Musi wa5 Chivabvu, panguva yeko, paSID Academic Forum, Chen Faxiang, nyanzvi yehunyanzvi kuVisionox, akapa hurukuro huru yakakokwa uye akazivisa kuti Visionox yatungamira mukutanga mhinduro yekugadzira yakawanda ye tekinoroji yeALD (Atomic Layer Deposition) all-oxide inofamba zvakanyanya.

Vachitora maitiro eALD, Visionox yakasunda kufamba kwemagetsi ese e-oxide TFTs kupfuura 50 cm²/V·s uye yakabudirira kushandisa panel ye-oxide ye6.39-inch. Kuongorora kunoratidza kuti tekinoroji iyi yakambozadzisa zvinodiwa pakuita mafirimu, kugadzikana uye kufanana, zvichigadzira nzira itsva yeOLED backplanes inoenzanisa kushanda kwepamusoro, kushanda zvakanaka kwemaitiro uye kugona kukura kwakazara.

ALD Inovhura Denga Rinoshanda Zvakanyanya reTekinoroji YeOxyide Yose

Mukushandiswa kwetekinoroji yeOLED backplane, LTPS yagara ichitonga nzira yepamusoro-soro nekuda kwekufamba kwayo kwepamusoro-soro. Zvisinei, inotsamira zvakanyanya paExcimer Laser Annealing (ELA), iyo inosanganisira maitiro akaomarara uye mitengo yakakwira. Mhinduro dzechinyakare dzeoxide dzinoshanda zvakanaka munzvimbo huru asi dzinoganhurirwa nekufamba kwakaderera, zvichideredza kushandiswa kwadzo kubva kumashandisirwo epamusoro-soro. Kuunzwa kwemaitiro eALD kunopa mhinduro itsva kune dambudziko iri renguva refu reindasitiri.

ALD inonyanya kushandiswa pakugadzira firimu remhando yepamusoro. Kusiyana nePVD (Physical Vapor Deposition), iyo inoisa zvinhu mupurasitiki imwe chete, ALD inokura firimu remhando yepamusoro rimwe chete panguva imwe chete ine simba guru rekudzora padanho rega rega. Nekuda kweizvozvo, firimu remhando yepamusoro rinogadzirwa neALD rine ukobvu hwakakodzera, kupararira kwakafanana uye kugadzikana kwakanyanya, zvichiisa hwaro hwakasimba hwezvinhu zveTFTs dzeoxide dzinoshanda zvakanaka.

Kune madhiraivha ekuratidza kumashure, kufamba kwekutakura chinhu chikuru chekuenzanisa kugona kwekutyaira kweTFT, zvichikanganisa zvakananga kumhanya kwemhinduro yepixel, kushanda zvakanaka kwekuchaja uye kushanda kwekutyaira mune zviitiko zvine resolution yepamusoro. Nekushandisa maitiro eALD, Visionox yakawana kufamba kwegedhi rimwe chete kweanopfuura 50 cm²/V·s uye kufamba kwegedhi mbiri kunodarika 80 cm²/V·s kune maTFT ese ane oxide, kusvika padanho repamusoro pasi rose. Izvi zvinoreva kuti madhiraivha ese ane oxide yakakwana yekutyaira kune mashandisirwo madiki emhando yepamusoro. Visionox icharamba ichisimudzira kugadzirwa kwehunyanzvi uhu muchikamu chinotevera.

Zvinonyanya kukosha ndezvekuti, tekinoroji iyi ye "all-oxide" inopa kutyaira kwepamusoro pasina maitiro akaomarara eELA, zvichiita kuti basa rekugadzira rive nyore uye kuvandudza kushanda zvakanaka kwekugadzira.

Kukurumidza Kuvandudza, Mabhezeki Akamanikana, Kushandiswa Kwesimba Rakaderera — Kuvandudza Kushanda Kunowedzera Ruzivo rweKuratidza

Kufamba kwakagadziridzwa kunoshandura zvakananga kuva kuvandudzwa kunooneka muruzivo rwechiratidziro chemushandisi.

