LED yerekanwa igizwe numurongo wumucyo usohora diode, kubwibyo ubwiza bwa LED bugira ingaruka kuburyo butaziguye ubwiza bwerekana
1. Umucyo nu mfuruka yo kureba
Umucyo wo kwerekana ecran ahanini biterwa nuburemere bwurumuri hamwe nubucucike bwa LED.Mu myaka yashize, tekinolojiya mishya ya LED muri substrate, epitaxy, chip na pack byagaragaye bidasubirwaho, cyane cyane ituze nubukure bwa tekinoroji yo kwaguka igezweho hamwe nuburyo bwa indium tin oxyde (ITO), yazamuye cyane ubukana bwa LED .Kugeza ubu, hashingiwe ko inguni itambitse yo kureba ari dogere 110 naho impagarike ihagaritse yo kureba ni dogere 50, ubukana bw'urumuri rw'icyatsi kibisi bwageze kuri mcd 4000, umuyoboro utukura wageze kuri mcd 1500, naho umuyoboro w'ubururu ufite yageze kuri mcd 1000.Iyo umwanya wa pigiseli ari 20mm, umucyo wa ecran yerekana urashobora kugera kuri 10,000nit.Iyerekana irashobora gukora amasaha yose mubidukikije
Iyo uvuze ibyerekeranye na ecran yerekana, hari ikintu gikwiye gutekereza: LED yerekana ibyerekanwe, cyane cyane ibyerekanwa hanze, bigaragara cyane uhereye hasi hejuru, mugihe muburyo bwa ecran ya LED ihari, kimwe cya kabiri cya luminous flux izimira mu kirere kinini.
2. Guhuriza hamwe no gusobanuka
Hamwe niterambere rya LED yerekana ikoranabuhanga, uburinganire bwabaye ikimenyetso cyingenzi cyo gupima ubuziranenge bwerekana.Bikunze kuvugwa ko LED yerekana "ari nziza muri buri kintu kandi ikaba nziza muri buri gice", ikaba ari ikigereranyo cyerekana ubusumbane bukabije hagati ya pigiseli na modul.Amagambo yumwuga ni "ingaruka zumukungugu" na "mosaic phenomenon".
Impamvu nyamukuru zitera ibintu bitaringaniye ni: ibipimo bya LED imikorere idahuye;Iteraniro ridahagije ryerekana ecran mugihe cyo gukora no kuyishyiraho;Ibipimo by'amashanyarazi mubindi bikoresho bya elegitoronike ntabwo bihuye bihagije;Igishushanyo cya module na PCBs ntabwo gisanzwe.
Impamvu nyamukuru ni "ukudahuza ibipimo bya LED".Ibidahuye nibi bipimo byimikorere harimo cyane cyane: ubukana bwurumuri rudahuye, umurongo wa optique udahuye, guhuza ibara rihuza, guhuza urumuri rutagabanije gukwirakwiza umurongo wa buri bara ryibanze, hamwe nibiranga guhuza.
Nigute wakemura ibibazo bidahuye nibikorwa bya LED, hariho inzira ebyiri zingenzi za tekiniki mu nganda muri iki gihe: icya mbere, kunoza imikorere ya LED ukomeza kugabanya ibipimo byerekana LED;Ibindi ni ukunoza uburinganire bwa ecran yerekana binyuze mugukosora gukurikira.Ubugororangingo bwakurikiyeho nabwo bwateje imbere kuva hakiri kare gukosora no gukosora module kugeza ku ngingo yuyu munsi ku gukosora ingingo.Ikoranabuhanga ryo gukosora ryateye imbere kuva urumuri rworoheje rukosora kugeza urumuri rwinshi rwamabara ihuza ikosora.
Ariko, twizera ko gukosorwa gukurikira bidashobora byose.Muri byo, ukudahuza umurongo wa optique, kudahuza umurongo wo gukwirakwiza urumuri rwinshi, kudahuza ibiranga attenuation, kutamenya neza inteko hamwe nigishushanyo mbonera ntigishobora gukurwaho hifashishijwe ubugororangingo bwakurikiyeho, ndetse no gukosorwa gukurikiraho bizarushaho guhuza umurongo wa optique. , kwitonda no guterana neza.
