muuqaal wanaagsan oo LED ah

Hal-abuurnimada joogtada ah ee tignoolajiyada soo bandhigista LED waxay noo ogolaanaysaa inaan markhaati ka noqonno dhalashada bandhigga fican ee LED. Laakiin waa maxay dhab ahaantii bandhigga LED-ga wanaagsan? Marka la soo koobo, waa nooc ka mid ah bandhigga LED-ka iyadoo la adeegsanayo tignoolajiyada ugu horumarsan, oo leh cufnaanta pixel aadka u sarreeya iyo waxqabadka midab aad u wanaagsan, taasoo kuu oggolaaneysa inaad ku dhex gasho xafladda muuqaalka ah ee qeexitaan sare iyo midabyo dhalaalaya. Marka xigta, maqaalkani wuxuu ka wada hadli doonaa mabaadi'da farsamada, aagagga codsiga iyo isbeddellada horumarinta mustaqbalka ee bandhigga wanaagsan ee LED-ka, oo kuu keenaya inaad ku raaxaysato adduunka cajiibka ah ee bandhigga LED!

2. Fahamka farsamada asaasiga ah ee bandhigyada LED-ga-fiican

2.1 Qeexitaan Fine Pitch

Muuqaalka LED-ka ee fican, sida magacaba ka muuqata, waa nooc ka mid ah muraayadda LED-ka oo leh pixel pitch oo aad u yar, kaas oo lagu garto masaafada u dhaxaysa pixels oo aad ugu dhow in isha aadamuhu aanay kala saari karin pixels-ka LED-ka ee gaarka ah marka meel fog laga eego. sidaas darteed soo bandhigaya saameyn muuqaal ah oo jilicsan oo cad. Marka la barbar dhigo bandhigyada LED-yada ee dhaqameed, bandhigyada wanaagsan ee LED-yada waxay leeyihiin boob tayo leh cufnaanta pixel iyo xallinta, taas oo u oggolaanaysa caddayn sare iyo waxqabadka midabka runta ah.

2.2 Waa maxay P-qiimaha (Pixel Pitch)

P-qiimaha, ie pixel pitch, waa mid ka mid ah tusmooyinka muhiimka ah si loo cabbiro cufnaanta pixel ee bandhiga LED. Waxay ka dhigan tahay masaafada u dhaxaysa labada pixels ee deriska ah, oo badanaa lagu qiyaaso millimitir (mm.) P-qiimaha yar, inta yar ee masaafada u dhaxaysa pixels, sare ee cufnaanta pixel, oo sidaas daraaddeed bay u caddahay. Bandhigyada Fiican ee LED-yada waxay inta badan leeyihiin qiime yar oo P- ah, sida P2.5, P1.9 ama xitaa ka yar, taas oo macnaheedu yahay inay awoodaan inay ogaadaan pixels badan oo ku yaal aag muuqaal yar, oo soo bandhigaya muuqaal xallin sare.

2.3 Heerarka Pitch Fine (P2.5 iyo wixii ka hooseeya)

Guud ahaan, halbeegga loogu talagalay bandhigyada garoonnada wanaagsan ee LED waa P-qiimaha 2.5 iyo ka hooseeya. Tani waxay ka dhigan tahay in farqiga u dhexeeya pixels uu yahay mid aad u yar, kaas oo ogaan kara cufnaanta sare ee pixel iyo saamaynta bandhigga xallinta sare. Inta yar ee qiimaha P waa, sare u kaca cufnaanta pixel ee muraayadda fiilada LED-ka, iyo sida ugu wanaagsan ee saamaynta bandhiggu noqon doonto.

3. Tilmaamaha Farsamada

3.1 Xallinta sare

Bandhiga LED-ga ee wanaagsan wuxuu leeyahay cufnaanta pixel aad u sarreeya, kaas oo soo bandhigi kara pixels badan booska shaashadda xaddidan, sidaas darteed garashada xallinta sare. Tani waxay u keentaa isticmaalaha tafaasiil fiiqan iyo sawiro waaqici ah.

