(b) when the effective ignition length becomes or lower than 80% of its original value. (effective ignition length is defined as an area that has less than 70% brightness compared to the brightness in the center point.) note (6) the waveform of the voltage output of inverter must be area-symmetric and the design of the inverter must have specifications for the modularized lamp. the performance of the backlight, such as lifetime or brightness, is greatly influenced by the characteristics of the dc-ac inverter for the lamp. all the parameters of an inverter should be carefully designed to avoid producing too much current leakage from high voltage output of the inverter. when designing or ordering the inverter please make sure that a poor lighting caused by the mismatch of the backlight and the inverter (miss-lighting, flicker, etc.) never occurs. if the above situation is confirmed, the module should be operated in the same manners when it is installed in your instrument. lcd module inverter 1 a hv (pink) 2 lv (white) current meter yokogawa 2016 a 1 a hv (blue) 2 lv (black)
dcc no.: 14029067 issued date: jan. 16th, 2002 model no.: m190e2 -l01 approval 10 / 28 version 2.0 the output of the inverter must have symmetrical (negative and positive) voltage waveform and symmetrical current waveform.(unsymmetrical ratio is less than 10%) please do not use the inverter which has unsymmetrical voltage and unsymmetrical current and spike wave. lamp frequency may produce interface with horizontal synchronous frequency and as a result this may cause beat on the display. therefore lamp frequency shall be as away possible from the horizontal synchronous frequency and from its harmonics in order to prevent interference. requirements for a system inverter design, which is intended to have a better display performance, a better power efficiency and a more reliable lamp. it shall help increase the lamp lifetime and reduce its leakage current. a. the asymmetry rate of the inverter waveform should be 10% below; b. the distortion rate of the waveform should be within 2 10%; c. the ideal sine wave form shall be symmetric in positive and negative polarities. i p i -p * asymmetry rate: | i p ? i ?p | / i rms * 100% * distortion rate i p (or i ?p ) / i rms

(1) the supply voltage of the external system for the module input should be the same as the definition of vcc. (2) apply the lamp voltage within the lcd operation range. when the backlight turns on before the lcd operation of the lcd turns off before the backlight turns off, the display may momentarily become abnormal screen. (3) in case of vcc = off level, please keep the level of input signals on the low or keep a high impedance. (4) t4 should be measured after the module has been fully discharged between power of and on period. (5) interface signal shall not be kept at high impedance when the power is on.

dcc no.: 14029067 issued date: jan. 16th, 2002 model no.: m190e2 -l01 approval 26 / 28 version 2.0 10. precautions 10.1 assembly and handling precautions (1) do not apply rough force such as bending or twisting to the module during assembly. (2) to assemble or install module into user?s system can be only in clean working areas. the dust and oil may cause electrical short or worsen the polarizer. (3) it?s not permitted to have pressure or impulse on the module because the lcd panel and backlight will be damaged. (4) always follow the correct power sequence when lcd module is connecting and operating. this can prevent damage to the cmos lsi chips during latch-up. (5) do not pull the i/f connector in or out while the module is operating. (6) do not disassemble the module. (7) use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft and easily scratched. (8) it is dangerous that moisture come into or contacted the lcd module, because moisture may damage lcd module when it is operating. (9) high temperature or humidity may reduce the performance of module. please store lcd module within the specified storage conditions. (10) when ambient temperature is lower than 10oc may reduce the display quality. for example, the response time will become slowly, and the starting voltage of ccfl will be higher than room temperature. 10.2 safety precautions (1) the startup voltage of backlight is approximately 1000 volts. it may cause electrical shock while assembling with inverter. do not disassemble the module or insert anything into the backlight unit. (2) 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, skin or clothes, it has to be washed away thoroughly with soap. (3) after the module?s end of life, it is not harmful in case of normal operation and storage.

risk of electric shock. disconnect the electric caution high voltage power before servicing. cold cathode fluorescent lamp in lcd panel contains a small amount of mercury please follow local ordinances or regulations for disposal.
