[Note 1] Backlight driving conditions (operating frequency fL especially) may interfere with horizontal frequency fH, causing the beat or flicker on the display. Therefore the operating frequency fL shall be adjusted in relation to horizontal frequency fH to avoid interference. [Note 2] The inverter open voltage should be large than start up voltage, otherwise backlight may blinking for a moment after turns on or not be turned on. And this voltage should be applied to lamp for more than 1 second to start up, otherwise backlight may not be turned on. [Note 3] If driving current waveform is asymmetrical, mercury deviation inside of CFL will incline to one side and consequently abnormal lighting may occur. To prevent such unfavorable lighting, driving current waveform is asked to have unbalance rate of less than 10% and wave-height rate of less than 2 +/- 10%. And this driving waveform shall be confirmed in your system.
Unbalance rate = | Ip - I-p | / IL x 100 (%) Ip Wave-height rate = Ip (or I-p) / IL Ip I-p IL Current waveform : High peak value : Effective value
I-p : Low peak value
[Note 4] The inverter of ground reference type should be used. The inverter of ground floating type should not be used.

PARAMETER P-P of jitter / 100 cycles Jitter rate SYMBOL tcj1 tcj2 MIN TYP MAX 300 20 UNIT ps ps/cycle NOTE Note 1
[Note 1] Please confirm tcj2 (Jitter rate), only if tcj1 (P-P of jitter/100cycles) exceeds 300ps. [Additional explanation] Right diagram shows the example of CYCLE JITTER of LVDS CLOCK. According to this diagram, tCLK MIN. is 15.0ns and tCLK MAX. is 15.42ns between 0nc and 100nc. The tcj1 (P-P of jitter / 100 cycles) in this sphere is tcj1=15.42-15.0=0.42 ns and out of specification (300ps MAX.). So, it is neccesary to measure tcj2 (jitter rate) and to judge whether it conform to above specification. According to the diagram, the sharpest fluctuation of tCLK is 0.4ns per 5nc. So that, the tcj2 in this sphere is
15.6 15.5 Period t CLK (ns) 15.4 15.3 15.2 15.1 15.0 14.9 0 50 100 Cycle 150 200 250

When the power is off, LVDS input must be kept at either low level or high impedance.
Power sequence for CFL (backlight) is not specified especially, however it is recommended to consider some timing difference between LVDS input as shown above. If backlight lights on before LCD starts function, or if backlight is kept on after LCD stopped function, screen may look white for a moment or abnormal image may be displayed. This is caused by variation in output signal from timing generator at LVDS input on or off. It does not cause damage to liquid crystal molecule and driving circuit.

PRECAUTIONS (INSTRUCTIONS FOR SAFE AND PROPER USE) 1. Instructions for safety
(1) Please do not disassemble or modify LCD module to avoid the possibility of electric shock, damage of electronic components, scratch at display surface and invasion of foreign particles. In addition, such activity may result in fire accident due to burning of electronic component. LCD module disassembled or modified by customer is out of warranty. Please be careful in handling of LCD module with broken glass. When the display glass breaks, please pay attention not to injure your fingers. The display surface has the plastic film attached, which prevents dispersion of glass pieces, however touching broken edge will injure your fingers. Also CFL (Cold Cathode Fluorescent Lamp) is made of glass, therefore please pay attention in the same way. Please do not touch the fluid flown out of broken display glass. If the fluid should stick to hand or clothes, wipe off with soap or alcohol immediately and then wash it with water. If the fluid should get in eyes, wash eyes immediately with washing lotion for more than 15 minutes and then consult the doctor. Please make secure connection of CFL connector. Please make sure that CFL connector from LCD module is connected with output connector on inverter circuit securely. Poor connection may cause smoke or fire accident due to high voltage in circuit. If connection may not be secure, please switch off the power supply for LCD module and CFL and then make secure connection. Please do not make connection with another connector than recommended mating connector. CFL contains mercury inside. Please follow regulations or rules established by local autonomy at its disposal. Please be careful to electric shock. Before handling LCD module, please switch off the power supply. Since high voltage is applied to CFL terminal, cable, connector and inverter circuit in operation mode, touching them will cause electric shock.

2. Instructions for designing
(1) Mounting of LCD Please fix LCD module at all mounting flanges shown in this specification for installation onto system. The used screws should have proper dimensions. Furthermore, designing of mounting parts should be adequate so that LCD module is not putted stresses (ex. warped, twisted and pressed stress), to achieve good display quality. The stresses may cause non-uniformity even if there is no nonuniformity statically. Polarity of power supply for CFL Please give careful consideration in designing so that each polar of cable should be connected correctly at assembling (i.e. high voltage side is connected to high voltage side and low voltage side is connected to low voltage side). Since longer CFL cable may cause insatiable start-up of CFL and reduction of brightness, please make cable short as much as possible.

