Sida aan ognahay, bandhigga COB (Chip-on-board) wuxuu leeyahay faa'iidooyinka isbarbardhigga aadka u sarreeya, dhalaalka sare, iyo gamut midab ballaaran.
Inta lagu guda jiro horumarinta min garoon yar ilaa soo bandhigida garoonka yar, xirmada asalka ah ee SMD way adkeyd in la jebiyo xaddidaadda dhibcaha dhibcaha yar, sidoo kale way adagtahay in la dammaanad qaado isku halaynta sare iyo ilaalinta.Bandhiga cabirka-yar-yar wuxuu u baahan yahay tignoolajiyada COB si ay u taageerto horumarinta bandhiga garka yar ee pixel-ga ka yar yahay P1.0mm.
Bandhiga COB wuxuu qaataa habka baakadaha flip-chip, kaas oo leh dariiq kuleyl gaaban oo gaaban oo ku habboon kuleylka kulaylka marka la barbar dhigo bandhigga farsamada SMD ee caadiga ah.
Iyada oo qaan-gaadhnimada joogtada ah ee tignoolajiyada daaweynta dusha COB iyo tignoolajiyada isku dhafka chip, alaabada LED-ku soo bandhigaan ee isticmaalaya chips-chip-ka yar ee 100 microns waxay noqon doonaan badeecooyin bandhig rajo leh mustaqbalka.
P0.9 COB Mini/Muuqaal yar oo LED ah waa badeeco bislaaday, taas oo si ballaaran loo soo saaray
Sannadka 2019, awoodda wax-soo-saarka ballaaran ee bandhigyada ka hooseeya P0.9 ayaa weli ah mid xaddidan.Dhanka kale, baahida suuqa ayaa ah mid xadidan, awoodda taageerada silsiladda warshaduhu sidoo kale kuma filna.
Marka la gaaro 2021, iyada oo la horumarinayo tignoolajiyada baakadaha, hagaajinta hufnaanta, iyo hoos u dhaca qiimaha degdega ah ee chips LED, iwm, baahida alaabada ka hooseeya P1.0 waxay si tartiib tartiib ah u noqon doontaa suuq caan ah, iyo alaabada Mini LED sidoo kale waxay gali doontaa suuqa-dhamaadka sare ilaa suuqa dhexe-ilaa-dhamaadka sare, laga bilaabo bandhig xirfadeed ilaa bandhig ganacsi ka dibna goobta rayidka ah, waxay u beddeshay tallaabo tallaabo.
By 2022, marka la eego qaabka baakadaha, haddii ay tahay COB, afar-in-hal, ama laba-in-hal, dhib maaha sahayda qalabka P0.9mm diode, iyo awoodda wax soo saarka iyo wax-soo-saarka labadaba waxay noqon karaan dammaanad qaaday.
Si kastaba ha ahaatee, sababo la xiriira qiimaha, laga bilaabo suuqa yar ee hadda jira, suuqa wax soo saarka ee P0.9 ayaa weli ku urursan shirarka qaarkood, maamulka iyo kormeerka qolka mashaariicda dawladda ama shirkadaha waaweyn ee dawladdu leedahay, iyo P1.2- P1.5 ayaa weli ah suuqa ugu weyn ee suuqa yar-yar..
Laakiin xaaladdan ayaa soo hagaagaysa, iyo xaaladaha codsiga ee P0.9 Mini wax soo saarka tooska ah ayaa si joogto ah u kordhaya.
Garoonka ku wareegsan bandhiga P0.7 LED wuxuu noqon doonaa jiilka soo socda ee caadiga ah.
P0.7mm waxay heli kartaa 4K xallinta 100-200 inji
Cabbirka u dhexeeya 100-200 inji waa suuq cusub oo arji oo suurtagal ah oo loogu talagalay bandhigyada garoonnada yaryar.
Sababtoo ah suuqa ka sarreeya 200 inji waxaa horeyba u qabsaday P1.2 ~ 2.5mm bandhigyo yaryar oo LED ah, cabbirka wax yarna waa inta badan 98-inch LCD TV alaabta, qiimaha ugu yar ee hadda waa wax ka yar 3,000 USD, iyo bandhigga Saameyntu sidoo kale waa mid wanaagsan.Muuqaalka wanaagsan ee LED-ka waa ay adagtahay in lagula tartamo LCD suuqa 98-inch.
