Abstract

La presente descripción describe un método de pantalla de cristal líquido y dispositivo los cuales pertenecen a un campo de pantalla de cristal líquido; el método comprende: adquirir un valor en escala de grises de cada pixel en un primer contenido desplegado en un panel de cristal líquido; y ajustar un índice de refrescar del panel de cristal líquido desde un primer índice de refrescar hacia un segundo índice de refrescar si el valor en escala de grises de cada pixel en el primer contenido es menor que un valor predeterminado, en donde el segundo índice de refrescar es menor que el primer índice de refrescar; esto permite reducir el consumo de energía del panel de cristal líquido y chip de pantalla en terminales, lo cual puede conservar más energía para las terminales, resolviendo así un problema técnico en la técnica relacionada donde se reduce la energía consumida por las terminales meramente disminuyendo la energía drenada por la retroiluminación.
