Kodak OLED Wireless Frame - digital photo frame (8506701)

Organic Light Emitting Diode (OLED) technology uses substances that emit red, green, blue or white light. Without any other source of illumination, OLED materials present bright, clear images and video that are easy to see at almost any angle.Active Matrix (AM) OLED displays stack up several thin layers of materials, including cathode, organic and anode, on top of another layer - or substrate - that contains circuitry. The displays operate on the attraction between positively and negatively charged particles. When voltage is applied, one layer becomes negatively charged relative to another transparent layer. As energy passes from the negatively charged (cathode) layer to the other (anode) layer, it stimulates the organic material between the two, which emits light visible through the outermost layer of glass.The pixels are defined by the deposition of the organic material in a continuous, discrete "dot" pattern. Each pixel is activated directly by a corresponding circuit. AM OLED pixels turn on and off indepe
