LCD splicing (madzimadzi crystal splicing)
LCDChiwonetsero cha kristalo chamadzi ndi chidule cha Liquid Crystal Display.Kapangidwe ka LCD ndikuyika makhiristo amadzimadzi pakati pa magalasi awiri ofanana.Pali mawaya ang'onoang'ono oyima ndi opingasa pakati pa zidutswa ziwiri za galasi.Mamolekyu a kristalo ooneka ngati ndodo amayendetsedwa ndi magetsi kapena ayi.Sinthani kolowera kuti musinthe kuwala kuti mupange chithunzi.LCD imakhala ndi mbale ziwiri zamagalasi, pafupifupi 1 mm wandiweyani, olekanitsidwa ndi nthawi yofanana ya 5 μm yokhala ndi zinthu zamadzimadzi.Chifukwa chakuti zinthu zamadzimadzi za kristalo sizimatulutsa kuwala, pali nyali kumbali zonse ziwiri za chinsalu chowonetsera ngati gwero la kuwala, ndipo pali mbale ya backlight (kapena mbale yowala) ndi filimu yowonetsera kumbuyo kwa chophimba chamadzimadzi. .Chipinda cha backlight chimapangidwa ndi zida za fulorosenti.Ikhoza kutulutsa kuwala, ntchito yake yayikulu ndikupereka gwero lounikira lakumbuyo.
Kuwala komwe kumapangidwa ndi mbale yowunikira kumbuyo kumalowa mumadzi amadzimadzi amadzimadzi okhala ndi madontho masauzande amadzimadzi amadzimadzi amadzimadzi atadutsa gawo loyamba la polarizing.Madontho amtundu wa kristalo wamadzimadzi onse amakhala mu cell yaying'ono, ndipo selo limodzi kapena angapo amapanga pixel pazenera.Pali maelekitirodi mandala pakati mbale galasi ndi madzi crystal chuma.Ma electrode amagawidwa m'mizere ndi mizati.Pamsewu wa mizere ndi mizati, mawonekedwe ozungulira amadzimadzi amadzimadzi amasinthidwa ndikusintha magetsi.Zinthu za kristalo zamadzimadzi zimakhala ngati valavu yaing'ono yowala.Pansi pa zinthu zamadzimadzi za kristalo pali gawo loyang'anira dera ndi gawo loyendetsa dera.Pamene ma elekitirodi muLCDkupanga magetsi, mamolekyu amadzimadzi a kristalo adzapindika, kotero kuti kuwala komwe kumadutsako kumasinthidwa nthawi zonse, kenako kusefedwera ndi gawo lachiwiri la fyuluta wosanjikiza ndikuwonetsedwa pazenera.
LCD splicing (liquid crystal splicing) ndiukadaulo watsopano wolumikizirana womwe watulukira m'zaka zaposachedwa pambuyo pa DLP splicing ndi PDP splicing.Makoma ophatikizana a LCD amakhala ndi mphamvu zochepa, kulemera kwake, komanso moyo wautali (nthawi zambiri amagwira ntchito kwa maola 50,000), Kupanda ma radiation, kuwala kofananira, ndi zina zambiri, koma choyipa chake chachikulu ndikuti sichingadulidwe mosasunthika, chomwe ndi chomvetsa chisoni pang'ono. kwa ogwiritsa ntchito makampani omwe amafunikira zithunzi zowoneka bwino kwambiri.Popeza chophimba cha LCD chili ndi chimango chikachoka kufakitale, chimango (msoko) chimawonekera pomwe LCD ilumikizidwa palimodzi.Mwachitsanzo, chimango cha chophimba chimodzi cha 21-inch LCD nthawi zambiri chimakhala 6-10mm, ndipo msoko pakati pa zowonetsera ziwiri za LCD ndi 12- 20mm.Pofuna kuchepetsa kusiyana kwaLCDsplicing, panopa pali njira zingapo mu makampani.Imodzi ndi yopapatiza-kang'ono splicing ndipo ina ndi micro-slit splicing.Micro-slit splicing zikutanthauza kuti wopanga amachotsa chipolopolo cha LCD chophimba chomwe wagula, ndikuchotsa galasi ndi galasi.Komabe, njira imeneyi ndi yoopsa.Ngati chophimba cha LCD sichinaphatikizidwe bwino, chidzawononga mawonekedwe a LCD yonse.Pakalipano, opanga nyumba ochepa kwambiri amagwiritsa ntchito njirayi.Komanso, pambuyo 2005, Samsung anapezerapo wapadera LCD chophimba kwa splicing-DID LCD chophimba.DID LCD skrini idapangidwa mwapadera kuti ikhale yolumikizana, ndipo chimango chake chimapangidwa chaching'ono pochoka kufakitale.
Pakalipano, kukula kwa LCD kwa makoma ophatikizana a LCD ndi mainchesi 19, mainchesi 20, mainchesi 40, ndi mainchesi 46.Itha kugawanika pakufuna malinga ndi zosowa za makasitomala, mpaka 10X10 splicing, pogwiritsa ntchito kuwala kwa backlight kutulutsa kuwala, ndipo moyo wake umakhala wautali mpaka maola 50,000.Kachiwiri, madontho a LCD ndi ochepa, ndipo mawonekedwe a thupi amatha kufika mosavuta pamtundu wapamwamba;komanso, aLCDchophimba chimakhala ndi mphamvu zochepa komanso kutentha kochepa.Mphamvu ya chophimba cha 40-inch LCD ndi pafupifupi 150W, yomwe ili pafupi 1/4 yokha ya plasma., Ndipo ntchito yokhazikika, yotsika mtengo yokonza.