Si kastaba ha ahaatee, cabbirka muujinta shaashadda LCD way adag tahay in la jebiyo xadka 100-inch.Tartamayaasha dhaqameed ee bandhigyada 100-200-inch ayaa inta badan ah bandhigyo saadaalin ah - si kastaba ha ahaatee, shaashadaha waaweyn ee LED-ka ee wanaagsan ayaa leh waxqabad muuqaal ah oo ka wanaagsan "xaaladaha iftiinka."
Inta badan suuqyada 100-200-inch waxaa ka mid ah qolalka shirarka, ganacsiga, xayaysiinta, iyo xaaladaha kale, kuwaas oo u baahan xaalado iftiin wanaagsan.
Iyo suuqa 100-200 inch, bandhigyada LED-yada yaryar waxay sidoo kale wajahayaan baahida loo qabo isbarbardhigga xallinta PPI iyo bandhigyada LCD.
Sababtoo ah codsiga 100-200-inch wuxuu u dhigmaa masaafada ugu dhow ee daawashada 3-7 mitir, ama xitaa fogaanta daawashada dhow.Fogaanta dhow ee daawashada waxay hubisaa saamaynta tayada sawirka, laakiin sidoo kale waxay u baahan tahay "xallinta PPI sare", taas oo ah, waxay u baahan tahay garoon yar oo pixel ah.
Si fudud loo dhigo, 75-98-inji LCD-yada waxay hore u gaareen xallinta 4K;xallinta 100+ muraayadaha sare ee LED-yada ma noqon karaan kuwo aad u xun.
Tilmaamaha P0.7 wuxuu ku siin karaa xallinta 4K ee 120-inch +, taas oo ah xallinta codsiyada maqal-muuqaalka caadiga ah ee hadda jira oo ka weyn 98-inch LCD.
Marka tan la eego, isbarbardhigi waa in heerka pixel-ka ee hadda jira ee TV-yada LCD-ga caadiga ah uu u dhexeeyo 0.3 iyo 0.57 mm.Waxaa la arki karaa in fogaanta shaashadda LED-yar ee P0.7 mm ay si fiican ugu xiri karto khibradda codsiga ee kormeerayaasha LCD, oo ay bixiso alaabooyin kala duwan oo cabbirro waaweyn oo 100-200 ah.
Sidaa darteed, laga soo bilaabo baahida suuqa ee cabbirka iyo xallinta, waxaa la arki karaa in P0.7 ay noqon doonto jiilka soo socda ee tilmaamayaasha muraayadaha LED-ga yar.
Laakiin horumarinta P0.7 100-200 inch suuqa soo bandhigay waxay u baahan tahay qiimo ka sii wanaagsan hadda.Marka la eego, LED-yada yaryar ee yaryar ayaa sii kordhaya natiijooyinka iyada oo loo marayo ururinta joogtada ah ee waayo-aragnimada iyo horumarinta habka wax soo saarka si tartiib tartiib ah.Gaar ahaan saddexdii sano ee la soo dhaafay, alaabada P0.9 waxay ku guuleysteen guul gaar ah suuqa-dhamaadka sare, qiimuhuna wuxuu hoos u dhacay ilaa 30%.Falanqeeyayaasha warshadaha ayaa rumeysan in alaabada P0.7 la filayo inay la mid noqdaan alaabtii P0.9 ee hore.
Warshaduhu waxay filayaan in labada sano ee soo socota, silsiladda warshadaha kor u kaca ee bandhigyada LED oo ay ku jiraan chips-yar oo LED ah, iwm, si weyn loo wanaajin doono, iyo heerka tignoolajiyada wax soo saarka iyo habka wax soo saarka ayaa sidoo kale si weyn loo horumarin doonaa.Suuqa warshadaha ayaa wajahaya wareeg ah Suurtagalnimada dhimista qiimaha.Tani sidoo kale waa "waqti wanaagsan" qaabeynta jiilka cusub ee "P0.7 pitch" alaabta.
