7.3.19.1 Pattern Options

The DS90UH929-Q1 serializer pattern generator is capable of generating 17 default patterns designers can use for basic testing and debugging of panels. Each can be inverted using register bits (Table 8), shown below:

  1. White/Black (default/inverted)
  2. Black/White
  3. Red/Cyan
  4. Green/Magenta
  5. Blue/Yellow
  6. Horizontally Scaled Black to White/White to Black
  7. Horizontally Scaled Black to Red/Cyan to White
  8. Horizontally Scaled Black to Green/Magenta to White
  9. Horizontally Scaled Black to Blue/Yellow to White
  10. Vertically Scaled Black to White/White to Black
  11. Vertically Scaled Black to Red/Cyan to White
  12. Vertically Scaled Black to Green/Magenta to White
  13. Vertically Scaled Black to Blue/Yellow to White
  14. Custom Color (or its inversion) configured in PGRS
  15. Black-White/White-Black Checkerboard (or custom checkerboard color, configured in PGCTL)
  16. YCBR/RBCY VCOM pattern, orientation is configurable from PGCTL
  17. Color Bars (White, Yellow, Cyan, Green, Magenta, Red, Blue, Black) – Note: not included in the auto-scrolling feature

Additionally, the Pattern Generator incorporates one configurable full-screen, 24-bit color pattern, which is 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.
