Unoziva here kusiyana kweLCD, LED uye OLED?

Chidzitiro chekuratidzira chinonzi chimwe chezvakanyanya kugadzirwa muzana remakore rechi20.

Hazvina kuwandisa. Upenyu hwedu hunobwinya nokuda kwechitarisiko chahwo.

Nekuvandudzwa kwesainzi uye tekinoroji, zviratidziro zvekuratidzira hazvichaganhurirwe pakushandiswa kweTV skrini.

Kutengeswa kwakakura-hukuruLED inoratidza masikirinitanga kupinda muhupenyu hwedu, senge mashopu, mabhaisikopo, inogona kuonekwa munzvimbo dzakasiyana siyana senge nzvimbo dzemitambo yemukati, uye panguva ino, LCD, LED, OLED uye mamwe mazwi ehunyanzvi ari kuramba ari munzeve dzedu, kunyangwe mazhinji. vanhu vanotaura nezvawo, asi vanhu vakawanda vanoziva zvishoma nezvawo.

Saka, ndeupi musiyano uripo pakati peLcd, led uye oled?

LCD,LED ZVINORATIDZAUye OLED

1, LCD

LCD ipfupi yeLiquid Crystal Display muChirungu.

Kune kunyanya TFT, UFB, TFD, STN uye mamwe marudzi. Chimiro chayo chinosanganisira bhora repurasitiki, bhora regirazi, furemu glue, girazi substrate, upper polarizer, directional layer, liquid crystal, conductive ITO pateni, conduction point, IPO electrode uye yakaderera polarizer.

Kutora LCD advertising screen semuenzaniso, inotora inonyanya kuzivikanwa TFT-LCD, iri nhete firimu transistor liquid crystal kuratidza. Chimiro chayo chekutanga ndechekuisa mvura yekristaro bhokisi mune maviri anoenderana girazi substrates, isa yakaonda firimu transistor (inonzi TFT) pane yakaderera substrate girazi, isa ruvara sefa pane yepamusoro substrate girazi, kutenderera kutenderera kwemvura crystal mamorekuru inodzorwa nechiratidzo. uye shanduko yemagetsi pane yakaonda firimu transistor, kuitira kuti uwane chinangwa chekuratidzira nekudzora kana mwenje wepolarized wepixel yega yega waburitswa kana kwete.

Iyo musimboti wekuratidzwa kwekristaro yemvura ndeyekuti kristaro yemvura ichaunza akasiyana mwenje maitiro pasi pekuita kweakasiyana voltages. Iyo liquid crystal display screen inoumbwa neakawanda emvura makristasi arrays. Mune monochrome liquid crystal display screen, kristaro yemvura ipixel (iyo diki diki inogona kuratidzwa pakombuta skrini), mune yemavara liquid crystal kuratidza skrini, pixel yega yega ine tsvuku, girini uye bhuruu mvura makristasi. Panguva imwecheteyo, inogona kutariswa kuti kune 8-bit register kuseri kwekristaro yemvura yega yega, uye kukosha kwerejista kunotarisa kupenya kweimwe neimwe yeatatu emvura crystal units, zvisinei, kukosha kwerejista hakurevi zvakananga. dhiraivha kupenya kwematatu emvura ekristaro mayunitsi, asi anowanikwa kuburikidza ne “palette. Hazvina musoro kushongedza pixel yega yega nerejista yemuviri. Muchokwadi, mutsara mumwe chete werejista wakashongedzerwa. Aya marejista akabatana kune imwe neimwe mutsara wemapikseli achitendeuka uye akaiswa mune zviri mukati memutsara uyu, tyaira mitsetse yese pixel kuratidza mufananidzo wakazara.

2, LED SCREENS

LED ipfupi yeChiedza Emitting Diode. Imhando ye semiconductor diode, iyo inogona kushandura simba remagetsi kuita chiedza simba.

Kana maerekitironi asanganiswa nemaburi, chiedza chinooneka chinogona kuvheneka, saka chinogona kushandiswa kugadzira chiedza chinobudisa madhiri. Kufanana nemadhiodhi akajairwa, mwenje emitting diode inoumbwa nepn junction uye zvakare ine unidirectional conductivity.

Nheyo yayo kana iyo yakanaka voltage inowedzerwa kune mwenje emitting diode, maburi akaiswa munzvimbo yeN kubva munzvimbo yeP uye maerekitironi akaiswa munzvimbo yeP kubva munzvimbo yeN, mukati memamicrons mashoma pedyo nePN junction, inosanganiswa. ane maerekitironi munharaunda yeN uye maburi ari munharaunda yeP zvichiteerana kuti abudise zvinongoerekana zvabuda mufluorescence.

