Normal mask indication
Dislocation of mask indication
Note:
The mask indication pattern indicated above is not a real pattern.
With the application-specific integrated circuit (ASIC) designed for the FHD panel, the mask indication may be dislocated.
When the unit is turned on with the panel mask indication ON, the mask indication is dislocated on approximately one unit out
of three hundred. As end users basically do not use panel mask indications, this is not a problem in normal usage. Dislocation
may be generated during failure analysis or when turning the unit off then back on during voltage margin adjustment.
2. On dislocation of the mask indication, which is generated on the right side of the screen
