T6963C 240x128 LCD display problem with connecting to arduino uno

Other Hardware Displays
1

I have two LCDs, RA6963 and T6963. RA6963 connects and works flawlessly with arduino. However, the T6963 is completely unresponsive. I've tried all possible libraries and output methods, but the result is the same (RA6963 works, T6963 doesn't). Datasheets are exactly the same for both displays. I will be grateful for your help.

Maybe your T6963 is faulty? Replace it and see if that fixes the problem.

For more detailed advice, try reading the forum guide in the sticky post at the top of most forum sections.

I am completely sure that it is working. (This display outputs information using another controller)

I have no more suggestions based on the information you have shared so far.

Provide links to the site you bought the displays. Provide pictures of the backside of both displays.

It could be as simple as different backlight control.

Which one? using read ID method? Or do you mean to say something else?

@OlegLysiak, thank you for the details!

Doesn't look so, at first sight.

Thanks for the details provided, I now understand that these are matrix displays.
I do have some matrix displays, but much simpler ones.

My current knowledge is far behind of what would be needed to try to help you. Sorry.

But with the added information maybe someone else gets interested.

Good Luck!

Thanks, but already checked that.

I found a solution. The T6963 is an older model, so it required more current

Thanks.

NOTE: If you have the same problem, you can try doing a C/D inversion (It's different on some displays)
