ACX705AKM

6.92cm Diagonal Reflective Color LCD Module

Description

The ACX705AKM is a 6.92cm diagonal active
matrix reflective color TFT-LCD module with a front
light unit and a driving board. This module provides
low power consumption which is realized by built-in
3-bit digital interface circuitry.

Features

• Number of dots: 240 × RGB × 160

• Dot size: 80µm × 240µm

• High reflectivity: (25% typ.)

• High contrast ratio: (13:1 typ. at the condition of turning off the front light)

• Number of colors: 512

• Low power consumption (47mW typ.) with a driving board composed of a LCD controller IC,

a reference driver IC and a DC-DC convertor

• Built-in 3-bit digital interface circuitry

• Compact size

• Thin and bright front light unit

Element Structure

• Active matrix TFT-LCD panel with built-in peripheral driving circuitry using low temperature polycrystalline

silicon transistors

• Number of dots

Total number of dots: 242 × 3 (H) × 162 (V) = 117,612
Number of active dots: 240 × 3 (H) × 160 (V) = 115,200

• Dimensions

Module dimensions: 71.4mm × 52.0mm × 4.8mm (t) (parts area 6.5mm (t) max.)
Effective display dimensions: 57.6mm (H) × 38.4mm (V)

Applications

PDA, etc.
