lichaphazeleka bubukhulu bendawo, ubude, ukuphakama, ukunciphisa ukusebenzela ukukhanya, inani lezibane, imele indawo yento ekhanyayo, inani lokukhanya. Ubungakanani bokukhanya kunolwazi olubonakalayo, lo mzekelo uBalo olulandelayo, i-100 le-100 ye-100 ye-100 ye-LM, ukuba ithathe i-flux ye-fluen isasazwe ngokulinganayo kwisiqingatha se-sche ngaba i-1 I-M kunye ne-5 m yexabiso lokukhanya linokufunyanwa ngokwala manyathelo alandelayo: I-Hismisphere nge-1 m yendawo ye-1 ye-1 ye-1 ^ 2 = 6.28 M2, i-M yexabiso lokukhanya yi: I-1200 lm / 6.28 M2 = 191 Lu. Ngokufanayo, indawo ye-hemisphere kunye ne-5m yile: 2 pi ^ 2 = I-2 = i-5 = i-MORMM / i-1200lm / 157 M2 = 7.64Ux. Iimveliso eziqaqambileyo aziyomveliso ezingcono, bonisa isikrini esikhanyayo sihlala siziva singakhululekanga, kwelinye icala, kulula ukwenza umahluko phakathi komnyama nomhlophe, echaphazela intsebenzo yombala kunye nengwevu. Ukonyusa ukuqaqamba kwesibonisi, kodwa kukuphucula umahluko wayo, kungenjalo umboniso uya kubonakala umhlophe phenomenon. Ukufakwa kokukhanya kubaluleke kakhulu. Nokuba ukukhanya kuyinto efanayo okanye akuhambelani kakhulu nobungakanani kunye noqwalaselo lwelitye elingasemva kunye nelokubonisa. Isikrini esikumgangatho ophezulu se-LCD sinekukuqaqamba okuphezulu, kuthambile kwaye kungekho phantsi, kwaye akukho ndawo ibonakalayo emnyama.

2. ICandelo leScreen LCD kunye nescreen esikhokelweyo

Ukuqaqambisa abathengi bahlala bedibana kurhwebo lwepaneli ye-LCD lathi ukugqabaza kwe-LCD, ukutshintsha kwe-LED kuyagxininiswa ukuba intengiso ye-LED ye-LED ye-LED ye-LED Ibonisi, ngelixa i-Latter Dot Screen discrix iscreen i-Diode ikhuphe i-Diode, eyayisakuba iboniswe ngokuthe ngqo kwizibane ze-LCD, kubalulekile ukuqaphela ishishini le-LCD Isikrini se-LED, enyanisweni, ngokwendlela yokungasemva kwaye ithathiwe, isikrini se-LCD (CCFL), isikrini se-LCFL), isikrini se-LCFL), isikrini se-LCFL Isilumkiso sentsusa sentsusa se-LCD ukuze sikhanyise, kunjalo, isikrini sokugqibela asikokutshintsha isibane sangasemva, iingxaki zezobuchwephesha ezinzulu kufuneka zinxibelelane nabavelisi be-LCD ehambelanayo.

3. chaza iscreen screen kunye nescreen sendibano

I-intshi ye-LG, uSamsung, i-AUO, i-Mits, i-47/72 intshi ye-intshi ye-GAO, i-AUO 55/65 i-It Gayo Line , kokukhona kuya kubangela ukuba ibalaselise intsimi yesicelo yendawo yekristale yekristale ibe mbi ngakumbi kwaye imfuno yemakethi yexabiso le-geoungbing ixabisa kakhulu, ikwayinto ye-LCD kwintengiso okanye ngaphakathi Uninzi lwendibano, kunye neeakhawunti zesabelo sentengiso esipheleleyo, ebizwa ngokuba siyigxininisa iNdibano yeSikrini se-Fuliang LCD kwi-Screen Screen Screen kwiScreen Screen kwiScreen Screen kwiScreen kwiScreen kwiScreen kwiScreen Kukuqaqambisa isikrini sokuqala), olunye uhlobo olunjani lwemeko yesakhiwo sokuqala sokutshintsha (usebenzisa kuphela umenzi we-LCD), ishishini le-LCD ye-LCD ngoku i-LCD yendibano ye-LCD yesikrini.
