8. Troubleshooting
This section addresses common issues and provides solutions.
8.1. General Issues
- Q: The display is not turning on or showing unexpected behavior after assembly.
- A: Ensure that the display module has been properly programmed and tested before assembly. It is crucial to update the program to the LCD first. Verify all power and data connections are secure and correctly wired according to the pinout diagram (Figure 4.1).
- Q: Screen flickering is observed.
- A: Check the brightness setting. If the brightness is adjusted to 1%~30% of the maximum brightness, flickering may occur. It is not recommended to use the display in this brightness range. Adjust the brightness to a higher level.
9. User Tips
- Development Workflow: Always follow the recommended development workflow: check the software platform, use the correct SDK, update the program, test thoroughly, and then assemble. This prevents potential issues and saves time during integration.
- Brightness Settings: For optimal visual performance and to avoid flickering, maintain the display brightness above 30% of its maximum capacity.
- Technical Resources: Utilize the extensive online resources provided by DWIN, including their developer forum, international website, development tools, guides, and video tutorials, for any development or technical queries.