Codsiga 100-200-inch waa "xaalad cusub" oo caadi ah oo tijaabisa tignoolajiyada warshadaha iyo xakamaynta qiimaha.
Dabcan, shirkado kala duwan ayaa sidoo kale samayn doona hagaajin si ay u muujiyaan faa'iidooyinka alaabtooda: tusaale ahaan, si loo yareeyo kharashyada iyo dhibaatooyinka, wax-soo-saarayaashu waxay ku siin karaan 136-inch 4K alaabooyin leh garoon yar oo pixel ah;ama u bixi xallinta 4K alaabta cabbirka yar, sida Samsung The Wall wuxuu isticmaalaa garoon 0.63mm ah.
Waa maxay caqabadaha soo bandhigida garoonka P0.7?
Qarash sare
Ka hore waa kharash.Laakiin maaha caqabadda ugu weyn.
Tani waa sababta oo ah P0.7mm waa inay noqotaa bandhig heer sare ah, waana macaamiisha kuwaas oo u baahan waxqabadka mudnaanta.Tani waxay la mid tahay jiil kasta oo ka mid ah alaabooyinka LED-yada yaryar ee "la gooyey suuqa-dhamaadka sare" oo si dhakhso ah u helaya aqoonsiga suuqa.Marka laga eego dhinaca kharashka, maaha mid aad u adag in bandhigyada P0.7 ay bilaabaan ballaarinta suuqa-dhamaadka sare bilowga.
Farsamada wax soo saarka ee aan qaan-gaarin
Marka la barbardhigo P1.0, tirada qaybaha halbeegga bandhiga ee P0.7 waa labanlaab.Si kastaba ha noqotee, inkasta oo ay suurtagal tahay in la dhaxlo khibradda farsamada ee ay ururiyeen alaabtii hore ee P0.9-P1.0, waxay sidoo kale u baahan tahay caqabado cusub oo dhibaatooyin aan la garanayn.Warshadaha ayaa weli ku jira marxaladda hore ee tignoolajiyada qaan-gaarka ah si ay si dhab ah u soo saaraan wax soo saarka P0.7mm.
Garoomo yar oo kala duwan, heer ma jiro
Marka lagu daro kharashka iyo habka wax soo saarka caqabadaha farsamada, caqabad kale oo ku saabsan alaabta P0.7 ayaa ah in kala fogaantu ay adagtahay in la qiyaaso.
Codsiga 100-200-inji inta badan waa "all-in-one screen" halkii mashruuc kala qaybin, taas oo macnaheedu yahay in shirkadaha waaweyn ee LED waxay u baahan yihiin inay helaan "shuruudaha cabbirka codsiga" ee caadiga ah oo ay ku daraan awoodaha farsamada samee wax la mid ah: xallinta 4K, 120 inch, 150 inches, 180 inches, 200 inches iyo cabbirrada unugga kale ee go'an, laakiin cufnaanta pixel-ka ayaa ka duwan.
Natiijo ahaan, unugyada 110/120/130-inji ee u muuqda inay la mid yihiin waxay u baahan yihiin inay adeegsadaan "qaab-dhismeedka tignoolajiyada hab-socod la isku hagaajin karo" kaas oo ku beddelma heerka garoonka P0.7.
La kulma tartan toos ah oo ka imanaya LCD-ganacsiga dhaqameed ama alaab-qeybiyeyaasha saadaasha
Intaa waxaa dheer, suuqa soo bandhigida LED-yada micro-pitch ee u dhexeeya 100-200 inches, shirkadaha yaryar ee muraayadaha LED waxay sidoo kale u baahan yihiin inay la kulmaan caqabadaha tartanka shirkadaha isticmaala muraayadaha ganacsiga LCD ee caadiga ah sida alaabtooda.
Suuqyadii hore ee yar-yar ee LED-yada, shirkadaha waaweyn ee muraayadaha LED waxay la tartamayeen asaagooda, laakiin hadda waxay u baahan yihiin inay ballaariyaan baaxadda tartanka ilaa dhammaan suuqyada bandhigga ganacsiga.Xitaa waa inay la kulantaa cadaadiska tartanka TFT-MINI / MICOR LED ee ay bilaabeen BOE iyo Huaxing Optoelectronics.
