How do i connect THIS LCD screen, no touch
April 20, 2024, 16:02
I'm trying to use an old display from a Portable DVD player (used in cars). The display is a 7" 0004-JXY-A1 from Hannstar. It uses the same flatcable as the rasberryPi Camera so i thought maybe i could use this screen? Well i have some pictures attached to help you guys understand but when connecting the screen i ofc don't get an image. I need drivers or i think i could solder the screen to some pins, any ideas would be great. I do have another screen but rn i could not buy anything so i'm looking into doing it without buying other material.
I just found the screen i'm using https://nl.aliexpress.com/i/32848642439.html
Why did you remove the second ribbon cable? It connects the board at the back with the monitor...
I just disconnected it to make a picture, it's plug and play
Then there may be a lack of power.
The official display is connected with plus and minus to the pins of the Pi.
Another display that I use must also be connected via USB.
I don't think the Pi sends enough or any power at all via the display connection.
hmm will use another power brick, but i don't think it works like that 😄 if the power is indeed not enough... could i use the PI gpio pins?
This is the small board
As I have already mentioned, this is how it is done with the official display, so yes. I would start with 3 V and if that doesn't work go to the 5 V pin.
Update: i connected the backlight + - to the GPIO pins + needed 10V
So now i have this ... Could i also fix an image?
Is there an OS on the Pi?
Is the ribbon cable connected the right way round?
the ribbon cable is connected with the pins inward, there is raspberry pi OS on it
Then perhaps the Pi is missing the driver.
i think thats the problem couldn't find any driver anywhere
where should i find generic drivers ?
Mostly with the manufacturer of the devices. But it will be difficult with your display.
You just have to search the internet to see if there are any general drivers available. Unfortunately I have no experience.
try goodTFT on github
URL?
Could i install them all? And let the OS choose the right one?
Or is it try and error
there are instructions
Ddoes that driver work with wayland?
No idea it is a pretty generic driver so worth a try
Tested them all none did work
