UI Application Guidelines
3.3.1
Pattern design
Suggest the background is a picture to avoid using a gray pattern, If you really need
a gray pattern, use the "GC16" mode for a clear image.
3.3.2
Waveform information
Advantech pairs the display and driving board by production lot, display size, and
waveform type in production, so do not re-pairing to different driving boards and pan-
els with different shipping and packages.
3.3.3
Waveform "Init mode"
Only use on boot up, could not use at pattern transition. Or it will harm the panel eter-
nity.
3.3.4
Waveform mode in signage
INIT (Global update WF)
Initialize is used to completely clear the display, if it's left in an unknown state. (i.e. if
the previous image has been lost by a re-boot).
DU (Local update WF)
Direct update Non-flashing waveform that can be used to update. It can update any
changed gray tone pixel to black or white only.
GC16 (Global update WF)
Grayscale Clear, 16 Levels A "flashy" waveform used for 16 level grayscale images.
All the pixels are updated or cleared.
GCC16 (Global clear update WF)
Grayscale Clear, 16 Levels A "more flashy" waveform used for 16 level grayscale
images. All the pixels are updated or cleared.
This provides the best image appearance.
A2 (Local update WF)
Animation, 2 Levels is a non-flashing waveform that can be used for fast updates
and simple animation.
This waveform support black & white updates only.
Image quality and ghosting is reduced in exchange for the quicker response time.
GL16 (Local update WF when white to white, Global update when 16 gray levels)
The GL16 waveform is used to update anti-aliased text with reduced flash. GL16
should be used only with Full Display Update.
The entire display except pixels staying in white will update as the new image is writ-
ten. The GL16 waveform has 16 unique gray levels.
