Njira Yoyang'anira Tile ya Pansi ya LED

Mawonekedwe a matailosi a LED ndi zida zoyambira masiku ano, zowonetsera zamalonda, ndi malo ochezera a zosangalatsa. Kuchita kwawo ndi kukhazikika kwawo kumakhudza mwachindunji zomwe wogwiritsa ntchito akukumana nazo. Kuti muwonetsetse kuti malonda ali abwino, njira yoyendera yokhazikika ndiyofunikira.

Maonekedwe ndi kuyang'anitsitsa kamangidwe ndizo njira zoyambirira. Akatswiri akuyenera kuona ngati malo owonetserako ndi athyathyathya komanso osakanda-opanda ma LED, ma LED amasanjidwa mofanana, komanso ngati furemu ndi bulaketi ndi zopunduka kapena zotayirira. Ayeneranso kutsimikizira kulimba kwa zigawo monga mawaya ma terminals ndi cholumikizira magetsi kuti apewe kulephera kobwera chifukwa cha zolakwika zamapangidwe.

Kuyesa kwamagetsi kumayang'ana pakuwunika kukhazikika kwamagetsi ndi kudalirika kwa ma siginecha. Zida zamaluso zimagwiritsidwa ntchito kuyeza ma voliyumu olowera ndi apano kuti zitsimikizire kuti zimakwaniritsa magawo ovotera ndikuteteza gawo lamagetsi kuti lisachuluke kapena ziwopsezo zazifupi. Oscilloscope imagwiritsidwanso ntchito kutsimikizira kukhulupirika kwa ma siginecha owongolera ndikuthetsa kuchedwa kufalitsa deta kapena kutayika kwa paketi.

Kuyesa kwa ntchito yowonetsera kumakhudza ma metrics atatu ofunika: kuwala, chromaticity, ndi liwiro la kuyankha. Photometer imagwiritsidwa ntchito kuyeza{{1}kufanana kwa kuwala kwa sikirini, zomwe zimafuna kuti zisinthidwe ndi zomwe zili mumakampani. Chowunikira chamitundu chimagwiritsidwa ntchito poyesa kulondola kwamitundu yofiira, yobiriwira, ndi yabuluu kuti zitsimikizire kusintha kwamitundu. Kuphatikiza apo, kusewerera kwapamwamba-kwanthawi zonse kumayerekezeredwa kuti muwone ngati ghosting kapena kulephera kwa pixel.

Kuyesa kusinthasintha kwa chilengedwe kumatengera momwe zinthu zimagwirira ntchito, kuphatikizapo kugwira ntchito mosalekeza m'malo otentha kwambiri-(60 digiri) ndi otsika-kutentha (-20 digiri) komanso kuyesa kukana chinyezi pa 95% chinyezi. Kuyesa kwamakina kugwedezeka kumatengera kukhudzidwa panthawi yamayendedwe kapena kukhazikitsa kuti zitsimikizire kuti palibe chiwopsezo cha ma solder ndi zolumikizira kukhala zomasuka.

Pomaliza, kuyezetsa kokwanira kophatikizana kumalumikiza zowonetsera ku makina owongolera kuti atsimikizire kulondola kwa magwiridwe antchito (monga kuzindikira ngati pali kuthamanga ndi capacitive touch), ndikuyesa-kuyesa kwanthawi yayitali (kupitilira maola 72) kuti awone ngati zalephera msanga.

Kupyolera mu njira zovomerezekazi, chitetezo, kudalirika, ndi zochitika za ogwiritsa ntchito zowonetsera matayala a LED zimatsimikiziridwa mokwanira, kuyala maziko olimba a kukhazikitsa ndi kugwiritsa ntchito motsatira.
