1. Kuona kona
Iyo yekuona kona yechiratidzo che LED inoenderana nekona yekuona yemarambi e LED. Parizvino, vakawandakunze kwe LED kuratidzauyeindoor LED kuratidza skrini shandisa maSMD maLED ane horizontal uye vertical viewing angle ye140°. Kureba kwekuvaka kwe LED kuratidza kunoda akakwira vertical yekutarisa angles. Kutarisa kona uye kupenya kunopesana, uye kona yakakura yekuona inozoderedza kupenya. Sarudzo yekuona angle inoda kutariswa zvinoenderana nekushandiswa chaiko.
2. Kupenya
Kupenya kwebhedhi remwenje we LED chinhu chakakosha chinotaridza kupenya kwechiratidziro che LED. Iyo yakakwirira kupenya kwe LED, iyo yakakura muganho weiyo ikozvino inoshandiswa, iyo yakanaka kuchengetedza kushandiswa kwemagetsi uye kuchengetedza LED yakagadzikana. Ma LED ane maitiro akasiyana emakona. Kana kupenya kwechip kunogadziriswa, iyo idiki kona, iyo inopenya LED, asi iyo idiki yekuona kona yekuratidzira. Kazhinji, 120-degree LED inofanira kusarudzwa kuti ive nechokwadi chekutarisa kwakakwana kwekona yekuratidzira. Kune zviratidziro zvine madoti akasiyana uye madaro ekuona akasiyana, nzvimbo yekuenzanisa inofanira kuwanikwa mukupenya, kona uye mutengo.
3. Kukundikana kwehuwandu
Kubvayakazara ruvara rwe LED kuratidza inoumbwa nemakumi ezviuru kana kunyange mazana ezviuru zvemapixels anoumbwa neakatsvuka, girini uye bhuruu maLED, kutadza kwechero ruvara rwe LED kuchakanganisa kutaridzika kwese kwese kwe LED kuratidza. Kazhinji kutaura, mwero wekutadza kwekuratidzira kwe LED haufanire kunge wakakwira kupfuura 3/10,000 chiratidziro che LED chisati chatanga kuunganidzwa uye kuchembera kwemaawa makumi manomwe nemaviri isati yatumirwa.
4. Antistatic kugona
LED is a semiconductor device, iyo inonzwa kune static magetsi uye inogona kutungamirira nyore nyore kukundikana kwemagetsi. Naizvozvo, iyo anti-static kugona yakakosha kuhupenyu hweiyo skrini yekuratidzira. Kazhinji kutaura, kutadza kwemagetsi eLED yemuviri wemunhu electrostatic mode bvunzo haifanire kunge yakaderera pane 2000V.
5. Kuwirirana
Yakazara ruvara rwe LED kuratidza skrini inoumbwa nemapixels anoumbwa akawanda matsvuku, girini, uye bhuruu LEDs. Kuenderana kwekupenya uye kureba kwemavara ega ega LED kunotarisisa kujeka kunoenderana, chena chiyero kuenderana, uye chromaticity kuenderana kwese skrini yekuratidzira.
Rudzi rwakakwana rwe LED kuratidza ine angular directionality, kureva, kupenya kwayo kuchawedzera kana kuderera kana ichionekwa kubva kumakona akasiyana. Nenzira iyi, kuwirirana kweangular kwemavara matsvuku, egirinhi, uye bhuruu ma LED anozokanganisa zvakanyanya kuenderana kweyero chena pamakona akasiyana, uye zvakananga kukanganisa kutendeka kweruvara rwevhidhiyo pachiratidziro. Kuti uwane kuenderana kunoenderana kwekupenya kwekuchinja kwemavara matsvuku, egirinhi uye ebhuruu ma LEDs pamakona akasiyana, zvinodikanwa kunyatsoita dhizaini yesainzi mukugadzira lens yekurongedza uye kusarudzwa kwezvinhu zvakasvibirira, zvinoenderana nehunyanzvi hwekuita. mutengesi wekurongedza. Hazvina mhosva kuti yakanaka sei iyo yakajairika nzira chena chiyero, kana iyo LED angle kuenderana isina kunaka, iyo chena chiyero mhedzisiro yemakona akasiyana eiyo skrini yese ichave yakaipa.
