About the GP270-SC31-24V
This panel is an STN color LCD that supports the following colors white, magenta, blue, cyan, red, yellow, green, and black (a total of eight [8] colors). The tiling patterns in this panel make the blends of these colors possible. There are eight (8) levels of contrast adjustments available for the screen. The character size on the screen (both height and width) can be expanded by 2, 4, or 8, which does change the character display. The GP270-SC31-24V's touch panel also has 16x12 keys/screen with one or two-point touch.
