Hello,
I am using the STM32F746G-DISCO board with TouchGFX V4.20.0 and facing a
continuous display flickering issue.
Problem Description: Whenever I place images/widgets on the screen
at 1024x600 resolution, slight flickering appears intermittently.
Sometimes the display becomes stable for a few seconds, but after
some time the flickering starts again.
The issue is not limited to one specific image. Even with normal
images/widgets of resolution 1024x600, the flickering randomly
appears during runtime.
Board: STM32F746G-DISCO
Environment:
1. STM32CubeIDE Version: 1.10.1
2. TouchGFX Version: 4.20.0
3. Display Resolution: 1024x600
4. Image Resolution: 1024x600
Observed Behavior:
1. Small intermittent flickering on display
2. Flickering appears, disappears, and returns again
3. Display occasionally becomes stable temporarily
I have attached the datasheet of the display below for reference.
Could you please help identify the root cause of this flickering
issue based on the datasheet and suggest the correct LTDC timing
or configuration fix?
Thank you.
