Isibani sangemuva se-LED esiqondile
Uma kusetshenziswa izibani zangemuva ze-LED ezikhanyiswe ngomphetho kuma-LCD aphakathi namakhulu, isisindo kanye nezindleko zepuleti lokuqondisa ukukhanya kuzokhula ngokwanda kosayizi, futhi ukukhanya kanye nokufana kokukhishwa kokukhanya akulungile. Iphaneli yokukhanya ayikwazi ukufeza ukulawula okuguqukayo kwesifunda kwe-LCD TV, kodwa ingakwazi ukufeza kuphela ukufiphala okulula kobukhulu obubodwa, kuyilapho ukukhanya kwangemuva kwe-LED okukhanyiswe ngqo kusebenza kangcono futhi kungafeza ukulawula okuguqukayo kwesifunda kwe-LCD TV. Inqubo yokukhanya kwangemuva okuqondile... -
Isibani sangemuva se-LED esikhanyiswe ngomphetho
Ukukhanya kwangemuva kwe-LED kubhekisela ekusetshenzisweni kwama-LED (ama-diode akhipha ukukhanya) njengomthombo wokukhanya kwangemuva wesibonisi sekristalu eliwuketshezi, kuyilapho isibonisi se-LED sangemuva siwumthombo wokukhanya kwangemuva wesibonisi sekristalu eliwuketshezi kusukela kushubhu lokukhanya elibandayo lendabuko le-CCFL (elifana nezibani ze-fluorescent) kuya ku-LED (i-diode ekhipha ukukhanya). Umgomo wokuthatha izithombe wekristalu eliwuketshezi ungaqondwa kalula njengeqiniso lokuthi i-voltage yangaphandle esetshenziswa ukuphambukisa ama-molecule ekristalu eliwuketshezi izovimba ukucaca... -
I-LED encane
Ubuchwepheshe be-Mini LED buwubuchwepheshe obusha bokubonisa. Ngaphezu kokusetshenziswa kuma-TV, ubuchwepheshe be-Mini LED bungavela nakumadivayisi ahlakaniphile njengamathebhulethi, omakhalekhukhwini, kanye namawashi esikhathini esizayo. Ngakho-ke, lobu buchwepheshe obusha bufanele ukunakwa. Ubuchwepheshe be-Mini LED bungabhekwa njengenguqulo ethuthukisiwe yesikrini se-LCD sendabuko, esingathuthukisa ngempumelelo umehluko futhi sithuthukise ukusebenza kwesithombe. Ngokungafani nezikrini ze-OLED ezizikhanyisayo, ubuchwepheshe be-Mini LED budinga ukukhanya kwe-LED... -
ibha yokukhanya
Isibani sangemuva se-LED sibhekisela ekusetshenzisweni kwe-LED (i-diode ekhipha ukukhanya) njengomthombo wokukhanya kwangemuva wezikrini ze-LCD. Uma kuqhathaniswa nomthombo wokukhanya kwangemuva we-CCFL (i-cold cathode tube), i-LED inezici zokusetshenziswa kwamandla aphansi, inani eliphansi lama-calories, ukukhanya okuphezulu nokuphila isikhathi eside, okulindeleke ukuthi kuthathe indawo ngokuphelele yesistimu yokukhanya kwangemuva yendabuko eminyakeni yamuva. Ukukhanya kwangemuva kwe-LED kuphezulu, futhi ukukhanya kwangemuva kwe-LED ngeke kunciphe isikhathi eside. Ngaphezu kwalokho,...
