Ubwino waukulu wa COG Technology LCD Screens

Ubwino waukulu wa COG Technology LCD Screens
Ukadaulo wa COG (Chip on Glass) umaphatikiza dalaivala IC molunjika ku gawo lapansi lagalasi, kukwaniritsa mapangidwe ophatikizika komanso opulumutsa malo, kuwapangitsa kukhala abwino kwa zida zonyamula zokhala ndi malo ochepa (mwachitsanzo, zovala, zida zamankhwala). Kudalirika kwake kwakukulu kumachokera ku kuchepetsedwa kwa malo olumikizirana, kuchepetsa chiwopsezo cha kusalumikizana bwino, komanso kupereka kukana kugwedezeka, kusokoneza pang'ono kwamagetsi (EMI), komanso kugwiritsa ntchito mphamvu pang'ono-zabwino zomwe zimayenera kugwiritsa ntchito mafakitale, magalimoto, ndi mabatire. Kuphatikiza apo, pakupanga zinthu zambiri, makina opanga makina a COG apamwamba amachepetsa kwambiri mtengo wa skrini ya LCD, ndikupangitsa kuti ikhale chisankho chokondedwa chamagetsi ogula (mwachitsanzo, zowerengera, mapanelo a zida zapanyumba).

Zolepheretsa Zazikulu za COG Technology LCD Screens
Zoyipa zaukadaulo uwu zimaphatikizapo kukonza zovuta (zowonongeka zimafunikira kusinthidwa kwathunthu), kusinthasintha kocheperako (ntchito za IC zoyendetsa zimakhazikika ndipo sizingasinthidwe), komanso zofunikira zopanga (kutengera zida zolondola ndi malo oyeretsa). Kuphatikiza apo, kusiyana kwa ma coefficients okulitsa kutentha pakati pa magalasi ndi ma IC kungayambitse kuwonongeka kwa magwiridwe antchito pansi pa kutentha kwambiri (> 70 ° C kapena <-20 ° C). Kuphatikiza apo, ma LCD ena otsika a COG omwe amagwiritsa ntchito ukadaulo wa TN amavutika ndi ma angles ocheperako komanso kusiyanitsa kochepa, zomwe zimafunikira kukhathamiritsa kwina.

Mapulogalamu Oyenera ndi Kufananitsa Kwaukadaulo
Zowonetsera za COG LCD ndizoyenera kwambiri pakupanga malo, kupanga ma voliyumu apamwamba omwe amafunikira kudalirika kwakukulu (mwachitsanzo, ma HMI a mafakitale, mapanelo anzeru apanyumba), koma samalimbikitsidwa pamapulogalamu omwe amafunikira kukonzedwa pafupipafupi, kusintha makonda ang'onoang'ono, kapena malo owopsa. Poyerekeza ndi COB (kukonza kosavuta koma kokulirapo) ndi COF (mapangidwe osinthika koma okwera mtengo), COG imayendetsa bwino pakati pa mtengo, kukula, ndi kudalirika, zomwe zimapangitsa kusankha kwakukulu kwa mawonedwe ang'onoang'ono mpaka apakatikati a LCD (mwachitsanzo, ma modules 12864). Kusankhidwa kuyenera kutengera zofunikira zenizeni komanso kusinthanitsa.
