Standby (No H/V sync) < 1W Orange
Power off < 1W No display
5.7 VGA Cable Detect Test
If VGA cable of LCD monitor isn’t connected to video pattern generator or PC, “NO SIGNAL” should be shown
on screen.
5.8 Hi-Pot test
Test condition:
a. high voltage 2.3KV(DC)
b. leakage current 10mA
c. rising time 1 sec.
d. test time 3 sec.
5.9 Grounding Test
Test condition:
a. test current 30A / 2 sec
b. impedance < 0.1Ω
5.10 Bumping Test
5.10.1 Test mode: 1280x1024 @ 60 Hz;
5.10.2 Test pattern: pattern #1 of crosshatch (GENERAL-1)
5.10.3 To shock LCD monitor lightly at the center of rear cover and edges with 1~2kg/cm2 force for three
times, no abnormal phenomenon is found on panel screen.
6. DISPLAY CHECK
6.1 Panel Flicker Check
Connect LCD monitor to PC, set LCD monitor to be timing of 1280x1024@60 Hz, adjust brightness to be
default value (brightness at maximum), execute “Auto” function, and then check picture of shut down under
windows operating system, or flicker-pattern of pixel on-off. It should be that no flicker be found on panel
screen.
6.2 Panel Defect Inspection
6.2.1 Test mode: 1280 x 1024@60Hz
6.2.2 Test pattern: Crosshatch/Full white/Red/Green/Blue/Black/16 color bar/64 gray bars
6.2.3 Display quality must be (according to DIN 13406-2 pixel fault class II)
