One pixel is stored in two bytes of display buffer as shown below:
Bit 13 Bit 12
Red Bit 3 Red Bit 2
Bit 5 Bit 4
Green Bit 0 Blue Bit 4
As shown above, the 32768 color pixel is divided into four parts: five bits for red, five bits for green,
and five bits for blue and one reserved bit. The output bypasses the LUT and goes directly into the
Frame Rate Modulator. Although 15 bit-per-pixel only make sense for a color panel, this memory
model can be set on a monochrome panel, however only 16 shades of gray will be visible.

As shown above, the 65536 color pixel is divided into three parts: five bits for red, six bits for green,
and five bits for blue. The output bypasses the LUT and goes directly into the Frame Rate Modulator.
