Help Identity of 7 inch display

Good Morning,
I have in my spares box two AT070TN92 V. X 7 inch display units, I have a project which could use one but can't find much in the way of info.
For example which parameters do I use for the below example?

UTFT myGLCD(ITDB32S,38,39,40,41)

I have tried a couple and although the display starts it fades away into the blank screen. I am feeding with a large 5 volt source to the shield. It maintains voltage at a constant level.

I am using Artduino MEGA

Any information would be most helpful, Many thanks for reading my post.

For that size display, the controller is most likely the SSD1963 which can be identified visually and it is usually the largest chip on the display controller board.

I have read that you need to power 7.0 displays externally. A Mega powered via USB cannot supply enough current and the backlight fades out when the regulator goes into thermal shutdown.

If that doesn’t get you going, please post some decent resolution photos so we can see what you have.
