※ Cautions when you turn on or off the power supply
① Turn on or off the power supply with simultaneously or the following sequence.
Turn on … VSHD→VSHA → VEE → VDD
Turn off … VDD → VEE → VSHA→ VSHD
② The input signal of “MOD” Terminals(Pin No.3 and No.4) must be low voltage when turning on
the power supply, and it is held until more than double vertical periods after VCC is turned on
completely. After then, it must be held high voltage until turning off the power supply.(Connect
Pin No.3 and No.4 terminals to the same signal.)
【Note 7-1】DCLK,SPL,SPR,LBR,LP,PS,REV,R0∼R5,G0∼G5 and B0∼B5 terminals are applied.
【Note 7-2】DCLK,SPL,SPR,LBR,LP,REV,R0∼R5,G0∼G5 and B0∼B5 terminals are applied.
【Note 7-3】PS terminal is applied.
【Note 7-4】MOD,CLS,SPS and U/L terminals are applied.
【Note 7-5】VCOMAC should be alternated on VCOMDC every 1 horizontal period and 1 vertical period.
VCOMDC bias is adjusted so as to minimize flicker or maximum contrast every each
module .

(11)Display quality
The display quality of the color TFT-LCD module shall be in compliance with
the Incoming Inspection Standards for TFT-LCD..
(12)Mechanical characteristics
12-1) External appearance
See Fig. 1
12-2) FPC (for LCD panel) characteristics
(1)Specific connector
FH12A-50S-0.5SH(HIROSE)
(2) Bending endurance of the bending slits portion
No line of the FPC is broken for the bending test (Bending radius=0.6mm and
angle=90°) in 30 cycles.
12-3) Design guidance for touchpanel(T/P)
12-3-1)Example of housing design
(1)If an consumer will put a palm on housing in normal usage, care should be taken as follows.
(2)Keep the gap, for example 0.3 to 0.7mm,between bezel edge and T/P surface.
The reason is to avoid the bezel edge from contacting T/P surface that may cause a “short”
with bottom layer(See Fig.2)
(3)Insertion a cushion material is recommended.
(4)The cushion material should be limited just on the busbar insulation paste area.
If it is over the transparent insulation paste area, a ”short” may be occurred.
(5)There is one where a resistance film is left in the T/P part of the end of the pole.
Design to keep insulation from the perimeter to prevent from mis-operation and so on.
sharp
LCY-02024−16
12-3-2)Mounting on display and housing bezel
(1)In all cases, the T/P should be supported from the backside of the glass.
(2)Do not to use an adhensive-tape to bond it on the front of T/P and hang it to the housing bezel.
(3)Never expand the T/P top layer(PET-film) like a balloon by internal air pressure.
The life of the T/P will be extremely short.
(4)Top layer, PET, dimension is changing with environmental temperature and humidity.
Avoid a stress from housing bezel to top layer, because it may cause “waving”.
(5)The input to the Touchpanel sometimes distorts touch panel itself.

(13)Handling Precautions
13-1) Insertion and taking out of FPCs
Be sure insert and take out of the FPC into the connector of the set after turning off the power
supply on the set side.
13-2) Handling of FPCs
The FPC for LCD panel shall be bent only slit portion. The bending slit shall be bent uniformly
on the whole slit portion with bending radius larger than 0.6mm ,and only inner side (back side
of the module). Don’t bend it outer side (display surface side).
Don’t give the FPCs too large force, for example, hanging the module with holding FPC.
12-3) Installation of the module
On mounting the module, be sure to fix the module on the same plane. Taking care not to warp or
twist the module.
13-4)Precaution when mounting
(1) If water droplets and oil attaches to it for a long time, discoloration and staining occurs. Wipe them off
immediately.
(2) Glass is used for the TFT-LCD panel. If it is dropped or bumped against a hard object, it may be broken.
Handle it with sufficient care.
(3)As the CMOS IC is used in this module, pay attention to static electricity when handling it. Take a
measure for grounding on the human body.
13-5)Others
(1) The liquid-crystal is deteriorated by ultraviolet rays. Do not leave it in direct sunlight and strong
ultraviolet rays for many hours.
(2) If it is kept at a temperature below the rated storage temperature, it becomes coagulated and the panel
may be broken. Also, if it is kept at a temperature above the rated storage temperature, it becomes
isotropic liquid and does not return to its original state. Therefore, it is desirable to keep it at room
temperature as much as possible.
(3) If the LCD breaks, don’t put internal liquid crystal into the mouth. When the liquid crystal sticks to the
hands, feet and clothes, wash it out immediately.
(4) Wipe off water drop or finger grease immediately. Long contact with water may cause discoloration or
spots.
(5) Observe general precautions for all electronic components.
(6) VCOM must be adjusted on condition of your final product. No adjustment causes the deterioration for
display quality.
(7) Static image should not be displayed more than 5 minutes in order to prevent from occurrence of
residual image.
