Summary

The four sides of the lamp shade are made from translucent LCD displays, and acrylic and paper diffusion layers. You can see the LCD display on the right is translucent, but similar to a pair of sunglasses, the polarizing film only permits a fraction of the backlight to emit through the panel.Polarizing film is necessary for the function of an LCD display.Given the low amount of light emitted through the display, to create a sufficiently bright lamp, a very bright light source is needed. Also, though an LCD display is typically backlit by a light with a cold color temperature (around 5000K), lamp light is typically a warm color temperature (like 2700K). The Jetson Nano is a powerful, tiny computer that operates on 5V power and can run a standard Linux distribution like Ubuntu.I wrote some custom software based on Pygame to display images, with a simple web app and server to give me control over the images.The LCD panels take EDP (Embedded DisplayPort) video input. These adapters are bulky and have a lot of functionality I didn’t actually need, like 12V power and brightness control for a backlight (which I removed from each panel) and a control interface for display settings.