Ver.2 Page 12/16
(3)
Designing of power supply circuit for CFL Please design the circuit so that high voltage output can be kept for more than 1 second. The shorter time may not start up CFL. The driving inverter circuit is recommended to be the type which CFL current can be controlled. The type which voltage is controlled is not recommended, because it may cause big current under high temperature and insatiable start-up of CFL under low temperature. Heat radiation CFL generates heat at lighting and causes temperature rise inside system. Therefore, designing to radiate heat like radiation slits at cabinet is recommended to meet the specified operating temperature range for LCD module. Noise on power line Spike noise contained in power line causes abnormal operation of driving circuit and abnormal display. To avoid it, spike noise should be suppressed below VDD +/- 200mVp-p. (In any case, absolute maximum rating should be kept.) Power sequence Before LCD module is switched on, please make sure that power supply and input signals of system, testing equipment, etc. meet the recommended power sequence. Absolute maximum rating Absolute maximum rating specified in this specification has to be kept in any case. It shows the maximum that cannot be exceeded. Exceeding it may cause burning or non-recoverable break of electronic components in circuit. Please make system design so that absolute maximum rating is not exceeded even if ambient temperature, input signal and components are varied. Protection for power supply Please study to adapt protection for power supply against trouble of LCD module, depending on usage condition of system. Fuse installed on LCD module should be never modified. Any modification to make the function of fuse ineffective may cause burning or break of printed wiring board or other components at circuit trouble. Protection against electric shock High voltage is applied to CFL connector, inverter circuit and CFL at lighting. Please make design not to expose or be accessible to such high voltage parts to avoid electric shock.

(10) Protection cover and cut-off filter for ultraviolet rays When LCD module is used under severe condition like outdoor, it is recommended to use transparent protection cover over display surface to avoid scratches and invasion of dust and water. In addition, when LCD module is exposed to direct sun light for long time, use of cut-off filter for ultraviolet rays is also recommended. Please be careful not to get condensation.
3. Instructions for use and handling
(1) Protection against Static electricity C-MOS LSI and semiconductors are easily damaged by static discharge. LCD module should be handled on conductive mat by person grounded with wrist strap etc. to avoid getting static electricity. Please be careful not to generate static electricity during operation.
Tottori SANYO Electric Co., Ltd.
TM141XG-02L05
Ver.2 Page 13/16
(2)
Protection against dust and stain LCD module should be handled in circumstance as clean as possible. It is recommended to wear fingerstalls or ductless and soft gloves before handling to avoid getting dust or stain on display surface. Protection film for display surface It is recommended to remove protection film at nearly final process of assembling to avoid getting scratch or dust. To remove film, please pick up its edge with dullhead tweezers or cellophane tape at first and then remove film gradually taking more than 3 seconds. If film is removed quickly, static electricity may be generated and may damage semiconductors or electronic components. Contamination of display surface When display surface of LCD module is contaminated, please wipe the surface softly with cotton swab or clean cloth. If it is not enough, please take it away with cellophane tape or wipe the surface with cotton swab or clean cloth containing benzine. In this case, please be careful so that benzine does not get in inside of LCD module, because it may be damaged. Water drop on LCD surface Please do not leave LCD module with water drop. When the display surface gets water drop, please wipe it off with cotton swab or soft cloth immediately, otherwise display surface will be deteriorated. If water gets in inside of LCD module, circuit may be damaged. Please make sure that LCD module is not warped or twisted at installation into system. Even temporary warp or twist may be the cause for failure. Mechanical stress Please be careful not to apply strong mechanical stress like drop or shock to LCD module. Such stress may cause break of display glass and CFL or may be the cause for failure. Pressure to display surface Please be careful not to apply strong pressure to display surface. Such pressure may cause scratches at surface or may be the cause of failure. Protection against scratch Please be careful not to hit, press or rub the display surface with hard material like tools. In addition, please do not put heavy or hard material on display surface, and do not stack LCD modules. Polarizer at front surface can be easily scratched.

(10) Plugging in of connector Please be careful not to apply strong stress to connector part of LCD module at plugging in or out, because strong stress may damage the inside connection. At plugging in connector, place LCD module on the flat surface and hold the backside of connector on LCD module. Please make sure that connector is plugged in correctly. Insecure connection may be the cause for failure during operation. In addition, please be careful not to put the connecting cable between cabinet of system and LCD module at installing LCD module into system. (11) Handling of CFL cable and FPC (Flexible Printed Circuit) Please be careful not to pull or scratch CFL cable, because CFL or soldered part of cable may be damaged consequently. Also FPC should not be pulled or scratched. (12) Switching off before plugging in connector Please make sure that power is switched off before plugging in connector. If power is on at plugging in or out, circuit of LCD module may be damaged. When LCD is switched on for test or inspection, please make sure that power supply and input signals of driving system meet the specified power sequence.

(13) Temperature dependence of LCD display Response speed (optical response) of LCD display is dependent on temperature. Under low temperature, response speed is slower. Also brightness and chromaticity change slightly depending on temperature. (14) Slow light-up and life time of CFL under low temperature Under low temperature, start-up of CFL gets difficult. (The time from switch-on to stable lighting becomes longer.) As characteristic of CFL, operation under low temperature makes the life time shorter. To avoid this, it is recommended to operate under normal temperature. (15) Condensation LCD module may get condensation on its display surface and inside in the circumstance where temperature changes much in short time. Condensation can cause deterioration or failure. Therefore, please be careful not to get condensation. (16) Remaining of image Displaying the same pattern for long time may cause remaining of image even after changing the pattern. This is not failure but will disappear with time.
4. Instructions for storage and transportation
(1) Storage Please store LCD module in the dark place of room temperature and low humidity in original packing condition, to avoid condensation that may cause failure. Since sudden temperature change may cause condensation, please store in circumstance of stable temperature. Stacking number Since excessive weight causes deformation and damage of carton box, please stack only up to the number stated on carton box for storage and transportation. Handling Since LCD module consists of glass and precise electronic components, it will be damaged by excessive shock and drop. Therefore, please handle the carton box carefully to minimize shock at loading, reloading and transportation.
