6 / 28 page Product Specification 6 / 28 LM170E01 Liquid Crystal Display Ver 1.0 Mar. 28, 2005 3. Electrical specifications 3-1. Electrical characteristics The LM170E01-TLA1 requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and liquid crystal. Another which powers the CCFL, is typically generated by an inverter. The inverter is an external unit to the LCD. Table 2. Electrical Characteristics Note. The design of the inverter must have specifications for the lamp in LCD Assembly. The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from high-voltage output of the inverter. When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of the lamp and the inverter(no lighting,flicker,etc) never occurs.When you confirm it,the LCD Assembly should be operated in the same condition as installed in your instrument. Note. Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to conducting tape, TFT-LCD Module have a low luminance and the inverter has abnormal action because leakage current occurs between lamp wire and conducting tape. 1. The specified current and power consumption are under the VCC=5.0V, 25 C, fV(frame frequency) =60Hz condition. Mosaic(black & white) pattern shown in the [ Figure 3 ] is displayed. 2. The duration of rush current is about 5ms. And VCC rise time is 500us ± 20%. 3. Operating voltage is measured under 25 .The variance of the voltage is 10%. 4. The voltage above VBS should be applied to the lamps for more than 1 second for start-up. Otherwise,the lamps may not be turned on. Parameter Symbol Values Min. Typ. Max.
