page 4 handling precautions 1) since front polarizer is easily damaged, be extremely careful when handling panel. 2) be sure to turn off power supply wh en inserting or disconnecting from input connectors. 3) wipe off water immediately. long contact with water may cause discoloration or spots. 4) when the panel surface is soiled, wipe it with absorbent cotton or other soft cloth. 5) since the panel is made of glass, it may break or crack if dropped or bumped on a hard surface. 6) since cmos lsi is used in this module, be careful of st atic electricity by grounding those handling the display. 7) do not open nor modify the module assembly. 8) do not press or touch the panel surface with hands or tools. 9) do not press or move the reflector sheet at the back of the modul e in any direction. 10) in case the module has to be put back into the packing container slot from where it was taken, do not press the center of t he ccfl reflector edge. instead, press at the far ends of the ccfl reflector edge softly. otherwise the tft module may be damaged. 11) **at the insertion or removal of the signal interface connector, be sure not to rotate nor tilt the interface conne ctor of the tft module. 12) after installation of the tft module into an enclosure (desktop monitor bezel, for example), do not twist nor bend the tft module even momentarily. design the enclosure so that no bending/twisting forces are applied to the tft module. otherwise the tft module may be damaged. www.datasheet.co.kr datasheet pdf - http://www..net/

(b) when the effective ignition length become s 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 specif ications for the modularized lamp. the performance of the backlight, such as lifet ime 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 ca used by the mismatch of the backlight and the inverter (miss-lighting, flicker, et c.) never occurs. if the above situation is confirmed, the module should be operated in the same manners when it is installed in your instrument. www.datasheet.co.kr datasheet pdf - http://www..net/
page 11 the output of the inverter must have sy mmetrical (negative and positive) voltage waveform and symmetrical current wavefo rm.(unsymmetrical ratio is less than 10%) please do not use the inverter which ha s unsymmetrical voltage and unsymmetrical current and spike wave. lamp frequency ma y 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 fr om the horizontal sync hronous 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 mo re reliable lamp. it shall help increase the lamp lifetime and reduce its leakage current. a. the asymmetry rate of the inve rter waveform should be 10% below; b. the distortion rate of t he waveform should be within 2 10%; c. the ideal sine wave form shall be symme tric in positive and negative polarities. * asymmetry rate: |i p ? i ?p | / i rms * 100% * distortion rate i p (or i ?p ) / i rms www.datasheet.co.kr datasheet pdf - http://www..net/

page 17 power on/off sequence to prevent a latch-up or dc operation of lcd module, the power on/off sequence should follow the conditions shown in the following diagram. note. (1) the supply voltage of the external system for the module input should be the same as the definition of vcc. (2) please apply the lamp voltage within the lcd operation range. when the backlight turns on before the lcd operation of the lcd turns off, the display may, instantly, function abnormally. (3) in case of vcc = off level, please keep the level of input signals on the low or keep a high impedance.