3.2 Heerka Soo Celinta Sare

Bandhigyada Fiican ee LED waxay leeyihiin qiime cusub oo degdeg ah, oo awood u leh inay cusboonaysiiyaan nuxurka sawirka tobanaan ama xitaa boqolaal jeer ilbiriqsikii. Heerarka dib-u-cusboonaysiinta sare waxay ka dhigan tahay sawir fudud, kaas oo yaraynaya sawirka gilgisha iyo liidashada, oo soo bandhigaysa waayo-aragnimo muuqaal ah oo raaxo leh ee daawadayaasha.

3.3 Iftiinka Sare iyo Isbarbardhigga

Bandhigyada fican ee LED waxay bixiyaan dhalaal sare iyo isbarbardhig sare, xitaa jawiyo dhalaalaya. Hadday tahay gudaha iyo dibaddaba, caddaynta iyo hufnaanta sawirka waa la ilaalin karaa, iyadoo la siinayo waxqabad wanaagsan oo loogu talagalay bandhigyada xayaysiisyada, bandhigyada marxaladda iyo munaasabadaha kale.

3.4 Midabka joogteynta iyo taranka

Muujinta Fine-pitch LED waxay leedahay joogteynta midabka iyo midabaynta midabka, taas oo si sax ah u soo celin karta midabka sawirka asalka ah. Hadday tahay casaan, cagaar ama buluug, waxay ilaalin kartaa midab isku mid ah iyo dharbaaxo.

4. Habka wax soo saarka ee

4.1 Soosaarka Chip

Xudunta u ah bandhiga fican ee LED waa chip-ka LED-ga oo tayo sare leh, Chip-ka LED-ku waa unugga iftiimiya iftiinka, kaas oo go'aamiya dhalaalka, midabka iyo nolosha shaashadda. Habka wax-soo-saarka chip-ka waxaa ka mid ah kobaca epitaxial, soo saarista jajabka iyo tillaabooyinka tijaabada.

Walaxda LED-ku waxay ku samaysmaan substrate-ka iyada oo loo marayo tignoolajiyada koritaanka epitaxial ka dibna la gooyaa jajabyo yaryar. Habka samaynta chip-ka tayada sare leh waxay hubisaa in chips-ka LED-ku leeyahay dhalaal sare iyo nolol dheer.

4.2 Tignoolajiyada Baakadaha

Chips-ka LED-ka waxa kaliya oo si wax ku ool ah loo ilaalin karaa oo la isticmaali karaa ka dib marka la duubo. Geedi socodka xifdinta waxay ku lug leedahay hagaajinta chip LED on bracket iyo in kaabsulate la epoxy resin ama silikoon si ay u ilaaliyaan chip ka deegaanka dibadda. Tiknoolajiyada kor u kaca ee kor u kaca waxay hagaajin kartaa waxqabadka kulaylka iyo isku halaynta chips LED, sidaas darteed kordhinta nolosha adeegga bandhigga. Intaa waxaa dheer, bandhigyada wanaagsan ee LED-yada waxay inta badan isticmaalaan tignoolajiyada korka sare (SMD) si ay ugu soo koobaan LED-yo yaryar oo badan oo hal unug ah si loo gaaro cufnaanta sare ee pixel iyo saameyn muuqaal wanaagsan.

4.3 Qaybinta Module

Bandhiga LED-ga fiican wuxuu ka kooban yahay qaybo badan oo LED ah oo la isku daray, cutub kastaa waa unug bandhig madax bannaan. Saxnaanta iyo joogtaynta qaybinta cutubka ayaa saameyn muhiim ah ku leh saameynta soo bandhigida ugu dambeysa. Habka kala qaybinta moduleka saxda ah ee saxda ah wuxuu xaqiijin karaa fidsanaanta bandhigga iyo isku xirka aan kala go 'lahayn, si loo xaqiijiyo waxqabad sawir oo dhammaystiran oo siman. Intaa waxaa dheer, qaybinta moduleka waxay sidoo kale ku lug leedahay naqshadeynta isku xirka korantada iyo gudbinta calaamadaha si loo hubiyo in module kasta uu si wadajir ah u shaqeyn karo si loo gaaro waxqabadka ugu fiican ee bandhigga guud.