Chekutanga, mwero wepamusoro wekuzorodza. Pakushandisa chaiko, furemu yega yega inoda kuzorodza mapikiseli mukati menguva pfupi. Kugona kwakasimba kwekutyaira mudziyo kunoita kuti pikiseli ipindure nekukurumidza, zvichibatsira zviri nyore kuona zvakanaka pamwero wepamusoro wekuzorodza.

Chechipiri, mabhezeri madiki uye chiyero chepamusoro chechidzitiro nemuviri. Nekugona kutyaira kwakasimba, ma pixel circuits anogona kuderedzwa uku achichengetedza hunhu hwakaenzana hwechiratidziro, achitora nzvimbo shoma yekurongeka uye achigonesa dhizaini yechimiro chidiki. Izvi hazvingogadzirisi chete dhizaini yeindasitiri yemidziyo yekupedzisira, asiwo zvinotsigira ma pixel density yakakwira.

Pamusoro pezvo, tekinoroji iyi inogonesa kuratidzwa kwakasimba pamutengo wakaderera wekugadziridza. Kune standby mode uye mamiriro emifananidzo asingachinji anoda kugara kwenguva refu kwemafuremu, mashandiro emuchina akagadziridzwa anotsigira zviri nani mamiriro epikisheni, kuderedza kupenya kwechiso uye kushanduka-shanduka kwechiedza — zvichiita kuti mifananidzo ionekwe zvakanaka uku uchideredza kushandiswa kwesimba.

Panel Yekutanga Yehukuru Hudiki Yakabatidzwa — Kuwedzera Miganhu Yekushandisa Yetekinoroji Yese YeOxide

Zvichivakira pakubudirira kwekushanda, Visionox yakabudirira kushandisa panel diki-diki ye-all-oxide kekutanga. Kare, zvainge zvakaganhurirwa nekufamba kushoma, ma backplanes e-all-oxide ainyanya kushandiswa pazviratidziro zvepakati nepakati. Kubudirira kwekushanda kwepanel diki kunoratidza kuti nzira iyi yehunyanzvi ikozvino yagadzirira kushandiswa kwepamusoro-soro, zvichitsanangura patsva miganhu yekushandisa ye oxide backplanes.

Kuongororwa kunosimbisa kuti mhinduro yeALD yasangana nezvinodiwa zvekugadzirwa kwehuwandu muzviratidzo zvikuru zvemaitiro: kuchinja kweukobvu hwefirimu kubva kune wafer kuenda kune wafer pasi pe2% uye kufanana kweukobvu hwefirimu mukati me4%. Izvi zvinoratidza kugadzikana kukuru uye kudzokorora mukugadzirwa kwehuwandu, zvichizadzisa zvizere mwero wekuenderana kwekugadzirwa kwepaneru. Parizvino, tekinoroji iyi yakapedza ongororo pamutsetse wekugadzira we4.5G uye inogona kuwedzerwa kune zvigadzirwa zvepamusoro.

Ichitsigira mweya we "kuda, kushinga uye kugona kuita zvinhu zvitsva", Visionox inoshandisa makore anoda kusvika makumi matatu ekuunganidza tekinoroji uye ruzivo rwekuvandudza maindasitiri kugadzirisa matambudziko makuru anotadzisa kufambira mberi kweindasitiri. Tekinoroji iyi yeALD all-oxide inofamba zvakanyanya inoita kuti mashandiro ayo awedzere mukati meimwe oxide system, pasina kuvimba nekubatanidzwa kwezvinhu zvakawanda. Iine mashandiro akakwira, kushanda zvakanaka kwemaitiro uye kugona kukura, yagadzirira kuva nzira yakakosha yehunyanzvi yekuvandudza OLED mune ramangwana uye kupa kukosha kukuru mumakwikwi matsva etekinoroji yekuratidzira.
