Example Embodiment

[0014] The present invention will be further described below in conjunction with the drawings.

[0015] Such as figure 1 As shown, a method for dynamically controlling the backlight according to the content of the mobile phone screen includes the steps:

[0016] A. The baseband chip sends control commands to the LCD controller LCDC;

[0017] B. The liquid crystal display controller LCDC collects the content displayed on the current mobile phone screen;

[0018] C. The LCD display controller LCDC outputs a PWM signal with adjustable duty cycle to the backlight drive controller LEDC according to the collected content;

[0019] D. The backlight drive controller LEDC outputs the corresponding backlight drive PWM signal to the screen backlight drive port according to the received PWM signal.

[0020] The liquid crystal display controller LCDC adopts a liquid crystal display controller with CUSTOM BLOCK function.

[0021] Said step A also includes: the baseband chip configures the CUSTOMBLOCK r...

Abstract

The present invention relates to a method for dynamically controlling a backlight according to contents of a mobile phone screen, the method comprises the steps as follows: A. a baseband chip sends a control instruction to a LCDC (Liquid Crystal Display Controller); B. the LCDC acquires the contents displayed by the mobile phone screen at present; C. the LCDC outputs a PWM (Pulse-Width Modulation) signal with an adjustable duty ratio to a LEDC (Light Emitting Driving Controller) according to the contents acquired; and D. the LEDC outputs a corresponding backlight driving PWM signal to a screen backlight driving port according to the PWM signal received. Compared with the prior art, the method in the present invention can dynamically control the backlight according to the different contents displayed by the screen without any extraneous interference, so that current consumption of the backlight is reduced, color of the screen display is bright and brilliant, and users can feel comfortable when watching the screen of the mobile phone.

Description

technical field [0001] The invention relates to backlight control DBC (DynamicBacklingtControll), in particular to a method for dynamically controlling the backlight according to the contents of the mobile phone screen. Background technique [0002] At present, the functions of mobile phones are becoming more and more powerful, and the power consumption brought by them is also increasing. Power consumption has become one of the important competition points of mobile phones. The screen backlight is a big consumer of mobile phone current. Under the premise of not affecting the user's senses, dynamically adjusting the brightness of the backlight is a good way to reduce the current consumption of the backlight. At present, the technology of dynamically adjusting the backlight according to the intensity of the ambient light has appeared in the market, but this technology still has some shortcomings, and it is greatly affected by external interference, such as users accidentally...
