OLED (Organic Light-Emitting Diode) technology generates crystal-clear images using self-lighting pixels, extremely effective organic light-emitting diodes. In contrast to LCDs, they do not require back lighting. Each and every pixel produces light. When the pixels are switched off, the result is an intense and complete blackness. With a response time of less than a microsecond. The absolute blackness with no trace of any blooming effect makes colours look more vibrant and brilliant than ever - authentically reproducing even the finest nuances of night scenes. OLED offers flawless, crystal-clear picture quality, with rich contrasts from a direct or lateral viewing angle. Fascinating picture experiences, pure television pleasure. Thanks to Dolby Vision™, the bild 4 produces brilliant high dynamic resolution (HDR) images with an authentic colour spectrum and a whole new level of depth.
