Te Mahi a ngā Paewhiri QLED i ngā Pouaka Whakaata Hou
I ngā tau tata nei, kua tere te whanaketanga o te hangarau whakaaturanga pouaka whakaata. I mua ko te LCD me te LED anake ngā kupu whānui i mōhiotia e te tangata, ināianei kua puta ake ngā ingoa hou, pērā i te OLED, Mini-LED, me te QLED. I roto i ēnei kōwhiringa, kua noho te QLED hei tētahi o ngā hangarau e whakamahia whānuitia ana i roto i ngā pouaka whakaata waenga-rahi ki te utu nui nā te mea he kanapa ngā tae, he kanapa teitei, he pakari hoki te mata. Heoi anō, he maha tonu ngā tāngata e whakaaro ana: me pēhea te mahi a ngā panera QLED i roto i ngā pouaka whakaata hou? Ka matapakihia e tēnei tuhinga ngā mātāpono taketake o te QLED, ngā wāhanga e whai wāhi ana, me ōna painga me ōna herenga.
He aha te QLED?
Ko te QLED he tohu mō te Quantum-dot Light Emitting Diode. Ahakoa kei roto i te ingoa te kupu "LED", ehara te QLED i te hangarau whakaaturanga "whaiaro-whakaputa" pērā i te OLED. I te nuinga o te wā, ko te QLED he whanaketanga o te LCD e whakamahi ana i te paparanga ira quantum hei whakapai ake i te kounga tae. Ko te tikanga o tēnei, kei te whakawhirinaki tonu ngā panera QLED ki te rama whakamārama hei whakaputa mārama, ka tukatukahia mā roto i ngā paparanga rerekē i mua i te hanga i tētahi ahua ki runga i te mata.
Nā konei, e kiia ana a QLED he LCD me te whakarei ake i te ira kuantum. I roto i ngā pouaka whakaata hou, ka honoa te QLED ki ngā pūnaha rama hou pērā i te Full Array Local Dimming (FALD) me te Mini-LED, ā, ka hua ake he mahi pai ake i ngā LCD LED tuku iho.
Ngā Wāhanga Matua o te Paewhiri QLED
Hei mārama ki te mahi a te QLED, me titiro tātou ki te whakaritenga o ētahi paparanga nui i roto i te pouaka whakaata, tae atu ki:
1. Rama Whakamuri
2. Pereti Arataki Mārama / Kaiwhakarara (Whakarara Mārama)
3. Papa Ira Kuantum
4. Tātari Tae
5. Paparanga Tioata Wai
6. Tātari Whakapōra (Tātari Whakapōra)
7. Papa TFT (Pūrere Mana Pika)
He mahi motuhake tā ia paparanga, ā, ka mahi tahi ēnei katoa kia mārama, kia koi, kia tika hoki te tae o te ahua e kitea ana e koe i runga i te mata.
Ngā Hipanga mō te Mahi a te Paewhiri QLED
1. Ka whakaputa te rama papamuri i te mārama taketake
Nā te mea he LCD te QLED, ko te pūtake mārama matua i ahu mai i te rama muri. Ko te whakatupuranga hou o ngā pouaka whakaata QLED e whakamahi ana i ngā LED kikorangi hei pūtake mārama, nā te mea ko te whānuitanga kikorangi te mea tino whai hua ki te "whakahohe" i ngā ira matū.
I ētahi momo, ko te rama whakamuri ka taea te:
– Te taha e whakamāramahia ana: Kei te taha o te mata ngā rama LED, ā, e anga ana te mārama ki waenganui. He angiangi ake, he iti ake te utu, engari he iti ake te whakaiti i te kanapa ā-rohe.
– Rama tika / Rārangi Katoa: Kua tohatohahia ngā rama LED kia ōrite ki muri i te panera, kia pai ake ai te whakahaere i te rama.
– Mini-LED: he putanga iti ake o te LED noa, he nui ake te maha, e āhei ai te whakahaere tika ake i te rohe mārama (rohe whakaitiiti).
Mā tēnei wāhanga ka whakatau te kanapa o te whakaaturanga o te pouaka whakaata, inā koa ina mātaki ana i ngā ihirangi HDR.
