Abstract

A thermosensitive display device including a thermosensitive material applied in a thin layer, and an array of resistors arranged on a thin flexible film. Each one of said resistors has a thin planar configuration and extends in the plane of said flexible film and essentially covers a square-shaped area. The resistors are arranged to emit host energy all over said square-shaped area when fed with electricity. The thin layer with thermosensitive material is applied directly in thermal contact with the thin flexible film. The device further including means for controlling the temperature in each of said areas.
