ICs difooje e LCD tokoose ina njokkondiri e laabi ɗiɗi mawɗi. Feere ndee ina doga haa yettoo teddeendi, muñal diƴƴe, muñal ɓuuɓri, mooɓondiral e feewnitagol.

Ko adii fof, ɗo mbaydiiji ɗiɗi ɗii ceerti

ICs difooje LCD tokoose ina njokkondiri e laabi ɗiɗi mawɗi. COG (chip-on-glass) ina jokkondiri e IC to bannge gilaas, ko ɗum waɗi mooɓre ndee ina famɗi no feewi kadi dogdu ummoraade e IC haa e batte gilaas ina juuti, ina addana batte laaɓtuɗe no feewi. COB (chip-on-board) ina waɗa IC e dow PCB, ina jokkondira e wire, caggal ɗuum ina ɓuuɓna ɗum e epoksi, tawa ina ɓadii alluwal gaadoraangal.

Ndeen feere ina yaaji e kala ko woni les : teddeendi, muñal diƴƴe, muñal ɓuuɓri, mooɓondiral e feewnitagol fof forko ɗoo. COG e COB ngonaa yahruɓe yeeso e ɓooyde ; ko laabi ɗiɗi karallaagal ceertuɗi, heen gooto fof ina yahdi e sarɗiiji golle ceertuɗi. Suɓo laawol ngol moƴƴaani e hay limre tuning process recover ɗum.

Doole e keeri COG

Nafoore COG ɓurnde yiyeede ko ɓuuɓri. Module ina mbaawi yahde les milimeeteeruuji ɗiɗi, ŋorol gilaas ngol ina yalta to bannge laawol, doge jokkondirɗe ina juuti, jokkondire elektoro-magnetik ina pamɗi. 1602 mbaydiiji alkule e 122x32 haa 240x128 mbaydiiji nate fof ko mawɗi, ina njogii cuɓagol gilaasi e difooje keewɗe. Kala geɗel gonngel e teddeendi e teddeendi — telefoŋaaji ɓuuɓɗi, ɓoornotooɗi, panneeji compact — ina jogii COG no jaabawol defaare.

Keeri maggal ina poti haaleede no laaɓiri. IC ina jokkondiri no feewi e gilaas, ko ɗum waɗi teskuyaaji gilaas-edge, bending e nder mooɓondiral e shock e nder yah-ngartaa fof ina mbaawi battinde e hoolaare, kadi laawol mooɓondiral ina ɗaɓɓi ɓure laaɓtuɗe. Keeri seal ina sensible e ɓuuɓri, ko ɗum waɗi hoolaare e nder nokkuuji juutɗi toowɗi ɓuuɓri ina haani peewnugol dedicated. E raɓɓiɗinaade, COG ina selli e ɓuuɓɗo e ɓuuɓɗo ; ina famɗi sehilaaɓe e sarwiis ɓuuɓɗo.

Doole e keeri COB

COB ko luutndii ɗum. IC difoowo oo ina jooɗii e dow PCB, wire-bonded e caggal ɗuum epoxy-encapsulated e nder mum, rokka laaɓndal ɓurngal moƴƴude e muñal diƴƴe e humpito, muñal mooɓondiral toowngal, e feewnitagol to bannge alluwal so huunde ŋakki. Kosam ɗam ina mawni, njoɓdi ina heewi lesɗude. 1602, 2004 haa 320x240 alkule e mbaydiiji nate ko kuutorɗe kiiɗɗe, kuutorteeɗe ko ɓuri duuɓi sappo e nder kuutorɗe e kaɓirɗe gollorɗe.

Keeri COB ko volume. Waɗde IC e dow PCB firti ko mooɓre ndee ina foti accude nokku, ko ɗuum waɗi teddeendi e nokku fof ina ummoo, ɓuuɓnude ɗum e nder weeyo milimeeteeruuji ɗiɗi walla tati ko huunde nde waawaa waɗde. Inductance ɓoggi jokkondire kadi ina famɗi no feewi e jokkondire toowɗe COG les diwgol toowngol, ko ɗum waɗi ɗum sub-optimal ngam diidi toowɗi, toowɗi-refresh. Thinness e sarɗiiji gollal — njulaagu jooɗii ko e oon mbayliigu.

Peeje tati, e Laabi ɗiɗi ɗii fof ina keddii e udditaade

Suɓngo gollorngo ina jippoo e naamne tati. Arano oo : hol to ooɗoo ekran yahrata, e no foti milimeeteeruuji ina ngoodi ngam mum — jaabawol ngol ina hollita so tawii COG ina waawi. Ɗiɗaɓere : hol nokku gollorɗo, mbele ina diwa, hol no ɓuuɓri, mbele ina feewnee — jaabawol ngol ina hollita so tawii COB ina haani. Tataɓol : njoɓdi e mbaawka — ɗiɗo fof ina mawni, ɗum noon ɗum ina famɗi ko felliti.

So ɗiin tati njaabiima, laawol ngol ina heewi laaɓtude. Heddii ko wonaa njuɓɓudi ina waawi ƴelliteede e kala yamiroore : mawneeki e resolution inɗe ɗe ngonaa njuɓɓudi ina mbaawi ƴelliteede, kadi interface, voltage logic, direction de vue, njuuteendi FPC e firooji pin fof ina mbaawi ƴeewteede e diisnondiral ngal.
