Micro LED Fasahar nuni ta yi nasara a yaƙin hanyar nuni mai haske

A WAIC na shekarar 2024, Lenovo ta kawo kwamfutar tafi-da-gidanka ta farko mai haske a duniya, wacce ke amfani da allon Micro LED mai haske mai inci 17. Au ta gabatar da babban allon 3D Micro LED mai haske mai inci 30 a duniya a Touch Taiwan 2024. A baya, AU ta kuma nuna allon Micro LED mai haske mai inci 60 don yanayi daban-daban a ISE 2024. A CES 2024, Samsung ta nuna allon MicroLED na farko mai haske. A CITE 2024, Tianma Microelectronics ta nuna allon Micro LED mai haske mai inci 8.07, PPI har zuwa 167, watsawa har zuwa 55%, haske mai cikakken allo >1500nits...

Ba cikakken kididdiga ba ne, daga shekarar 2023 zuwa yanzu, kamfanoni sama da 15 a duniya sun nuna nau'ikan Nunin haske na Micro LEDKasuwar ta ƙunshi fannoni daban-daban kamar abin hawa, nunin kasuwanci, fasahar zamani da amfani da kwamfuta, 3D, duka injunan da ke da haske duk-cikin-ɗaya, ƙananan nunin da ke da haske, da samfuran na'urorin nunin injiniya waɗanda suka dace da buƙatun manyan allo na 1*N. Ana iya cewa ƙirƙira da ƙirƙirar Micro LED Transparent kasuwa tana shiga cikakken matakin fure.

To, a cikin fasahohin nuni daban-daban, me yasa Micro LED zai iya jawo ƙarin "ƙarfin ƙirƙira na nuni mai haske"? Amsar ita ce duka fasahar nunin LCD da OLED suna da nasu kurakuran da ba su dace da bayyanawa ba.

Da farko dai, na'urar nuni ta fasahar LCD tana buƙatar hasken baya don samar da haske. LCD mai haske dole ne ya zama nau'in gefen hasken baya.

Bugu da ƙari, tsarin hasken baya na LCD yana da tasirin haske akan matsayin haske na waɗanda ba pixels ba akan allon haske na LCD. Wannan yana sa bambanci tsakanin pixels na allon haske na LCD da ɓangaren da ba shi da haske na nuni ya zama "babba sosai", wanda ke ƙara shafar tasirin ingancin hoto.

Na biyu, allon haske na fasahar OLED a halin yanzu yana samuwa a cikin samfura da yawa, tare da matsakaicin murfin inci 77, kuma ana iya tsara shi don tallafawa aikace-aikacen haɗakarwa. Duk da haka, KAI NEFasahar nuni koyaushe ba ta da kyau a aikin haske. Misali, tsarin OLED mai layuka biyu da ake amfani da shi a allon IT shine don inganta matakin haske. Kuma nuni mai haske, saboda ana amfani da babban yanki na allo azaman tsari mai haske, maimakon tsarin hoton OLED, daidaito tsakanin haske da haske shima yana fuskantar matsaloli.

Za a iya cewa babban cikas ga aikace-aikacen bayyana haske na LCD da OLED shine "yadda ake inganta haske". Dangane da wannan, Micro LED yana da fa'ida ta halitta. Micro LED da aka yi amfani da shi a kan allo mai haske zai iya samun haske sama da nits 1000 cikin sauƙi. Wannan ya faru ne saboda babban matakin da kuma ci gaba da inganta ingancin haske na fasahar LED.

Nunin haske na Micro LED, haske da haske sosai

Domin fa'idodin nunin Micro LED bisa ga ka'idar bayyana gaskiya, masana'antar ta yi imanin cewa ban da ingantaccen haske da kuma babban hasken LED ɗin kanta, ƙaramin girman lu'ulu'u na Micro LED shi ma babban fa'ida ne.

