Touch
Used for mapping touch ADC values to display pixel co-ordinates.
[4096, 4096] --> [320, 240]
[RawX, RawY] --> [PointX, PointY]
Usually [PointX0, PointY0] is placed around 25% from the top-left corner, and the same for [PointX1, PointY1] except 25% from the bottom-right corner.
This offsetting is needed because the touch film starts to distort outside of that rectangle, which would skew the touch results near the center of the screen.

ULCD delay
There is a delay between switching the parallax barrier, and adjusting the backlight.
These delay values determine how many VBlank events to wait on before switching the backlight curves to the appropriate mode.
This is needed only to prevent epillepsy from analog jitter causing unwanted mode switches, and both values are usually always set to 1 or 2.
