10 / 26 page Doc. No.: Issued Date : Aug.9.2006 Model No :G104V1-T01 Approval 10 / 26 Version 2.1 3.2 BACKLIGHT UNIT Ta = 25 ± 2 ºC Value Parameter Symbol Min. Typ. Max. Unit Note Lamp Input Voltage VL 440 490 540 VRMS (1), IL = (5.5) mA Lamp Current IL 2.0 5.5 6.0 mARMS (1) - - 770 (25 oC) VRMS (2) Lamp Turn On Voltage VS - - 960 (0 oC) VRMS (2) Operating Frequency FL 45 - 80 KHz (3) Lamp Life Time LBL 50,000 - - Hrs (5) Power Consumption PL - 5.39 - W (4), IL = 5.5 mA Note (1) IL means the lamp current of one lamp. Note (2) The voltage shown above should be applied to the lamp for more than 1 second after startup. Otherwise the lamp may not be turned on. Note (3) The lamp frequency may produce interference with horizontal synchronous frequency from the display, and this may cause line flow on the display. In order to avoid interference, the lamp frequency should be detached from the horizontal synchronous frequency and its harmonics as far as possible. Note (4) PL = IL ×VL ×2 Note (5) The lifetime of lamp can be defined as the time in which it continues to operate under the condition Ta = 25 ±2 oC and I L = ( 5.5 ) mArms until one of the following events occurs: (a) When the brightness becomes or lower than 50% of its original value. (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. 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.