Kubwibyo, binyuze mumyitozo, umwanzuro twafashe nuko gukosorwa gukurikiraho ari umuti gusa, mugihe kugabana ibipimo bya LED aribyo ntandaro hamwe nigihe kizaza cya LED yerekana inganda.
Kubijyanye nubusabane hagati ya ecran nubusobanuro, akenshi habaho kutumvikana munganda, ni ukuvuga, imyanzuro isimbuza ibisobanuro.Mubyukuri, ubusobanuro bwa ecran yerekana ni ibyiyumvo bifatika byijisho ryumuntu kumyanzuro, uburinganire (igipimo cyerekana-urusaku), umucyo, itandukaniro nibindi bintu byerekana ecran.Kugabanya gusa umwanya wa pigiseli igaragara kugirango utezimbere imyanzuro, mugihe wirengagije uburinganire, ntagushidikanya kunoza neza.Tekereza ecran yerekana ifite "ingaruka zumukungugu" na "mosaic phenomenon".Nubwo imiterere ya pigiseli yumubiri ari nto kandi ikemurwa ni ndende, ntibishoboka kubona igishusho cyiza.
Kubwibyo, muburyo bumwe, "uburinganire" aho kuba "umwanya wa pigiseli igaragara" kuri ubu bigabanya iterambere rya LED yerekana ibisobanuro.
3. Erekana pigiseli ya ecran idateganijwe
Hariho impamvu nyinshi zerekana ecran ya ecran ya ecran kugirango igenzurwe, icyingenzi muri byo ni "gutsindwa kwa LED".
Impamvu nyamukuru zitera LED kunanirwa zishobora kugabanywamo ibice bibiri: imwe nubwiza buke bwa LED ubwayo;Icya kabiri, uburyo bwo gukoresha ntibukwiye.Binyuze mu gusesengura, dusoza isano ijyanye hagati yuburyo bwa LED bwo gutsindwa nimpamvu ebyiri nyamukuru.
Nkuko byavuzwe haruguru, kunanirwa kwinshi kwa LED ntibishobora kuboneka mugusuzuma bisanzwe no kugerageza LED.Usibye gukorerwa amashanyarazi ya electrostatike, umuyoboro munini (utera ubushyuhe bukabije bwo guhuza), imbaraga zo hanze nubundi buryo budakwiye, kunanirwa kwinshi kwa LED biterwa nihungabana ryimbere ryimbere riterwa na coefficient zitandukanye zo kwagura ubushyuhe bwa chipi ya LED, resin epoxy, inkunga, imbere kuyobora, ibyuma bikomeye bya kirisiti, ibikombe bya PPA nibindi bikoresho munsi yubushyuhe bwinshi, ubushyuhe buke, ubushyuhe bwihuse cyangwa ibindi bihe bibi.Kubwibyo, LED kugenzura neza ni umurimo utoroshye.
4. Ubuzima
Ibintu bigira ingaruka mubuzima bwa LED yerekana ecran harimo ibintu byimbere ninyuma, harimo imikorere yibice bya periferique, imikorere yibikoresho bitanga urumuri rwa LED, hamwe no kurwanya umunaniro wibicuruzwa;Ibintu byimbere harimo ibidukikije bikora bya LED yerekana ecran, nibindi.
1).Ingaruka yibigize
Usibye ibikoresho bitanga urumuri rwa LED, LED yerekana kandi ikoresha ibindi bice byinshi bya periferiya, harimo imbaho zumuzunguruko, ibishishwa bya pulasitike, guhinduranya amashanyarazi, umuhuza, chassis, nibindi. Ikibazo cyose nikintu kimwe gishobora kugabanya ubuzima bwerekanwa.Kubwibyo, ubuzima burebure bwa ecran yerekana bugenwa nubuzima bwibintu byingenzi hamwe nubuzima bugufi.Kurugero, LED, guhinduranya amashanyarazi hamwe namazu yicyuma byose byatoranijwe ukurikije imyaka 8, mugihe ibikorwa byo gukingira ikibaho cyumuzunguruko bishobora gushyigikira imirimo yacyo mumyaka 3 gusa.Nyuma yimyaka 3, izangirika kubera ruswa, bityo dushobora kubona gusa ecran yimyaka 3 yerekana.
