LMG7524RPFC KOE 4.7"320×240 FSTN-LCD LCM 320×240
LMG7524RPFC is mature KOE 4.7-inch QVGA monochrome FSTN industrial graphic LCD module, mass pre-installed on small automation equipment operation panels and desktop portable test instruments.100 cd/m² moderate brightness meets indoor workshop, office and laboratory lighting environments. Negative black-on-white high contrast display delivers clear multi-line equipment parameter tables, real-time waveform curves and fault alarm text, suitable for long-time static data monitoring.
12Pin 4-bit parallel MCU signal features stable anti-electromagnetic interference performance, normal image output in light dust workshop environments, fully compatible with mainstream industrial single-chip microcomputer, ARM and PLC control mainboards. Single edge detachable CCFL lamp design allows users to replace aging lamp tubes alone instead of the whole LCD module, effectively reducing on-site maintenance costs. Compact thin aluminum frame saves internal space of small embedded control cabinets and portable field testers.
