Note (2) Test Equipment Setup
After stabilizing and leaving the panel alone at a given temperature for 30min, the
measurement should be executed. Measurement should be executed in a stable,
windless, and dark room. 30min after lighting light source. This should be measured in
the center of screen.

4.3 Design Guide
- Give enough clearance (over 0.3mm) between the touch panel and a display device to
protect a display.
- Avoid the design that Front-case overlap and press on the active area of the touch panel.
- Give enough gap (over 0.5mm at compressed) between the front case and touch panel to
protect wrong operating.
- Use a buffer material (Gasket) between the touch panel and Front-case to protect damage
and wrong operating.
- Avoid the design that buffer material overlap and press on the inside of touch panel
viewing area.

General Precautions
11.1 Handling
(a) When the module is assembled, it should be attached to the system firmly.
Be careful not to twist and bend the module.
(b) Refrain from strong mechanical shock and / or any force to the module. In addition to
damage, this may cause improper operation or damage to the module and back-light unit.
(c) Note that polarizers are very fragile and could be easily damaged. Do not press or
scratch the surface harder than a HB pencil lead.
(d) Wipe off water droplets or oil immediately.
Staining and discoloration may occur.
If you leave the droplets for a long time,
(e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth.
(f) The desirable cleaners are water, IPA(Isopropyl Alcohol) or Hexane. Do not use Ketone
type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethylacid or Methyl chloride.
It might permanent damage to the polarizer due to chemical reaction.
(g) If the liquid crystal material leaks from the panel, it should be kept away from
the
eyes or mouth. In case of contact with hands, legs or clothes, it must be washed away
thoroughly with soap.
(h) Protect the module from static, it may cause damage to the CMOS Gate Array IC.
(i) Use finger-stalls with soft gloves in order to keep display clean during the incoming
inspection and assembly process.
(j) Do not disassemble the module.
(k) Protection film for polarizer on the module shall be slowly peeled off just before use so
that the electrostatic charge can be minimized.
(l) Pins of I/F connector shall not be touched directly with bare hands.

11.2 Storage
(a) Do not leave the panel in high temperature, and high humidity for a long time.
It is highly recommended to store the module with temperature from 0 to 35°C
and relative humidity of less than 70%.
(b) Do not store the TFT-LCD module in direct sunlight.
(c) The module shall be stored in a dark place. It is prohibited to apply sunlight
or fluorescent light during the store.
11.3 Operation
(a) Do not connect, disconnect the module in the "Power On" condition.
(b) Power supply should always be turned on/off
by the item 7.3 "Power on/off sequence"
11.4 Others
(a) The liquid-crystal is deteriorated by ultraviolet rays. Do not leave it in direct sunlight
and strong ultraviolet rays for many hours.
(b) Avoid condensation of water. It may result in improper operation or disconnection of
electrode.
(c) Do not exceed the absolute maximum rating value. ( the supply voltage variation, input
voltage variation, variation in part contents and environmental temperature, and so on)
Otherwise the panel may be damaged.
(d) If the panel displays the same pattern continuously for a long period of time,
it can be the situation when the image "Sticks" to the screen.
(e) This panel has its circuitry FPC on the bottom side and should be handled carefully in
order not to be stressed.
