Abstract

Instrumento de representación, especialmente para un automóvil, con una pantalla-TFT que presenta un primer substrato y un segundo substrato, y con un sensor para la determinación de la claridad ambiental, estando insertada entre los substratos una substancia de cristal líquido y el primer substrato presenta transistores de película fina en su lado dirigido hacia la substancia de cristal líquido y el segundo substrato presenta un contraelectrodo en su lado dirigido hacia la substancia de cristal líquido, caracterizado porque el sensor (5) está dispuesto en la pantalla (2) entre el primero y el segundo substrato.
