Ngawaphi amacandelo aphambili esikrini esikhokelelweyo somboniso?Kukho abavelisi abaninzi be-LED kwimarike, kwaye ixabiso lohlobo olufanayo lwe-LED lisahluke kakhulu.Inxalenye enkulu yesizathu ilele kumacandelo ayo.Umgangatho kunye nexabiso leyunithi yala macandelo okwakhiwa kuya kuchaphazela ixabiso lokugqibela lomboniso we-LED.Silandele namhlanje Makhe sijonge amacandelo omboniso okhokelwayo:
1. Ibhodi yeyunithi
Ibhodi yeyunithi yenye yezinto eziphambili zomboniso okhokelwayo.Umgangatho webhodi yeyunithi uya kuchaphazela ngokuthe ngqo umphumo wokubonisa umboniso okhokelwayo.Ibhodi yeyunithi yenziwe yimodyuli ekhokelwayo, i-chip yomqhubi kunye nebhodi yesekethe ye-pcb.Imodyuli ekhokelwayo ngokwenene iqulunqwe ngabaninzi Indawo yokukhanya ye-LED ifakwe kwi-resin okanye iplastiki;
Itshiphu yomqhubi yi-74HC59574HC245/24474HC1384953.
Iimpawu zebhodi yeyunithi ezisetyenziswa ngokuqhelekileyo kwizikrini ze-LED zangaphakathi zezi:
Ipharamitha D=3.75;i-dot pitch 4.75mm, ububanzi bechaphaza * 16 dot ukuphakama, 1/16 tshayela ukukhanya kwangaphakathi, enye ebomvu / ebomvu kunye nemibala emibini eluhlaza;
Inkcazo yeParameter
I-D imele ubukhulu obukhanyayo, obubhekiselele kububanzi bendawo ekhanyayo D = 3.75mm;
Umgama wokukhanya okhupha ukukhanya ngu-4.75mm, ngokomgama wokubukela womsebenzisi, indawo yangaphakathi ikhetha ngokubanzi i-4.75;
Ubungakanani bebhodi yeyunithi yi-64 * 16, eyibhodi yeyunithi esetyenziswa ngokuqhelekileyo, ekulula ukuyithenga kwaye ixabiso lincinci;
I-1/16 yokutshayela, indlela yokulawula ibhodi yeyunithi;
Ukukhanya kwangaphakathi kubhekisela ekukhanyeni kwesibane sokukhanyisa ukukhanya kwe-LED, kunye nokukhanya kwangaphakathi kuhambelana nokusingqongileyo ekufuneka kukhanyiswe ngezibane ze-fluorescent emini;
Umbala, umbala omnye usetyenziswa ngokuqhelekileyo, kwaye ixabiso lincinci, imibala emibini ngokubanzi ibhekisela kubomvu kunye nohlaza, kwaye ixabiso liya kuba phezulu kancinane;
Masithi ufuna ukwenza isikrini se-128 * 16, vele udibanise iibhodi zeeyunithi ezimbini kuthotho;
2. Amandla
Ngokuqhelekileyo, ukunikezelwa kwamandla okutshintsha kusetyenziswa, igalelo le-220v, i-5v ye-DC output, kodwa kufuneka kuqatshelwe apha ukuba ngenxa yokuba umboniso okhokelwayo sisixhobo sombane esiphucukileyo, kuyimfuneko ukusebenzisa unikezelo lwamandla okutshintsha endaweni ye-transformer.Ngomnye obomvu wangaphakathi 64 * 16 Xa ibhodi yeyunithi ikhanya ngokupheleleyo, okwangoku yi-2a;inokuthi ifakwe ukuba i-current ye-128 * 16 isikrini esinemibala emibini i-8a kwisimo esiqaqambileyo, kwaye i-5v10a yokutshintsha umbane kufuneka ikhethwe;
3. Ikhadi lokulawula
