Ko munhu akasarudzika angasiyanisa sei kunaka kweiyo LED kuratidza? Kazhinji, zvakaoma kugonesa mushandisi zvichienderana nekuzviruramisa kwemutengesi. Pane akati wandei akapusa nzira dzekuona kunaka kweiyo yakazara ruvara LED kuratidza skrini.
1. Kufuratira
Iyo yekumusoro kupfava kweiyo LED skrini yekuratidzira inofanirwa kunge iri mukati me ± 0.1mm kuti ive nechokwadi chekuti mufananidzo wakaratidzwa hauna kukanganisa. Zvidimbu zvakasara kana zvimisikidzo zvinotungamira kune yakafa kona mukona yekutarisa ye LED kuratidza skrini. Pakati pekabati ye LED uye kabati ye LED, gaka riri pakati pemodule uye module rinofanira kunge riri mukati me 0.1mm. Kana gaka racho rakakura zvakanyanya, muganho we LED kuratidza skrini ichave pachena uye chiratidzo hachizorongerwe. Hunhu hwe flatness hunonyanya kutsanangurwa nekugadzira maitiro.
2. Kupenya
Kupenya kweindoor LED skriniinofanira kuva pamusoro pe800cd/m2, uye kupenya kwekunze kwe LED kuratidzainofanira kunge iri pamusoro pe5000cd/m2 kuti ive nechokwadi chekuona kwechiratidziro che LED, zvikasadaro mufananidzo unoratidzwa hauzonyatsojeka nekuti kupenya kwakadzikira. Kupenya kweiyo LED skrini skrini haina kupenya sezvinobvira, inofanirwa kuenderana nekupenya kweiyo LED package. Kuwedzera upofu ikozvino kuti uwedzere kupenya kuchaita kuti iyo LED ideredze nekukurumidza, uye hupenyu hwekuratidzwa kwe LED huchadzikira nekukurumidza. Kupenya kwe LED kuratidzwa kunonyanya kutsanangurwa nemhando yemwenje we LED.
3. Kuona kona
Iyo kona yekutarisa inoreva iyo yakanyanya kona iyo iwe yaunogona kuona iyo yakazara LED skrini yemukati kubva kune iyo LED vhidhiyo skrini. Saizi yekona yekutarisa inotarisisa vateereri veiyo LED skrini yekuratidzira, saka iyo yakakura zvirinani, kona yekutarisa inofanira kupfuura 150 madhigirii. Saizi yekona yekutarisa inonyanya kutsanangurwa nenzira yekurongedza yemarambi e LED.
4. White balance
White balance effect ndiyo inonyanya kukosha zviratidzo zve LED kuratidza. Panyaya yeruvara, chena chaiyo icharatidzwa kana reshiyo yemavara matatu ekutanga ered, girinhi nebhuruu ari 1:4.6:0.16. Kana pane kutsauka kuduku muchiyero chaicho, pachava nekutsauka muchiyero chechena. Kazhinji, zvinodikanwa kuti utarise kuti chena iri bluish kana yero. green phenomenon. Mune monochrome, iyo idiki mutsauko mukupenya uye wavelength pakati pe LEDs, zviri nani. Iko hakuna mutsauko wemavara kana ruvara rwakakandwa kana wakamira padivi pechidzitiro, uye kuwirirana kuri nani. Hunhu hweyerero chena hunonyanya kutsanangurwa nereshiyo yekupenya uye wavelength yemwenje we LED uye iyo yekudzora sisitimu ye LED kuratidza skrini.
5. Rudzi kuderedza
Rudzi rwekudzoreredza runoreva ruvara runoratidzwa pachiratidziro che LED chinofanira kuenderana zvakanyanya neruvara rwenzvimbo yekutamba, kuitira kuti uve nechokwadi chechokwadi chemufananidzo.
6. Kana paine mosaic uye dead spot phenomenon
Mosaic inoreva masikweya madiki anogara akajeka kana anogara ari matema pane yekuratidzira LED, inova chiitiko chemodule necrosis. Chikonzero chikuru ndechekuti mhando yeIC kana marambi emarambi anoshandiswa muratidziro ye LED haina kunaka. Dead point inoreva imwe poindi inogara yakapenya kana inogara yakasviba pachiratidziro che LED. Huwandu hwemapoinzi akafa anonyanya kutariswa nemhando yefa uye kana matanho emugadziri e-anti-static akakwana.
7. Iine kana isina mavara mabhuroki
Ruvara block inoreva mutsauko uri pachena wemuvara pakati peadhuze mamodule. Iko kushanduka kwemavara kunobva pane module. Iyo color block phenomenon inonyanya kukonzerwa neiyo yakaipa control system, yakaderera grey level uye yakaderera scanning frequency.
8. Ratidza kugadzikana
Kugadzikana kunoreva hunhu hwakavimbika hwekuratidzwa kwe LED mudanho rekuchembera mushure mekunge rapera.
9. Chengetedzo
Chiratidziro che LED chinoumbwa nemakabati akawanda e LED, imwe neimwe kabhineti ye LED inofanira kuiswa pasi, uye kuramba kwepasi kunofanira kunge kuri pasi pe0.1 ohms. Uye inogona kumira yakakwirira voltage, 1500V 1min pasina kuputsika. Yambiro zviratidzo uye masirogani anodiwa pane yakakwira-voltage yekuisa terminal uye yakakwirira-voltage wiring yemagetsi.
10. Kurongedza uye Kutumira
Chiratidziro che LED chinhu chakakosha chine uremu hukuru, uye nzira yekurongedza inoshandiswa nemugadziri yakakosha. Kazhinji, inoputirwa mune imwe kabati ye LED, uye imwe neimwe pamusoro peiyo LED kabati inofanirwa kunge iine zvinhu zvinodzivirira kuti zvibate, kuitira kuti iyo LED ive nenzvimbo shoma yezviitiko zvemukati panguva yekufambisa.
