I don't know about OLED and other fancy panels (like Micro LED, QLED, etc.), but for common LCD panels there are plenty of controller available to use them, even with 4K resolution [1]. And panels aren't difficult to find because they are used to repair other television. The problem here is to protect it about dust and dirt, also not having a convenient and easy to use user interface. IMO the best middle point is buying a LG Smart TV. They have Amazon Prime, Amazon Alexa, Netflix, and other platform installed, but IIRC you can uninstall this apps and you can't use them until you accept the terms and conditions. If you don't accept them you shouldn't worry about them. I haven't used Wireshark to know if that apps use the network even without using them, but at least isn't the same to some Samsung TV that insert ads in the menus when your TV is connected to the Internet.
