Light well for guiding light from organic LED to display element of display device of motor vehicle operating device, has inner wall whose surface consists of microstructures, where microstructures are formed based on crystal structure
The light well (2) has an inner wall whose surface consists of microstructures, from which light is scattered to all sides. The light well is injection molded part made of plastic. The microstructure is formed based on a crystal structure of titanium nitride or titanium aluminum nitride. The microstructures represent a negative of a tool surface, which comprises an expanded crystal. The light well is integrated in an orifice plate (1), which is produced as a plastic injection molded part. The orifice plate has recesses (6) through which light penetrates. An independent claim is also included for a method for producing a light well for a display.