Simba remaerekitironi nemakomba mune zvakasiyana semiconductor zvinhu zvakasiyana. Kana maerekitironi nemakomba aungana, huwandu hwesimba hunoburitswa hwakasiyana. Kuwanda kwesimba kunoburitswa, ndiko kupfupika kwewavelength yechiedza chinobudiswa. Inowanzoshandiswa madhidhiyo anobudisa chiedza chitsvuku, chiedza chegirini kana kuti yero.

LED inonzi chizvarwa chechina Chiedza Chitubu, chine hunhu hwekuchengetedza simba, kuchengetedzwa kwezvakatipoteredza, kuchengetedzwa, hupenyu hurefu hwebasa, kuderera kwesimba rekushandisa, kushoma kupisa, kupenya kwakanyanya, kusapinda kwemvura, miniature, shockproof, dimming nyore, concentrated light beam, kugadzirisa kuri nyore. , nezvimwewo, inogona kushandiswa zvakanyanya munzvimbo dzakasiyana siyana senge chiratidzo,Chiratidziro che LED, kushongedza, backlight, general lighting, nezvimwe.

Semuyenzaniso, chidzitiro che LED, Kushambadzira LED Screen, mwenje wetraffic chiratidzo, mwenje wemotokari, LCD backlight, mwenje wemba uye kumwe kunobva mwenje.

3, OLED

OLED ipfupi yeOrganic Light-Emitting Diode. Iyo inozivikanwawo se organic electric laser display, organic light emitting semiconductor.

Diode iyi yakawanikwa murabhoritari muna 1979 nemumwe purofesa wekuAmerica wekuAmerica Deng Qingyun.

OLED ine yekunze OLED yekuratidzira unit uye mwenje emitting zvinhu zvakasungirirwa mairi, zvinosanganisira cathode, emission layer, conductive layer, anode uye base. Imwe neimwe OLED inoratidzira unit inogona kudzora kuburitsa mwenje wemavara matatu akasiyana.

OLED yekuratidzira tekinoroji ine hunhu hwekuzvivheneka, uchishandisa yakaonda kwazvo organic material coating uye girazi substrate. Kana paine kutenderera kwemagetsi, izvi organic zvinhu zvinoburitsa mwenje, uye yekuona kona yeOLED kuratidza skrini yakakura, uye inogona kuchengetedza mashandisiro emagetsi. Kubva 2003, iyi tekinoroji yekuratidzira yakashandiswa kune MP3 mimhanzi vatambi.

Mazuva ano, mumiriri ane mukurumbira weOLED application ndiyo nharembozha skrini. OLED skrini inogona kuratidza yakanyatso mutsauko wemifananidzo, uye iyo yekuratidzira pikicha ichave yakajeka uye yechokwadi. Nekuda kwehunhu hwekristaro yemvura, LCD skrini haitsigire kukotama. Mukupesana, OLED inogona kugadzirwa kuita yakakombama skrini.

Kusiyana Pakati peVatatu

1, Pamusoro pemavara gamut

OLED skrini inogona kuratidza isingaperi mavara uye haina kukanganiswa nebacklights, asi LED Screen ine kupenya kuri nani uye yekuona kona.

Pixels ane mabhenefiti makuru kana achiratidza ese-matema mifananidzo, parizvino, iyo color gamut yeLCD skrini iri pakati pe72 ne92 muzana, nepo iyo led skrini iri pamusoro pe118 muzana.

2, maererano nemutengo

Masikirini e LED ehukuru hwakafanana anodhura zvakapetwa kaviri seLCD skrini mudiki pixel pitch led vhidhiyo madziro, nepo OLED skrini inodhura.

3, Panyaya ye tekinoroji yakakura yekupenya uye isina musono.

Chidzitiro che LED chiri nani kupfuura LCD skrini uye OLED mukupenya uye isina musono, kunyanya muhukuru hukuru inotungamirwa vhidhiyo mudhuri yekushambadzira skrini kana yemukati yekutengesa madhijitari masaini ekushandisa.

Ipo LCD kana OLED yehukuru hombe yedhijitari vhidhiyo madziro inoda kudzvanywa, mukaha uripo pakati pemapanera unozokanganisa kuita uye kunzwa kwemuoni.

4, Panyaya yekuita kwevhidhiyo uye kona yechiratidziro

Iyo chaiyo kuratidzwa ndeyekuti iyo yekuona kona yeLCD skrini idiki kwazvo, nepo LED skrini inogutsa mukugadzika uye ine simba kuita nehunyanzvi hwekuvandudza tekinoroji yekuratidzira inotungamira, nekuwedzera, kudzika kweiyo LED skrini kwakaringana kunyanya mu.YONWAYTECH yakamanikana pixel pitch led kuratidza mhinduro.
