A fɔlɔ, Yɔrɔ min na o jɔcogo fila tɛ kelen ye

LCD driver IC misɛnninw bɛ siri cogo fila la minnu bɛ kɛ ka caya.

COB (chip-on-board) bɛ IC bila PCB kan, ka a siri ni nɛgɛ ye ka sɔrɔ ka a siri ni epoyi ye, a jɔcogo ka surun pankurun kɔrɔ la.

O danfara bɛ jɛnsɛn fɛn bɛɛ fɛ duguma: a bonya, a yɛrɛyɛrɛ muɲuni, a nɛnɛ muɲuni, a lajɛcogo ani a dilancogo bɛɛ bɛ foroko yan. COG ni COB tɛ ɲɛtaa ye ni kɔrɔlen ye; u ye fɛɛrɛ sira fila ye minnu tɛ kelen ye, u kelen-kelen bɛɛ bɛ bɛn baarakɛcogo wɛrɛw ma. Sira jugu sugandi ani processus tuning hakɛ si t’a lasegin.

COG ka fanga ni dancɛw

COG nafa min bɛ ye kosɛbɛ, o ye a finman ye. Modules bɛ se ka taa milimɛtɛrɛ fila duguma, gilasi da bɛ bɔ k’a ɲɛsin ɲɔgɔn ma, ɲɔgɔndan boliw ka surun ani kuran-magnetic interference ka dɔgɔn. 1602 sɛbɛnnibolow ani 122x32 fo 240x128 jatebɔcogo bɛɛ kɔgɔlen don, ni gilasi ni bolifɛnw sugandili ka ca.
