Sony ACX709AKN Datasheet
7.60cm Reflective Color LCD Module
Description
The ACX709AKN is a 7.60cm diagonal, 320 × 320
dots (102,400 effective pixels) active matrix reflective
color TFT-LCD module with a high performance front
light unit with touch panel. This panel provides ultrahigh reflection ratio with high contrast ratio. These
characteristics are realized by a newly developed
reflective electrode structure.
Features
• Number of effective dots: 320 × 320
• Pixel pitch: 168µm × 168µm
• High reflection ratio
• High contrast ratio
• Number of colors: 262,144
• Compact size
• Thin and bright front light unit with touch panel
