Panel Dimensions
Non-display period
Frame Rate
Pixel Clock
These fields specify the panel width and height. A
number of common widths and heights are available in
the selection boxes. If the width/height of your panel is
not listed, enter the actual panel dimensions into the edit
field.
Manually entered panel widths must be a multiple of 16
pixels for passive (STN) panels and 8 pixels for TFT
panels. If a manually entered panel width does not meet
the above restrictions a notification box appears and
13505CFG rounds up the value to the next allowable
width.
It is recommended that these automatically generated
non-display values be used without adjustment.
However, manual adjustment may be required to fine
tune the non-display width and the non-display height.
As a general rule passive LCD panels and some CRTs
are tolerant of a wide range of non-display times. Active
panels and some CRTs are far less tolerant of changes
to the non-display period.
Select the desired frame rate (in Hz) from the drop-
down list. The values in the list are the range of possible
frame rates using the currently selected pixel clock. To
change the range of frame rates, select a different Pixel
Clock rate (in MHz).
Panel dimensions are fixed, therefore frame rate can
only be adjusted by changing either PCLK or non-
display period values. Higher frame rates correspond to
smaller horizontal and vertical non-display values, or
higher frequencies.
Select the desired Pixel Clock (in MHz) from the drop-
down list. The range of frequencies displayed is
dependent on settings selected on the Clocks tab.
