The Sharp LQ084V1DG21 is an 8.4-inch a-Si TFT-LCD display module engineered for industrial and embedded applications. This VGA-resolution panel delivers 640×480 pixels at 94 PPI with 262,144 colors and 300 cd/m² brightness. An antiglare hard-coated surface (3H) with antireflection properties minimizes glare across variable lighting environments. The transmissive, normally-white TN display offers a 250:1 contrast ratio and 20/40 ms response time. LED backlight technology provides ≥50,000 hours operational life, supporting energy-constrained designs.
