Problems solved by technology

[0002] Current portable electronic devices are usually equipped with large-size, high-color display panels for multimedia requirements. However, for portable electronic devices, the control of battery power and the length of use time are very important to users. A high-color display panel must also consume more power, which undoubtedly consumes a lot of power for the battery
In the existing practice, usually when the system enters the standby (Idle) state, the backlight (Back Light) of the display panel will be turned off to save power. However, for the navigation system using the satellite positioning module, once the backlight is turned off, The characteristics of the display panel make it almost impossible for the user to see the navigation screen, so the system cannot turn off the backlight, resulting in the continuous consumption of a large amount of power by the display panel

Abstract

The invention provides a power saving system and method of a display panel. The system is suitable for a portable electronic device which at least contain a display panel, a satellite positioning module, a monitor module and a panel controller. The satellite positioning module provides an environment parameter, the monitor module is used for monitoring portable electronic device state and provides a state parameter, the panel controller can dynamic adjust brightness of the display panel according with environment parameter and state parameter.

Description

【Technical field】 [0001] The present invention relates to a power saving control system and method for a display panel, in particular to a system and method for saving power by dynamically adjusting the brightness of a display panel. 【Background technique】 [0002] Current portable electronic devices are usually equipped with large-size, high-color display panels for multimedia requirements. However, for portable electronic devices, the control of battery power and the length of use time are very important to users. A display panel with high chromaticity must also consume more power, which undoubtedly consumes a lot of power for the use of the battery. In the existing practice, usually when the system enters the standby (Idle) state, the backlight (Back Light) of the display panel will be turned off to save power. However, for the navigation system using the satellite positioning module, once the backlight is turned off, The characteristics of the display panel make it almo...