2. Ka horahia te mārama kia ōrite
Kia kā te rama muri, ka haere te mārama mā roto i te kaiwhakarara me/ranei te pereti arataki mārama. Ka tohatohahia te mārama e tēnei paparanga kia ōrite hei ārai i ngā ira kanapa, pōuri rānei (ngā ira wera). Mā tēnei ka puta he whakaaturanga ōrite ake puta noa i te mata katoa.
3. Ka whakarerekē te paparanga ira matū i te whānuitanga o te māramatanga.
Koinei te mauri o te hangarau QLED. Ko ngā ira kuantum he matūriki nanometer ka taea te tuku mārama i ngā roangaru motuhake ina whakamāramahia. I roto i te QLED, ka pā te mārama kikorangi mai i te papamuri ki te paparanga ira kuantum, ka hurihia ētahi o aua mea hei mārama whero me te kakariki "parakore".
Ngāwari noa iho:
– Ka whakaputahia e ngā LED kikorangi te mārama kikorangi kaha
– Ka "huri" ngā ira matihiko i ētahi o te mārama kikorangi hei whero me te kakariki.
– Ko te hua he huinga pai ake o ngā whānuitanga hei whakaputa i ngā tae whānui, whai kiko hoki.
Nā te mea ka whakaputahia e ngā ira matūriki ngā tae me te whānuitanga whaiti (tino motuhake ake), ka taea e QLED te waihanga i te rōrahi tae pai—arā, he ātaahua tonu te āhua o ngā tae ahakoa ngā taumata kanapa teitei.
4. Ka tātarihia e te tātari tae te tae ki ngā pika-iti RGB.
I muri i te whitinga i te ira matū, ka whiti te mārama mā te tātari tae e wehewehe ana i te mārama kia toru ngā wāhanga matua: whero (R), kakariki (G), me te kikorangi (B). Ko ia pika i runga i te mata he mea hanga mai i ngā pika iti RGB e toru. Ko te kaha whakakotahi o ēnei e toru ka hua mai i te miriona ki te piriona ngā rerekētanga tae.
He rite te mahi a te paparanga tātari tae ki tētahi "kēti tae", hei whakarite kia ōrite te mārama e puta mai ana i ia pika iti ki te tae e hiahiatia ana.
5. Ka whakahaeretia e ngā tioata wai te nui o te mārama e puta ana.
Ko te wāhanga LCD (wai tioata) te kawenga mō te whakahaere i te mārama mō ia pika. Kāore ngā wai tioata e tuku mārama, engari ka huri i te ahunga o te whakapōraruraru mārama. Mā te āwhina o ngā whakapōraruraru i mua me muri, ka taea e ngā wai tioata te whakahaere i te tuku, te ārai rānei i te mārama.
Ina tukuna he tohu hiko:
– Ka rerekē te aronga o ngā tioata wai
– Mā te whakarerekē i te aronga ka whakahaere i te taumata o te mārama ka taea te haere mā roto i ngā pika iti.
– Koinei te mea e hanga ai te ahua mārama-pōuri (rerekētanga) i runga i te mata.
Ka taea e ngā panera QLED o ēnei rā te whakamahi i ngā momo LCD rerekē, pērā i te VA, te IPS rānei, e pā ana ki ngā āhuatanga o te whakaaturanga pērā i te rerekētanga me ngā koki tiro.
6. Ka whakahaere tika te TFT i ia pika
Kei muri i te paparanga tioata wai he TFT (Thin Film Transistor) e whakahaere ana i te ngaohiko mō ia subpixel. He mahi tā te TFT ki te pupuri i te mana pika pumau me te tika, hei ārai i ngā raruraru ahua pērā i te kimo, te ngaro, te kore taurite rānei.
Ko te pai ake o te kounga o te mana TFT me te tukatuka whakaahua, ko te maeneene ake o ngā whakawhiti rōnaki, ā, ko te iti ake o ngā here i runga i ētahi ihirangi.
Te Tūranga o te Whakaiti i te Ataata ā-Rohe i ngā Pouaka Whakaata QLED Hou
Ko tētahi o ngā wero nui o ngā LCD ko ngā taumata pango. Nā te mea he rama whakamārama kei roto, ka puta pea te turuturu o te mārama, ka puta te āhua hina o ngā pango. Hei whakatika i tēnei, he maha ngā wā ka whakamahia e ngā pouaka whakaata QLED hou te whakaiti i te mārama o te rohe: ka taea te whakaiti, te whakaweto rānei i ngā wāhi motuhake o te rama whakamārama kia rite ki ngā hiahia o te ahua.
