Caution
1. This general specification can be changed, just for your reference only. Kyocera will release specification later exclusive for you. Please refer to it as the formal document of specification. 2. This LCD is supposed to be for general electric appliances such as audio, office automation, industrial applications, home appliances and game machines. Do not use the LCD as a display for a medical instrument that is required extremely high reliability and its failure and malfunction may affect human lives. In the case you did, Kyocera will not take responsibility for it. 3. Kyocera may scrap the tooling or stop supplying the LCD, after 2 year time frame from your latest purchase of the LCD.

Supply Voltage Sequence Condition of LCD 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, V0-V5 third and finally DISP. This will prevent DC driving of the LCD or CMOS LSI latch up as shown below. 1s MIN. 1s MIN.

The Non-load output voltage (VS) of the inverter should be designed to have some margin, because VS may increase due to the leak current which may be caused by wiring of CFL cables. (Reference value: (936) Vrms MIN.) Do not apply more than (2.5)mA discharge tube current. Because CFL maybe broken due to over current. When the illuminance or quantity of light has decreased to 50 of the initial value. Average life time of CFL will be decreased when LCD is operating at lower and higher temperature

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. - 17 -
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.

Precautions for use 17-1. Installation of the LCD modules 1. The LCD module shall be installed so that there is no pressure on the LSI chips. 2. The LCD module shall be installed flat, without twisting or bending. 3. The display window size should be the same as the effective viewing area. 4. 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. 5. 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. 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. 2. Aluminum foil covering the terminal electrodes should remain in place until installed. 17-3. LCD module 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 module 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 module shall be stored within the temperature and humidity limits specified. Store in a dark area, and protected the LCD module from direct sunlight or fluorescent light. 2. The LCD module 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 may result. 2. The touch panel screen is easily scratched or damaged. Prevent touching it with any hard material, and from being pushed or rubbed. 3. Do not apply excessive force on the surface of touch panel, that is greater than the force specified by the spec. It may cause a color variation etc.on LCD display. 4. The touch panel 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. 5. Water may cause damage or discoloration of the touch panel screen. Clean any condensation or moisture from any source immediately. 6. Always keep the LCD module free from condensation during testing. Condensation may permanently spot or stain the touch panel screen.

b) Example of Randomizing Circuit Randomizing circuit is recommended in order to reduce "cross-talk" phenomenun of displayed images. (Tailing, vertical strips, etc ) Its detail is subject to change according to actual operating condition and application of the LCD . Should you have any question when installing an actual randomizing circuit , please ask Kyocera for details . b-1)
