Not a company, but sharing a personal project: I got a free broken 55" TV and turned it into a big daylight panel. I got a great explanation of why this works well (fresnel lens) from the DIY Perks channel on YouTube: Turning Smashed TVs into Realistic Artificial Daylight (https://www.youtube.com/watch?v=8JrqH2oOTK4).
The main board had failed so the screen was black and the backlight cycled on and off. After disconnecting the main board, the backlight stayed on. I am using the existing LED lights, but may replace them with the excellent color quality LEDs recommended by DIY Perks.
