Te Tukanga Hanga Whakaaturanga QHD mō ngā Waea Atamai
Kua noho ngā whakaaturanga QHD (Quad High Definition) hei āhuatanga nui mō ngā waea atamai waenga-rahi ki ngā waea atamai matua. Ko te kupu QHD i roto i ngā waea atamai e pā ana ki te taumira tata ki te 2560 × 1440 pika (he momo rānei me te ōwehenga āhua whānui pērā i te 3200 × 1440), e whakarato ana i te koi me te taipitopito whakamāramatanga teitei mō ngā tuhinga, ngā whakaahua, ngā ataata, me ngā wheako petipeti. Heoi, kei muri i taua kounga ahua koi kei reira he tukanga hanga matatini, tino tika e uru ana ki te hangarau rauemi matatau. Ka tūhuratia e tēnei tuhinga ngā wāhanga matua o te tukanga hanga whakaaturanga QHD, mai i te hoahoa ki te whakamātautau whakamutunga.
1. Ngā Whakatakotoranga o te Paewhiri me te Hoahoa Hanganga
Ka tīmata te tukanga hanga i mua noa atu i te hanga a te wheketere i ngā panera. Ka whakawhanakehia e te tīma R&D ngā whakatakotoranga: te rahi o te mata (hei tauira, 6,5 inihi), te momo panera (OLED/AMOLED, LCD rānei), te tere whakahou (60 Hz, 120 Hz, tae atu ki te 144 Hz), te kanapa teitei, te whai hua o te mana, te tautoko HDR, me ngā whāinga whakaputa tae (DCI-P3, sRGB) me te tika (Delta E).
Ka whakatauhia hoki e tēnei wāhanga te hoahoanga pika (hei tauira, te rārangi RGB, te Pentile rānei i runga i te OLED), te hoahoa ōwehenga whakatuwheratanga (te ōwehenga o ngā wāhi e tukuna ana te mārama), me te hanganga paparanga, e pā ana ki te tuku mārama, te whakapaunga hiko, me te roa. Mō te QHD, ko te wero kia nui te kiato pika me te kore e whakaiti i te kanapa me te whai huatanga.
2. Te Whakarite Papa: Te Tūāpapa Papa
Ko te papa te "tūāpapa" e hangaia ai te hanganga whakaaturanga katoa. Ko ngā panera OLED waea atamai hou e whakamahi ana i te karāhe tino angiangi, i ngā papa polymer ngāwari rānei (hei tauira, polyimide) hei tuku i te mata kia piko, kia angiangi ake rānei ngā anga. Mō ngā LCD, ko te papa he karāhe te nuinga.
Kei roto i te wāhanga whakarite te horoi matū, te whakamaroke, me te tirotiro i te mata. Ahakoa ngā matūriki moroiti, ngā poke iti rānei, ka taea te whakaputa pika mate, te turuturu mārama, te koretake rānei o te tae. Nō reira, ka mahia te tukanga i roto i tētahi rūma ma, tino ma.
3. Tukanga Papamuri TFT: "Porowhita" Whakahaere Pika
E hiahiatia ana e te OLED me te LCD he paparanga TFT (Thin Film Transistor) hei papa tuara, he whatunga o ngā transistors e whakahaere ana i ia pika. Koinei tētahi o ngā wāhanga tino uaua nā te mea ko te taumira QHD te tikanga he nui rawa ngā pika; he iti ngā pika o ia pika me whakahaere, ka nui ake te uaua o te ara iahiko.
Ko ngā mahi whānui mō te hanga i tētahi TFT ko:
1. Te whakatakoto kiriata angiangi: Ka whakatakotoria te rauemi hiko-haurua (hei tauira, LTPS—Low-Temperature Polycrystalline Silicon, LTPO rānei—Low-Temperature Polycrystalline Oxide) ki runga i tētahi papa.
2. Whakaahua-ā-ringa: Ka tāia te tauira ara iahiko transistor mā te whakamahi i te photoresist me te kōpare. Mā tēnei tukanga ka whakatauhia te tika o te rahi o te āhuatanga, tae atu ki ngā ara whakarewa me te horahanga transistor.
3. Te whakairo me te horoi: Ka tangohia ngā wāhanga kāore e hiahiatia mā te tukanga matū/plasma.
4. Whakamahana: Te whakamahana whakahaere hei whakapai ake i te hanganga tioata me te whakanui ake i te nekenekehanga irahiko.
