Embodiment Construction

[0048] At first, the overall system of the present invention is described:

[0049] Such as figure 1 , the mobile phone backlight control system of the present invention includes the following functional modules:

[0050] (1) Processor

[0051] According to the user's operation and settings, read the light intensity data from the photosensitive device at a certain frequency when needed, and then combine the user's operation to analyze whether the backlight of the display screen and keyboard needs to be turned on, and generate multiple data and control signals after comprehensive processing. They are respectively transmitted to the display driver module, the display backlight control module, and the keyboard backlight control module.

[0052] (2) Display driver module

[0053] The data conversion sub-module in the display driver module performs a conversion process on the gray scale of the display data according to the received data A, and then transmits the converted displa...

Abstract

The invention relates to a mobile phone backlight control method which comprising the steps of triggering a sensor or a camera on a mobile phone to detect current environment luminance brightness according to an incoming call event or a key action event; adjusting a luminance value of a screen of the mobile phone according to the environment luminance brightness, wherein the higher the environment luminance brightness is, the higher the luminance value of the screen of the mobile phone is; and adjusting a display image of the screen of the mobile phone according to the environment luminance brightness, wherein the high the environment luminance brightness is, the higher an adjusting value is, and the adjusting value comprises a contrast adding value to low brightness pixel and a contrast lowering value to high brightness pixel. According to the mobile phone backlight control method, ambient light induction and image gray scale processing are merged together, ambient light, the displayscreen, backlight of the display screen and backlight of a keyboard are designed into a system, and the dynamic control of the system is conducted by a multipath and efficient adjusting method, so that the power consumption of the backlight is reduced to the largest extent on the premise of not influencing display effect and improving the experience of a user.

Description

technical field [0001] The invention relates to mobile phone battery energy management, in particular to a mobile phone backlight control method. Background technique [0002] At present, the power consumption of mobile phones has become a bottleneck in the improvement of mobile phone technology and functions. With the continuous enrichment and enhancement of functions, the power consumption of mobile phones has also increased step by step. However, in recent years, the storage capacity of mobile phone batteries has not been substantially improved, resulting in insufficient battery life. Therefore, the low The importance of power consumption technology is becoming more and more prominent. As an important power consumption factor of mobile phones, the reduction of backlight consumption is also of great significance. Contents of the invention [0003] The technical problem to be solved in the present invention is how to provide a mobile phone backlight control method, whic...
