The Sharp LM7M633 LCD Module is a 6.5″ CSTN-LCD designed primarily for legacy systems, embedded platforms, and retrofit applications requiring basic color display performance within a slim, energy-conscious design.
This module features a 640(RGB)×240 resolution (HVGA), yielding a pixel density of 105 PPI, suitable for simple graphical interfaces, status readouts, and control dashboards. The active display area measures 153.58 mm (W) × 57.58 mm (H), providing a wide, letterbox-style layout that’s ideal for horizontally oriented content.
Built with CSTN (Color Super Twisted Nematic) technology, the display operates in a normally black, transflective mode. This allows for partial visibility under ambient light even without backlighting, which contributes to power efficiency in portable or always-on systems.
While its brightness is limited to 40 cd/m² and its contrast ratio stands at 10:1 (typical for TM) and 8:1 (typical for RF), these levels are sufficient for non-critical viewing environments such as equipment diagnostics, legacy terminals, or control rooms. A 75Hz frame rate ensures smoother transitions in applications with basic animations or content refresh.
The display supports 8-bit parallel data input through a 20-pin connector, operates at a 3.3V power supply, and features a single CCFL backlight rated for 10,000 hours (note: backlight driver not included).
Designed for indoor use, the LM7M633 functions within an operating temperature range of 0°C to 40°C, making it a reliable and cost-effective display solution for applications that prioritize simplicity and durability over high-end visual fidelity.