6. Attenuation maitiro
Mushure mekunge kuratidzwa kwe LED kunoshanda kwenguva yakareba, kupenya kuchadonha uye ruvara rwechiratidziro ruchave rusingawirirani, izvo zvinonyanya kukonzerwa nekupenya kwekupenya kweiyo LED mudziyo. Iko kudzikisira kupenya kwe LED kunoderedza kupenya kweiyo yese LED kuratidza skrini. Kusaenderana kwekupenya kwekupenya kweiyo dzvuku, girini uye bhuruu LEDs kuchaita kuti kusawirirana kwemuvara we LED kuratidza. High mhando mwenje LED anogona kunyatso kudzora ukuru kupenya attenuation. Zvinoenderana neyakajairwa 20mA yekuvhenekesa pakamuri tembiricha kwemaawa 1000, iyo dzvuku attenuation inofanira kunge iri pasi pe2%, uye iyo yebhuruu uye yegirinhi attenuation inofanira kunge isingasviki gumi%. Naizvozvo, edza kusashandisa 20mA ikozvino yebhuruu uye girini maLED mudhizaini yekuratidzira, uye zvakanakisa kushandisa chete 70% kusvika 80% yeyakayerwa ikozvino.
Pamusoro peiyo attenuation maitiro ane hukama nehunhu hweiyo tsvuku, girinhi uye yebhuruu maLED pachawo, azvino anoshandiswa, kupisa kwekupisa dhizaini yePCB board, uye ambient tembiricha yechiratidziro zvese zvinokanganisa kudzikisira.
7. Saizi
Saizi yechigadzirwa che LED inokanganisa kureba kwepixel yeratidziro ye LED, ndiko kuti, kugadzirisa. Type SMD3535 LEDs anonyanya kushandiswaP6, P8, P10 kunze kwe LED kuratidza, SMD2121 LED inonyanya kushandiswaP2.5,P2.6,P2.97,P3.91 indoor screen . Pane fungidziro yekuti pixel pitch inoramba isina kuchinjika, saizi yemwenje ye LED inowedzera, iyo inogona kuwedzera nzvimbo yekuratidzira uye kuderedza huyo. Zvisinei, nekuda kwekuderedzwa kwenzvimbo yakasviba, kusiyana kuchaderedzwa. Pane zvinopesana, saizi ye LED inoderera,iyo inoderedza nzvimbo yekuratidzira uye inowedzera huyo, nzvimbo yakasviba inowedzera, ichiwedzera chiyero chekusiyanisa.
8. Hupenyu
Theoretical lifespan yemwenje we LED i100,000 maawa, ayo akareba kupfuura zvimwe zvikamu zve LED kuratidza hupenyu. Naizvozvo, chero bedzi mhando yemarambi e LED ichivimbiswa, kushanda ikozvino kwakakodzera, PCB yekupisa kupisa dhizaini inonzwisisika, uye nzira yekugadzira yekuratidzira yakasimba, mwenje we LED uchave wakanyanya kusimba zvikamu zve LED vhidhiyo madziro.
LED modules inotora 70% yemutengo wekuratidzwa kwe LED, saka ma LED modules anogona kuona kunaka kwe LED kuratidzwa. Iyo yepamusoro tekinoroji inodiwa ye LED kuratidza skrini ndiyo yeramangwana budiriro maitiro. Kubva pakutonga kwema LED modules, kusimudzira shanduko yeChina kubva kune yakakura LED kuratidza nyika yekugadzira kuenda kune ine simba LED kuratidza nyika kugadzira.
