Abstract

Se proporciona un dispositivo de visualización de cristal líquido capaz de mejorar el desenfoque de movimiento prevenir el flujo de corriente excesiva en una fuente de luz con un equilibrio deseado en una estructura donde la intensidad de luz de un dispositivo de luz de fondo se cambia apropiadamente en conjunto con la iluminancia de ambiente. Si la iluminancia de ambiente (S1) de un dispositivo de visualización de cristal líquido es inferior que una iluminancia predeterminada preliminarmente ajustada, un proceso de exploración de luz de fondo (proceso de iluminación intermitente) se implementa (Si de S2, S3), mientras que si la iluminancia de ambiente no es menor que la iluminancia predeterminada, el proceso de exploración de luz de fondo (proceso de iluminación intermitente) se termina (No de S2, S21). La intensidad de luz del dispositivo de luz de fondo se cambia en conjunto con la iluminancia de ambiente alta y baja al cambiar la corriente de conducción suministrada a la fuente de luz, dependiendo de la iluminancia de ambiente del dispositivo de visualización de cristal líquido y si o no implementa el proceso de exploración de luz de fondo (proceso de iluminación intermitente) (S4, S22).
