Zowonetsera za LED zikuphatikizana m'miyoyo yathu yatsiku ndi tsiku pa liwiro lomwe silinachitikepo, ndiSMD (Surface Mounted Chipangizo)teknoloji ikuwoneka ngati imodzi mwa zigawo zake zazikulu. Wodziwika chifukwa cha zabwino zake zapadera,Chiwonetsero cha SMD LEDalandira chidwi chofala. M'nkhaniyi,RTLEDadzateroonani mitundu, ntchito, zopindulitsa, ndi tsogolo la chiwonetsero cha SMD LED.
1. Kodi SMD LED Display ndi chiyani?
SMD, yachidule cha Surface Mounted Device, imatanthawuza chipangizo chokwera pamwamba. M'makampani owonetsera ma LED a SMD, ukadaulo wa SMD encapsulation umaphatikizapo kuyika tchipisi ta LED, mabatani, ma lead, ndi zinthu zina kukhala mikanda yaying'ono, yopanda lead ya LED, yomwe imayikidwa mwachindunji pama board osindikizira (PCBs) pogwiritsa ntchito makina oyika okha. Poyerekeza ndi ukadaulo wachikhalidwe wa DIP (Dual In-line Package), SMD encapsulation imakhala ndi kuphatikiza kwakukulu, kukula kochepa, komanso kulemera kopepuka.
2. Mfundo Zogwirira Ntchito za SMD LED
2.1 Mfundo ya Luminescence
Mfundo ya luminescence ya ma SMD LEDs imatengera mphamvu ya electroluminescence ya zida za semiconductor. Pamene panopa akudutsa pawiri semiconductor, ma elekitironi ndi mabowo kuphatikiza, kutulutsa mphamvu owonjezera mu mawonekedwe a kuwala, motero kukwaniritsa kuunikira. Ma LED a SMD amagwiritsa ntchito mpweya wozizira, m'malo motentha kapena kutuluka, zomwe zimapangitsa kuti azikhala ndi moyo wautali, nthawi zambiri kuposa maola 100,000.
2.2 Tekinoloje ya Encapsulation
Pakatikati pa SMD encapsulation yagona pa "kukwera" ndi "kugulitsa." Tchipisi za LED ndi zigawo zina zimayikidwa mu mikanda ya SMD LED kudzera munjira zolondola. Mikandayi imayikidwa ndi kugulitsidwa pa PCBs pogwiritsa ntchito makina oyika makina komanso ukadaulo wotenthetsera kwambiri.
2.3 Pixel Modules ndi Driving Mechanism
Mu chiwonetsero cha SMD LED, pixel iliyonse imakhala ndi mikanda imodzi kapena zingapo za SMD LED. Mikanda imeneyi ikhoza kukhala monochrome (monga yofiira, yobiriwira, kapena yabuluu) kapena yamitundu iwiri, kapena yodzaza. Pazowonetsera zamitundu yonse, mikanda yofiira, yobiriwira, ndi yabuluu ya LED imagwiritsidwa ntchito ngati gawo loyambira. Mwa kusintha kuwala kwa mtundu uliwonse kudzera mu dongosolo lolamulira, zowonetsera zamitundu yonse zimatheka. Gawo lililonse la pixel lili ndi mikanda yambiri ya LED, yomwe imagulitsidwa pa PCBs, ndikupanga gawo loyambira pazenera.
2.4 Control System
Makina owongolera a chiwonetsero cha SMD LED ali ndi udindo wolandila ndikusintha ma siginecha olowera, kenako kutumiza ma siginecha okonzedwa ku pixel iliyonse kuti awonere kuwala ndi mtundu wake. Dongosolo lowongolera nthawi zambiri limaphatikizapo kulandira ma siginecha, kukonza ma data, kutumiza ma siginecha, ndi kasamalidwe ka mphamvu. Kudzera m'mabwalo owongolera ovuta komanso ma aligorivimu, makina amatha kuwongolera pixel iliyonse, kuwonetsa zithunzi zowoneka bwino ndi makanema.
3. Ubwino wa SMD LED Display Screen
Tanthauzo Lapamwamba: Chifukwa chakuchepa kwa magawowo, ma pixel ang'onoang'ono amatha kutheka, ndikuwongolera kukoma kwazithunzi.
Kuphatikiza Kwapamwamba ndi Miniaturization: SMD encapsulation imapangitsa kuti pakhale zida zowoneka bwino, zopepuka za LED, zabwino kuphatikiza kachulukidwe kake. Izi zimathandizira ma pixel ang'onoang'ono komanso kukwezedwa kwapamwamba, kumathandizira kumveketsa bwino komanso kuthwa kwazithunzi.
Mtengo wotsika: Zopangira zokha pakupanga zimachepetsa ndalama zopangira, zomwe zimapangitsa kuti zinthuzo zikhale zotsika mtengo.
Kupanga Mwachangu: Kugwiritsa ntchito makina oyika okha kumathandizira kwambiri kupanga bwino. Poyerekeza ndi njira zachikhalidwe zogulitsira zamabuku, kuyika kwa SMD kumalola kukwera mwachangu kwa zigawo zazikulu za LED, kuchepetsa ndalama zogwirira ntchito komanso kuzungulira kwa kupanga.
Kutentha Kwabwino Kwambiri: SMD encapsulated LED zigawo zikuluzikulu ndi mwachindunji kukhudzana ndi bolodi PCB, amene facilitates kutentha kutha. Kuwongolera bwino kutentha kumatalikitsa moyo wa zida za LED ndikuwongolera kukhazikika ndi kudalirika kwa chiwonetsero.
Moyo Wautali: Kutentha kwabwino komanso kulumikizidwa kwamagetsi kokhazikika kumakulitsa nthawi yachiwonetsero.
Kukonza Kosavuta ndi Kusintha: Monga zigawo za SMD zimayikidwa pa PCBs, kukonza ndi kusintha ndizosavuta. Izi zimachepetsa mtengo ndi nthawi yokonza zowonetsera.
4. Mapulogalamu a SMD LED Ziwonetsero
Kutsatsa: Zowonetsera za SMD LED zimagwiritsidwa ntchito pafupipafupi pazotsatsa zakunja, zikwangwani, ndi zotsatsa, zotsatsa, nkhani, zolosera zanyengo, ndi zina zambiri.
Malo a Masewera ndi Zochitika: Zowonetsera za SMD LED zimagwiritsidwa ntchito m'mabwalo amasewera, makonsati, zisudzo, ndi zochitika zina zazikulu zowulutsa pompopompo, zosintha zamagulu, komanso kusewerera makanema.
Navigation and Traffic Information: Makoma a skrini a LED amapereka kuyenda ndi chidziwitso pamayendedwe apagulu, ma siginecha amsewu, ndi malo oimikapo magalimoto.
Banking ndi Finance: Makanema a LED amagwiritsidwa ntchito m'mabanki, kusinthanitsa masheya, ndi mabungwe azachuma kuwonetsa zidziwitso zamsika, mitengo yosinthira, ndi zidziwitso zina zachuma.
Utumiki wa Boma ndi Boma: Zowonetsera za SMD za LED zimapereka chidziwitso cha nthawi yeniyeni, zidziwitso, ndi zolengeza m'mabungwe a boma, malo apolisi, ndi malo ena ogwira ntchito zaboma.
Entertainment Media: Zowonetsera za SMD za LED m'makanema, zisudzo, ndi makonsati zimagwiritsidwa ntchito posewera ma trailer amakanema, zotsatsa, ndi zina zambiri.
Ma eyapoti ndi Masitima apamtunda: Zowonetsera za LED m'malo ochitirako mayendedwe monga ma eyapoti ndi masiteshoni a masitima apamtunda amawonetsa zambiri zapaulendo wanthawi yeniyeni, ndandanda ya masitima apamtunda, ndi zosintha zina.
Zowonetsa Zamalonda: Zowonetsera za SMD za LED m'masitolo ndi m'malo akuluakulu zimawulutsa zotsatsa, zotsatsa, ndi zina zambiri.
Maphunziro ndi Maphunziro: Zowonetsera za SMD LED zimagwiritsidwa ntchito m'masukulu ndi malo ophunzitsira pophunzitsa, kuwonetsa zambiri zamaphunziro, ndi zina.
Chisamaliro chamoyo: Makoma a kanema a SMD LED muzipatala ndi zipatala amapereka chidziwitso chachipatala ndi malangizo a zaumoyo.
5. Kusiyana pakati pa SMD LED Display ndi COB LED Display
5.1 Kukula kwa Encapsulation ndi Density
SMD encapsulation ili ndi miyeso yokulirapo yakuthupi ndi kukwera kwa ma pixel, oyenera mitundu yamkati yokhala ndi ma pixel okwera pamwamba pa 1mm ndi mitundu yakunja pamwamba pa 2mm. Kuphatikizika kwa COB kumachotsa choyikapo cha mikanda ya LED, kulola kukula kwakung'ono kwa encapsulation ndi kachulukidwe kakang'ono ka pixel, koyenera pamapulogalamu ang'onoang'ono a pixel, monga mitundu ya P0.625 ndi P0.78.
5.2 Mawonekedwe Owonetsera
SMD encapsulation imagwiritsa ntchito magwero owunikira, pomwe mawonekedwe a pixel amatha kuwoneka pafupi, koma kufanana kwamitundu ndikwabwino. COB encapsulation imagwiritsa ntchito magwero owunikira, omwe amapereka kuwala kofananira, mawonekedwe owoneka bwino, komanso kuchepetsedwa kwa granularity, kupangitsa kuti ikhale yoyenera kuwonera motalikirana m'makonzedwe monga malo olamulira ndi ma studio.
5.3 Chitetezo ndi Kukhalitsa
SMD encapsulation ili ndi chitetezo chochepa pang'ono poyerekeza ndi COB koma ndichosavuta kuchisunga, popeza mikanda ya LED imatha kusinthidwa mosavuta. COB encapsulation imapereka fumbi labwinoko, chinyezi, komanso kukana kugwedezeka, ndipo zowonera za COB zokwezeka zimatha kukwaniritsa kuuma kwa 4H, kuteteza ku kuwonongeka kwamphamvu.
5.4 Kuvuta kwa Mtengo ndi Kupanga
Ukadaulo wa SMD ndi wokhwima koma umaphatikizapo njira zovuta kupanga komanso zokwera mtengo. COB imathandizira kupanga mosavuta ndikuchepetsa mtengo, koma imafunikira ndalama zoyambira zida.
6. Tsogolo la SMD LED Display Screens
Tsogolo la zowonetsera za SMD LED lidzayang'ana pa luso laukadaulo lopitilizabe kupititsa patsogolo magwiridwe antchito, kuphatikiza makulidwe ang'onoang'ono a encapsulation, kuwala kwapamwamba, kutulutsa kwamitundu yochulukirapo, ndi ma angles owonera ambiri. Pamene kufunikira kwa msika kukukulirakulira, zowonetsera za SMD LED sizimangokhalira kukhalapo kolimba m'magulu azikhalidwe monga kutsatsa malonda ndi mabwalo amasewera komanso aziwunikanso mapulogalamu omwe akubwera monga kujambula kujambula komanso kupanga xR. Kugwirizana pakati pamakampani onse kudzapititsa patsogolo chitukuko chonse, kupindulitsa mabizinesi akumtunda ndi kumunsi. Kuphatikiza apo, chitetezo cha chilengedwe ndi machitidwe anzeru zidzasintha chitukuko chamtsogolo, kukankhira zowonetsera za SMD LED kunjira zobiriwira, zopatsa mphamvu zambiri, komanso zanzeru.
7. Mapeto
Mwachidule, zowonetsera za SMD LED ndizosankha zomwe mumakonda pamtundu uliwonse wazinthu kapena ntchito. Ndiosavuta kukhazikitsa, kusamalira, ndikugwiritsa ntchito, ndipo amaonedwa kuti ndi yabwino kuposa zosankha zachikhalidwe. Ngati muli ndi mafunso ena, omasuka kufunsatiuzeni tsopanokwa thandizo.
