Mobile Display Brightness Control for Video Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face significant power consumption issues due to large-sized displays and high-resolution image processing, particularly when recording videos, as existing methods do not effectively manage brightness to reduce energy usage.
Innovation Solution
A method and apparatus that dynamically control the brightness of a display unit based on the resolution of the displayed image, using a control unit to identify the image resolution and adjust the brightness in stages, thereby reducing power consumption without altering the camera module's settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large-sized display unit is used to display high-resolution images, then image display quality is improved, but power consumption increases
Solution Approach 1:
The patent dynamically changes the brightness parameter of the display unit based on the resolution of the displayed image. When high-resolution images are displayed, the brightness is automatically reduced to a lower level, while when low-resolution images are displayed, the brightness can be higher. This parameter adjustment resolves the contradiction by maintaining acceptable display quality while significantly reducing power consumption during high-resolution video recording.
2Illumination intensity
If the brightness of the display unit is increased to improve visibility, then display quality is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the brightness parameter based on display content characteristics. During video recording, especially when high-resolution video is being displayed, the brightness is automatically reduced to a predetermined lower level. This resolves the contradiction by maintaining sufficient visibility for the user while significantly reducing the power consumption of the display unit during energy-intensive operations.
3Measurement precision
If the resolution of displayed video is increased to improve image quality, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent implements a coordinated control strategy where the brightness parameter is adjusted based on the video resolution parameter. When high-resolution video recording is detected, the system automatically reduces the display brightness to a lower level. This resolves the contradiction by maintaining high image quality for recording purposes while reducing the power consumption associated with displaying high-resolution content.

AI summary
An apparatus and a method for controlling a display of a mobile device are provided. The method includes identifying a resolution of video data to be displayed in a video display mode, retrieving brightness control data corresponding to the identified resolution from a memory unit that stores a plurality of values of the brightness control data each of which corresponds to each of a plurality of resolution values, and sending the retrieved brightness control data to a display unit to display the video data with specific brightness determined based on the brightness control data.
