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 using the module at high temperature or high humidity, as this may result in damage. - 19 - Package Outline (75.5) 71.4 (Outer frame) 6.4 0.3 63.4 (Cover plate) 60 (Window) (2) (3.3) (59.4) 57.6 (Active area) (6.3) 38.1 (11.3) (1.7) (6.3) 2 (33.3) 8 7.12 5.42 +0.1 0 1 2 3 4 5 6 (1.6) 8.1 (2) Front sheild case Rear sheild case Flexible cable Driving board Label Cover plate 71.4 0.3 (Outer frame) Unit: mm (5.5) 59.6 +0.1 0 (Window) (7.5) 52.6 0 -0.1 ( Parts area) 1 (9) (10) ACX705AKM-01 2 27.52 6 40.8 +0.1 0 52 37 0.3 +0.1 0 (40.2) 0 52 0.3 44.2 (Cover plate) 38.4 (Active area) (Window) 35 -0.1 (Parts area) (Window) 4 Active area center (Outer frame) (24.48) - 20 - (6) (7) 6 7 8 ACX705AKM-7 T 4 (2) (4.08) (2.38) 5 (5.9) (5.93) (26.4) Note 1) Tolerance with no indicatin (0.1) 2) 0.3 (8.75) 0.5 3 5.5 (1.15) 30.5 11.5 : control dimension (minimum) ACX705AKM Sony Corporation |
