He aha te mea rama arahina? momo o te rama

Ngä o hanga pouaka whakaata whakamōhio kaiwhakamahi wā ki hangarau hou e whakapai ake i te whakapakoko kounga o te tuku. Huarahi ki te houhanga rongo o nga mata TV me āhuatanga arahina kua roa taukei nga kamupene nui rawa. Aita i maoro a'e, haere hoki te puna o te mura kanapa, me te ngohengohe i runga i ngā whakaaturanga pūkoro. Arotake i te hua o te whakatau taua taea me ngā kaiwhakamahi o te rama tuku iho e hāngai ana i runga i LED, engari, o te akoranga, backlight nga kanohi tino ātaahua arahina-mata pouaka whakaata. Ko te atu na te mea kīnaki reira me ētahi atu tahuri nui-tech whakamahia mo te whanaketanga o tenei tikanga.

Ko te pūrere rama

I roto i te hanganga o ngā kōwae ki te whakatinana i te backlight e whakamahia arahina-huānga e ai ngā o ma huānga LED tae rerekē luminescence ranei, pērā i RGB. hangaia ana te poari te ki te pīkau i te kopu āta hangaia ki te whakauru ki roto ki te pūrere kawe tauira motuhake. Tikanga, kua whakaritea te taha maui o te tūhono poari, whakarato tetahi o nei te māramatanga mana arahina, ia e hangaia ētahi ki te whakahaere i tona whirihoranga whakahaere. Ano hoki kōwae arahina whakamahi i te taraiwa motuhake, e pā ana te mahi o nei ki te kaiwhakahaere.

I roto i te puka oti arahina Unuhia ngā o te raupapa o rama iti nei e hono i roto i ngā rōpū o te 3 mongamonga. Pono, e kore e kaiwhakanao tūtohu pokanoa ki te pūrere taua rïpene, engari kia pae tino poroa ai ranei, hei kōrero, mahi pūrere roa ki te hiahiatia. Ano, whakarato te kōwae arahina-backlight mata te kaha ki te whakatika i te wherikotanga, pupuritia tīmata maeneene me te rawa ki te tiaki ki ngaohiko.

Classification momo tautuhinga backlight

E rua ngā huarahi ki te whakauru i māramatanga arahina - hāngai, me te mutunga. titau te whirihoranga tuatahi e ka kia kei te ngohi i muri te rōpū karaihe wai. taea te kōwhiringa tuarua ki a koutou te hanga rawa kikokore awhi mata me te huaina Edge-arahina. I roto i tenei take, te whakanohonga o rīpene a tawhio noa te paenga o te taha roto o te whakaaturanga. Ko te kupu kawea te tohatoha ōrite o te LED e roto e te tikanga o te rōpū tikanga e te muri te LCD - te tikanga tenei momo o te backlight-mata arahina te whakamahia i roto i te whanaketanga o ngā pūrere pūkoro. Piri backlight tika tohu hua kounga o luminescence, tutuki nei e te maha nui o LED me te mohimohiraa rohe ki te whakaiti i koputaputa tae.

Taupānga o te pūwhakamārama arahina

Ka taea e te kiritaki toharite kitea tenei hangarau i roto i te tauira o Sony pouaka whakaata, LG ko Samsung, me te hua Kodak me Nokia. O te akoranga, kua riro nga LED whānui, engari ko te reira i roto i te tauira o enei kaihanga kua kitea huringa kounga i roto i te ahunga o te whakapai ake i te mau huru kiritaki o tenei whakatau. Ko tētahi o nga raruraru matua e fehangahangai e kaihoahoa ko ki te tautoko i te mahi mata ki āhuatanga tino arotau i roto i ngā o te rā tika. Ano, kua tata ake te arahina arahina-backlight i roto i ngā o te whakanui ake i te taa. Ki te kōrero tatou e pā ana ki te ahunga whakamua i roto i te ahunga o te hanganga mata, ka i reira e nui ngä i te matotoru o te awhi, me te hototahi ki te mata whānui. Engari noho raru kāore. e kore e taea e ki tino whakawhanake ratou kaha i roto i te tukanga o te whakaatu i ngā mōhiohio LED. Heoi, e kore tenei i ārai te arahina-hangarau hiki CCFL-rama me te whakataetae ki te whakatupuranga hou o ngā mata wē.

