Tare da ci gaba da ci gaban kimiyya da fasaha a cikin 'yan shekarun nan, an gane alamun LED kuma an yi amfani da su a masana'antu daban-daban. Abubuwan da aka nuna suna ƙara ƙara girma-ma'ana. Ta yaya nunin LED zai iya cimmanuni mai ma'ana ? Na farko, hoton da tushen bidiyo yana buƙatar cikakken HD. Na biyu, ana buƙatar nunin LED don tallafawa cikakken HD. Na uku shine don rage girman pixel na nunin LED. Na huɗu shine haɗin nunin jagora da na'urar sarrafa bidiyo. A halin yanzu, nunin cikakken launi na LED shima yana motsawa zuwa nunin ma'ana mafi girma.
1, Haɓaka rabon bambanci na cikakken launi LED nuni. Matsakaicin bambance-bambance shine ɗayan mahimman abubuwan da ke shafar tasirin gani. Gabaɗaya magana, mafi girman bambanci, mafi kyawun hoto da haske mai launi. Babban bambanci yana da taimako sosai don tsabtar hoto da aikin matakin launin toka. A wasu rubutu da nunin bidiyo tare da babban baƙar fata da fari, babban nuni mai cikakken launi LED nuni yana da fa'idodi a cikin baƙar fata da fari, kaifi, da mutunci. Bambanci yana da babban tasiri akan tasirin nuni na bidiyo mai ƙarfi. Saboda hasken haske da duhu a cikin hotuna masu tsauri yana da sauri da sauri, mafi girman bambanci, mafi sauƙi ga idanun ɗan adam don bambanta irin wannan tsarin canji. A gaskiya ma, haɓakawa na bambanci na cikakken launi LED allon shine yafi don inganta haske na cikakken launi na LED nuni da kuma rage hasken fuskar fuska. Duk da haka, hasken ba shi da girma kamar yadda zai yiwu, yana da girma sosai, amma zai zama mara amfani, ba kawai yana rinjayar nunin LED ba. rayuwa, amma kuma yana haifar da gurɓataccen haske. The RGB LED nuni LED module da LED haske-emitting tube sha na musamman aiki, wanda zai iya rage reflectivity na LED panel da kuma inganta bambanci na RGB LED nuni.
2, Inganta matakin launin toka na bangon bidiyo na LED mai cikakken launi. Matsayin launin toka yana nufin matakin haske wanda za'a iya bambanta daga mafi duhu zuwa mafi haske a cikin hasken launi na farko na nunin LED mai cikakken launi. Mafi girman matakin launin toka na nunin LED mai cikakken launi, mafi kyawun launi da haske mai launi. Haɓaka matakin launin toka na iya haɓaka zurfin launi sosai, don haka matakin nuni na launi na hoto yana ƙaruwa da geometrically. The LED launin toka sikelin iko matakin ne 14bit ~ 20bit, wanda ya sa image matakin da cikakken bayani dalla-dalla da nunin tasirin high-karshen nuni kai ga duniya ci-gaba matakin. Tare da haɓaka fasahar kayan masarufi, sikelin launin toka na LED zai ci gaba da haɓaka zuwa daidaitaccen iko.
3, Rage farar pixel na cikakken launi LED nuni. Rage farar pixel na nunin LED mai cikakken launi na iya haɓaka tsabtarsa sosai. Karamin ɗigon ɗigon nunin LED mai cikakken launi, mafi kyawun nuni. Duk da haka, farashinkananan-fiti LED nuni yana kan babban gefe. Abin farin ciki, kasuwa yanzu yana tasowa zuwa ƙananan nunin LED.
4, LED nuni hade da video processor. Mai sarrafa bidiyo na LED na iya amfani da algorithms masu ci gaba don canza siginar tare da ingancin hoto mara kyau, aiwatar da jerin ayyuka kamar de-interlacing, ƙwanƙwasa gefen, ramuwa na motsi, da sauransu, don haɓaka cikakkun bayanai na hoton da haɓaka ingancin hoto. Ana amfani da algorithm na sarrafa hoton bidiyo don tabbatar da cewa bayan an daidaita hoton bidiyon, ana kiyaye tsabta da launin toka na hoton zuwa mafi girma. Bugu da kari, na'urar sarrafa bidiyo kuma tana buƙatar samun wadatattun zaɓuɓɓukan daidaita hoto da tasirin daidaitawa, da aiwatar da haske, bambanci, da launin toka don tabbatar da cewa allon yana fitar da hoto mai laushi da haske.
