Abstract

La presente descripción se relaciona con un método para ajustar una pantalla de cristal líquido y un aparato, para mejora el brillo de la pantalla de cristal líquido; el método incluye: cambiar un valor en carga a través de un circuito de fuente de la pantalla de cristal líquido, y medir transmitancias de la pantalla de cristal líquido a diferentes voltajes en carga; determinar un voltaje en carga correspondiente a una transmitancia máxima de la pantalla de cristal líquido de acuerdo con una relación correspondiente entre el voltaje en carga y la transmitancia; y determinar un voltaje de operación del circuito de fuente de acuerdo con el voltaje en carga correspondiente a la transmitancia máxima y, ajustar el voltaje en carga a través del circuito en fuente con el voltaje de operación; la presente descripción puede incrementar la transmitancia de la pantalla de cristal líquido al ajustar un voltaje de operación del circuito de fuente a un voltaje correspondiente a la transmitancia máxima de la pantalla de cristal líquido y, después incrementar el brillo de la pantalla de cristal líquido, por lo que el brillo de la pantalla de cristal líquido se puede incrementar sin cambiar la estructura de la pantalla del cristal líquido.
