P0.6-P0.3: Hoʻomaikaʻi i ʻelua ala ʻenehana nui
No nā noi P0.6-P0.3, kālele nui ʻo Lattice i ka Thin Film LED, kahi ʻenehana kiʻi ʻoniʻoni ʻoniʻoni me ka ʻole o ka substrate, e uhi ana i ke ʻano kū pololei a me ke ʻano o ka flip chip.ʻO ka LED kiʻiʻoniʻoni lahilahi e pili ana i kahi puʻupuʻu LED kiʻiʻoniʻoni lahilahi i wehe ʻia mai ka substrate.Ma hope o ka wehe ʻia ʻana o ka substrate, hiki ke hoʻopaʻa ʻia kahi substrate hou a i ʻole hiki ke hana ʻia kahi ʻano kū pono me ka ʻole o ka hoʻopaʻa ʻana i ka substrate.Kapa ʻia ʻo Vertical thin film, a i ʻole VTF no ka pōkole.I ka manawa like, hiki ke hana ʻia i loko o kahi ʻāpana flip-chip me ka ʻole o ka hoʻopaʻa ʻana i ka substrate, i kapa ʻia ʻo thin film flip chip, a i ʻole TFFC no ka pōkole.
Ke ala ʻenehana 1: VTF/TFFC chip + quantum dot ʻulaʻula kukui (QD + kukui polū InGaN LED)
Ma lalo o ka liʻiliʻi liʻiliʻi loa, ʻo ka AlGaInP ʻulaʻula LED maʻamau he mau waiwai mechanical maikaʻi ʻole ma hope o ka wehe ʻia ʻana o ka substrate, a he maʻalahi loa ka haki ʻana i ka wā o ka hoʻololi ʻana, e paʻakikī ai ka hoʻokō ʻana i ka hana nui ma hope.No laila, hoʻokahi ka hopena o ka hoʻohana ʻana i ka paʻi ʻana, ka pīpī ʻana, ka paʻi ʻana a me nā ʻenehana ʻē aʻe e kau i nā kiko quantum ma ka ʻili o nā LED polū GaN e loaʻa ai nā LED ʻulaʻula.
Alanui ʻenehana 2: Hoʻohana ʻia nā LED InGaN i nā kala RGB āpau
Ma muli o ka lawa ʻole o ka ikaika mechanical o ke kukui ʻulaʻula quaternary i kēia manawa ma hope o ka wehe ʻana i ka substrate, paʻakikī ke hoʻokō i ka hana hana ma hope.ʻO kahi hopena ʻē aʻe ʻo nā kala ʻekolu o RGB he mau InGaN LED āpau, a ma ka manawa like e ʻike i ka hui ʻana o ka epitaxy a me ka hana chip.Wahi a nā moʻolelo, ua hoʻomaka ʻo Jigneng i ka noiʻi a me ka hoʻomohala ʻana o ke kukui ʻulaʻula gallium nitride ma nā substrates silika, a ua hana ʻia kekahi mau mea i hana ʻia i loko o nā kukui uila ʻulaʻula InGaN, e hiki ai i kēia ʻenehana.
He mea pono ke hoʻomaopopo ʻia, ma ka hoʻohālikelike ʻana i nā pono a me nā pōʻino o TFFC, FC, a me Micro chips e pili ana i ka substrate, ka hoʻokaʻawale ʻana i ka puʻupuʻu, ka maikaʻi o ka luminous, a me ka hoʻoili nui ʻana, ua hiki ʻo Lattice i ka hopena: me ka hoʻohana ʻana i ke ala ʻenehana a Micro a me Lattice's ʻO ka hui pū ʻana o Hiki i nā ʻāpana liʻiliʻi ke hōʻemi nui i nā kumukūʻai chip me ka hōʻemi ʻana i ka pilikia ʻenehana.ʻO ia hoʻi, ʻo 4K a me 8K Mini ultra-high-definition LED nā huahana pale nui e manaʻo ʻia e komo i nā tausani o nā hale.
I kēia manawa, ʻo 4K a me 8K Mini ultra-high-definition hōʻike i nā pale nui i hiki ʻole ke hoʻokuʻu ʻia e ka ʻenehana 5G, a ua loaʻa i nā chips mini LED kūpaʻa silicon substrate ka manawa e lilo i kumu kumu kumu kumu kūʻai maikaʻi loa.