2).Ingaruka yumucyo wohereza ibikoresho bya LED
LED itanga urumuri nibintu byingenzi kandi bifitanye isano nubuzima bwa ecran yerekana.Kuri LED, ikubiyemo cyane cyane ibipimo bikurikira: ibiranga attenuation, ibiranga imyuka y'amazi, hamwe no kurwanya ultraviolet.Niba uruganda rwerekana LED rwananiwe gutsinda isuzumabumenyi ku mikorere yerekana ibikoresho bya LED, bizashyirwa mu bikorwa, bizatera impanuka nyinshi z’ubuziranenge kandi bigira ingaruka zikomeye ku buzima bwa LED.
3).Ingaruka zo kurwanya umunaniro wibicuruzwa
Imikorere yo kurwanya umunaniro wibicuruzwa bya ecran ya LED biterwa nuburyo bwo gukora.Biragoye kwemeza imikorere irwanya umunaniro module yakozwe nuburyo butatu bwo kuvura.Iyo ubushyuhe nubushuhe bihindutse, ubuso burinda ikibaho cyumuzunguruko bizagaragara nkibice, biganisha kumikorere yibikorwa.
Kubwibyo, uburyo bwo gukora LED yerekana ecran nayo ni ikintu cyingenzi cyo kumenya ubuzima bwa ecran yerekana.Igikorwa cyo kubyaza umusaruro kigira uruhare mubikorwa byo kwerekana ecran ikubiyemo: uburyo bwo kubika no gutunganya ibintu, uburyo bwo gusudira itanura, uburyo butatu bwo kwerekana ibimenyetso, uburyo bwo gufunga amazi, n'ibindi. Ingaruka yimikorere ijyanye no guhitamo no kugereranya ibikoresho, kugenzura ibipimo na ubuziranenge bw'abakora.Kubantu benshi ba LED berekana, gukusanya uburambe nibyingenzi.Uruganda rufite uburambe bwimyaka myinshi ruzagenzura imikorere yumusaruro neza.
4).Ingaruka zakazi
Bitewe nintego zitandukanye, imikorere yimikorere ya ecran iratandukanye cyane.Ku bijyanye n'ibidukikije, itandukaniro ry'ubushyuhe bwo mu nzu ni rito, kandi nta ngaruka z'imvura, shelegi n'umucyo ultraviolet;Itandukaniro ntarengwa ry'ubushyuhe hanze rishobora kugera kuri dogere 70, wongeyeho umuyaga, izuba n'imvura.Ibidukikije bibi bizongera gusaza kwa ecran yerekana, kandi ibidukikije bikora ni ikintu cyingenzi kigira ingaruka mubuzima bwa ecran.
Ubuzima bwa LED yerekana ecran bugenwa nibintu byinshi, ariko iherezo ryubuzima ryatewe nibintu byinshi rirashobora kwagurwa muburyo bwo gusimbuza ibice (nko guhinduranya amashanyarazi).Ariko, LED ntishobora gusimburwa kubwinshi.Kubwibyo, iyo ubuzima bwa LED bumaze kurangira, bivuze ubuzima bwo kwerekana ecran irangiye.
Tuvuze ko ubuzima bwa LED bugena ubuzima bwa ecran yerekana, ariko ntabwo dushaka kuvuga ko ubuzima bwa LED bungana nubuzima bwa ecran yerekana.Kubera ko ecran yerekana idakora kumurimo wuzuye mugihe cyose ikora, igihe cyo kwerekana ecran igomba kuba inshuro 6-10 za LED mugihe ikina progaramu ya videwo bisanzwe, kandi ubuzima bwa LED burashobora kuba birebire iyo ikora kumurongo muto.Kubwibyo, ubuzima bwa LED bwerekana ecran hamwe niki kirango gishobora kugera kumasaha 50000.
