I-LCD ligama elipheleleyo leLiquid Crystal Display, ubukhulu becala i-TFT, i-UFB, i-TFD, i-STN kunye nezinye iindidi ze-LCD zokubonisa azikwazi ukufumana amanqaku enkqubo kwilayibrari ye-Dynamic-link.
Iscreen seLCD esisetyenziswa ngokuqhelekileyo yiTFT.I-TFT (i-Thin Film Transistor) ibhekisela kwi-transistor yefilimu ebhityileyo, apho i-pixel ye-LCD nganye iqhutywa yi-transistor yefilimu ebhityileyo edityaniswe ngasemva kwe-pixel, eyenza isantya esiphezulu, ukukhanya okuphezulu, kunye nomboniso ophezulu wokuchasana kolwazi lwesikrini.Ngoku sesinye sezona zixhobo zibalaseleyo zokubonisa umbala weLCD kunye nesixhobo sokubonisa esiqhelekileyo kwiilaptop kunye needesktops.Xa kuthelekiswa ne-STN, i-TFT inombala obalaseleyo wokugcwala, amandla okubuyisela, kunye nokuchasana okuphezulu.Isenokubonakala ngokucacileyo elangeni, kodwa i-disadvantage kukuba idla amandla amaninzi kwaye ineendleko eziphezulu.
Yintoni i-LED
I-LED sisishunqulelo se-Light Emitting Diode.Izicelo ze-LED zinokwahlulwa zibe ngamacandelo amabini: okokuqala, izikrini zokubonisa i-LED;Okwesibini kukusetyenziswa ityhubhu eyodwa ye-LED, kubandakanywa ukukhanya kwe-LED, i-infrared LED, njlIzikrini zokubonisa i-LED , Uyilo lwaseTshayina kunye nenqanaba lobuchwephesha bemveliso lihambelana ngokusisiseko nemigangatho yamazwe ngamazwe.Isikrini sokubonisa i-LED ishidi lokucwangciswa kwekhompyutheni kunye neyunithi yokubonisa ye-5000 yuan, equka uluhlu lwe-LED.Yamkela i-low voltage scanning drive kwaye ineempawu zokusetyenziswa kwamandla aphantsi, ubomi benkonzo ende, ixabiso eliphantsi, ukukhanya okuphezulu, iimpazamo ezimbalwa, i-angle yokujonga enkulu, kunye nomgama omde wokubonwayo.
Umahluko phakathi kwesikrini se-LCD kunye nesikrini se-LED
Iziboniso ze-LEDzineengenelo ngaphezulu kweziboniso ze-LCD malunga nokuqaqamba, ukusetyenziswa kwamandla, i-engile yokujonga, kunye nezinga lokuhlaziya.Ngokusebenzisa itekhnoloji ye-LED, kuyenzeka ukwenza iziboniso ezibhityileyo, eziqaqambileyo, nezicace ngakumbi kuneLCD.
1. Umlinganiselo wokusetyenziswa kwamandla e-LED ukuya kwi-LCD malunga ne-1:10, okwenza i-LED isebenzise amandla ngakumbi.
2. I-LED inezinga eliphezulu lokuhlaziya kunye nokusebenza okungcono kwividiyo.
3. I-LED ibonelela nge-engile yokujonga ebanzi ukuya kuthi ga kwi-160 °, enokuthi ibonise isicatshulwa ezahlukahlukeneyo, amanani, imifanekiso yemibala, kunye nolwazi lwe-animation.Iyakwazi ukudlala imiqondiso yevidiyo enemibala efana neTV, ividiyo, iVCD, iDVD, njl.
4. Isantya sokusabela isici somntu ngamnye kwizikrini zokubonisa i-LED ngamaxesha angama-1000 kwi-LCD LCD izikrini, kwaye zinokujongwa ngaphandle kwempazamo phantsi kokukhanya okunamandla, kwaye ziyakwazi ukuziqhelanisa nobushushu obuphantsi -40 degrees Celsius.
Ukubeka nje, i-LCD kunye ne-LED zitekhnoloji ezimbini ezahlukeneyo zokubonisa.I-LCD sisibonisi sesikrini esenziwe ngeekristale zolwelo, ngelixa i-LED sisibonisi sesikrini esenziwe zii-diode ezikhupha ukukhanya.
Ukukhanya kwe-LED: Ukugcinwa kwamandla (30% ~ 50% ngaphantsi kweCCFL), ixabiso eliphezulu, ukukhanya okuphezulu kunye nokugcwala.
Ukukhanya kwe-CCFL ngasemva: Xa kuthelekiswa nokukhanya kwe-LED ngasemva, kudla amandla amaninzi (kusengaphantsi kakhulu kuneCRT) kwaye kuyabiza.
Umahluko wesikrini: Ukukhanya kwe-LED kunombala oqaqambileyo kunye nokugcwala okuphezulu (i-CCFL kunye ne-LED zinemithombo eyahlukeneyo yokukhanya kwendalo).
Ukwahlula njani:
