1. Intshayelelo
Iphaneli yokubonisa i-LED esemgangathweni inokhuseleko olubuthathaka kumanzi, amanzi, kunye nothuli, ihlala idibana nale miba ilandelayo:
Ⅰ. Kwiindawo ezifumileyo, iibhetshi ezinkulu zeepikseli ezifileyo, izibane ezaphukileyo, kunye neziganeko “zobubungu” zihlala zisenzeka;
Ⅱ. Ngexesha lokusetyenziswa kwexesha elide, umphunga womoya womoya kunye nokutshiza kwamanzi kunokonakalisa ubuhlalu besibane se-LED;
Ⅲ. Ukuqokelelana kothuli ngaphakathi kwesikrini kukhokelela ekulahlekeni okungalunganga kobushushu kunye nokuguga okukhawulezileyo kwesikrini.
Ukubonisa ngokubanzi kwe-LED yangaphakathi, iipaneli ze-LED zihlala zihanjiswa kwimeko ye-zero-fault kumzi-mveliso. Nangona kunjalo, emva kwexesha lokusetyenziswa, imiba efana nezibane eziphukileyo kunye nokukhanya komgca kaninzi kwenzeka, kwaye ukungqubana okungeyonjongo kunokubangela ukuhla kwesibane. Kwiindawo zofakelo, iimeko ezingalindelekanga okanye ezingafanelekanga ngamanye amaxesha zinokuqubisana nazo, ezifana neziphene ezinkulu ezibangelwa kukwahluka kwamaqondo obushushu asuka kwiindawo zokupholisa umoya ezivuthela ngokuthe ngqo kuluhlu olusondeleyo, okanye ukufuma okuphezulu okubangela ukonyuka kwamazinga empazamo yesikrini.
Yeyangaphakathiumboniso oqaqambileyo we-LEDumthengisi onokuhlolwa kwesiqingatha sonyaka, ukujongana nemiba efana nokufuma, uthuli, ukungqubana, kunye namazinga eempazamo, kunye nokuphucula umgangatho wemveliso ngelixa unciphisa umthwalo wenkonzo emva kokuthengisa kunye neendleko ziyinkxalabo ebalulekileyo kubaboneleli be-LED.
Umzobo 1. I-short-short-circuit embi kunye nekholamu yokukhanyisa isiganeko somboniso we-LED
2. RTLED kaThixo AOB Coating Solution
Ukujongana ngempumelelo nale miba,I-RTLEDyazisa i-AOB (Advanced Optical Bonding) isisombululo sokugquma. Izikrini zetekhnoloji yokugquma i-AOB zahlulahlula iityhubhu ze-LED kunxibelelwano lwangaphandle lweekhemikhali, zithintela ukufuma kunye nokungena kothuli, ziphucula kakhulu ukusebenza kokhuseleko lwethu.Izikrini ze-LED.
Esi sisombululo sisekelwe kwinkqubo yokuvelisa i-LED ekhoyo yangaphakathi, edibanisa ngokufanelekileyo kunye nemigca yokuvelisa i-SMT (i-Surface Mount Technology) ekhoyo.
Umzobo 2. Umzobo ocwangcisiweyo wezixhobo zokugquma umphezulu (umphezulu okhanyayo)
Inkqubo ethile yile ilandelayo: emva kokuba iibhodi ze-LED zenziwe kusetyenziswa iteknoloji ye-SMT kwaye ineminyaka engama-72 iiyure, i-coating ifakwe kwibhodi yebhodi, yenza uluhlu olukhuselayo olufaka izikhonkwane ze-conductive, ezikhuselayo kwimiphumo yomswakama kunye nomphunga, njengoko kubonisiwe. kuMfanekiso 3.
Kwimveliso ye-LED jikelele yokubonisa kunye nenqanaba lokukhusela le-IP40 (IPXX, i-X yokuqala ibonisa ukukhuselwa kothuli, kwaye i-X yesibini ibonisa ukukhuselwa kwamanzi), iteknoloji yokugqoka i-AOB iphucula ngokufanelekileyo umgangatho wokukhusela we-LED, inika ukhuseleko lokungqubana, ikhusela ukuhla kwesibane. , kwaye inciphisa ireyithi yempazamo yesikrini (PPM). Esi sisombululo sihlangabezane neemfuno zemarike, sikhule kwimveliso, kwaye asinyusi kakhulu iindleko zizonke.
Umzobo 3. Umzobo wesicwangciso senkqubo yokwaleka komhlaba
Ukongezelela, inkqubo yokukhusela ngasemva kwe-PCB (iBhodi yeSekethe eShicileleyo) igcina indlela yokukhusela i-paint-proof yangaphambili, iphucula izinga lokukhusela ngasemva kwebhodi yesiphaluka ngokusebenzisa inkqubo yokutshiza. Uluhlu olukhuselayo lwenziwa kwisiphaluka esidibeneyo (IC), ukuthintela ukungaphumeleli kwamacandelo esekethe adibeneyo kwi-drive circuit.
3. Uhlalutyo lweempawu ze-AOB
3.1 IiPropati zoKhuseleko olubonakalayo
Iimpawu zokukhusela zomzimba ze-AOB zixhomekeke kwi-coating yokuzalisa engaphantsi, eneempawu zokubopha ezifana ne-solder paste kodwa yinto ekhuselayo. Oku kuncamathelisa okuzalisa yonke into ephantsi kwe-LED, kwandisa amandla okunxibelelana phakathi kwe-LED kunye nePCB. Uvavanyo lweLabhoratri lubonisa ukuba i-SMT yesiqhelo solder side-push amandla yi-1kg, ngelixa isisombululo se-AOB sifezekisa amandla e-side-push ye-4kg, ukuxazulula iingxaki zokungqubuzana ngexesha lofakelo kunye nokuphepha ukuchithwa kweepadi ezibangela ukuba iibhodi zezibane zingalungiseki.
3.2 Iipropati zoKhuseleko lweMichiza
Iimpawu zokukhusela iikhemikhali ze-AOB zibandakanya umaleko okhuselayo we-matte okhuselayo ofaka i-LED usebenzisa i-high-polymer material esetyenziswe ngeteknoloji ye-nanocoating. Ubunzima bolu luhlu yi-5 ~ 6H kwisikali se-Mohs, ngokuthintela ngokufanelekileyo ukufuma kunye nothuli, ukuqinisekisa ukuba amaso esibane awachatshazelwa kakubi ngokusingqongileyo ngexesha lokusetyenziswa.
3.3 Ukufunyanwa okutsha phantsi kweePropati zoKhuselo
3.3.1 Ukonyuka kweEngile yokuJonga
Umaleko okhuselayo obonakalayo we-matte usebenza njengelensi engaphambili kwe-LED, unyusa i-angle yokukhutshwa kokukhanya kweentsimbi ze-LED. Uvavanyo lubonisa ukuba i-angle yokukhutshwa kokukhanya inokunyuswa ukusuka kwi-140 ° ukuya kwi-170 °.
3.3.2 UkuPhuculwa koKuxutywa kokukhanya
Izixhobo ezixhonywe kumphezulu we-SMD ziyimithombo yokukhanya kwengongoma, eziziigranular ngakumbi xa kuthelekiswa nemithombo yokukhanya komphezulu. Ukugquma kwe-AOB yongeza umaleko weglasi ecacileyo kwii-SMD ze-LED, ukunciphisa i-granularity ngokubonakalisa kunye ne-refraction, ukunciphisa iziphumo ze-moiré, kunye nokuphucula ukuxuba ukukhanya.
3.3.3 Isikrini esiMnyama esingaguqukiyo
Imibala ye-inki yebhodi yePCB engahambelaniyo ibisoloko iyingxaki kwiziboniso ze-SMD. Itekhnoloji yokwaleka ye-AOB inokulawula ubukhulu kunye nombala womaleko wokugquma, ukusombulula ngempumelelo umba wemibala ye-inki ye-PCB engahambelaniyo ngaphandle kokulahlekelwa zii-engile zokubukela, ijongane ngokugqibeleleyo nomba wokusetyenziswa kweebhetshi ezahlukeneyo zeebhodi zePCB kunye, kunye nokuphucula ukusebenza kakuhle kokuthunyelwa.
3.3.4 Ukwandiswa kokuchasana
I-Nanocoating ivumela ulawulo oluchanekileyo, kunye nokwakheka kwezinto ezilawulekayo, ukwandisa ubumnyama bombala wesiseko sesikrini kunye nokuphucula umahluko.
4. Isiphelo
Itekhnoloji yokugquma i-AOB ifaka izikhonkwane ezivezwayo zombane, zikhusela ngokufanelekileyo iimpazamo ezibangelwa ngumswakama kunye nothuli, ngelixa zibonelela ngokhuseleko lokungqubana. Ngokukhuselwa kodwa kwe-AOB nanocoating, amazinga e-LED angancitshiswa abe ngaphantsi kwe-5PPM, ukuphucula kakhulu isivuno sesikrini kunye nokuthembeka.
Eyakhelwe kwisiseko sokubonisa i-SMD ye-LED, inkqubo ye-AOB izuza inzuzo yokugcinwa kwesibane esisodwa se-SMD, ngelixa ukulungiswa ngokupheleleyo kunye nokuphucula imiphumo yokusetyenziswa komsebenzisi kunye nokuthembeka ngokubhekiselele kumswakama, uthuli, izinga lokukhusela, kunye nezinga lokukhanya elifile. Ukuvela kwe-AOB kunika i-premium yokukhetha izisombululo zokubonisa zangaphakathi kwaye yinto ebalulekileyo ekuguqukeni kweteknoloji yokubonisa i-LED.
I-RTLED entsha yobungqina obuphindwe kathathu ngaphakathiUmboniso omncinci we-LED– ungangeni manzi, ungangenwa luthuli kwaye ungangqubani – i-AOB Display.Qhagamshelana nathi ngokuukufumana iquota esemthethweni.
