ACX704AKM 9.60cm (3.78 Type) QVGA Reflective Color LCD Module Description The ACX704AKM is a 9.60cm diagonal, QVGA formatted active matrix reflective color TFT-LCD with a high performance front light unit. This panel provides ultra-high reflectivity (30% typ.) with high contrast ratio (25:1 typ.). These characteristics are realized by a newly developed reflective electrode structure. In addition, this panel provides low power consumption (20mW typ.) which is realized by builtin 4-bit digital interface circuitry addressed by low temperature polycrystalline silicon transistors. Features * Number of dots: 320 x RGB x 240 * Dot size: 80m x 240m * High reflectivity: 30% (typ.) * High contrast ratio: 25:1 (typ.) * Number of colors: 4096 * Low power consumption: 20mW (typ.) * Built-in 4-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: 322 x 3 (H) x 242 (V) = 233,772 Number of active dots: 320 x 3 (H) x 240 (V) = 230,400 * Dimensions Module dimensions: 96.8 (W) x 73.0 (D) x 3.96 (H) (mm) Effective display dimensions: 76.800 (H) x 57.600 (V) (mm) Applications PDA, etc. Sony reserves the right to change products and specifications without prior notice.

TFT-LCD panels are easily damaged by static charges. a) Use non-chargeable gloves, or simply use bare hands. b) Use an earth-band when handling. c) Do not touch any electrodes of a panel. d) Wear non-chargeable clothes and conductive shoes. e) Install grounded conductive mats on the working floor and working table. f) Keep panels away from any charged materials. g) Use ionized air to discharge the panels. (2) Protection from dust and dirt a) Operate in a clean environment. b) Do not touch the front light surface. The surface is easily scratched. c) Use ionized air to blow dust off the panel. (3) Others a) Do not twist or bend the flexible PC board especially at the connecting region because the board is easily deformed. b) Do not drop the module. c) Do not twist or bend the module. d) Keep the module away from heat sources. e) Do not dampen the module with water or other solvents. f) Avoid storage or use the module at high temperatures or high humidity, as this may result in damage. - 31 - ACX704AKM Package Outline Unit: mm 73 (Outer Frame) (Metal Bezel Opening) 62.2 0.15 57.6 (Active Area) (39.6) 28.7 0.08 6.8 9.4 1.6 7 5.4 (6) 1.06 (FPC) 3.96 0.3 Electrode 45 (34.8) 3 5 (38.2) 9.46 5)Mass:56g 4)FPC-connector:FF02(JAE) 3)CCFL-connector:BHSR-02VS-1(JST) 2)The rotation angle of the active area relative to H and V is 1.
