Lamp life time
The back light system is an edge-lighting type with 2 CCFTs (Cold Cathode Fluorescent Tube).
The characteristics of the lamp are shown in the following table.
The value mentioned below is at the case of one CCFT.
CCFT Model Name : KTBE24MSTF-530.5KB270-Z-L (STANLEY ELECTRIC CO.,LTD)
Parameter
The kick-off voltage may rise up in the user set, please decide the open output voltage by checking not
to occur lighting failure under operating state.
The open output voltage should be applied to the lamp for more than 1 second to startup. Otherwise the
lamp may not be turned on.
Ambient temperature : 0∼50℃
may cause horizontal beat on the display. Therefore, adjust lamp frequency, and keep inverter as far as
from module or use electronic shielding between inverter and module to avoid interference.
The data don’t include loss at inverter.
Maximum rating for current is measured by high frequency current measurement equipment
connected to V
Lamp frequency : 40∼70kHz
(Note : To keep enough kick-off voltage and necessary steady voltage for CCFT.)
