The Sharp LM64P89L is a 9.4-inch monochrome Super Twisted Nematic (STN) LCD module tailored for industrial, professional, and embedded control systems where long-term reliability and basic graphical performance are critical. With a VGA resolution of 640×480 pixels and a pixel density of 76 PPI, it provides crisp, clear data visualization suitable for diagnostics, monitoring, and legacy system interfacing.
This panel features a transmissive STN architecture with a typical contrast ratio of 18:1 (TM), ensuring readability in standard indoor conditions. While the contrast is modest compared to TFT technologies, it’s well-suited for text-heavy, non-graphically intensive interfaces.
Equipped with a single CCFL backlight system (driver not included), the module supports stable operation for long periods, ideal for 24/7 systems. It lacks touchscreen functionality, aligning it with applications where tactile input is not required.
