step seven: adjusting the brightness of the active matrix; and adjusting the brightness of the display screen by adjusting the brightness of the active matrix according to the brightness adjusting value of the display screen in the step six, and if the brightness difference in the step six reaches the degree that the eyes of people cannot adapt to the brightness change, adjusting the brightness of the display screen again after 10s to restore the brightness adjusting value of the display screen to the brightness difference value.
In a preferred embodiment of the present invention, the second step and the third step are performed simultaneously.
As a preferable mode of the present invention, in the fifth step, if the ambient brightness is lower than the lowest value of the brightness range of the display screen, the display screen maintains the lowest brightness, and if the ambient brightness is higher than the highest value of the brightness range of the display screen, the display screen maintains the highest brightness.
As a preferable mode of the present invention, the interval time for adjusting the brightness of the display screen again in the step seven may be set as required.
The invention has the beneficial effects that:
1. the method for controlling the brightness of the display screen comprising the pixel active matrix is reasonable in design, when the ambient brightness changes, the brightness of the display screen can be adjusted according to the ambient brightness, the visibility of human eyes to the display screen can be guaranteed, the adaptability and the adaptation time of the human eyes to the overlarge brightness change are fully considered, and the experience of a user can be greatly improved.
2. When the method for controlling the brightness of the display screen comprising the pixel active matrix judges the six strong light environments, if the brightness difference reaches the degree that the eyes of people cannot adapt to the brightness change, the change quantity of the brightness adjusting value of the display screen changes along with the change of the brightness difference, so that the method has stronger adaptability, and the eyes can adapt to the problem that the display screen cannot be observed clearly caused by the change of the environment brightness more quickly.
3. The method for controlling the brightness of the display screen comprising the pixel active matrix has simple steps, and provides a brand-new display screen brightness adjusting method.
