Product Overview
The Sharp PN-LM431 is a 43-inch AQUOS BOARD interactive display with 4K UHD resolution, 20-point IR touch, and an Arm Cortex-A73/A53 octo-core processor for responsive whiteboard, annotation, and wireless collaboration in compact meeting spaces, huddle rooms, and training environments. The PN-LM series delivers 500 cd/m2 brightness and a 5-year warranty in a 43-inch form factor suited to small-room interactive display applications.
Product Description
The PN-LM431 uses a 42.5-inch TFT LCD with direct LED backlighting at 3840x2160 UHD and 0.2451mm pixel pitch, producing 104 ppi for sharp imagery at close viewing distances. Brightness reaches 500 cd/m2 maximum (450 cd/m2 typical) with a 4000:1 contrast ratio. The Arm A73+A53 octo-core SoC provides fast processing for interactive applications. Three HDMI inputs plus USB-C (DP Alt Mode), RS-232C and LAN control, 10W x 2 stereo speakers, and a 5-year limited warranty complete the specification.
