M'dziko lamphamvu la ukadaulo wowoneka bwino, ziwanda za LED tsopano zakhala zosasangalatsa, zomwe zikuthandizira momwe chidziwitsocho zimaperekedwera ndikupanga zokumana nazo zozizwitsa. Kuganizira kofunikira pakuwonetsa mawonekedwe a LED ndikudziwitsa kukula koyenera kwa mapulogalamu osiyanasiyana. Kukula kwa chiwonetsero cha LED chimakhala ndi gawo lofunika kwambiri pakuwonetsetsa kuti kulumikizana bwino, kuwoneka, komanso kukhudzidwa. Munkhaniyi, tikusamala za zinthu zomwe zimayambitsaChiwonetsero cha LEDkukula ndikupereka chidziwitso pakupanga zisankho zodziwitsa.
Kuganizira koyambirira komanso kolojekiti posankha kukula kwaChithunzi cha LEDndiye mtunda wowonera. Ubwenzi wapakati pa kukula kwa zenera ndi kuwonera ndikofunikira kuti mukwaniritse mawonekedwe owoneka bwino. Mwachitsanzo. Komanso, m'malo ang'onoang'ono ngati malo ogulitsa kapena zipinda zowongolera, kukula kocheperako kumakwanira.
Chofunikira china ndichogwiritsa ntchito kugwiritsidwa ntchito kwa LED. Zotsatsa ndi zotsatsira, zojambula zambiri nthawi zambiri zimakonda kukopa chidwi cha omwe akudutsa ndi kupereka mauthenga moyenera. Mosiyana ndi izi, posonyeza chidziwitso cha ma eyapoti, malo amaphunzitsira, kapena makonda, mogwirizana pakati pa kukula komanso kuyanjana ndikofunikira kuwerengera wowonera.
Kusintha kwa chiwonetsero cha LED ndi gawo lotsutsa kwambiri. Chiwonetsero chachikulu chokhala ndi lingaliro lalitali kumatsimikizira kuti zomwe zili zimawoneka zakuthwa komanso zowoneka bwino, ngakhale atangoonera pafupi. Izi ndizofunikira kwambiri pazomwe zimagwiritsidwa ntchito pomwe zithunzi zatsatanetsatane kapena zolemba zimawonetsedwa, monga m'malo olamulira kapena zipinda zamisonkhano. Kugwedeza malire a kukula pakati pa kukula ndi kuthetsa ndikofunikira kuti muwone zomveka bwino.
Kodi ndi chiyani chomwe chikuyenera kukhala chophimba cha LED?
Ndikofunikira kwambiri kudziwa kuti sizachikulu posankha chophimba.
Cholinga apa ndikupewa mwatsatanetsatane zithunzi kapena malingaliro osafunikira (nthawi zina zimasiyana kutengera polojekiti). Ndi pixel phula lomwe limatsimikiza kuti pazenera komanso imapereka mtunda pakati pa matikiti mu mamilimita. Ngati mtunda pakati pa ma LED umatsika, kusintha kumawonjezeka, pomwe mtunda ukuwonjezeka, kusinthaku kumachepa. Mwanjira ina, kuti mupeze chithunzi chosalala, chophimba chaching'ono chikuyenera kukhala chovuta kwambiri (osachepera 43,000 pixels ocheperako kuti asataye zambiri), kapena mosemphanitsa, pazenera lalikulu, chizolowezi chiyenera kuchepetsedwa ma pixel 43,000. Siyenera kuiwala kuti zowonera zomwe zikuwonetsa kanema pazinthu zabwinobwino ziyenera kukhala ndi pixel yocheperako iyenera kukhala ndi pixel yolimbitsa thupi (yeniyeni), komanso kukula kwakukulu kwa chikhodzodzo kuyenera kukhala ndi pixel yolimbitsa thupi (kwenikweni).
Chophimba chachikulu cha LED
Ngati mukufuna kuyika chinsalu chachikulu mu chisoti chachidule (mwachitsanzo, mita 8), tikukulimbikitsani kuti mugwiritse ntchito chithunzi cha LED ndi pixel yokha. Nambala yowerengera pixel imawerengeredwa pochulukitsa pixel ya pixel pofika 4. Izi zikutanthauza kuti ngati chophimba cha LED 50,000 chimakhala ndi ma pixel (enieni), pali ma pixol 200,000 omwe alipo. Mwanjira imeneyi, pazenera ndi pixel yocheperako, mtunda wocheperako umachepetsedwa kukhala theka poyerekeza ndi chophimba ndi pixel yeniyeni.
Kodi mumawona bwanji Faible yapafupi kwambiri yomwe ili mtunda wa wowonera wapafupi ndi zenera limawerengedwa ndi hypotenuse.
Kodi Ndingawerenge Bwanji Hypotenuse? Hypotenise imawerengeredwa ndi a Pythagorean theorem motere:
H²½² + ndiku
H: Kuwonera mtunda
L: Kutali kuchokera pansi
H: kutalika kwa chinsalu kuchokera pansi
Mwachitsanzo, mtunda wowonera wa munthu 12m pamwamba pa nthaka ndi 5m kutali ndi nsalu yowerengedwa ngati:
HOR = " HRE = 25 + 144? HR = 169? H =? 169? 13mo
Zinthu zachilengedwe siziyenera kusokonezedwa posankha kukula kwa chiwonetsero cha LED. M'makina osinthira kunja, monga mafinya a digito kapena zojambula za stadital, kukula kwambiri nthawi zambiri ndizofunikira kudziwitsa omvera ambiri. Kuphatikiza apo, kuwonetsa zakunja kuyenera kukhala ndi zida zolimbana ndi nyengo yosiyanasiyana, kumapangitsanso kusankha kwa kukula ndi zida.
Pomaliza, kukula koyenera kwa zojambula za LED ndi chisankho chomwe chimadalira zinthu monga kuwonera mtunda, zomwe cholinga, malingaliro ake, komanso malingaliro azachilengedwe. Kuganizira zinthu izi kumatsimikizira kuti kukula kosasankhidwa kumagwirizana ndi zofunikira za pulogalamuyi, ndikuwonetsa zowoneka bwino. Monga ukadaulo ukupitilirabe, kupeza njira yoyenera pakati pa kukula ndi magwiridwe antchito adzakhala kofunikira pakukakamizidwaZithunzi zowonetserakudutsa mafakitale osiyanasiyana.
