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 kwepikseli, eyenza isantya esiphezulu, ukukhanya okuphezulu, kunye nokubonisa umahluko ophezulu wolwazi 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 wokubonwa.
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).
