Dab tsi yog qhov txawv ntawm COB LED cov lus qhia thiab cov khoom siv coj ua LED?
Qhov sib txawv tseem ceeb ntawm COB LED cov lus qhia thiab cov khoom siv hauv LED yog raws li hauv qab no:
** Ntim Technology:**
* ** COB Technology: ** Kev sib koom ua ke LED chips ncaj qha mus rau PCB pawg thawj coj saib, tshem tawm qhov xav tau ntawm cov qauv LED hlaws sib cais. Qhov no ua kom yooj yim rau LED nti ntim txheej txheem, ua rau cov zaub nyias nyias thiab sib dua, yooj yim rau nruab thiab thauj, thiab ua kom zoo nkauj dua.
* ** SMD Technology: ** Lub tshuab paub tab uas muab cov hlaws LED rau hauv lub rooj tsavxwm. Cov thev naus laus zis no yog qhov paub tab thiab muaj cov txheej txheem tsim khoom ruaj khov, tab sis cov txheej txheem ntim khoom kuj tseem cumbersome, yuav tsum muaj qee lub sijhawm, thiab muaj kev txwv ntawm qhov tsawg kawg nkaus pixel suab, ua rau muaj kev pheej hmoo ntawm LED poob.
* **Display Effect:**
* ** COB Cov Lus Qhia: ** Tau yooj yim ua tiav me me pixel pitches, ua rau pom meej dua, cov duab ntxaws dua thiab cov xim softer. Nws muaj lub teeb zoo sib xws thiab muaj xim zoo nkauj, tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv siab - daws teeb meem duab.
* **SMD Displays:** Haum rau cov lus qhia nrog cov pixel loj dua. Nrog rau kev txhim kho thev naus laus zis, xim thiab ci ci sib xws tuaj yeem ua tau raws li qhov xav tau ntawm feem ntau cov ntawv thov scenarios. Txawm li cas los xij, cov qauv teeb pom kev zoo yuav tshwm sim thaum saib ntawm qhov ze, thiab xim thiab qhov ci ci tsis zoo yog qhov tsis zoo.
Kev ruaj ntseg thiab kev tiv thaiv
COB Cov Lus Qhia: Muab cov encapsulation zoo dua thiab kev tiv thaiv, nrog kev cuam tshuam muaj zog. Cov khoom siv tau muab ntim rau ntawm PCB pawg thawj coj saib, tiv thaiv cov teeb meem xws li LED poob lossis kev puas tsuaj thaum lub sijhawm thauj mus los, kev teeb tsa, thiab disassembly. Cov txheej txheej muab kev tiv thaiv muaj zog nrog cov tawv tawv siab, ua kom muaj kev cuam tshuam tsis zoo. Nyob rau tib lub sijhawm, qis thermal resistivity thiab siab dua cov cua kub dissipation efficiency pab ua kom ruaj khov ntev - lub sijhawm ua haujlwm.
SMD Displays: LEDs yog soldered mus rau lub rooj tsavxwm PCB, ua rau lawv yooj yim rau poob raws li qhov cuam tshuam, ua rau cov nqi kho dua. Lawv muab kev tiv thaiv qis dua thiab tsis muaj dej noo- pov thawj, tsis muaj dej, tsis muaj plua plav, tiv thaiv kev poob siab, thiab cuam tshuam- cov yam ntxwv tiv taus.
Nqi
COB Cov Lus Qhia: Thaum cov khoom loj tuaj yeem txo cov nqi ntau, qhov kev xav tau ntawm cov tshuab ntim khoom, cov nqi R & D siab, thiab cov nqi siab uas cuam tshuam nrog kev hloov pauv kev lag luam ua rau cov nqi tsim khoom muaj nqis.
SMD Displays: Mature technology nrog cov nqi tsim khoom tsawg. Txawm li cas los xij, tus nqi maj mam nce ntxiv thaum pixel suab txo qis.
Daim ntawv thov Scenario
COB Displays: Tsim nyog rau cov ntawv thov uas xav tau cov duab zoo, xws li studios, siab - chav sib tham kawg, chav tsev qhia huab cua, thiab cov khoom lag luam. Lub caij no, nws cov kev tiv thaiv zoo heev ua rau nws tshwj xeeb tshaj yog haum rau cov ntawv thov uas muaj kev hloov pauv ib puag ncig, xws li kev tshaj tawm sab nraum zoov thiab kev saib xyuas kev nyab xeeb.
SMD cov lus qhia: Tsim nyog rau tus nqi- cov ntawv thov nkag siab nrog cov kev xav tau qis dua, xws li kev tshaj tawm kev lag luam dav dav thiab cov duab hauv qab. Tsis tas li ntawd, SMD cov lus qhia muaj kev hloov pauv siab; lawv qhov loj thiab cov duab tuaj yeem hloov kho, thiab lawv tuaj yeem ua rau cov duab tshwj xeeb xws li cov nkhaus kom hloov mus rau qhov sib txawv thiab cov duab xav tau.
Hauv cov ntsiab lus, COB LED cov lus qhia muaj txiaj ntsig zoo hauv kev ua yeeb yam zoo, ruaj khov, thiab kev tiv thaiv, tab sis lawv cov nqi kuj tseem ceeb; thaum ib txwm siv SMD LED qhia ua tau zoo dua ntawm cov nqi thiab kev hloov pauv. Thaum xaiv, kev lag luam tawm - yuav tsum tau ua raws li cov kev xav tau tshwj xeeb.
