Khoma lakukhota la LED

Ma screen ghanandi gha LED ghakukhozga. Mukupokera panelo yakuphapha, ndipo ndivyo. Usange mukukhumba malo ghakukhota – mzati wakuvikilira, mafunde, silinda – mulije mwaŵi kwambura kuti mwapanga chinthu chakudura mwakuyana na umo mukukhumbira.

Khoma la Kuwoneska la LED lakukhota likumazga fundo iyi. Iwo wakuzengeka kuzingilizga PCB yakusinthasintha na chivundikiro cha silikoni chakufewa cha kumanyuma. Module yose yikukhota. Pachoko waka yayi – mpaka 135℃mu vigaŵa vyose viŵiri. Mungazingilizga pa mzati, kuyikhoma mu kawonekero ka S, panji kupanga mafunde agho palije chithuzithuzi chakuphapha icho chingakwaniska. Ndipo para mwamara, yikuperekaso 6000: 1 kupambana na 3840Hz kusinthiska.

Chinsinsi chili mu vinthu viŵiri. Chakwamba, bolodi la dera ni chinthu chakusinthasintha, ni fiberglass yakukhora yayi. Iwo wakukhoma kwambura kung'amba vimanyikwiro. Chachiŵiri, chibenekelero cha kumanyuma chikupangika na silikoni, pulasitiki wakukhora yayi. Silikoni iyo yikupangiska kuti yiŵe na nkhongono zakupotoloka na kukhotakhota kwambura kuphyoka panji kutaya kawonekero kake.

Ma modules nagho ghakuwonda chomene – pasi pa 7.8mm. Icho nchakuzirwa para mukukutira radius wakukhora. Para module njakuwonda, mzati uwo ungaphimba ukuŵa uchoko.

Kumbuyo kuli magneti ghakukhora ghakupangika. Kuŵika nkhwakukhozga: ŵikani chigaŵa ichi pa chigaŵa cha chisulo, ndipo maginito ghakuchikora. Palije vikuŵika pa kunthazi. Para mukukhumba kuwuskapo module kuti muyipwelelere, mukuyikoka kufuma ku kunthazi – palije chifukwa chakuti mufike kumanyuma. Icho nchinthu chikuru chomene para chithuzithuzi chikuzingilizgika na mzati kwambura nthowa yakunjilira kumanyuma.

Chigaŵa ichi chingakhota kufika pa msinkhu wa pafupifupi 110mm ku viyerezgero vichoko chomene vya mzere, ndipo msinkhu ukuru wa mzere unyake. Mu mazgu ghakuchitika, mungazingilizga pa mzati wakuwonda nga ni mtengo wa msewu. Mtundu wakukhota ukufika pa 135℃mu vigaŵa vyose viŵiri vyakukhozga na vyakukhozga - ivyo ni vyakukwana chomene ku mapangidwe ghanandi ghakupanga.

 

Tikawona ŵanthu ŵakupanga vithuzithuzi vyakuwoneka nga ni silinda, makoma gha mabingu, ma S‐curve, nanga ni vinthu vyakuyana na vyakuzungulira. Chivundikiro cha silikoni cha kumanyuma chikuphyoka yayi panji kukhotakhota, ndipo PCB yakusinthasintha yayezgeka kuti yizizipizge kupindika mwakuwerezgawerezga kwambura kuswa magesi.

Para ŵanthu ŵakupulika "kusinthasintha", nyengo zinyake ŵakughanaghana kuti chithunzithunzi chiŵenge chakufewa panji chakupotoloka. Kuno yayi. Ma chips gha LED ni SMD 3‐in‐1, ghakuyana waka na chiwoneskero chilichose chiwemi cha mu nyumba. Kupambana kuli 6000:1. Kubwezereska ni 3840Hz – palije kuwala pa kamera. Grayscale yikufika pa 14‐bit, ntheura vigaŵa vyakukhozga vikuŵa vyakusalala.

