Embodiment Construction
[0021] see figure 1 , figure 1 It is a flowchart of a backlight control method provided by an embodiment of the present invention. As shown in the figure, the backlight control method of this embodiment includes the following steps:
[0022] S101: When the user turns off the automatic backlight, collect the ambient light brightness, and at the same time acquire the backlight value set by the user under the ambient light brightness.
[0023] Wherein, before executing the method of the embodiment of the present invention, a preset step is further included, preset a plurality of ambient light brightness intervals, a backlight value adjustment range corresponding to each interval, and a sampling threshold for each interval.
[0024] In the specific implementation, the ambient light is divided into multiple intervals, from dark to bright, such as 0-20, 20-40, 40-60, 60-80, 80-100..., and the last interval is greater than a certain threshold ( Such as 1000nit). The adjustment ran...
