Kuyatsa LED ndi chiyani? mitundu ya kuyatsa

Alimi kupanga TV anaziphunzitsa ogwiritsa zonse ndi umisiri watsopano kuti kuwongolera chifanizo cha HIV. Njira chiyanjanitso cha zowonetsera TV ndi zinthu LED kale katswiri makampani waukulu. Posachedwapa, gwero la chowala yowala ndi zofewa komanso akudutsa pa matebulo a matayala. Unikani nyota za chisankho otere ndi okonda kuyatsa miyambo zochokera LEDs, koma, ndithudi, wokongola kwambiri backlight LED-zowonetsera ma TV. The kwambiri chifukwa likugwirizana ndi zina zina zamakono nawonso ntchito pa chitukuko cha njira imeneyi.

The chipangizo kuyatsa

Polenga zigawo kuti litsatira backlight LED-magulu ntchito imene chingakhale cha zinthu zoyera anatsogolera mumtundu kapena luminescence, monga RGB. Komitiyi unalinganizidwa ndi masanjidwewo mwapadera kuti cigawo mu chipangizo chonyamulira chitsanzo yeniyeni. Childs, chakumbali ya zolumikizira gulu imakonzedwa, mmodzi amene amatipatsa mphamvu LED chiwalitsiro, pamene ena tinapangidwa kulamulira kasinthidwe opaleshoni ake. Komanso zigawo LED ntchito dalaivala wapadera, ntchito zimene zimagwiritsa Mtsogoleri wa.

Mu anamaliza mawonekedwe LED Mzere imakhala ndi mndandanda wa nyali kakang'ono amene olumikizidwa ku magulu zidutswa 3. Ndithudi, opanga musati amalangiza kusokoneza chipangizo matepi amenewa, koma mwina mwathupi adzafupikitsidwa kapena, Tikawonetsetsa kuchita chipangizo yaitali ngati n'koyenera. Komanso, unit LED-backlight chophimba amapereka mphamvu kusintha kuwala, amaziyang'anira yosalala poyambira ndipo zida ndi chitetezo voteji.

Gawo backlight kolowera mtundu

Pali njira ziwiri cigawo chiwalitsiro LED - mwachindunji ndi mapeto. Kasinthidwe choyamba kumafuna kuti khamu adzakhala ili kuseri kwa gulu madzi galasi. Yachiwiri limakupatsani kulenga woonda kwambiri mapanelo zowonetsera ndipo amatchedwa Kudera-LED. Mu nkhani iyi, kuyika kwa tepi padziko kukafika kutsogolo kwa mbali lamkati la kangoloko. Choncho yunifolomu kufalitsidwa kwa LEDs imachitidwa mwa gulu amene oyenerera kumbuyo LCD wa - amangoona mtundu wa backlight LED mafilimu ntchito mu chitukuko cha mafoni zipangizo. Otsatira mwachindunji backlight amasonyeza chifukwa Mkhalidwe wa luminescence, amene zimatheka ndi ambiri LEDs komanso kumathima m'dera kuchepetsa mtundu milozo.

Ntchito ya chounikira LED

Ogula pafupifupi mukhoza kupeza njira imeneyi mu zitsanzo za Sony ma TV, LG ndi Samsung, komanso mankhwala Kodak ndi Nokia. Inde, LEDs akhala ambiri, koma uli mwa zitsanzo za opanga awa akuona kusintha Mkhalidwe mu njira kukonza makhalidwe ogula nkhaniyi. Vuto lina lalikulu limene anakumana okonza ndi kuthandiza chophimba ntchito ndi makhalidwe akadakwanitsira mawu a dzuwa. Komanso, inatsogolera LED-backlight zaposachedwapa bwino mawu a kuwonjezeka mosiyana. Ngati tikukamba za kupita patsogolo mu njira ya dongosolo nsalu yotchinga, ndiye pali kuchepetsedwa kwambiri pa makulidwe a mapanelo, komanso ngakhale ndi chophimba lonse. Koma kukhalabe mavuto sanathetsedwe. LEDs sangathe mokwanira kukhala maluso awo m'kati kusonyeza zambiri. Komabe, izi sanaletse LED-luso aithamangitse CCFL-nyali ndi kupikisana ndi mbadwo watsopano wa zowonetsera plasma.

