Problems solved by technology

However, since existing mobile terminals have different sizes and generally have functions of horizontal and vertical screens, the following situations often occur in the daily use of mobile terminals: for example, in a certain fixed ambient light intensity Under the environment, the backlight intensity level should be adjusted to the highest level. At this time, if the user switches between landscape and portrait screens, and the light hole is blocked when holding the mobile terminal, the light sensor will be wrong because the light hole is blocked. It is considered that the current ambient light intensity has changed to a weaker level, so the backlight intensity level of the mobile terminal screen is automatically adjusted to the lowest level, but in fact the current ambient light intensity has not changed, and the backlight intensity level of the mobile terminal screen is adjusted to the lowest level Level, will lead to poor reading effect, users can not clearly see the screen content, which will seriously affect the user experience

Abstract

The invention discloses a mobile terminal backlight intensity accurately adjusted method, system and mobile terminal. The mobile terminal backlight intensity accurately adjusted method includes that when the mobile terminal receives a screen lightening request, the current ambient light intensity is collected through a light sensor and the level of the backlight intensity is adjusted according to the ambient light intensity; when the change of the current ambient light intensity is collected through the light sensor, the position state of a blocking object and a light hole is determined; if the blocking object is close to the light hole, a user can determine that the current ambient light intensity does not change and the existing level of the backlight intensity of a screen of the mobile terminal is maintained; if the blocking object is far away from the light hole, the level of the backlight intensity of the screen of the mobile terminal is readjusted according to the new ambient light intensity. According to the mobile terminal backlight intensity accurately adjusted method, system and mobile terminal, the light sensor is combined with a proximity sensor, so that the problem that the level of the backlight intensity is misadjusted due to the fact that the user blocks the light hole by accident is solved, the probability that the level of the backlight intensity is misadjusted is reduced to a large extent, and the reliable function experience is provided for the user.

Description

technical field [0001] The invention relates to the technical field of mobile communication; in particular, it relates to a method, a system and a mobile terminal capable of accurately adjusting the backlight intensity of a mobile terminal. Background technique [0002] In the prior art, the mobile terminal can intelligently adjust the intensity level of the backlight of the screen by using a light sensor. The ambient light sensor can sense the surrounding light conditions, and inform the processing chip to automatically adjust the backlight intensity level, thereby reducing the power consumption of the product and prolonging the working time of the battery to the greatest extent. When the ambient light intensity is weak, the backlight intensity level is low, and when the ambient light intensity is strong, the backlight intensity level is high. The current ambient light intensity is collected by the light sensor, and the backlight intensity level of the mobile terminal scre...
