LED Full Color Display Flashing Causes and Solutions
Although the LED full-color display flash is not a big problem, but it is a headache problem, not only affect the quality of the playback screen, but also affect the user’s mood, then the LED full-color display flashing reason is how is it? Is there any good solution? The following is the joint technical team to share some of the information, together to see
LED full color display flashing reasons:
1. Driver loader is wrong
2. Computer and the screen between the Hu line is too long or cable failure
3. The sending card is broken
4. Bad control card, look at the control card on the small light it? If it is not bright on the bad.
5. The connection between the power supply and the control card is shorted.
6. The output voltage of the power supply is unstable, and the power supply with the control card should not bring too many boards.
LED full color display flashing Corresponding solution:
If it is the whole point of the screen, the image of the new move, the driver is usually not loaded, re-check the driver loader, it is not unloading reload
There is a possibility that the sending card is broken, this time you need to replace the send card
If it is irregular flicker, the general is the system frequency problem. Replace the system, or adjust the settings parameters, the basic can be resolved!
If it is a little bit of flashing state, there may be graphics card driver problem, there may be sending card resolution settings.
Another possibility is the power supply problem (power supply shortage, information clutter, electromagnetic interference), the design of PCB to consider the power and signal traces of the wire diameter, and PCB production process. There are some improvements in the number of capacitors on the module.
If the text is flashing with the text (there are irregular white side of the text, irregular flashing, the text disappears after disappearing), this is the graphics card set the problem, in the display properties to cancel the “menu under the hidden”, “edge smooth transition effect” The Can solve such problems.
