Chiwonetsero chaching'ono cha LED cholunjika chimagwira ntchito bwino kwambiri kuposa LCD

Kachipangizo kakang'ono ka LED chitukuko mpaka pano, ndi ukadaulo wokhwima kwambiri, kuwala kwake kwakukulu, kusiyana kwakukulu, mitundu yosiyanasiyana ndi makhalidwe ena pang'onopang'ono zadziwika kwambiri ndi ogula. Komabe, zakhala zovuta kuchotsa malingaliro olakwika a "ogwiritsa ntchito mphamvu" a LED.

Kotero, kodi stereotype ya Mini LEDKodi kugwiritsa ntchito mphamvu zambiri kumachokera kuti?

Kumbali imodzi, ma LED chips achikhalidwe ndi akuluakulu komanso osagwira ntchito bwino. Chowonetsera cha LED chofala kwambiri m'moyo watsiku ndi tsiku chikadali chiwonetsero cha SMD LED cha tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono. Chowonetsera cha SMD chamtunduwu chimapangidwa ndi phukusi labwino la mikanda yowala, chip yowala yomwe imagwiritsidwa ntchito mu mikanda ya nyali ndi yayikulu kwambiri kuposa Mini LED chip, ndipo mphamvu yowala komanso mphamvu yotaya kutentha ndizochepa kwambiri.

Chip ya Mini LED flip ili ndi kuwala kwakukulu komanso mphamvu yowala kuposa chip chachikulu chomwe chimagwiritsidwa ntchito mu SMD yachikhalidwe (1010/1212/1515, ndi zina zotero); Chifukwa chake, pansi pa mikhalidwe yomweyi, Kachipangizo kakang'ono ka LED Kugwiritsa ntchito mphamvu ya flip chip nakonso n'kochepa.

Koma ma LED akunja amasiya chithunzithunzi. Kuwonetsera mwachindunji kwa LED m'munda wowonetsera mkati sikunatenge nthawi yayitali, ndipo tanthauzo lachikhalidwe la chiwonetsero chachindunji cha LED ndilofala kwambiri panja. Kuwonetsera konse kwamkati, kaya LCD kapena LED, kuwala kwa 200-400nit ndikokwanira, koma chifukwa cha zosowa zamalonda, kuwala komwe kumafunikira ndi LED yakunja kumakhala kokwera kambirimbiri kuposa kwamkati, kufika pa 8000 kapena ngakhale 10000nit, mphamvu zomwe zimagwiritsidwa ntchito mwachibadwa sizili zofanana. Ndipo dera la chophimba chapakhomo ndi lofanananso ndi la chophimba chamkati, kotero LED imasiya malingaliro akuti kutentha sikungokhala kwakukulu, komanso mphamvu zonse zomwe zimagwiritsidwa ntchito pazenera ndi zapamwamba kwambiri.

Nchifukwa chiyani kristalo yamadzimadzi imadya mphamvu zambiri kuposa malingaliro?

Chifukwa LCD Sizingazimitse gawo la backlight. Kuwonetsera kwa kristalo wamadzimadzi kumachitika ndi machitidwe awiri osiyana: backlight ndi yomwe imayang'anira kuwunikira, ndipo mamolekyu a kristalo wamadzimadzi amawongolera kusintha kwa mtundu, kuwala ndi mdima mwa kupotoza. Chifukwa chake, bola ngati LCD yayatsidwa, mosasamala kanthu kuti ndi chinsalu chiti chomwe chikuwonetsedwa, ngakhale chikhale chinsalu chakuda, gawo la backlight nthawi zonse lakhala lowala nthawi zonse komanso lokhazikika, ndipo silingasinthidwe kapena kutsekedwa momasuka.

Chiwonetsero cha LED cholunjika chimadziwunikira chokha ndi chip cha LED, kuwala ndi mtundu zimayendetsedwa mwachindunji ndi mphamvu ndi magetsi. LED Chip yomwe mukufuna kukwaniritsa, ma pixel akuda kuwala kochepa, kugwiritsa ntchito mphamvu zochepa, ma pixel akuda satulutsa kuwala, kugwiritsa ntchito mphamvu sikutha.
