TAB (Daim kab xev Automated Bonding) & COF (Chip on Film): TAB siv daim kab xev- ntawm kev ntim tshuab rau ICs integrated circuit, haum rau cov ntawv thov uas yuav tsum tau siv qhov chaw siab thiab kev teeb tsa yooj yim. COF ncaj qha sib txuas cov nti mus rau cov yeeb yaj kiab hloov tau yooj yim, muab cov ntaub ntawv nyias nyias thiab yooj yim dua.
IV. Graphic Displays thiab Character Displays
Cov Duab Duab: Siv STN lossis FSTN thev naus laus zis, muab qhov sib txawv siab, pom dav dav, thiab ntau hom zaub. Cov duab kos duab tsim nyog rau cov ntawv thov uas xav tau cov duab thiab cov duab, xws li kev ntsuas, kev tswj hwm kev lag luam, thiab lub zog thiab kev tiv thaiv ib puag ncig.
Cov Cim Qhia: tuaj yeem tso saib cov lej, cov tsiaj ntawv, thiab lwm yam ASCII cov cim, muab ntau yam kev qhia tshwj xeeb thiab kev xaiv hloov pauv hloov pauv. Cov cim qhia tau dav siv hauv cov khoom siv hauv kev lag luam, cov khoom siv sib txuas lus, thiab cov tshuab kos.
V. Qis-Tub kub zaub Modules
Tsawg- qhov kub thiab txias zaub modules yog tsim los rau cov cheeb tsam txias heev thiab cov tub rog kev lag luam, nrog rau qis- kub LCD modules, qis- kub OLED modules, thiab siab - kev ntseeg siab tso saib modules. Cov qauv no tuaj yeem ua haujlwm ib txwm nyob ntawm qhov kub tsis tshua muaj siab, ua kom cov khoom ruaj khov thiab kev ntseeg tau.
VI. Serial Port Display Modules
Serial chaw nres nkoj zaub modules suav nrog serial LCD modules, serial OLED modules, thiab serial TFT modules, nrog rau ntau yam kev sib tshuam xws li SPI, I2C, UART, USB, RS232, thiab RS485.
