Isibane sangasemva se-LED ngqo
Xa kusetyenziswa izibane ze-LED ezikhanyiswe ngomphetho kwii-LCD eziphakathi nezinkulu, ubunzima kunye nexabiso lepleyiti yesikhokelo sokukhanya ziya kwanda ngokonyuka kobukhulu, kwaye ukukhanya kunye nokufana kokukhanya akulunganga. Iphaneli yokukhanya ayinakukwazi ukulawula i-LCD TV yengingqi, kodwa inokufezekisa kuphela ukufiphala okulula okulinganayo, ngelixa i-LED backlight ekhanyiswe ngqo isebenza ngcono kwaye inokufezekisa ulawulo lwe-LCD TV yengingqi. Inkqubo yokukhanyisa ngqo... -
Isibane sangasemva se-LED esikhanyiswe ngomphetho
Isibane sangasemva se-LED sibhekisa ekusebenziseni ii-LED (ii-diode ezikhupha ukukhanya) njengomthombo wesibane sangasemva sesiboniso sekristale yolwelo, ngelixa isiboniso se-LED esikhupha ukukhanya singumthombo wesibane sangasemva sesiboniso sekristale yolwelo ukusuka kwityhubhu yesibane esibandayo se-CCFL (esifana nezibane ze-fluorescent) ukuya kwi-LED (i-diode ekhupha ukukhanya). Umgaqo womfanekiso wekristale yolwelo unokuqondwa ngokulula njengenyaniso yokuba i-voltage yangaphandle esetyenziswayo ukuthintela iimolekyuli zekristale yolwelo iya kuthintela ukucaca kwe... -
I-LED encinci
Itekhnoloji ye-Mini LED yitekhnoloji entsha yokubonisa. Ukongeza ekusetyenzisweni kwiiTV, itekhnoloji ye-Mini LED inokuvela nakwizixhobo ezikrelekrele ezifana neetablethi, iifowuni eziphathwayo, kunye neewotshi kwixesha elizayo. Ke ngoko, le teknoloji intsha ifanele ukuqwalaselwa. Itekhnoloji ye-Mini LED ingathathwa njengenguqulelo ephuculweyo yesikrini se-LCD sendabuko, esinokuphucula ngempumelelo umahluko kwaye siphucule ukusebenza komfanekiso. Ngokungafaniyo nezikrini ze-OLED ezizikhanyisayo, itekhnoloji ye-Mini LED ifuna ukukhanya kwe-LED... -
ibha yokukhanya
Isibane sangasemva se-LED sibhekisa ekusetyenzisweni kwe-LED (i-diode ekhupha ukukhanya) njengomthombo wokukhanya kwangasemva kwizikrini ze-LCD. Xa kuthelekiswa nomthombo wokukhanya kwangasemva we-CCFL (ityhubhu ye-cathode ebandayo), i-LED ineempawu zokusetyenziswa kwamandla aphantsi, ixabiso eliphantsi leekhalori, ukukhanya okuphezulu kunye nobomi obude, okulindeleke ukuba ithathe indawo ngokupheleleyo yenkqubo yokukhanya kwangasemva yendabuko kwiminyaka yakutshanje. Ukukhanya kwangasemva kwe-LED kuphezulu, kwaye ukukhanya kwangasemva kwe-LED akuyi kuncipha ixesha elide. Ngaphezu koko,...
