FIELD: physics.
SUBSTANCE: method contains: obtaining the value of the ambient light intensity; determining, whether the intensity value is less than a predetermined threshold; enabling the night mode if the intensity value is less than a predetermined threshold, wherein the night mode is a display mode, in which the voltage of the shades of the gray liquid crystal screen is reduced in accordance with a predetermined coefficient. At the same time, when the night mode is the current display mode, obtaining the value of the ambient light intensity; determining, whether the intensity value is greater than a predetermined threshold value; and exiting from the night mode if the intensity value is greater than a predetermined threshold value.
EFFECT: providing automatic switching of the display mode to the night mode at extremely low ambient light brightness, dimming the screen is possible by decreasing the voltage of the gray liquid crystal display in the night mode.
