Embodiment Construction

[0026] Various example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.

[0027] figure 1 A flowchart showing a method for adjusting screen brightness of an electronic terminal according to an exemplary embodiment of the present invention. As an example, the electronic terminal may be an electronic device capable of adjusting screen brightness, such as a mobile communication terminal (eg, a smart phone), a tablet computer, a personal digital assistant, a digital multimedia player, and a portable wearable device.

[0028] refer to figure 1 , in step S10, the brightness value of the current display content on the screen is detected. Here, the brightness value may be an average value of grayscale values ​​of each pixel when the screen presents the current display content.

[0029] Preferably, the brightness value of the current display content can be determined in the following manner: divide...

Abstract

The invention provides a screen brightness adjusting method and device of an electronic terminal. The screen brightness adjusting method of an electronic terminal includes the steps: detecting the brightness value of the current displayed content of a screen; determining the backlight brightness standard value of the screen, corresponding to the brightness value of the current displayed content of the detecting screen; and adjusting the backlight brightness of the screen as the determined backlight brightness standard value. The screen brightness adjusting method and device of an electronic terminal can adjust the backlight brightness of the screen according to the displayed content of the screen of the electronic terminal, thus according with the brightness demand of a user, and saving the brightness loss of the system.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a method and device for adjusting screen brightness of an electronic terminal. Background technique [0002] At present, the existing methods for adjusting the brightness of the screen of the electronic terminal mainly include: sensing the intensity of the ambient light by the ambient light sensing element of the electronic terminal, thereby automatically adjusting the brightness of the screen according to the intensity of the ambient light. When using the above method to automatically adjust the screen brightness of the electronic terminal, generally the screen brightness is set higher, and higher screen brightness will lead to increased power consumption of the system. [0003] In addition, the brightness of the screen can also be adjusted manually. At this time, the brightness of the screen backlight cannot change with the change of the light intensity in the...
