PIXEL FAULT
There are two pixel faults - bright fault and dark fault - that are respectively defined as follows.
(1) BRIGHT
FAULT
In this pixel fault, a c ell that should not light originally is lighting or flashing on and off.
For checking this pixel fault, input ALL BLACK SCREEN and find out the cell that is lighting or flashing on and off.
(2) DARK
FAULT
In this pixel fault, a cell that s hould light originally is not lighting or not flashing on and off or lighting with the brightness twice as brighter as
originally lighting.
For checking this pixel fault, input 100% of each RGB color and find out the c ell that is not lighting or not flas hing on and off or lighting with
the brightness as brighter as originally lighting.
