Pat 1. Displays an all white screen for verifying the light output
of the
display and checks for color purity.
Pat 2-4. Displays a red, green, and blue pattern for verifying the
color purity of the display and also the ability to independently control
each color.
Pat
5. Displays an all black screen. This is used to check for
stuck pixels.
6. Displays a
gray
for verifying that the
GSP
board can produce 16 different amplitudes of color (in this case, white).
The output comes from the RAM on the GSP board, it is then split. The
signal goes through a video DAC and then to an external monitor or
through some buffer amplifiers and then to the internal LCD display.
If the external display looks good but the internal display is bad, then
the problem may be with the display or the cable connecting it to the
GSP board. This pattern is also very useful when using an oscilloscope
for troubleshooting. The staircase pattern it produces will quickly show
missing or stuck data bits
Test Pat 7. Displays the following seven colors: Red, Yellow, Green,
Cyan, Blue, Magenta and White.
8. This pattern is intended for use with an external display.
The pattern displays a color rainbow pattern for showing the ability
of the
GSP board to display 15 colors plus white. The numbers
written below each bar indicate the tint number used to produce that
bar (0
red,
green,
blue).
9. Displays the three primary colors Red, Green, and Blue at
four different intensity levels. You should see 16 color bands across
the screen. Starting at the left side of the display the pattern is; Black
four bands of Red (each band increasing in intensity) Black four bands
