1. General points
1.1 During the test and measuring, supply a distortion free AC
mains voltage to the apparatus via an isolated transformer
with low internal resistance.
1.2 All measurements mentioned hereafter are carried out at a
normal mains voltage (90 - 132 VAC for USA version,
195 -264 VAC for EUROPEAN version,or 90 - 264 VAC for
the model with full range power supply, unless otherwise
stated.)
1.3 All voltages are to be measured or applied with respect to
ground, unless otherwise stated.
Note: don' t use heat-sink as ground.
1.4 The test has to be done on a complete set including LCD
panel in a room with temperature of 25 +/- 5 degree C.
1.5 All values mentioned in these test instruction are only
applicable of a well aligned apparatus, with correct signal.
1.6 The letters symbols (B) and (S) placed behind the test
instruction denotes
(B): carried out 100% inspection at assembly line
(S): carried out test by sampling
1.7 The white balance (color temperature), has to be tested in
subdued lighted room.
1.8 Repetitive power on/ off cycle are allowed. The image can
be displayed after 8 sec.
1.9 All optical characteristics (including WHITE-D, Brightness,
and so on) are determined according to panel specification
after warming up approximate 30 minutes that brightness
stability is optimal, and follow strictly after panel specification.