Kuŵala kukuyamba pa 450 mpaka 700 nits kuyana na msinkhu wa pixel. Icho nchakukwana kugwiriskira ncito mu nyumba – maholo gha maungano, vipinda vyakulongolera, nyumba zakusungiramo vinthu vyakale, masitudiyo gha TV.

Nthowa zakusankhapo za pixel zikufuma pa 0.9mm mpaka pa 4mm, ndipo vigaŵa ivi ni 320 × 160mm, 200 × 150mm, 240 × 120mm, 250 × 125mm, na 320 × 180mm. Mungasakanizga masaizi ghakupambanapambana mu khoma limoza usange mukukhumbikwira.

Kukwera kwa maginito kukuponoska nyengo.Munthu yumoza wangaŵika mtenje wose. Kankhirani chigaŵa ichi pa chigaŵa cha chisulo, ndipo maginito ghakuchiŵika pa malo ghake. Palije vikuŵikamo vyakuŵika pa malo ghakwenelera, palije vipangizo. Para mukukhumba kusintha module, muwuskemo kufuma ku kunthazi – ukukoleka na maginito ghakukhora mwakukwana kuti ghakhalepo kweni ghakukhora chomene yayi mwakuti mukukhumbikwira pry bar.

 

Kumbuyo kwa silikoni kukuuma yayi.Vinthu vyakutchipa vyakusinthasintha vingakhoma na kung’ambika para pajumpha vyaka vichoko waka. Silicone iyo yikugwiriskirika nchito pano yikupangika kuti yiŵe yakusinthasintha kwa nyengo yitali. Iwo ukukhala wakufewa na wakukhora nangauli wakhala wakukhota kwa vilimika vinandi.

Mungasakanizga vigaŵa vyakukhotakhota na vyakuphapha.Nyengo zinyake chigaŵa chimoza pera cha mtenje ndicho chikukhumbikwira kukhota. Vinyake vyose vingaŵa vigaŵa vyakuphapha vyakumanyikwa. Ŵakugaŵana pixel pitch yimoza na magesi, ntheura ŵakugwira ntchito pamoza kwambura kusuzga.

Kasi ni radius wuli yichoko chomene iyo ningakhoma ichi?
Icho chikuthemba pa pixel pitch. Pakuti chigaŵa cha 1.2mm cha msinkhu, msinkhu wa msinkhu uli pafupifupi 110mm. Kwa mapichi ghakuru nga ni 4mm, ghali pafupifupi 400mm. Wonani pepala la spec kuti mumanye mazgu ghinu ghakwenelera.

Kasi ningayikhoma para nayiŵika?
Ma module ghapangika kuti ghaŵikike kale ghakukhota. Mukuŵakhoma mwakuwerezgawerezga nga ni hinge yayi. Para mwaŵika curve na kuyikwezga, yikukhala mu kawonekero ako.

Kasi nkhukhumba furemu yapadera?
Enya – mukukhumbikwira chigaŵa cha chisulo chakukhota icho chikuyana na radius iyo mukukhumba. Magneti ghakugwira ntchito pa chinthu chilichose cha chisulo cha ferrous. Tingapereka ulongozgi wakupangira furemu.

Kasi ningasintha wuli chigaŵa icho chili pakati pa mtenje wakukhota?
Ivyo vikuyana waka na mpanda wakuphapha. Gwiliskirani nchito kapu yakuyamwa kuti mukoke chigaŵa kufuma ku kunthazi. Magneti ghakufumiskika na kukoka mwakukhora. Kufuma apo, fumyanipo khebo ya riboni na magesi, ŵikanimo chigaŵa chiphya, na kuchikanizgaso. Khoma lose ilo likukhalapo likulutilira kuchimbira.

Kasi likuŵikika kuwaro?
Yayi, ichi nchinthu cha mu nyumba. Kutentha kwakugwira ntchito -10 digiri mpaka 50 digiri , chinyezi 10‐90% chambura kuthukira. Pa vithuzithuzi vyakusinthasintha vya kuwaro, fumbani vya mtundu wa kuwaro.
