(3) life time (hr) of a lamp is defined as the time in which it continues to operate under the condition of ta = 252c and il = 7.0marms(max) for a lamp until the brightness becomes 50% or lower than it's original value. (4) if an inverter has shutdown function it should keep its output for more than 1 second even if the lamp connector open. otherwise the lamps may not to be turned on. www.datasheet.net/ datasheet pdf - http://www..co.kr/ 4. block diagram 4.1 tft lcd module preliminary doc . no LTA230W1-L02 rev. no. 0.0-041028 page /31 6 4 & |
