Liquid crystal displays (LCD) chikamu chinokosha chemazuva ano maTV, masmartphones uye mahwendefa. MuLCD screens, light-emitting diodes (LEDs) inobudisa chiedza chichena chekumashure, chinozovhenekerwa kumuoni kuburikidza ne-ultra-thin liquid crystal layer. Iyo crystal layer inopatsanurwa muzvikamu zvakawanda (pixels), uye yavo yakasarudzika transmittance inogona kugadziridzwa nekushandisa electric field.Nenzira iyi, pixel imwe neimwe inobudisa chiedza nekupenya kwayo kwakasiyana (uye ruvara runoratidzwa kuburikidza nefirita yemavara).
Mune flat-panel maTV ane echinyakare LEDs, inodiwa backlight inogadzirwa nemazana e LEDs; sezvo LED imwe chete inoda nzvimbo yakakura, hazvibviri kuva nenzvimbo yakawanda.Kukanganisa kuri pachena: hazvibviri kuwana yunifomu yeLCD mwenje wekrini ine rough LED matrix.Naizvozvo, apo boka rekutanga rezvikwangwani rinotora tekinoroji nyowani yemini-LED yakabuda muna 2020, indasitiri iyi yakamutsa kufarira kukuru.Sezvo madiki-LED ari madiki kwazvo (0.05 kusvika 0.2 mm) achienzaniswa neachinyakare maLED, zvave kugoneka kugadzira backlights kubva kumakumi ezviuru e mini-LED mwenje. sources.Mini LEDs dzakasungirirwa kune dzinonzi nzvimbo dzekuvhenekesa, uko nzvimbo imwe neimwe ichiri diki kudarika ma LED echinyakare.Kuburikidza nekudzora kwakatariswa kwenzvimbo imwe neimwe, kana ichienzaniswa neyakajairwa ma LED, iyo backlight intensity inogona kudzorwa zviri nani.Naizvozvo, vataridzi veTV vanogona tarisira kusiyanisa kwakavandudzika uye kwakadzama vatema. Pamusoro pezvo, mini-LED tekinoroji yakanaka pakuburitsa yakanyanya kusimba renji (HDR) uye yakaderera simba rekushandisa.
Kugadzirwa kwe LEDs kana mini-LEDs kwakaomesesa kupfuura kupfava kwepamusoro kunoratidzwa nezvikamu-kunyanya nekuti mamwe matanho anodiwa ekugadzira anofanirwa kuitwa pasi pevacuum mamiriro.Munhanho yekutanga, iyo MOCVD (Metal Organic Chemical Vapor Deposition) maitiro anoshandiswa kupfekedza simbi organic layer pawafer.Mukuita uku, iyo yakaturikidzana inonamirwa kune iripo crystal lattice nenzira yakarongedzerwa neatomu: mashoma mashoma eatomic layers, anoitika kutora chimiro chekristaro chewafer. .Kuti ive nechokwadi chekuti coating haina chero tsvina, danho iri rinofanirwa kuitwa pasi pevacuum protection.Apa ndipo panopinda mutero wevalue-added tax.Mugadziri mukuru pasi rose weMOCVD systems-nemuzinda wekambani kuGermany, China, neUnited States-inovimba neVAT vacuum valves.
Kuti ibudise shanduko isina kunaka muLED, imwe yakawedzera-tete-tete inofanira kuiswa uye yozoiswa panzvimbo chaiyo.Iri basa rakaomarara rinoitwa zvakanyanya kuburikidza nekudyidzana kwemaviri eplasma-akakwenenzverwa mafirimu matete: plasma- enhanced chemical vapor deposition (PECVD) yekuisa zvidimbu, uye plasma kemikari yakaoma etching kuti ibvise zvishoma.Sezvo maitiro aya anofanirawo kuitwa pasi pemamiriro ekutsvaira, VAT vacuum valve inoitawo basa rinokosha pano.
Kana kubudirira kwechokwadi kuchiitika mune ramangwana, mavharuvhu eVAT anozova mumwe wavo. Mushure mezvose, maererano nenyanzvi, mini-LED ingori nzvimbo yekumira kune diki mwenje sosi: micro-LEDs.Kuenzaniswa nemamini-LEDs, aya Chokwadi madiki madiki madiki madiki kakapetwa ka50 kusvika ka100. Zvinoshamisa: Iyo diki diki yeLED yemazuva ano ine kureba kwepadivi kwe3 microns, inova zviuru zvitatu zvemillimeter! zvakasiyana, micro-LED tekinoroji inomiririra yechokwadi paradigm shift. Inofananidzwa neLCD skrini, (mini) maLED anoita basa risingataridzike rechipiri senzvimbo yemwenje sosi. Mune micro LED skrini, pixel yega yega inopenya, inodzima uye inogona kudzimwa zvachose.Iyo yekuwedzera backlight-uye yakabatana yehunyanzvi kusava nechokwadi-saka haichadiwi zvachose!
Kunyangwe Micro-LED iri diki, mhedzisiro yacho yakakura.Kuchinja kubva kudiki kuenda kumicro LED tekinoroji yakaunza mabhenefiti makuru.Zvimwe zvacho zvinoonekwa, senge hombe yeruvara, kupenya kwepamusoro, kusiyanisa kwakanyanya, uye nekukurumidza refresh mwero. zvakadai sekushandiswa kwesimba kwakaderera uye hupenyu hurefu, hazvibatike, asi zvakakosha zvakaenzana.Muchirevo chechinyorwa ichi, chizvarwa chitsva che LEDs chinogona kunge chiri chechokwadi chekuchinja mutambo.
VAT Group AG yakaburitsa izvi muna Zvita 14, 2021, uye ndiyo ine chekuita neruzivo rwuri mukati.
