12. Supply Voltage Sequence Condition
DO NOT apply DC voltage to the LCD panel. DC voltage induce irreversible electrochemical
reactions and reduce LCD life. Always follow the power supply ON/OFF sequence of VDD first,
input signal second, VCONT third and finally DISP. This will prevent DC driving of the LCD or
CMOS LSI latch up as shown below.

* The above sequence should be designed as to keep each normal figure on condition that liquid

* Control the input signal and VCONT to the above ON - OFF timing when you switch ON/OFF the
display during VDD and DISP are on.
And design the circuit as VCONT's OFF level become GND level at the some time.

14.Design Guidance for Analog Touch-Panel(T/P)
14-1. Electrical
In customer's design, please remember the following considerations.
1.
2.
3.
4.
Do not use the current regulated circuit.
Keep the current limit with top and bottom layer.(See Sec, 4-1)
Analog T/P can not sense two point touching separately.
A contact resistance is appeared at the touch point between top and bottom layer.
After this resistance has stable read the T/P position data.
5. Analog T/P is also a "Capacitor" in an equivalent circuit.
Design your sensing circuit and low-pass filter with considering this "Capacitor" value.
6. Because noise of inverter or peripheral circuits may interfere signal of touch panel itself
it is necessary to design carefully in advance to avoid these noise problem.
14-2. Software
1. Do the "User Calibration".
2. "User Caribration" may be needed with long term using.
Include "User Caribration" menu in your software.
3. When drawing a line with a stylus, there may be a slight discontinuity when the stylus passes
over a spacer-dot. If necessary, please provide a compensation feature within your software.
14-3. Mechanical Design
14-3-1.Each "Area"
Please confirm the following information before starting your design.
(a) Key Area
"Key Area" is an area where T/P specifications(Linearity,Durability,Actuation force, etc.) are
guaranteed.
1) Do a touch data sensing and calibration inside this area.
2) In normal cases it is a same size as your flat display's "active area".
3) The ITO layer durability near the edge of Key area is less stronger than the center.
(b) Transparent Insulation-paste Area.
Insulation-paste is printed with 1.0mm distance outer from "Key Area".
1) The purpose is to avoid potential shorting problem from the bezel housing edge from or
housing "stick" when molding.
2) Consider your housing edge position to keep 1.0mm distance from this paste line.
(See.Fig.1)
3) The cross section of this edge is taper shape. So if it is over the display's active area,
it will be shining as a prism.
(c) Prohibition Area
Input by pen and finger is prohibited in this area.
Because of the thickness around T/P, the ITO layer on the PET film will be expanded and as a
conclusion it will be cracked if pressed.(See.Fig.2)
1)
2)
3)
4)
We strongly recommend that the bezel should protect this area.
An exposure of this area and stylus contact should be avoided.
When assembling at the customer, do not press this area with tools.
Consider your design to avoid the pressure by the housing bezel.

14-3-2. 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.1)
3) Insertion a cushion material is recommended.
4) The cushion material should be limited just on the busbar insulation past area.
If it is over the transparent insulation paste area a "short" may be occurred.
5) If there is a probability of the touch panel surface being exposed to water, steam or other
liquids, then please take measures to ensure that the bezel / touch panel gap and housing
are "water tight".
6) There is a vent channel to equalize air pressure between the inner space of the touch panel
and the atmosphere. Please make sure it is not blocked by your housing and mounting method.
There is also the possibility that moisture could percolate into the touch panel if
moisture is allowed to accumulate around the air vent channel. Furthermore, avoid high air
pressures inside your housing which could cause the touch panel outer surface to swell out
from inflation.
14-3-3. Mounting on display and housing bezel
1) In all cases, the T/P should be supported form the backside of the glass.
2) Do not use an adhesive 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) If a dew will be on the heat-sealed area or exposed traces at the end of a flexible tail,
the migration of silver can occur.
This will cause sometimes a short circuit.
If your final product will used in a humid circumstance or will be moved from humid, warm
environments to cold ones, a dew condensation can occur.
Consider a water seal with your housing bezel.

16.Warranty
16-1. Incoming inspection
Please inspect the LCD within one month after your receipt.
16-2. Production Warranty
Kyocera warrants its LCDs for a period of 12 months after receipt by the purchaser, and within
the limits specified. Kyocera shall, by mutual agreement, replace or rework defective LCDs
that are shown to be Kyocera's responsibility.
- 21 -
17.Precautions for use
17-1. Installation of the LCD
1. Please ground either of the mounting (screw) holes located at each corner of an LCD module,
in order to stabilize brightness and display quality.
2. A transparent protection plate shall be added to protect the LCD and its polarizers.
3. The LCD shall be installed so that there is no pressure on the LSI chips.
4. The LCD shall be installed flat, without twisting or bending.
5. The display window size should be the same as the effective viewing area.
6. In case you use outside frame of effective viewing area as outward appearance of your product,
unevenness of its outward appearance is out of guarantee.
7. Do not pull the CFL lead wires and do not bend the root of the wires.
Housing should be designed to protect CFL lead wires from external stress.
8. We do not warranty optical performance outside of the active viewing area. Please ensure
that the bezel / housing minimizes area outside of "active viewing area" viewed by the end
user."
17-2. Static Electricity
1. Since CMOS ICs are mounted directly onto the LCD glass, protection from static electricity is
required. Operation should wear ground straps.
17-3. LCD Operation
1. The LCD shall be operated within the limits specified. Operation at values outside of these
limits may shorten life, and/or harm display images.
2. Vop must be adjusted to optimize viewing angle and contrast.
3. Operation of the LCD at temperature below the limit specified may cause image degradation
and/or bubbles.
It may also change the characteristics of the liquid crystal.
This phenomenon may not recover. The LCD shall be operated within the temperature limits
specified.
17-4. Storage
1. The LCD shall be stored within the temperature and humidity limits specified.
Store in a dark area, and protected the LCD from direct sunlight or fluorescent light.
2. The LCD should be packaged to prevent damage.
17-5. Screen Surface
1. DO NOT store in a high humidity environment for extended periods.
Image degradation, bubbles, and/or peeling off of polarizer may result.
2. The front polarizer is easily scratched or damaged.
Prevent touching it with any hard material, and from being pushed or rubbed.
3. The LCD screen may be cleaned with a soft cloth or cotton pad.
Methanol, or Isopropyl Alcohol may be used, but insure that all solvent residue is removed.
4. Water may cause damage or discoloration of the polarizer.
Clean any condensation or moisture from any source immediately.
5. Always keep the LCD free from condensation during testing.
Condensation may permanently spot or stain the polarizers.

* Each test item uses a test LCD only once. The tested LCD is not used in any other tests.
* The LCD is tested in circumstances in which there is no condensation.
* The tested LCD is inspected after 24 hours of storage at room temperature and room humidity
after each test is finished.
* The reliability test is not an out-going inspection.
* The results of the reliability test are for your reference purpose only.
The reliability test is conducted only to examine the LCD's capability.
