STK6005 Datasheet, PDF (14/36 Pages) List of Unclassifed Manufacturers – converting PC / Mac video images for a TFT-LCD display monitor

STK6005
The panel output window are defined by the following registers: PHSW, PHDE1, PHDE2, PHXDE1,
PHXDE2, PHT, PVSW, PVDE1, PVDE2, PVXDE1, PVXDE2, PVT. The output timing are referenced to
the leading edge of PHS and PVS. The horizontal timing is counted by number of output pixels and the
vertical timing is in output display lines.

5.7 Scaling Control
The input image can be independently scaling up and down in both horizontal and vertical directions.
The scaling ratio for each direction is in the range of 0.5x ~ 16x. The registers HSR and VSR control the
output scaling ratio for horizontal and vertical directions respectively. The formula to calculate the values
of HSR and VSR are shown below:
