NUBI jewels allow autonomy between 7h and 20h. The autonomy of your jewel will depend on:- Colors present on the image or animation (dark or light)- The choosed brightness level

We use OLED displays. By displaying an image with adequate brightness, the digital dimension of the jewel is no longer perceptible: the display look like glass. When working on your images, we recommend avoiding large areas of white, the rendering of which is less natural, unlike black, which on our display corresponds to true black: no light is emitted by the pixels.

Thanks to the small ambient light sensor located on the left side of your jewel, NUBI automatically regulates the brightness of the display according to the ambient light. So after having adjusted the brightness of your jewel according to your tastes, you can change the lighting mood (go from a lighted room to a darker room) without the brightness rendering of your jewel changing.
