Yuav ua li cas xaiv ntawm LED / COB / GOB zaub? Kev sib piv ntawm LED / COB / GOB zaub
GOB (Glass On Board), COB (Chip On Board), thiab cov ntxaij vab tshaus LED ib txwm muaj qhov sib txawv hauv cov txheej txheem ntim khoom, cov qauv txheej txheem, cov teeb pom kev zoo, thiab daim ntawv thov scenarios. Hauv qab no yog cov ncauj lus kom ntxaws sib piv:
1. Kev ntim khoom
Ib txwm LED Screen
Siv SMD (Nto Mounted Device) ntim tshuab, encapsulating LED chips nyob rau hauv ib tug neeg LED hlaws, uas yog ces soldered rau lub PCB board siv nto mount technology.
COB Screen
Directly encapsulates LED chips ntawm PCB board, tshem tawm qhov xav tau rau ib tug neeg LED hlaws dai. Cov chips txuas ncaj qha mus rau PCB board siv flip-chip lossis nto mounting txheej txheem, thiab tom qab ntawd tag nrho cov kev sib dhos tau ntim rau kev tiv thaiv.
GOB Screen
Ua raws li SMD ntim los ntawm kev ntxiv cov iav pob tshab los yog cov txheej txheem tiv thaiv, npog tag nrho saum npoo ntawm LED hlaws los tsim cov qauv sib koom ua ke.
2. Txoj Cai
Ib txwm LED Screen
Relies ntawm qhov taw tes lub teeb qhov chaw yam ntxwv ntawm tus kheej LED hlaws. Lub cev sib txawv nyob nruab nrab ntawm cov hlaws LED, uas ua rau muaj qhov txwv pixel ceev thiab lub suab pixel loj.
COB Screen
Siv cov thev naus laus zis thev naus laus zis thev naus laus zis, cov chips LED tau ncaj qha mus rau PCB pawg thawj coj saib, tshem tawm lub cev qhov tsis sib xws ntawm LEDs thiab ua rau ultra-me me pixel suab (piv txwv li, hauv qab P0.5), ua rau cov duab zoo dua.
GOB Screen
Los ntawm kev ntxiv txheej tiv thaiv rau saum npoo ntawm SMD LEDs, txawm hais tias tseem yog qhov chaw teeb pom kev zoo, txheej txheej tiv thaiv ua kom pom kev ua haujlwm zoo, xws li kev txhim kho qhov sib piv thiab kev tiv thaiv.
3. Zaub nyhuv
Ib txwm LED Screen
Qhov zoo: cov cuab yeej paub tab, tus nqi qis, tsim nyog rau nruab nrab mus rau qhov loj pixel pitch daim ntaub ntawv.
Disadvantages: Tsawg pixel ceev, nquag mus graininess thaum saib nyob ze; Qhov sib txawv ntawm LEDs tuaj yeem tsim cov kab tsaus lossis ci.
COB Screen
Qhov zoo: Seamless splicing, siab duab uniformity, zoo xim luam; dav saib lub kaum ntse ntse (ze li 180 degree); muaj zog tiv thaiv (dustproof, waterproof, impact-resistant).
Disadvantages: tus nqi siab dua, kev kho mob nyuaj dua (yuav tsum tau ua kom tiav module hloov).
GOB Screen
Qhov zoo: Kev tiv thaiv zoo dua piv rau cov ntxaij vab tshaus LED; siab tawv hardness thiab khawb kuj; txhim kho qhov sib txawv thiab xim sib xws los ntawm cov txheej txheem tiv thaiv.
Qhov tsis zoo: Pixel ceev thiab qhov sib xws tseem txwv los ntawm SMD LED qauv, ua rau nws nyuaj rau kev ua tiav ultra- suab me me.
4. Daim ntawv thov Scenarios
Ib txwm LED Screen
Haum rau nruab nrab mus rau qhov loj qhov xwm txheej, xws li kev tshaj tawm sab nraum zoov, theem backdrops, thiab chaw ntau pob.
COB Screen
Tsim nyog rau ultra- cov xwm txheej me me, xws li siab- chav sib tham kawg, chaw tswj hwm, chaw ua lag luam, thiab tsev ua yeeb yam.
GOB Screen
Haum rau cov xwm txheej uas yuav tsum muaj kev tiv thaiv siab, xws li kev thauj mus los rau pej xeem, tsev kawm ntawv, thiab khw muag khoom.
5. Tus nqi thiab kev tu
Ib txwm LED Screen
Tus nqi qis dua thiab kev saib xyuas yooj yim (LEDs tuaj yeem hloov tau tus kheej).
COB Screen
Tus nqi siab dua thiab kev saib xyuas nyuaj (xav tau cov neeg ua haujlwm tshaj lij los hloov cov qauv).
GOB Screen
Tus nqi nruab nrab ntawm cov ntxaij vab tshaus LED thiab COB cov ntxaij vab tshaus; kev saib xyuas yooj yim (cov txheej txheem tiv thaiv txo qhov kev pheej hmoo ntawm LED puas).
6. Kev tiv thaiv kev ua haujlwm
Ib txwm LED Screen
Kev tiv thaiv tsis muaj zog; LED chips raug cuam tshuam rau lub cev los yog ib puag ncig yam.
COB Screen
Kev tiv thaiv zoo tshaj plaws; siab hardness; cuam tshuam -resistant, waterproof, thiab plua plav.
GOB Screen
Kev tiv thaiv kev ua haujlwm zoo dua li cov ntxaij vab tshaus LED, tab sis tsis muaj zog dua li cov ntxaij vab tshaus COB; cov txheej tiv thaiv nto txhim kho khawb tsis kam thiab noo noo tsis kam.
Cov lus pom zoo xaiv
Rau cov neeg nrhiav qhov zoo tshaj plaws duab zoo thiab kev tiv thaiv: Xaiv lub COB screen.
Rau cov uas xav tau tus nqi siab -kev ua tau zoo thiab kev tiv thaiv nruab nrab: Xaiv lub vijtsam GOB.
Rau cov neeg siv nyiaj tsawg thiab cov ntawv thov qhov twg pixel ceev yuav tsum tsis siab: Xaiv ib qho screen LED.
Los ntawm kev sib piv saum toj no, koj tuaj yeem xaiv cov cuab yeej tsim nyog tshaj plaws raws li koj qhov kev xav tau tshwj xeeb thiab daim ntawv thov scenarios.
