LED Bonisa Ulwazi oluSiseko

1. Yintoni i-LED?
I-LED sisishunqulelo se-diode ekhupha ukukhanya. Umgaqo weteknoloji ye-LED luminescence kukuba izinto ezithile ze-semiconductor ziya kukhupha ukukhanya kwe-wavelength ethile xa kusetyenziswa okwangoku. Olu hlobo lombane kwimpumelelo yokuguqula ukukhanya luphezulu kakhulu. Unyango lweekhemikhali ezahlukeneyo lunokwenziwa kwizinto ezisetyenziselwa ukufumana ukukhanya okwahlukeneyo. Kwaye ukujonga i-angle ye-LED. Sisikrini esibonisa umbhalo, imizobo, imifanekiso, oopopayi, iikowuti zemarike, iividiyo, imiqondiso yevidiyo kunye nolunye ulwazi ngokulawula indlela yokubonisa ye-semiconductor light-emitting diode.

2. Izikrini zokubonisa i-LED ziquka ezi ntlobo zilandelayo.

Umboniso ogcweleyo we-LED wombala . Umbala opheleleyo ukwabizwa ngokuba yimibala emithathu ephambili, eyona yunithi incinci yokubonisa yenziwe ngemibala emithathu ephambili ebomvu, eluhlaza, kunye nebhlowu. Isikrini se-LED esinemibala egcweleyo sisetyenziswa ikakhulu kwizikhululo zeenqwelomoya, kwizikhululo zikaloliwe, kwiicinema, kudederhu lweevenkile nakwizigaba.

Umboniso we-LED onemibala emibini. Umboniso we-LED onemibala emibini ubukhulu becala unobomvu & eluhlaza, obomvu & bhlowu. Phakathi kwabo, obomvu kunye nohlaza zezona ziqhelekileyo. Imiboniso yemibala emibini isetyenziswa kakhulu kwezemali, kunxibelelwano, ezibhedlele, kukhuseleko loluntu, kudederhu lweevenkile, kwezemali nakwirhafu.

Umboniso we-LED omnye. Umboniso omnye we-LED unombala obomvu, omthubi, oluhlaza, oluhlaza, omhlophe. Umboniso we-LED wombala omnye usetyenziswa ikakhulu kwiipaki, iindawo zokupaka kunye neevenkile ezithengisayo.

Ngokuphuculwa komgangatho wokuphila, iimfuno zabantu ziyaqhubeka zisanda. Umbala omnye kunye nemibala emibini ye-LED iziboniso ziye zatshintshwa ngokuthe ngcembe ziziboniso ze-LED ezinombala ogcweleyo.

3. Ukwakheka okusisiseko komboniso.
Isikrini sokubonisa i-LED senziwe ngeekhabhinethi ze-LED (zinokuthi zihlanjululwe) kunye nekhadi lokulawula (ikhadi lomthumeli kunye nekhadi lokufumana). Ngoko ke, umlawuli wobungakanani obufanelekileyo kunye neekhabhinethi ze-LED zingenza ubungakanani obuhlukeneyo be-LED ukubonisa ukuhlangabezana neemfuno zeendawo ezahlukeneyo kunye neemfuno zokubonisa ezahlukeneyo.

4. Iiparamitha jikelele zesikrini se-LED.
Nye. Iimpawu ezibonakalayo
Ubume bePixel
Umgama phakathi kwamaziko eepikseli ezikufutshane. (Iyunithi: mm)

Ukuxinana
Inani leepixels kwiyunithi yendawo nganye (iyunithi: amachaphaza/m2). Kukho unxulumano oluthile lokubala phakathi kwenani leepikseli kunye nomgama phakathi kweepikseli.
Ifomula yokubala ithi, ingxinano=(1000/pixel umgama osembindini).
Ukuphakama koxinano lweUmboniso we-LED, umfanekiso ocacileyo kunye nomncinci umgama obalaseleyo wokujonga.

Ukucaba
Ukutenxa ngokungalingani kweepikseli kunye neemodyuli ze-LED xa uqulunqa isikrini sokubonisa i-LED. I-flatness elungileyo yesikrini sokubonisa i-LED akulula ukwenza ukuba umbala wesikrini se-LED ungalingani xa ubukele.

Mbini. Iimpawu zokusebenza kombane
Isikali esingwevu
Inqanaba lokuqaqamba elinokwahlulwa ukusuka kowona mnyama ukuya kowona uqaqambileyo kwinqanaba elifanayo lokuqaqamba kwesiboniso se-LED. Isikali esingwevu ikwabizwa ngokuba sisikali sombala okanye isikali esingwevu, esibhekisa kwiqondo lokuqaqamba. Kwitekhnoloji yokubonisa idijithali, i-grayscale yeyona nto ibalulekileyo kwinani lemibala ebonisiweyo. Ngokuqhelekileyo, okukhona inqanaba liphezulu elingwevu, kokukhona ityebile imibala ebonisiweyo, kokukhona ucekeceke ngakumbi umfanekiso, kwaye kokukhona kuba lula ukuchaza iinkcukacha ezityebileyo.

Inqanaba elingwevu lixhomekeke ikakhulu kutshintsho lwenkqubo yeA/D bits. Ukwahlulwe ngokubanzi kungabikho greyscale, 8, 16, 32, 64, 128, 256 amanqanaba njl., Okukhona uphezulu inqanaba elingwevu lomboniso we-LED, umbala otyebileyo, kunye nombala oqaqambileyo.

Okwangoku, umboniso we-LED wamkela ikakhulu inkqubo ye-8-bit, oko kukuthi, ama-256 (28) amanqanaba angwevu. Ukuqonda okulula kukuba kukho 256 utshintsho lokukhanya ukusuka kumnyama ukuya kumhlophe. Ukusebenzisa imibala emithathu ephambili ye-RGB inokwenza i-256×256×256=16777216 imibala. Oko kubizwa ngokuqhelekileyo njengemibala ye-mega eyi-16.

Hlaziya ifreyim rhoqo
Umboniso we-LED ubonisa ulwazi lwesikrini sohlaziyo rhoqo.
Ngokubanzi, yi-25Hz, 30Hz, 50Hz, 60Hz, njl. Ukuphakama kwesakhelo sokutshintsha rhoqo, kungcono ukuqhubeka komfanekiso otshintshileyo.

Hlaziya rhoqo
Umboniso we-LED ubonisa inani lamaxesha idatha iboniswa ngokuphindaphindiweyo ngesibini.
Idla ngokuba yi-960Hz, 1920Hz, 3840Hz, njl. Okukhona uphezulu izinga lokuhlaziya, kokukhona uzinze ngakumbi umboniso womfanekiso. Xa ifoto, ireyithi yokuhlaziya eyahlukileyo inomahluko omkhulu.

5. Inkqubo yokubonisa
Inkqubo yodonga lwevidiyo ye-LED yenziwe ngamacandelo amathathu, umthombo wesignali, inkqubo yokulawula kunye nomboniso we-LED.
Inkqubo yokulawula umsebenzi oyintloko kukufikelela komqondiso, ukuguqulwa, inkqubo, ukuhanjiswa kunye nokulawula umfanekiso.
Isikrini esikhokelwayo sibonisa umxholo womthombo wesiginali.
