General Description
* Description
LMS350GF21 is a TMR(Transmissive with Micro Reflective) type color active matrix
TFT (Thin Film Transistor) liquid crystal display (LCD) that uses amorphous silicon TFT
as a switching devices. This model is composed of a TFT-LCD module, a driver circuit
and a back-light unit and a touch screen panel(TSP).
The resolution of a 3.5" contains 320xRGBx240 dots and can display up to 16.7M
colors.
* Features
- Transmissive with Micro Reflective type and back-light with six LEDs are available.
- Using the Touch Screen Panel(Film-Glass type).
- TN(Twisted Nematic) mode.
- Line inversion mode with stripe type.
- 24bit RGB Interface + Serial Peripheral Interface(SPI)
- SYNC(Vsync, Hsync, Dotclk) mode,
SYNC with DE(Enable, Vsync, Hsync, Dotclk) mode
- Gate Driver IC embeded on Panel(Double ASG)

Note (1) Test Equipment Setup
After stabilizing and leaving the panel alone at a given temperature for 30 min ,
the measurement should be executed. Measurement should be executed in a
stable, windless, and dark room. 30 min after lighting the back-light. This should
be measured in the center of screen.

4-3. Integration Design Guide
- Give enough clearance(over 0.3mm) between the touch-panel and a display
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.

14. General Precautions
14.1 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. If you leave the droplets for a
long time, Staining and discoloration may occur.
(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,
Ethyl acid 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 Integrated Gate
Circuit.
(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
14.2 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.

14.3 Operation
(a)
Do not connect, disconnect the module in the "Power On" condition.
(b) Power supply should always be turned on/off by the "Power on/off sequence"
14.4 Others
(a) The Liquid crystal is deteriorated by ultraviolet, do not leave it in direct
sunlight and strong ultraviolet ray 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.
(f) Avoid shortness between LED soldering pad and TSP soldering pad.
