Uyini Umehluko phakathi kwe-LED ne-Direct Luminescence

Umthombo we-backlight we-LED we-patch ekhanyayo eseceleni ukukhanya kwangemuva okwenziwe ngemithombo yokukhanya emise okwechashaza ehlangothini lohlangothi lwepuleti lomhlahlandlela wokukhanya okhethekile. Inqubo yokukhanyisa i-backlight eqondile ilula. Ayidingi ibhodi eliqondisayo elikhanyayo. Iwukubeka umthombo wokukhanya (i-LED chip array) ne-PCB ngaphansi kokukhanya kwangemuva. Ngemuva kokudubula ukukhanya ku-LED I-membrane ihluma ngokulinganayo. Impendulo Yokunwetshwa: Uma umthombo wokukhanyisa i-LED usetshenziswa ku-LCD enosayizi omkhulu, isisindo nezindleko zebhodi lomhlahlandlela wokukhanya zizokhula ngosayizi, futhi ukukhanya okukhanyayo nokufana ngeke kube kuhle. Ngesikhathi esifanayo Ngenxa yokuthi ama-TV e-LCD awakwazi ukufinyelela ukulawula okuguquguqukayo kwesifunda kwama-LCD TV, angafinyelela kuphela ukulungiswa kokukhanya okune-dimensional eyodwa, kuyilapho ukusebenza kwe-backlight ye-LED eqondile kungcono. Ingakwazi ukuzuza ukulawula okuguquguqukayo kwesifunda kwe-LCD TV. I-backlight yokukhanya eseceleni ingaba mncane kakhulu, kodwa izinga lokusebenzisa ukukhanya komthombo we-backlight lincane, futhi lincane izinga lokusebenzisa, lincane izinga lokusebenzisa. Umnyombo wobuchwepheshe bayo ukuklama nokukhiqizwa kwebhodi lomhlahlandlela wokukhanya. Njengamanje, kunezinhlobo ezimbili zokuphrinta nokudubula ukwakha izimo. Ngendlela yebhodi yomhlahlandlela wokukhanya, okunye okufana nokubumba ukudubula kanye nokuphrinta, amachashazi e-laser, ukugqwala, njll., azilungele izimiso zokukhiqiza iqoqo. Izinzuzo zobuchwepheshe be-backlight eqondile ziyi-high-profile, i-angle enhle yokubuka i-outlet, ukusebenza kahle kokusetshenziswa kokukhanya okuphezulu, isakhiwo esilula, njll. Gcina isikhala esithile phakathi kwe-diffuser nomthombo wokukhanya we-LED ukuze uthuthukise ukufana kokukhanya. Ngakho-ke, ukukhanya okungemuva okuqondile nakho kwandisa ukushuba, isisindo, kanye nokusetshenziswa kwamandla kwemojuli. Ngakho-ke Light backlight.
