Ina tata nei, ka whakaputahia e te roopu rangahau a BOE he pepa i tapaina ko Novel Package Design Enhances Optical Efficiency of Micro LED Displays i roto i te retaata Whakaaturanga Korero.

Whakaaturanga Micro LED Te Hanganga Moroiti Tukanga Hoahoa Hoahoa (Putake Whakaahua: Whakaaturanga Korero)

Ka whakaarohia e te rangahau he kaupapa whakahiato moroiti Micro LED, e tutuki pai ana nga wero hangarau a te ahumahi penei i te kaha o te tukunga tahataha o nga maramara LED moroiti, te iti o te kaha o te whakamahi hiko marama, me te neke tae.

E ai ki te korero i te mea ka heke te rahi o te pika ki raro iho i te 50μm, ka piki ake te waahi o te taha taha maramara, ka piki ake te tukunga taha taha me te whakaheke i te whakaputanga o runga o nga Micro LED. Na tenei ka ngaro te kanapa me te rereke o te tae, ka aukati i te tono a nga Micro LED i roto i nga ahuatanga whakaatu tino tika.

Hei whakatika i tenei take, i hangaia e te roopu rangahau a BOE he hanganga taapi hiato e mau ana i te whakapiringa maramara-whakaaro-nui-a-ringa, te kapia whakaata teitei ma, nga huinga microlens, me te tauira matrix pango (BM).

Na roto i te whakauru i tetahi paparanga taupū whakarorohiko i runga i nga maramara Micro LED, i pai ake te whakapai ake a nga kairangahau i te koki putanga o te marama mai i te tihi o te maramara, me te whakanui ake i te koki arohaehae mai i te 25 nga nekehanga ki te teitei o te 65.9 nga nekehanga me te tino whakarei ake i te pai o te tango marama.

I tenei wa, ko te kapia whakaata ma te hanga i te hanganga trapezoidal isosceles i waenga i nga maramara, ka taea te whakakoi me te titaritari i te marama, ka piki ake te kanapa i te koki tirohanga 0° tata ki te 27%. I tua atu, ko te tikanga plasma hei tango i nga toenga taapiri ka whakarite kia kore e arai te marama.

Mo te whakahaere marama, i whakamahia e te roopu te hangarau nanoimprint lithography ki te hanga i nga huinga microlens tino tika, kia pai te whakakotahitanga o te marama i roto i te ±60°.

Ko nga hua whaihanga e whakaatu ana i te wa e 0.03 te piko o te arotahi me te 1.85 te taupū whakaata, ka piki ake te kaha o te rama ma te 53%. I tua atu, i whakaurua e te rangahau he matrix pango kua tauira ki roto i te paparanga karaihe takai, he pai te whakaiti i te whakaata ki te iti iho i te 2% me te whakatutuki i te ōwehenga rereke nui atu i te 20,000:1, ka tino whakapai ake te kounga whakaaturanga.

I kii te roopu rangahau a BOE, ehara i te mea ka tutuki noa i tenei kaupapa nga mahi totika mo te whai kiko me te riterite engari ka whai whakaaro ano ki te pono o te kete. Ko te whakakotahitanga o te uhi karaihe me te paparanga OCA (Optically Clear Adhesive) ka whakarei ake i nga taonga parewai, anti-oxidation, me te kakahu-aukati, e whakarato ana i te huarahi pono mo te tono hanga papatipu o Micro LEDs i roto i nga mara penei i nga whakaaturanga motuka, AR / VR pane, me nga taputapu kakahu.

Ehara i te mea kua tutuki noa i te BOE nga hua rangahau Micro LED hou engari kei te haere tonu ki te whakatairanga i te whanaketanga o te hangarau whakaatu tika a Mini/Micro LED me nga tono.