zotsatira mpumulo

Zigawo zochokera diodes kuwala emitting zambiri luso kupereka zotsatira zosiyana. Pa nthawi imeneyi chitukuko cha opanga luso zikukangalika ntchito njira ziwiri stereoscopic. The choyamba kupatuka okhota wa fluxes cheza mothandizidwa ndi mmene mapindidwe akuwala. wosuta kuona zotsatira mu njira ya kuonera ntchito magalasi kapena popanda iwo, ndiye mu mode holography. Zotsatira chachiwiri zikuphatikizapo kusamutsidwa kwa kamwazi wowala omwe amamasula magetsi LED anasonyeza kwa njira anakonzeratu mu zigawo madzi galasi. Ntchito njira imeneyi mukhoza pamodzi 2D ndi 3D-akamagwiritsa atatembenuka yoyenera kapena transcoding. Koma ponena osakaniza n'zotheka ndi zithunzi atatu azithunzi omwe tikunena ku backlights ndi LED Sapita bwino.

N'zogwirizana ndi luso 3D

Sitingathe kunena kuti chophimba ndi LED-backlit, pali mavuto aakulu a mogwirizana ndi mtundu 3D, koma mulingo woyenera maganizo a wowerenga ngati "chithunzi" amafuna magalasi apadera. Imodzi mwa madera kwambiri zingamuthandize chitukuko ichi ndi magalasi sitiriyo. Mwachitsanzo, akatswiri NVIDIA anamasulidwa zaka zingapo zapitazo shutter 3D magalasi ndi magalasi madzi galasi. Pakuti deflecting kuwala matabwa LED-backlight LCD chophimba amapereka ntchito Zosefera kugawanika. Pankhaniyi, mfundo akutsatiridwa popanda chimango wapadera, mu mawonekedwe a tepi. Ophatikizidwa mandala imakhala osiyanasiyana a translucent magulu LED, zomwe kuzindikira mfundo ndi chipangizo ulamuliro.

ubwino backlight ndi

Poyerekeza ndi zina zimene mungachite kuunikira, LEDs kwambiri kusintha khalidwe la zowonetsera ogula TV. Makamaka bwino makhalidwe mwachindunji fano - zimenezi zimachititsa kuwonjezeka Mosiyana ndi mtundu kubalana. The wapamwamba kwambiri mtundu sipekitiramu processing amapereka RGB-masanjidwewo. Komanso, LED-backlight osiyana otsika mowa mphamvu. Ndipo mwana'yo magetsi mowa kuchepetsa mpaka 40% zina. Komanso Dziwani ndi kuthekera yopangira zowonetsera ultrathin, imene pa nthawi yomweyo ndi kulemera otsika.

zolakwa

Anthu ma TV pano ndi backlight LED amawanena kuti zotsatira zoipa cheza buluu violet pa maso. Komanso bluish anati mu kwambiri "m'chifanizo" amene asokoneza zachilengedwe mtundu kubalana. Komabe, atsopano mabaibulo TV ndi mkulu -resolution LED-backlight chophimba ali pafupifupi munthu yopanda chilema. Koma pali mavuto ndi kasamalidwe kuwala, imene zimachitika mtsikana m'lifupi kusinthasintha mawu. Zoikamo zimenezi, mungaone chophimba kukulowa.

Pomaliza

Pakali pano, zitsanzo gawo TV ndi LED-luso ndi mu Chiyambi chake. Ngakhale ogula amayankha mwayi ndi ulemu, okhoza kupereka yankho nzeru. Tikumbukenso kuti kuipa ntchito wogwidwa anatsogolera anatsogolera-kuwala, osati kusokoneza owerenga mtengo monga mkulu. Akatswiri ambiri, chinthu ichi imatengedwa chotchinga yaikulu kwa popularization wa sayansi. Komabe, chiyembekezo cha LEDs akali zingamuthandize, monga mtengo awo adzakhala ndichepe monga kufunika ukuwonjezeka. Kufanana kwa izi ndi zina bwino kuyatsa quality, zomwe zina kumawonjezera chikoka cha kupereka.
