Nkag siab COB, Huab, thiab COG hauv LCD ntxaij
Hauv qhov tseeb ntawm LCD cov ntxaij vab tshaus, acronyms zoo li COB, Huab, thiab COG feem ntau ntsib, txhua tus sawv cev ntawm qhov tseem ceeb ntawm cov duab thev naus laus zis.
Cia peb delve rau hauv dab tsi cov ntsiab lus ntawd tau hais txog:
1. Cob -}}- ntawm {{3} board
COB, lossis nti {-- board, yog cov thev naus laus zis slicionductor chips yog ncaj qha rau hauv ib substrate.
Hauv cov ntsiab lus ntawm LCD cov ntxaij vab tshaus, COB yog hais txog kev sib khi ntawm cov kab mob ICS (sib xyaw ua ke) ncaj qha rau lub khob substrate ntawm cov zaub.
Qhov kev sib xyaw ua ke no, txo cov naj npawb ntawm cov kev sib txuas sab nraud, thiab feem ntau ua rau muaj tus nqi ntau dua li ntawm -}}}} kev daws teeb meem. COB thev naus laus zis pom ib qho kev siv me me- LCDs me me, xws li cov neeg ua haujlwm hauv saib, lub laij lej, thiab lwm cov khoom siv nqa khoom.
2. Huab {{- zaj duab xis -- iav
Huab, lossis yeeb yaj kiab -}- Imm, yog cov iav, yog lub khob tranitor (TFT) ncaj qha rau ntawm lub khob substrate ntawm LCD. Lub tft array yog tsim ncaj qha rau ntawm iav saum npoo av, ua kom tau zoo dua cov duab zoo thiab teb cov sijhawm. Huab thev naus laus zis yog nthuav dav nyob rau hauv loj- lpds loj, tshwj xeeb cov siv hauv TV thiab cov saib xyuas computer. Nws pab txhawb kom txhim kho cov xim me me, saib cov ces kaum, thiab kev daws teeb meem siab dua, ua rau nws nce mus ntxiv hauv cov duab thev naus laus zis.
3. Cog -}}- ntawm {{3} iav
Cog, lossis nti {-}- iav, yog cov iav, yog cov thev naus laus zis uas sib xyaw cov yam ntxwv thiab huab. Hauv cog qoob loo, tus tsav ICS tau ncaj qha rau ntawm lub khob substrate, zoo ib yam li COG, tab sis nrog rau kev sib koom ua ke ntxiv ntawm nyias- nkauj) ntawm tib lub iav, akin kom pos. COG thev naus laus zis tau ua haujlwm ntau hauv LCD, muab cov txiaj ntsig zoo xws li kev tsim kho, txo cov hluav taws xob kom yooj yim, thiab txhim kho cov kev ua tau zoo. Nws yog feem ntau pom hauv kev lag luam tawm, khoom siv kho mob, thiab lwm yam kev xav tau kom muaj qhov sib npaug ntawm qhov loj me, kev ua tau zoo, thiab cov duab zoo.
Hauv cov ntsiab lus, cov ntawv no sawv cev ntawm cov tshuab sib txawv ntawm cov toj roob hauv pes ntawm LCD ntxaij.
COB tsom rau kev sib xyaw ua ke ICS ncaj qha rau ntawm lub qab teb, thiab cog lus sib txuam ntawm ob qho tib si, tawm tsam qhov sib npaug ntawm kev sib txuas thiab ua yeeb yam. Nkag siab cov thev naus laus zis muab kev pom rau hauv cov ntawv thov sib txawv thiab nce qib hauv LCD zaub kev lag luam.
