5.1 inch 240x128 Graphic LCD Module is a 5.1 inch monochrome, 240×128 dot matrix, COB (chip on board) graphic LCD module. In FSTN positive display LCD mode wide temperature range (operating temperature: -20°C to 70°C, storage temperature: -30°C to 80°C), with white LED backlight, the overall display effect is white background gray character. It has a six o'clock viewing direction and a semi-transparent reverse polarizer, recommended for indoor and outdoor applications. This product has negative voltage and is assembled on board chip with 1/128 Duty and controller IC RA8803 or equivalent. The interface type is parallel. This is a ROHS compliant product manufactured in accordance with ISO standards and procedures.
Core feature analysis:
Display performance
Monochrome STN yellow-green display with semi-transparent anti-polarizer to achieve dual-mode viewing indoors and outdoors:
?? Relying on reflected light in strong light environment (no backlight required)
?? Enable yellow-green LED backlight in low illumination (typical current <30mA)
Contrast automatic optimization technology (V0~V6 voltage adjustable), adapting to extreme temperature difference of -20℃~70℃
Hardware architecture
RA8803 controller integrated functions:
?? Support automatic identification of 8080/6800 parallel interface
?? Built-in 128KB video memory (support 240x128 full frame cache)
?? Hardware drawing acceleration (linear/circular/bit block transfer)
COB packaging process, vibration resistance up to 5G@10-500Hz
Power management
Negative voltage generation circuit design (typical VEE=-12V±5%)
Low power mode:
?? Sleep current <50μA (maintain video memory data)
?? Dynamic backlight PWM dimming (256 levels of brightness)
Typical application scenarios:
Industrial HMI
Production line control panel (compliant with IEC61000-4-2 ESD 8kV standard)
In-vehicle equipment
Special vehicle instrument (ISO 16750-3 mechanical vibration certification)
Smart instrument
Electricity meter/water meter outdoor display unit (MTBF>100,000 hours)
