Kodi mukudziwa kusiyana kwa LCD, LED ndi OLED?
Chowonekera chimatchedwa chimodzi mwazinthu zazikulu kwambiri zazaka za 20th.
Sizochulukira. Moyo wathu ndi waulemerero chifukwa cha maonekedwe ake.
Ndi chitukuko cha sayansi ndi zamakono, zowonetsera zowonetsera sizimangokhala pakugwiritsa ntchito ma TV.
Malonda akulu akuluMa LED amawonetsa mawonekedweyambani kulowa m'miyoyo yathu, monga malo ogulitsira, malo owonetsera mafilimu, amatha kuwoneka m'malo osiyanasiyana monga malo ochitira masewera a m'nyumba, ndipo panthawiyi, LCD, LED, OLED ndi mawu ena aluso akukhalanso m'makutu athu, ngakhale ambiri. anthu amakamba za izo, koma anthu ambiri sadziwa zambiri za izo.
Ndiye, pali kusiyana kotani pakati pa Lcd, led ndi oled?
LCD,Mawonekedwe a LEDndi OLED
1, LCD
LCD ndichidule cha Liquid Crystal Display mu Chingerezi.
Pali makamaka TFT, UFB, TFD, STN ndi mitundu ina. Kapangidwe kake kumaphatikizapo mpira wapulasitiki, mpira wagalasi, guluu wa chimango, gawo lapansi lagalasi, polarizer yapamwamba, wosanjikiza wowongolera, kristalo wamadzimadzi, mawonekedwe a ITO ochititsa chidwi, ma electrode a IPO ndi polarizer yotsika.
Kutengera LCD malonda chophimba monga chitsanzo, izo utenga odziwika bwino TFT-LCD, amene ndi woonda film transistor liquid crystal anasonyeza. kapangidwe kake ndi kuika madzi galasi bokosi mu magawo awiri ofanana galasi, anapereka woonda filimu transistor (ndiko TFT) pa m'munsi gawo lapansi galasi, anapereka mtundu fyuluta pa chapamwamba gawo lapansi galasi, kasinthasintha malangizo a mamolekyu amadzimadzi crystal imayendetsedwa ndi chizindikiro. ndi kusintha kwa magetsi pa transistor yopyapyala ya filimu, kuti mukwaniritse cholinga chowonetsera poyang'anira ngati kuwala kozungulira kwa pixel iliyonse kumatulutsa kapena ayi.
Mfundo yowonetsera kristalo wamadzimadzi ndikuti kristalo yamadzimadzi idzawonetsa mawonekedwe osiyanasiyana a kuwala pansi pa ma voltages osiyanasiyana. Chophimba chowonetsera chamadzimadzi chamadzimadzi chimakhala ndi mitundu yambiri yamadzimadzi. Mu chiwonetsero cha monochrome liquid crystal display, crystal yamadzimadzi ndi pixel (gawo laling'ono kwambiri lomwe lingathe kuwonetsedwa pakompyuta), pazithunzi zowonetsera zamadzimadzi zamadzimadzi, pixel iliyonse imakhala ndi makristasi ofiira, obiriwira ndi abuluu. Pa nthawi yomweyi, zikhoza kuganiziridwa kuti pali kaundula wa 8-bit kumbuyo kwa kristalo wamadzimadzi, ndipo mtengo wa kaundula umatsimikizira kuwala kwa magawo atatu amadzimadzi amadzimadzi, komabe, mtengo wa kaundula suli mwachindunji. yendetsani kuwala kwa mayunitsi atatu amadzimadzi amadzimadzi, koma amapezeka kudzera mu "palette. Ndizosamveka kukonzekeretsa pixel iliyonse ndi kaundula wamba. Ndipotu, mzere umodzi wokha wa kaundula uli ndi zida. Zolembera izi zimalumikizidwa ku mzere uliwonse wa ma pixel motsatana ndikulowetsedwa muzomwe zili mu mzerewu, kuyendetsa mizere yonse ya pixel kuti iwonetse chithunzi chonse.
LED ndi yachidule ya Light Emitting Diode. Ndi mtundu wa semiconductor diode, yomwe imatha kusintha mphamvu yamagetsi kukhala mphamvu yowunikira.
Ma elekitironi akaphatikizidwa ndi mabowo, kuwala kowonekera kumatha kuwunikira, kotero kungagwiritsidwe ntchito kupanga ma diode otulutsa kuwala. Monga ma diode wamba, ma diode otulutsa kuwala amapangidwa ndi pn junction komanso amakhala ndi unidirectional conductivity.
Mfundo yake pamene mpweya wabwino umawonjezeredwa ku diode yotulutsa kuwala, mabowo omwe amalowetsedwa m'dera la N kuchokera kudera la P ndi ma electron omwe amalowetsa m'dera la P kuchokera ku dera la N, mkati mwa ma microns ochepa pafupi ndi mphambano ya PN, amaphatikizidwa. ndi ma elekitironi m'chigawo cha N ndi mabowo m'chigawo cha P motsatana kuti apange fluorescence yotulutsa mowiriza.
