LCD ndi dzina lathunthu la Liquid Crystal Display, makamaka TFT, UFB, TFD, STN ndi mitundu ina ya ma LCD owonetsera sangathe kupeza zolowetsa pulogalamu pa laibulale ya Dynamic-link.
Chojambula chodziwika bwino cha LCD cha laputopu ndi TFT.TFT (Thin Film Transistor) imatanthawuza transistor yopyapyala ya filimu, pomwe pixel iliyonse ya LCD imayendetsedwa ndi transistor yopyapyala yophatikizidwa kuseri kwa pixel, yomwe imathandizira kuthamanga kwambiri, kuwala kwakukulu, komanso kuwonetsa zambiri zazithunzi.Pakali pano ndi chimodzi mwa zida zabwino kwambiri zowonetsera mtundu wa LCD komanso chida chowonetsera pakompyuta ndi pakompyuta.Poyerekeza ndi STN, TFT ili ndi machulukidwe abwino kwambiri amtundu, kuthekera kobwezeretsa, komanso kusiyana kwakukulu.Zitha kuwoneka bwino kwambiri padzuwa, koma kuipa kwake ndikuti zimadya mphamvu zambiri komanso zimakhala ndi mtengo wapamwamba.
Kodi LED ndi chiyani
LED ndiye chidule cha Light Emitting Diode.Mapulogalamu a LED akhoza kugawidwa m'magulu awiri: choyamba, zowonetsera za LED;Chachiwiri ndi kugwiritsa ntchito chubu limodzi la LED, kuphatikizapo kuwala kwa LED, kuwala kwa LED, ndi zina zoteroMawonekedwe a LED , Mulingo waukadaulo waku China wopangidwa ndiukadaulo umagwirizana kwambiri ndi miyezo yapadziko lonse lapansi.Chowonetsera chowonetsera cha LED ndi pepala lokonzekera makompyuta lomwe lili ndi 5000 yuan, lopangidwa ndi magulu a LED.Imatengera kuwunika kwamagetsi otsika ndipo imakhala ndi mawonekedwe akugwiritsa ntchito mphamvu zochepa, moyo wautali wautumiki, mtengo wotsika, kuwala kwakukulu, zolakwika zochepa, ngodya yayikulu yowonera, komanso mtunda wautali wowonera.
Kusiyana pakati pa LCD screen screen ndi LED display screen
Mawonekedwe a LEDali ndi zabwino kuposa zowonetsera za LCD malinga ndi kuwala, kugwiritsa ntchito mphamvu, ngodya yowonera, komanso kutsitsimula.Pogwiritsa ntchito ukadaulo wa LED, ndizotheka kupanga zowonetsa zocheperako, zowala, komanso zomveka bwino kuposa ma LCD.
1. Mphamvu yogwiritsira ntchito mphamvu ya LED ku LCD ndi pafupifupi 1:10, zomwe zimapangitsa kuti LED ikhale ndi mphamvu zambiri.
2. LED ili ndi kutsitsimula kwapamwamba komanso kuchita bwino muvidiyo.
3. Kuwala kwa LED kumapereka mawonekedwe owoneka bwino mpaka 160 °, omwe amatha kuwonetsa zolemba zosiyanasiyana, manambala, zithunzi zamitundu, ndi makanema ojambula.Iwo akhoza kuimba mtundu kanema chizindikiro monga TV, kanema, VCD, DVD, etc.
4. Liwiro lazomwe zimachitika pazithunzi za LED ndi nthawi 1000 kuposa zowonera za LCD LCD, ndipo zimatha kuwonedwa popanda cholakwika ndi kuwala kwamphamvu, ndipo zimatha kutengera kutentha kwa -40 digiri Celsius.
Mwachidule, LCD ndi LED ndi njira ziwiri zosiyana zowonetsera.LCD ndi chinsalu chowonetsera chopangidwa ndi makhiristo amadzimadzi, pomwe LED ndi chophimba chopangidwa ndi ma diode otulutsa kuwala.
Kuwala kwa LED: Kupulumutsa mphamvu (30% ~ 50% zochepa kuposa CCFL), mtengo wapamwamba, kuwala kwakukulu ndi machulukitsidwe.
CCFL backlight: Poyerekeza ndi kuwala kwa LED, imagwiritsa ntchito mphamvu zambiri (zocheperapo kuposa CRT) ndipo ndizotsika mtengo.
Kusiyana kwazenera: Kuwala kwa LED kumakhala ndi mtundu wowala komanso machulukitsidwe apamwamba (CCFL ndi LED zili ndi magwero osiyanasiyana achilengedwe).