Kei te piki haere te rongonui o te hangarau LTPO i roto i ngā whakaaturanga QHD me ngā tere whakahou urutau nā te mea he nui ake te whai huatanga o te mana. Heoi, he uaua ake te tukanga hanga nā te mea ka whakakotahi i ngā āhuatanga o te LTPS me te waikura.
4. Te Hanganga o te Papa Tukunga (OLED) te Papa Tioata Wai rānei (LCD)
I tēnei wā, ka rerekē paku te rere o te tukanga i runga i te momo o te panera.
a) Mena he QHD OLED/AMOLED
Me whai paparanga rauropi e whakaputa ana i te māramatanga ngā panera OLED. Ka hangaia tēnei paparanga mā te whakamahi i ngā tikanga pēnei i te mimiti wera korehau (VTE) mā te whakamahi i te kopare whakarewa pai (FMM), i ētahi atu tikanga pēnei i te tā waituhi waituhi i roto i ētahi huarahi whakaputa.
– Te Kōpare Whakarewa Pai (FMM): Ka whakamahia he kōpare tino angiangi hei whakatakoto i ngā rauemi RGB waro ki ngā wāhi iti-pika tino tika. Mō ngā taumira teitei pēnei i te QHD, he mea nui te tika o te whakarārangi. Ka taea e te kōpare te piko, te whakapē rānei i te āhua nā te wera, me te whakahaere kaha i te ngaohiko me te pāmahana.
– Ngā paparanga katote me te anote: Ko ngā irahiko mārama (hei tauira, ITO—Indium Tin Oxide) me ētahi paparanga whakarewa hei hanga i te hanganga o te diode waro.
I muri i te whakatakotoranga, me tiaki ngā panera mai i te makuku me te hāora, nā te mea he tino tairongo ngā rauemi rauropi.
b) Mena he QHD LCD
Kāore ngā LCD e tuku mārama i a rātou anō, ā, me whai rama whakamārama. Ko te hanganga matua o ēnei ko:
– Papa whakarārangi hei whakarite i te whakatakotoranga o ngā tioata wai
– Ngā mea whakawātea hei whakarite i te tawhiti ōrite i waenga i te karāhe
– Te whakakī i te karaihe wai mā te tukanga whakakī korehau
– He hiri hei hiri i ngā panera
I roto i ngā LCD QHD, ko ngā wero matua ko te ōritetanga o te tohatoha o te tioata wai me te whakahaere matotoru hei karo i ngā rerekētanga rerekētanga, i te turuturu rānei o te mārama.
5. Tātari Tae me te Polarizer (Ina koa i runga i te LCD)
I roto i ngā LCD, he paparanga nui ngā tātari tae mō te whakaputa i ngā tae whero, kakariki, me te kikorangi. Ka hangaia ēnei tātari mā te tukanga whakaahua-ā-ringa anō mō ia tae. Muri iho, ka tāutahia he pōrari hei whakahaere i te pōraritanga o te mārama, kia taea ai e te LCD te "ārai" te "tuku" rānei i te mārama mai i te papamuri.
I roto i ngā OLED, ka taea hoki te whakamahi i ngā whakapōrari (hei tauira, hei whakaiti i ngā whakaata), engari ko ētahi hoahoa hou e whakamahi ana i ētahi atu tikanga pērā i ngā paninga ārai-whakaata (AR) me ngā tikanga whakapōrari porowhita kua arotauhia.
6. Te Whakakī: Ka Tiaki i te Paewhiri mai i te Taiao
Ko te whakakāpōtanga he tukanga paninga tiaki, he mea tino nui mō ngā OLED. E rua ngā huarahi noa:
– Te whakakākahu karāhe (he pakari ake, he mea noa i roto i ētahi hoahoa)
– Te Whakakī Kiriata Angiangi (TFE) (he mea noa i roto i ngā OLED ngāwari), arā, he maha ngā paparanga angiangi kore-oraora kua whakaritea kia maha ngā wā hei ārai i te urunga o te wai/hāora.
Me tino piri te taupoki; mā ngā turuturu iti ka puta he "ira pango" ka whānui haere i te roanga o te wā nā te pirau o te rauemi rauropi.
