The Sharp/AVC Group LQ121S1DG11 is a 12.1-inch amorphous silicon TFT-LCD module engineered for industrial and commercial display systems. This SVGA panel delivers 800 × 600 pixel resolution with 262,144 colors (6-bit per color) and typical brightness of 250 cd/m². The mature TFT-LCD architecture provides consistent panel-to-panel performance and long-term stability—critical attributes for systems requiring industrial or medical certification without re-qualification cycles.