Sincoma ukusebenzisa ikhadi eliphantsi lokulawula isikrini se-strip strip, elinokulawula isikrini se-256 * 16-dot yemibala emibini kunye ne-1/16 scan, kwaye inokudibanisa isikrini se-LED ngenzuzo ephezulu yeendleko.Ikhadi lokulawula likhadi le-asynchronous, oko kukuthi, Ikhadi linokugcina ulwazi emva kokucima umbane, kwaye lingabonisa ulwazi olugcinwe kuyo ngaphandle kokuxhuma kwikhompyutheni.Xa uthenga ibhodi yeyunithi, kufuneka udibane neeparamitha.Ibhodi yeyunithi ehambelana ngokupheleleyo ubukhulu becala ine-interface ye-08, umgama we-4.75mm point, amanqaku angama-64 ububanzi kunye ne-16 amanqaku aphezulu., 1/16 scan ukukhanya kwangaphakathi, enye ebomvu / ebomvu kunye nemibala emibini eluhlaza;08 interface 7.62mm point umgama amanqaku 64 ububanzi * 16 amanqaku aphezulu, 1/16 scan ukukhanya kwangaphakathi, enye ebomvu / ebomvu kunye nemibala emibini eluhlaza;08 ujongano 7.62 amanqaku umgama 64 amanqaku Ububanzi * 16 amanqaku ukuphakama, 1/16 isiqingatha-tshayela ukukhanya ngaphandle, enye ebomvu / ebomvu kunye eluhlaza ezimbini-umbala;
4. Malunga ne-16PIN08 interface
Ngenxa yokuba baninzi abavelisi beebhodi zeeyunithi kunye namakhadi okulawula, zininzi iindlela zokujonga ibhodi yeyunithi.Xa uhlanganisa isikrini se-LED, kuyimfuneko ukuqinisekisa ukuhambelana kwe-interface ukuququzelela indibano.Apha sazisa ujongano lwe-LED olusetyenziswa ngokuqhelekileyo: inombolo ye-LED ye-LED: i-interface ye-16PIN08, ulandelelwano lojongano ngolu hlobo lulandelayo: 2ABCDG1G2STBCLK16
1NNNENR1R2NN15
I-ABCD sisignali yokukhetha umqolo, i-STB sisignali ye-latch, i-CLK sisignali yewotshi, i-R1, i-R2, i-G1, i-G2 yidatha yokubonisa, i-EN ngumsebenzi wokubonisa, kunye no-N ngumhlaba.Qinisekisa ukuba i-interface phakathi kwebhodi yeyunithi kunye nekhadi lokulawula iyafana kwaye inokudibaniswa ngokuthe ngqo Ukuba ayihambelani, kufuneka wenze umgca wokuguqula ngokwakho ukuguqula umyalelo wemigca;
5. Umgca wokudibanisa
Ukwahlulwe kakhulu kumgca wedatha, umgca wokuhambisa, umgca wamandla, umgca wedatha usetyenziselwa ukudibanisa ikhadi lokulawula kunye nebhodi yeyunithi ye-LED, umgca wokuhambisa usetyenziselwa ukudibanisa ikhadi lokulawula kunye nekhompyutheni, umgca wamandla usetyenziselwa ukudibanisa. ukunikezelwa kwamandla kunye nekhadi lokulawula amandla ombane kunye nebhodi yeyunithi ekhokelwayo, isiseko sobhedu somgca wamandla odibanisa ibhodi yeyunithi akufanele ibe ngaphantsi kwe-1mm ububanzi;
Ezi zingasentla ngamalungu esakhiwo somboniso we-LED ogcwele umbala.Isishwankathelo, kukho iibhodi zeeyunithi, izixhobo zombane, amakhadi okulawula, imigca yokudibanisa, njl. Ndiyathemba ukuba eli nqaku linokuba luncedo kuwe.Ukuba ufuna ukwazi ngakumbi malunga nesakhiwo solwazi lwesibonisi se-LED, wamkelekile ukuba uqhubeke nokunikela ingqalelo.