7. Te Whakarerekētanga: Te Whakakotahi i ngā Paewhiri ki roto i tētahi Paewhiri Mata
Kia oti te panera turanga, ka neke te tukanga ki te wāhanga kōwae. I konei, ka honoa te panera ki ngā wāhanga tautoko:
– Karāhe taupoki (hei tauira, Gorilla Glass)
– Pūoko pā (i roto i te pūtau, i runga i te pūtau, motuhake rānei)
– Piripiri mārama whatu (OCA) mō te whakapiripiri kore-mirumiru
– Te taraiwa IC me te taura whakapiko (FPC) hei hono atu ki te papahoahoa
He taahiraa nui te whakarārangi: he nui te pānga o te puehu, o ngā mirumiru rānei ki te kounga. Mō ngā mata QHD, ka kitea mārama ngā hapa iti nā te mea he koi rawa te mata, ā, ka māmā ake te kite i ngā hapa.
8. Te Whakatikatika Tae me ngā Tautuhinga Tawhā Whatu
Ko te tikanga, ko ngā panera QHD he whakaatu i ngā tae tika, ōrite hoki. Nā te mea ka rerekē ngā āhuatanga o ngā panera i waenga i ngā rerekētanga hanga, ka:
– Te whakatikatika ira mā (hei tauira, D65)
– Te whakarārangitanga o te gamma
– Te ine i te kapinga o te wāhi tae (sRGB/DCI-P3)
– Te whakatikatika i te ōritetanga o te kanapa
Ka taea te tiaki i tēnei whakatikatika hei kōtaha ki te mahara o te papatohu, ka taea rānei te utu mā te pūmanawa i runga i te pūrere.
9. Mana Kounga: Whakamātautau Tino Kaha hei Pupuri i te Tūturutanga
I mua i te tukunga o ngā panera ki te huihuinga waea atamai, ka whakahaerehia he raupapa whakamātautau:
– Tirotiro pika: kitea ngā pika mate/piri, ngā pika iti-pika rānei kāore i te ōrite
– Whakamātautau ōritetanga: e tirotiro ana i te ōritetanga o te tae me te kanapa
– Whakamātautau tahunga-roto (OLED anake): te whakahaere i te panera i raro i ētahi tikanga hei whakau i ngā āhuatanga tuatahi me te kite wawe i ngā raruraru pea.
– Whakamātautau pā: kia maeneene, kia tika hoki te urupare pā
– Whakamātautau pono: whakamātautau pāmahana/haumākū, whakamātautau maturuturunga o te kōwae, huringa wera, me te whakamātautau koroheketanga
Ko ngā panera kāore e tutuki i ngā whakaritenga ka whakarōpūtia anō (ka tangohia i roto i te ipu para) ka whakakahoretia rānei.
10. Ngā Wero Nui i roto i te Hanga Whakaaturanga QHD
Mā te whakanui ake i te taumira ki te QHD ka tāpirihia he taumahatanga ki ngā āhuatanga maha o te whakaputa. Ko te nui o te kiato pika e hiahiatia ana:
– He whakaahua tika ake
– He ārai me te whakarārangi piripono (OLED me te FMM anake)
– Ngā taraiwa IC me ngā ara tohu e kaha ana ki te whakahaere raraunga nui ake
– Whakahaerehia te whakapaunga hiko kia pai ai te whakamahi i te pākahiko
Hei tāpiritanga, he maha ngā wā ka honoa te QHD me ngā tere whakahou teitei, e hiahia ana ki ngā hangarau papamuri matatau ake (hei tauira, LTPO) me te arotautanga whānui i waenga i te taputapu me te pūmanawa.
Te Katinga
Ko te tukanga hanga mō ngā whakaaturanga waea atamai QHD he ranunga o te pūtaiao rauemi, te hangarau haurua-ira, me te mana kounga taumata-teitei. Mai i te hanganga uaua o te papa tuara TFT, ki te whakatakotoranga o te paparanga tuku, te karaihe wai rānei, ki te whakakī me te whakatikatika tae, me mahi ia taahiraa me te tino tika. Ko te mutunga he whakaaturanga koi, he kanapa, he arotau hoki—he wāhanga e kitea pinepine ana i roto i te wheako kaiwhakamahi waea atamai hou.
Ki te hiahia koe, ka taea e au te whakarerekē i tēnei tuhinga kia hangarau ake (hei tauira, te matapaki i te LTPO vs LTPS, te hanganga o te Pentile subpixel, ngā taipitopito taahiraa photolithography rānei), kia rongonui ake rānei, kia ngāwari ake hoki te mārama mō te kaipānui whānui.
