Abstract

Se describe un dispositivo de visualización de cristal líquido que tiene una función de atenuación local capaz de reducir la percepción de extrañeza dada a los espectadores provocada por el escape de luz. Una unidad de control de visualización de imagen (12) controla la relación de apertura de los píxeles de cristal líquido externos del área de visualización de imagen para que sea un valor predeterminado. Una unidad de control de retroiluminación (14) controla el valor de brillantez de los elementos de emisión de luz que iluminan una región externa del área de visualización de video para que sea un valor predeterminado en respuesta a las señales de control salidas a partir de la unidad de control de visualización de imagen (12). Un dispositivo de visualización de cristal líquido (1) controla la brillantez de la región externa del área de visualización de video para que sea un valor predeterminado en función de la correlación entre la relación de apertura de los píxeles de cristal líquido externos del área de visualización de video controlada por la unidad de control de visualización de imagen (12) y el valor de brillantez de los elementos de emisión de luz que iluminan la región externa del área de visualización de video controlada por la unidad de control de retroiluminación (14).
