Hello all
I am facing a problem with a 75 inch high brightness display from BOE. There is a brightness sensor which adjusts the brightness of the display to the ambient brightness. However, the sensor just always reduces by 60%.
I am looking for a solution to define the "reduction" of the brightness, e.g. from 3500 nits to 300 nits at dusk.
Is it possible to change the controller board to achieve this?
In the attachment you can see the initial situation.
Does anyone have a tip for me what I can do?
Thank you and best regards
Andrin
Welcome to the forum
Is this question related to Arduino in any way ?
Hello and thank you
No, not yet.
I hoped, that there is maybe a solution from Arduino, that could help me solve the problem.
Probably yes but without more information how is impossible to determine from your picture. What is that board from, can you post a schematic? What do each of the wires do? Without that information and more the answer would probably be no.
Thanks for your answer. i will try to give you more information. i will collect as much information as i can and come back with it.
Hey again
I have now tried to show the wiring of the boards as good as possible.
Did you mean something like that? or can not do anything with it?
(I made a pdf, but it is to big to post it here because of the pictures)
