Abstract
A liquid-crystal display arrangement consisting of a liquid-crystal display, a light source constructed as a fluorescent lamp and a heat source which is thermally coupled to the fluorescent lamp. The heat source is formed as an essentially flat sheet on the side of the lamp opposite the display, with the heat source connected is series with a PTC type temperature sensor. In order to achieve a uniform and rapid establishment of the optimum operating temperature of the fluorescent lamp, the heat source is formed by a temperature-controlled foil-type heating element.
