Notes: 1. The specified current and power consumption are under the Vcc = 5.0V , 25◈, fv = 60Hz condition
whereas full black pattern is displayed and fv is the frame frequency.
2. This impedance value is needed to proper display and measured form TMDS Tx to the mating
connector.
3. The duration of rush current
is about 1ms
.
4. The variance of the voltage is ±10%.
5. The transformer output voltage in the inverter must be high, considering loss of the ballast
capacitor in the inverter.
6. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
T
s
is the time required for the brightness of the center of the lamp to be not less than 95%.
7. The lamp power consumption shown above does not include loss of external inverter.
8. The life time is determined as the time at which brightness of lamp is 50% compared to that of initial
value at the typical lamp current on condition of continuous operating at 25 ±2◈.
◈ 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.

Interface Connections
This LCM has three interface connections, a 20 pin connector is used for the module electronics and, two four pin
connectors are used for the integral back light system.
The interface pin configuration for the connector is shown in the table below.
LCD Connector : DF19KR-20P-1H(Hirose) or GT100-20P-LS-SMT-R(LG Cable)
Mating Connector : DF19G-20S-1C(Hirose cable type) or DF19G-20S-1F(Hirose FPC type)
