A screen brightness adjustment method and user terminal

Abstract

The embodiment of the invention discloses a screen brightness adjusting method and a user terminal. The method comprises the steps that a first environmental light intensity value of the current light environment is measured through a first light sensor, and a second environmental light intensity value of the current light environment is measured through a second light sensor; brightness of a first backlight source matched with the first light sensor is adjusted to be consistent with the first environmental light intensity value; the brightness value of a backlight source corresponding to the second environmental light intensity value is inquired in the corresponding relation between pre-stored environmental light intensity and brightness of the backlight source based on the second environmental light intensity value; and brightness of a second backlight source matched with the second light sensor is adjusted to be the brightness value. With application of the screen brightness adjusting method and the user terminal, accuracy of the detection result of external light environment can be enhanced, and the display effect of the user terminal screen can also be enhanced.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a screen brightness adjustment method and a user terminal. Background technique [0002] With the rapid development of user terminals (such as smart phones and IPADs) and the improvement of people's spiritual life, people are more and more fond of using user terminals for various leisure and entertainment, such as watching videos, reading novels, browsing the web, playing games, and so on. Usually, the brightness of the screen of the user terminal is a key factor affecting the viewing of the user. When the ambient light intensity is strong (such as under the sun), the light irradiates the user terminal screen and is reflected to the human eyes, which easily makes the user unable to see the content displayed on the screen. When the ambient light intensity is relatively dark (such as in the dark), The brightness of the screen of the user terminal will become ...

Problems solved by technology

However, it has been found in practice that since there is only one light sensor on the user terminal, and the device works with reference to the error and jitter of the power supply, the same light sensor may detect different results at different times under the same brightness. When the external light environment remains unchanged, the accuracy of the detection result of a light sensor is not high, and then adjusting the screen brightness according to the detection result with low accuracy will make the display effect of the screen not good
