It is feasible, the trick is finding a display with the same interface as your phone already has. You will then need to make a board to adapt from the flex cable you have to the flex cable on your new screen. On that board you will probably also need to provide power since it might not be the same. You will then need to modify the kernel, bootloader and Android to set the correct timing and resolution. (Timing, pinout and resolution for Linux kernel and U-Boot and resolution and DPI for Android)
Whats?

almost impossible .. should turn to professionals .. risk of damaging more

Hi!
Is it possible, through a software update, change the lcd gen? When I broke my Wizards lcd i took the lcd from my old Magician. They didn't have the same ribbon cable The lcd now works, but all colors are inverted or corrupted.
If not, is there a hardware change (except bying the correct lcd) that solves the problem? I'm used to soldering, so that shouldn't be a problem, however I'm not interested in moving any BGA circuits between the units.
Thanks!

It sounds to me like you might be s**t's creek with out a paddle on this one... I would reccomend just going on ebay and buying a new lcd and digitizer. If you are as good as you say you are, installing it should not be a problem but from the sounds like the 2 different screens are not compatible at all due to the different ribbon cables.
I would say you have 2 options.
1. Deal with the messed up and inverted colors.
2. Buy a new lcd and digitizer.
Now comes the hard part... Deciding...
Hey guys, I'd appreciate your input on this idea.
I have a G1 that was run over by a car. The screen is, of course, completely broken, but the rest of the hardware works properly (charges, adb, etc.).
I also have an old Asus S5n laptop with an awesomely thin lcd display, but with a fried video card.
I have relatively no experience with laptop or phone internals, so here is my question:
How plausible would it be to build a G1-powered tablet using the provided hardware along with a touch panel kit and perhaps a modified android kernel?
getting the Asus screen to display the output of the G1 phone will be a miracle and if it is done...ur probable half way there.
good luck with that
Soo... the only ways I can think about going about doing this is getting a proper LVDS driver for the laptop display (quite possible but expensive [$200+]) and then getting the video output from the G1. I'm not sure that's possible but I remember seeing someone somewhere doing that... could be wrong (hopefully).
Even if you were able to do all of that, you would be lacking input as the touchscreen wouldn't really be augment-able.
Either way, good luck with your project1
I have an idea for a project that requires a large panel to be attached to a small phone, does any one know if this is possible.
I know from previous projects that the galaxy line phones seem to have similar cables and connectors but , for example, could I plug a note screen into a GS2? I know the ribbons wont be in the right place and it will be bodged together but that isn't important. What is important is will they physically connect??
My hardware knowledge is good but by software side not so good. I know that android is capable of adapting to different resolutions but will this work "out the box" or will the resolution need changing in the build,prop, or maybe more??
any ideas on this please share, I think this is quite an exciting project that I will share and colabarate with if it is feasable. Its still at the rough concept stage at the moment and I am just checking out the theory behind it so please share your knolage and experience

It is feasible, lots of screens use similar interfaces (parallel TTL, MIPI, LVDS, etc.) so the trick is finding a display with the same interface as your phone already has. You will then need to make a board to adapt from the flex cable you have to the flex cable on your new screen. On that board you will probably also need to provide power since the new screen will consume more power. You will then need to modify the kernel, bootloader and Android to set the correct timing and resolution. (Timing, pinout and resolution for Linux kernel and U-Boot and resolution and DPI for Android) Shoot me a PM, I do this kind of stuff as a consultant and I am happy to give you some pointers!
Hello,
I recently replaced the screen on my 6T after breaking it. After putting everything together and booting back up, I'm having an issue where the whole screen will flash black momentarily, like clockwork, every 5 seconds exactly.
The issue is not present in recovery or bootloader screens, only once it has booted up into the OS.
I was running RR to begin with, have since done a full wipe and flashed to liquid, issue persists..... I'm completely baffled.
Any ideas?
Try using manual brightness control, but I think that cycles at much faster intervals.
The mobo may have been damaged. Any impact that can break the display can potentially crack solder joints, break pcb traces even cause internal damage to chipsets or components.

You're correct, manual brightness control does note affect it.
I guess it is possible that the mobo was damaged, however, would that explain why it doesn't have this issue in recovery mode? I would think that whatever components are used to control the screen would be the same, so the difference between recovery and OS really throws me for a loop.

I don't know why. Sound annoying though.
Playing with more might yeild more clues.
Maybe the display it's self.
Are you sure all the connections are good especially the ground and V+? Displays draw a lot of current.
Manufacturers use various techniques to connect subassemblies together, most common are ribbon cables but could be a screw, contact pad, the frame rail etc.
Assembly exactly the way in was and closely inspect all contact pins, sockets and surfaces.
Hello folks,
I guess this is the most appropriate subforum to ask this kind of question.
I'm having a broken screen Samsung Galaxy Note 5. And instead of find a touch screen replacement, I want to just get rid of the screen entirely
and instead connect the board to external monitor via hdmi interface preferrably. I believe the part that connect the touch screen is called "LCD fpc connector", correct me if I'm wrong.
So I guess I need something like an adapter that convert "fpc connector" to "hdmi connector".
The question is, is this hack possible? can the phone board output to hdmi monitor at all?
If yes then how to do it properly.
Please englighten me, I'm a total noob on this
Many thanks!
Hey huannb,
I also wanted this badly enough to stumble upon your post. From the light research i have done so far, it seems like this is a project only for those who have well labeled board diagrams and a deep understanding of LCD driver technologies.
FPC stands for "Flexible PCB Connector" and it's usage is ubiquitous in the small form-factor electronics space. If you are working with a FPC connector, you are probably handling a one-of-a-kind engineered interface. There are some hardware hackers who have achieved great feats such as THIS JAPANESE HARDWARE HACKER who build a driver board to adapt iPad retina displays to HDMI. I haven't stumbled on a write-up depicting and FPC interface to HDMI conversion yet. If you find one, please post it here because i would like to meet the person responsible for making it.
The way i see it, we have two choices from here. Reverse engineer a device and build a snowflake adapter which only works on one device, OR recycle the device and continue to live within the realm of consumer hardware.

Hi,
Thank you very much for your insight, it is super helpful and somewhat deep enough for me .
It does seem to involve quite a lot of hacking and there isn't a universal approach.
For my case, it is not worth the effort anymore, I have found a way to use most android mobiles to external monitor without fixing the screen itself without much complications.
I doubt that I can find anyone competent enough to explore this realm any further .
Thank you so much again for your research. Cheers
