Display brightness self-adjusting device, method and intelligent wearable device

Abstract

The invention discloses a display brightness self-adjusting device, a display brightness self-adjusting method and an intelligent wearable device. According to the display brightness self-adjusting device, a light intensity acquisition unit is used for acquiring the light intensity of a surrounding environment, converts the acquired light intensity into a corresponding electrical signal value, compares the electrical signal value with a stored previous electrical signal value, and stores the electrical signal value if the change quantity of the electrical signal value and the previous electrical signal value exceeds a set threshold value, generates an interrupt signal and sends the interrupt signal to a central processing control unit; the central processing control unit is used for reading the stored electrical signal value when receiving the interrupt signal and controls a power source management unit according to the electrical signal value so as to make the power source management unit output corresponding power supply voltage to a display unit; and the display unit controls the display brightness of a display screen in accordance with the received power supply voltage. With the display brightness self-adjusting device and the display brightness self-adjusting method of the invention adopted, the automatic and humane adjustment of the display brightness of the display screen can be realized, so that the display brightness of the display screen can be suitable for ambient light intensity, and excessive power consumption caused by single brightness can be prevented, standby time can be prolonged, and user experience can be increased.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to a display brightness self-adjusting device, method and smart wearable device. Background technique [0002] With the popularity of smart wearable products, a variety of smart wearable products with screen display functions have emerged in the market. There are innovations and improvements in all aspects, but less attention has been paid to the automatic adjustment of display brightness in different environments. On the one hand, for smart wearable wristbands whose screen brightness cannot be adjusted, the brightness is the same in different scenarios (such as sunny outdoors, dimly lit underground parking lots, etc.), so that users cannot see the screen display clearly in bright environments, while In a dark environment, the screen display is dazzling, which affects the user experience; on the other hand, for products with always-on screens, a single brightness will lead to...
