7.3.21.1 Pattern Options
The DS90UH949A-Q1 serializer pattern generator is capable of generating 17 default patterns for use in basic testing and debugging of panels. Each can be inverted using register bits (Table 10) shown below:
- White/Black (default/inverted)
- Black/White
- Red/Cyan
- Green/Magenta
- Blue/Yellow
- Horizontally Scaled Black to White/White to Black
- Horizontally Scaled Black to Red/Cyan to White
- Horizontally Scaled Black to Green/Magenta to White
- Horizontally Scaled Black to Blue/Yellow to White
- Vertically Scaled Black to White/White to Black
- Vertically Scaled Black to Red/Cyan to White
- Vertically Scaled Black to Green/Magenta to White
- Vertically Scaled Black to Blue/Yellow to White
- Custom Color (or its inversion) configured in PGRS
- Black-White/White-Black Checkerboard (or custom checkerboard color, configured in PGCTL)
- YCBR/RBCY VCOM pattern, orientation is configurable from PGCTL
- Color Bars (White, Yellow, Cyan, Green, Magenta, Red, Blue, Black) – Note: not included in the auto-scrolling feature
Additionally, the Pattern Generator incorporates one user-configurable, full-screen, 24-bit color controlled by the PGRS, PGGS, and PGBS registers. This is pattern #14. One of the pattern options is statically selected in the PGCTL register when Auto-Scrolling is disabled. The PGTSC and PGTSO1-8 registers control the pattern selection and order when Auto-Scrolling is enabled.