Mena kei te whakaatu i tētahi tirohanga pō me ngā rama iti:
– Kua whakapōuritia ngā rohe rama whakamuri i ngā wāhi pōuri
– Ka noho mārama tonu te rohe i te wāhi kanapa
– Ka nui ake te rerekētanga, ā, ka kitea ake ngā taipitopito
Mā te Mini-LED ka nui ake te whai huatanga o te whakaitiiti ā-rohe nā te mea he maha atu ngā rohe, nō reira ka taea hoki te whakaiti i te pānga "halo" (te pua) huri noa i ngā mea kanapa.
Ngā Painga o te QLED i runga i ngā Pouaka Whakaata Hou
1. Te kanapa teitei
He pai mō ngā rūma kanapa me ngā ihirangi HDR, nā te mea ka taea e ia te whakaputa i ngā whakamārama kanapa, pakari.
2. Ngā tae momona ake, ā, pumau ake
Ka whakanui ake ngā ira matū i te parakore o te tae, tae atu ki te kanapa teitei.
3. He iti te mōrearea o te tahunga
Nā te mea kāore e tukuna aunoatia pērā i te OLED, he haumaru ake te QLED mō ngā whakaaturanga pūmau mō te wā roa (ngā waitohu pouaka whakaata, ngā HUD kēmu).
4. He rerekē ake ngā utu
He nui ngā kōwhiringa QLED puta noa i te whānuitanga o ngā utu, inā koa ka whakaritea ki ngā OLED utu nui.
Ngā Herenga QLED Me Mōhio Koe
1. Kāore ngā pango i te "hohonu" pērā i ngā OLED
Nā te mea kei te mau tonu te rama whakamārama, he uaua ki te whakatutuki i te mangu tuturu, ahakoa he āwhina te whakaiti i te kanapa o te wāhi.
2. Te pūmanawa puāwaitanga
I ngā tirohanga tino rerekē, ka taea e ngā mea kanapa te "toto" te mārama ki runga i te papamuri pouri, ina koa he iti te rohe.
3. Ko te koki tirohanga e whakawhirinaki ana ki te momo panera
He nui te rerekētanga o ngā koki tirohanga o ngā panera VA engari he whaiti ake; ko te IPS te ritenga kē.
Whakamutunga
Ko ngā panera QLED o ngā pouaka whakaata hou ka mahi mā te whakakotahi i te hangarau LCD me te paparanga ira-kuantum e whakarei ake ana i te whānuitanga tae. Ko te mārama mai i te papamuri—he maha ngā wā he LED kikorangi—ka tukatukahia e ngā ira-kuantum hei whakaputa i ngā tae whero me te kakariki parakore, kātahi ka whakahaerehia e ngā tioata wai me te pūnaha transistor TFT hei hanga i te ahua. I roto i ngā tauira hou, ka whakarei ake te QLED mā te whakakotahi me ngā hangarau whakaitiiti ā-rohe matatau ake pēnei i te FALD me te Mini-LED, ka hua ake he pai ake te rerekētanga me te mahi HDR.
Mō ngā kaiwhakamahi e hiahia ana ki tētahi pouaka whakaata kanapa, kanapa hoki, ā, he roa te ora mō te whakamahi i ia rā, mō te petipeti hoki, he kōwhiringa ātaahua te QLED. Heoi, ki te mea ko ngā pango tino pai me te rerekētanga tino nui ōu kaupapa matua, ko te hangarau OLED tonu te kōwhiringa pai rawa atu. Hei whakamutunga, mā te mārama ki te mahi a te QLED ka āwhina i a tātou ki te whiriwhiri i te pouaka whakaata tika mō ō tātou hiahia me ngā āhuatanga o te rūma.
Ki te hiahia koe, ka taea e au te tāpiri i tētahi ripanga e whakataurite ana i te QLED me te OLED me te Mini-LED, ka taea rānei e au te tuku tohutohu mō ngā tawhā nui ina whiriwhiri ana i tētahi pouaka whakaata QLED (te kanapa o ngā nits, te maha o ngā rohe whakaitiiti, te momo panera VA/IPS, me te tautoko HDR).