pānga te tauturu

Kōwae i runga i te p marama-emitting i te rota o ngā kaha ki te whakarato i ngā pānga rerekē. I tenei wā o te whanaketanga o ngā kaiwhakanao hangarau kaha e te whakamahi i rua rongoā stereoscopic. E whakarato ana te tuatahi te ine koki o te fluxes radiation ki te tautoko o te pānga ttara. Ko te kaiwhakamahi e taea te kite i te pānga i roto i te akoranga o te mātakitaki mā te mōhiti ranei kahore a ratou, e ko, i roto i te aratau holography. Te pānga tuarua ngā te displacement o te rere luminous e tuku rama arahina-whakaatu ki te ara tomu'a i roto i te papa karaihe wai. Ka taea te ngā Whakamahia o tenei hangarau ki 2D-a 3D-hōputu muri te faafariuraa e tika ana transcoding ranei. Heoi, e kore e pā ana haere i te huinga taea ki whakapakoko e toru-ahu i te backlights arahina e pai.

Hototahi ki te hangarau 3D

E kore e taea e tatou te mea e te mata ki arahina-backlit, i reira he raruraru nui o te pāhekoheko ki te hōputu 3D, engari mo te perception ikeiketanga o te pūtirotiro taua he "pikitia" rapua e mōhiti motuhake. Ko tētahi o nga wāhi tino whaihua o tenei whanaketanga ko te mōhiti tīwharawhara. Hei tauira, tukua Engineers nVidia he tau torutoru ki muri-marumaru mōhiti 3D ki arotahi karaihe wai. Hoki te faahuri kurupae marama whakarato arahina-backlight LCD mata mo te whakamahi o whiriwhiringa vahiraa. I roto i tenei take, kua kawea ngā i roto i kahore he anga motuhake, i roto i te puka o te rīpene. Kei arotahi Tāmau o te whānui o translucent ngohi huānga arahina, e kite i te kōrero ki te pūrere mana.

painga o te backlight

Whakaritea ki ētahi atu kōwhiringa rama, LED tino whakapai ake i te kounga o ngā mata kiritaki pouaka whakaata. Matua ake āhuatanga image tika - hua tenei i roto i te whakanui ake i te rerekē, me te tae uri. whakarato te tukatuka tūāwhiorangi tae kounga teitei RGB-kopu. I tua atu, arahina-backlight rerekē kohi mana iti. A tutuki whakaiti kohi hiko o runga ki te 40% i roto i ētahi wā. Hoki utu te tuhituhi ko te taea o te whakaputa mata ultrathin, e i te wa ano i te taimaha iti.

hapehape

Te mau melo pouaka whakaata hakari ki backlight arahina whakahē hoki ratou pānga kino o puru-puru radiation i runga i te kanohi. Hoki kitea kikorangi i roto i te "image" te nuinga e faahuru te reproduction tae tūturu. Heoi, i roto i nga putanga hou o te TV ki te nui -resolution mata arahina-backlight kua tata kahore taua mea kohakore. Ko reira he raruraru ki te whakahaere o te wherikotanga, i nei te pini wāhi whanui puoro. I roto i taua tautuhinga, kia kite koe i te kōpura mata.

mutunga

Ki te rā, te tauira wāhanga TV ki arahina-hangarau kei roto i tona tamarikitanga. Ahakoa aro mātai ana kiritaki nga whai wāhitanga me te rangatiratanga, e taea ki te whakarato i tētahi otinga auaha ko. Me kï reira e nohoia nga āhuatanga whakahaere arahina LED-rama, e kore e whakapoauau kaiwhakamahi utu rite tiketike. He maha ngā tohunga, whakaaro tenei take ko te ārai nui ki te popularization o te hangarau. Heoi, i te opuaraa no te LED tonu noho fafau, rite ratou utu ka iti haere rite piki tono. Whakarara ki tenei, me ētahi atu kounga rama ake, e atu faarahi te painga o te tuku.
