  • The reason I like Gray Jay is that it is source agnostic, so you can still use YouTube (because that is where the content is now) while also using other sources.

    I would like to see videos posted to ipfs.

  • But still getting off of YouTube as the source, right?

    Do I understand you correctly?

  • I think you will need a power supply for your panel in addition to a driver board like this. This only provides the signals needed to switch the pixels but not the power to drive them. Some of these include backlight drivers but even then I think you would probably need more current for a TV than these provide.

  • I retired from embedded systems design and design-for-manufacture a decade ago. Reading datasheets was most of the job. This doesn't look too daunting. It's a single interface between two readymade components. I've identified where some issues might come up, and there are probably some that I don't know about yet. Still this seems less like building a circuit around existing ASICs and more like hooking up stereo equipment to me.

  • Seems like a fun project to me too. It also seems like things have changed since the turn of the century, with regards to interoperability.

  • Why did you do it?

  • On Roku smart TV from Walmart. I was present in the returns line when a customer returned it because he wanted something to use with his Dish Network receiver and this one required he creat an account.

  • I can think of no better use for a TV

  • I don't think anyone repairs these things anymore. I found two dumped in the desert, one with its controller and power supply boards removed and one that was complete.

    I got interested in this when the previous poster asked the question. Going down the rabbit hole I think I have my answers. Avnet has some good info on the mipi interface for consumer devices. It's been very interesting and I do see it as a path to building good, cheap, large displays.

  • Or I could just accept my place and watch the ads and go along with all the caveats like a good consumer. I don't see that happening.

  • It seems like the current standard is MIPI DSI. This is my sourcee of information. I think it is doable.

  • Many smart TVs require you connect to create an account. More might in the future.

  • Why go through all of that when you can just connect the board to the panel.

  • So if anyone is interested I found the answer to my question. There seems to be two standards for LCD panels and there are these cheap converters for both of them.

  • I don't think this is edp or dsi out. Seems to be parallel 50 pin

  • Thanks. I searched for # Driver Board Universal LCD Monitor Screen Controller 5V Laptop Computer DIY

    Because I had seen them used for various projects before.

  • They are made for laptops, and I am sure they work there. There was a post here about 15days ago asking about unsmarting TVs but it has been deleted. That got me thinking about this solution.

  • Seems like something like Gray Jay is a very easy way to transition off of these sources, too. Just have a source agnostic player.

  • That's awesome. I will order one now for my wireless mouse.
