[Question]blinking and then dumped to be gray screen

jhpark

Hi, I'm using DMG10600T101_A5WTR and found some screen problems.

Symptoms:

After power on, soon a few flickering are happened and then dumped to be grayed screen.
I can't see anything from my screen(images/project) except gray and dot(s) on it,
and I guess I can't touch the my basic touch module on it.

Somtimes just VR_icon is remained as like my capture screen.
I want to upload my cature video, but I guess this board wouldn't support video


Is there any problem on my screen ?

Noting special. Actually, a simple project (which has only one background and basic touch module) has the same symptoms on my touch screen...

Pls kindly download the attached DWIN_SET to your screen to see if it is normal. And pls kindly take a screenshot for the blue downloading interface to have a check.

Thanks again !

I tried your new file and got a little different result.

- no flickering
- paryially broken and show grayed area on the reagion of broken
- touch is not working.. (maybe no touch function on this project ?)







How about the other checkpoints ?

1) 1A's current

I read the datasheet "DMG10600T101_A5WTR_数据手册.pdf"
and I'm using the power supply with 1A, is it enough ?

"推荐工作电源：12V 1A 的直流稳压电源
Recommended power supply: 12V 1A DC"

Because I heard there is a monitor with unstable or under current(power supply) can make the flickering..


2) OS binary files

And I also used below files when uploading the DWIN_SET folder.

- DWINOS_KONG.bin
- T5L_OS_V11_RTC(RX8130).BIN

I'm not sure those files are fit to my DMG10600T101_A5WTR,
but I found it from DMG10600T101-A5W.rar (from the dwin support sites).


Actually, I'm not sure above things can make this trouble but I'm trying to find most of doubts for now...

1. Firstly, pls kindly format SD card as below picture.
2. Then, pls kindly re-try the attached DWIN_SET (which changed 32.ICL to 30.ICL, put V55 kernal and configured erasing all off-chip flash contents in CFG flie).
3. For the touch function, already configured touch calibration in CFG file, the blue screen download interface will display a white+cursor.
To click on the top left corner, top right corner, bottom right corner, bottom left corner, and center to calibrate. Each + sign only click once, do not click repeatedly.
After finished clicking, power off - unplug the card - power on again.

I tried to format again (with fat32/4096bytes) and updated,
then I could see the + sign on left-top.
But I couldn't touch it ! I think there was no response from the screen..
Several times trials but there is no response after showing + sign..

Strange to say, I could touch the screen with normal application with basic touch module
but I couldn't at calibration.
I dont' know why...
