The All pixels on command (DAL) can be switched off by
sending the normal display on command (NORON); (see
Section 6.2.11) or by sending the partial Display mode on
command (PTLON); see Section 6.2.10. Furthermore DAL
is left with the command DALO; see Section 6.2.14. When
DAL is active all pixels are driven, as if the display RAM
was filled with all ones (on-state). DAL does not change
the data stored in the display RAM.

When sending DAL after PTLON, only the pixels of partial area are driven on. When sending INVON, in Partial mode only the pixels of partial area
are inverted. INVON is over-ruled by DAL and DALO. Pixels outside partial area always stay off.

When sending DAL after PTLON, only the pixels of the
partial area are driven on. When sending INVON in Partial
mode only the pixels of the partial area are inverted.
INVON is over-ruled by DAL and DALO. Pixels outside the
partial are always off. Figure 6 illustrates how DAL (all
pixels on) and DALO (all pixels off) can be used.
All pixels will be switched on regardless of the display data
RAM.
