Problems solved by technology

[0004] However, the existing method for adjusting the brightness of the display screen only adjusts the brightness of the display screen according to the brightness of the ambient light, and cannot solve the problem that the brightness of the display screen is reduced due to the different observation positions of the user when viewing the display screen under strong ambient light conditions. problems, resulting in poor viewing effect of the user on the display screen, which in turn affects the user experience

Embodiment Construction

[0041] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0042] Such as figure 2 As shown, the method for adjusting the brightness of the display screen provided by the preferred embodiment of the present invention includes:

[0043] Step 11: When the ambient light brightness value of the display screen exceeds the set value, obtain the reference backlight data of the display screen according to the current ambient light brightness value.

[0044]The set value in this step is the preset value of ambient light brightness, which can be preset by the manufacturer of the smart mobile terminal. When the ambient light brightness value of the display screen exceeds the set value, it means that the display screen is ...

Abstract

The invention discloses a method and a device for adjusting the brightness of a display screen. The method comprises the steps of when a brightness value of ambient light in which the display screen is located exceeds a set value, acquiring benchmark backlight data of the display screen according to the brightness value of the current ambient light; acquiring location data of identification information in an image collected by facing the display screen, and determining compensation backlight data of the display screen according to the location data; and adjusting the backlight brightness of the display screen according to the benchmark backlight data and the compensation backlight data. According to the invention, the brightness of the display screen is adjusted timely according to the brightness of the ambient light, so that a user is ensured to also clearly see the content displayed by the display screen very well under a strong external ambient light condition, and the display screen watching effect and the use experience of the user are improved.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a method and device for adjusting the brightness of a display screen. Background technique [0002] With the continuous development of mobile communication technology, intelligent mobile terminals (such as smart phones, tablet computers, etc.) have become indispensable products in our life. At present, there are two mainstream display technologies used in smart mobile terminals, one is liquid crystal display (LCD, Liquid Crystal Display), and the other is organic electro-laser display (OLED, Organic Light-Emitting Diode). figure 1 Shown is a schematic diagram of LCD brightness observed at different display viewing positions, such as figure 1 As shown, the abscissa indicates the angle between the user's observation position on the surface of the display screen and the vertical direction of the display screen, and the ordinate indicates the observed brightness value of the...