Wato, tsarin pixel na allon LCD da OLED masu haske, domin a kiyaye "haske mai kyau", tsarin pixel yana buƙatar ya haɗu da wani yanki. A halin yanzu, babban allon OLED mai haske, pixel da sauran tsare-tsare marasa haske sun mamaye rabin yankin panel gaba ɗaya, wanda shine mabuɗin watsa shi ba za a iya inganta shi sosai ba.

Sabanin haka, ƙananan lu'ulu'u na LED kusan haske ne na gaske. Tare da girman ƙasa da microns 50, rabon yankinsa akan allon zai iya raguwa zuwa ƙasa da kashi 95% - wato, isasshen yanki kyauta ne don samar da sarari don wayoyi na pixel da tsarin haske. A lokaci guda, babban haske na LED yana tarawa cikin hasken haske, wanda ya fi dacewa don samar da babban bambanci tsakanin wurin pixel da ɓangaren haske, kuma jikewar launi da kuma fahimtar hoto mai girma uku sun fi kyau.

Ko da kuwa, amfani da ƙananan ƙwayoyin pixel na Nunin Micro LED, AU ta ƙirƙiro samfurin nunin ido na 3D mai launuka biyu tare da tsarin pixel na Micro LED mai launuka biyu. Masana'antar ta yi imanin cewa nan gaba ma za ta iya amfani da ƙananan pixels na Micro LED don yin allon pixel na Micro LED mai launuka da yawa don cimma ingantattun samfuran nuni na 3D na ido da ma na stereoscopic.

Baya ga warware sabanin haske da kuma ikon amfani da hasken, ƙaramin girman Micro LED da kuma ingantaccen haske mai yawa na iya taimakawa wajen magance matsalar. Micro LED kuma yana da wasu fa'idodi a cikin inganta haske da tasirin bambanci na nuni mai haske. Domin, idan aka kwatanta da lu'ulu'u na ruwa da OLED, Micro LED kanta ba wai kawai yana nuna haske mafi girma ba; Bugu da ƙari, yana da sauƙi a kula da daidaito da daidaito a cikin kewayon haske mai faɗi, wanda zai iya samar da sarari mai faɗi don ƙirar allo mai haske don daidaita hasken Micro LED bisa ga hasken yanayi.

Ba shakka, a matsayin fasahar fitar da haske, Micro LED ba zai iya zama allo shi kaɗai ba - yana buƙatar substrate. A wannan fannin, Micro LED ma yana da fa'ida. A gefe guda, Micro LED na iya amfani da fasahar substrate gilashin AM TFT mai girma akan LCD da OLED; A gefe guda kuma, yana iya amfani da samfuran substrate gilashin PM waɗanda aka ƙera musamman don aikace-aikacen nunin Micro LED. Na ƙarshen yana da amfani don rage farashin samfuran nunin Micro LED akan manyan nuni.

Duk da haka, duk da cewa Micro LED yana da mafi kyawun "halayen fasaha" na ka'ida don allon mai haske, masana'antar har yanzu tana cewa allon mai haske na Micro LED yana buƙatar ingantawa dangane da balaga ta fasaha, aminci da farashi idan tana son zama samfuri na duniya baki ɗaya.

Tsarin da aka haɗa don toshe ƙulle na ƙarshe na nuni mai haske na Micro LED

Duk wani samfuri da ya shigo kasuwa dole ne ya fara fuskantar gwajin gasa a farashi. A halin yanzu, allon haske na Micro LED har yanzu bai gamsar da wannan ba. Babban dalilin shine babban tsarin canja wurin ba shi da girma kuma ba shi da tabbas.

Nunin Micro LED wani ƙaramin ƙwayar crystal ne da aka haɗa shi da kuma haɗa shi da allon tuƙi. Ga samfuran nunin launi na 2K, ana buƙatar canja wurin ƙwayoyin crystal sama da miliyan 6.22, a sanya su a wuri, a haɗa su, a gyara su.