Mphamvu za ma elekitironi ndi mabowo muzinthu zosiyanasiyana za semiconductor ndizosiyana. Pamene ma elekitironi ndi mabowo pawiri, kuchuluka kwa mphamvu anamasulidwa ndi osiyana. Mphamvu zambiri zikatulutsidwa, kuwala kotulutsa kuwala kumafupikitsa. Nthawi zambiri amagwiritsidwa ntchito ndi ma diode omwe amatulutsa kuwala kofiira, kuwala kobiriwira kapena kuwala kwachikasu.
LED imatchedwa Fourth generation Light Source, yomwe ili ndi makhalidwe opulumutsa mphamvu, kuteteza chilengedwe, chitetezo, moyo wautali wautumiki, kugwiritsa ntchito mphamvu zochepa, kutentha pang'ono, kuwala kwakukulu, madzi, kakang'ono, shockproof, dimming yosavuta, kuwala kokhazikika, kukonza kosavuta. , etc, itha kugwiritsidwa ntchito m'magawo osiyanasiyana monga chisonyezo,Chiwonetsero cha LED, zokongoletsa, backlight, kuunikira wamba, etc.
Mwachitsanzo, chophimba cha LED, Kutsatsa kwa LED Screen, nyali yamagalimoto, nyali yagalimoto, LCD backlight, kuyatsa kwapakhomo ndi zoyatsira zina.
3, OLED
OLED ndi yachidule ya Organic Light-Emitting Diode. Imadziwikanso kuti organic electric laser display, organic light emitting semiconductor.
Diode iyi idapezeka mu labotale mu 1979 ndi pulofesa waku China waku America Deng Qingyun.
OLED imakhala ndi mawonekedwe akunja a OLED ndi zida zotulutsa zowala zomwe zimayikidwamo, kuphatikiza cathode, emission layer, conductive layer, anode ndi maziko. Chiwonetsero chilichonse cha OLED chimatha kuwongolera kuti chipange kuwala kwamitundu itatu.
Tekinoloje yowonetsera ya OLED imakhala ndi mawonekedwe odziwunikira okha, pogwiritsa ntchito zokutira zakuthupi zoonda kwambiri komanso gawo lapansi lagalasi. Pakakhala kufalikira kwa magetsi, zida za organic izi zimatulutsa kuwala, ndipo mawonekedwe owonera a OLED skrini ndi yayikulu, ndipo amatha kupulumutsa mphamvu. Kuyambira 2003, luso lowonetserali lakhala likugwiritsidwa ntchito kwa osewera nyimbo za MP3.
Masiku ano, woimira wodziwika bwino wa pulogalamu ya OLED ndiye chophimba chamafoni. Chophimba cha OLED chimatha kuwonetsa kusiyana kwazithunzi, ndipo chithunzi chowonetsera chidzakhala chowoneka bwino komanso chenicheni. Chifukwa cha mawonekedwe a kristalo wamadzi, chophimba cha LCD sichigwirizana ndi kupindika. Mosiyana ndi izi, OLED imatha kupangidwa kukhala chophimba chopindika.
Kusiyana Pakati pa Atatuwo
1, Pa mtundu wa gamut
Chophimba cha OLED chimatha kuwonetsa mitundu yosatha ndipo sichimakhudzidwa ndi zounikira kumbuyo, koma Screen ya LED yowala bwino komanso yowonera.
Ma pixel ali ndi zabwino zambiri powonetsa zithunzi zakuda, pakadali pano, mawonekedwe amtundu wa skrini ya LCD ali pakati pa 72 ndi 92 peresenti, pomwe chiwonetsero cha LED chili pamwamba pa 118 peresenti.
2, Kutengera mtengo
Zowonetsera za LED za kukula kofanana ndizokwera mtengo kuwirikiza kawiri kuposa zowonetsera za LCD mu khoma laling'ono la pixel pitch led video, pamene zowonetsera za OLED ndizokwera mtengo kwambiri.
3, Pankhani yaukadaulo wokhwima wowala komanso wopanda msoko.
Chowonekera cha LED ndichabwino kwambiri kuposa chophimba cha LCD ndi OLED yowala komanso yopanda msoko, makamaka pakhoma lalikulu la makanema otsogola pazotsatsa kapena kugwiritsa ntchito zikwangwani zamalonda zamkati.
Pomwe LCD kapena OLED pamakhoma akulu akulu amakanema a digito omwe amafunikira kugawanika, kusiyana pakati pa mapanelo kumakhudza momwe amawonera komanso momwe amamvera.
4, Kutengera momwe mavidiyo amagwirira ntchito komanso mawonekedwe ake
Mawonetseredwe enieni ndiwakuti mawonekedwe azithunzi za LCD ndi ochepa kwambiri, pamene chophimba cha LED ndi chokhutiritsa pakuyika ndi ntchito yamphamvu ndi chitukuko cha teknoloji ya chiwonetsero cha LED, kuwonjezera, kuya kwa chophimba cha LED kuli bwino mokwanira makamaka muYONWAYTECH yopapatiza pixel pitch led LED resolution.
